I recently switched from NTSC-DV 4:3 to HDV and mixed codecs and am stumped as to which sequence preset I should pick to set-up a new timeline and if I am interpreting correctly. I will be shooting mostly with an FS100 but also a D7000, so the HDV will slowly go away. I have actually mixed 1080p24 H.264 with 1440 60i HDV with 1080p30 ProRes and output/rendered it all as 1080p30 (29.97) mp4, after interpreting everything as 1080p30. But I (oddly) I had to put the 1440 60i back to its original format when it looked squeezed prior to rendering. Can anyone explain what I'm seeing and give tips on proper workflow for this?
