de-interlace filter strategy
I am working with a multitude (say, 70) short (average 10 seconds to 2 minutes) clips. The image is of a dancer dancing in a black space. When I slow the speed down or make freeze frames (both of which I do constantly) the two fields jump around. The de-interlace filter corrects this. I would like to apply it to most, or all of my clips before I begin working with them, render the filter, store them in the browser, and then work with them in the viewer as I would a non-filtered clip. I want to avoid having to re-render everytime I tweak it or try something new. Is there a way to do this? Would I have to place each clip in a separate sequence, apply the filter, render it, export it and reimport it? (I am hoping to find a less labor-intensive work around). If I do have to do this, do you have any thoughts about how I should manage them in the hard drive? Just create a dedicated folder for them? Thanks.

I simply would IGNORE any flickering during the edit process until the show was done, then render, check it, do any fix-ups and render the final.
Much faster workflow than doing it a step at a time.But, yes, you could deflicker each clip, export to QT… MAKE SELF CONTAINED.
Drag each new QT into a new folder and use those clips for the edit.
Problem is, if you used any motion at or near full speed, it could look “jaggie” due to only one field being displayed
But its up to you to decide if that’s OK. -
Load all the clips into a sequence
Apply the filter to one clip and adjust the settings however necessary
Copy the one clip with the filter
Select the rest of the clips without the filter
Crtl Click the selection and choose “Paste Attributes”
In the menu that pops up, hit the check box next to filters then hit OK
The filer should be copied to each on the the clips.
Then drag all the clips back into the browser
Then, do a batch export.It would be nice if there was some way you could do this entirely in the browser but I don’t know if there is one.

If you are looking for extreme speed reductions or very high-quality slow-mo, I’ve had great success using the optical-flow stuff in Compressor and it does very good of deinterlacing as well. You could point it at all the clips and do them in a batch job, though it could take a *lot* of compute time. If this is of interest, say so, and I’ll post the workflow.

Thanks everyone. I have more questions but will respond to each listing separately since I am guessing that is the most likely way that each of you will get my reply. (I’m new enough at this forum sutff that I am still figuring out how it works.)
Thax: I can’t wait till the end to deinterlace because I am slowing them WAY down and have to see the effect while I work to see if I like it or not. It is helpful to know that once they are deinterlaced the will look jaggie when played at full speed. Is that because I will get the flicker that dividing the frame into two fields corrects? I imagine that what the deinterlace filter does is scans the lines sequentially instead of all odd then all even lines. Is that correct? Thanks.

Thanks Mech. I have this question: When I drag the clips back into the browser after I copy the filter onto all of them, can I drag them back individually (which would be my preference) or grouped together in a single sequence. A single QT movie of all the clips will not be easy to work with, but there is a master/subordinate type of clip thing that was introduced with FC4 that I never fully understood. Maybe that would be a way to break them up into apparently separate clips. Perhaps more to follow on this.

John, Thanks. I am interested. But help me out here, is Compressor a codec, an application, a plug in?
