Just bought a new Canon EOS R5. 8k and 4k normal video (IPB and ALL-I) works fine in Vegas Pro 18. But 8k RAW and any kind of C-log footage (8k or 4k) crashes Vegas (MP4 file). I can play back the footage in VLC player (albeit at a surprisingly slow frame rate). But when I import the media file into Vegas, and it sits in the media bin (although with a corrupted-looking thumbnail) and when I click on it or try to move it into the timeline, Vegas freezes and crashes without and error message. I haven't adjusted anything in the internal options in Vegas, and no plug-ins installed except the effects ones that come with Vegas, so I'm working in 'vanilla' mode here. Working on a powerful new computer here, specs below. Any help appreciated!
