Hi everybody,

Recently I found the way to make AVCHD out of .mkv files, in order to play HD movies on my PS3.
So, as you described many times in prior posts, I use mkvextract to obtain the .h264, .ac3 files out of a .mkv, then I run h264info to change the level to 4.1 and finally I use tsmuxer to create a Blu-ray structure (note: I also insert a .srt file, with subtitles for my language - not English :p ).

My question is if anyone knows how to proceed with output files bigger than 4.7 GB. I know tsmuxer has the ability to split files, but I have seen the following result:

Have a let's say 6 GB .h264 and it's equivalent .ac3 file and .srt file, load them in tsmuxer, choose to split at 4 gb -> the output is a blu-ray structure, with the folders BMDV and CERTIFICATE, and in BMDV/STREAM/ i have 2 files - let's say xxxx.m2ts and yyyy.m2ts.

My question (boy, I thought i won't stop writing) is:
Is there any way to write this on 2x 4.7gb DVDs ?

Thank you for your time,
Stef

mkv2vob converted file playing in 4:3 on PS3


I have a 1440x1080 video here with 640K 5.1 (which needs to be intact in the final product). It was originally perfect widescreen but now when I convert it for PS3 it plays in a 4:3 area only. Really irritating, this is the first video that has done this. It plays in VLC wrong too. But the original mkv file plays perfectly (on the computer). So it's something mkv2vob is doing. But there are pretty much no options as far as aspect ratio goes in that.

Any help would be greatly appreciated!

Stef, you're going at it the old way. tsMuxeR has come along way since this post started. Here's the easiest way to get your 6GB movie on two DVD5s.

First of all make sure you have the latest version of tsMuxeR. There is a link for it in this thread.

http://forums.afterdawn.com/thread_view.cfm/639346

1. Load your mkv directly in to tsMuxeR.

2. tsMuxeR now has the ability to change the AVC level, so now we can leave out the h264info step. Highlight the video stream, check the "change AVC level" box and change it to 4.1.

3. Split the output file in tsMuxeR to whatever file size you choose, obviously do not go bigger than 4.3GB.

4. Select m2ts as the output file type and start muxing.

Now you should have two m2ts files. Load one m2ts file in tsMuxeR, select Blu-Ray as the output (Blu-Ray is needed for subtitle suppport). There is no need to change the AVC level here as it was already done earler. Repeat for the other m2ts file.

Now you can burn using whichever app you please, make sure you burn to the UDF 2.5 file system.

Done!

Hi Odin, thank you so much for the reply.

Yes, I am aware of newer releases, and I know TS muxer can change to 4.1, however I was doing it the "old" way cause I heard that sometimes the new way is not successful.

I understand the way you suggest, but I have another question.
Let's say I have a 1.mkv file, and a 1.srt file. If I split 1.mkv to A.m2ts and B.m2ts, how should I proceed with the 1.srt when creating blu-ray structure from A and B ? can I use the same subtitle, or do I have to split it also ?

Thanks,
Stef

When you remux the whole .mkv to one .m2ts, then split the .m2ts to two files the .srt will split with it. When going from the first disc to the next the subs should pick up where it left off.

As for the unsuccessful attempts using tsMuxeR it is because the h264 video stream was recoded outside of Blu-Ray compliancy, if it does not work for tsMuxeR it will not work for mkv2vob either. These are usually 1920x1080p movies.

Hi,

I've been using tsMuxer and MKV2VOB since they came out to transfer movies to my PS3 over ethernet from my computer. I had no problems until I encountered MKV files that had subtitles....

This has proven to be a major pain in the arse. As I understand it is not possible to hardcode the subs into the HD vob file and display them on the PS3. Can someone confirm whether this is the case?

I know that it possible to add them into a Bluray structure using tsMuxer but I would like to stream the movies rather than burn them onto discs. Surely the PS3 would add the ability to display these subtitles in a near-future firmware update?

Thanks for your help

You can hardcode the subs, but you'll have to re-encode the video. You can use MKV2VOB to do this, or there is an alternative method using MeGUI and AviSynth.

As to future subtitle support, let's hope so, most of the time you have to hardcode the subs because your video source is not the exact AVCHD compliant 1920x1080 or 1280x720 resolution. And hopefully they bring out support for DTS and other HD audio codecs...

Thanks for that. I knew about the MKV2VOB ability to re-encode the subs into an MPEG2 file. I tried it once and was not overly impressed with the results. Could you point me in a direction of a guide on how to do the subs in MeGUI? I haven't had much experience with AviSynth though.

Thanks

Has anyone actually tried this? I thought subs were not supported with .m2ts and the only way is to hardcode them.

You are correct, subs in the m2ts alone are not compatible. Once the whole m2ts file (with subs in it) was split to two new m2ts files those would need to be remuxed to Blu-Ray structure. I was offering a way to split the subfile.

Hi Odin, I have one more question.

So I should make a big m2ts file out of my big mkv, but with what tool should I split the m2ts to smaller m2ts files? By using tsmuxer?

Thanks!

Hello,
Thanks for the great thread. I have read through it over the past weeks and had much success getting ps3 compatible video from mkv files using tsmuxer to convert to m2ts. I now have tried the more advanced methods to attempt to convert a 1080p dts mkv source to avchd which I'd like to play from an external HD. Using the information in this thread I was able to convert the video into something that is ps3 compliant:
1) tsmuxer to extract dts audio and 1080p video streams
2) megui, using rye's bluray profile, adding proper number of lines, changing number of ref frames from 5 to 4, etc.
3) tsmuxer to recombine the audio with the video from step 2 into bluray structure. Rename file structure to create AVCHD split into 4 Gig segments

My problem is that when I try to play off the external HD is that I get beautiful video, but no audio. Audio stream by itself plays fine in vlc.

Any ideas?
Thanks in advance!
Forza Italia!

You're on the right track. This can all be done in one step.

1. Load your mkv with the subs.
2. Highlight the video stream and set the AVC level from 5.1 to 4.1 if neccesary.
3. Set the output format to m2ts
4. Go to the Split & Cut tab, choose split by size and split down the middle, i.e. if your mkv is 6GB split it at 3GB.
5. Start muxing

Please note that I have never had the need to do this, so I have never actually done it. Let me know how it turns out.

Go here and read about a useful application I use for verifying movies with subs. It's real easy to use.

The two most common reasons for this is;

1. The AVC level is higher than 4.1, tsMuxeR can change this... you just have to tell it to.

2. Most commonly with 1080p rips there is too many reference frames, b-frames/b-pyramid which exceed Blu-Ray compliancy. Most of the rips that you would download were not ripped with Blu-Ray playback in mind. The only way to fix this is to recode.

Hope this helps.
PS, glad to hear your subtitle issues are resolved.
