Hi, I would like for you to send a file to me. First run:

auto-editor your-vid.mp4 --temp-dir temp

then when it fails, send the temp/0-0.wav file.

[Aelerity]

It did not fail/get the error when I did that and just returned the expected output video.

I tried a few other tests.

auto-editor C:\Users\talkp\OneDrive\Documents\auto_editor_vids\sup.mp4 <- dont get the error auto-editor C:\Users\talkp\OneDrive\Documents\auto_editor_vids\sup.mp4 -v 2.5 <- get the error auto-editor C:\Users\talkp\OneDrive\Documents\auto_editor_vids\sup.mp4 --temp-dir temp <- dont get the error and also for some reason? auto-editor C:\Users\talkp\OneDrive\Documents\auto_editor_vids\sup.mp4 -v 2 <- dont get the error

I have 7 different vids in my auto_editor_vids folder and I ran the command in powershell

$files = "C:\Users\talkp\OneDrive\Documents\auto_editorvids" $filteredFiles = Get-ChildItem $files -Filter *.mp4 | Where-Object { $.Name -notlike "*_ALTERED.mp4" } foreach ($f in $filteredFiles) { auto-editor $(Join-Path -Path $files -ChildPath $f) -v 2.5 --no-open } 4/7 of the vids were successfully altered without error

$files = "C:\Users\talkp\OneDrive\Documents\auto_editorvids" $filteredFiles = Get-ChildItem $files -Filter *.mp4 | Where-Object { $.Name -notlike "*_ALTERED.mp4" } foreach ($f in $filteredFiles) { auto-editor $(Join-Path -Path $files -ChildPath $f) -v 2 --no-open } 5/7 of the vids were successfully altered without error

I confirmed that this happens on Windows (but not MacOS) with:

auto-editor example.mp4 -s 2

Thank you @Aelerity for making a bug report. No further action is needed.
