slow motion hdv
Working on FCP 5.1.4 and trying to slow down HDV footage from between 75% to 35%. I notice that unlike SD, HDV creates a “strobing” or “stuttering” image in slow motion. Is anyone else experiencing loss of quality in slow motion? I realize that slow motion is problematic and will cause loss of quality, but what is going on with HDV that makes it so distracting? Should I turn off frame blending?

It’s called 25:1 MPEG-2 compressed, 4:1:1 color space footage. In other words, you’re working with incredibly compressed footage and now you’re trying to slow mo it. HDV does not slo mo nearly as well as DVCPro HD material in our experience.
You’ll want to try turning on some motion blur as that can help the slo-mo.

thanks. I was searching previous posts but must have missed this one. So, is FCP the best program to slow down HDV? Will I have better results with AE or any other program / plug-in?

Within FCP, use the Frame Blending and play with the Motion Blur settings.
If you have access to Boris Continuum Optical Flow, you can get better results. Not sure if After Effects will do a better slow mo than FCP, never tried it.

Although SHAKE does not (according to the documentation) support HDV, there are ways of getting your footage into a SFIleIn node — after which there are several choices for doing frame rate modifications. I have achieved some excellent results with interpolation — and without all that blending and blurring that makes the picture into one big long smear. Expect some different behaviours of course, with different kinds of image flow — that is, whether it was a still subject that you’re doing a camera move on, or a static camera shot of a highly dynamic scene, or a combination. Expect to try several parameter adjustments, and some interlacing woes. I can’t say I truly grasp what is going on with HDV in terms of whether it is actually interlaced, or segmented or semi-sequential or what ever, but the interlacing that I became familiar with in 525iSD it AIN’T.
