Worth re-encoding in H265?

[stonesfan99]

Hello all, I have a very large collection that is ripped and converted to smaller .mkv files. All of my files are encoded in H264 typically with AC3 audio. Is it worth the time to re-rip everything (around 350 files) and encoding them to H265? My machine uses an AMD Ryzen 7 1800X (no overclock) with a pretty decent Noctua cooler. Mainly I am concerned with how long such an encode would take. Currently I can usually convert a 2hr long file in around an hour using the default settings in BD Rebuilder with the MKV, 1920x1080, 640 DD 5.1 profile. My playback equipment is an Xbox One S which supports both H264 and H265-encoded files. Thanks.

What's the point? They'll never look as good as what you have now. You're willing to degrade the video quality just to make the files smaller?

Why don't you try it and find out?

What graphics card do you have? Try the GPU encoder and see how the speed/quality compares.

So you want to go back to the source, re-rip, and re-encode. If you can do realtime encoding of h265, that's something like 3 month's worth working 8 hours a day, assuming 350x 2 hour movies.
Assuming also that same amount, storage-wise, would at 5Mbps use up 1.5TB, it is just ~$65 to get a drive to store that, or if you are already using double that with h264 files, $65 is all you would be saving. And that's not counting the cost of your time & electricity.
Me, it would not be worth it.

Are you thinking his source is the Blu-Ray? I'm thinking it's not, but some downloaded MKV someone else already reencoded. The reason I think this is:

That tells me his 'source' is an already degraded reencode from the Blu-Ray. But I could easily be wrong about that and perhaps stonesfan99 will set me straight.

He did say "rip" so I took it at face value, but you've got a point.

2TB drives are available for $40 or less, with larger drives available at the current $20/TB mark.

So savings are just over $1 less electricity, wear and loss of productivity per computer hour.

Edit: Oops...brain fart! ~.06 cents per computer hour less all the other stuff!

not worth it reencoding
