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
ffmpeg -loop 1 -r 0.5 -i maki\ is\ cute\ 548.png -c:v vp8 -qmin 4 -qmax 6 -minrate 40M -maxrate 40M -t 00:00:02 maki2.webm
this is the original file btw
What is the advantage of using minrate and maxrate instead of crf when you have qmin and qmax set?
Makiposter, don't bother with an autist that has higher powerautism level than you
I like her 7 foot long arm.
shit
Fuck I'm dying hahahaha
Kek. was this on purpose?
maki has extremely long arms so that she can touch your heart, wherever you are
Why are you encoding still images as a video at any frame rate?
because its a more optimal method of lossy compression than jpeg, and Cred Forums doesn't support webp
ffmpeg -loop 1 -r 0.5 -i $(find ~/makis/ -iname \*.png | shuf -n1) -c:v vp8 -crf 4 -b:v 9001k -deadline best -t 1 out.webm
Use -deadline best, senpai. It allows ffmpeg to spend longer figuring out the the best way to compress the frame
nice ty
also i didnt know about shuf that's super handy
testing if this one confuses my browser as well, and do
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

Quit giving the shitposter tips

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

whoops meant to quote CRF does jack shit in VP8. Changing the qmin/max settings is the best quality control possible in VP8.

You're late. We already started circlejerking without you. At least go get more lotion while we cool down for round 3.

now you're being silly

Original image: click to view it in full size
Webm: click to play/pause
WOW
Useful!

you seem upset
webm bro pls webm this and save me a kb or two if possible.

Okay lotion boy, unzip your pants.

>CRF does jack shit in VP8
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
Not sure how many more bytes i can take off this
...
it looked like shit long ago. just stop
still looks better than the png desu
and that's the smallest I can go
ffmpeg -loop 1 -r 0.5 -i input.png -c:v vp8 -qmin 63 -maxrate 1k -deadline best -t 00:00:02 output.webm
than the jpg
its late
...
>taking shitposting this seriously
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.
maximum fucking kek
i only have 2 tabs open but my browser is eating 30% cpu for some reason
did u just hack me
...
ChromeOS doesnt have this problem
>only 30%
now do one with webm. That's right: you cant because theyre arbitrarily limited to 2048x2048 here on Cred Forums and were not allowed to use vp9 either
>implying that i haven't tried already
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
webp isn't supported in firefox so no.
also, why bother with webp when VP9 webms would actually make a difference?
Why does ksthis happen?
Yeah, cuckzilla is probably paying Cred Forums 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.
Shitty video player. Use mx player or Clover.
pix format in that one is yuva480p which your media player can't hand, this is with yuv480p and should play normaly
do the world a favor and kys. you're too fucking autistic to live.
yuv[a]420, not 480
>no fun allowed
good luck with that
get a fucking blog.
What do I need a dog for? To bark and shit itself every 5 minutes? No thanks.
fixed
>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 Cred Forums. 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?
I can't zoom in on these...
I can zoom in on this.
