MKV File Format - General Questions and Answers

I've just installed CorePlayer but it doesn't seem to recognize all videos I've downloaded in Vuze (MKV) - unknown file format! That seems strange, since the MKV file format for Vuze videos (Matroska) was actually developed by the CorePlayer people. I have a HTC Touch GSM (Elf) running on Onyx Ultimate 4.2 ROM (awsome, by the way).
So, any thoughts?

From what I have seen - MKV format is usually used for high def video's. I have not heard of any PPC supporting this format yet and many people don't even know yet what codec's they need on their desktops to run this format of video. You must have a large micro SD Card as a typical high def movie in MKV format would take up anywhere from 6 gigs to I have seen as large as 9 gigs. That is too much memory in my opinion to waste on my PPC - On my desktop is a different matter as I have plenty of drives and drive space but my PPC only has 16 gig micro sd and I don't want to fill it up with 2 movies only.
Stick to Divx - Xvid type files - you know .avi's and encode them again using something like pocket Divx encoder or something for viewing on your device. Not only will a typical movie only take up maybe 300 megs but it will still be very good quality for viewing on your PPC

Thanks a lot for the tips. However it is a bit strange tough. As I've mentioned they sell coreplayer mobile specifically to windows mobile operating devices, and MKV is one of the formats it should support. So it shouldn't be an issue at all. As for the movies size, I was not talking about full lengh movies encoded in full hd. I was referring to some documentaries that are encoded in mkv. Those files never surpass 700gb.
Thanks again,
Marcelo.

Having problems with videos

Hi, I put some videos on my phone and it plays so slowly and skippy (sorry dont know how to explain) that it upset me !!
what do I have to do?
this videos are WMV format
what kind of formats play well? or what?
Are you for REAL???????????????????? You must be a brother to Jeb, say it aint so!

Send me your phone via Postal Mail and I will fix the video problem for you.
I understand the problem. I have some files that have similar issues. Each video is coded for a specific bandwidth. If you have an XP machine you can open Windows Movie Maker (its on there!) and load the video into it. From there save the video out (Ctrl-P) and set the video rate to something under 250Kbps. I usually use 218Kbps. The file will likely shrink in size and will play very well on the phone. You can set it larger but you will start to see performance degrade.
Movies encoded in Divx format at 320x240, audio at 95 to 128kbps Stereo with a total bitrate under 500kbps play and look great on Kaiser. Movies are approx. 400-500mb per Movie. I just flew cross country and watched 5 movies across 4 flights and can say that the Kaiser performed flawlessly. Using TCPMP (I have core as well but use TCPMP and the streaming bundles for now) and WoW SRS, the audio thru wired noise cancelling earbuds was really excellent with suprisingly good bass!
Bottom line, I know it could be better with the correct drivers, but if you encode in this fashion this phone kicks ass as an all-in-one device. With 1.2gig taken for iGuidance and North America maps, I still carry 12 full length movies and still have room for pics and progs on my 8gig card.

Video's On The Fuze

How will you get a full movie (Wall-E) to work on the AT&T Fuze? Do you have to convert to a different format or size? Please help.
For best performance, it's best that you convert it. The more you start doing it and mess with the settings, the better you'll become and find which settings yield the best results.
I originally tried Quicktime Pro for this, but the people at Apple have decided that the iPhone screen is the biggest resolution they want to support on export, and I don't want the player scaling up, so I had to look elsewhere.
I'm playing with a program called Allok MPEG4 converter (http://www.alloksoft.com/mp4_converter.htm), which seems to do a nice job if a bit slowly. Of course, to do a nice job requires LOTS of processing power. I have been using the defaults except for making the output H264 and 640x480. Once the files are converted, I just copy them to the Fuze's SD card and play them from there.
I use a program called VideoReDo (www.videoredo.com) to suck in the DVD files and make a single large MPG file from them (the free DVDShrink will also work for this, if you can still find it somewhere), then load that single file into Allok and let it run. A decent DVD will take pretty much overnight to process. The results have been very good so far.
Start with a small (5 minutes or so) piece to practice with and try various settings, then when you're happy, let the full movie conversion run overnight.
Also, be aware that most commercial DVD's will have DRM and you will have to deal with that before you can do anything with the files.

