Re: King 7S 3D phone on sale!

I down-loaded your 3d movie clip Scroll ( 1920x1080 60fps 9Mbps ). Thanks.

I played it using built-in 3d player in the King 7S.

There is some judder in the movement of the image as it scrolls sideways.

I played it using a down-loaded app MX Player ( free app )  in the King 7S.

The above clip played as 2d did not Judder. ( I also down-loaded VLC player for 2d clips but found that MX player was better in terms of reducing Judder )

I made a copy of the above clip, but this time made it 1920x1080 30fps 9Mbps.

The clip is not slowed down, it just has a frame rate of 30fps instead of 60fps.

I played this version on the built-in 3d player in the King 7S.

Again there was some judder ( about the same as before )  in the movement of the image as it scrolls sideway. So having a clip at a lower frame rate is not necessarily a fix.

I made another copy of the original Scroll clip , but this time made it slow down by a factor of 2, and also made the frame rate 30fps. This means the rate at which the image scrolls sideways across the screen is now at half the speed of the original. I kept the data rate at 9Mbps. Result - the clip did not judder in the movement of the image as it scrolls sideways.

Conclusion from this is - if it is a 3d clip try not to pan sideways at a fast rate.
