Conform ProRes file to QT file
I am recutting a fully mastered show which is to be authored on SD-DVD. The show was previously transferred to BetacamSP and, from that tape, a QT file was created with window-burn TC (see specs below). I only have the QT-window burn file at this point. A higher quality ProRes 422 file (without WB) will be delivered at a later date.
My question is: if I do an offline edit using the low-rez QT file, will I be able to re-ingest/conform it to the ProRes file using Media Manager?
The video specs for the QT file are as follows:

Not unless the QT file has proper timecode. No, I don’t believe you’ll be able to conform it to the ProRes capture.
You’ll have to manually re-cut the project.

If your QT doesn’t have embedded timecode you might be able to use Bouke Vahl’s free app to add or set the file’s timecode to match the burned code. If your ProRes file to come has the same code you might be able to reconnect successfully. Maybe Bouke will see this thread and chime in, or you can contact him thru his site.

Someone suggested this work-around:
Open the clip in the Viewer
Modify Tab click Timecode
Add Aux TC 1
Export QT MovieI just tried this and opened the new file in Quicktime and, indeed, there was now an Aux TC (which matches the window-burn TC).
Will this allow me to now conform the higher resolution file to my offline edit?

Follow up to my previous post:
I changed the “source TC”, not Aux TC.
However, another problem is that, while the source TC in the browser now reflects the modified TC, the Timeline TC starts at 1:00:00:00 and I can’t get it to show the new source TC. -
All the above could work but depending on the length of your cut I usually find it easier to online manually by eye. Once you online by media managing / reconnecting media, you have to go through and watch VERY carefully all the mistakes that are bound to crop up. Usually I can overcut faster knowing I’m making the correct cuts rather than leaving it to chance and then fixing all the mistakes.
Best,
Joey