If you are converting from an .avi file then you can try PocketDivXEncoder (freeware). It has presets for Diamond which you should start with. You should decide whether you want VGA or QVGA. VGA should look a little sharper but will be ~30% increase in file size and on a 2.8" screen the difference may not be much. Test for your self
I would modify some of the settings though. Leave video as is. Change the audio (small arrow on the left) to 32Khz 80 kbps stereo. Go to advanced and tick 2-Pass and Xvid.
What is your source file for the movie? If its on DVD then you definately want to convert it. Once all of my media is ripped or converted to the container / format I want I leave it at computer base resolution and just play it on the phone. Core player has done pretty well at handleing what I put at it so far.
Now that PocketDivx Encoder is a good program and does a pretty good job and shrinking files down.
Any recommendations on codecs, resolution and bitrate? I would especially be interested if anyone knew which settings preserved battery life the best while watching video.
Menneisyys has a good thread on video playback.
I use Core Player and I really don't covert any of the TV shows that I watch.
Windows Movie Maker is a great tool too. Its free (if you have XP SP2 installed) and it uses WMV format that Windows Media Player Mobile will play without any addons.
If you watch alot of movies on your Touch Pro I would suggest investing in Core Player, it plays most of the commonly used codex and its pretty quick too.
Bit rates and resolutions: I have found that if its a TV show that is about 40 to an hour, I dont have to do anything with it. For example an episode of House is about 42 minutes long, its 624x352 and running at 23.97 frames. With Core Player the episode looks flawless, eventhough the statistics on Core Player say its dropping frames, I can't tell.
I would think that a full length movie would perform a little worse, or a TV show with alot of action.
Also fatheadpi has this thread posted about encoding video for the Raphael phones.
Thanks for all the reply's. I'll try them out.
Watch Movies on Fuze Problems
So I got an HTC FUZE not too long ago and have been trying desperately to get it to play movies.
Windows Mobile Player does not want to play the wmv files I give it...
and no matter what file I use with CorePlayer the audio is terrible
mpegs, mp4, avi, h.264...
All of these videos will play fine on my computer but as soon as I get it to my phone, the audio goes to crap.
To make it all more difficult, I only have a Mac to sync this device with, so Windows based programs are useless to me...
Any suggestions would be greatly appreciated.
Thanks all,
'Jammin
I too have been trying and so far no Success
Operating my Fuze in cooperation with a Mac Laptop is difficult enough. The programs most suggest to convert videos exist mainly for PC.
I have used many methods of conversion and found no luck with producing watchable quality on my FUZE
CorePlayer gives me bad audio playback when the video played perfectly on my computer
and Windows Media Player will not play my bigger wmv files for some reason.
Let me know if you found a combo of programs and settings that really works

I use this and it works great. Converting the video is a pain in the butt.
+1 Take time to convert but yield a much better result in viewing your video in either Album or WMP
Thanks for the info, but isn't that program for PC's?
I have many different methods of converting videos
from freeware that helps me with wmv's (as I am on a Mac and that is somewhat hard to do)
To Final Cut Pro's Compressor and even Adobe's version
Windows Media Player on my Fuze seems not to like any files over 100mb
and even though the video will look awesome on my computer after conversion, the players I use on my phone completely destroy the audio...
I've searched up and down threads like these and am at a complete loss...
qwik question
which is better to convert movies to my fuze spb video or avs video?
sorry people
um what size micro sd card on average would I need to store the videos?
get at minimum a 4GB microSDHC... under $8 if you're lucky
or a 8GB for $16... no reason to jump for that now that memory isn't that expensive
Use coreplayer bro
I bought it, and its amazing $29.95... Don't convert anything that I get. It only has trouble with on6 flv files, and devs say it'll never support codec. Shame, because flash 9 and 10 protected movies are almost all encoded with this...
A small ffmpeg utility can run one through flv to avi, keeping aspect and original source resoultion, and process a 1.5 hour flv file in about 3 minutes and give you a great quality avi output for your phone
With TCPMP I get lag when watching full movies, but Coreplayer is fine
Set video to the qtv display, high quality.
If you've got bad audio, perhaps you need to lower the pre-am if muffled, or increase if quiet
Also, you may have equaliser enabled, and not know it.
Check the options section go through pages
There definatley should not be a problem playing media with this program
Only problem now is.... I bought this... ya sweet - but now can't afford to get my raph unlocked until next month
So still without a mobile

