Hdcam bad frame

Hi,

Here is your frame:

I interpreted the footage to lower field then rendered a still.

I hope this helps.

Salut.

Yuck. Here’s one attempt in AE:

1) drag the footage into a same-sized comp.
2) make a comp-sized solid. Drag it down so it covers the bottom half of the footage, where the lines are.
3) apply effect>transition>venetian blinds at completion=50, direction=90, width=2. This should cover every bad line.
4) create a new adjustment layer, and place it below the solid, above the footage.
5) make the solid an alpha matte for the adjustment layer.
6) apply color balance and curves to the adjustment layer until the lines seem to go away. I set shadow blue to -16, mid green to -6 and high red to -7. But I was in a hurry. 🙂 As for the Curves, I pinned down the center point and the one down and to the left (sorry to get technical) then dragged down the curve just a little, just to the right of the black point.

If I had more time, I’d futz more.
You can really only tell during playback.

Or … you could use the solid as an inverse alpha matte for a dupe of the footage, then shift the dupe (and matte) down one pixel, so you duplicate the “good” lines for that one frame. Just another option.

Let us know what works, eh?

Thanks Serge,
This is one thing I didn’t try because the footage is progressive. Can you explain why this works if there are no fields in the footage?

Hi,

Well, looking at your still I thought that the camera must have screwed up with one field. So eliminating this field by deinterlacing would do the trick.

Salut.
