Audio TC is absolutely critical to the eventual sound conform and mix. Even when synced, sound and picture TC will drift by a frame or two. You can never just use video TC.
I’ve gotten Resolve dailies from professional labs. I know there is some kind of workaround to get the sound TC metadata in the Avid MXF/AAF/XML. I’ve seen it written to an AUX TC and that can be duplicated into the “Sound TC” column and therefor the EDL to sound will be spot on.
I can see the AUDIO TC in the Resolve burins so the information is there.
Thanks
