We shot 60i with 1/30 shutter by accident and it looked exactly like the 30p 1/30 shutter footage from the HDR-FX1.

When you shoot 60i 1/60 shutter it is very different from 30p 1/60 shutter. The interlacing is very much there.

I don't know how Sony does the CineFrame 30 stuff in this camera, but it works.

I shot the same images at 1/60 using cf 24, 30 and non cineframe. I couldnt agree with you more.

George,

60i 1/30 has no interlace and lots of motion blur.
60i 1/60 has lots of interlace

CF30 1/30 has no interlace and lots of motion blur
CF30 1/60 has no interlace and little motion blur

60i 1/30 and CF30 1/30 look exactly the same.

60i 1/60 and CF30 1/60 look VERY different

CF24 is a waste of time.

What don't you agree with? I can upload some stills.

Uh, he said "I couldn't agree with you more". That means he agrees with you.

I gather from this that CF30 1/60 will be the way to go for most of us then?

Have you used (or seen footage from) the JVC HD10? The JVC at 30p 1/60th has no interlace and little motion blur, are you saying the Sony does an equally good job with their simulated 30p (Cineframe 30)? If so that is great, I was really upset to see Sony go with 1080i instead of 720p, but if this is the case that removes my only real complaint about the Sony.

Final question; when you use CF30, do you actually end up with a file that is progressive (1080/30p)? When I bring it into my editing program will it show it is a 30p file?

Thanks,

Ben

Hi Dustin

I totally agree with you. Sorry if I wasnt clear. cf 30 is terrific. cf 24 is really wierd and I havent found a way to effectively use it. Maybe for head shots with little to no camera movement.

Sorry about that George. I totally mis-read your post.

I haven't compared the footage to an HD10U because I don't have one. I do know that I haven't seen any of the chroma noise that I saw in the HD10U.

I think the CF30 1/60 is what I will use most of the time on this camera. Motion is better on 60i, but CF30 looks great.

When we shot the ocean with CF30, it looked odd, like it was in slow motion. At 60i they looked correct, but very much video.
