Chirp between every clip Corel VideoStudio 2023

[koerper70]

I frequently get a chirp between clips on rendered videos from Corel VideoStudio 2023. The chirps aren't in the source files and aren't there during playback within VS. They are only present in the exported mp4 file. I have tried multiple different output formats, hi/low def, hardware encoding off and on, smart rendering off and on, converting source files to AVI before editing, closing all other running apps during export, recording source files using different hardware.... Nothing seems to have any effect. I'll go months without this problem, then all of a sudden it starts up again.

Any helpful recommendations?

I don't have a lot of personal bandwidth for learning a new platform, so that would be a last resort.

I also tried fade-in/fade-out on every single clip. No go. Same problem.

Disclaimer: I don't use CVS. This is a stab in the dark based on an issue we had with our editor.

Try matching the source file's audio Hz to the export (or resampling your source file to match): eg if the export audio is planned to be 48khz, try using a 48khz source file. Yours may be 44.1khz.

[koerper70]

Both the source file and the output are 44.1khz.

Doesn't the editor have a dedicated forum? Or support?
Might get more luck there - I don't hear it mentioned too often here.

Sounds like an error during the rendering. Have you reviewed the project log?

[koerper70]

No, Corel shut down their user forum a while back.

If there is a project log, I don't know where to find it, and I haven't found anything on their website or in the user manual.

There's a continuation of the forum here, as well an archive of the old forum.

What version of Windows are you using?
Did you install any codec/filter packs - this might be an issue if it uses system codecs (probably directshow)
to access and decode the source files

[koerper70]

Excellent. Thank you Dave!

I'm using Windows 11 Pro. I only have the NewBlue filters that came with CVS.

I also tried splitting off a bit of either end of each clip and muting that mini-segment. That worked in a couple of places, but mostly didn't.

I saw your thread at the other site, interesting developments.

To facilitate their suggestion, I would do it this way:
Set your project to create uncompressed audio (WAV, etc.)

Save you project as normal (audio and video)

Drop the video onto Audacity and it will extract the audio for editing.
Edit out the blips and export to a final format of your choice.

Remux the video (using something like Avidemux) with the new audio

Hopefully, they'll get enough info to diagnose and fix the problem.

Thanks. Dave. I think I've solved the problem, using a process pretty close to what was recommended there.

1. Complete the video editing without doing any cleanup on the audio.
2. Export only the audio track to WAV. Interestingly enough, WAV format didn't have the blips/chirps/hiccups at all. They are present in all of the compressed formats, so it must be something about the compression that is causing it.

At this point, I could just mute the entire video track and replace the audio with the WAV file since it is a single, unbroken segment. However, the advice to use Audacity to clean up the audio is probably good, so I polished the audio track in Audacity and then added it to my CVS project. It's a pain that CVS is so buggy, but this workaround is easier than I was expecting.

Hey that's great. Audacity can also compress the audio when exporting if necessary
