    Hi there. When I import media via “link to AMA file”, my video comes in 31 frames out of sync. Footage is 1080p24 Pro Res 422 (HQ) and the QT files when played in QT are definitely in sync. The clip in the timeline reads 23.99. Project is set to 1080p24, RGB709, 1920×1080. Audio is set to 48K. I even tried a 1080p23.98 project and a 1080p30 to no avail. Is there a MC setting i need to change? Is there a pulldown being applied by MC? If so, how do I compensate for that? Just for kicks, I brought in XDCam EX footage into the same project (as that was all I could find at the moment) and that played back correctly. Any help would be greatly appreciated.

    Thanks

    Is the source clip 23.976 or 24? You want to bring the clip into a project with matching frame rate. Does the source clip have audio, or are you syncing with another file once imported? If separate, what are the settings set to for audio import?

    Do you get the same results if not using AMA and just importing directly?

    Is 31 frame calculate out to being .1% of total duration of clip?

    Hi Michael-

    Source clip is 24 frames with 4 embedded audio tracks at 48K, 24 bit-integer. So no syncing involved. Interestingly enough, I realized the project audio was set to 16 bit. When I changed it to 24 Bit all but 2 clips were in sync via AMA. Not sure why that is.

    One of the out of sync AMA files I imported at DNxHD115 and it is in sync, so the results are not the same. The clip works for direct import and not AMA

    The 31 frames does not equal .1% times the duration of the clip.

    Although we seem to have found a solution to that particualr clip, any thoughts as to why some playback fine with AMA, while the ones that don’t, only playback fine on direct import?

    Thanks for your assistance.
