  • 25fps footage in a 30 fps comp

    we have been working with 25 fps footage placed in a 30 fps comp.

    Is this likely to cause any issues on playback ? it looks fine when rendered and played on a computer but id is possible that this might not always be the case.

    Also what is the best way to deal with this for future comps? I am right in thinking that if we interpret the footage to be 30fps it will be fine but play a little faster.

    thanks for your advice. I thought as much . especially having 25fps footage in a 30 fps comp.

    would interpreting the footage at 30 fps cause problems though ? wont it just play a bit more quickly ?
    in this case it wont really matter if it does.

    Yes, interpreting 25fps footage as 30fps will cause it to play faster. There should not be any technical problems, but it might create a perceptual issue depending on the nature of the footage. For example, increasing the frame rate might look odd if the clip includes people or high motion. For a low motion or establishing shot, though, it will probably look fine.

    Other options include repeating, blending, or interpolating new frames.
