Quicktime 7 Sample movies?

Hmm, funny, that woule make those technologies like Blu-Ray and HD-DVD a bit redundant, since h.264 will make today's DVD seem like a HD-DVD. :)

you're both missing the point; we want to not only see how pristine it looks, we also want to see how good it looks at lower bitrate. And by "we", i mean at least me, maybe others.

and how does h.264 make hd-dvd/bluray redundant? now you can have extreme bitrates that you can't just yet with today's optical media.. it won't make today's dvd's look like hd-dvd since when they'll likely require new players for the new codec (and those new players will support the larger capacity dvd's at the same time).

hmm yeah.. that's much better :-\ am i missing the codec or something?

EDIT: i don't think i am, i verified the codec is in my /sys/lib/qt folder

Video file worked for me.

when i let the finder extract the tarball, it works.. when i extract it on the command line, it doesn't work..

guess the bomarchivehelper treats it differently? i thought they fixed /usr/bin/tar to handle resource forks? arg

FWIW its relatively the same bitrate as the 'Large' Sin City Trailer2

don't think your link works

you have to mirror the tarball file instead because it preserves the resource fork.. the bare .mov file will be useless..

on a side note, anyone know why ? i thought we'd be moving away from dependance on this type of metadate

any tiger owners wanna tell me if you can export H.264 via iMovie?
Click to expand...

i am exporting some dv from my mini-dv cam (25Mbit/s) to H.264.. it's only a 20 second clip but it's taking forever.. been at it for a half hour already (but i have an iChat video session going on also and that's going extremely choppy).

UPDATE: it was my ichat session that was slowing it way down.. guess using h.264 in the ichat didn't help heh..

question, is there an de-interlace filter or something? my dv stream is interlaced and it doesn't look too nice interlaced in h.264 :-\
 
The video source is uncompressed 1920x1080 @ 24 frames per second. True HD at full color resolution as well.

Here's a H.264 encoded movie I quickly made to test the codec. The file is a 7 second Jessica Alba montage encoded to H.264 at 5 Mbit/s, which falls within MPEG2 bitrates of between 4 - 8 Mbits/s. There's no audio.

alba_hd.mov (no sound) Option-click to save to your desktop first.

Be warned. You'll need a dual G5 and QT7 to play this puppy.

This video file is 4.9 MB, 7 seconds long. I will have to remove it if my bandwidth gets shot to hell.
 
Here are some samples

The good news is I posted some HD videos in H264. Unfortunately the fat angle is correct, most folks do not have access to high quality uncompressed video, HD video or film stock. I do so I will post a couple of short clips. Remember I haven’t received my copy of Tiger yet so I haven’t verified my files. Please give some feedback. You will probably need a G5 to play these back. They are 720P which is 1280 X 720 pixels. It usually helps to not use scaling in QT. In other words, if your monitor resolutions is 1280X 720 or above you should play at “normal” size.

As far as the comment on ripping DVDs etc. Remember no matter how good H264 is it can’t make the file look better than the source footage. Therefore the only reason to compress a DV stream is to have smaller file size.

These are the only clips I have on my home computer. I’ll post a couple more clips Tuesday from work where I have a lot more material. I’ll do one from 35mm film stock and one from 720P HD shoot with a VariCam.

The Varicam is the state-of-the-art HD camera for 720P HD. About $90K fully decked out. 720P is much better suited for playback on a computer than 1080i because computer monitors are only progressive and exaggerate interlacing artifacts.

Three shoots for now.

1st A shot of my dog at 30fps, shot with a varicam in 720P.


2nd A composite of a still shot take with a Nikon still camera and motion and text added in After Effects rendered out in 720P

3rd 30fps varicam shot of an auctioneer.

Links These will probably try to load in your browser, let them load then save the file to your desktop and then play in the QT player.

Hey, those are nice clips! I love the mastiff.mp4 the best. You have a good eye for the lighting!

When you mentioned 720P uncompressed footage, I was thinking you were shooting with a Viper Filmstream camera. I wouldn't qualify DVCPRO HD as exactly uncompressed, since it uses the exact same DCT-based compression scheme that DV uses.

The mark.mp4 clip was nice, you don't notice any compression artifacts. H.264 is da bomb!

man you people aren't kidding when you say it's CPU intensive.. my powerbook g4 1.5ghz w/ 1 gig of ram can't get over 10fps on that auct.mp4 :-\ the guy starts speaking, the a/v is desync'd, finally the video freezes (the audio keeps going).. is that normal? I can get the mastiff to go up to 20fps, what is it about the auction one that's so different? if anything mastiff is at a higher bitrate..

UPDATE: i think it's the fact that the auction has audio, the system is competing to decode the video vs the audio (and the audio seems to win).
 
Formats and data rate

Lacero you are right about DVCProHD being compressed. All tapebased systems even D5 are compressed. However, they are production quality compression schemes. DVDCProHD is the best for portable tape. It's color space is 4.4.2 where as DV is 4.1.1. This means you much more color saturation and can composite with out artifacts and loss of color. When I said uncompressed I meant some of the footage. For instance the marks.mp4 file would be considered and uncompressed file. Today I will create a file from a 35mm film project I'm working on. The film was scanned as 2k cineon files. It will have a little bit of grain however because it is film. Also, I have some animations that were rendered out as uncompressed targa sequences.

The three files I already posted were compressed at slightly different data rates. If you have QT pro look at "Get Movie properties" and check the rates. Let me know the rate of the one that plays back the best?

Also, how do you guys have Tiger yet? Let me in on how to get it.

I look forward to seeing more samples, here is the info from the ones you posted. They all play back choppy so i can't really judge which is "best".

Film footage to H264

Here is a clip I made from 35mm film footage. It was scanned with a film scanner at 2k resolution. I scaled it down to 720X1280 in After Effects to an uncompressed file and then encoded that file into H264 with Sorenson Squeeze. I'll post some animation Wed.

Thanks for some of these example clips! It really is amazing and most of the clips ran smooth and incredible looking even on my 933 mhz iBook :D

Apple knows a good thing when they see it.
 
Hmm...my powerbook cant seem to run them all constantly...They run for the first few seconds and then BOOM, i get a still...sadness.

same thing here.. i guess i need a cheap ibook instead of my 1.5ghz 1gb ram powerbook :-\
