I'm trying to convince my school into getting a G5 over a dell 3GHz P4. What are the advantages the Mac has over the dell for DV editing? (Hardware and software wise.)

Price has to be comparable with the dell, so it would probably be the 1.6 G5.

Try to get the 1.8 GHz, only $400 more for twice the RAM maximum, and more speed.
Hardware:
RAM
faster system bus (not sure about the 800 MHz bus one, may be equal)
Superdrive (dunno if Dell has one)
Probably faster (Dual 2 GHz definitely faster)
Better for multitasking

Software:
Final Cut
OS X (works better, can't crash)

G5: well, the G5 will be better equipped to handle video editing right out of box. The G5 has iMovie and iDVD- two great products. Also, the G5 would have a DVD-R/RW drive, which is more compatable for set top DVD drives. The G5 has betetr options for low and middle budget- though high end- editing software. Final Cut Pro 4, as we all know, just makes PC editing programs look like a panzy. Only Adobe Premiere comes close, and that isnt even really that good. Also, though untested, the G5 probably has better encoding times than the Dell, especially with the optimized iMovie or Final Cut running.

Dell: The Dell comes with some crappy Pinnacle lite program and some Sonic DVD burning app with a ton less power than iMovie and iDVD and with a ton less integration between them. The Dell also would come with a DVD+R/RW drive, a risky thing to get if you want to play your disks in a set top (some play it, some dont) The Dell, though it has the fastest availible Intel chip, probably doesnt have faster encoding times than the G5 and the programs availble for editing are either 50000$ or 100$. The only quality, mid-range video editing program is Adobe Premiere. DVD burning is probably the least of your PC concerns, as you probably only need to make simple menus and burn it. Nothing super complex needed in that area.

My recommendation: G5

Even at 1.8 Ghz on single proc, it would probably be on par with the Dell in price and speed. Knock up the RAM a ton and you have yourself a kick arse video editing machine- complete with a Geforce Fx 5200 (no Radeon 9700, but this is not a gaming rig, so who cares). Just add you choice of monitor[s] and be happy :)

can the dell handle 4 gigs of ram? or 8 gigs?

I doubt it. It is my understanding that the more ram you have in a video editing machine the easier and faster it is to edit. Having said that, the programs for Mac are also much cheaper and more efficient then their PC counterparts.

go mac.

youre right. If possible, you could hold a large portion of your compressed, but raw dv footage in the RAM. (dv tape holds 11GB compressed) Wouldnt that be awesome? Encoding from a source that almost instantaniously feeds data. Wow, sheer brillience.

FCP 4 is a major plus for the G5, but does not compete with Premiere, it's angled at DV xpress Pro by Avid. The only problem is that DV xpress Pro is expensive alone, plus if you add the standalone accelerator (Mojo) to it, then you're looking to add significantly to your costs. Since the computer will be for a number of users, by far your best bet will be the G5 as not only can you run FCp 4 on it, but you also have a solid beginner oriented software package in iMovie, which isn't to say that it alone would not sufficiently meet your DV needs in a high school. Finally, it has been my experience, over and over again, that working with video on a Mac is far more stable than on a PC.

With FCP 4, you have an amazing software package at a great price, on a solid platform. Not the same with DV xpress Pro.

kinda right. FCP is aimed at Avid. Period. FCP is completely resolution independent which means it can do everything from DV to Hi-Def. And this makes it an increbilby flexible program sense it can "grow" as your needs grow.


Tazo,
your understanding is kinda right. ;) Having more RAM will not help you out speed wise unless you just don't have enough RAM to run the editing program properly. A faster proc will lower your render times and suffciently fast HDDs will help make sure you don't drop frames, but more RAM will just give the flexibility to run more programs at once w/o the system bogging down. The exception to what I just said is FCP 4 which is supposed to use all parts of the system (GFX card, HDDs, RAM, and Prco) together to expand the RT abilities of FCP. Sense FCP 4 is still so new I haven't found an all inclusive review about it so whether or not RT Extreme lives up to it's hype is yet to be determind.


