Webcam and voice audio out of sync

Tue Jan 19, 2021 10:10 pm

Dear Bandicam,

I have a very old Creative Live Cam Optia with a resolution of 640x480 @ 30fps, that I record to a separate file. I record everything else at 60 fps. There consequently seem to be around 30-45 frames of de-sync between the voice audio and the webcam recording. It was my understanding that Bandicam should sync up the webcam and game/voice audio up nicely, but this doesn't seem to be the case. I don't seem to recall having this problem before even with this old webcam, be I will also admit that it has been a while since I last recording with a webcam overlay.

It is not a huge problem to sync up the webcam with the rest of the audio in post, but I am just asking to know whether this is a bug or a consequence of recording at different fps, using a antiquated usb webcam or maybe even something else.

My specs are:
Intel i7 8700 @ 3.2 GHz
32 GB ram
Asus Cerberus GTX 1070 Ti 8GB
Recording to a dedicated 7200 rpm hdd
Using Bandicam version 5.0.0 1796 (Because of sample rate issues with 1799)

Sincerely,
Michael Hansen

Unfortunately, it just wont help. As soon as you put Webcam recording as a separate file - the sound is out of sync. Please, Bandicam, there are hundreds of posts like this on this forum. Please fix it!

If the above does not solve the audio sync problem, please record your Bandicam and Windows sound settings, and then send the video file to bandicam@bandicam.com
Thank you.

On Win7, it's under Control Panel->Hardware & Sound->Manage Audio Devices->Recording. There, select your microphone, then Properties->Advanced. There you can change the sampling rate. If changing the sampling rate doesn't help, then you can only try another webcam software, or record the audio independently.
