uncropMKV - get your video files to AVCHD/BD compliant resolution/level/ref frames

[deank]

There is an "uncrop"/"re-encode" function in multiAVCHD which is much better than the standalone uncropMKV application.

I strongly suggest that all who are aiming at proper AVCHD/BD playback/compatibility to use multiAVCHD, instead of uncropMKV.

uncropMKV is now updated to ver 1.2: (http://multiAVCHD.deanbg.com/uncropMKV/)

* Added 1 pass / 2 pass HQ/VHQ options, similar to those in multiAVCHD
* Fixes and compatibility improvements

What setting do you prefer for quality and speed ? But size doesn't matter.

I tried 1pass VHQ on movie. It takes 30 hours on my Amd quad core.

Are there any significant differences between 1pass and 1pass VHQ ?

Thanks

[deank]

Good choices are 1 pass and 2 pass (the normal ones). If you do not care about the size - use 1 pass.

Hey Dean,
I was using uncropmkv with x64 support. With exchanging only x264.exe files. But now I can't do that. It's not working anymore. Can you help me to make it x64 ?
I'm using Windows xp x64.

Thanks

[deank]

Why is it not working? Just try to find a proper build and test... There is nothing changed there...

[champion]

what is mx264.exe ? Do I need to change this file also ?

[deank]

No, do not touch it... It is for multiAVCHD, not for uncropMKV.

[champion]

Am I doing something wrong ? I downloaded x264.exe from http://x264.nl/ and copied to /multiavchd/tools/ folder then I'm running uncrop application and the preview screen still blank. When i put your x264.exe file everythings fine. Could you help to find proper x264 for x64 please ?

thanks

[deank]

Try this one:

nope. it's not working.

Version 1.4:

A bug was fixed, causing video to be cut improperly at the end (resulting in 1 to 30 seconds missing from the end of the video).

You can download the .exe only from this link (http://multiavchd.deanbg.com/uncropMKV.exe) and replace yours.

Hi deank,

I have some MKV with a 24.000fps framerate (I get this info from mediainfo). With my media player (popcorn C-200) this framerate it's a problem (glitch) at this moment (he's play correctly MKV, without any glitch, with 23.976 framerate).

These mkv have 1 video track, 1 audio track and 1 subtitle: to change framerate can I use uncropmkv?

I think subtitle track must be adjusted manually (I must to extract subtitle track and change framerate to 23.976 and then remuxing).

TIA

[deank]

Yes, you can use uncropMKV... I guess subtitles will need really small adjustment (it at all) if your video is 2-3 hours long.

edit: I think it will be easier to use eac3to slowdown and tsMuxeR to remux with the new fps instead of reencoding the whole movie.

Hi. Here is a question.

I have an mkv file with a video resolution of 1280x534. See, the aspect ratio of the video is 21:9. So, instead of using the standard 1280x720 resolution and put black bars on top and bottom, the author of the video decided to use this resolution.

- Can uncropMKV add the black bars on top and bottom and make it a 1280x720 vid? (not strech it)

- Can uncropMKV add the black bars without re-encoding the rest of the picture?

Thanks,
kurkosdr

[deank]

1) Yes, that's what uncropMKV does
2) No, full reencode is required.

I used a similar method: I use besweet to change audio from 24.000fps to 23.976, Subtitle workshop to change subtitle framerate and finally Tsmuxer to remux with 23.976 video framerate: works perfectly.

[kurkosdr]

1) Yes, that's what uncropMKV does

Any instructions in order not to lose quality?

[deank]

You always lose quality when re-encode. Just give it a try with 1 pass turbo and 2 pass fast and try to find the differences yourself.

Dean,

First of all, many thanks for all the excellent tools you have out there. I use a lot UncropMKV (from the MultiAVCHD install version 1.55 )on the MKV files in order to make them AVCHD compliant (I use MKV2VOB afterwards to make the AVCHD's.

This process works really well and I have used it already dozens of times, unfortunately with the latest file I have MacGruber (2010) 1080P.X264.NL.SUBBED.Bradje.mkv the audio is not in sync anymore with the video.

Here is the input when loading the file into uncropmkv :

[17:56:22] Detected audio: ID#2:A_AC3 (48000Hz/6ch) Language: eng
[17:56:22] Detected audio: ID#3:A_DTS (48000Hz/6ch) Language: eng
[17:56:22] Detected subtitles: ID#4:SRT Language: dut
[17:56:22] Detected video: ID#1:V_MPEG4/ISO/AVC:1920x800 23.976fps (AR:2.4)
[17:56:22] Video height not compliant (480/576/720/1080)!

Nothing special as you can see.
Is there anything special I need to do?

Many thanks.

[mpucoder]

Is there anything special I need to do?

Read the forum rules, especially rule #6. The name of the file implies a downloaded or "shared" file, and the non-compliant resolution confirms that this is not a file you ripped from a BD.

[italoparty]

thank you for program....
when try to uncrop (ver. 1.55) file i had a massage "hx264 had stop working", im runing on win7 64bit, but on other computer (with same file) on winxp everything is ok....
i try to reinstali and install every codec, run as administrator, but nothing.....
thanks for answer...
sorry for bad english....

Hi everyone,

My goal is to burn a couple of mkv files to blu-ray discs. I don't want to change any aspect ratio, I only want to add or subtract to the black bars to make the file's resolution acceptable for the bd format. I already know how to use tsmuxer and imgburn to make a bd disc out of an mkv that is already the correct resolution.

