1920x 800/808/816 etc Outputted by BD-RB when played fills the complete screen without anybars.
1920x 800/808/816 etc uncropped to 1920x1080 by uncropmkv has horizontal bars.

There is a way to do the 1920x1080 video before cropped video trick without re-encoding in TSMuxer.

Cool ... what is it?

thx

So either video is cut off on the sides of the BD-RB output or everything looks tall and skinny, do you know which one?

TSMuxer is the muxer used in BD-RB and popBD

hmmm... this is where it gets confusing!
some of the BD-RB movies look fine and a few look tall and skinny.
I thought if its 1.85 then it should look normal and be full screen?
Is it when theres some other ratio like 2.35 etc that these issues come up? If so then I would think that uncropmkv will give the truest results for ratios other than 1.85?

I can't understand how BD-RB can output weird AR if you're using it to backup a Blu-ray disc.

If you're trying to feed it with something else (your own MKV files/encodes "converted" to blu-ray like structure) - the problem is with you.

uncropMKV is really-really simple tool and just adds borders/changes AR - nothing else.

You are always safer with a 1920x1080, 1440x1080, 1280x720, 720x576 or 720x480 video file with borders if needed.

Hello, I have a .mkv container with following basics:

VIDEO RESOLUTION: 1080p ( 1920x816)
.. VIDEO CONTAINER: Matroska ( MKV )
.. VIDEO BITRATE: 10100

.. AUDIO 1: German DTS 786kbps
.. AUDIO 2: /

.. SUB 1: German Forced

I tried a lot of time to uncrop this fil, but always the final file is async of 10 seconds. The original file is OK!

Do somebody have a solution for me, please?

Just for Info: All Tools are installed correctly.

Thx

It is possible that there is audio delay, which is not handled properly by uncropMKV (it still uses mkvinfo, not mediainfo).

Can you check what mediainfo reports about your original file?

[canarias]

Mediainfo:

[08:54:34] Detected video: ID#1:V_MPEG4/ISO/AVC:1920x816 23.976fps (AR:2.35)
[08:54:34] Video height not compliant (480/576/720/1080)!
[08:54:34] Detected audio: ID#2:A_DTS:audio (48000Hz/6ch) Language: ger
[08:54:34] Detected subtitles: ID#3:S_TEXT/UTF8 Language: ger

greets

This is not mediainfo
You'll find mediainfo.exe in tools folder.

Hi,

I have been using uncropMKV for some time now and it is a great product.

But...some videos (1920x800, 1920x816, etc.) are not getting uncropped.

When I run uncropMKV the program processes the video at 36.xx fps, well beyond the 23.976 fps of the movie. The time to completion is about 1 hour and the filesize is about 16-20% of the original.

Normally, the fps is around 7-10 when the program is actually uncropping the video and takes about 5 hours to complete.

For some movies I have used an earlier version which has worked fine.

I am now faced with a situation where ver.05 nor ver.08 does not uncrop the moview (1920x800).

I have downloaded the complete uncropMKV package. I uninstalled ffdshow and reinstalled it, making no changes to the configuration.

I have even tried using MKVextract and MKV merge to remake the MKV file, still with no success.

In version .08, I have also tried 2-pass, which has worked in the past.

Note: the movie does play in MKV form and when exploded to BD file form (*.m2ts file).

I am beginning to think the problem lies with the other programs in the package. I say this because one video would not uncrop in v.08, but would in ver.05.

Any suggestions?

Thanks,
Gary

Hi!

I am now faced with a situation where ver.05 nor ver.08 does not uncrop the moview (1920x800).

Based on your stated resolution (of a movie), it would appear that your original source material was eihter a BluRay disc or an HD-DVD disc - both of which would have original resolution of true 1080p or 1080i.

If so, why would you first create an MKV with a cropped resolution of 1920x800 (rather than 1920x1080) - and then try using "UncropMKV" to return to the priginal resolution?

[deank]

Nothing in the encoding/processing is changed in uncropMKV. If it stopped working - the cause is at your side.

Hi ...

Is there anyway to have the output from uncropmkv be made to fit DVD5, DVD9 etc. by altering the bitrate?

Popbd is fine if you want to span multiple disks but my inclination is to use just 1 DVD9 unless the bitrate is to slow.


thx

i can input bunch of mkvs into it,and software will check automaticly the file is 1080 or 720,if it fits,leave it.if not,uncrop it to the right size,and replace the old file with old name,and delete the old file. sorry about bad english,hope you can understand it.

It is a notice from tsMuxeR of how final m2ts stream will be constructed, based on the b-frames presence.