G5orbust,
I fail to see the advantage of holding a small amount of DV video in RAM? Current 7200PRM P-ATA HDDs are more than fast enough handle the data rate of DV. Or maybe I'm misunderstanding you point?

hardwarewise is not as important as software.
and software is where the mac has the clear advantage.
if speed and ram limit is important to you then there will always be something faster in 3 months.
i would even choose the dual 1.25 with superdrive over the dell even though it would be slower at many things then the p4 and single G5's, but probably faster a mp aware apps. and dont forget the price of 1GB chips.
software and eas of use should be first consideration, then expansion, then speed and ram,
take the crew to the apple store when they have a demonstration of idvd,imovie and the amazing final cut/express and logic 6 and soundtrack.
let the hardware be second to the software and show them some of the work done by others on the mac.

Plus, schools can get an education discount. Just got to the Apple Online Store, and click on education. Then choose your school. Hardware and software are much cheaper.

Don't let them get a Dell for DV. I know from experiance. We could never burn DVDs right from our new Dells at work. You can edit with a PC, but it's a pain, even if it is a little faster (debatable). Do a net search, show the person responsible some good examples.

What school, and how much can they spend?

HA HA HA HA HA
4 Gigs - no way - be lucky to get three in there. The PC will not hold as much RAM as a G5 for some time to come. The G5 is 64bit. That is why the RAM is limited to 4TB.


TB = 1 024GB
GB = 1 024MB

TB = 1 048 580MB

Having used the PC for DV editing I must say that the Mac is definetly better. With all the PC machines I've never been able to render in Premiere while doing other tasks. However, in even my single processor G4 I can render, surf the net and chat. Just if you get a Mac, make sure you get an external drive. Internal Mac drives have been slower compared to their PC counterparts and you wouldn't want to slow down your internal with video data. I suggest an ADS drive kit (www.adstech.com) that way you could always upgrade your HD space.

I agree, the software is what counts and there is nothing that even comes close to competeing with Final Cut Pro or iMovie in their respective price ranges. But I disagree with going witht the Dual 1.25, the G4s have massive bottlenecks and the G5 improves this emensely. You want all of the processor time to go to the video program and the G5 will allow you to do this. The Dual 2Ghz would be sweet, you might be able to convince them that it will last a lot longer than any other computer you can currently buy for that price. It might actually save you money in the long run (and I think it will).

Like what has already been said before, RAM is very important, because although hard drives are fast, they're not RAM fast.

Any G5 is going to womp that P4 in video simply because of the software. You would be doing your school a huge favor by convincing them to get a Mac.

P-Worm i only sugested the dual g4, if there are budjet limits.

remember if software is written for dual processors like quake3 you will see that the p4 is only 20-30% faster then the bus limited g4's, if it is not the P4 is twice as fast and since most apple apps and macosx are MPaware,the G4's are viable candidates as a second choice to the G5.

in fact everything video done on the macs recently has been done on a g4.

it might even be faster at somethings then the single G5's, like it is at somethings against the P4.

again this is a good second choice to the superior G5, not a first choice, and it should give you a few years if and only if you cant afford the G5.

i would also make sure you tell them about apple winning the first ever technical grammy, for firewire and final cut pro. also mention its the number 1 video editing software being shipped. i would also get in contact with video editing houses in your area that use final cut pro and maybe get some info from them. being a salesman, basically you have to know what your talking about and apply to that the pc to make it sound crappy. say what the mac can do, then how the pc cant do it, or how it wont benefit the students. just dont go in there and say macs rule and pc' suck. sound smart, even if your not :)

As someone in the forum said, there's always going to be a faster computer in 6 months so trying to get the fastest computer will just be frustrating. The software is the important thing especially in a learning environment. On a Mac you can use Final Cut Pro or the AVID DV editing program -whatever they call it now. There is only AVID on Windows. They are playing a constant game of catch-up with each other but Final Cut is the program that is innovating and always scaleable for whatever format.

