It comes with many merits: we don’t need to install drivers, and also even a Chromebook can record videos through it. If the format was independent from the issue, how about devices or applications which the video came from? “Ah, I might have realized a possibility.”įor the sake of simplicity, our whole video system which includes four cameras and a switcher is designed to be recognized as an integrated web camera through USB 3.0. But, unfortunately, it wasn’t the solution. So I converted my problematic MP4 files into MOV by FFMPEG command with audio re-encoding. It seemed that MOV file worked fine at least, but I’m not sure though.

MP4: some files work fine, but some others not. To clarify this issue, I tried the same with other video sources: “OK, I will solve it by myself.” I made up my mind.

Then, I googled the solution through the internet, but I couldn’t find any hints. I lost audio in every video format while exporting.

But, exporting as MP4 or MOV or other formats affected nothing. “It might depend on the file format?” I guessed. Only when exported from Resolve, it will happen. In a preview, it was fine, and of course, the original MP4 file included audio data as well. The video file exported from Resolve had no audio data except for the first 30 seconds.
