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:

* 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

Try this one:

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 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.

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.
