What codec is the best for keeping quality of a movie but also decreasing the size?
| The mp4 probably uses .h264, the better one is .h265 HEVC which is used in 4k blurays. But for the same quality on 480p I don't know if it will reduce it that much.
On the open source side there's av1.
Thou personally I dont like to reencode an already encoded video, there will be loss.
Either download them already in h265 or buy other hdds.
| Give av1 a try, you'll probably want svt-av1 encoder as everything else is rather slow
you can also just re encode in x264 on a higher preset and maybe add some de-noise if it doesn't ruin the picture for you
From what I've seen av1 artifacting shows up as just being a bit blurry where x264 is blocky and more noticeable
| VP9 webm has the best quality-to-space, but encoding times are terrible and probably not worth the trouble.
| >>881756 is vp9 better than av1? My understanding is av1 is the successor to vp9 more or less and yeah can confirm vp9 encoding is slow
| its parcticly free to just pick some encodings try them at diffrent settings and compare visuals / file size
you can even try diffrent universal compression which might work well if you are archiving loads of movies

| I've started downloading movies and on average a 480p 90 minutes film takes up around 700-800MB. I wonder if there's a way to work around this. I'll be happy with being able to cut it down to 500MB if not even less. To put it briefly, the movies are in MP4 format and their bitrate averages between 800 and 1200, depends on the movie. If it's bigger it looks better but also weights more. So I am just curious if there's a more efficient way to store those.
