I know for photos i could throw them through something like Converseen to take them from .jpg to .jxl, preserving the quality (identical visially, even when pixel peeping), but reducing file size by around 30%. What about video? My videos are in .h265, but can i reencode them more efficiently? im assuming that if my phone has to do live encoding, its not really making it as efficient as it could. could file sizes be reduced without losing quality by throwing some processing time at it? thank you all
Offhand I think AV1 is supposed to be a bit better than H265, but I think the improvement would be pretty marginal. Also, that’s a newer codec with less support everywhere, so you might find yourself slowing down a lot doing live transcoding to a format with better support like H265 or H264, depending on your devices. Add in all the time transcoding your current files from H265 to AV1 and it might just be worth adding more storage space.
