  • Unable to open project from 15 to 20

    Hello, I just upgraded to Vegas 20, however the program will not open while loading projects from 15. Any thoughts?

    Could have something to do with the project contents or maybe some deprecated features. Hard to guess without an error message or more context. Is it one project or all projects?

    I have a couple of ideas in mind:

    1) Enable all deprecated features in Vegas Pro 20. Options -> Preferences -> Deprecated Features
    If you used .mkv files – that’s in the File I/O tab.

    2) Rename the folder(s) where your project assets are located in and try to open the project with all of the files in offline mode. Then it will be clear that the issue lies there

    3) Have you tried to drag the project file in the timeline of a new Vegas Pro 20 project? Doubt this will have any effect, but I’m curious if anything different will happen – maybe an error message?

    4) If you have the old version still installed – you could try and open your project in there. Select all, copy everything and then paste it in a new, blank project in Vegas Pro 20.

    Thanks Aivis, I tried all of these except renaming the files and once I introduce the 15 files to 20, it immediately shuts down. I can continue editing in 15, but here was my issue and why I upgraded…when I render in 15 the rendered video has intermittent times when it briefly speeds up, giving me a bit of a Charlie Chaplin effect. Have you ever seen that?

    This isn’t the first time I hear of such an issue, but I’ve yet to encounter or replicate it myself. My assumption has always been that it’s due to partly corrupt video footage (or just odd format footage) where it might have variable frame rate when it wasn’t intended.

    Possible solution in that case would be to convert that footage to basically anything else. A good tool for that would be Handbrake and there’s plenty of guides for it, just make sure to convert to constant framerate. That’s my best guess.

    Another option would be that there’s some driver/gpu/rendering problem. I think it’s less likely, but possible, I suppose. So updating drivers, reinstalling software, restarting pc – all potential fixes there. Another thing to consider might be disabling GPU acceleration in Options -> Preferences -> Video -> GPU acceleration of video processing. Setting that to off – if that changes anything, then it could be an indicator that it’s a GPU problem (+make sure not to render with NV encoder in that test case).

    Also – if you were to re-render the same footage, but in different context in a project – would the speed-ups be consistent or random? If they’re consistent I’m again further leaning into the idea that it’s a problem with how Vegas interprets that specific footage format.
