HDV slow motion issue?
HDV slow motion issue?
The company I work for recently upgraded from DVCam to HDV. When ever I do any slow motion the video stutters and strobes like crazy when out put to DVD and played on a CRT TV and even a Plasma display. The Strobe is not evident at all on the Mac monitor.
We are cutting in an HDV timeline and then dragging that timeline into an DV NTSC timeline as most of our other elements are still in standard def. The Shift fields filter automatically applies itself to the timeline. I tried a test with +1, –1, none settings on the shift fields filter. And I tried motion blur with a setting of 4. The –1 and none settings seemed slightly better but still very steppy. Slowmos varied from 25-50%.
Of course it looks smooth on the Mac display.Any suggestions?

Hi Richard,
This is one of the FC bigger bugs: Shift-fields can not live together with Speed Changes/Blend Frames.
You need to nest the clip with the Shift-fields, then change the speed.

When you say Nest clip with shift field. What exactly do you mean? Is it add the shift fields to the master clip? As well I am cutting in an HDV time line and then dragging it into an SD time line so it adds the shift fields filter by itself.
Please expand on this solution.Thanks

Richard,
Your first mistake is editing in HDV. It’s a TERRIBLE format for editing. You’d be much better off capturing your HDV material to ProRes.
Your second mistake is trying to do a decent speed change in FCP. It sucks for that. Send the stuff to be retimed to Motion, and use the Optical Flow settings.
Have a wonderful day.

Hi Richard,
As I mentioned, when you make a speed change (with frame blending) to a clip that have the Shift-fields filter applied, FC goes nuts and is unable to control the field order.
Before to apply any speed change to those clips (with the shift-fields already on them) , you need to nest them.

Hi,
Could someone go into depth more about the nesting of clips? I have the same problem with my slow motion in FCP (HDV), unfortunately no access to the other outside programs. Thanks for any input, I see this is a common issue. -
I have the same problem with speed changes. I shoot on P2 at 1080 50i and edit on a DV PAL timeline, even nesting the clips didnt help. Is there a better workflow I should be utilizing?
Thanks
