AHHHHHHHHH!!!!!!! Ok, so I got an idea after watching Disney's version of Herculese with my little cousin. I saw how Hades made things appear and I thought, " I know just how to do that!" Easy rite? Make the Bamf! black and do a little masking. WRONG!!!!!!!! The effect won't appear! I see the emitter and everything! I even set the color to white on a black canvas! I looked at every single frame. It just wont appear! Help anyone? Greatly apreaciated. crazy

You are referring to the Bamf! v1 preset, it sounds like? As opposed to the stock footage versions?

It won't appear over a black background, as the Blend mode is set to Multiply. Put some footage behind it, and the effect will show up. Otherwise, change the blend mode to something that shows up over black, like Add, Screen, Lighten, or Hard Light.

Also, this thought just occured to me. Does anyone know how to do these two things?

1: creat new backgrounds that I can use with a greenscreen. (Like a star destroyer or somethin)

2:Does anyone know what the transparency grader ( if you double click grade then scroll down on the top list you'll see it) is for and how to use it?

I posted these things on this thread so that people could just reply all at once. twisted

Backgrounds are just images or video clips that you import. So there are lots of ways you could create them. You could go out a film some shots to use at various locations. You could build a set, then take a bunch of shots of it that you could stock for future use. You could build a set in miniature, and film that. You could use some models and film them. You could use 3d software to construct and render a 3d model. You could use Photoshop or something similar to combine a bunch of photos into a digital matte painting. You could use actual paints to create a matte painting. You could use digital painting software to create a picture to use as a matte painting.

There are more, of course, but hopefully that list gives you the idea that there are lots and lots, and lots, of ways to go about it.

The transparency filter is very simple and straightforward, and does exactly what you might expect, it adjust the transparency of the layer it is applied to. So if you want a layer to be partly transparent, add a transparency filter and turn it up a bit. If you want it to disappear entirely for a bit, you can use the transparency filter for that as well, just turn it up all the way. You could keyframe it from complete transparent to completely opaque to make someone reappear, for example.

As far as the compositing question, you'll have to provide more info, I'm afraid. How are you compositing 'something'? What compositing technique are you using? What exactly disappears? The thing you are compositing? Everything else?

First off, thanks for all your help! Ok so to give you more info, I'll say that I had a clip on the canvas. Then I tried to make a part of it disappear, but when I clicked "composite" then "transparency" and put it on the canvas (clip) everything on the canvas just went away. I also tried this with distortion but that also made it all disappear.

Everything disappears? So you can't see anything on your canvas at all?

Any time you add a grade filter, you will move into Grade View, which should only show the track you are working on. But if it doesn't show anything at all on the canvas, perhaps you have already adjusted the transparency to make the layer invisible?

Look at the top right of the Canvas, and find the View menu, where it says "View: Grade view - selected track only (no bounds)". If you need to see the other layers while grading, select the project overview instead, from that menu.

ok just figured I'd keep posting on this thread. Does anyone know how to save something. I made an effect that I really liked, but couldn't save it.

OK, at this point I'm going to recommend that you have a look at the video tutorials, as pretty much all of the questions you are raising will be covered there. They are the quickest way to familiarize yourself with the basic workings of the software. Feel free to search the knowledegebase as well; there's lots of useful info there also.

You can save a VisionLab project in the file menu, where the Save commands are located. If you want to save an effect in particular, you have to create a preset, then you can recall that effect to use again any time you need to. You can create a preset by right-clicking the name of the effect on the timeline, and selecting Create Preset from the contextual menu.

If by save you mean you want to export the effect to a movie file that can be viewed in other programs, you need to Render. This is done by opening the Render menu and selecting Render.

Also, its better to keep a thread focused on a single subject, so that any answers provided are easy for others to find later. If someone else has a question regarding layers in the canvas disappearing when they enter Grade view, for example, they are unlikely to look in a thread titled "Bamf! help? The effect won't appear on the canvas!" So titles specifically related to the topic help keep the forums orderly. Thanks!

Hey, sorry about the posting thing, but I'm pretty sure that this has to do with Vision lab, given the fact that it was in the "product example" things. In the examples, people turned invisible. How to I do that? Add a mask then do some distortion? Is there a tutorial somewhere? (I checked the video turoials but couldn't find it.)
