Sony VENICE 2 X-OCN files are not supported in Catalyst (it doesn't matter if it is LT, ST or XT). Catalyst Browse will play the audio from these files only. The only viable alternative is Sony Raw viewer. This software will play the files...but without audio. So that makes reviewing selects for transcoding fun. Since the Venice 2 doesn't generate proxies (unlike every other Sony camera of the last 5 years - including the Burano with the same sensor), software to review & transcode becomes fairly necessary. Aside from the audio issue, Raw viewer has poor performance for Mac users - it's clearly not Apple Silicon native. Transcoding is slow. Gyro stabilization not possible.
