Help needed for converting MKV to MKV From FormatProfile5.1 to 4.1

[y0ush4]

i want to convert the movie which has FORMAT_PROFILE 5.1 which is unable to play in my samsung LED tv (UA40-C5000)

i have readed a lots of material and tried lots of thing but i can not convert the video EVEN TO MKV format without the loss of video quality

i just want to change the profile to low


what i have tried yet is as the video have dual audio i used

mkxtoolnix

mkvextract to extract the video (but here is the problem video lost its colours and it seems like burns when extracted to *.h264)

can it be possible to extract a video without quality loss just extract? i have tried TSMUX also which even cant load the video

[y0ush4]

For the time being i have solved the problem by converting it to AVI but still one problem remains it shorter down the SCREEN ACTUAL VEIW WITH BIG BLACK BARS at the upper and lower corner of the screen resulting into shorter view


how can i avoid it?

Have you tried ripbot?

[y0ush4]

Ripbot for the FORMAT_PROFILE problem? or The avi blackbar problem?

You usually can't change the profile without re-encoding (quality loss if using lossy format) . You can change the header to say L4.1, but if the actual contents still conform to L5.1, it still won't work on your player

If the actual contents aren't L5.1 then you can try this ffmpeg patched build:

You can use mkvextract , but you have to put the .h264 or .264 stream (elementary stream) into a container (mkv, m2ts, mp4, etc..). Most players cannot play elementary streams

actually i have tried mkvextract the problem is when extracted it gives me 3 tracks 1 for video(track1.h264) and 2 for audio (audio1.ac3 and audio2.ac3)as its dual audio but *.h264 loss the quality its shows colour burns so my problem is i cant extract the video anyhow

and how can i know if my video is actually l5.1?

for example the screenshot below AVTAAR is playable without any problem But Titanic is not

There is no quality loss when you extract it . The problem is you're playing an elementary stream , and most players cannot handle it so you see artifacts. Put it into a container like m2ts or mkv then try it again.

You need a stream analyzer e.g. elecard streameye , but it' s a pointless exercise . You can try the ffmpeg build, and if it doesn't work, you have to re-encode it anyway

It's actually more complicated than that , some devices need proper buffer (HRD) values , so you probably have to re-encode anyway . You were assuming "L5.1" was the only thing causing your playback issues, when in reality there are many more things that can cause playback problems on devices

For example, for blu-ray compliant devices, you usually have to add black bars to 1280x720 , to keep the aspect ratio (the movie is ~2.35 AR) . The video you have is cropped, so you usally have to add the borders back

Perfect

it was a problem of elementary stream i made the MKV with one audio only and its running fine in PC (VLC PLAYER) without any problem and Blackbars

Now i will try to change the format profile and Run in my LED TV and surly post results

Thanks for the help

The Xbox 360 has a similar problem in that the highest supported level is 4.1. XenonMKV remuxes an H.264 MKV into a MP4 container while changing the level to 4.1. (no video recoding involved) the downside is that you lose any 5.1 channel audio as it recodes the audio to AAC-LC 2 channel Dolby Surround.

If you want to keep any 5.1 audio, you could maybe try running the MKV through XenonMKV and then use that video track to replace the one in the original MKV.

My problem is almost solved Now i can play the movie on my LED TV without quality loss But one thing i lost is audio LIPSYNC around a 10 sec delay in voice

it sux

Anything to fix it?

[y0ush4]

Anyone please?

[Baldrick]

Almost solved HOW? What did you do?

[y0ush4]

Used TSMUX TO demux and selected 4.1 without anything else change(remove all ticks) and Merged it again with MKVmerge

its now playing on my LED TV just with bad lipsync

[y0ush4]

Some words on the LIPSYNC thing?
