FFmpeg outputs something like:

frame=  692 fps= 58 q=28.0 size=    5376KiB time=00:00:28.77 bitrate=1530.3kbits/s speed=2.43x

Better FFmpeg Progress outputs something like:

⠏ Processing abc.webm ━━━━━━━━━╺━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━  23% 0:00:04 00:15

Where:

• Processing abc.webm is the description of the progresss bar.
• 23% is the percentage progress.
• 0:00:04 is the time elapsed.
• 00:15 is the estimated time until the FFmpeg process completes.

As you can see, the output of Better FFmpeg Progress is much more useful.

Installation

pip install better-ffmpeg-progress --upgrade

try:     process = FfmpegProcess(command)     # Uncomment the line below if you want to use tqdm instead of rich for the progress bar     # process.use_tqdm = True
process.run() except FfmpegProcessError as e:     print(f"An error occurred when running the better-ffmpeg-process package:\n{e}")
