Which video format should I use when uploading to 23 Video?

23 Video accepts all common video formats in all resolutions, but with a few means you can guarantee yourself faster upload and processing with the highest possible quality:

Video size

Full HD format on 23 Video is 1920x1080 pixels with a bitrate of 3000 kb/s, which gives great quality in fullscreen. If you upload in a highter quality, your video will be converted and scaled down while we prepare it for playback on the web. You can reduce your upload time by preparing the video at a bitrate of about 5000 kb/s.

Video and audio codec

Browser playback of high quality video happens by converting the incoming video to MP4 with H.264 as the video-codec and AAC as audio-codec. We recommend that the video is uploaded in MP4 and H264 − simply because the processing will be faster and you'll obtain the best quality when the video is played in a web browser or through podcast.

File size

When you upload a file to 23 Video, we'll be optimizing it for web distribution: This means preparing it to play in Adobe Flash and on mobile devices, but it also means compressing it to a file size that can actually be downloaded on a broadband connection.

As a general rule, our standard video stream is about 6 MB per minute, and our HD stream is about 11 MB per minute. This means that your upload time can be minimized while still getting maximum video quality by uploading videos with a file size of about 20-25 MB per minute.
