Encode video > Save MP4 causes error "No such file or directory" or Output file "does not contain any stream"

[Hyper Sonic]

After capturing a video, Encode video > Save MP4 never worked for me. The popup says "Save to GIF" so I'm not even sure what I'm supposed to select, and if try the following:

Entering a filename without extension:

App bottom message:

Wrote mp4 to filename (nil)

Terminal:

Unable to find a suitable output format for 'filename'
filename: Invalid argument

Entering a filename with extension .mp4 or .gif:

App bottom message:

Wrote mp4 to test.mp4 (nil)

Terminal:

[image2pipe @ 0x558eedfa37c0] Could not find codec parameters for stream 0 (Video: png, none(pc)): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options
Input #0, image2pipe, from 'pipe:':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: png, none(pc), 60 tbr, 60 tbn, 60 tbc
Output #0, mp4, to 'test.mp4':
Output file #0 does not contain any stream
du: cannot access 'test.mp4': No such file or directory
closing pipe

Entering path to an existing MP4 or GIF:

App bottom message:

Wrote mp4 to test.gif (1.4MB)

Terminal:

[image2pipe @ 0x56199b4827c0] Could not find codec parameters for stream 0 (Video: png, none(pc)): unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options

Output #0, gif, to '/home/leyn/Pictures/GIF/opt/test.gif':
Output file #0 does not contain any stream
closing pipe

I assume the popup should say "Save to MP4" and I should be able to either override an existing .mp4 or enter a new .mp4 name, then it should export there.

Gifine is a simple wrapper over a series of command line commands, so if you're getting an error then it's likely one of those commands is failing for some reason. Perhaps there is more in the terminal that might point to the issue. From what I can tell from what you provided the ffmpeg command is failing on your system due to the arguments passed.

This is my ffmpeg and I've never had any issues with encoding frames to mp4:

I assume the popup should say "Save to MP4"

That's correct, the file dialog had a mistake in the title.

OK, next time I try I will run each line in my terminal directly to spot the issue then.
