Yodeck supports a wide variety of video formats!
Videos that you upload on Yodeck are automagically converted to industry-standard formats (H.264 with AAC audio) with high quality settings. This way, Yodeck can provide a high-definition viewing, with the smoothest playback possible.
YouTube and Vimeo videos are supported out-of-the-box, so they just get downloaded in the best possible quality (up to 1080p right now).
Live Streaming Videos (YouTube, Vimeo, UStream, or custom HLS or RTMP/RTSP streams). These will have to be delivered by the stream in H.264 format to make sure they will be played back on Yodeck Players.
PowerPoint files are converted to videos on our servers, retaining all transitions and animations.
