Rendered Video is Too Fast and Too Short

[Flashback]

Hi, when I render a clip with the Replay Editor the output video is twice as fast as it should be and ends too early. It's not always the case, but I can't pinpoint what's causing this. I hope someone can help me or at least tell me if they have this problem too...

Try using a different video codec. x264vfw, Lagarith or UTVideo are common options.
