Time remapping FCP
I’ve searched in the forums for an answer to my problem but didn’t find one so I hope you can help me!
I want to slow down a clip that has the following format:
Vid Rate 29.97
Frame size: 720 x 480
Compressor: DV/DVCPRO-NTSC
Field Dominabnce: Lower (even)
Pixel aspect: NTSC CCIR 601In the FCP motion tab (Time Remap) I enter the following settings:
Speed 50% / Constant Speed / Frame Blending ON
Then I export the clip as a Quick Time, using the DV NTSC 48Khz setting.
The Quick Time movie looks great on the computer but when I burn a DVD and play it on a regular household DVD, the clip looks very jumpy, not smooth, with a strobe effect.
I’ve tried different settings to export the clip as a Quick Time, but all give the same result.
What could I do? Why can I only see this problem during playback in the DVD and not on the computer?
Thanks!!!!!

“Are you looking at a monitor while you’re working in FCP? That’s essential.
Most likely, your footage is interlaced, and slowing the image causes the flicker. If you use a monitor with your FCP system, you can detect the interlacing problems as you are working, and attempt to work around them.

Hi,
No I’m not using a monitor but will definitely follow your advice, thanks.
Would you say that I should de-interlace my clips before slowing them down, or do you have any suggestions as to how I can “attempt to work around them”?
Thanks

You’re on the right track with the deinterlance…
It’s been a while since I’ve worked with interlaced footage, but I’d try “Deinterlance” or “Motion Blur”.
Also, if you’re handy with Motion or After Effects, you may get better results.

1. Right Click on the Clip > Send To > Motion
2. In Motion, Select the Clip.
3. In the Inspector, go to the Timing controls.
4. Choose Optical Flow in the Frame Blending parameter.
5. Save
6. Return to FCP
7. File will update > RenderYour speed effect will look much better this way. Definitely use a video monitor or the best TV you’ve got around the studio. If not, check the render with your Canvas set to 100% precisely.

Kevin’s method works well, but a warning, if your master clip is very long, Optical Flow can take hours, literally, as it will analyze the entire clip. I usually find the section I want to retime, copy it with handles and send that to Motion.
Have a wonderful day.

I fixed the problem by using a De-interlace filter + Motion Blur + NO Frame Blending. It worked fine for what I was doing. Apparently there are many ways out of this problem. Thanks all.
