I often go through and get the settings for a number of runs and put them in a batch file to be executed one by one automatically using "call " commands. This allows me to pause the processing whenever I want and start it again. I have noticed that some of the filters when enabled break the ffmpeg command when you export it and then try to run it in the way I described. When trying it I get an error that there is a trailing option and then it fails outright.
If I remove the -metadata and its associated content the command works. I am assuming it is because of the characters in the content? Once I remove that part, the command works. Here is an example of the part I removed:
“-metadata” “videoai=Slowmo 100% and framerate changed to 29.97 using apo-8. Deinterlaced and enhanced using iris-1and recover original detail at 100. Changed resolution to 2560x1920”
