ASUS Eee Pad Transformer Prime & NVIDIA Tegra 3 Review
by Anand Lal Shimpi on December 1, 2011 1:00 AM ESTVideo Playback: Blu-ray Quality in a Tablet
One of the biggest issues with Tegra 2 based tablets and smartphones is a limitation that prevented hardware accelerated decode of any high profile H.264 video content. You could still decode the video but the additional stages of the decode process were left to run on the CPU, which in turn resulted in substantially lower battery life. NVIDIA has completely addressed the problem with the Tegra 3's video decoder, which is now capable of decoding 1080p H.264 high profile streams at up to 40Mbps.
The Honeycomb video player (Gallery app) will play .mkv files by default but if you want to throw on a .m2ts file you'll need to grab a third party player. DICE Player for Android supports Tegra 3's hardware acceleration, making it a good option if you want broader file compatibility.
Android File Transfer won't push over a file greater than 4GB so the first thing I tried was ripping a portion of A Quantum of Solace (BD) and sending over a 40Mbps High Profile 1080p MKV of it. The resulting 10 minute segment was 2.8GB in size and played beautifully on the Prime. There were no dropped frames and no hiccups, it just worked.
External NTFS volumes are supported and the sdcard file system supports files greater than 4GB in size, so I copied a 15GB 1080p Blu-ray rip of A Quantum of Solace from a USB stick to the Prime. I had to use DICE Player to get audio but otherwise the clip just worked. The biggest pain was copying the huge file across, but it'd be quicker and less painful than a re-encode on most systems.
To really test my luck I threw a few of our media streaming test files at the Prime. Our 720p60 test file worked perfectly, while our 1080p60 test case was mostly smooth with the exception of occasional slowdowns. I tried playing back a 1080p30 VC1 file however I couldn't get it to play back with hardware acceleration. Some of the more exotic combinations of features and file types wouldn't work, although I suppose that could be the fault of the playback software.
As far as I can tell, Tegra 3 and the Eee Pad Transformer Prime in particular are capable of playing back 1080p24 Blu-ray class video. Total NAND capacity is the only thing limiting us from just dumping a raw Blu-ray rip onto a tablet and playing that directly. Pretty much any HD rip you make yourself or find online will likely work. You may still need to invest in a good third party player to ensure things like subtitles are properly supported however.
I'm pleased with the state of video on the Prime. It's not HTPC level, but we can finally play really good quality video on an Android tablet. I suspect it'll be one more generation before we get tablets (and associated software) that will just play anything you throw at them.

Sorry Anand, but could you clarify what you mean by "getting actual work done"?I don't expect the Transformer Prime to be running Photoshop (although Photoshop Touch is available?) or any intense apps. But is it a "good enough" laptop for a general user?

Browsing the web is still faster on an MBA/ultrabook, pages load quicker, you can open multiple tabs and load them in the background more effectively - you can switch between tasks quicker (cmd+tab/alt+tab is still infinitely more responsive than what you get with Honeycomb's task switcher). You can get writing done on both, but multitasking and being productive is just easier on a MBA/ultrabook.Now both of those comparisons are ~2x the price of the Prime. Compared to a netbook, I'd definitely get the Prime.
Take care,
Anand

Alt-tab was one of many things that impressed with my OG transformer -you don't use the honeycomb task switcher because you just alt-tab with the keyboard!I have to say asus really get it on that: I don't know for sure if it's asus or google , but the others that warm by keyboard-loving heart are ctrl-t for a new tab in browser and ctrl-w to close a tab.
Also re zooming, I can't speak for the prime, but the original will pinch-zoom with the touchpad.
Thanks for the great review -got to find an excuse to upgrade now!
(you're still right about an ultrabook but it feels like asus are so close...)

Ahaha -- I managed to use my Transformer all this time lamenting the lack of keyboard-based task switching but without actually trying Alt-Tab, which of course should be the first thing to try. Thank you, agt499.twotwotwo - Thursday, December 1, 2011 - link
I have an original Transformer that I've used as my work machine a few days, and I also used a netbook as my only machine for six months. Transformer's very much a tablet and not a computer, because of Honeycomb. The bad task switching and other annoyances -- different text-editing shortcuts, lack of a full Docs app, lag editing paragraphs in the browser, etc. -- mean it's fine for the reading/consumption that folks do on tablets (and better for e-mail, chat, some writing or notetaking, and SSH if you do that) but, for me, it's worse than even a netbook at other stuff.If you're thinking of it for tablet-y (or mostly tablet-y) uses it's a slam dunk: it's a tablet, great screen, mobile OS, monster battery life even vs. netbooks.
If you want a computer, you want a computer. Besides netbooks and ultrabooks, there's the Core i3 ULV x121e (and others like it soon, I hope) in the middle.

Why exactly don't we expect these sorts of machines to be running photoshop? Very complex versions of photoshop ran just fine on single core P6's with a 1024x768 monitor.Now we have four GHz+ cores, CPU speed really can't be much of an issue. Screen realestate might be, but that's manageable with alternate layouts.

I think the biggest limitation with programs like Photoshop on small form-factor devices -- including ultrabooks -- is the display resolution. Now granted, for a lot of simple photo editing, that won't matter -- and in fact, that's what Photoshop Touch is for -- but for more professional level content, the displays may just be too small and low-resolution to get the job done.But you're right, the processing power is there nowadays.

I always assumed it was an x86 issue. Since there's no x86 support in these devices Adobe will not re-write/compile the software - kinda like how it took years to have a native x64 flash player (and not a x86 kinda running in an x64 browser).I would think it's simply a matter of laziness/unwillingness (profit margin?) on Adobe's part.

Photoshop Touch and a suite of other tools is coming to Android within a month or so. Adobe wants to grasp opportunities; but just porting a mouse-and-keyboard application to Android isn't the way to go about it.ctrlbrk - Thursday, December 1, 2011 - link
Anand, thank you. I have been eyeing this tablet for a long time now.I want to know your impressions of how it feels in your hands, weight wise? For bedroom surfing, email, youtube, etc -- but not movie watching -- is the 10.1 too big and too heavy? Is it better to get something like the Galaxy Tab 8.9?
