I have an video, however It's mp4 but It's name contains "HD.mp4" video. The duration of video is 4:26 and its size is 45.12 mb. I'm using HTC explore which is unable to play it despite with MX Player.Its play with lag. So my question is that which Mobile can play such type of video as I'm gonna buy a New smartphone.so What it takes to play this kind of video,I mean the resolution,processor,RAM, gpu and other things.
Let's take a look at some mobiles:
1. HTC desire 300
-1 GHz Snapdragon 400 Dual Core Processor
- 512 MB RAM
reoulution- 480*800

Samsung galaxy core:
- 1.2 GHz Dual Core Processor
- 1 GB RAM
resolution- 480*800

and nokia lumia has the same spec as HTC desire 300 but it can play 720p video.
so which mobile can play my video as I mentioned above

HD-Ready or just HD means that the resolution is around 1280x720, or 720p.
Full-HD, or sometimes HD, means that the resolution is around 1920x1080, or 1080p/1080i
So you'll have to buy a phone with higher resolution if you want to be able to play these videos, 480x800 isn't enough.
But if you really want one of the above smartphones, I'd recommend getting the Galaxy Core.

High-definition video is video of higher resolution than is standard. While there is no specific meaning for high-definition, generally any video image with more than 480 horizontal lines (North America) or 570 lines (Europe) is considered high-definition. 720 scan lines is generally the minimum even though many systems greatly exceed that. Images of standard resolution captured at rates faster than normal (60 frames/second North America, 50 fps Europe), by a high-speed camera may be considered high-definition in some contexts.

HD means 720p for films
full HD = 1080p
