Hi everyone, I’ve been using Action! for gameplay recording on Windows 11 and overall the quality is great, but I’m running into an issue where longer recordings slowly develop audio/video sync problems. Short clips work perfectly, but once the recording goes beyond around 30–60 minutes, the audio starts lagging behind the video little by little. I’ve already tried changing FPS settings, lowering bitrate, recording to a separate SSD, and switching between hardware and software encoding, but the issue still happens occasionally. Has anyone found a reliable fix or certain settings that help prevent desync during long recordings?

I had a similar issue with long recordings. What helped me was making sure the audio sample rate in Windows matched the recording software (48 kHz in my case) and closing any unnecessary background apps before recording. It didn't eliminate the problem completely, but it made the audio sync much more stable. Hopefully there's a permanent fix in a future update.

I had this happen too with longer recordings. Matching the Windows audio sample rate with Action! helped quite a bit for me. I also noticed closing some background apps made the sync more stable, so maybe worth trying that.
