mkv files on the pc or 360 - converting ect.

Found 8th Feb 2009
Hi,

I have several files just over 1gb in size which are mkv files, they won't play on my laptop using vlc - I get sound and the image but the image breaks up right from the start then locks up and just the sounds continues with the picture frozen a few secs in.

I'm pretty sure the files are OK, I think it's a problem with my laptop - anyone know what the best thing to convert them to is so I can try them on the 360 instead - it just says no video files found when I try to make it play the mkv files at the mo.

thanks,
worto.

had the same problem, type in convert mkv in any search engine and it will tell you which programme you will need to convert to avi, normally cnet download is pretty good, you can then either buy the software or down load the programme as a torrent and load onto your pc.

cheers

The new DIVX 7 player and codec supports MKV files,

Give me a PM if you need a copy

The problem is MKV files are designed for HD if you convert it back to an AVI then it wont be HD. "the most common use of .MKV files are used to store HD video files"

Or you could use this advise from MKV

AVI files can contain HD content. AVI is a container of a video encoded in a certain codec - it is not a format. Subsequently, HD content can be encoded in AVI files. Conversely, MKV files (also container for video content) do not have to contain HD content, although HD video is the most common use for MKV files.

For the OP, MKV files are containers that hold files encoded in a certain codec. The usual codec is H264 and you require H264 codec to play the files. If the MKV file was encoded in a different codec then you will need the correct decoder. If you download Windows Media Classic Home Cinema (see [url]www.freewarefiles.com[/url]) then the file should play from that player as most of the required codecs for MKV files are built into this player.

AVI files cannot broadcast HD content they may contain HD content but they cannot emulate HD otherwise we would not have blu-ray players? a 350mb AVI file is about 1.1gb in a MKV file, show me an AVI file that is comparable to a HD file and i will eat my hat (and i dont wear one!!)

To appreciate the HD quality of a HD file you need the relevant devices to watch them on, if you have an xbox without HDMI then you will never obtain HD (either 720 or 1080) however you can purchase a device that can enable your Xbox to output in HD from xcm.com if you dont have the HDMI version, also if you PC does not have a DVI-D or HDMI output you will not achieve HD

Broadcast HD content? Does Freeview HD or Sky HD broadcast HD content using MKV or AVI files? Both AVI amd MKV are containers not a format, as I mentioned - there is a dichotomy between a container and a format. Within the container, metadata specify the resolution of the video, details of the sound encoding, and so on. As it happens, since the metadata allows a resolution to specified, AVI files (and MKV files) allow for resolutions of higher than standard definition - that is HD.

A PC can achieve HD without DVI (DVI-I or DVI-D) or HDMI. VGA is a classic example allowing for very high resolutions. A PC without HDCP decoding along the chain does NOT allow for playback of HDCP encoded data such as Blu Ray films - there is a difference. Everything in the chain must be HDCP decoded including the graphics card and the monitor. For AVI and MKV files, HDCP is NOT encoded and so these files are playable on a PC, whether HDCP enabled or not.

thanks for the answers guys, I had to put the little un to bed - I'll read through your replies and give something a try tonight.

I use ]gotsent to convert mkv files to mp4's to play on my ps3, you should be able toi play the converted file on a pc ,not sure if they work on a 360 but you could try

A pc cannot transfer HD content without DVI-D (Dual link) or HDMI, VGA cannot transfer HD files at all,HDCP is only enabled as long as you have the device and the cable that enables HDCP,

MKV is a container but it is designed for HD content, it is misleading to think that you can play a MKV file on a PC and the playback will be HD? you may be able to play the file but the quality will be no better than a standard avi file, hence what is the point of downloading a MKV file if your device cant support it and you have to convert it to an avi file!!!!!

With your reasoning you are saying if i had a 5 year old laptop i could download a MKV file and convert it to AVI, watch it and then it would be HD quality? so what is the point of downloading a MKV file?

If your resolution on your monitor is not full hd or 720p then how could you ever obtain HD?