In the industry AVID still has the lead in number of systems and qualified users in use but Final Cut is leading among independent film / video makers. There is a resistance to change both because of the investment in equipment in place and just plain fear of new technology. High school and college students don't have that fear.

In the nineties, I gave AVID training in a program in New York to most of the editors in the Editor's Union here. You never saw so much fear in a room! The fear was both of AVID but also just of computers.

Some big editors had heard about another system, Lightworks, and were resisting AVID because they heard Lightworks was more 'film-like'. Well, Lightworks lasted another 2 years and there are still maybe 2 editors out there in LA using it but no one takes it seriously. One of its big drawbacks -being on a Windows platform.

Premiere just released a major upgrade -for Windows only. No one who makes a living working in film or TV takes Premiere seriously and probably never will.

I've used both AVID and Final Cut and prefer Final Cut. It is very powerful and very well geared to my way of work.

AVID can still do some things Final Cut can't -like multiple camera handling -but that's only the expensive AVIDs not the DV one that competes with Final Cut.

good well informed points hsilver.

For DV editing you want either FCP or Avid DV.

The one benefit of using AVID DV over FCP (each program has individual pros) is the in the professional market avid is still king.

If the concern is just DV editing then either choice is fine.
Integration with the DVD SP will make the whole DV experience friendlier

But if this is a learning experience as a stepping stone in to the professional world, learning the AVID workflow is very important, even more so than ease of use.
having experience in using an AVID DV will let you be able to sit down on any avid system and know how the basics of the program and its workflow that you cant just fake. this is important for anyone who will be trying to get a job in this field.

FCP is a great product, but unless you are working on ind. films, AVID is still holding on as the editing platform for professionals.
This is changing, but very slowly

Thanks for all your help guys. Few more questions:

Do you think FCP express would better suit a high school than FCP?

What is a "set top dvd player?"

What advantages does a 64 bit processor have over a 32 bit processor for DV editing?

What are some disadvantages of the dell machine?

FCP4 beats the pants of FCE. Besides, FCP4 for schools is only $400 (might be $300, I don't really remember). FCE is FCP3 with some mostly unnecessary stuff removed (except that you can't set in and out points while logging and capturing, which isn't so bad if you learn it with capture now anyway). FCP4 has some super-awesome new features. I've worked with DV editing on the high school, middle school, and commercial levels, and FCP4 is the best thing I've seen yet.

set top dvd box = a dvd player that you hook up to your tv $50 and up
some have progessive scan, mp3, vcd playback, componet out, many say when teamed up with a good display gives superior quality then dvd players in computers.
just set this box on your tv and play.

dell equals microsoft

=xp=bill gates
although the dell is good yes pcs arenot as bad as we mac zealots let on
however
i do believe the software/hardware by one company advantage of the powermac overshines it with better integration.

I don't think that is very relevant and, IMO, shouldn't be used as a decision maker. Knowing the Avid workflow is a bonus but it's not that important (and not very hard to get the basics down IMO). Avid and FCP have similar work flows so it's not difficult at all the pick up one if you know the other. It's not like they would be coming from Premiere or Vegas (which have very different work flows and interfaces) and then trying to hop onto an Avid or FCP. And FCP has much, much deeper penetration in the pro market than just indie films or people who just can't afford an Avid. Avids are being replaced by FCP rigs, IMO, at a fairly quick pace and I can only imagine what the editing landscape will look like in a few more years.

Also, when they get their first job it's almost a given that they won't even touch an NLE in the day to day work as a PA, runner and/or tape vault/dub room person. When their work calls for them to first use an NLE (probably to log/capture footage) they'll get trained on how to do it. Even if they know Avid they'll still have to get trained in regards to organizational workflow (put X clips here and Y clips there use these settings on this, use those settings on that, ect.,). I knew Avid, AE and PS coming outta school but that didn't help me a whole lot at my first job which involved routing decks (Beta, DigiBeta, 3/4", 1/2", 1", DAT...), making dubs and some, *gasp* linear editing. Now, my software knowledge probably woulda moved me outta the dubroom faster than average (assuming I stayed w/that company), but even if I didn't know anything about Avid or AE I woulda had plently of time to learn the programs after hours before I woulda even been considered for a promotion.

