Ridiculously Low 4k File Size

[newcbomb]

I have a 27GB MKV (37 mbps) of The Greatest Showman on my Plex Server. I just transcoded it to H264 MP4. It is now 6.22GB and has a bitrate of 8mbps. Does this seem right? Or did I mess something up? It looks good to me but I only have a 1080p monitor.

 

Thanks

How did you transcode it? What settings?

 

8mbit is low for 4k. You sure you didn't convert it to 1080p?

Encoded it using handbrake? Just set the constant quality to 24 and you should be good to go between quality/file size.

 

My 4k gameplay renders out to like 50+GBs for an hour of footage, compresses down to about 7-8GBs and still looks fine

8mbps is low even for 1080p. And Plex isn't a particularly great way to transcode video. You took an h.265 4K file and transcoded it into an h.264 file with 4.6 times less bitrate. than means a 9.2 times loss in quality. Add on top of that the noise from a bad transcoder like Plex and you easily got 10 times worse video quality. I doubt it looks much better than youtube at 720p.

It wasnt plex it was handbrake. And most of my 1080p movies are 3mbit.

 

Here are the settings

Ok Handbrake is at least a good transcoding software, but I cringed when I saw those settings. You're pretty much destroying any detail there ever was on those movies. and outputting to an .mp4 container no less. I don't understand why you're wasting so much CPU time to get useless files out. 

 

You want to be doing something like this: take an h.264 remux or blu ray rip, transcode it to h.265 at anywhere between 15-20 quality (I personally like 18 as a good balance) and you end up with pretty damn good looking 1080p movies at ~5-8GB each.
