Try version 9.9.9.3, I think this should fix it. I'm also no ffmpeg expert, so I'm not sure if my chosen options are good ... but at least they work :D

Suggestion [3,General]: The command bbb-dl-batch was not found, but does exist in the current location. Windows PowerShell does not load commands from the current location by default. If you trust this command, instead type: ".\bbb-dl-batch". See "get-help about_Command_Precedence" for more details.

thanks :D

How do we use ffmpeg -fast -very-fast arguments? Also, while you have found you active, can you activate ffmpeg if there are any presets that will enable it to process in higher quality :D

It does not really make sense to use presets with higher quality, because it is only a slideshow... We have no quick movements, no color shifts... nothing special. The result from preset fast to slow is nearly the same, it only takes more time to process. But if you want I can add a option to set the preset by option.

See also https://write.corbpie.com/ffmpeg-preset-comparison-x264-2019-encode-speed-and-file-size/ and other comparisons you can find online..

What really would make a difference, is if someone would take on this project and change the frame capture algorithm so that the screenshots are not taken in viewbox size, but in the size of wanted output resolution. That would make the output a lot lot better.

I can add a option to set the preset by option.

Make a new issue if you want that

I added the --preset option in v0.9.9.5
