I assume you mean for mp4 files? It's run via the media converter to ensure the atom is moved to the start for streaming. Also that it is compressed according to the settings.
yes but with the same reference twice encodes the file even
example I send monsuperfilm.avi
the next day my friends sending the same video
ben the site will re-encode it as a different file instead of directly to the location of the first
Ah I see what you mean. Yes it will re - encode the file as effectively it's a different file. So when the avi is re uploaded there's no way to link it to the original. I'll see if there's anything we can do with this for the v4 release.
