Glitch in 1st second of audio track of exported video

Help/How To
1

Hello,

I just rendered a video, like I’ve done dozens of times before, but noticed a small distorted glitch in the audio during the first second of audio.

So I tried picking a different audio codec to make the video with. But none have worked. I tried ALAC, FLAC, PCM_dvd. I get either a failure to export; the same glitch, or a silent movie with no audio. The default one (AAC) is the one where there’s a weird glitch.

Any suggestions?

Maybe the glitch is caused by your source video file. Shotcut requires accurate seeking to get good result. But some files are difficult for Shotcut to seek. For example, VFR files can cause the problem you describe. Also, some containers (like TS) are not easily seekable.

As a test, you could try to convert the video file that is at the beginning of your project. Export with the converted file and see if the glitch is solved.

Other remedies may include editing out the first second or fade in audio.

thanks - the same file I also used for a different movie and the final version of that one worked out fine. I tried just exporting the clip in question and using the exported version to render the movie, but had no luck. The raw audio file has no glitch, but i did chop off a few seconds of silence at the front of it, and increased gain by 8db in SC. Playback is fine in SC but the exported product has the glitch.

Think I’ll just have to live with it…
