Slow processing time

The fewer issues I have to read, the more new features I will have time to implement, so I ask that you please try these things first

• Try with a different kind of file to confirm that the problem is related to just this file.
• Try with the newest version from GitHub
• Read the documentation and FAQ, Known issues, Troubleshooting
• Search for your problem under Issues or Discussions

Steps to reproduce

I am using the latest version of the program via PortableApps. With older versions, processing took a long time only because it rendered the empty frames; otherwise, I could generate the output quickly, even with high-resolution video.

Now, however, I am using the latest version, and the processing time is extremely long.

Expected behavior

I want the processing time to be normal (fast).

Actual behavior

The processing time is long.
