    On 800x480 Evo, if the source is 16x9, it indeed goes full-screen.

    Simple hacks have been out for some time to partition the SD card and make at least a part of it an ext filesystem (hacks are really just instructions). Don't recall if that changes max file size. Most of those were to offload a part of the OS to the SD card - I tried that for a short while last year when tinkering, don't recall what I was I up to at the time, but I went back to stock. (I think I went down that path as part of a kernel tryout.) You could use it as a workaround to get your apps on the SD card, also (that was pre-Froyo).

    I've seen that mentioned on Sammies, haven't been able to converse with anyone to get a clear explanation on what's up with their phones. I've been under the impression that you always needed a FAT32 partition as primary with Android.

    Have not heard of anyone using NTFS. I don't think anyone's of the illusion that FAT32 is ideal, just universal.

    Well the 4GB limit comes form the FAT32 format. ext2 and ext3 max file size depends on the blocksize chosen at format time but min is 16GB.
    -
    I don't consider it a hack to format the sd card with ext2 or ext3 as long as andriod support it; but I'm a linux user so it is fairly easy for me to format the card anything but fat32 (where I have to use a windows box).
    -
    Might require fat32 for primary; that strictly depends on what file systems the boot loader understands.
    -
    Sadly a simple web search didn't return much here; it did not that the andriod kernel will support all native linux file systems so extx shoudl be fine (not sure if the andriod kernel supports ext4 yet which is newer than
    the others) but i could not find anything on the boot loader. Oh well; the boot process isn't going to touch the sd anyways.

    I've seen chatter about the SD card and the bootloader. I went and googled it up again, but what I saw was so much chatter that I didn't bother to post links.

    Agreed on non-hack hack - but for the general Windows public, anything non-normal is hackish so many giving instructions list them that way.

    So If I want to put an hour HD recorded Tivo show on my SD card it will fi tbut it has to be under 4gigs is that it? Or do I format my sdcard? I know there is fat32 and NTFS and I know on my flashdrive an hour HD show wouldn't fit.

    It will fit if the file is smaller than 4GB. It all depends on the bit rate not HD vs SD. If the stream is less than 8.5 mb/s then an hour show shoudl fit fine; else you will need to reformat your sdhc card with a different file system or you could split your show up into two pieces (part 1 and part 2 :) )

    Yes, a friend has a 32GB SDHC and has tried placing a ~25GB file on it, which parses and seeks perfectly under ext3. I do not know any of the specifics of the partition details.

    To format an SD card to FAT32 in Linux, I've used mkdosfs -c -F 32 -n MyCard -s 64 -S 512 -v /dev/sdc1
    Graphically, KDE Partition Manager seems perfect for the job, too. You can of course fiddle around with the block/cluster size (size 64 clusters facilitate higher performance with larger files but more wasted space when storing multiple tiny files), and obviously replace sdc1 with your hardware's SD read point.

    A border is used as needed to maintain correct aspect ratio. When the aspect ratio of the video doesn't match that of the screen, the Sense player has options to adjust the scaling -- clicking the 'screen' button in the player controls its behavior. Playing 16:9 videos on a 5:3 QVGA screen can result in one of the following AR-maintaining behaviors, according to what setting is selected:

    • Resizing the video so as to ensure the aspect-limiting dimension of video fills the screen perfectly in that dimension; the other is simply 'out of bounds' and thus entirely cropped off. This is destructive in that you are losing (often significant) parts of the image entirely due to cropping. However, the portion of the remaining video area is allowed to fill the whole screen, resulting in greater size/detail in the remaining area.
    • Resizing the video so as to ensure the non-limiting dimension fills the screen perfectly; the other is sized accordingly in tandem with the creation of the 'letterboxing' (black bars) effect. This is much less destructive to the visible area of the video, but more so to the detail within it (it no longer fills the whole screen).
    • Native size (DHD/some builds only): Video is not resized if it is already large enough to fit within the display. Note that the above scaling methods will also leave the dimensions untouched when the video already perfectly occupies the screen area.

    Scaling (like decoding, provided you are using an appropriate player like the Sense player) is done in hardware. I believe the resampling method is bicubic interpolation on the Adreno 20X series, given the GPU's realtime bicubic scaling ability, but I haven't run any tests -- it could very well be a primitive bilinear function depending on the parameters of the decoder/GPU/player.

