What is the best way to encode chinese cartoons to VP9?

>liru isn't real

why even bother living tbqhfamerino

In booby format

Why would you do that?

>>61697982
Why not? I can't wait av1 forever

trac.ffmpeg.org

>>61698012
Then use h.264 like everybody else.

what animu you watch oniii chan

What are you even asking? CRF is not 2 pass by definition; it's a constant rate factor; and ffmpeg doesn't do 2 pass under any circumstances unless you provide -pass (1|2) as options and run it twice.

What are you trying to accomplish? Nothing is clear other than that you want to re-encode something to VP9.

So basically "-crf num -b:v 0 -quality best" is the way to go?

There is anything like -tune animation here?

Btw this season I'm watching new game, loli assasin the animation and aho girl.

Probably start princess principal too.

I know but when I use that single command from the vp9 guide my terminal give me typical output of a first pass (bitrate=0kbits...) and then start to encode.

And www.webmproject recommend a two pass for CRF based encode.


Constant Quality Recommended Settings:


ffmpeg -i <source> -c:v libvpx-vp9 -pass 1 -b:v 0 -crf 33 -threads 8 -speed 4 \

-tile-columns 6 -frame-parallel 1 \

-an -f webm /dev/null

ffmpeg -i <source> -c:v libvpx-vp9 -pass 2 -b:v 0 -crf 33 -threads 8 -speed 2 \

-tile-columns 6 -frame-parallel 1 -auto-alt-ref 1 -lag-in-frames 25 \

-c:a libopus -b:a 64k -f webm out.webm

VPx crf encodes can be 2 pass for some reason. I don't question it, the whole codec family is too bizarre.

>>61698216
I'm pretty sure setting -quality to 'best' will not only impact the encoding speed horribly but may also produce worse results than just leaving it at 'good'.
What are you even trying to do anyways?

>>61698301

But looks like ffmpeg send a two pass encode anyway cuz when I send a simple: "ffmpeg -i input.mp4 -c:v libvpx-vp9 -crf 30 -b:v 0 output.webm"

I have to wait a first pass full of: "frame=0 fps=0.0 q=0.0 size=0kB time=00:00:00.00 bitrate=N/A speed="

So looks like a two-pass encode is default for VP9 CRF based :/


Anyway I'm trying to encode BDMV m2ts chinese cartoon to VP9/Opus/WebVTT

>>61698216
Don't use -quality best, use -quality good and -cpu-used 0. Using quality best will likely make your encode take 2-10x as long for almost no improvement in quality / size. You should also copy audio / subs unless you any to re-encode it to FFmpeg's defaults (codecs and bitrates) for the webm container.

>There is anything like -tune animation here?
no.

>>61698283
You should teak some of those settings depending on your goal.

No, it doesn't and no it's not. 2 Pass processes the entire stream and collects statistics; that's not what's happening when you use crf and wait for the encoder to output.
