Black flickering occurs during both playback and rendered video

Bolla wrote on 7/28/2019, 3:59 PM

Hi!

I'm new to Vegas Pro, I recently switched from Final Cut Pro x to Vegas Pro 16. I make gaming videos for Youtube, and I was going to edit a video on vegas pro 16 for the first time, but everytime i looked at the preiview, it began to flicker black and it began to replay some clips, this all happened when i ungrouped the audio from the video (Because the audio was out of sync) but the preview still flickered black, but instead of replaying clips, the footage just became glitchy. GPU acceleration is off and i've desabled resample, how can i fix this problem?

Strange fps of your video sources.

What is the MediaInfo of the used sourcefiles and look also at this advice.

What is your used rendertemplate with the problems?

I'd say that frame rate of 48,000 in your project settings has something to do with it.

If you are doing youtube gaming videos, youtube maxes out at 60fps. So, you should not be capturing, editing, or rendering your video at anything other than 60fps (or 59.94fps). Might want to bump the resolution up to 1080p as well (1920x1080), as most games these days run at least 1080p resolution.

Ok thanks, I'll try. The reason the project i in 720p48 is because my pc isn't powerful enough to record in 1080p, and i recorded in 48 fps because everytime i record in 50 or 60 fps, obs crashes when i stop recording

What are you recording your video with?

Shadowplay does not work, OBS does work in Vegas.

https://www.vegascreativesoftware.info/us/forum/faq-what-obs-studio-settings-work-well-with-vegas-pro--109925/

48,000 means 48 fps in European.

j-v, I clicked the links but I still don't understand what I'm supposed to do, I read everything and watched the video tutorial. How is MediaInfo supposed to help? do I have to edit everything all over again? Are there any other solutions?

Sorry but if you are not getting what those faqs ask you to do to get help, I cannot help you anymore.

Mediainfo provides you with a detailed list of exactly what type of media you are using, which after posting it here, enables us to spot any issues that might be causing your incompatibility. You won't have to edit the video over again, at the worst you might have to convert it to another format before editing.

What are your system specs? I might be able to recommend some setting changes that will get OBS working better for you.

i recorded with the wrong encoder (NvENC) so instead of editing everything all over again, I'm going to export the video as a Final Cut Pro X Project (Because I have an old mac with FCPX) and send the project file to my mac, open it with final cut pro and export the video as a video file.

You probably just need to do the following.

https://www.vegascreativesoftware.info/us/forum/avc-xavc-s-issues-in-vp15-16-try-disabling-so4compoundplug-dll--108345/

it's a known problem with hardware encoding with nvenc OBS. Also there are 2 nvenc options in OBS, nvenc, and nvenc(new) . you could try the one you're not using now. I don't know what your cpu is, but maybe you are better off with nvenc rather than software encode for games.
