The Stutteriness, the motion trail, the ghosting, oh the humanity!

I ran into a similar problem. It turned out to be the method I was using to capture the footage. The ghosting wasn't on the tape. I was using Canopus, and I had to make sure every little detail was set the same as the footage (in this case 720P/24 ) and that it was capturing the data stream to .m2t files. In my case, the computer was definitely capturing in-between frames, so that ever second or third frame was a superimposition of two frames on the tape, with one frame very strong and the previous frame just a ghost image. Once I got the computer making a copy of the data from the tape to the hard drive, the problem disappeared.

If, however, you're sure the images we're seeing on these JPGs are exactly what's on the tape, then all I can say is it _looks_ to me like the CCDs aren't refreshing. Did you have the gain on? Is that a silly question?

No gain at all.

These are .m2t files that were captured by HDV Rack. There was no NLE involved in the capture, they should be an exact duplicate of what's on the tape. I don't have the original tapes, Charles Papert should have 'em.
