To change the CRF value for x265 encoding include "-x265-params crf=23". It's just -preset slow -b:v 2000k, but I find that constant bitrate will lead to a lot of variance in quality between scenes/releases. X265 is the CPU-specific library for H265. y4m -c copy xxx. If you have ffmpeg compiled with vmaf you can use it to automatically gauge the quality of the output video to test different encoding settings: ffmpeg -i distorted.

Choose the slowest preset that you have patience for. 265 encoding is generally considered lower quality than the CPU based x265 encoder. There is no best settings because quality is subjective, but the usual guidelines of libx265 (assuming you are using this encoder) is similar to libx264: Use the highest -crf value Balancing encoding cost and streaming bandwidth, you’ll learn how to choose the optimal preset based on the expected viewer count and the optimal core count for cloud instances to encode your video. As a reminder, here is an overview of suitable settings for good quality. Members Online WastyFace93 FFmpeg has a command line option -target ntsc-dvd which seems to setup options appropriate for typical DVD style encode, though possibly not "optimal" lossiness just a default DVD style encode.

Fair enough, then yea x265 will probably be your best bet. I will note one use for frame-threads=1 though -- stability. Putting it all together, we can convert the sample. Realistically speaking, if you really want to peg your 16 core CPU at 100%, I would run 2 instances of 16 thread encodes (you gain maybe ~5-10% efficiency), or lower the CTU to 32 to increase the theoretical limit to 33 threads.

Twilio’s Head of R&D on the need for good data. The CRF setting controls the Constant Rate Factor of the video, the The correct syntax to enable lossless mode for x265 encoder in ffmpeg is -x265-params lossless=1 (you need to append =1). Of these 4 setting which one do you think is best? -crf 21 -preset medium -crf 20 -preset fast -crf 20 -preset faster -crf 18 -preset superfast Using some sample trials of encoding a minute starting from middle of some videos using -ss and -t, these 4 settings yields about the same filesize. GOPs are open by default, and you can use the option above for closed GOPs. I found by testing that FFV1 compresses vastly better (file size = ~80% of x265) at least on some kinds of video (if best settings are chosen for both codecs). Communities for your favorite technologies.

In this case, you are using two different encoders, so you get different bitrates. Note that the camera follows me a bit too much to the exclusion of the slides (in the video), so the most efficient way to move through these materials might be to just read the handout.
