I just tried it and Resolve can convert the audio TC to file TC, but there’s a catch. If I record the video in .MP4 format, Resolve reads the audio tracks and converts the audio TC to file TC just fine. When I record the same way, but use AVCHD, Resolve can’t detect the audio tracks and therefore can’t convert the audio TC to file TC. However, Resolve won’t write the TC back to the original file. So, while Resolve can do the job of converting and using the audio tc internally, the Tentacle Timecode Tool is the only solution I have now for writing the data back to a copy of the original file.