News Flash
Disney released Wall-E on DVD and Blue Ray discs. I have yet to see a cell phone with a built in DVD or Blue Ray player.
The motion picture experts group (standards body)...MPEG for short, many years ago, decided to evolve the distribution techology (for consumers), from MPEG-2 to MPEG-4. MPEG-4 is a broad spec and covers everything from small hand held devices to HD quality video (H.264, VC-1 etc).
Your Touch Pro has built in hardware acceleration to handle MP4 up to a reasonable limit. Your best built in video players, as delivered by the OEM, are HTC Album and Windows Media Player. Both apps support hardware accleration for MP4 video.
I continue to read about (and have purchased) Coreplayer. In the mobile space, Coreplayer is a modest improvement over the free open source TCPMP player. CorePlayer, caused a brief stir when they half-hacked into the (modest) built in hardware acceleration on the HTC Kaiser.
On a Touch Pro, Coreplayer does support non industry standard video formats, but only in software mode (slowly rendered down sized formats). Coreplayer fails dismally, when compared to Album or WMP for MP4 playback.
So...yes, convert your content to a fully supported format. Or...leech your content in supported formats. Search this forrum and you'll find guidance, and free conversion tools.

3D films larger than 4GB?

I want to put some 3D films on my phone but they are all over 4Gb so I either need a way to make them smaller or split them or alternately somewhere else to download 3D films from that are smaller. I use a mac as well.
Thanks.

That's a restriction of the FAT32 filesystem. On my Windows machine I use Handbrake to reencode large movie files, it's available for MacOS too if I'm not mistaken.
You can use this guide which someone made for converting files to play on the Evo3D. You don't have to reencode to MP4 as the O3D can play mkv natively and you can play around with the quality settings if you like. I've noticed no difference between 720p clips and reencoded 800x480 clips. With the settings in this tutorial a movie of about an hour and 45 minutes will be no larger than 2GB and the quality is pretty good.

[Q] DVD / Bluray ripping?

I have some mkv files on my desktop of the kids blu rays, but I'm looking for something to put it onto the tablet for a plane ride we have to take without having to lug the portable dvd player around. I was thinking about putting some of the files onto my old 7" SGT for my daughter and wondered what might be a decent way to do so. I read about handbrake a little, but wasn't successful in the past when I was trying it out (decryption problems). That was a while back, but wondered if anyone is using anything more current that might help me out.
In addition... is MKV workable on the tf700? It's going to gobble up a ton of SD space but might be fun...
first, try this:
drag the videos to your device, and then download DicePlayer or MX Player (diceplayer if my fav when it comes to mkv). Try playing the videos with either app.
if you experience issues, you can convert using handbrake (i havent used this app in a while), or you can go with DVDCatalayst, my preferred method. It has tons of preset for all devices and is easy to use. I convert 4gb blu ray movies all the time. Shrinks them down to about 1 to 2gb, depending on which preset you use. You have the option to go smaller or bigger.
Another good player is BSPlayer (incase you want to try). Like timrock says, most files play just fine. I'm also using Wondershare player to play DVD's (like VIDEO_TS files), but Dice/BS can both play vob files too.
Are you ripping out to VIDEO_TS folders or can you make a single MKV file to make it easier to transport? I only used MKV's for blu rays but I assume it would compact the DVD's down a little from their full size a little?
I just put a 20gb bluray rip on my 64gb microsd, movie plays great with bsplayer. Keep in mind only h.264 videos will work. Blurays with vc1 video will fail.
One of the main advantages of a droid tablet is you don't have to convert the vast majority of titles out there. I spent so much time ripping stuff to my ipods and psp before. With tegra 3 and mxplayer, I can play basically everything.
Personally, when I have MKVs, I use XMedia Recode to recode them to MP4 -- it lets me copy the video without re-encoding, which takes only about 5 minutes to re-encode a 2 hr 1080p video. I do this for both my phone, tablet, and PS3 media server.

