I've just tested this method on a small mkv clip but it should work. UPDATE 2: Ok so i MAY have found a solution for us mac users.
#Imkvextract mp4#
The MP4 file then played on my mac fine like it normally would but when i try it on my xbox 360, i get sound but no picture!Īnybody having similar problems? Or able to help in anyway? It did this really quickly as it was only re-encoding the audio, not the video.
#Imkvextract movie#
Exported the video to MP4 movie ("passthrough" set for video options, "AAC" set for audio). As from my understanding xbox/PS3 can't support AC3 5.1ch audio, however they do play the video part which is h.264. The best way to do this was with quicktime pro 7. Then after more investigation i found people saying that you can convert the file without re-encoding the file (changing the container basically). The trouble is that takes about 25-30hrs to complete on my machine. The only one that has worked so far is by converting the whole file to mp4 (h.264 encoding, "go nuts" settings, then in "advanced" set "fit each video in" 4096mb - cos i believe xbox 360/PS3 can't read files over 4gb) in visualhub. I've done quite a bit of research already and have found various techniques. So as many others i want to l play my hi def mkv files on the big screen downstairs. Downstairs is a xbox 360, networked, connected to a HDTV. I have a home network running with a netgear 108mbps router. I have a iMac G5 2ghz Power PC (1.5gb RAM), with the mkv files on. Let me first explain exactly what i'm doing and working with. I, like a lot of people now, have some hi def. mov that VisualHub spit out (after 10 hours.), and the difference is amazing on the 73''.This seams to be a topic going round quite a bit at the moment.
#Imkvextract 1080p#
I have compared the DVD Transformers with 1080P upscaling to the 720P. I haven't watched it yet but I skipped to an hour and a half into the movie and the video/audio is perfectly in sync, also I can't tell the difference between this and the mkv at all maximized on my 24'' monitor.Īfter work today I'll compare the two on my 73'' 1080P and let you know how it is. I used Visual Hub with AppleTV 5.1 Preset, H.264 encoding, 2 Pass, and Audio passthrough.
#Imkvextract 720p#
I had Transformers 720P (566x1280 or so) H.264 and AC3 5.1 in an MKV that I got online (Septic version). You can change to profile 4.1 very very easily using this h264info.įor me though, I just used Visual Hub last night, and I'm very impressed. H264info will let you change the properties of the H.264 video file, after demuxing using MKVTools or something similar. Here's some tips for people still trying to do it without conversion: I found some good leads for windows, but instead of installing bootcamp (which requires a defrag) and going through all the trouble, I just bought visualhub for 23 bucks. I've been working on this for days, and I couldn't do it on a mac. For guaranteed compatibility I don't see any way around a re-encode with correct AppleTV compatible settings. I realize this does not answer your question on "how to" but rather might shed some light on the details of the problem. Hence the ATV HD rental mp4 w/AC3 DD and HandBrake mp4 w/AC3 DD. Its because of this that some of the built in presets in HandBrake are likely to change from mkv to mp4.Īs well, AC3 in mp4 is supported via the spec allowing for private audio tracks.
Having said that, vlc has issues with bframes in mkv's and probably QuickTime with Perian is the best mac playback, however it too has its issues (they are outlined on the perian website). So, tbh I am not sure that even *if* you found the remuxing holy grail, your problem would be solved. Not only the level of h.264 but for instance the atv chokes on consecutive bframes > 6, short term bitrate spikes in excess of 10MB/sec etc. mkv video's found via bittorrent, etc are *not* encoded with the ATV in mind. However the points about the video still not being AppleTV compatible are extremely valid, even if you found a quick way to do it.
