Bunny Stream accepts a wide range of input video, audio, and caption formats. The guidelines below help you prepare source files that encode efficiently, and the tables that follow list the exact containers and codecs we support.
Guidelines
- The total storage used to store your encoded video files may be larger than your source video file size
- Encoding compresses your input video file into multiple video files of different resolutions, sizes, and formats for web streaming
- The higher the quality of your input video file, the higher the quality your video encodes will be
- Use uncompressed video formats or the highest quality compressed videos where possible
- The following additional options will increase video storage when enabled
- MP4 fallback
- Keep original file
- The number of enabled Premium Encoding codecs will impact your storage usage
- The number of enabled resolutions will impact your storage usage
- Premium and free encoding does not deinterlace your video, ensure your input video is progressive format and not interlaced before uploading
- Portrait video orientation is supported
- 1080 width x 1920 height
- 720 width x 1280 height
