Hey you rockstars at Magix, I have an error happening in Vegas Pro 19 on Windows 11 64bit machine. Vegas doesn't support Canons high bitrate ALL-I footage. To be fair, ALL-I 24fps is fine but 1920x1080 60fps ALL-I causes the program to glitch, drop frames and black out the footage. I put this same footage in Premier Pro and it had zero issues. Also, even Windows plays the footage back just fine. I suspect that it has something to do with the memory. I've noticed less blackouts and glitching (less but still present) the more virtual memory I add under the video tab in preferences. This problem ONLY occurs for ALL-I 1920x1080 60fps footage. Again, the ALL-I 4K 24fps footage is fine ... which is WEIRD! lol Any ideas?

@kamhunt Could you upload a sample clip for us to test in house?

Give me just a sec

So my workflow is this: I take a 60fps piece of footage and put it on a 24fps timeline. Then right click the footage to conform to the timeline. The footage then ends up being smooth slow motion, of course. Not with this particular footage. The lower bitrate versions of this same footage (1920x1080 60fps) works fine but this higher bitrate ALL-I footage starts intermittently glitching. That's not good. Ha

@kamhunt: Could you upload the original All-I footage onto a sharing website (like Google Drive or Dropbox)? I am assuming the clip you uploaded into your post is transcoded. We would need to look at the original footage to figure out what is going on.

@kamhunt: Thanks for the original footage. We are able to reproduce the problem using various hardware decoders (some more than others), but not with the software decoder. While we try and figure out a fix ASAP, you may want to turn off hardware decoding for the time being (Preferences -> File I/O -> "Hardware Decoder To Use")

Well that cleared it completely
