Is this speed is normal? [NEWBIE]

Post by colethegamer »

Description of problem or question:
Im totally newbie in the area of transcoding and using HandBrakeCLI. I just want to know if this speed is normal.



Steps to reproduce the problem (If Applicable):
flatpak run --command=HandBrakeCLI fr.handbrake.ghb --input "$video_file" --output "$subfolder/tmp_video_file.mkv" --encoder x264 --quality 22 --rate 30 --audio 1 --aencoder av_ac3 --subtitle-default 1 --srt-codeset UTF-8 --srt-file "$subtitle_file"

My goal: Transcode the video file into h264 with some normal quality and use AC3 audio and add a default subtitle from .srt file with UT8 coding.
Its working perfectly but it takes about 30-40 minute to do a 2 hour long movie.



HandBrake version (e.g., 1.0.0):

HandBrake 1.7.2


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

Ubuntu 20.04

Yes, the issue is that your cpu has so many cores, but video encoding can't scale too well to more than 12 cores anyway.

Thanks for your answer, just another quick question in that case. Can I start multiple in the same time?

The GTK GUI doesn't support multiple parallel encodes yet, it has been implemented only on Windows and macOS at the moment.

But if you use the CLI (as you did in your example encode above), you can start as many instances as you like.

A few guy told me who are using the same server from the same provider, they can go up to 3min / movie. Is it possible with this hardware somehow? I cannot find a solution to that. Thank you.

For super fast encodes they are probably using a hardware encoder:
