Framerate issues with videoblocks?
Posted by Jessica Beckham on April 4, 2013 at 7:30 amI’m doing quite basic stuff in AE. To make a shortcut to more nice stuff, I’ve considered a few of the templates from videoblocks. In their documentation they state that framerate conversion is not an issue. In my experience framerate conversion is ALWAYS an issue… Am I wrong? All my projects are 25 fps, and all the files on Videoblocks are 30 fps.
Thanks.

April 4, 2013 at 12:53 pmIf there is no audio then simply interpret the footage as 25fps. You do this in the Interpret Footage dialog window. You will have a lightly longer duration; with 5 additional frames for each second of the original video.

April 4, 2013 at 12:58 pmThanks for your input, Roland.
My experience is (mainly) with 30 -> 25 fps video sequences. Not with AE templates. Nevertheless my results and therefore my experince is… erm… bad! It seems that no matter what I do, there will always be small “jumps” in the video track.
But what you’re saying is, that video will be identical (viewing vise, not spec wise – as 30 fps changes in the specs!) and equally smooth etc!?
Thanks again.

April 4, 2013 at 2:10 pmHi Jessica, for video-only stuff, do as I had suggested in my earlier post. For templates, it’s best that you change each comp’s frame rate to 25fps. You don’t have to do so if there aren’t any imported non-25fps footage in those comps.
It’s obviously a lot easier to simply change all the comps – use the following Javascript to do this in one quick step – https://www.redefinery.com/ae/view.php?item=rd_CompSetter

April 4, 2013 at 2:45 pmYes, if you do as Roland suggested, your video won’t stutter…It’s relatively simple to understand. If you leave as 30fps, in a 25fps comp. It can only display 25f in every sec, so every 5frames it will skip one, hence the jump.
keep in mind that if it was the opposite, you can keep a 25fps clip in a 30fps comp, and turn on frame blending(AE will try to interpolate) to eliminate the jumps while maintaining the duration.