This method will not work with mkvs that come from vc1 based blurays. Mp4 can't contain vc1 video and so far nothing can play vc1 on infinity with HW accel.

I must be doing something wrong - it takes at least a 1/2 hour to recode a mkv rip of a full length movie.

You sure it's actually re-encoding it and not just transcoding it? E.g. is the size about the same as before?
MKV and MP4 are just container formats, you're just wrapping the actual video and audio streams into different container formats, really. Transcoding is pretty much just copying the streams which is fast (usually limited by disk speed), while re-encoding is a heavy CPU/GPU task. Even with Quick Sync it'd take quite a bit longer for a 90+ min movie.

Correct all that tool is doing is repackaging the video and probably transcoding the audio into stereo, into MP4. If you use BS player there is no real reason to do this.
Fifth Element mkv is 27gb so I have to transcode it... guess I am doing it right after all...

I tried this method and was pretty smooth, but I find the brightness of the converted movie 'hunts' up and down a bit during playback. Not quite sure how the various options work, but is there something to check?
Handbrake Preset for the TF700
I have been doing this with Handbrake for a while now - But not for the Infinity! I want to take advantage of this new fangled Full HD Screen.
QUESTION:
Does anyone have a 1080p Preset that they have created and verified as working for the Infinity? I did a few google searches but they either use a different piece of SW or are focused on 720P!

Just FYI, torrenting movies is illegal, _even if you own the movie_. Why? B/c you are still giving away the movie to others (peers) while you are downloading it. Just sayin'

Video Converter Software

Hello.
Well, I have been trying to work my way round the Video Softwares for the Note.
I already have a good software - Badaboom which is nVidia Certfiied as it uses the GPU for both Encode & Decode.
The format that I use with it for the Motorola Xoom, same display resolution as the Galaxy Note.
However, I have noticed that the output is not as what it should be.
It seems a bit off.
The movie which I have encoded is a Full HD 1080p. - Original Size is 7.8 Gigs or so and the Rip comes out to 3.02 Gigs.
There is a little noticeable Lip Sync, but the picture is little different.
Have you tried MoboPlayer? It has a soft decode feature which can play back pretty much any format (no need to convert any files at all ).
DVD Catalyst?
Badaboom sucks. It's fast, but quality...meh. GPU encoding has a long way to go.
If you have a decent CPU and are not too technically minded try Handbrake, it works wonders.
I owned a Xoom myself. The screen is nowhere near as rich as the Note although they have similar pixel resolution.
I tried handbrake and it looks nice but doesn't take dvd rips, ie .vob files? But it will scan a dvd to rib? I alway rip my dvds with dvdripper on mac then convert them when i fell like it. Even though it seems more realistic to just rip the dvd to the desired format in the beginning.
Edit: so i tried some things. for awhile i was doing full dvd rips, then i started just doing main feature extraction(to save space) and in handbrake when trying to load the main feature rip it says no source found. When i select a full dvd rip it loads. Im assuming handbrake is looking for the audio ts folder among other things to think its a valid source ... Bummer because i save 1-2gb by not doing a full dvd rip...
MX Player will play .vob and almost all other formats.

Try VLC Player, Its only beta at the moment and is almost identical to mx player, I use it on my pc and you can adjust audio sync and stuff, I'm sure these features will be available soon on the android version.

I have to say I am not sure what you are trying to do here, have you ripped a DVD to VOBS and then try to encode it again?, why don't you just rip the DVD straight to a compatible file with a compatible codec that your PC, Phone and Tablet can handle.
Most devices can handle a 1080p Hn64 high profile rip as long as you have summed audio channels to stereo, this way you can have very large bitrates and upscale your DVD's to play on your PC as well. Playing them on your Tablet and phone will be smooth if you use the sammy video player as hardware acceleration will come in to play.
