Does someone have a script that converts all videos files from 264 to 265 and changes the name?
Even an attempt at it would be appreciated
looks like I will not convert anything at all.
It is definitely not worth converting x264, even less x265, to av1, if you are the only consumer. Just think about it. To get any “significant” space gains, while keeping a close to original quality (you will inevitably lose some detail), you need to spend maybe at least 3-4x more time encoding than the actual total video length, probably more, maybe 5x. Taking an average of 3GB/hour, 2TB is about 650 hours. x5 that’s like 3250 hours. An 8 core ryzen will have like 150W total system load encoding av1. 3250h * 0.15 kWh =~ 500 kWh. 500 kWh * 0.15$/kWh (I took an optimistic electricity cost for these days, might be a lot more depending where you live) = $75 in electricity costs. Setting encodes, moving files around, will also take up some significant amount of time. You will gain maybe 1TB, if compressing audio to opus as well, less than that you will have significant video quality losses. 1TB of hdd space is worth $15 these days. And you don’t waste time/electricity+money/video quality.
So it’s only worth to get existing published encodes of the material you own, of if you are planning on publishing yourself. Or just for fun, if you want to experiment and encode one movie to see what’s the best you can get out of av1.

What about
#!/bin/bash
find . -type f -name '*.mp4' -exec sh -c 'ffmpeg -i "$0" -c:v libx265 "${0%.mp4}-conv.mp4""' {} \;
Kind of. But this is encoded using CPU and will be time consuming. Search for FFMPEG GPU acceleration. The installation (building) will take some time but the time saved during mass conversion of videos will be worth it. I believe FFMPEG supports RCOM on Amd and Cuda on Nvidia . So any gpu should be fine.
I generally think that for storage/archiving you should use CPU encoding and only use GPU for things like transcoding where real-time results are crucial.
GPU encoding is a lot worse quality than CPU, and you can’t change the settings to what you want. Better to just accept the extra time requirement to get a better result.
This. Also unless you have raw BluRay sources recompressing already compressed video isn’t exactly a great idea either way. The space savings will never be worth the loss in visual quality. If you were to retain the quality the space used would probably be similar even with a more efficient / newer codec.
That looks promising. Just keep in mind that this will take a very long time to run. I believe there is a *arr out there that can manage this / show progress, but the name escapes me
Or use A FFMPEG script to sort all the x264 videos and keep it in a separate folder and use handbrake with GPU and mass convert all the videos in that particular folder. AV1 is also good but as some other user said, your hardware needs to support it.
Just keep in mind you’re going to lose quality. Any time you compress something in a lossy format is going to get worse.
Another note, if you’re not worried about quality loss, you might look into AV1 over h265. Much better compression. Though, that might not work with your setup.
Short answer yes. Much longer. More complex answer. Mostly. If you’re planning on your devices being able to support hardware decoding and large resolutions/ high frame rates. Sit-top boxes and appliances are not quite there right now. I believe the newer Chromecast HD absolutely supports av1. But most of the older Chromecast including Chromecast TV do not support it directly. So it will have to be re-encoded to be streamed.
That said, the codec itself is fantastic. As an example for animated content, especially. I have some super high quality rips of the old old cartoon from the '80s of the Ghostbusters franchise. We’re talking nearly a gigabyte encoded in h264 for a 22 minute episode. At SD resolution. Upscaling them to 720p and encoding them with av1. And a constant rate factor of about 40. They’ve been coming in between 80 and 200 MB in episode depending upon how much movement there is etc. The one thing with av1 is That as it degrades it sort of smooths everything which works out perfectly for animation most of the time. It can work for live action etc. As well. But you will encounter smoothing as detail is lost. But overall, it is much more preferable to the H style codex so far
I use a handbrake container and a watch folder. Just move what you want converted to the watch folder and handbrake does the rest.
