Because of the Corona situation, we got quite a few new clients, needing their events to be streamed instead of people attending physically at the venues.
One of the jobs was a conference with 3 parallel "tracks", so with a few hours of notice, we had to set up 3 complete production kits.
As we only have 2 vMix licensens and the economy is totally out of control for the moment, I tried OBS for the 3rd kit.
I'm really surprised to see how much of a performance difference there is between the two solutions.
Not talking about features but performance / quality of output.
We used the same "everything" for the 3 setups. Same cameras, same streaming platform (Vimeo), same bitrate / fps / resolution, same split screen (fullscreen PowerPoint + camera PIP i lower thirds) etc. but the OBS output is noticeably lower quality.
It's like the video is a bit choppy and 25fps even though we did set it up for 25fps. Also, the recording is lower quality.
I know this is a vMix forum, but is this something we should expect or should OBS churn out the same quality as vMix as things equal?
