about clips & time offsets

[coccosoids]

and one other thing:
is it possible to pick a custom color from just one frame and then have an operator (like wand) create a mask from a sequence based on just that color extracted automatically from the frames ?

thanks

Ok, you have a lot of questions all wrapped up in there....

1) The easiest way to time offset a number of copied nodes (if I'm understanding you correctly) is to just toss a time speed tool into the connection after all the node tree. In there you can set a time offset (ie to be 10 frame delay, or a -10 frame delay). This will then render all your keyframes etc at the specified delay.

2) If you do this in the timeline, you can ctrl select all your nodes for that group and slide them to the left or right as needed. That being said, the timeline can sometimes be a little quirky.

3) To trim a clip, look in the loader, and set the trim in slider to frame 10 etc. Your keyframes for all following nodes will then need to be offset as well to maintain the relative timing.

4) If you are looking to use a magic wand, there is an effects mask called wand. With this you get a number of settings to adjust how it keys the footage to pull the mask. If your footage is moving, you may need to animate the center of the wand control to follow.

Best of luck...

thanks for your time...

that's exactly what i did, then grouped the nodes together > copy&paste > timeline > crash!!! :) ...

i shall look into that 'time speed tool' as soon as possible
thank you once again

ps: this maybe a little too much already, but how do you play a clip backwards for just a number of frames and then resume it?

whoh, i'm done :)

[Jayk2k]

To play a clip backwards, you would need to use either a timestretcher, or use an IFL file list.

The time stretcher is internal to fusion, and allows the smooth transition of frames. It is essentially just a frame blender, and doesn't do any kind of motion analysis. to use it in your application, you would need to set a keyframe at the head of the shot at frame 0, and a value of 0, then go to the frame you want the clip to start playing backwards, and set the same value as the frame (ie 100,100). Next move to the frame that you want the clip to stop playing backwards, and set the appropriate value (150,50) and then the last frame of the clip (200,100).

An ifl list is just a text file pointing to each of the frames you want to play in the loader, so depending on what you are looking for, this can either be a real time saver or a complete waste of time. ;)

got it ! thank you...
but yet another 'monster' emerges: merge nodes sometimes get a very short timeline range (so we might say activity range) which maybe is extracted from the length of the first clip > this results in the merge operator going 'off' after the length of the first clip is computed trimming the remaining rest of the second... (i'm using time speed on the second clip)
so how can i make it active for a number of additional frames > because editing the timeline manually results in erratic behaviour on the part of fusion...
if help me on this one aswell i really owe you some...
thanks :)

[Jayk2k]

Merges are tied to the background footage length, because it's impossible to merge over something that doesn't exist. To correct it, you can do 2 things, 1) set the background clip to hold it's last frame or loop so that it's there all the time, or 2) merge all your footage over a single black background to maintain the correct resolution and length of your project. Generally the second option is the prefered method.

i can't thank you enough... :thumbsup:
although i'm a bit down as it seems we are the only two fusion users here... :)
cheers

If you are not concerned about complex merging options but only changing clips using a Dissolve Tool instead of a merge could help.

Unlike Merge Dissolve uses any linked Available Footage if one gets out of gloabal range.
This is a simple way to attach some clips in fusion IMO.
