    Are there any newer codecs for images and videos?

    Hello, let's say that I'd like to archive several images and videos. I know that I can use the legendary JPGPacker to encode and compress my jpg files (otherwise they are not that much compressible). Is there something similar I can do with video? Are there any new codecs for images and video that can provide very good lossy compression (so it would be viable to convert jpg and mp4/3gp/flv files to those new codecs)?

    Remember, I want to archive those files, so I don't really care that they won't be immediately accessible.

    Thank you for all the suggestions and for taking my kind of noobish question.

    Have a good one.

    -- to compress/archive videos you can try the new "AV1"-fileformat

    - i think - you should wait to the first release of "dav1d"

    - https://code.videolan.org/videolan/dav1d

    - this seems to be very good

    ---

    -- to compress/archive pictures you can try the new "HEIF/heic"-fileformat

    - ("High Efficiency Image File Format")

    - a *.heic-file can save up to 50% filesize (if we compare to a traditional *.jpg-File)

    - HEIF with opensource: https://gpac.wp.imt.fr/2017/06/09/gp...port-for-heif/

    for image: AVIF, which is AV1 + ISO-BMFF.
    * https://github.com/AOMediaCodec/av1-avif (and https://github.com/AOMediaCodec/av1-avif/wiki)
    * demo page: https://cconcolato.github.io/wasm-av1/

    IIRC the bitstream for AV1 was unfrozen, so you might want to hold off on encoding your video library in AV1

    Correct. Unless a faster speed setting is used. I'm not sure if the reference encoder is multi-threaded. The way dav1d seems to speedup decoding is by decoding each frame independently from what I've read. Encoding could be sped up by splitting a video file into segments and then encoding each within a thread. This is what I do with rav1e, just for fun and entertainment. I also wrote a GUI To accomplish this: https://moisescardona.me/rav1e_gui

    The specification has not yet been frozen.
