  • AV1 and VP9 are likely going to be your highest efficiency “free” codecs. AV1 is the way to go if you mean free as in free open source. It’s not very likely to be implemented in many TVs or set-top-boxes, but VLC/ffmpeg will be able to decode any of these. Webm uses vp8 or VP9 which are “free”(made by Google) but it’s just more specific settings for sharing online/viewing in browser.

    H264/H265 has license fees for non-free software and hardware, but they will be your most widely supported option. H265 is approximately twice as efficient as h264 (meaning you can get the same quality of encode from half the file size).

    Regardless of preset I think you can get handbrake to encode something reasonable from any of these codecs. Especially with DVD video you’ll be able to crank through videos with modern high efficiency codecs
