I did a quick test here,... thanks to Phyllis. My tests is only for rendering to: FFMPEG | webm Audio: webm.webm Video: vp9_1920x1080_24or25or30fps.webm. And it compares "cin-x86_64_older_20240417.AppImage" vs "cinelerra-5.1-ub16.04-20201031.x86_64-static". The second one Cinelerra-GG version uses FFmpeg 4.3, if I am not wrong. My Operating System is UbuntuStudio_16.04_LTS_64bit. The Cinelerra-GG AppImage shows messages on the Command Line. And the old version is faster than the new,... maybe because of the messages in CLI? I don't know. Below the summary of the tests.

There is an AppImage on the server with FFmpeg 7.0 included in the build if anyone wants to test. It should work on just about any 64-bit O/S but Help is not included (nor alternative shortcuts). https://cinelerra-gg.org/download/testing/cin-x86_64_older.AppImage
