Footage shot on DVX-100B: is it progressive or interlaced?
on Jul 13, 2010 at 8:45:58 pm

Hello everyone,

I have some footage from someone that was shot on a DVX-100B and captured on a Focus FS-100 hard drive in DV format with a MOV file extension. I'm wondering: is there an easy way for me to tell if this footage was shot in 60i or 30p?

Thanks!

load into your NLE and see what it is there.... It would be either 30p, 24pA or 24p standard.

[Mike Tomei] "...is there an easy way for me to tell if this footage was shot in 60i or 30p?"

After Effects can make short work of telling the difference:
  • Create a new AE project, and import the footage
  • Select ONE clip, and interpret it (File>Interpret>Main) as lower field first.
  • Use the "remember interpretation" command (also in interpret footage) on that clip.
  • Select all the other clips, and APPLY the interpretation.
  • Create an NTSC DV comp, and set the frame rate to 59.94.

When you add a clip to this comp, find a section with motion in it, and step through it frame by frame. If the motion changes on every frame, it's interlaced (60i). If it changes on every OTHER frame, it's progressive (30p).

you can also tell visually by going frame by frame in any editor- not everyone has AFX. :)
