I’d also add a quick RTFM for Twixtor too. Starting with the fields and see if that solves it.

All the best,

You’ve got a few choices here.

1) Cut up adjustment layers as you were planning to do.
2) Render out two copies of the sequence, one with each colour grade and recut them in your editor – where it’s probably faster.
3) Create two Animation presets – one for each of your grades. Highlight the layers you want to be one style and apply the preset to them, then highlight the other set.

There are other ways to do it, of course, but the quickest would be to use the animation preset method.

Good luck with your project,
Ben

Hi,

You could draw and animate a mask shape by keyframing its path. Or keep it simple and use one of the Transition group of effects. A linear wipe or radial wipe would be best.

That should get you started.

Cheers,

Here you go. Adjust frequency as you want, and the amplitude is your slider.

Just keyframe the slider back to 0 and you’re done.

freq=1;
amplitude=effect("Slider Control")("Slider");
a=wiggle(freq,amplitude);
[value[0],value[1],a[2]]

Cheers,
Ben

[Barend Onneweer] “If your camera is moving you may want to make sure you’ve got something to track. 4 small dots in the corners of the screen will do.”

If you’ve got Mocha then you might not even need the tracking markers. If you do use markers make sure they’re going to be simple to remove, especially if you’re using a blend mode to keep the reflections.

Cheers,
Ben

You could add a Slider Control effect and keyframe that from 100 to 0. Just tweak your expression to:

segMin = .3; //minimum segment duration
segMax = .3; //maximum segment duration
minVal = -5*effect("Slider Control")("Slider");
maxVal = 2*effect("Slider Control")("Slider");

end = 0;
j = 0;
while ( time >= end){
j += 1;
seedRandom(j,true);
start = end;
end += random(segMin,segMax);
}
endVal = random(minVal,maxVal);
seedRandom(j-1,true);
dummy=random(); //this is a throw-away value
startVal = random(minVal,maxVal);
x = position[0];
ease(time,start,end,[x,startVal],[x,endVal])

That will give you the control you want.

Cheers,
Ben

Key your footage with a luma key. Have only that keyed layer in the comp.

Export to a Quicktime file with the Animation codec with a RGB+Alpha. Set your Alpha to Straight. That’s it.

You’d want to track the back hills. Tracking the haystacks would give you a very different set of data, which you wouldn’t be able to use to matchmove the background elements.

If you are tracking an object that is not co-planar to what you want to track then it won’t look right. For example, if you have a sign in the foreground and one in the background, then motion of those two object is different. See Parallax.

Track something that is co-planar to the what you need to matchmove.

All the best,

For a start, you’ll probably be better served using the Render Queue instead of the Export.

H264 is a very lossy codec especially at “web export” standards, which is why you get the small file sizes. The banding is an artefact of data being discarded whilst compressing the video, so one technique would be to give it more data to work with. Up the data rate.

This on its own might not be enough to get rid of the banding, so adding a small amount of noise is a simple technique to help break it up a bit.

You may not be able to avoid completely depending on your subject matter and target data rate.

All the best,
Ben
