File name of the video conversion result to MP4 format

[richardferrym]

Description of problem or question:
For batch processing, why does the file name result always have an m4v extension even though I have changed the video encoder to MPEG-4? So, I always rename each video one by one. Is there a feature to rename all conversion results to MP4 (.mp4) extension?



Steps to reproduce the problem (If Applicable):
batch files (folder).



HandBrake version (e.g., 1.0.0): 1.4.2




Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Windows 11
