Unpredictable Render Results?
Good morning all,
We have recently noticed than when importing 10Bit Uncompressed QuickTime files into AE (7.0 Pro) they are automatically placed in a composition at a position of 340,243. All these files originate/captured from NTSC Digibeta via Telecine/35mm transfer. Since the rendering of this material involves fields would re-positioning the source files position on the X axis say to an even 240 or 242 improve render results?Also we have always found it challenging to render these files from AE with out taking a noticeable quality hit even when re-rendering these files to non-compressed codecs and even the same codec as the source file.(usually

Many thanks David for taking the time to reply. Yes….I beg your pardon I did mean 360,243 and the footage is 720×486. Regarding fields we seem get the best results by interpreting separate fields off & rendering with out fields. Is this incorrect? Do I understand then that the position of the footage is irrelevant as long as it’s interpreted correctly?
Interesting regarding color space. Is there no capacity within AE for conversion??Thank you,

if you have interpret fields off and render without fields, you are actually maintaining your fields.
if you have interpret fields set to the apropriate dominance (lower in this case) and render without fields, you will de-interlace your footage.
if you have interpret fields set correctly and render with fields (set the same dominace as orig footage) then you will get back proper field renders. this would be the better way to work. you would like to ‘deinterlace’ your footage in ae to apply many effects because fields can create unexpected or unwanted results, particularly when keying. but then you would like to reinterlace when you render to maintain the smoothness of motion that your original footage had. using the appropriate settings in ae allows ae to handle the conversions for you, and minimize the hastles on your part.
