Bob (the one who originated this thread) and I work together. This is what we found out:
– I was rendering with the correct pixel aspect ratio
– He was importing with the right pixel aspect ratio
– I was not using an Avid codec, downloaded them, but they did not solve the problem. However, I will still use them.
– I was using the “File – Interpret Footage – Pixel Aspect Ratio – D1/DV NTSC (0.9)” for all of my files (photoshop and illustrator – which were square pixels). Now, I do not interpret my files and leave them in their square pixel aspect ratio.
– I now use the “View – View Options – Window – Pixel Aspect Ratio Correction”. This allows me to see exactly what I am rendering for Bob.
– We now have circles!!!!
So, in short, the solution was not to interpret my files, just leave them as square pixels – and, to change the view options to see the pixel aspect ratio correction.