So, the point of my whole rant is that knowing how to use an Avid is definetly a bonus, but it won't get you a job right out of school and not knowing Avid won't cost you a jog right out of school. And if you get a job w/a place that has Avids you'll have plent of after hours time to learn how to use it before your boss would even consider moving you up to a position where you would need to know how to use an Avid (did that make sense?).

Well,,, I guess that's all for this rant. ;)

Tazo, have you been smoking something really?
No school will ever install like 8 gig of memory into a computer anyways, nor will they install even 4gigs. 512mbs-1gb is top for schools. So that is not an advantage by far.
And software is cheaper for mac? That really starts to crack me up. And not in all cases mac program are more efficient. I can tell you that 3Ghz P4 with Adobe Premier very likely will beat a mac that is 1.8Ghz and even possibly Dual at most tasks.
And don't forget, now schools often go mainstream, trying to consider that people will more likely to use pc in the future. 90's are gone, democrats are gone, government doesn't influence the decision as much these days.

It is also possible that because it is a school that they may already have Macs, and it will be easy to use old software on the new beast.

I agree that FCP is a great editing program, and will be a force to reckoned with. I still stand by an avid anyday. For the money, especially the AVID DV EXpress. (which has the color correction power from the AVID symphony). I've directed or produced over 25 television shows in Hollywood and have never seen any professional editor use FCP to cut the show. (ever). I agree and have seen editors in the indie world cut beautiful movies with ease using FCP, but it's rare & growing. If you want to be a professional editor, learn the AVID. If you want to keep up with the changing times, learn the avid & FCP. Eventualy they will be even. Good luck to you.

Just off the top of my head "Scrubs" is cut w/FCP, Walter Murch is cutting "Cold Mountain" on FCP, and I know more than one trailer house that is switching/has switched to FCP, at least for their off-line NLE's.

If you want to edit for a living learn to be a storyteller. Learning the tools of the trade is the easy part.

I agree with both Mr. Peach and LethalWolfe (especially Mr. Wolfe about what's important now verses later. (BTW, I'm starting to feel trapped in a Tarantino flick)).

However, to address one of your points, a Pentium 4 will encode much faster than a G4 dual. I have yet to see what a G5 can do with encoding, but the difference in encoding speed is phenominal between pretty much any Pentium 4 and a top o'line dual G4 (we're looking at a Pentium 4 2.4 needing about 1/3 to 1/5 the time to encode the same video as a dual G4; it's just that fast) At the studio that I work at, and it's primarily Macs (close to 90% and Steve Jobs drops by to give us more any chance he gets because he's hankering to use my boss in an Apple commercial as an endorsement), we keep Penitums around just for the encoding process. I can't imagine that a G5 will be able to beat a Pentium at encoding; the reason is very simple, the encoding process has been heavily optimized to take advantage of all parts of the Pentium 4 chip whereas, the G4 chip didn't have the right extensions (this may change in the future if new codecs are written to take advantage of G5/970 on chip units.. but you're still looking at quite a bit of time before that's ready)

As for software, FCP 4 is good. I, personally, favour Avid DV. Avid DV Pro + Mojo is not only more expensive than FCP 4 but it is quite a bit more powerful than FCP4 on a G5 in speed (You might as well start comparing the Nitrus system which is way more expensive); they aren't competing in any marketplace at the moment (especially since Mojo isn't even available yet).

