Hi am not offending by your questions, i have used after effects before but I am not a professional.
the video reolution is 1680 x 1050 (the same as my screen) its 40 seconds long. The original .avi is only 30MB so it must be really compressed although it looks great, I import the video into a new after effects project, drag it into the composotion button to create a new compisition, I then render the movie without changing anything, my render settings are set to “Best Settings” and my output module is set to “Lossless”. after rendering the video the new video size is 40GB and looks terrible, its very jumpy and appears as if pixels from different frames are mixing in together and overlapping.
as far as pixel aspect ration, I have not changed anything so whatever the dfault is, but after its rendered that shouldn’t matter anyways right?
THANKS!!
