Save Selection As JPEG - Quality Options?

Another thing I wondered about, is whether that script needs a certain version of python to work?

It doesn't rely on any (external) Python interpreter at all. The minimal subset of Python Avidemux uses is contained in the libADM_script_tinyPy.dll plugin.

I should probably add that I use ZIP-packaged Avidemux builds for testing purposes on Windows (there are no other reasons for me to boot it in the first place), unless I specifically plan to test the installer. I extract it into an empty directory and run the graphical executable simply by clicking on it in the Windows Explorer window.

Usually, there are quite a few different builds in different locations, but they are never extracted over another build and also never run concurrently.

SUCCESS!

I have done a few things.  I updated python to 3.13.2, which didn't seem to make a difference, unless I needed to reboot first but didn't before testing.  I see you posted about that and no surprise that it didn't make a difference.

Next I deleted the contents of the Avidemux installation folder.  I had thought that installing a new version over-top of the old was acceptable since it sees the old version, wants to install to the same folder it's in, and offers to keep the settings, but apparently not.

After clearing out the installation folder, reinstalled same version 2.8.2 r241212 again to that folder, standard install, and it has no problem with No Disk message, none of the other errors I posted about, ("so far" no errors at all), and it does use the script properly now to sequentially name and save PNG for all the frames instead of only the first 37 frames.

Thank you for the guidance!
