Description Takahiro Kamai 2024-07-14 00:22:40 UTC 
SUMMARY
In rendering to a video file, the progress bar grows too fast.
For 1 hour video, the rendering takes an hour or more in my computing environment.
However, the progress bar grows to 100% in a few minutes.
The rendering itself will be finished normally.

STEPS TO REPRODUCE
1.  Make a project from one video clip and one audio file.
2.  Push "Render button" or select from menu "Project" -> "Render"
3.  In Rendering window, select MP4-H264/AAC (Generic (HD for web, mobile devices...)
4. Select Full project
5. Render to File

OBSERVED RESULT
The rendering itself was finished normally.

EXPECTED RESULT
Progress bar is expected to grow up to 100% when the rendering finished.

This should be fixed in 24.08 version. Would be nice if you can test a daily builds to confirm:
