So I recorded two videos today of me playing a horror game for my YouTube. Unfortunately, streamlabs obs loves changing my settings without letting me know. I recorded at 3840x1080 but like I said, obs changed my output to 1920x1080. So I have scrunched videos. How do I change them to 3840 in Pr.. so I can edit my facecam and gameplay separately..
If your original play setting was 3840x1080 but when recorded was squeezed to 1920x1080 (so everything looks tall) then when you drop your 1920x1080 footage into your Premiere Pro sequence set to 3840x1080 - then you need to go to the 'scale' parameters in your 'effects controls' panel - twirl open the scale setting (just under position) - uncheck 'uniform scale' - then adjust the 'scale width' to stretch your footage back out to to fit the screen.
Also depending if your footage was 'flagged' as 'anamorphic while recording there may be a simpler solution. In your timeline right click the problem clip and select 'set to frame size' in the popup menu.
