DaVinci Resolve 16 can’t read AVCHD mts clips well

Resolve 16 can’t read AVCHD mts clips well
‘Hi there, I have been using FCPX and I am trying to transition to Resolve. I have Panasonic Cameras that shoot AVCHD. With FCPX I just connect the card to the MAC and “import to the project” and I get the clips I am expecting, but when I dumped the AVCHD folder on to the MAC and tried to read the mts clips I got bad playback issues. How can I import the AVCHD mts files to Resolve 16 successfully for a smooth workflow?’

AVCHD did work in Resolve but no longer does so properly. I have found that the AC3 audio causes stuttery playback with AVCHD. Remove the audio from the timeline and the picture will play normally.

For those that need to use AVCHD it looks like transcoding of files will be needed. Or possibly try an earlier version that had no problem with the AC3 audio.

To convert AVCHD MTS to ProRes 422, from “Profile” bar, choose ‘Apple ProRes 422 (*.mov)’ as output format under ‘Final Cut Pro’ column. The ProRes 422 is a good option for the .MTS files, and the file size is reasonable.
