stabilizing NTSC footage (how to deal with fields)

[Andrew Kramer]

Usually you want to deinterlace then apply stabilization. but you may want to use the tracker on the original footage not the deinterlacced stuff.
so technically, stabilize then deinterlace but you must deinterlace the source, not the stabilized footage.

Not that this makes any sense…

Hi Andrew, thanks for your response. That seems to makes sense to me.
Once I have stabilized the deinterlaced footage do I need to then somehow reinterlace it or will the deinterlaced stabilized footage look OK on TV. Also, do you recommend a certain plugin for deinterlacing. Or do you usually do it yourself (I think I saw a tutorial by you about that, right?)

Thanks
Pete

I use fieldskit by RevisionFX.

I’m not sure how you might easily re-interlacethe footage. But the deinterlace tutorial would give you an idea. It can be done but i’m not sure how much better it would be.

but if you dare…
go to videocopilot.net and download the project file and source footage and take the scanlines psd and use as a matte.

1. stabilize an deinterlace a comp with odd fields then stabilize and deinterlace a comp with even fields.
2. put both comps onto a new comp, use the scanlines.psd to set the track matte to the luma matte for one comp and use another instance of the scanlines for the other comp.

I’m not sure which would be first but you would want the lower fields first to have an empty pixel at the top line and the upper fields comp empty bottom row. check out the tutorial and play around it may sound complicated but will work right… I think.

I wasn’t aware you needed to mess with the interlacing to do stabilization… When I stabilized some MiniDV NTSC footage, I didn’t do anything but stabilize… and it was fine.
