Pro Tools 8 and video playback in Windows

[djgizmo]

On windows vista trying to compose some music to a QuickTime video. On my pc (quad core) the session is choppy unless I close the video window itself. If. Take the exact same session and play it on a dualcore iMac at school the session plays fine.

QuickTime file plays fine in vlc or QuickTime 7.6.

Any suggestions?

Just lower the QuickTime priority in preferences,

cheers

[djgizmo]

I'll try that and report back

[djgizmo]

Well, I tried that (lowered the video priority), and now the issue is just been modified.

Playback isn't choppy, but the video is.

What gives?

how is the video encoded? h.264 is very processor heavy. you need a pretty fast PC to decode the video AND run the audio at the same time. Try a different codec.

[djgizmo]

Well, I opened a new session with a different video. and it seemed to move fine. wierd.

I opened the files in Gspot to find out what the difference between the files were and they are as follows.

Video that works fine
SVQ3 - Sorenson Video 3
Frame rate: 29.971
48op

Video that doesn't work fine.
Codec - avc1 - H.264
Frame Rate - 23.976
480p

Any idea why an H264 file won't play well on a pc vs a mac with the same software/hardware, but the mac has less cpu muscle. As I said, I've got a quad core pc, how much more of a beefy pc does one need?

[djgizmo]

bump, anyone?

[Fajita]

update quicktime on the PC?

[djgizmo]

yea, it's updated. I'll perform a full uninstall of it and reinstall and see if that works.

[djgizmo]

well, uninstalled and reinstalled quicktime, same issue. no better, no worse.

I didn't always have this issue. I know others have reported it for mac on the duc, but not for pc.

lol, I tried googling h264 Pro Tool Windows Vista 480p and I find this thread. Go figure.

Just convert it to another codec, H264 can cause heaps of issues.
Try a DV or Jpeg.

[Fajita]

Mjpeg-A is good for pc

[djgizmo]

What progs do you use to convert from H264 to Mpg / DV?

Quicktime Pro.

... or MPEG Streamclip... from Squared 5 - MPEG Streamclip video converter for Mac and Windows (freeware), does AVI and co. too.

[djgizmo]

Thanks Andrew. Mpeg Streamclip saved my bacon.

I even purchased QT Pro, but everytime I'd export to DV, I'd get a 4:3 video, even though I set it to use 16:9.

Good people like you make me feel glad I love post work.
