I don’t get it. If you render, you render to a HQ file, that is probably NOT the same as you send out for approaval. If you must do a BITC (I would add a subtitle file with TC’s, so they can be turned off), why not do the BITC on the pass / transcode where you create the clips to send off?
I want to not have to render twice just to get the BITC. Seems like a subtitle file (if it can be generated out of AE when I render) would do the trick.
I am actually just sending HQ files for approval… but maybe an Adobe Media Encoder watch folder with a setting to burn in timecode could do the trick. That way I would have an HQ file AND a compressed version with timecode because yes ideally I would be sending smaller files for approval.
I don’t know anything about subtitle tracks, or getting Adobe Media Encoder to add TC.
