  • (New) Velocity Envelope Questions

    Posted by Colton Casados-medve on August 10, 2009 at 1:11 am

    Alright, here is my deal.

    I’m filming footage from a game I play. I’m filming the entire session to show that I’m not dying after every kill.

    I want to use velocity envelope to “fast-forward” the parts of me running around finding someone, and then have it slow down the instant I start shooting/killing something. So I did the following steps:

    1. Added a velocity envelope to the clip.
    2. Added two dots after killing someone.
    3. Added two dots just before killing another person after about 35 seconds of boring stuff no one wants to see.
    4. Dragged the line of the clip portion up to make it roughly 200% faster.
    Apologies for that first post. I accidentally posted activation key to forums from copy paste instead of this message, which I had typed before registering.

    This is what happened. We’ll call Guy A the first guy I killed and Guy B the second guy I killed.

    1. I killed Guy A.
    2. Things are going faster, 200% faster roughly.
    3. However, midway between the 4 points I made, I see me killing Guy B.
    4. I revert velocity back to normal velocity.
    5. It shows me killing Guy B when it is supposed to.
    6. I speed it up 200% again. Guy B shows up when he is not supposed to in my clip.
    7. I skip to the end of the clip and notice that killing Guy A and part of the boring stuff afterward has been “tacked on” to the clip.
    8. Revert it back to normal and its all normal.

    The clip events are set to looping by default.
    To disable looping, right-click on the event and toggle Switches / Loop

    This way, the `Guy A` and the `running parts` will not appear again at the end of the clip.

    What about seeing events before htey appear in the clip?

    For example:

    1. I speed up the time in which I do nothing after killing Guy A until I’m right about to kill guy B. But me killing guy B shows up halfway inbetweent he time i’m speeding up and is part of the “sped up” thing. Will your solution fix it as well?

    Btw thanks for being the only reply.

    No that won’t fix that. I assumed you knew that the frames shift when you modify velocity without any change in event size.

    I don’t know how to desribe it but I’ll try;

    This is the clip; (1 means normal speed)
    [1111111 A 1111111111111111 B 1111111111111111111111]

    This is the modified clip; (2 means %200 speed)
    [1111111 A 12222221 B 1111111111111111*1111111 A 111]

    * is the loop point.
    Notice the clip event size on timeline don’t change as you speed up the event.

    When you speed up the clip after point A, the point B is no longer at the same place in timeline. It’s shifted to the left.
    Every change in the velocity shifts the position of the tailing frames in the timeline so you should start editing from the begining of the clip and move towards the end one by one. You need to adjust it precisely so point B doesn’t shift too much and move into the %200 area.