    It has been my experience that most people with whom I have regular contact prefer the area/aspect maintaining scaling (method 2) rather than overcropping (method 1), especially when loading a video with subtitles in which portions thereof would be cut off when the sides are cropped during the 16:9 -> 5:3 conversion. In the case of non-destructive scaling (with attendant letterboxing), 800x450 is the screen's maximum physical output after hardware resizing, for a total of 360K pixels. Things get even worse when playing 2.39:1 content, but let's ignore this for now. AMOLED displays like that of the Galaxy S, by some estimates, have an effective PenTile resolution of 653x392, causing 16:9 content to display as 653x367 (240K), which is especially jarring when viewing sharp edges (anime, text in seminars/slideshows, etc).

    The 3VO, in contrast, has a natural aspect ratio of 16:9, which is ingenious on a portable multimedia device. 16:9 content would be scaled perfectly to the screen resolution of 960x540, for an output of 518.4K pixels. That's a 44% increase in resolution over QVGA on all 16:9 content that is isn't destructively cropped (or a whopping 116% more than a PenTile AMOLED display of the same). The usable screen area is also maximized in this case, obviously, so no letterboxing is present and the video can (again, non-destructively) occupy more physical screen area as well.

    Samsung used RFS, its own heavily modified filesystem compatible with FAT16/32 (and a somewhat lacking implementation thereof, I daresay). FAT32 in and of itself shouldn't be significantly slower than other filesystems on solid state media, since its largest issue (fragmentation) is largely irrelevant read-side with random access capability on NAND flash, be it internal or within removable flash media. YAFFS, NTFS, journaling filesystems, btrfs and the like support more features, flash-specific tools, less propensity for fragmentation, enhanced delayed allocation, and higher read/write buffers by default, often resulting in greater performance for burst read/writes, higher data resilience, and FS compression (NFTS/btrfs) for additional space savings.

    Man, you guys are all idiots! Why not make it easy on yourselves? Just put your dvd/blu ray on your Tv, prop up the 3vo so that its recording the screen and WaLa! Movie is now on your phone, and you didnt have to waste time worrying about aspect ratios and what HD level to convert too...Gahhh! Do i have to think of everything around here?!?

    So Handbrake works just fine with 3D side by side mkv videos. I downloaded a blu ray 3d movie and converted it down to qHD resolution, and playback wad just fine. I cam see myself purchasing 3D BLU rays to port to my phone.

    Will we be able to watch our regular movies there 3d format, or will we have to get movies loaded for 3d only. I have tons of movies on my 32 gb card, but of course none are 3d.

    They will have to be stereoscopic 3D, not anaglyph. Anaglyph is the red/blue 3D that requires glasses.

    Give it a year, and I'm sure there will be one solid format of 3D that everyone will use :p

    No, you're not alone, you don't have to think of everything like that.

    Fortunately, the MPAA is here to help - in fact - in 2009, that is exactly what they insisted teachers do for classroom videos in order to escape their copyright wrath.

    I kid you not.

    MPAA: teachers should videotape monitors, not rip DVDs

    ~~~~~~~

    Mod voice:

    I just wanted to take a moment to thank everyone for walking the fine line we are required to walk, thanks to the DMCA, and not posting disc ripping details, just sticking to the handbrake kinda stuff.

    Nicely done, thank you!

    I use DVDCatalyst, which has profiles for most phones. It will rip a DVD to optimal format. Lots of customization options as well. It's free but I us it so often I donated the $10.

    It's not free. There is a limited "free trial version" that converts 25% of any file. Also, no guarantees it will take full advantage of the 3VO's decoding potential -- when the 3VO comes out (rather, when I get one), I'll look into it myself and post the max AVC spec and feature subset it actually supports, at which time you can use any (free) frontend to get the same or better result.

    just a clarification here: anaglyph is just a different way to present stereoscopic images.

    .JPS seems to be catching on. It's basically a .JPG file with left and right images next to each other. Very easy to make your own. Evo 3D reads .JPS apparently as well as another format, .MPO.

    There is some sort of 2GB file limit. I can't wirelessly transfer a file over 2GB through any of the programs I use (ES File Explorer and Websharing are the two I use most). But I can transfer a file between 2GB and 4GB by wire, and they play without a hitch. So there is a file size limiter that affects my ability to transfer, but does not affect playback (or USB file copy).

    Unless someone can verify that you can playback 720p video using a software player like Rockplayer or MoboPlayer on the Evo3D, you will have to re-encode to mp4 for HW acceleration.


    I totally and completely agree with you. I own a 61" 1080p TV. I have looked at 8GB 1080p video and a 2GB 720p encode of the same movie and I can't really see much if any difference between the two. If the 8GB file was blowing away the 2GB file in video quality or at the very least be discernibly better, I might think the size difference was worth the difference in video quality. But I just don't see it, and it's certainly not worth the 6GB difference in file size. If you're watching these videos on a laptop or you have a larger TV or you are sitting closer you may see real differences in picture. But I don't, so it's 2GB 720p for me.

