Vegas Pro 22 Freezing/unresponsive

Robert-Byers wrote on 6/21/2025, 3:50 AM

I've used different versions of Vegas Pro for several years and have always had problems with the software freezing or locking up occasionally whenever I'm trying to edit videos, but I recently upgraded to Vegas Pro 22, and to some extent it has become completely unusable.

I'm trying to edit a 50 second long video for a youtube short, and every time I made a change, the program would lock up for 1 minute or longer. I suffered through it and got the video to a state where I'm ready to render it, but then I went to render the video, and it has been frozen for the past 30 minutes. I've restarted my computer and I'm seeing the same behavior. My computer is more than capable of handling this program, so I'm not sure where to start trying to fix this issue.

PC Specs:
CPU: AMD Ryzen 7 9800X3D
GPU: 5070 TI 16GB
1200W GPU
Latest Graphics drivers updated
Windows 11 Pro

Aside from Windows 11 having it's own bugs, I've had no performance issues with anything else. Vegas Pro just doesn't seem to be happy with editing or rendering videos. Any suggestions on where I can start trying to debug this?

One cause might be the media being used in the project. It would therefore be most helpful if you could provide a detailed MediaInfo (a free app) report and upload it to this forum thread. More about MediaInfo including a link to download/install the app is in the following forum post:

https://www.vegascreativesoftware.info/us/forum/faq-how-to-post-mediainfo-and-vegas-pro-file-properties--104561/

Also, please advise the capture device being used (e.g. camera details, phone details, etc).

I also second MediaInfo- there's another user here with a 5080 reporting sluggishness with 10-bit 422 media.

In addition could you try one of the benchmarks in my signature and see if there's a general slowness or of it's media specific?

For rendering did you try a GPU-enabled format like MagixAVC with NVENC? (But if the problem is VEGAS is slow to read the media it can't render any faster than it can read it).

For testing purposes, does checking "legacy AVC" decoding in preferences, file io help at all? That uses an older decoder which can work better with some media.

Does Twitch give any choice as to settings? Having a shorter GOP (1 second or even less) makes it easier for VEGAS to edit.

I also second MediaInfo- there's another user here with a 5080 reporting sluggishness with 10-bit 422 media.

In addition could you try one of the benchmarks in my signature and see if there's a general slowness or of it's media specific?

For rendering did you try a GPU-enabled format like MagixAVC with NVENC? (But if the problem is VEGAS is slow to read the media it can't render any faster than it can read it).

it seems like it is media-specific. I rendered the newer benchmark test and it hasn't had the same problem, whereas with my media mentioned above it wouldn't even let me open the Render As dialog.

Elapsed time for that benchmark is 5:45.62 using CPU only. and 2:03.12 with GPU acceleration.

Actually, yes. I checked legacy AVC, closed my project and reopened, and it was extremely fast after that. Vegas opened instantly instead of taking 1-2 minutes to display any media in the Project Media window, it let me open the Render As dialog and rendered in 32 seconds. Thank you!

As for Twitch settings, I think it's dictated by my settings in OBS when streaming. which the Video Encoder has an option for Nvidia NVENC H.264, but it was set to x264 during that stream.

Anyway, the legacy AVC option seems to have resolved the issue for now. Thank you both for all of the help.

@Robert-Byers Thanks for your testing and for reporting back.

It seems like there's an issue with the 5070 Ti as it really should be faster than this. I'd check back if there's another update to 22 or when 23 comes out and see if it performs better when legacy AVC is unchecked.

I also use the VP 20 benchmark to make sure everything is working on my system- it's helped me troubleshoot Windows issues in the past just knowing what my time should be.

For OBS, try 1s as the keyframe interval (so 1 keyframe every 60s instead of every 120s).
