So I have a interesting problem. I work with a lot of PC Game footage. Most of our staff captures using Nivida Shadowplay, and I have 0 issues. However one staffer uses OBS to capture, and even though I can get it into Premiere fine, My System chugs constantly. It takes 4 seconds for videos to start scrubbing, 4-8 seconds to jump the play head to another segment before i see anything in the preview window, It's nearly impossible for me to scrub through the footage in real time. This only happens with OBS footage captured by him. The annoying things is on my Bosses computers, the Footage work fine, scrubs in real time, no delays or performance issues. The work around for me is to re-export all the footage through Media Encoder, but it's time consuming. I have no idea why its doing this. the Codec info from the OBS files is below as well as my PC specs.
i read shadowplay was the workaround for OBS as it uses heavy interframe compression. maybe your boss has an Intel Quick-sync compatible processor which Premiere can leverage the h.264
acceleration. So you either need another computer with quicksync or transcode OBS to friendlier formats, maybe there's an intraframe constant framerate version its its settings?
