Acer Liquid S2 photo and 4K video samples
Acer treated us to quite a surprise yesterday. It announced a new high-end smartphone – the Liquid S2 – with a droolworthy specs sheet and a number of goodies included on its feature set. One of them is the 13MP main camera which can be used to record video in the crazy-sounding 4K resolution. Actually, the Acer Liquid S2 is the first smartphone capable of recording video in Ultra high definition.

For those not familiar, 4K is what follows beyond Full HD – a video standard that will be best experienced on those new Ultra HD television sets. Seeing it supported by a smartphone is nothing short of impressive given the footage's raw resolution and how much processing power is likely required to capture or play it back properly. So naturally, we gave 4K video recording a go while playing with the Acer Liquid S2 at IFA 2013. 

The sample video that we took, captured at a resolution of 3840 by 2160 pixels, is embedded below, and to watch it at full res, make sure you pick "Original" from the list of available resolutions. However, don't draw any final conclusions about its quality. The Acer Liquid S2 unit we used during our brief testing wasn't yet finalized so future software optimizations may change how the smartphone's 4K video looks.

Is it just me or is the frame rate terrible?

Youtube is not optimized to play 4k video.

The resolution of the video is 2304p and yes if you play it in VLC and you have a half decent PC it will play it right and it is bad FPS and the quality sucks. The camera has way to much noise and it it very jerky.

Cause of the low light. Most cameras, even the HTC One and Lumia 920 lower frame-rate inside to get individual frames more light.

I'm good with 1080p 60fps .. Unless we have 4K screens on our phones. Plus I don't have a 4K TV.. Only 1080p .. When phones start to use this 4K recording we going to need 128/256/500GB memory in our phones..

h.265 will help with the storage issue. They have screens and cpu down. Now the manufacturers need to work on battery life and storage. The cost memory of flash is super cheap right now, if every consumer knew how overpriced flash memory was then they wouldn't get away with charging so much for it.

Not only that but the data speeds will need to triple or more. Also the the data caps from the providers will need to go up. 5GB will be used up in no time.... especially shared.

Tmobile unlimited 4G LTE + Text + Voice for $70 a month. Stop getting ripped off and switch. On h.265 it requires about double the bandwidth that 1080p does on h.264.

We are shifting off DSL and Cable onto fiber right now. In the next decade most people will not have to worry about data.

I agree for once... One problem, tmob has coverage issues all over my state.

Just tested mine 40 megabit down 15up I can do this all day and night because I have unlimited with no throttle, that is their LTE which covers like 80% of where I live. in places I get 4g it usually gets 10-20mbps and same for up.

That's good speeds.. Coverage for tmob is mostly 2g maybe 3g in my state.. I can't do that BUT if they were those speeds I would switch for sure.

Ya if I go out of the city it goes straight to 2G.

Hmm I don't think they have the name to be a hit in the phone space really. Plus it doesn't look great tbh.. I'm sure on more capable equipment it will look amazing.

25 seconds... 75mb... 3072p

this shiit will EAT your space

1080p eats enough space already

this is just like megapixels in photos. higher resolution doesn't mean higher quality.

i hope they don't get an idea to make a 5" 4K screen, that would be extremely dumb. but I can image it, it's all about bragging rights.

Not necessarily... 4K is only 8mpx, just imagine you have a good 8mpx picture like GS2 in motion... This will be great.

In fact, the issue here, is we have to wait for the new codecs specially made for 4K. Before they arrive indeed, 4K is useless because it will require to much space so high video compression. Maybe this Acer will use h265 (as here it is not a final software) ?
