Thank you so much Tudor for you insight.
I am using Flash Movie file.
That is swf format.
Hence,i don’t have any temporal or interframe compression for these footage.
I am using AE to compile my footages as Adobe Premiere doesn’t imports flash swf format.
the preview is going smooth in AE of my compiled swf footage.
However,with the above mentioned settings (avi as my video format with xvid mpeg-4 codec) there is loss in quality in some areas and red patches develop.
hope to figure out the core reason.
Thank u so much for the guidance Tudor.
