  rendering fast forwarded video

  Posted by Veress Attila on October 20, 2009 at 6:40 pm

  Hi im started to render a footage on 4x speed, but it renders so damn slow. Any way to speed it up or any other methods to speed up a video that doesnt make it render for days(im using time stretch)?

  It depends entirely on your needs …

  What I mean is that AE often generates noticeably better quality results with playback rate adjusted footage, but it often does take significantly longer than doing the same in video editing software (i.e., FCP, Premiere, Vegas, etc.). So, if you’re footage is for 320×240 on YouTube, consider doing the time shift in your NLE, but if it’s for HD broadcast TV … well, I’m sure you get the idea.

  If you are going to do it in AE, you might test small segments of your footage using each of the 3 frame blending options (including off, as Dave suggests since blending is more useful for slo-mo) … depending on the particular footage, both the quality of the result and the render time can be significantly different so you might want to make sure the result will be acceptable before committing to what can be a very lengthy render.
