Compressing video for the web can be a fine art but it can also be relatively simple. EngageMedia 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 Handbrake which works on all platforms. Other alternatives include 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.

The following are our two main recommendations for encoding video (XVid and Ogg Theora), followed by one setting we recommend you use if you have any audio-video sync problems after uploading to EngageMedia. We encourage the use of free software and patent-free codecs where possible, but if you do experience sync-problems, use this final setting for Quicktime Sorenson instead.

We do however accept almost all formats and many codecs. Others you might want to try are MPEG4, H.264, OGG, MPEG1, and DivX.

These settings should result in a file that is about 5-10 megabytes per minute in size.

If your video is large and you have a slow internet connection please contact us and we'll help you upload it.
