    Gif transperancy & Flash timeline

    Okay well I am planning on messing around with movements in pivot and importing to flash to add backgrounds, vCam and maybe some effects etc. To do this though I need to do sort of a green screen thing where I am able to make all white parts of the animation transparent so I am just left with the stick figures for each frame. Can anyone show me how? I tried this one thing on gimp through a tutorial but it didn't really work out well in the end, the first few frames were all screwed up and importing to flash created a timeline problem.

    My 2nd problem relates back to the flash timeline issue, sometimes when importing gifs to flash it doubles up every frame which isn't a massive deal as I can just double the frame rate. But when I tried importing my dodgy transparent version of a gif I exported from gimp, when I imported it to flash each frame was 128 frames long and flash has fps limit of 120 so clearly I can't remedy it that way. Is there a way to avoid that from happening? Maybe a way to reduce all repeated frames to just single ones like the merge feature in pivot?

    Any help, links, explanations, videos etc. would be much appreciated! Thanks

    I have two ways, but most of the time they don't give very clean results.
    Open the spoiler if you would like to see them (Spoiler to save space).
    [spoiler:2377nmpf]First import the gif you would like to the stage in flash.
    [tn=800:2377nmpf]http://i.imgur.com/myp5j.png[/tn:2377nmpf]
    Then right click on it with the black cursor tool and select break apart.

    Once you have done that your image should have small dots all over it. Select the lasso tool and click the magic wand tool at the bottom.
    [tn=800:2377nmpf]http://i.imgur.com/CeHbn.png[/tn:2377nmpf]
    Then click on the white background you would like to get rid of and press delete, as you can see it doesn't give very clean results.

    Background colour change to see the transparency.

    Another way to do it is to select the stick figure yourself and moving it from the white, this takes a lot longer than the magic wand method.
    Again, import your gif, right click and press break apart.
    [tn=800:2377nmpf]http://i.imgur.com/QOoOq.png[/tn:2377nmpf]
    Select the lasso tool again but instead of pressing the magic wand tool at the bottom, select the polygon tool under it.
    [tn=800:2377nmpf]http://i.imgur.com/6rn30.png[/tn:2377nmpf]
    Then starting wherever you like, click and drag all around your stick figure (not selecting any white backgrounds)
    [tn=800:2377nmpf]http://i.imgur.com/OvVmX.png[/tn:2377nmpf]
    Once you have done that, double click to end it and drag it away from the white background.
    [tn=800:2377nmpf]http://i.imgur.com/cPpCN.png[/tn:2377nmpf]
    Selecting the rest of the white area and getting deleting it is necessary on both methods. Yours should look a lot cleaner than mine because I did mine as a small example in about a minute.[/spoiler:2377nmpf]
    Hope I helped a bit.

    Thanks man I really appreciate that, especially how you went to the extent of screen shotting, I will definitely give it a go. I would assume methods involving something like photoshop or gimp would work better, so if anyone has some methods for using those programs (preferably gimp) I'd love to hear them
