Don,

I was intrigued by method 3 since it would save the extra rendering step.

-Edit in XDCAM EX 1080 60i sequence (w/render settings to ProRes HQ)… but don’t render.
-Export Self Contained file in SD Codec of choice (I chose Unc 10-bit anamorphic).

The resulting SD file looks great playing back in Compressor (properly playing back in 16:9), but in MPEG Streamclip, it is squished to 4:3.

To convert to MPEG2, my Compressor settings were 6.2Mbps 7.7 max. 2-pass 16.9 AUTO field (the orig is 60i).

The results looks awful. In both Compressor and MPEG Streamclip, the m2v file plays back stretched out in a 16:9 frame (because of the stretch, the sides are cut off… as though a normal 4:3 file were stretched to fill a 16:9 frame).

So, I tried the same Compressor settings except with with a 4:3 aspect.

The results were a properly centercut 4:3 image.

Clearly, I’m doing something wrong. How can I use your workflow it get a 16.9 anamorphic MPEG2 file?

Thanks for your response in advance.

Bob
