Lowering the bitrate and making the size smaller helps

Paint is delicious.

My method of choice is

ffmpeg.exe -i input.webm -c:a copy -c:v libvpx-vp9 -b:v [bitrate goes here] output.webm

Mess around with the bitrate until you get the size right.

If you don't have ffmpeg you can get it here http://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-latest-win64-static.7z

>libvpx-vp9

thanks, I've been missing this from all my conversions, I've always just been using libvpx. vp9 really reduces the file size. It takes a lot longer though

Also, I don't know if it's just my imagination but I was always using the -crf option which always seemed to make a noticeable difference to me. But now with vp9 it seems like that option isn't needed as much. I was only able to notice a slight difference when doing a black and white video (bad apple) so edges could really stand out and there was a little bit more blur during fast motions without -crf.

It's kind of hard to find detailed information on this stuff.

Make sure you have the latest version of libvpx - 1.4.0 really speeded things up.

They've been doing a lot of webm science over in /a/, which might have some more information for you.

Webm tangentially related - the result of some of their science.

I love this video

Also, in general, for ultimate quality:

ffmpeg.exe -i input.mp4 -c:a opus -c:v libvpx-vp9 -b:a 96k -b:v [bitrate goes here] -pass 1 -an -f webm NULffmpeg.exe -i input.webm -c:a opus -c:v libvpx-vp9 -b:a 96k -b:v [bitrate goes here] -pass 2 output.webm

2-pass encoding is best pass encoding.

Source itself wasn't that great to begin with so I don't know how if anything could be done about it. I downloaded https://www.youtube.com/watch?v=srL6k_gqhME as 360p .webm.

Here's the nico-nico original http://smile-fnl10.nicovideo.jp/smile?m=15346128.14211 if you wanna try optimising it better.

Also who are you quoting?

Also, the code tag in my last post should be on two lines, splitting at NUL / ffmpeg.exe

For the record, if you're not too interested in having those moving lines on the screen you could just set the videos FPS to 1 and significantly reduce the file size.

The audio stream from your file is just 2.8M
