Compressing video for the web can be a fine art but it can also be relatively simple. Screensessions automatically creates a small version of your video to view online, so it's a good idea to create a file that a film festival or a community TV station could download and screen.

For encoding your video we recommend using ffmpegx for mac, Virtual Dub or MediaCoder for Windows and Gtranscode or ffmpeg2theora for Linux. These programs cost nothing to use though you can donate to assist their development. You can also use a range of proprietary video-encoding applications such as Quicktime Pro, ProCoder or Cleaner or even encode the video straight from the timeline in Final Cut Pro, Vegas Video or Premiere.

We do  accept many codecs:  .avi,.qt,.mov,.mpeg,.mp4,.mpg,.asf,.wmv,.3gp.
We do NOT accept these codecs: .divx, .flv

Important Note: Video File Size
Uploading a video with more than 50 megabytes is not allowed.