FCP 4 is the new kid on the block that's making some headway into the video editing world (especially since it has a much lower price) but AVID is the king and much like it's audio counterpart (Digidesign and its ProTools, which is also part of Avid the company), I don't see them loosing much marketshare to the new kids, even if the new kids are more innovative. The work flow between the two systems are similar (Apple did learn from the marketleader, Avid, when developing FCP4 which is appropriate if you're trying to break into a dominated market), but Avid still has a modularity akin to older linear editing that seems more complimentary to film editing. I don't think it's a fear of moving to a new software platform that keeps FCP4 from taking a stronghold but that those used to Avid will find some features lacking in FCP4 that they have grown accustomed to. LeathalWolfe and others who are proponets of FCP4 will probably disagree with me, but that's just my take on the situation :rolleyes: :) .

I, also, believe Avid has education pricing and you can get Avid for both Mac and Intel (FCP 4, is Mac only, of course.) A turnkey (hardware plus software package) solution for either software may be your best bet for pricing (and at least you guarantee that it will be tuned for the purpose of video editing.) Contact either Apple or Avid (if either ends up the direction your choice and ask them about good turnkey solutions for the education market; they'll both be glad to help because they "want" tomorrow's video editors working on their systems and they should be able to provide you with third-party groups to customize within your price-range (plus they know their products best; just don't ask for any comparisons between the two because obviously anything you hear will need to be taken with huge heaping spoonfuls of salt.)

LethalWolfe
Sep 12, 2003, 09:00 PM
If money was no object I'd probably pick a hi-end Avid MC/FC setup over FCP 4 any day of the week. The non-DV Avid products are much more mature and refined systems (which they should be sense Avid has been in this game longer than Apple has). I'm not a huge fan of XDV just because all the XDV boxes I've cut on have felt very rough (maybe that's because they were all PC based?). But getting back to my point... but money usually is an object and 9 times outta 10 the things that an M/FC give you that FCP doesn't aren't worth the grand canyon sized price gap, IMO. I mean for 'round $15k you can get a basic FCP NLE that can handle HD. I don't think $15k can even get you an Avid that can handle SD can you? IIRC the MC adreline<sp?> will start around $25k.

Now, does FCP comapre to a DS or a Symphony? No, but it's not supposed to. The DS and Symphony are compositers/finishers where as FCP is an editor (like the MC and FC). And altough I think FCP gives the M/FC a run for their money I still think Avid comes out on top. But in a couple of years who knows.

Lethal

Yes, I am aware that ATA/150 (SA-ATA, or serial attached ATA) can more than handle DV at maximum output, but unfortunately it would be no match for an 8GB RAM cache that holds a huge chunk of the DV file.

Think about it.

SATA:150MBps (theortical)
RAM: DDR400 (400MHz) running off of an 800, 900 or 1000MHz bus. Thats a fill rate that reaches into the thousands of megabytes per second.

While I see where you are coming from and the fact that any 7200RPM SATA hard drive put into a G5 would work just fine, you must always look for the edge in all of this- and I definitely see a huge RAM cache as an edge over an expoentially slower mechanical hard drive

While I see where you are coming from and the fact that any 7200RPM SATA hard drive put into a G5 would work just fine, you must always look for the edge in all of this- and I definitely see a huge RAM cache as an edge over an expoentially slower mechanical hard drive

Here is where I'm confused. When I'm editing DV video in FCP I need that video to be played at a rate of 3.6MB/s. No faster, no slower. How is storing video in RAM better than storing it on a HDD when the HDD can play back the video at the 3.6MB/s rate that is required? Editing video is done in real time. It can't be edited any faster than real time. A large amount of RAM might help speed up rendering of FX but I'm not sure how much real world bennifit you'd see from it. FCP might feel snappier, but I don't know if the FX would render significantly faster.

Now, for something like After Effects 8 gigs of RAM would be great because you could do longer/better quality when using the RAM preview function.

There's another piont I wanted to make but I can't remember what it was 'cause it's like 2 am here... oh well... :o

for DV editing a ram drive has 0 benefits unless you are on a powerbook. a ram drive would save power since the HD could spin down (as long as nothing else has to access the HD as well)
you would however have to load all the footage you were working on into ram.
there isnt any practical reason to go thru this to work on DV footage with its low data rate.

for aftereffects, hey the more ram the happier i am :)