HD is NOT restricted to 720 and 1080 vertical pixels! HD is a term that defines higher than standard definition, although it is difficult to quantify because standard definition is not easy to quantify too (although most in the industry use 480 vertical pixels as a yardstick) . Most monitors are capable of much higher than 720 vertical pixels and as it can be argued that higher than 480 vertical pixels is defined as HD, then these monitors will display HD content. Furthermore, PC monitors are progressively scanned too so a monitor with 1024 vertical pixels could be correctly described as having 1024p resolution and one with 1200 vertical pixels could be described as having 1200p resolution but it may not meet HD Ready 1080p (loosely referred to as Full HD - which is wrong nomenclature). Despite 1200p being higher than 1080p it will not be HD Ready 1080p compliant if HDCP decoding is not built in (see next paragraph on an explanation of HD Ready).

Now "HD Ready" is slightly different. It is a specification for a display to support 720p or 1080i signal WITH HDCP DECODING (notice I mentioned signal rather than display - it is important because the display can still be less than 720 vertical pixels as long as the signal meets the specifications). This has nothing to do with playback of AVI, MKV, WMV or other video files. It is the minimum specification for a TV to play HDCP encoded video such as Blu Ray and (possibly in future, Sky HD). HD Ready 1080P goes further by introducing 1080p resolution into the specifications.

Here are some HD clips in different containers:

highdefforum.com/hig…tml

As I said, HD Ready TV is NOT required to play these videos - a monitor with HD resolution (which covers a percentage converging to 100% of all computer monitors currently in use) will be able to display these clips. I bet your monitor has higher resolution than 720 pixels in which case it is capable of playing HD content but may or may not play HDCP encoded content such as Blu Ray films.

DVI-D is NOT DVI dual link, either (DVI dual link allows for higher resolutions due to extra pins, DVI -D is a digital only DVI interface and DVI-I is a DVI-D with 4 extra pins to carry analogue signals of RGB and a synchronisation signal). It is also not a requirement for transferring HD content! A hard disc can be used to transfer HD content as well as a lot of other forms of data storage. A DVI cable allows for HD content to be sent an an electrical signal whereby the amplitude of the waves specifies 1s or 0s. A VGA uses the RGB format that composes the picture (in fact, same as component cable, which also is capable of carrying HD signals).

RE: "you ay be able to play the file but the quality will be no better than a standard avi file, hence what is the point of downloading a MKV file if your device cant support it and you have to convert it to an avi file!!!!!"
Answer : You havn't read or cognised what I have said!

End of discussion.

Your hat Mr clondike?

Im sorry but i work for a company thats sells DVI-D (dual link) cables and HDMI cables for a living and your statement is totally untrue, you are also quoting text from googled questions??

If you cannot answer from your own knowledge rather than quoting a web search then there is no point, i could give you any advice for any question from the internet but i would rather use my own knowledge, i have been a contributor to wiki regarding the matter,

Contributor to wiki? Could you change wiki's article on DVI to specify that DVI-D is DVI dual link and NOT DVI Digital as I said?

To answer the OP's question, will your laptop play other HD files?

You need a fairly meaty machine to play them, I think Core2 Duo is the minimum, but I may be wrong.

I have never tried playing video on the 360, but you could try just renaming the files to .avi - would be worth a shot

I use a popcornhour to play MKV files and if I remember correctly Western Digital did a similar HD media tank that was posted as an offer on here not to long ago.

Ive been converting hd mkv files to wmv. It takes a long time, but its worth it to be able to play them on the 360.

I use a program called mplayerc to play the mkv on the PC.

files.filefront.com/mpl…tml

But I also have this other program mkv2vob

videohelp.com/too…vob

Which converts the mkv files to mpeg in like 1min or less and you can play the mpeg in the PC or in the PS3. The mpeg do not work in the XBOX360 though :x.

If your PC or laptop is not fast enough you might have problems. Before with a P4 3.2GHZ I was struggiling and having simliar issues with the sync between sound and video, but now with a Quad Core 2.4Ghz works fine. The mpeg works fine in the PS3
