Sony A5000 - movie interlanced or progressive.

I am interested to buy Sony a5000.

Spec:

1920x1080 60i (interlanced) or

1920x1080 24p (progressive)

 

I am interested only in 1920x1080 30p. I have read review that sensor of a5000 provides 30p stream, and 60i is created out of 30p in such a way that:

- odd lines from 1st frame of 30p stream makes 1st frame of 60i steam;

- even lines from 1st frame of 30p stream makes 2nd frame of 60i stream.

- odd lines from 2nd frame of 30p stream makes 3rd frame of 60i stream;

- even lines from 2nd frame of 30p stream meaks 4th frame of 60i stream.

 

In other words 1st and 2nd frame of 60i stream at not taken with delay 1/60 th second, they were captured at exactly the same time and are coming from single frame in 30p stream which sensor provides to CPU. This suggest that conversion 60i -> 30p is possible without any motion compensation and quality loss.

 

Can somebody confirm or deny this? Thanks.

Hi SBC_Canon,

welcome to the Sony User Community Forum..

 

I have been unable to locate any information on this but you may be able to check this if you can get your hands on a a5000..

If you can try moving the a5000 from right to left, or left to right it doesn't matter, whilst recording then look at the still image afterwards, if you can see motion blur then the recording is probably interlaced with half resolution per frame or if you can't see any motion blur then the recording is probably the same image is used for both frames..
