Hello, I am currently making Webms and was wondering how I could decrease the file size of Webms so that I may post them to sites that have a limit on the size
Here is a Webm I have created http://webmup.com/GiuOq/ that Webms file size is 13.9 MB and I was wondering how I could decrease it's size, I would like to decrease Webm file sizes to 3mb if at all possible?
Thank you for any help in advance

filesize = bitrate * running time
Therefore reduce the bitrate to reduce the filesize
If everything else is the same, reducing the bitrate means lower quality
If you use better compression, you can improve the quality at given bitrate (or filesize) . e.g .VP9 offers better compression than VP8 for WEBM, but it's not as widely supported yet, and slower to encode and decode
You might consider denoising (noise impairs compression) , and/or reducing the resolution, if you use intend on using low bitrates
What do you convert with?
maybe the bitrate is too high or CRF value too low?
I can compress a 30sec anime with FFmpeg into 3-4MB:
-acodec libvorbis -aq 3 -vcodec libvpx -crf 20 -b:v 1M -cpu-used 0 -threads 8
