1080p Video Quality

Back when we had the MDP, I took a number of 1080p video samples just to get a feel for what MSM8x60’s ISP and encoder performance were like. Things have improved considerably since then, and compared to the MDP the Sensation shoots much better videos. I had Ganesh, our resident media guru and HTPC reviewer, take a look at everything the Sensation produced and do some analysis, and his initial impressions really mirrored mine. Image and video quality both are better than they were on the MDP, and dynamic range is also improved.

The Sensation lets you shoot in 1080p, 720p, and native qHD resolution, in addition to a number of lower resolution options. Video is encoded at H.264 baseline with 1 reference frame, just like we saw Tegra 2 do on the Optimus 2X. At 1080p you get around 10 Mbps bitrate, and at 720p you get 5 Mbps. Just like the Optimus 2X, “1080p” really works out to 1920x1088. Video is shot at 30fps, though in practice we’ve noticed the Sensation dipping below 10 fps a few times, and to be honest we’d rather see steady 720p30 than 1080p10-30. 

We've done the usual thing and uploaded everything in a 245MB zip to the AT servers, and also to YouTube as shown. 

Bench Video:

Sample:

The Sensation is one of a small percentage of smartphones I’ve seen that also record stereo audio, which is encoded in 128 Kbps AAC. I’ve taken some video with stereo turned on and off, as there is a toggle in the camcorder menus, though I don’t see why anyone wouldn’t record with stereo enabled all the time. 

Stereo:

Mono:

With some digging, I determined that the Sensation is using Samsung’s 8 MP S5K3H1GX 1/3.2” 3264x2488 CMOS sensor with 1.4 µm square pixels on the rear camera. It’s the same 8 MP sensor as used in the Desire HD/Inspire 4G. This supports FullHD by cropping, and optionally HD by binning. Fire up the camcorder and you’ll see that HTC has opted for the former, and crops the sensor down to 1920x1088 for recording videos. As a result, magnification appears to increase due to the crop factor, something that’s old hat for iPhone 4 users. 

Front Facing Bench Video:

The front facing sensor is a Micron/Aptina MT9V113 1/11” VGA CMOS sensor with 2.2 µm square pixels. Video on the front facing camera is shot at 1.6 Mbps VGA in H.264 baseline with 2 channel AAC audio as well. It isn’t anything to phone home about, but no doubt will suffice for video chats and such. 

Still Images

The actual camera application on the Sensation is HTC’s standard fare, and as such I don’t think it bears much going over. The menus are relatively straightforward to navigate, and the icons rotate from landscape to portrait shooting so you know images will have the right EXIF data embedded. I’m a bit disappointed that the menus are still somewhat laggy - opening and closing the settings drawers sometimes just seems sluggish.

The actual preview image is of good framerate however, and the preview resolution seems to be 1:1 with the screen, no cheating here. HTC also still sets the shooting mode to widescreen by default, so to get the full potential out of the sensor you need to go into the menu and uncheck widescreen and shoot in 4:3 aspect ratio. 

As a reminder, locations 1, 2, and 5 are unavailable anymore, but 3, 4, 6, and 7 still are being actively used.

Image quality on the Sensation is pretty good with lots of light. In fluorescent light things can get a bit off, as evidenced by colors in location 7. I’ve said before that HTC’s current crop of cameras far exceeds the previous ones, and I’m still thinking that after having taken lots with the Sensation. It’s clear to me that HTC has been paying attention, as there no longer is a piece of plastic between the camera and outside world. Instead, the last surface of the camera really is that surface, and it’s inset slightly so as to not be a contact point for scratching. The camera module sticks through the rear case slightly, and there’s a small squishy seal to keep dirt and grime from getting inside.

    and I was looking forward to getting the Sensation, especially for its big, high-rez screen.

    I'm thinking of going the Galaxy S 2 route instead:
    - GS2 is much lighter (115 vs 150 grams). Less sagging pants and shirt pockets sound really nice (I currently have a 155g HD2)
    - screen seems better: fewer pixels, but much better contrast and angles
    - Samsung actively supports CM7, I'm not even sure if the Sensation is unlocked (HTC says they're no longer locking, I don't know if originally locked devices get an unlock)
    - everything else seems broadly the same. camera maybe a bit better on the GS2

    I personally think the HTC Sensation looks much nicer than the Galaxy S II, and it also provides all 4 Android buttons, which is more useful.
    Also, Sense 3 is a genuinely nice addition, so I REALLY don't understand the lust for AOSP based ROMs.
    I know which phone I'll be recommending if people ask me...

