Reverse velocity

Cooldraft wrote on 7/13/2003, 9:15 PM
Is there a way to just reverse a clip? I know that you can do 100% reverse velocity it will play in reverse, but if you have a 10 second clip that starts at 00:40:28:02 and ends at 00:40:38:00 of the raw footage and do reverse velocityin the timeline the event start time moves so I have to scrub to find the exact place I want and it is hard to scrub with the mouse to the exact place. For example copy three 5 sec clips in the timeline. The goal is to create the middle clip 100% reverse that match clips 1 & 3. How is this done easily?

You do it exacly as your subject line says:

1. Add a Velocity Envelope to the clip
2. Change the velocity to -100%

TIP: Start at the END

Could you please explain what you mean by this?

I think I know what is ment...and I have the same questin...I had the same problem trying to reverse the velocity I would shorten a clip of raw footage that was extra long, then slice it into lets say 3 parts... you want the middle one to be reversed so it matches with 1 and 3. but when you drag the velocity to -100 it goes back to the begining or end of the complete raw footage and is very hard to find the section where you wanted to reverse

I believe this is what you were explaining... if it isn't sorry for the confusion, but I would also like to know an easy way to do this

thanks for your time

Edward means if you want to go backwards, start at the end, because you'll end at the beginning. I you move your middle clip to a lower track, it may be easier to see what's happening. Enable snap to, and it's a piece of cake. Drag the clip so that the first frame you want to see (the end of the clip) is at the beginning (where you want to see it). Pull the edge of the clip so it fills the gap. Set the velocity for the clip to -100%.
You don't need an extra track for this, but it makes it easier to grasp.

Yes, I know you can scrub using alt to get it to the correct frame, but this is hard to get perfect, if not impossible. Jump. You are exactly right. I don't see any easy way to do this automatically. Maybe Excalibur would help?

I see.

I noticed when I would use a -100 envelope, it "just didn't go right." I did not see what I thought I would see.

What I did was render the exact clip/event I wanted to a seperate, stand-alone clip, then reverse that clip to and fro and all worked perfectly. It would seamlessly integrate with my main video seeing I had it down to the exact frame.

Hey, that *is* one way... :)

Thank you all for my answer.

If you use separate tracks and enable Snap (press F8 to toggle) you will have no trouble at all finding the exact spot. (We are talking about separate events here, events that come from different footage or are split from each other - because if we are not, it's a slightly different story.)
And if you expand track layers (small icon left of Levels at track head) it is just as simple. (Snap won't change things here.)
In both cases the idea is, when you've set the velocity to -100%:
1 Drag the middle event to the left until its right edge aligns with the right edge of the previous event.
2 Pull the right edge of the middle event until it aligns with the left edge of the third event.
(If you are on two tracks, you're done now, if you've expanded the track):
3 Pull the left edge of the middle track until it aligns with the right edge of the first.
Even Dad could do it.

EDIT: Please note that when I say Drag, I mean move the event and when I say Pull the edge I mean expand it.

Thanks, Grazie. And thanks for reminding me about the Expand track thing, which you did on another post I read this morning.

Due to popular demand (or maybe because it's housecleaning day today) I'll follow up a little:
If it were one event you wanted to manipulate, don't do the mistake I did until recently. Don't split it (Thanks, Ed).
Insert Velocity envelope. With your cursor find the point from where the action should reverse (the last frame of normal view). Add point there. Now find the point where the action gets normal again (the first frame of normal after the revese. Add point there, too. Make two more points, between the first two, one close to each of them. Now pull down the velocity envelope, it will only go as far as -100%. For smoothness or abrupt change, pull the middle points to either side.
