how can u mend a broken.....file? bad interlace issues
on Nov 12, 2010 at 3:31:35 pm

Hello again

I am working with some files my client supplied, and they show artifacts from not being de-interlaced properly, specifically a "wavy" effect over the image during tilts.
Research shows that the files were de-interlaced but not resized.

The originals are gone, so all i have are the files i was given

HDV 1440 x 1080, 60i,

Is there any way to fix them? I have tried mutiple filters to re- and de-interlace and so on, and it all seems to come out the same.

I can probably do some "strobing" to minimize it, but its an industrial so the effect may not seem appropriate for the context!

thanx in advance! Luv the COW!

Well, maybe not...

The acquisition media -- tape, cards, whatever -- may be gone, but could the video files still exist in an NLE somewhere, with no deinterlacing applied, which you could acquire?

If the answer's no, you're probably hamstrung in your ability to fix the video you've been given, and the client may just have to live with it.

That's a relief. Y'know, this could be a selling point for you: "This wouldn't have happened if..."

As for your subject line, I felt the Bee Gees were much better once they abandoned the front lines of The Great Disco Music Scare of the late '70's and early '80's. Lord, that garbage almost caught on.

I don't get it.
Files were deinterlaced, yet you desribe them as 60i.
Also, why artifacts during tilts?
Bad deinterlacing shows artifacts in pans more than in tilts.

Resizing has nothing to do with de-interlacing.
(although vertical resizing as if the files were progressive BEFORE interlacing causes major trouble)

So start over, what do you have got, and what is your timeline set up like?

Is the problem you're describing what some folks call the Jello-cam effect? Or is it in shots that are static as well as in motion?

thanx

Its the jello cam effect, its on tilts as well as when there is some movement in the frame, X or Y.

(reminds me of Waynes World dream sequence. "Dududududu dudududu")

Bouke

thanx for responding!

Sorry about any confusion. To summarize more concisely, the files are exhibiting the artifacts before i even get them into final cut. The problem lies with the way the files were converted from camera original media, in this case SxS cards, to HDV 60i.

Resizing has nothing to do with de-interlacing.
(although vertical resizing as if the files were progressive BEFORE interlacing causes major trouble)


Yes I believe that is what happened! I was assuming it was de-interlacing. (I should have merely said conversion, as I do not know how the originals were shot. My bad!)
