Question / Help Choppy frame rate in SONY Vegas

[Dibidoolandas]

I've found other people having similar issues, but haven't been able to find a great resolution.

I've recorded some videos with OBS and they videos themselves look good. However, when I bring them into Vegas to edit, the preview frame rate looks choppy, and this carries through to the render. I'm pretty sure this is actually an issue with Vegas, because when I bring the same files into After Effects, the frame rate is nice and smooth. However Vegas is much better for my editing setup/speed.

Another thing that's interesting is that the frame rate issue seems to be inconsistent. I have a link to a published video I did where the frame rate is very choppy in the first half (as you can see here) and then later seems to correct itself (here). These are the same video file, in the same Vegas project file.

I'll post the log for that session as it should apply to the last few videos I did. Is there a setting or codec I should be using in Vegas? I imagine I'm going to get yelled at for my extremely high recording bit rate, but I've been using OBS for a while now and never been happy with the recording quality/frame rate until I turned it up like this.

This seems like an OBS Classic log file, but you've posted this thread in the OBS Studio support forum. If you wait a bit, someone will move it to the appropriate area where it will hopefully get better visibility.

@dping, help me out?


Also, please don't truncate logs. Please always post the full log file, preferably as a link (gist, pastebin, hastebin, etc.) or as a file attachment to your post.

In Vegas you need to turn off the smart resample and resampling in general for every video clip you add. Right click each video clip and make sure its off. It really sucks and screws up progressive video horribly, its intended for interlaced camcorder video, not video game recordings or anything using progressive scan.

Why are you downscaling to 720p with OBS, by the way? You're better off keeping it as 1080p video and downscaling with Vegas, or even later in the process than that.

I posted a better workflow for editing OBS recordings in Vegas, here: https://obsproject.com/forum/thread...lity-local-recordings.12600/page-4#post-48617 Also check out the video linked there.

You should feel free to use NVEnc instead of x264, too. Set your bitrate and buffer to 30000 each and your preset to HQ, change framerate to 60 and keyframe interval to auto, if you do this.

Hey, thanks for taking the time to respond to my question.

I've re-rendered that DOOM video, disabling resampling on all clips. Unfortunately, while the sort of blurriness between frames seems like it might have improved, the frame rate itself looks essentially the same, with the first half of the video being fairly hitchy and the second half still being smooth. Again I think this has to be related to Vegas, because when I bring these clips into After Effects they play just fine, but not sure what the exact issue would be.
