Is there a simple (or recommended) way to tag video files according to technical category? I am looking for a method to have a filter criterion between bluray vs 4KUHD vs DVD vs various mobile videos etc. My primary need is to distinguish 4kUHD from BR. I looked through the metadata list, and did not find anything. Could it be possible to add colour depth 8/10bit?

This has become more of a need after I started buying 4K UHD's. We play video on different places in the house and on mobiles, but only the home theater is equipped to tone map UHD, and it would be nice to filter these movies out or at least tag them for all users to know.

You said you looked through the metadata list. Have you looked at the Dimensions field?

Unlike some Media Players MC not only allows you to use the tags it already knows about in a way that satisfies your personal requirements it also allows you to add your own tags.

One way of being able to distinguish between 4kUHD and BR would be to add that distinguishing info to one of the tags Video Files already uses in a way that does not prevent an Internet Search for additional information failing.
A second way would be to look for a suitable existing tag/field that none of the other existing media types in your Media Collection uses and repurpose it.
The 3rd way is to Add a suitably named New Tag.

All 3 methods will work if it is MC that is controlling the streaming to your other devices, but the 2nd and 3rd options may will not work if the decision about what to stream is being made by the "receiving device".

Bummer, actually I didn't think of that  Was too occupied focussing on colour bit depth could do the job.

Thanks!

I have created new calculated field [Definition] which return 4K, 1080p, 720p, 576p, 480p depending on width and on SD depending on framerate to separate PAL and NTSC

Code: [Select]

IfElse(IsEqual([Width],1920,5),4K,IsEqual([Width],1360,5),1080p,IsEqual([Width],888,5),720p,IsEqual(Replace([FPS],/,,.),25,2),576p,1,480p)

Glad to help...

WOW,
This is just great, thank you for this expression!

[wer]

Code: [Select]

IfElse(IsEqual([Width],1920,5),4K,IsEqual([Width],1360,5),1080p,IsEqual([Width],888,5),720p,IsEqual(Replace([FPS],/,,.),25,2),576p,1,480p)
If you're interested in it arcspin, this expression can be simplified in a couple of ways to make it easier to read, especially by using [Height] instead of [Width].

One way is to use the new IfCase function, so that you don't have to keep writing the IsEqual expression:

Code: [Select]

IfCase([Height],2,2160,4K,1080,1080p,720,720p,576,576p,480,480p)
But since the output desired is so simple, and the function assumes progressive, instead of testing for progressive vs interlaced, then it can actually be simplified even further.  Except for outputting 2160p instead of 4K, this gives equivalent results:

Code: [Select]

[Height]p
I don't think it can be simplified further than that...

[lepa]

Except if you have re-encoded and cropped your videos then using height becomes more unreliable as mostly it is height which is trimmed...

[Hendrik]

If you want something thats very reliable, you would likely have to check both Width and Height. Height can change when a video is cropped, and Width can vary based on aspect ratio. eg. an old 4:3 movie in 720p can be 960x720

That's true.
However my definition expression determines video as 720p if video width more than it would be for SD video so it works for me, I don't dare to say every time but I haven't noticed any glitches 'till today. That doesn't mean there aren't 

[wer]

I don't crop and reencode my videos, so it's not an issue for me.

But if one were going to do that, for maximum accuracy one would need to store the original pre-crop resolution in a separate field.  Cropping/resizing/transcoding could do anything.

[lepa]

Well, If I re-encode 1920x1080 video to 1920x800 because I trimmed black bars out, I still consider it as a 1080p video in my library. Reasoning being that it cannot be shown on "hd ready" TV at full its resolution. Not that I have such TV 

But if I do other than just crop black bars and resize the picture then of course definition for that new video should be different like 720p when resized to e.g. 1280x544

But enough off topic from me. Sorry about that

If you consider cases where videos were re-encoded, this could happen:

960x720 -> 4:3 720p
1024x576 -> 16:9 PAL SD

Obviously PAL SD is always originally 720x576 and if it needs to be 16:9 then its anamorphic, but if some player or device doesn't like anamorphic, the result of a scale to get rid of it would be that resolution.
Its a bit of a contrived example, but it definitely happened before, which is why in code when I need to "guess" a "definition", i use H > 576 or W > 1024 to make it  "HD", and not just one of them.

[lepa]

1024x576 would break and yes I have 4 videos from national broadcasting streaming service which has encoded 16/9 SD into that resolution so that is one case where expression fails.

Now that you mention it I think that I did notice it also before but didn't bother complicate things for couple of movies sake. Now that we have Or() function it is though easy to fix

Code: [Select]

IfElse(Compare([Width],>,1920),4K,Compare([Width],>,1360),1080p,Or(Compare([Width],>,1024),Compare([Height],>,576)),720p,Compare(Left([FPS],2),=,25),576p,1,480p)
