Action! recording - playback stutters and speeds up

[Dewm]

PC specs:
Windows 7 Ultimate
i7 960 3.2 Ghz quad core
AMD 5870 1Gb
24GB ram



When I record a game, it runs smooth as butter 55-60+fps, and the capture software stays high fps as well. But then I go to watch the playback, and around 50% of the time it has spots in the video where it will stutter, freeze or even speed up the video...

Why?

Its very frustrating to record 20+ minutes of content, just to have to delete it because its stuttering super bad.


Thanks

Could you post a video sample of your issue? Do you record into AVI or MP4?

I record with MP4 @ 1080p

I worked on it for like 5 hours last night, and I THINK I found the issue. A little more testing today will confirm it.

But I was read/writing to the same HDD that I was playing the game on, and I think I was getting a bottleneck with the data transfer.
So I changed my "video dump file" to another hard drive, and so far the 1 recording I did went smoothly. I'll post back and let you know if it did fix the issue 100%

One thing I figured out is that if you leave the video as is you are going to see all kinds of stutter and the video quality will be much worse than the original. Export it to something like 1080p (High Profile) then upload it to Youtube; it will still lose quality (thanks, YT encoding!) and you might see a little bit of stutter, but not as bad as the original non-exported video. If you export it directly to Youtube HD is comes out pretty badly by comparison. I hope this gets fixed.

P.S. Would setting Action! to high priority or assigning it to just one core make any difference? I remember Fraps had to be set for just one core to fix the stutter issues.
