Sickbeard Help

[kirshman 1]

Hello everyone.  I have been using cayars script for awhile now, but wanted to give sickbeard a change.  I ran it on a few different videos now, and they all look a little washed out as you can see below.  Can anyone tell me what setting would be causing it to do this?  This is vlc running the videos side by side.  the one on the left is the orignal mkv ripped from the 4k, and the one on the right is the converted mp4 from sickbeard. I'll also include part of my config script so you can see.

You don't want to convert from 4K to 1080 as you're not handling the color conversion..

You would want to source a quality 1080p version before converting it to a lower bitrate streaming version so there is no color space issues. 

[kirshman 1]

Thanks for the help.  Sorry, I don't understand this script enough to understand where it says it's changing to 1080p.  Is it possible to just leave it at 4k?  How would I go about that? Or is the a different converter I need to use?

You would not use it on 4K material.  It's meant for 1080 and lower as uses "normal" color spaces.

Is there something else you'd recommend to convert 4k then?

HDR to SDR conversion is not an easy task, if it were, Emby would do it when transcoding, but it isn't. SDR raw material always will look better than HDR to SDR converted material.

Is there a tool to use when just trying to make the files smaller then?  The mkv off the disk is about 50gig.  I'd like to compress them for smaller size.  Is this doable or should I just stick with 1080p?

You can try UHD ripper from DVDfab, it even supports HDR to SDR conversion, but if disk space matters, you'd better stay at 1080p.

If you want a 1080p version IMHO start with a 1080p version but not a 4K version.  The difference in processing needed is crazy different as well as results usually.

That's why most of us who do 4K have two different SOURCED files to work with. They are NOT mastered from the same file.

[kirshman 1]

I follow you.  But when you say you work with 4k what are you meaning?  Just playing them as full sized files, or can you compress them a little and keep the 4k standard the same way you could with 1080p?  I'm not trying to get them to 1080p just a smaller file size not lower resolution.

To rewind a bit - what is the goal here ?  What are you trying to achieve ?

 

[vdatanet 1617]

Yes, you can. UHD remux is about 50 Gb and this UHD rip is about 10 Gb, and it's much better than 1080p.

We'll, my first question was answered and I get that you shouldnt try and convert a 4k file down to a 1080p. I didn't realize that's what the sickbeard was doing and I appreciate the help.  Now I'd like to know how I can take the 4k file and just make the file size smaller while keeping 4k resolution.  Cayars script would take a 1080p mkv that was usually around 30 gig and change it to a roughly 8 gig 1080p mp4. I'd like to know if there is a way to do the same but keeping everything 4k.

If you own the original UHD Blu-ray, you can rip it reencoding the video with HDR passthrough, I don't know If that can be done converting the file.

That's awesome.  What did you use to get that ?

What programs would do this?

[vdatanet 1617]

DVDfab, UHD ripper module.

[Carlo 4561]

I could probably add to the script to handle this or better yet just make a 4K version. I never really even thought about doing it to be honest because of the way most of us use Emby.

For example I have a 4K library and only share it with members in my house and they know only to use it on the property (house, garage, work shop, pond area, screen porch, etc). For these 4K movies it's all about QUALITY and they are pure rips with no conversions done at all.

Now in my normal movie library I'll have 1080p versions that have ran through the scripts and have been compressed, have 2 channel AAC audio ADDED when needed and produce files that will pay back on any device (as long a bitrate not exceeded).

So 4K is for in house viewing where quality trumps size and bitrate doesn't matter.  Normal library is designed for good quality 1080 that will direct play anywhere.

Thus I've never worried about trying to compress 4K.
Make sense?

ok - but so you can 'stream' it (so you have bandwidth limits?) or you have storage limitations ?  Are you playing it back on a large screen 4K TV ?

Knowing the target will allow us to suggest the best solution for you - but in summary, currently, converting a proper 4K blu-ray to 'anything' is intensive and unless you know what you are doing, likely problematic.  As @cayars has said, it is usually much better to get the source material in the standard you need.

And that's probably the best way to do it if you're going to.  Are you using a GPU for the conversion or just CPU?
How long for a typical movie conversion?
What type of size difference are you seeing?

Yep.  Makes perfect sense.  Thanks!

Yep I play on a 70 inch 4k tv.  Not huge but nice.  I just like to save space on my drive which is why I like the file sizes smaller.  I converted my tv and movie collection from DVDs and blurays a couple years ago and now as I buy it's more and more 4k content.  It's from my own disks not downloaded files, that's why I have been ripping and converting.

I'm using GPU for the conversion (Nvidia Cuda), It takes 2-3 hours (or more, I did that some time ago) using Nvidia GTX1060 and the size is about 1/5. Using a 55", I don't appreciate quality differences. Too much time for me, I prefer a UHD remux without conversion.

Same.  Maybe when/if GPU conversion of these files gets faster and can process a 4K disc in a hour I'll consider it again.  Never know what the future holds.  Besides then I'll likely be playing 8K and the 4K will be "so yesterday". LOL
