IME, AE CS5.5 Renders Wrong TC Regardless of Comp Settings!!!! (30fps when comp is 24fps and with the wrong start time. Even if you enter correct start time in comp settings, it’s still the wrong frame rate TC when rendered). A huge problem for offline and manual round-trip work flows. Below is a painful but simple working solution. Maybe I can help save someone the headaches I went through to come up with this. COME ON ALREADY ADOBE!!!
In QT7 Pro = Open Original Clip and Read Start and End TC. Click on TC display at bottom left to select proper display mode.
In FCP Import and Select New Clip in Browser.
Modify Menu = Timecode
Enter start TC read from step 1.
Choose proper frame rate.
Choose proper Drop Frame setting. Columns separated by a : = Non-Drop (01:00:00:00), ; = Drop (01;00;00;00).
Click ok.
Verify start and end TC of AE render match original clip.
Anyone else have a better solution? Please chime in!
