HandBrake fails to convert

[Filippo]

Hello,
I'm converting a 4K video to reduce its size but HandBrake fails after many minutes of encoding with this error:

The filename is short and the destination directory is in a folder in the same directory of the source, I tried many attempts but still getting error.

Try converting the same file in Avidemux or Virtualdub and compare the results.
If it stops in a similar place there may be source file problem

The reason may be: 1. Insufficient memory. Encoding 4k videos with x265 needs a lot of RAM; 2. Crashes near frame 19372 might be due to corrupted data in the source file. 3. Advanced settings like lslices=4 can cause compatibility issues.

The solutions are: 1. Close other memory-heavy apps during transcoding, or change to x264 encoder; 2. Reset to default presets in Handbrake, just tweak CRF (24-28) and resolution, and turn off all extra advanced options; 3. Report the log errors to HandBrake; 4. Try alternatives like ffmpeg, shutter encoder, or cisdem video converter.

Have you tried using FastFlix? It's a bit more intense as it has a lot of settings options, but the result, I find, is a better encode than Handbrake (especially if you have an NVIDIA video card). I only use Handbrake when nothing else works due to the lack of settings.

Use clever FFmpeg-GUI and scan the 4k video for errors.
Load it, click main page, click various, click scan for errors, click scan.
If errors are found, an error file is created.
