    I love my galaxy nexus, and have some movies (bluray/1080p .mvk files) that I would like to send over to my phone for mobile viewing - so while converting the movie to mp4 format, I would like to set the proper and ideal (highest for quality/no sound lag/no video lag) resolution.

    Wow, how big are those bluray files?! I've only done dvd's so far as they look great on such a small screen.

    I've been using MX video player for watching mkv videos on my nexus. It works great with avc encoded mkvs provided you can get it to run in hardware decoding mode. For some reason if the audio is encoded as aac it won't let you decode the video in hardware mode even if you set it to use software audio decoding. DTS encoded audio in an avc encoded mkv works fine however. I've played 720p 2gb animated movies and 1080p 6gb live action, both on the phone's screen and over MHL to an HDTV. All ran smooth as long as it was decoding in hardware mode.

    Anything over 720p for viewing on your phone would be overkill, since the screen is 720p. Anything over 2.0 audio would be overkill since the phone doesn't have surround sound. I also would argue that a higher bit rates probably won't be beneficial due to the size of the screen.

    All of that goes out the window if you plan on plugging it into a larger HD screen.

    That said, I have a blu-ray that I did a quick encode of as a test the other day. I encoded to DVD5 size at 720p leaving surround sound.

    My output looks like this according to media info:
    Code:
    Duration                         : 1h 46mn
    Bit rate mode                    : Variable
    Bit rate                         : 4 439 Kbps
    Maximum bit rate                 : 20.0 Mbps
    Width                            : 1 280 pixels
    Height                           : 720 pixels
    Display aspect ratio             : 16:9
    Frame rate                       : 23.976 fps
    Color space                      : YUV
    Chroma subsampling               : 4:2:0
    Bit depth                        : 8 bits
    Scan type                        : Progressive
    Bits/(Pixel*Frame)               : 0.201
    Stream size                      : 3.30 GiB (87%)
    
    Audio
    Format                           : AC-3
    Duration                         : 1h 46mn
    Bit rate mode                    : Constant
    Bit rate                         : 448 Kbps
    Channel(s)                       : 6 channels
    Channel positions                : Front: L C R, Side: L R, LFE
    Sampling rate                    : 48.0 KHz
    Bit depth                        : 16 bits
    Compression mode                 : Lossy
    Stream size                      : 341 MiB (9%)
    It played fine in my test, I didn't watch the entire movie though. I played a minute or so in the beginning, skipped to the middle to a scene that had a higher bit rate and that played fine as well.

    YMMV though.

    great info given and everything --^ said makes a lit if sense. I do not ever plan to stream or connect my phone to a larger TV to view so a resolution that would suffice for just watching on my phone is all I need.

    But I also do not want to loose quality from the movie either. So if I have a 720p MKV live action movie, what should I convert it down to? I was thinking 800x600 but won't that change the aspect ratio?

    I am not the most knowledgeable when it comes to video technology and that stuff so I might sound like an idiot lol

    And finally when I do the conversion, what's the best codex to use? I have Xvid, Divx, h.264, and a bunch of others that I downloaded for adobe after effects (basically saying I have them all - audio ones too).

    So to summarize:
    - best resolution to downgrade to from 1080x720 (720p movie) to use strictly on my galaxy nexus
    - same as above only for 1080p movies
    - which codex to use for audio and video during the process?

    Check out dvd catalyst. It has profiles for the nexus (and many other devices) that will give you a great quality video at an optimum file size. The guy that makes it frequents the forums too and is always very helpful. Well worth the few bucks, especially if you want to take the guess work out of finding a good conversion setup.

    This is probably the best bet. I am not familiar with that program myself, but a program that knows the limits of the hardware (and software) would probably be the easiest method to do all this.

    What program do you use to rip Blu-ray? DvdCatalyst is great for DVDs

    Best and easiest program to use for DVD's and MKV files (or any file for that matter), is DVD Catalyst...hands down. The developer of that program...Mitch, is a good friend of mine. We talk daily about how to push the limits of the movie quality on the Nexus. I have hundreds of movies converted for the OG Droid, HTC Thunderbolt, iPhone 4 and now converting my whole library for the Galaxy Nexus. All my movies are 720p HD MKV's that are converted. You can do 1080p...but that would be overkill.

    You could always use handbrake as a great free alternative. I've always used it for conversions and haven't had much issues. You definitely don't want to go over 1280x720 for resolution. On a phone screen, you could probably go lower because even though the native resolution is 720p, you don't usually hold the phone close enough to your face over the entire duration of a movie where you will actually need that extra fidelity provided by 720p.