So, if I have an mkv that is 1920 x 816 and I want to make it 1920 x 1080, do I set "Resize" to 1920 x 816 No Resize, or should I choose the second 1920 x 816 that doesn't say No Resize?
Also, "Uncrop to" only has 1920 x 1080 as a choice, I assume that's right?
Do I leave "Crop T/B" at zero?
What is the highest quality setting, 2 pass VHQ? I want the highest quality, and I'm not concerned about file size or the time it will take.

Thank you in advance for your help! And thanks to Dean for a wikkid good tool!

[mpucoder]

You should probably start with the video from the BD itself, not a cropped or resized source.

I posted this to Deans own forum but I think this may be more readers here....

I set an mkv video file to be "uncropped" with uncropmkv version 1.55.

It successfully produced the *.264 file but mkvmerge failed to mux the file resulting in the *-uncropped.mkv file having a byte count of 6 bytes, even though uncropmkv said it was successful.

I did some investigation and found the version of mkvmerge used in the uncropmkv 1.55 package as being 2.5.3.0. In a recently installed mkvtoolnix package I found mkvmerge version 4.4.4.0.

Using the more recent version of mkvmerge with uncropmkv 1.55 I found the the file muxed successfully.

Is there any reason why the older version of mkvmerge is included in the uncropmkv 1.55 package or can the old version be substituted with the new version without problems?
thanks
Barry

@bamsebo

Hi! Is there any reason why the older version of mkvmerge is included in the uncropmkv 1.55 packageProbably because Dean incorporated his "uncrop" tool into multiAVCHD quite some time ago - so that there was no reason/need to update the standalone version...

[sith7]

Hi. First time posting here. I've downloaded and used AVCHD and uncropMKV and love them both. Great tools. HOWEVER, lately I'm having a problem with uncropMKV. When I start to extract an MKV to 1920x1080 the process only get to about 3%, then opens the project for writing. So I keep ending up with a 5 min portion of a full film. I've uninstalled and re-installed, both full version and the one with AVCHD but with no luck. It just doesn't work anymore with any files I try. Any suggestions as to what may be causing this?

[stinman]

well as I read through this it seems that a re-encoding of the mkv is done to add the borders back from a 1920 x 800 to 1920 x 1080.Can't the clip ini just be changed in a hex editor and not re-encode the encoded mkv bluray movie? Seems I read that some where. When you have a 1920 x 800 BD burned on a disk the Bluray player stretches out the video.Makes their heads look long.The more times you encode a movie the more compression artifact you will see in dark scenes and such,right?

What kind of bullshit is it when I go to the first page of this post I get a re-direct to multiavchd site with a user name and password pop up.Then says access denied? How does this happen here at doom9 forum deang try to redirect me?

I stumbled upon this nice utility while trying to author some collections - could someone advice on command line usage ? The GUI appears not to have an option for a separate destination dir? Reading from and writing to same dir - not desirable.

I cannot get this to run correctly - I load a mkv file and it indicated the tracks found and the general parameters etc. When I click on queue and then click start, there appears for about a second 2 command prompt windows. The the message Done! appears. The resulting file is 0Kb with the suffix .264.

I cannot get the preview to show also. Any clues please?

Running Windows 7 Professional 32 bit. I have tried compatibility mode XP 3 but no help...

[jaket4570]

This is the same problem I'm having and described in my post
http://forum.doom9.org/showthread.php?t=168055

I failed to mention that my .264 file is also created with zero length. I didn't get any replies to my post - let's see if you have any better luck.

I found a "sort of" workaround. I uninstalled uncropMKV and then installed multiAVCHD as it has uncropMKV within the package. Still no joy running uncrop as a separate program but I can at least add black bars to a non conforming mkv file if I want a AVCHD output.... next stop inspect the registry...

[netmask]

Running UncropMKV from the multiAVCH folder of the fresh new instal resulted in being able to preview M2TS and AVI files. Still no luck with MKV or MPG. I checked several MKV file some with header compression and others without, this made no difference.

So do you know what codec or program UncropMKV uses for it's preview function? Maybe there is a setting to be adjusted?

The preview of the AVI files I loaded didn't get the correct aspect ratio and stretched them to a 3:1 aspect ratio. They were all 16:9 files.

PS BTW nothing wrong with the registry

[golden-berg]

For past month, after running UncropMKV to convert to 1080 or 720, and then using tsMuxer to produce a Blu-Ray (NOT an AVCHD) disc, the following results:
- tsMuxer completes with error "Unsupported media type 15 for AVCHD/Blu-ray muxing"
- resulting folder plays on computer with VLC
- once burned with ImgBurn, will NOT play on BD player Panasonic
All this after working beautifully for years! What's going on?

[netmask]

Solved: MKV not showing in preview.

I tried Codec CodecTweakTool_530 and under Preferred Splitters (86) I ticked the button Haali (recommended). This restored MKV files in the preview mode.

Many thanks for the various suggestions but at the end of the day it was a simple codec problem....

[omegaman7]

There has to be a way to uncrop (resubmit black bars for compliancy), without a lot of cpu overhead, or re-encoding. It's a very basic task for a PC ;) Can't wait til I find the way. It'd save me hours and hours, on reencoding! Once video is m2TS/BD compliant, encoding should not be necessary, only to make room for more video.

Dean,

Great programmes, thank you.

On 5th August 2009 you wrote, "There is an "uncrop"/"re-encode" function in multiAVCHD which is much better than the standalone uncropMKV application. I strongly suggest that all who are aiming at proper AVCHD/BD playback/compatibility to use multiAVCHD, instead of uncropMKV."

Is the output from uncropMKV not as good as multiAVCHD if I just want an uncropped MKV file with quality as high as possible and size not important? What settings would you recommend to achieve this in uncropMKV (for an MKV file) or multiAVCHD (for a blu-ray with no menu)? I'd be very grateful for your advice.
