Question / Help Audio Offset not Applied??

[w0ek4kc39]

Hi,

I'm using OBS on a Dell machine and recording audio through the aux channel. Because I'm recording video separately through a 30 ft HDMI cable, the video is habitually about 200 ms behind the audio. I've tried solving this using the audio offset control under Advanced Audio Properties, which is the only way I can find to do it; however, no matter how much I set the offset to, the settings are not applied even after restarting the entire system. I feel like this happens because the Aux input channel is shown as active in the status column, but I can find no way to deactivate it to change settings. Thanks for all your help with this!

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...

Yes, I intend to add a log file as soon as I can get to where the computer is, which is difficult considering our situation right now. Thanks for waiting a bit.

Do be aware that offsets are only going to be reflected on an outgoing livestream, or the playback of a recorded video file. It will not alter the offset through the monitoring system, and the movement of the bars in the mixer will also not reflect the offset with any kind of delay. You can test this by setting an audio source's delay to 5000ms in Advanced Audio Properties and then recording a video, which will upon playback cause the audio to occur 5 seconds late in the video.
Audio delay is NOT reflected in realtime and will still appear to be 'off', aside from the actual streamed output or recorded video playback. Just to be clear. :)

Ah, ok. That should clear everything up for me. Thanks so much for the info!

No problem, it got me too when I was starting out. :) One good way to dial it in is to do a short recording, and clap loudly. Makes it easy to take the video into an editor and count the number of frames between the visual clap, and the audio spike. Then you just multiply by 16.5ms for a 60fps recording, or 33ms for a 30fps recording, and boom, you know how much to input as the delay (barring latency fluctuations and audio buffering from the sound device).
