Hi this is my first post-

Here is the situation

I have a 3 minute clip

the last half is green screened which seems to work

About half way through the clip I needed to add a garbage mat square to the left hand side to cover up an error

How the heck do I make this garbage mat appear at 2 minutes and 20 seconds and end at 2 minutes and 54 seconds.

I have been going through the video help, but they are not helping- I wish that the usermanual was complete with step by step instructions - It is a low priced program and as a result I would assume this attracts newbie video editors is what I am asking even possible

I need the garbage mat to begin 1/2 way through the clip and end just before the ending of the clip

There are two options here.

You can apply the matte shape to the entire object, and then keyframe it so that it is only visible and active during the period you want. So at the start and end of that period, simply move the shape off the canvas.

Alternatively, and probably more neatly, you can cut the clip on the timeline so that the area requiring the garbage matte exists on its own layer. You can then apply the garbage matte to it without it affecting the layers either side.

Check out the interface tutorials here:

http://fxhome.com/support/lab-tutorials

They explain how the timeline and keyframing works.

To do what I described you need to place an additional keyframe with the shape moved off the canvas, just before the first keyframe in which you want it to affect the layer. Do the same at the end, but with the additional keyframe after the final keyframe.

Yes Thanks

I have been through those video's

which one am I to look at because I am not going to go through them all again

sorry to be negative I am just getting sick of weeding through forums and looking at every single video- but it comes across too advanced-

Please let me know which video to re watch- because I have no idea

The timeline and animation ones will be the most useful.

Dude, try this.

1. Scroll to the first frame where you want your mask to be applied.
2. Draw your mask. This will add a key frame to the timeline.
3. Go to the frame directly to the "left" of the frame where you
just drew the mask, select and move the mask off the canvas.
This will create another key frame.
4. Scroll to the frame where you no longer need your mask, then
scroll one frame to the left. select your draw or pencil tool to
draw a key frame on that specific frame for the mask.
5. Scroll one frame to the right, select your mask and move it off
canvas. This will create another key frame.

Alternately... you can have your key frames further apart and you'll notice that your mask will animate itself into position according to how far apart "in frames" the key frames are.

well it looks like it worked

I'll be rendering now for the next 20 odd minutes but it looks like it worked- thank you

Reminds me of using an old swish max flash product by putting stops here and there and moving things off frame

anyway

Thank you
