Bluray aspect ratio problem

[Michel007]

hello,

I wanna burn blurays (.mkv) on a bd 25gig disc. to watch on a normal bluray player.

I used the tutorial of => (https://www.youtube.com/watch?v=StIIWUuUiwE) and i works good but i have aspect ratio problems.

But when i put the burned disc in my pc the aspect ratio is normal. (the problem is the black bars above and below the movie picture arn't on the normal bluray player, instead on the normal bluray player it is full screen)

and the problem with full screen is that the picture is elongated, so the faces are stretched.

i also tried to configure the settings on the tv and the bluray player but the problem stays (on tv mode zoom ,wide etc ....)

maybe its something with the settings of tsmuxer gui 2.6.12 or mkvmergee

If the display attached to your Blu Ray player is a 16:9 TV, I think you inadvertently cropped the letterboxing from the original 16:9 to 2.4:1 before attempting to burn it back onto the disc. Blu Rays will only work with 16:9 images in HD, it will never add black bars on either the sides or top and bottom, you need to add them yourself before you encode the video.

If that's not it then you haven't provided enough information.

thnx's 4 answering the question,

first of, yes its a 16:9 tv (samsung 55)

and i don't crop nothing of the video file its untouched, and if i play it on my pc it has the normal aspect ratio

Look at it with mediainfo, paste what it says about the video track here.

yep it says 2.40:1 , i have no idea how to change it

[ndjamena]

You re-encode it, adding 140 pixels worth of black bars each on the top and bottom to get it back up to 1920*1080.

Or put it in an MKV and play it via USB.

That's about all you can do.

That is the problem, 1920 x 800 is the aspect ratio of only about 90% of all major movies.

That is a bit too sophisticated for Blu-ray to handle as it expects everything to come in "standard" boxes, yes you would have to add blacks bars above and below to make this 'right' and in 'compliance' with 1920x1080.

I can't but I am sure some posters can 'explain' that this is not a shortcoming but instead a brilliant feature of Blu-ray.

[ndjamena]

To be honest, I'm surprised it didn't just reject the video outright. 1920x800 isn't even a Blu Ray compliant resolution.

Have you ever had a dvd where the aspect ratio in the ifo didn't match the aspect ratio in the stream? Or an MKV with the same problem? Really, Blu Ray HD is 16:9, it either obeys the specs and is predictable or it doesn't and then what?

Except it isn't. The great majority of modern movies are presented FLAT (aka 1.85:1), with only ~25-35% shown as SCOPE (aka 2.35/2.4:1). And that's not counting the legacy films shown in ACADEMY (1.37/1.33:1), which greatly eclipse both the previous numbers. Of course, I'm sure you'll be quick to discount those as being "idiotic", old, and not even worthy of consideration. I mean, who wants to watch such losers as Citizen Kane, Gone With the Wind, Dr. Strangelove, Casablanca, Singing in the Rain. Surely not your kind of smart folk.

Heaven forbid we should rely on the constraints of standards!

The OP's problem is NOT that he can't get Blu-ray to have the "right" AR, or that he has to do extra "work" to shoehorn it into Blu-ray's constraints, but rather he isn't sure which path to take to get something that WAS formatted correctly for Blu-ray to be put BACK onto Blu-ray, given the mangling that has occurred in the intervening period, and the OP isn't fully understanding of how all these things work.

You may be so, but you would be wrong.

By the way Dr. Strangelove is an interesting movie aspect ratio wise.

Of course Kubrick's aspect ratio wishy-washiness is legendary.

And who in his right mind would intend to force a 4:3 aspect ratio on a DVD for a film shot in widescreen? It was either Kurbirck himself or perhaps was it just a sweet white lie of a stuffy old engineer who goofed up?

By the way, it seems that still quite a lot of people prefer 4:3 over widescreen let alone ultrawide, I suppose that way they can have a better look at the actor's teeth when the camera zooms in full frame.

Kubrick wasn't wishy-washy about ANYTHING. He had his preferences, knew the realities and accommodated both.

The solution is simple. Rip your original Blu-Rays again. But I'm guessing that's not an option.

If the OP is willing to go to the time and trouble, unCropMKV may be the simplest way to re-encode non-compliant, cropped MKVs. A slight quality loss will be unavoidable, but might not be noticed.

Otherwise, it's going to be necessary to find another way to play them back. It's been mentioned that some standalone Blu-Ray players will recognize cropped MKVs as-is, whether via USB port or on data discs. Non-compliant Blu-Ray files will not play properly, if at all.

In tutorial you linked it says that you should select Blu-Ray in TSMuxer. Did you try to select M2TS instead of Blu-Ray?
Also, does your Blu-Ray player support any other format like MKV or MP4?
You choose to create Blu-Ray structure but your file is not Blu-Ray compliant. Maybe that confuses your player as Blu-Ray video is always 1920x1080 or at least in 16:9 aspect ratio.

thnx's 4 the response people.

i didn't try the m2ts setting, i was looking for a easy way to download bluray movies and to burn at disc to keep.

but my normal bluray player won't play them normal (aspect ratio) so i find a other way.

i watch them with a mediaplayer iconbit and i stream them for a nas. now im looking to find a mediaplayer where you can install a bluray optical drive into.

but for now i have a external bluray drive with usb to my iconbit and i can watch the movies normal (with bars)

personally i think the problem is something with region settings but thnx's 4 the respons

[ndjamena]

Region? As in planet Earth... reality... You should go visit newpball in whatever fantasy land he resides in.

At most the only black bars a Blu Ray player should ever have to add to a picture are the pillar boxing kind on old 4:3 SD resolutions. BD players are DESIGNED to be played on 16:9 televisions, so for simplicities sake that's all they support. Since it's not expected to ever encounter the situation no-one bothered programming in the ability to add bars to the top and bottom, why would they? Even CRT TVs came in 16:9 and the only way to assure the correct resolution was passed through was to manually set the output AR in the menus.

I've already said, I'm surprise it played it back at all, and all it's really done in your case was treat it like any other 720p/1080p resolution image using whatever criteria was programmed in to identify them, which apparently wasn't all that stringent.

[fritzi93]

Region problem? No. Again, your problem resulted from trying to author non-compliant cropped MKvs to Blu-Ray.

... for now i have a external bluray drive with usb to my iconbit and i can watch the movies normal (with bars).

Then you already have an alternative for playback. If you want to archive the files, burn them as data on a BD25. And why do you think you need to play the files from a BD drive if you have a NAS? Get some hard drives instead.

[Cornucopia]

To amend ndjamena's last post: movies in 1.85:1 or 2.4:1 will have SOME small letterboxing as well, but that should have been left alone too. So, if your previous process was to crop ALL black bars, those will need to be reinstated in order to restore the 16:9 AR required for BD compliance.