    I actually registered just to post this, and here it goes:
    Sense (and the other skins) just need to DIE: they're bloated, ugly and inefficient (not to mention introduce bugs that stock Android does not have); worse than that, they are way of creating vendor lock-in and force users to upgrade hardware by withholding Android updates (a very clever trick to neuter one of the greatest advantages of Android, its open source nature).
    Why can't OEMs just stick to do their job? People complain about the crapware OEMs install on PCs (which at least you can uninstall or just format) and somehow this is OK? Also, commodization is exactly what makes the PC ecosystem great: customers can shop around for the best price for their performance needs without having to worry about their devices being left without a software upgrade path or features unavailable. And with phone makers locking their bootloaders the last way of getting out of their death grip, custom ROMs, are being taken away from us.
    Finally, I'd much rather rely on software written by a good software company (Apple, MS, Google) with 100s of engineers dedicated to the project than the much smaller team an OEM can afford to put on the job.

    Well, I have a Desire HD, rooted, s-off, I can put whatever the hell I want on it...

    Oh, and I choose to use a sense based ROM with Sense 3. I've had a phone with pure CyanogenMod, it's all well and good, the point is, as long as the phone isn't horribly locked, and xda-dev get their dirty mitts on it, you can have whatever yo uwant!
  • piroroadkill - Friday, July 1, 2011 - link

    Oh, that said, I don't use the launcher. I use Launcher Pro.
  • Chloiber - Friday, July 1, 2011 - link

    Exactly the same here, except I'm using a Desire (non-HD). I really like Sense. I rooted the phone about one year ago and was using Stock Android ROMs a lot. I really liked it. Now I returned to a Sense 2.1-3.0 mix and I like it even more. Some things are simply better with Sense. I also replaced the launcher with LauncherPro (also on Stock Android) because it gives you a really nice, smooth experience. In this regard, pretty much every stock browser, be it Sense or stock Android have failed thus far.

    @Brian
    Strange that Brightness, Airplane Mode and Screen Rotation is missing, as it is included in Sense 2.1 (for example Desire S). But you probably already knew that, as you listed exactly the 3 things that are included there... :-)

    Aosp ui is pretty archaic compared to touchwiz/sense, it lacks a lot of features that makes the phone more user friendly to the average person.
    Compare the aosp lockscreen to the sense3 lockscreen, which do you think the average person would want? Compare the widgets from touchwiz4 to the widgets of aosp... oh wait there aren't any in aosp. Catch my drift? Majority of users aren't like you and me that want a plain aosp/cm7 phone, so sense/touchwiz will never die, top selling phones will never be plain google aosp phones because that's not what majority of the public wants.
  • JasonInofuentes - Monday, July 4, 2011 - link

    I think it's important to keep in mind that AOSP was designed with UI modifications in mind. It's not like HTC/Moto/Sammy/LG/Lenovo/Sony got their hands on source and went to work altering it against Goog's wishes. They wanted to be supportive of modifications to the OS from corporations and amateurs alike.

    Yes, the course was lost as manufacturers delayed updates in order to implement their UI, and some of the UIs were buggy, but then again lots of popular custom ROMS are buggy and users still love them. The point is, if there's value added, which in the case of Sense 3.0 and, by reports, the new Blur then it might be worth the cost to many. But devs should work with Google to make sure that their skins add without being too deleterious. Where I think all OEM devs should back off is in integrating social media streams; unless your implementation is decidedly better than the best social media apps then it's likely going to be a redundant, unwelcome presence.

    I don't think I've ever used the search button in previous devices, but I guess that's personal preference.

    I tried out the Sensation before buying the Galaxy S2. There was absolutely no contest. The S2 felt snappier browsing the web (A9 is 25% quicker clock for clock vs. A8/snapdragon), much lighter and nicer to hold without feeling cheap or creaking and I thought the screen on the Sensation was fairly poor in comparison. On top of that the S2 will play absolutely any video you throw at it, I'm told it'll even play 1080p mkvs and my 720p mkv Avatar makes people's jaws drop on the S-Amoled+ screen.

    The Sense launcher is nice, but I use Go Launcher EX, which has most of the features of the Sense and is almost infinitely customizable. The Sense lock widgets screen looks nice, but is useless is you use pattern or pin lock.

    Both great phones, but the S2 to the more rounded device for me.
  • piroroadkill - Friday, July 1, 2011 - link

    Good point on the video compatibility.
    It best bloody play 1080p mkv though, since my dirt cheap chinese tablet (<$200) can play 1080p mkv without any pauses.

    That's one thing a lot of the top tier devices miss, and I agree that that actually swings things in favour of the Galaxy S II..
