I've posted some HD video test clips specifically to stress test Nexus 10's video playback capability. The 2-minute clips all have the same content, and were taken from TimeScapes, AFAIK the only publicly-available film in 4K resolution.
The first two entries below are reference 1440p and 1080p clips, with selected sequences losslessly cut and spliced from the 30" HD Download and BluRay sources, respectively. (Audio was reworked for continuity and recoded to AAC 2.0.) The second two entries are "rip" versions of the reference clips, encoded for fidelity and small size. They should be indistinguishable from source, and are for demo rather than testing. The last two are the 1440p_60f clip (24->60fps upconversion using 32322 frame dupe pattern), intended as a "Kobayashi Maru" test, and the 1440_10b clip for 10-bit testing.
Clips are muxed to MP4 container for native (hardware-accelerated) playback. You shouldn't need to use a 3rd-party player except for the 10-bit clip.
Please test with a clean configuration, ie no running background tasks. Please provide feedback on:
. Smoothness of playback of each clip.
. Any visual difference between 1080p clip and 1440p clip.
. Tablet model (if not Nexus 10).
. Video player (if not native player).

1440 -- 2560x1440 clip from 30" HD Download source, 18Mbps; use for native-res playback stress-test
1080_BD -- 1080p clip from BluRay source, 35Mbps; use for visual comparison vs 1440p and bitrate stress-test
1440_demo -- 1440p/1080p clips re-encoded for fidelity & small size (CRF20, veryslow preset); use for demo
1080_demo
1440_60f -- 1440p clip converted to 60fps and re-encoded at CRF19; use for "blue sky" test
1440_10b -- 1440p clip re-encoded at CRF21 10-bit; use for 10-bit playback test
NB: TimeScapes is AFAIK the first commercially available video at 4K resolution. It's a collage of naturescape and skyscape sequences using time-lapse and slo-mo videography. It's mostly the work of one guy, Tom Lowe. If you find the clips interesting enough to obtain the whole 48-min video, please support the creator with a purchase. The film is available at http://timescapes.org.

Great resource files. Thanks for sharing.
Now what I need is just a Nexus 10...

---

Ill test these and report back soon

---

It's impossible that it will play 1440p 10bit especially when devices around that power can't even play 720p 10bit properly. A better test would be 1080p and 720p 10bit.

---

Did my own, test, not happy about the performance. the file is a 1080p short clip encoded in H264 [email protected], bitrate 20Mbps, there were frequent drop frames, not smooth at all.

---

I've downloaded 1440_60f -- 1440p clip converted to 60fps (32322 dupe pattern) and re-encoded at CRF19, use for "blue sky" test and I can't get it to play in the stock player or mx player.
Any ideas?

Infact I can't playback any of the files? Any ideas anyone?

I'm very interrested in the thread as I attend to buy the Nexus 10 for movie playback (1080p mkv file ).
Can you try with BS Player ? on my Galaxy S3, BS Player works way better than MXPlayer (on the bird : http://cybernetnews.com/xbmc-high-bitrate-sample-videos/, mkv @
20mbits).

Still won't play the files from above. I'll download the sample above and try that.

My desktop computer struggles with 1440p/10bit & @60FPS, so I don't expect a mobile device to play it. But playing popular formats on 1080p smoothly will make or break the deal for me. If there are struggles, I'll just wait for the 5450 / T658 Sammy tablet next year, hopefully coming as a Note and before March. The Nexus 10 is a great package make no mistake, but Samsung will certainly have a more optimized HW for his in-house product.

I've tested a recording off my S3 camera and it plays back using the hardware encoder fine, just downloading this birds sample to test.

Works fine in BS and MV players. Yey :good:

I'll join the test club once I get home, left my N10 at home today so I wasn't distracted at work :angel:

---

Guys can anyone confirm if it plays 10bit 1080p mkvs smoothly? i wanted a quad A15 because i know quad A9s can't handle it (at least not at the stock frequencies current flagships have) but this is what we got and i'll have to live with it

1080p 10bit MKV to test out - http://android.tnonline.net/Software/Video/Hi10P Software/hotd-op-1080p-hi10p.mkv
720p 10bit MKV to test out - http://hotfile.com/dl/148950242/e652ee9/
These videos should be SW accelerated because nothing should be able to HW accelerate 10bit videos. So don't be surprised if it DOES play slow. In fact, you should be surprised if it does play nicely.
If it doesn't play nicely, this isn't a problem with the Nexus 10; it's a problem with the video format not being supported too well (and don't worry if you don't watch anime - it's a very niche kind of encoding).
I'm expecting 720p 10bit to play and 1080p 10bit to not play.

:victory: thank you !
So at least it should be able to play almost all 1080p mkv (8bit of course) smoothly

These samples are intended for stress-testing, to determine the boundaries of N10's playback capability, and thus aren't designed to be the typical "downloadable" variety. I'm not interested in software playback, since that depends on the video player's efficiency and isn't relevant to the hardware.
FYI, on my ancient test rig, an E5200 C2D and using only GMA graphics, play back is smooth for both the 1080p BD and 1440p normal. The [email protected] stutters once every few seconds (hence its "Kobayashi Maru" designation,) and the 1440p 10-bit stutters a couple of times. I expect a PC with a discrete GPU to be able to playback all these clips smoothly.
Please test the baseline files (the 1080p BD and 1440p source) before continuing with the "harder" clips (60fps and 10-bit). You should expect N10 to smoothly play both source files. If it is that N10 can't play the source files smoothly, I'll upload a "rip" version of those files at a smaller bitrate. FYI, the 1440p source file is already in the "rip" range, as its 18Mbps is equivalent to a 1080p rip's 10Mbps (1440p has 78% more pix than 1080p).

---

Yeah, sadly that's what i think that will happen and as i watch insane amounts of anime that's a big deal for me, well at least it will do better than my TP, i wonder if the damn GPU makers will ever do anything to support 10bit HW decoding as they look much better.and it's bad to be forced to use 8bit in a screen as good as this one.

1440 -- 2560x1440 clip - Played Smoothly
1080_BD -- 1080p - Played smoothly
1440_60f -- 1440p Jittered all over the place, but played
1440_10b -- 1440p Didnt play
Video on the way

---

@italia0101
Can you discern any detail difference between the 1080p and 1440p clips?

---

hm difficult question, iv just looked at them both again and id say the 1440p looks better, but you would be hard pressed to see a major difference, well at least i cant..
Edit- the 1440p looks better ..

Can you try 1080p and 720p 10bit samples? :x
