Hi All,
I'm now FINALLY using FCP 7 on my setup (check my sig) and I wanted to find out why is it not rendering at full speed? I get done with a sequence and then go to Sequence > Render > Both (to render both audio and video files). But unlike my single processor machine that is OC'd it would render my file at full tilt (iStat would report 600% to 700+%), the SR-2 is only rendering around 12% - 25%? Why? Is there something in the BIOS that I haven't checked off or is there something in the preferences in FCP 7 that I need to select to enable full speed rendering? Also, when I do see any type of rendering I only see 12 threads being used and not all 24. But even with 12 threads, this thing should be cookin' through these files... Whatever help you can give would be very helpful...
Well, after looking at my limitations with all these vid editing apps, I found this link to a 3 min vid on Adobe Premiere 6.0 (AP6) here:
http://www.adobe.com/products/premiere.html#nerolimedia_split_pp-chilipeppers_708x398-1300.mp4
I saw this vid and how this vid producer shared his jump from Avid to FCP and his disappointment with FCP (I'm sure he was talking about FCPX). He's now using AP6 and things just work. Well, I just tried it today as I have AP5 (not AP6 yet) and imported an .MTS file and it just works... So now I'm wondering if I should just stick with AP5 and upgrade to AP6 later on sometime. If there is anyone who can share more on this topic of their experience and what they think that would be great. Thanks for taking the time to read this post and look forward to your replies... Later...

Hey PunkNugs, what codec are you rendering to and what codec is your source media? Final Cut has always had a major preference for ProRes for obvious reasons. If you are using h.264 native Canon 5D material or XDCAM long GOP material maybe there's a bottleneck with the codec?
Also I don't think Final Cut 7 was ever 64bit, not sure what sort of impact this has though.
I have a bunch of different media on my machine at the moment, I might do some tests and see how the different codecs behave.
Ok I've done a bit of testing and research.
Final Cut Pro 7 was never built to fully utilise multiple cores and was a big sore point for the FCP community.
This is why I think they had to completely rebuild the app for Final Cut X. It seems the FCP 7 32bit limitation also limited the amount of RAM available to 4GB.
Now, my second finding, through practical tests is that use of multi-core rendering is very specific to the specific task within the app, not the app itself overall.
Rendering 5D h.264 media in a ProRes 422HQ sequence only saw FCP use 270-300% in the activity monitor.
GoPro AVC media in the same sequence was far less consistent, using anywhere between 150-290% and jumped around greatly.
Use of non-realtime effects like the Radial Blur (on ProRes media in a matched ProRes timeline) consitently stayed at about 230%.
Note that I barely saw the total user% of CPU power break 10%...
I think the processor use varies depending on the effect used, I'm not going to test all of them though!
I did enable Apple Qmaster, which is designed for multiprocessor distribution in Compressor. I did see process instances appear in the Activity Monitor, however they didn't seem to be doing any work for Final Cut. I think it's built for Compressor only.
Now just for comparison I did some tests in Avid Media Composer 6.
Importing 5D media to DNX HD 185 MXF format still only used about 130%.
Radial Blur only used 120%
3D Ball used ~300%
HOWEVER
Scaling a clip with 3D Warp - 1700%+
Rendering a colour correction with the hue wheels - 1700%+
Safe colour limiter - 600-1300%
These last three tests were using up to 80% of the total user CPU%.
Now when you stack a Radial Blur on top of a Colour correction and Safe Colour Limit effect, it processes the entire clip at the speed of the slowest effect.
So now we can see, even in an app which is designed for multi-processors, there are still limitations depending on the tasks!
PunkNugget said:I can only tell you I never had rendering issues with my Gigabyte UD7 mobo and W3680 using FCP 7. A ten min. vid would take no more than 15 min to render, sometimes even less. Now the same exact file that I transferred to test on my SR-2 system is now taking 7 to 8 hours. I had to stop the test after 1/2 hour; thinking that it wasn't going to take that long and that it would have been done within 10 min at least. Well, it wasn't and I was only 3% into my rendering the 10 min file.
I'm importing .MTS to .MOV - now FCP7 won't do it anymore on my SR-2, but still will on my UD7 setup. Now I use a conversion app to make that happen to convert it to a .MOV file so I can import it into FCP7 and it works finally. But again, I want to use my SR-2/2 x X5690 setup and not my UD7/W3680 setup
DJenkins said:Your problem is a bit different to what I went through in my reply, but my best recommendation would be to find an encoding program that you know uses all your processors, then encode there before editing. That way you're footage matches your sequence settings, FCP loves this.
I'm moving more into shorter form motion graphics so long imports and transcodes of video media are getting fewer and fewer for me these days. So I'm not sure which app handles this best, sorry!
It is very strange how you are getting vastly different results between two hack machines though!!!
My tests are done on an Sr-2 with X5679 CPUs @ stock 3.2GHz
I hope my info helps, let me know how you go!
Best regards,
Danny
PunkNugget said:Let me know what you can about some kind of encoding app that can work with FCP7 or Avid Media Composer 6 (or 6.5). I just purchased AMC 6 and I'm having issues with just the video NOT playing after importing. Here's the link to what I posted so you can read it:
Now this is using AMC 6.0.1, 6.0.3
http://community.avid.com/forums/t/113440.aspx
Now with AMC 6.5 this is happening:

but then after googling the actual statement I found this link on Avid's forum site:
http://community.avid.com/forums/t/64626.aspx?PageIndex=1
Seems that this has been an issue since 2008 to present day. I'm upset because I tried the trial and the video was playing the .MTS files directly from my Canon Vixia HFS-100 natively with no importing and now when I purchase the actual copy it DOES NOT PLAY AT ALL; even when I install the specific Canon plugin that makes the video show up in the bin so recognized by the system.
This is another form of frustration. I look forward to any help at all as I'm needing to produce more vids here in the next week and don't know what to do. Thanks...
