I took a capture of and OpenGL game "Minecraft" (it saved in .avi), but when I import it into Premiere Elements the footage will go smoothly, then cut back multiple frames, then skip ahead resulting in unusable video. The same thing happens when I save the video.
I tried the same footage in other editors (Corel VS X2, Windows Live Movie), and it ran smoothly. I used PlayClaw to record.
If it helps the video was:
Res: 848 x 480
These types are codecs are generally incompatible with Premiere Elements -- particularly when they use non-traditional frame sizes and frame rates.
I would very much recommend that, if you've found an editor that work with it, you use that editor rather than try to make Premiere Elements do what it generally wont' do.
Download and install G-Spot, to see what CODEC (Compression) is being used.
That is likely the issue.
The odd Frame Size will make choosing a Project Preset difficult.
