Video explains that Vimeo supports WEBM format of videos and we should not convert videos before uploading. And also the quality is good.

We do not convert videos any more.

Create WebM videos directly.

Why does Miro Converter create far smaller files, but does not lose quality?


It is called compression of video file. It just compress it just like zip/rar. It uses x256 video codec. There is the same alternative for images.

Does Miro the same as Handbreak?

Yes, exactly.

Original Not Compressed Videos

Put compressed folders as subfolders of the video folders


We can have problems with the folder structure that is different in:

  • Original Webm folder
  • Compressed MP4 folder

There we move the compressed folder as subfolders.


We can also think about deleting the Compressed folders, once they are uploaded to Vimeo. I suggest that we don’t delete them. Maybe can change to another provider later, other than Vimeo.
