Folks: From time to time I make videos and upload them to Youtube, and many of them end up with some weird horizontal interlacing or breakups or whatever you want to call it. I’m capturing AVI from a camera via Firewire, editing it in Adobe Premier Elements and exporting it to MPEG 2. The video looks bad even on my laptop, so it’s not something that’s happening in Youtube.
Well for one thing, your audio is only coming out my left speaker.
Regarding the video, your camera is set to record an interlaced stream. As your source isn’t interlaced, this sucks and you should use a progressive recording format if your camera supports it. Otherwise, deinterlace by bobbing (for a high motion video like this – ideally you’d use a motion-adaptive deinterlacer but adobe aren’t very clever and don’t include decent processing filters). That will give you double the framerate you expect, so halve the framerate by decimation. Voila.