    I got my blu-ray rip of Avatar, but when I try to play it on my Evo, it plays in 2D, is there something special you have to do to get it working?

    As far as I know the EVO3D can only play side-by-side 3D movies (someone please correct me if this is wrong). What this means is if you view the video on a regular movie player, you will see two video images playing side-by-side. When you see this all you have to do is hit the menu button on your phone and then select "Play in 3D" so it will start playing in 3D.

    I highly doubt that the Evo will play back your Avatar rip in 3D. It's not utilizing the same technology. Also, random comment... It seems a lot of people on this forum think that recording a 3D movie/picture on your Evo and then uploading to your computer, that the image will be 3D on your computer. That's impossible as well.

    Your information may be in error or incomplete.

    (lion2) -- The CTIA vid had the rep state in no uncertain terms that the 3D on this phone supported both left/right (aka SBS (side by side)) as well as top/bottom formats.

    And no one here naively believes that you can play 3D on non-3D displays -- and btw, the new glasses-free 3D Toshiba laptop (with the ability to have separate 3D and 2D zones on the display simultaneously) is already out in Asia and may be already be arriving here as I type this (or is here, or coming soon).

    the mp4 container is very flexible, and the Evo 3D knows how to read mp4 with 3D data, as its own video recordings are saved in mp4. So if a 3D movie is not playing properly, it's gotta be a screw-up in the ripping/encoding process. I'm not an expert in that area and can't provide a solution, but I know firsthand it can be done. That's all I can say about that.



    You can most definitely view Evo 3D content on a computer and/or TV and see 3D, but there's a manual process involved (just like the encoding process to get video on the phone). I do have the knowhow here.

    If you have a 3DTV and a player that can read a 3D field-sequential mp4 file, it will work just fine.

    If you don't have a 3DTV, you have less desirable options:

    1) convert your stereo pair to anaglyph. This is an easy post-process step you can do with photoshop. Google it. Requires red/cyan glasses.

    2) display your stereo pair, making sure that the subject distance in each frame is no farther apart than the width of your eyes, about 2.5." Since pixel densities vary, you tend to have to shrink down the stereo pair quite a bit. Then to view the 3D without glasses, you have to focus your eyes behind the screen. This is known as parallel viewing.

    3) this is probably the best option in terms of image quality but also the hardest for people to do: cross-eye viewing. Reverse the left and right images. Keep them big. Cross your eyes (focus on a point in space in front of the screen). When the images line up, you can see the 3D.

    Option 1 is the most comfortable, but the red/blue tint really affects the color reproduction. After a few minutes though, your brain does tune out the two colors somewhat and you perceive what colors should be there.

    Option 2 and 3 are how steroscopic images have been historically presented, often as 3 pics: left, right, left. If you can do cross-eye, look at the RL pair. If you can do parallel, use the LR pair.

    Want to try your luck? See this thread. OP presents a cross-eye stereo pair. Further down, there's a parallel-viewing pair. Although those weren't generated by the Evo3D, there's no reason why you couldn't apply these viewing techniques to Evo3D-generated content.

    Also, when taking 3D photos, I recommend changing the image format (in the camera app settings) from .MPO to .JPS. The .JPS format is just .JPG renamed. If you rename a .JPS image to .JPG and view it with your viewer of choice, you'll see that it's just a stereo pair, Left|Right. Reverse them, and you have a cross-eye stereogram.

    Has anyone as of yet, SUCCESSFULLY converted a 3D blueray disc to file that plays 3d on the EVO ?

    I read a few posts about handbrake, but none seems to have 100% confirmation they actually worked.

    Anyone?

    Well it wasn't Avatar, but definitely just watched one of my ripped 3D Blurays on my phone :) The technology is all in the display device. The 3D movie formats are decently standardized, and all 3D Blurays use the same standard.

    Yes. I used DVDFab, but I've heard handbrake will also do the trick. I have Tangled 3D (hey it's a good movie, don't give me crap) on my phone currently. I just convert it to a side-by-side .mp4 file and when I play it in the phone (as mentioned above), it looks side by side at first. You just hit the menu button and tap "Play in 3D." Works like a charm! It looks very nice too :) Good luck! (Also, don't do anything illegal! :p)

    @Fattank: So have you figured out the optimal settings yet? I'm anxious to get the best quality movies in the lowest space possible on my phone :)
