MAF and myself are stumped. I want to watch 720p episodes of Dexter on my TV, but they are in MKV files, always. I can get MKV to transcode-stream to the 360 via media center, but as a side effect the sound is out of sync, making the episodes unwatchable. This is probably because mkv files are shitty container files. I really don't know what to do here. I am pretty sure I was able to convert mkv files using some video apps on the Mac, but I still came up with the same audio sync prob.

Thanks.

I believe we have had a thread on this

Sorry. I might have asked this before actually, some time ago, when I DLed the complete season of a show in mkv by accident. The problem just popped up again with these Dexter episodes, that are only in mkvs for high resolution.

I have been playing the videos on my laptop and using its HDMI port to output the stream to my TV, but this isn't optimum.

no, its a really common problem

anime fansubbers use mkv to prevent their work being sold on ebay for instance

I imagine mkv related tools have come a long way since I tried to demux though

Let me give this a try.

I wonder why Dexter is only available in HD in mkv. Is there something that makes mkv an especially good container for hd content, video or audio, over the other containers?

I think the reason its popular is it can have multiple audio tracks, embedded fonts for the subtitles, chapters and is smaller then .avi for the most part

I believe it does 5.1 audio as well

oh and its open source, internet people love that

I am trying that first link you posted. It is doing its thing now. I will bump this tomorrow to see how it turns out (the file is like 1.5 gigs and I need to get ready for bed).

I'm pretty good at syncing audio and video, so as long as the separation goes cleanly, I should be good.

don't have .mkv file, so see for yourself if it works or not.

ffmpegx is re-encoding the extracted video stream to mpeg4 right now. Once that is ton, I will tr to dub the audio. It's in an ac3 file, which I am not familiar with working with, so I may encode it to something I know.

I wiki'd it and here what It gave me:

Quote

Dolby Digital, or AC-3, is the common version containing up to six discrete channels of sound, with five channels for normal-range speakers (20 Hz – 20,000 Hz) (Right front, Center, Left Front, Right Rear and Left Rear) and one channel (20 Hz – 120 Hz) for the subwoofer driven low frequency effects. mono and stereo modes are supported, as well. AC-3 supports audio sample-rates up to 48KHz. Batman Returns was the first film to use the Dolby Digital technology when it premiered in theaters in Summer 1992. The LaserDisc version of Clear and Present Danger featured the very first Home Theater Dolby Digital mix in 1995.

I gotta head to bed. The encoding is taking kind of long. Thanks for your help. I will report my findings tomorrow.

I am doing all the transcoding as slowly and thoroughly as possible, since I am converting an HD video and image quality is naturally a priority.

maf made this thread ~year ago. maybe there's an answer of some sort in that thread.

Vizzys · « **Reply #14 on:** October 30, 2007, 05:17:11 AM »

yeah i found the thread by searching the word matroska

which links to a thread where the original thread is mentioned

and contrary to what i said then, it is now possible to convert .mkv to dvd

It looks like that first link works really well. As far as I could tell, there's no hit when it comes to video quality. I just have to dub when I get home.

whose distinguished mentally-challenged idea was it to introduce yet ANOTHER encoding format to the gazillion currently available.

*stumped*

TVC15 · « **Reply #17 on:** October 30, 2007, 08:18:06 PM »

Update: Things appear to be going well. Doing the dubbing now. It's a bit touchier since the size f the video file is making things a smidge unwieldy.

TVC15 · « **Reply #18 on:** October 30, 2007, 10:02:31 PM »

Had to transcode the AC3 to WAV. I couldn't get a good sync with the AC3. With WAV at least I know I could hack it up a bit if I need to correct timing. I don't know shit about using AC3s.

TVC15 · « **Reply #19 on:** October 30, 2007, 10:07:44 PM »

Looks like I nailed it. I'm getting pretty decent at video shit.
