Aliasing and V1U

[Chris Borjis]

I don’t think its possible to capture it wrong over firewire.
normally if the easy setup doesn’t match the format, it won’t
capture anything.

Sounds like you shot 24p not 24p advanced which is a good thing.

It also sounds like your easy setup or viewer is not setup
and thats where your aliasing is coming from.

open one of your captured clips in quicktime. how does it look?
I bet it looks just fine.

There really isn’t any point in capturing with apple intermediate codec.
that was a workaround before fcp actually had solid hdv support built in.

Chris,

I went back and looked at my footage clips in QuickTime again, just to make sure I was right, but the artifacts are still there. It looks like a combination of interlacing and aliasing.

I definitely shot in 24p, NOT 24pA. No question there.

When I click through the frames, I end up with three frames that look good like this: https://farm4.static.flickr.com/3049/2947685254_bf6cdf5085_o.jpg

And two that look like this: https://farm4.static.flickr.com/3208/2947684240_4b330318ff_o.jpg

When I look at everything edited in FCS, it looks absolutely horrible. I tried multiple sequence settings, and I can’t seem to find anything that looks right.

Ideas? What have I done wrong somewhere along the way?

Thanks,
Katie

3 frames of good, 2 of bad = 3:2 pullup/pulldown

That would seem to be 24pA footage.

I wonder if the V1U was the problem. (recording 24p in 24pA)

Do you have After effects?

if so, you might bring in a clip of a few seconds and in
the interpret footage area, tell it to guess the pulldown,
then render it out.

that might fix it.

I’ve gone over this issue again and again in the last few days, and can’t seem to solve it.

When put in the timeline, the 3:2 pulldown is removed properly, but the footage still looks like crap. Even the raw footage is low quality and looks like it has aliasing and pixelation when I look at the clips in QT.

Can anyone help me?

If someone can tell me what the best capture settings and workflows have been for them, maybe I can figure out where it is that I went wrong.

hey katie,

is the raw footage OK – if you plug it into a TV monitor direct from camera and view is it all fine? or is it only when it is in Final Cut Pro that these artifacts appear?

[Katie Mims]

Plugged in to an HD TV, the footage looks great. It’s only in Final Cut that the problems occur. The captured footage played in QT looks a little better than it does running through FCP, but not much.

Scratch what I just said. I just looked at more clips on an HD TV, and not all of them look good. Some of them look exactly like this:

So obviously I had a setting wrong when I was recording. Gain? What?

I’ve already realized that I should have shot this entire project in 30p, because there is so much motion going on. Is that related to this poor quality I’m getting?
