.mov playback in video editors sucks

[RoundPorch]

Acer Revo
Intel Atom 1.8Ghz
64bit Windows 7
nvidia ion graphics

I have h.264/aac .mov files in 720p from my helmet camera. I want to cut them into @1 minute clips and put a video together. Problem is any program that I use to open these files for cutting/editing won't playback smoothly, programs for playback only seem fine.

avidemux - audio and video is choppy
avisynth + virtualdub - Just shows a still frame while playing the audio
mpeg streamclip - the best out of anything, usable, but not normal playback
videopad editor - video is way behind audio in preview playback
adobe premiere - same thing, video skips to keep up to audio
vlc - playback is fine
classic media player - playback is fine

I installed k-lite codec pack, ffdshow, played with quicktime settings, read numerous posts about slow .movs but can't seem to solve it. This computer will playback 1080p movies with xbmc just fine.

Thanks,
Dustin

Why do you need smooth playback in the editor? Edit, save and play?

[RoundPorch]

It makes it much nicer for cutting. Also if for syncing audio to certain parts of the video it helps if you can preview what your doing without doing 10 final renders. I will do that if I have to but I would rather fix the preview playback if possible.

I see. Maybe try latest videoredo beta with mp4/mov h264 support. Free trial to test at least.

1) Upgrade your hardware. Just because it plays smoothly in a media player doesn't mean it will play ok in an editing application, the reason is the player is optimized for playback, the editor cannot use speedup tricks or drop frames . It requires indexing and frame accuracy (= slow) . Also most editors use software for decoding, but many players can use DXVA and offload onto the GPU for decoding.

2) You might get better performance re-wrapping into a different container e.g. mp4 using yamb, or .m2ts using tsmuxer. The reason is many editors use quicktime to decode and parse MOV wrapper, and its decoder is single threaded (or poorly multithreaded) on a PC. Not sure if your atom has more than 1 core, so this might not help you

acer revo = pc jr. not good enough for anything much more than net surfing and email.

Makes sense to me if it's a resource issue. I didn't realize the editors cannot use graphics hardware. I'll try re-wrapping, otherwise will just have to deal with the slowness until I can get a decent computer. Thanks for your time.
