Interesting JVC HD250 experiment.

I just thought I'd give you folks a little heads-up. A couple of weeks ago I posted links to some frame captures from my HD100. I've been using it with a Cinemate-15 to telecine some old 8mm footage for my current project. Someone from JVC contacted me and said they found the frame captures interesting, but wondered if the new MPEG compression engine on the HD250 would do a better job of encoding the grain structure than my HD100. I just got tracking information from JVC. They're shipping me out an HD250 so I can do some tests. It's pretty exciting for me and I think they're looking forward to seeing the results, as well. I was told that they've done video-to-film tests, but never seen film to video tests on this line.

Anyway, I just wanted to drop everyone a line and let you know what's going on. JVC is not only listening to what we're doing with their products, they're very proactive about getting involved.

From what I have seen, the blue alpha channel on the HD-250's super-encoder is much better and does reduce the grain.

The only thing I am waiting for, and it is minor, is a 2.35:1 aspect ratio guide in the viewfinder like the Xl-H1 has.

Wow thats Great Robert!

I've been using my HD100 to do film transfers as well.

8, Super 8 and 16mm all through a cinemate-20

Have you noticed though that the chromatic abberation shows itself on some shots? (and the blue on one side, gold on the other abberation as well?)
You only see it on certain films and i don't know why.


It happens where dark meets bright. But not all of the time. and its worse near the edges than the middle. The stock lens has a tendency to bring out a "blue glow" as well at certain times.

I find myself having to put the camera in black and white mode when doing black and white transfers otherwise the CA shows up and thats not right having any color on black and white film.

Other than that though the capturing from the cinemate-20 is really great.

Hi Steve,

A 2.35:1 safe area viewfinder guide is available in the GY-HD250, as well as the GY-HD200. This is covered on page 89 of the users manual.
