some times I use the direct video output of Bongo and run in the issue, that the set frame rate isn’t used.
For example I want to create a quick preview of a 60s animation at 10 fps. But a mp4 with 24s is created.
If I open my single frames per Hitfilm and write a mp4 than 10fps is no problem. So, it should be possible also for the Bongo movie creator tool.
