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.

do you have to post the review as soon as the NDA is lifted? If that is not the case, why not wait a few more days to share the final review? I enjoyed reading what is present right now but was just wondering. Also would you recommend waiting till Win8 tablets if I have no necessity for tablets this very moment?bupkus - Thursday, December 1, 2011 - link
Also would you recommend waiting till Win8 tablets if I have no necessity for tablets this very moment?Sounds like you answered your own question.

Yes, they have to post as soon as the NDA is lifted because first reviews = page hits.Anand Lal Shimpi - Thursday, December 1, 2011 - link
It's generally a good idea to have something up when the NDA lifts (plus, if you don't have something up when the NDA lifts manufacturers may think you don't need to be sampled alongside those who do post when the NDA lifts). In the PC space this is rarely an issue since we normally get 7 - 40 days with a product before the NDA lifts. In the mobile space it's a much bigger problem as many reviewers seem to be ok with a 2 - 24 hour testing period (+time for writing). As I mentioned in the article, I fully expect this to change over time (and I'm actively campaigning for it to change), it just doesn't help when ASUS contributes to the problem. To ASUS' credit however, I don't believe this was ultra intentional but it happened nonetheless.The tablet space is one area where you should wait if you can. The segment is evolving too quickly.
Take care,
Anand

You have to give them a pass though, clearly their #1 goal is getting it out to stores before Christmas and they had to compress their entire release schedule, not just the delay between shipping it to reviewers and lifting the NDA.Why not do a first impression and an in-depth review after a few days?

That seems to be the better way of it. The problem with mobile launches is that they do occur very hot-off-the-press in terms of final software/hardware release. They occur so often every year and there's such a race to compete that even if you got a sample very early on, it likely would not have had nearly as complete a software stack.Anand Lal Shimpi - Thursday, December 1, 2011 - link
This was our first impression post :-P The replacement Prime arrived this morning and I've been working on it since it showed up :) Expect more in the coming days.Take care,
Anand

Sadly, they do. The reason for this is to get the page views. Yes, a more thorough review would be great, and it'll come. For now though, they have to keep up with the competition of suffer the lost visits.Anand Lal Shimpi - Thursday, December 1, 2011 - link
I felt like I did as best as we could given the WiFi issues of the test sample, more is coming though...Take care,

is it only me that hates that ugly black border around virtually every tablet since the iplod?I mean what wrong with having screen to the edge? Somewhere to put your fingers? pfft ill trade that space for working area and hold it at the edge, or if not make it smaller for my pocket
