There is a distorted effect happening on this video that shouldn't be happening. If you watch the wood grain on the table it moves without that ever happening in the original footage.
I have rendered clips sped up before without this happening. Anybody have any idea what's going on?
We are not sure what's happening because the video clip is no longer available. My guess is that you may have some kind of moire visual artifacts occurring from what you've described. I would add a bit of blur to the clip to see if you get some improvement. See if that works for you.
Please let us know what is happening with this situation.
