I opened Avidemux 2.7.3 GUI (Latest version in the Mint/Ubuntu repo) queued several videos I wish to convert from various formats.
I could 'save' the file in the GUI. Conversion worked great, as always.
Opened up the avidemux_jobs program. There are the movies waiting to go. If I press 'Run Jobs' button. It runs through the entire list, failing, one after the other. (7 seconds each). If I right click and select 'Run Now' the individual job fails.
