matte question

I have a basic question, when using a stock photo for a plate the industry standard seems to be 4k. my question is would this pertain to the horiz res, 4k after resizing in photoshop…. I have searched for this answer….I believe it is corresponding to the original photo but not sure…

thanks in advance, Bruce

Making a character unrecognisable

Nick takes us through 3 different ways to render a character unidentifiable in an interview situation.

WITNESS PROTECTION

In the first instance, he uses an image mask in Final Cut Pro to colour correct the image and applies a pitch shift to change the voice.

In the second instance he uses a blur filter and an 8-point garbage matte to blur out the characters voice. He then shows you how to use the ‘paste attributes’ setting in Final Cut Pro to apply an audio effect created on a previous clip to this new clip.

Finally, he uses After Effects to motion track a number of black bars across the distinguishing features of his witness under protection.

Fusion 6 or Latest Nuke?

Many say Nuke is the ultimate winner…Been using Fusion 5.1.When Nuke 5.2 hit the market they all said me "go for Nuke..go for Nuke!".Then Fusion 6 appeared and it all became blurry again…Can you please enlight?I didn’t have the time to go through the site for answers…Please..would it worth to go for Nuke instead of moving to Fusion 6?You don’t need to go into extreme specifics…I already know that Nuke doesn’t have particles.What about non destructive paint functions that already work beautifully with Fusion and not so much with Nuke?

Thanks again.I keep growing!

Need Help with a Matchmove

Hey team,
Well i’ve always thought matchmoving moving looked rather easy but after 2 days of hell i take it all back!
I’m trying to track a dolly shot (with PFtrack), there’s no pan, just a dolly in along flat ground. As far as i can tell, PFtrack thinks that there is some movement along the Y axis. There shouldn’t be, and if there is, it is very minor.
i’ve uploaded a low res version of the shot. and a preview from PFtrack. Everytime i have a go with PFtrack i get different results but always the Y translation which i know isn’t there so i feel like if i can get rid of that then i should be able to sort it.
The example from PFtrack has Mushroom and a cows head in it to show how poor the track is. It’s OK (actually pretty bad) at the start with the mushroom but it get worse with cows head. My aim is place some CGI on the wooden board at the end of the shot.
It’s actually quite important that i learn how to track this shot so any help you can give me will be greatly appreciated!

Making a Fake Lighting Rig

Nick takes us through the steps of creating a fake lighting rig in After Effects to composite behind rocking out guitarists. He uses Knoll Light Factory to produce the lights which you can download via their website.

Rock Lighting

This is a cool tip for anyone wanting to make background elements for their music videos etc.

Rotoscoping hair/fur

Hi everyone. This question has always been in the back of my mind. How do you rotoscope hair or fur? To me it seems pretty impossible with all the itty pieces sticking out and splines generally give a curve shape to everything. There’s always leaving out the details but it will look fake. What do you guys do when it comes to this?

dual monitors….

hey everyone, newbie question 😀

I have been seeing some people using more than one monitor, i was wondering well… WHY? lol
Thanks i appreciate it!

3D matchmove geometry creation

I have trouble understanding how to generate 3D Geometry from a shot/image for compositing. See these examples:

rtep demo reel

and Donald Strubler’s reel

I am trying to recreate this for some shots I have, yet I can only get one example to work. I took the 101 and 201 course of syntheyes on fxphd, so I know how to track a shot and generate a point cloud.

What I don’t understand is how to generate the 3D Geometry and make it fit so perfectly on the shot.
There is a software called ImageModeler:

http://www.youtube.com/watch?v=VdA0m_sou-g
It does the task really well, but that will only work if you have lots of photos from different angles of the shot. I only have the shots and the frames from the camera move, with one being a nodal pan without any paralax. The buildings I want to generate geometry of are moving out of frame.

Also how do you generate a perfect match with only one photo? There is a match option in ImageModeler but that didn’t work for my shot at all. Eyeballing it in a 3D application can’t be the only way to do it, it takes just too much time.
