vectors couse blurry s***t

Posted in: Adobe After Effects
Hi guys
i have a very strange problem with vectors, ive render out my sequence from vray ( max) and ive import the whole scene into nuke to discover that i really cant get the vector blur to work, so i make all my stuff into nuke then i render into 32bit exr sequence and i plug the seq into after to apply the blur trouh reel smart motion blur, but for unknown reason, randomly some frames came out blurred like under water, they look very blurrred in the wrong way, then go on with a usual computetion, someone have any clue?
thanks

50% gray in a 32 bit linear project

Posted in: Adobe After Effects
I am trying to understand some basic stuff in terms of the linear work flow. I hope someone will have the answer to enlighten me.

I am having trouble understanding how to interpret 50% gray while working linear, this seems like a fundamental issue to me, but maybe I am wrong? Again enlightenment would be appreciated.

To explain my confusion I have a few images:


This first image is an 8bit render from a 3D application, as interpreted by After Effects in an 8 bit sRGB color space project. As expected 50% gray is visually, as expected, halfway between black and white.


This next image is a 32 bit render from a 3D application. This one is gamma corrected so that it will be interpreted properly by After Effects in 32 bit linear color space.


This last image is the 32 bit rendered image as interpreted by After Effects in a 32 bit linear space project. As you can see the grays are identical visually to the 8 bit image, but the values have changed. Why is this occurring? Is it a good/bad thing? What are the implications for compositing?

Thanks for reading or for answering any of these questions.

Photo Tracking/Compositing Problem! Need some help!

Posted in: Adobe After Effects
Hey guys

I’m trying to track a shot where some guy holds a green piece of paper with some track marks on it. I’m trying to composite a photo on top of that lil mini-greenscreen (unfortunatly it wasnt possible to have the actor look at the real photo so thats why we had to go with this complicated mess). there’s a bit of movement and a bit of paper bending involved. we’ve been trying for ages to track it in mocha but all we get is a really really shaking track. plus I cant seem to find out how to adjust the photo to the bending that happens when the actor holds the green sheet in his hands.

anyone’s got any idea on how to approach that successfully? THANKS ALOT!

cheers!

Faked in-camera slow frame rate

Posted in: Adobe After Effects
Hi all,

I’m trying to recreate the look of shooting 6fps in-camera with each frame printed four times (to get back up to 24fps). It’s used quite heavily by Peter Jackson in LoTR. The key characteristic of doing it in camera are high motion blur in each frame (since it was actually a 1/12 sec exposure).

I have 24fps footage. Applying the “Posterize Time” effect set to 6fps gets the frame rate down; turning on frame blending gives – well – frame blended 6fps material. Finally adding a Timewarp filter with speed set to 100% but motion blur turned on starts to smooth the blended frames.

It’s still not quite right, though. Ideally, I’d be doing a pure motion interpolation from the 24fps down to 6fps – with all those extra frames to hint it, the algorithm should be able to create wonderfully realistic motion blur.

Any thoughts?

Ben

Linear light -> “Video” -> Quicktime – washed out image

Posted in: Adobe After Effects
I’m trying to learn about linear light compositing in After Effects and think I have pretty much understood it, but one thing I still can’t figure out.

I work in a 32bpc Linear sRGB comp with linear Open EXRs. Everything works wonderful. When compositing is done, I want to do color correction. I’ve read that color correction is “best” in video space (gamma corrected) so therefore I make a new comp with my master comp and apply a Color Profile converter to my comp. It becomes very bright and washed out (double gamma I guess), so I turn off the “Display compensation” and I’m back to normal. I do color correction and everything seems to be working – until I export the quicktime master. It is bright and washed out. I have a double gamma somewhere. In the export setting I set sRGB.

Any ideas to this would be very appriciated!

Posted in: Adobe After Effects
Hey All,

We’ve just released two cool new plug-ins for After Effects. We’re really pleased with them, and pretty excited to see what you all come up with using them:

CameraTracker – matchmoving, directly inside of After Effects.
http://www.thefoundry.co.uk/products/cameratracker/

Kronos 5.0 – super fast, gpu accelerated, retiming.
http://www.thefoundry.co.uk/products/kronos/

There’s a training series for CameraTracker, to get you started, over at:
http://www.thefoundry.co.uk/products…cker/training/

And a few examples of what people on the beta put together:

Limit wiggle and keyframe move

Posted in: Adobe After Effects
I am using following expression to wiggle my object on the Y axis:

Quote:

w = wiggle(.5,300);
[value[0], w[1]]

How can i limit the wiggle so that it doesn`t go below and above certain value?

2nd question, I am using VideoCopilot SureTarget with about 30 compositions, is it possible to point keyframe to a slider and then the keyframe moves to a frame which is slider value. And then point the second keyframe to the first.
I would like to have sliders, and control the time when the transition from the target to target is happening.

Thanks for help.

Mixed format workflow within Adobe CS5 Suite for 2k Output

Posted in: Adobe After Effects
I have multiple formats of RED footages in 2k, 4k apart from that DPX files in 2.35 Anamorphic format and DSLR footages too.

We would like to do the full post production within Adobe CS5 Suite. Edit in Premiere, Compositing & Grade in Aftereffects with color finesse.

Our final output would be in 2k DPX sequence Master @ pixel aspect ratio square – 2048X872

My doubts are as follows :
1.) While working we would need to PAN & Zoom in RED 4k files. Is that a good practise to do it in premiere cs5 ?
2.) What are the recommended project setting & Interpret footage settings ?
3.) I have planned to import all the footages as it is to Premiere and assume them as 24 fps using Interpret footage settings. Is this is a good practise to do it in premiere cs5.
4.) Since my output will be 2k, can i modify RED 2k settings to 2048X872 @ 24 fps @ pixel aspect ratio square and continue to edit?

I have already gone through this article
DAVTech Table – Editing with RED 1.7 Technical Overview. It discusses only about RED.

Regards
Siva
