"Good enough" movie quality

[Baterka]

Hi, I realized that I dont need all my movies 4k or 1080p so I decided to convert them to h265 720p (or for some good movies to 1080p). I have so many Blurays and DVDs on my desk what I just want to throw because I have 8TB NAS.

 

What is "good enough" quality for 720p/1080p? What bitrate and sound quality I should use? I want to save some space but not go under some line where I will say "fuck that compression.

 

My PLEX app saying that best quality is equals to:

480p 1.5Mbps

720p - 4Mbps

1080p - 20Mbps

Its probably for h264 so I want to know what will be similar bitrate for h265.

 

I was always using original sound from DVD bluray to get the "best" but now I wonder if its needed too...

Using handbrake, you can use "constant quality" instead of "constant bitrate". That solves your problem, just run it on a short video and see what settings meet your preferences.

h.265 depending on scene and resolution can have around 30% to 50% lower bitrates at the same quality but the encoding can take a LOT of time

 

You could also look at AV1 which gives the same quality on up to 60% lower bitrates but currently the encoding speed is extremely slow and it will take several times longer to encode than h.265.

More than about encoding speed I care about bitrates what are somehow standardized or widely used. I need to know how much is "enough" to have good experience as a normal person and lower my space consumption

For DVD rips, Handbrakes default quality setting of 22 is already good. I haven't seen any difference between source quality and that. I did some testing with my own 720p recordings few years ago and found that 25 on that scale is lowest I could go before seeing quality loss.

You speaking about h264 or h265

h264. I don't change things that much around.

But who dont want 20-50% smaller files
