Video Encoding & Transcodes

Each video file uploaded to Vidcaster goes through a process of encoding to allow for web playback. Due to different viewer bandwidth capacities and varying device types, we create multiple encoded versions of each video for optimal playback in all scenarios. If you are trying to decide how to export your videos to achieve the highest quality in the Vidcaster player, follow the settings below of our highest quality transcode, HD.

Vidcaster creates three encoded versions of your video, HD, Med, and Low. These are called Transcodes. All Vidcaster Transcodes have a video codec of H.264 and an aspect ratio 16:9. Consult our Upload Formats for a full list of accepted video and audio codecs.
