Format

Resolution

H.264 video with AAC sound: plays on every phone, computer, TV and site. At its own size, a track the format keeps is copied as it is: quick, and nothing is lost.

Converted by your browser's own codecs (the graphics card's where it has them); writing video again takes about as long as the video plays, or less. AVI, FLV and WMV aren't read; the converted video is held in memory until it's downloaded, so very large ones may not fit.

How to convert a video

Pick the format: MP4, WebM, MOV or MKV.
Keep the original resolution, or make it 1080p, 720p or 480p.
Download each video, or all of them in a ZIP archive.

Questions

Which format plays everywhere?

MP4 with H.264 video and AAC sound plays on every phone, computer, TV and website.

How long does converting take?

When the format can keep the video as it is, it's copied: quick, and nothing is lost. Otherwise it's written again by your browser's own codecs (the graphics card's where it has them), in about the time the video plays, or less.

Is there a size limit?

Videos are read as they're needed, so long ones work, but the converted video is held in memory until it's downloaded, so very large ones may not fit on a phone.
