Crash when exporting movie #1828

Closed John-Hollingum closed 6 months ago

John-Hollingum commented 6 months ago

Issue Summary

A particular project won't export mp4. When running the export movie function after some encouraging movement of the progress bars it halts with a 'something went wrong' info box (see content below). The program continues to run OK, and work is saveable. It will allow gif export; it just halts on mp4 export.

Other projects are exporting mp4 ok.

The problem project is the first I've tried with a camera resolution of 1728 971 all previous (working) ones have been at 1024768

------ OR BELOW THIS -->

Actual Results

I see and info box with this information

Expected Results

I'd expect the mp4 to be generated

This is your culprit:

[libx264 @ 00000150aeb3b8c0] height not divisible by 2 (1728x971) Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

When exporting as MP4 you can only use a resolution that is divisible by 2. This is not a limitation of Pencil2D but a limitation of the format itself. In order to export your project, you must either change the resolution to be divisible by 2, or use a different format such as AVI.

Since we already have an existing report of this issue at #1491 (to make the error easier to understand) I will close this as a duplicate. If you encounter other movie export issues, you can also check out the movie export troubleshooting guide on our forum.

Nice!
