Hi. I've used OBS studio to record various events and much of the time it works pretty well. However I have two problems. Sometimes for whatever reason the preview screen turns black and it records blackness. This usually happens a good ways into a video. Second problem is that the videos come out quite large. I've tried to mess with frame rates and quality, but I'm wondering if someone here has come up with "small file size" settings optimized for UOR since it shouldn't demand too much. My work-around has been to record a huge file and then compress it in Handbrake. Does anyone have a set of "good" settings in OBS that they could share with me? You could even make an OBS video of simply tabbing through all your settings! Thanks! I thought about putting this in "other" however it is related to the UOR world as that is what I record with this software .
I have been using OBS to record some of the holiday events and it has been working surprisingly well. The file sizes are around 3.5 and 5.5 gigs per event. I am pretty lazy and just upload them to youtube as is then use the built in editor to trim. Are you clicking or tabbing out of the window while capturing? What type of source are you capturing from in OBS? Settings are below (anything not mentioned is default) Recording settings are set to Simple with a 1920 x 1080 Canvas and output size at 60fps Quality: Indistinguishable Quality, Large File Size Format: mkv Encoder: Hardware (NVENC) Setup the scene with a source as "window capture" with capture cursor on. Setup Razor window size is 1280 x 900 which is large enough without having too much of the black boxes at the corners. Expand the UO window to fill the monitor (mine is 1920 x 1080) Hit Record. Make sure no other windows are producing sound (other uo clients, chrome, firefox, etc) otherwise it will be mixxed in.
I guess I could put my settings here to help troubleshoot as well: I am using display capture with a cropped window. Video tab: Canvas is 1210x870 with 30 fps Output tab:
Hmm, I cant tell whats causing the issue for you. I use 1448x926 with 30fps, not that different from yours. Encoder x264 Quality balance 8 Max Bitrate 30000 Under advanced tab try using the multithreaded optimizations, set process priority class - High
I did read that running as administrator might help resolve these issues. I guess I should have tried that first. Will report back after some tests. It also looks like the file sizes just have to be large. I played with different settings in both OBS and Handbrake and the best visible quality for smallest file size seemed to be large OBS file, small-ish Handbrake file. I just assumed OBS is capturing at a fram erate that is many multiples of the UOR client frame rate and so there could be some reduction to save room. I guess that extra step is worth the space savings, which is similar to what you guys are doing since both of you process your files after OBS creates them (Header uses Youtube and Keza uses a video editor or some kind).
The large file size is the trade off between how much processing power you can throw at it in real time. Re-encoding 1080p video on the fly takes a substantial amount of cpu cycles. My machine is old enough it just can't do it in realtime and I have network bandwidth to spare so its youtubes problem
