Converting HD to SD
What is the proper way to convert my HD footage (1080i60 shot on a Sony HDR FX1) to SD? Do I just capture it as HD then edit on a 4:3 timeline? Or is there an actual conversion I need to make?
Thanks!

HD is upper field first, SD NTSC is lower field first. So the footage should be converted before you edit it, or after you are finished.
With an AJA Io HD or AJA Kona board like we run here, we simply capture HD, edit HD, then downconvert to SD in realtime during the output.
What’s your output? If it’s DVD, just edit HD and let Compressor downconvert that to SD when you make the MPEG-2.

Thank you Walter. DVD will be my final product. So if I render my HDV sequence to MPEG2 it automatically will do field conversion for me? So basically I won’t anything to worry about?
Also, now what about when I render a Blue Ray version of the project? Do i need to convert anything or is automatically done in compressor?

Compressor cannot be trusted 100%, once in awhile I get field order jitter because it didn’t auto detect the field order.
You test it by watching it on a crt monitor.

I read your post but I am having errors in compressor when I try compressing to SD or HD – if I try Advanced formats and use the HD 1080i60 compression I get a
“Failed: QuickTime Error: – 50” message
and if I try SD – Mpeg 2 I get
“Failed: QuickTime Error: – 0” message
