If the sequence originated in FCP X, I run into the same issue, but if I import the footage directly into Resolve or Premiere and rebuild the edit natively in those apps it’s fine.
I learned that FCP X has issues reading Sony Alpha cameras timecode. Apparently it’s a known issue and only appears when you import xml sequences from FCP X that contain Sony Alpha Camera footage. If they are imported and edited directly in Premiere or Resolve from the start, there is no issue as these applications have no issues with reading the Sony Alpha footage.
There are two workarounds from what I hear and have confirmed they work…
1. Once the XML is imported into Resolve, go to each clip and change the Timecode start time for each clip to 00:00:00:00 in Clip Attributes. Not too big of a deal if you’re working on a short form project. But for longer project I would go for the next option.
2. Transcode any Sony Alpha Footage in FCP X to ProRes before exporting the XML into Resolve.
Again this issue is ONLY present when exporting XML’s From FCP X with Sony Alpha camera footage and importing the XML into Resolve and is a issue with FCP X and Sony.
I usually edit directly with Davinci Resolve from the start but thought I would experiment with FCP X this time around which is why I’ve never run into this.
