  • Time remapping drop frames etc

    Posted by Roger Burton on March 9, 2009 at 2:23 pm

    Hi chaps I have some mpeg 4 footage and am trying to remap it … I am finding strange problems, in one sequence there seem to be missing frames (when I arrow through every frame there are frame numbers missing), in another after a scene cut, one frame in and a frame from before the cut appears, in another the movement goes back one frame and then forward again. I thought this may be a field order issue but it only appears after time remapping any help please Regards Roger

    [Dave LaRonde] “If the footage you imported into AE is any kind of the following — Native HDV, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 — you need to convert it to a different codec. “

    the codec i would choose to convert it to is quicktime lossless animation codec. or, if you needed to save some drive space, and could handle a bit of loss (of course you’re already using mpeg4), quicktime photo-jpeg with a high quality compression setting (95-100) is very good.

    Thanks both, this project was handed off to me by a client so it’s a little difficult (he has had no problems)! if I open the mpeg 4s in Qtime their frame rate is not dead on 25 fps, more like 25.18, this is an issue I guess BUT BUT BUT I did a little more digging and found that some people were having problems with Quicktime caused by the “EyeTV MPEG Support component” in Library \ Quicktime – removingit seems to have helped … I think … I’ve only just dumped it so I have fingers very crossed. Thanks for taking the time and I’ll keep this updated in case it’s of some use to others. Regards Roger
