    Fast effects not showing correctly on Youtube/Vimeo

    Posted by Jean-jacques Boug on December 15, 2011 at 9:04 pm

    I have 2 scene with quick flashes which are 1 frame long, every 3 frames, and in Vimeo/youtube half or 2/3 of the flashed are missing depending on the quality (720p is messing up a lot more than 240p)

    Here are the source details :

    1280×720 (1.0)- 59,94 FPS Progressive 48000 Hz Stereo

    Output :

    NTSC 1280×720 59,94 FPS Progressive AAC 192kbps 48000 Hz Stereo Widescreen 16:9 (tried with squared pixels)
    VBR 2 pass Targe 6 Max 10

    Here is the uploaded video (@ 1:36 and 2:07) :

    I had the same issue on another one in youtube, were it seems to be slightly laggy (@ the beginning) :

    I use Adobe Premiere Pro Premium Production CS5.5

    Thank you

    Additional info–

    Here is how the timeline looks like :

    This is an AE linked comp and I use the frame gaps as black flashes.
    I have done the same without AE linked comp and same result.

    I’m starting to think that Youtube/Vimeo cannot handle very fast motion effects ?

    Cheers

    Hi Jean-Jacques,

    I think the answer is actually that Youtube doesn’t support 60P. I believe it did at one time, but no longer does. The end result is that half the frames are thrown out, thus the “missing” frames issue you are having.

    My advice would be creating a new timeline at 29.97, then copy and paste your old timeline to this new one.

    You may have to do some clean up after that.

    Hello Vince,

    Thank you for your answer.
    Should I try to export my project to 29,97 first ?
    If not I will try to make another timeline

    Cheers

    Hi Jean-Jacques,

    Exporting to 30p from the current timeline would also throw out of the frames.

    Yes I just found out testing on a very short sequence. I will try the new sequence with 29,97 fps and let you know

    Cheers
