I just wanted to add that the DVD specs call for VOB’s no larger than 1GB. Anything larger gets split up. There must be a good reason for the 1GB limit for a single file. And those folks certainly know their stuff.

Even if your is a data DVD, I’d still adhere to what the experts limit. Share this with your client.

a single 6GB is ridiculous. This sounds like a file corruption. I’d try copying the disc using another machine. Repeat and rinse. If the results are identical then get back to your client to tell them that the file is corrupted. Let them know that they should split the file up during the render stage into pieces no larger than 1GB.

This is one of those things real-world lessons that are painful to learn.

Good Luck

Hi Eric
Are you using any proxies? Why not list down te Render and Output settings. As mentioned earlier, I’ve got a hunch that something there is causing the problem cos’ it explains why the RAM preview works and a render out doesn’t.

Hi Eric

Thanks for coming back with the answers. I would try to render a short segment into an Image Sequence and see if the results are identical. My hunch is they will be as I have a strong feeling that it’s PAR related. Take a look at your Render and more so, your Output settings, including QT settings.

I suggest that you send a report to Adobe for them to have a look-see into this if things still don’t add up on your side.

Depending on the trajectory of the particles, youmay be able to get by without roto-ing the bike. IMO, it’ll still look ok if the particles were in front of the bike throughout the entire duration. As long as the particle stream makes it around the buys head, you would have sold the 3D-ish look to the viewer.

CCSphere wraps things around a sphere and other than rendering the entire sphere, it allows you render either just the front or the back of the sphere. So, in my case, after roto-ing my subject out. I placed them in between each instance of the front-only and a back-only instance of the sphere, which contained a flight of particles.

Kinda hard to visualize it. But once you’ve messed about with CCSphere, you’ll have a better idea.

[zygotesoup] “So, if I’m understanding this correctly… the difference matte compairs the 2 pieces of footage and creates a matte in the shape of the objects that are different??? I think I’m gonna have to play around with it to really understand what it does.”

YEP! The AE manual covers this with a simple pictorial example. Check the Help->Effects menu item and there should also be a similar example.

Why o why did you install Vista??? It sounds like an early adopter problem. I’d try to test the AEP on an XP machine just to make sure.

Good Luck

Stop using Tint and see if that helps. You can replace Tint with Effects->Generate Fill. If you have the Cycore plugins installed, then you’d want to look at CC Toner, which does a better job.

A Difference Matte is created by looking at TWO footage items and ten creating a matte of the difference between them. Say, you’ve got a footage of a wall. To make things simpler, let’s assume that there’s no camera movement of any sort. On another shot, same camera, same everything; you’ve got a car entering your shot and stopping.

So, now you’ve got two shots
1) wall and nothing else
2) wall with car entering screen are

You would then apply a Difference matte to either layer (doesn’t matter). Within the Difference Matte’s Effects Control pane, you’ll find a parameter for selecting the second layer from which to pull out a matte. So, you may want to apply Difference Matte to the wall layer and then select the second shot with the car.

The trick is to find a backplate that is as consistent as possible – lighting issues, no movement from elements, watch out for shadow/sun movement, trees/leaves, people etc. Once you find a backplate that allows for the most control, you’re about half the way there.

The next bit involves knowing how to massage your matte once you’ve apploed Difference Matte. Lots of techniques here and you may actually be using more than one, including masking.

First off, you’re rotoscoping isn’t as difficult as you may think. You’ll only need to rotoscope for the short segment where the particles move behind your talent. That’s no more thab 3 seconds and it only covers part of the head region. The talent is pretty static and that’s going to make things easier.

I once did a whole bunch of these type effects using multiple instances of CC Sphere.

I believe that Particular has a Z-position for the emitter. Once you’ve cut out your talent. Place a copy of the original footage on a seprate layer. Only the roto-ed layer needs to be made a 3D layer. Then just animated the position of the emitter so that it goes around the talent at the required time.

For this, just start out with x and y positions for the emitter. Once that’s fine, set the z-position accordingly.
