Does my AVI contain interlaced content?

Hi,

There has to be an obvious solution to this, but I'll admit I haven't found it yet. I am making a home movie on DVD and a friend gave me a few AVI files that he captured on his digital still camera (don't know what brand/model). It uses the MJPEG codec and is 15fps so it definitely isn't NTSC or PAL so I'm assuming that the video is NOT interlaced, but I haven't been able to reliably say "yes" or "no". I'm not worried about quality on these segments cause the quality is already bad - but I just don't want it stuttering during playback after I encode it.

Is there any tool, or any rules of thumb which would give me a clue as to whether or not it is interlaced?

Thanks for any info,
Rob

Open with VirtualDubMod. View at 100 percent. Do you see interlace comb artifacts? I've never seen interlace video from a still camera. It also wouldn't make sense at 15 fps.

Thanks - that worked ... I never realized you could actually see the fields withing VDub... Then again I never blew it up that large.
