Hi all,

I want to implement a encoder deal with I and P frame.
So only one reference frame is stored for motion search.
Is it the reconstructed forward frame?

But the MSSG (**broken link removed**) encoder's full search function require 2 frames.

Its integer full search is based on the "original source reference".
And its half pel search (9 point related to the best integer) is based on the "reconstructed reference".

Do you think "original source reference" can be replaced with "reconstructed reference"?

Any suggestions will be appreciated!

Best regards,
Davy
 

Half Pel search is done with reconstructed reference as you interpolate the reference by factor of 2 and then do the motion search. But in Full Pel , the motion vectors are calculated on the original reference only.
