To the webm encoder guy,
Why are you using multiple frames for your webms? If you are making a two-second webm (good practice, as some browsers get confused by very short loops), you can set the framerate to 0.5fps and save even more bandwidth

this file was encoded with the invocation
ffmpeg -loop 1 -i maki\ is\ cute\ 548.png -c:v vp8 -qmin 4 -qmax 6 -minrate 40M -maxrate 40M -t 00:00:02 maki1.webm
See the next post for the same file, encoded with the addition of a framerate argument

What is the advantage of using minrate and maxrate instead of crf when you have qmin and qmax set?

Use -deadline best, senpai. It allows ffmpeg to spend longer figuring out the the best way to compress the frame

2 seconds seems to be the sweet spot, but it probably shouldn't matter how long it is so long as you set the framerate appropriately

More like -r 1 -t 2, just like THE autist adviced us... The size difference is not going to be that big in theory as the additional frames are just telling the decoder to redraw the first keyframe

Web guy here: I encode a 2 second video with 1 FPS because it prevents unnecessary high cpu utilization.

What you just did (forcing 1 frame in 2 seconds) can cause high cpu utilization in so.e browsers.

tl;dr better safe than sorry and extram frame is like 1-2KB extra

Interesting, pic related now with -qmin 0 -qmax 0.

Problem however with these better quality options is that it doesn't really beat jpg in quality for the same file size, it's only in the autismo small files where some benefits could be had and that only benefits those living in US or in other 3rd world nations with trash tier internets

why use it though for these small files, a few kilobytes matter little compared to the inconveience of having a webm. And for very big images you can't zoom in(i. e. view parts in original resolution.

now do one with webm. That's right: you cant because theyre arbitrarily limited to 2048x2048 here on 4chan and were not allowed to use vp9 either

It's really annoying isn't it. I tried arguing on /qa/ about it but as usual the people who hang out there just wanted to agree with current policy

also, why bother with webp when VP9 webms would actually make a difference?

Yeah, cuckzilla is probably paying 4chan to not adopt webp yet in hopes of the sjw jpg encoder becoming relevant. Though eventually as firecocks plummits to 1% marketshare they will probably add support for webp out of the blue.

Only a matter of time I guess.

>CRF does jack shit in VP8. Changing the qmin/max settings is the best quality control possible in VP8.
Could you elaborate on this point?

I use "constant quality mode" (or maybe it is constrained quality) to encode webms for 4chan. A lot of times I will use two passes.

Changing the '-crf' parameter makes a difference. The difference is noticable to me when crf is changed in the range of 5 to 10 (or more).

When you say it doesn't do anything, are you saying that with respect to this thread (making static 2 second images)...or is there something more that I am missing?
