This error showed with a 100% progress stitch.
Just did a 2nd stitch with completely different files which ended the same way. Gets to 100% and brings up that error.
Can you find the error in the log file? There should be more details about this error in the log.
On Windows the log file is C:\Users\<username>\AppData\Local\actionstitch.com\ActionStitch\actionstitch.log . On macOS, the log file is /Users/<username>/Library/Application Support/actionstitch.com/ActionStitch/actionstitch.log .
Wouldn’t even know where to search for that log file. Punched it into so many places with nothing coming up (console app, finder, web browser).
Further to this, I tried another stitch without audio and to the onboard SSD (instead of external) which worked. I am hoping it is the audio issue, because I could run into space issues if I have to save everything to onboard SSD. The external has a weird symbol after the 1gb in the destination file name when stitching (it’s like 5 horizontal lines.) Thought maybe the symbol sits outside what the program allows (when I looked up the ordinal issue online)
Issue was the file location name. The weird symbol Mac included in its name caused the issue. Just did a with audio stitch and it worked fine.
