I want to convert a bunch of videos from x264 to x265, but I need to do so with ffmpeg in terminal because it's a remote server. These are my Handbrake options (listed items are ticked):
Summary tab
- Web optimized
- Align A/V Start
Dimensions tab unchanged
Filters tab
- Sharpen - LapSharp, preset: Medium
Video tab
Video codec - H.265 (x265)
Framerate (FPS) - 30 - Peak Framerate
Quality - Constant Quality - 28
Encoder preset - Medium
Encoder tune - None
Encoder profile - Auto
Audio tab
- Audio track - AAC, bitrate: 128
Subtitles tab - No subtitles (remove if exists)
This is the ffmpeg command that I've managed to compile so far:
ffmpeg -i input.mp4 -c:v libx265 -crf 28 -c:a aac -b:a 128k -max_muxing_queue_size 400 -movflags +faststart output.mp4
I have the following two questions:
- Does the ffmpeg command provided list all the options except the peak framerate, sharpening filter and removing subtitle ones? How do I incorporate these three?
- Slightly unrelated, but does having
-max_muxing_queue_size 400negatively affect file size or video quality? I've only included this because I'd ran into encoding errors in the past.
Thank you.
My Handbrake log with the above options, if it helps:
