Streaming and Recording

Started my stream for a basketball game and during the pregame it was smooth and clear. Right at tip off I started to record on OBS to have a saved copy and it went super choppy. Audio was just fine. Both the recoding and stream were terrible after hitting record. First time I have tried to stream and record simultaneously. Any suggestions on what could be the issue ?

Start by following forum pinned posts on support requests

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

Beyond that, it depends. If your recording uses stream settings, and saving to a fast disk drive (SSD) then recording should be fine
BUT, it your system is close to maxed out with streaming, and you have some settings that cause extra work with recording, it woudl be easy to overwhelm system

Obvious HUGE issue in that log
18:55:45.125: Video stopped, number of skipped frames due to encoding lag: 209974/269156 (78.0%)

Sorry I'm unfamiliar with AMD encoders and whether the log indicates using GPU encode offload or just the CPU. Looks like trying to send to GPU... but not my area.

Should the recording be set the same as the stream? It streams fine using less than 10% of the CPU. I had it to record in mp4 format.

Search these forums to understand why ignoring the BIG RED text to not record in MP4 is a bad idea.
Should recording be same as stream? it depends on what you are trying to accomplish, and the resource(s) you have to pull that off.
*IF* you are resource constrained, then having Recording use same encoding as Stream will avoid extra work. I stream at 720p, but want a higher quality Recording at 1080p so I don't use the same, but I have spare resources so no issue in my use case

If you Stream only, and have no problems, then typically you should be able to Record using the same settings without an issue as well, as long as you aren't Disk I/O bound
