Smooth transition between two clips with different clip speeds

  • Question
  • Updated 1 year ago
Camtasia v9.1 Windows. Three sequential, adjacent clips with highly varied clip speeds produce a jarring, instant transition. First clip at 250%, second at 50%, third at 250%. Is there any transition effect which (when applied separately at each end of the middle clip) (a) slows down the first clip at its end point to 100%, then (b) slows the second clip down to 50% from its starting point, then (c) reverses the process for transition to the third clip. Each within user-settable time intervals on each side of the clip seams. For jury presentation, have to make things as "seamless" as possilble. TIA

Hello,
That sounds like a tall order in terms of making the clip speed dynamic instead of constant velocity, or creating such parameters for the transition itself. Maybe somebody chimes in with a trick I’m not aware of.

If I had to get this done right now, I would render the 250% clips as separate AVI (no loss) clips and then reintroduce them into this project timeline. They would move at 250% rate but be seen as “100%” as that is how they were rendered.

"There's ALWAYS a work around". Hmmm.  In an assembly of these three AVI-sourced clips, the system would see each as 100%, but for the viewer the visual transition between clips would still be BANG! I'm hoping to avoid loss of image continuity, but I may just have to insert a visual transition effect between clips for now. I know you guys want to do it! A little bit of calculus and you're there! Always grateful, Bruce.

Just a user like yourself. :)

I did miss one step in the recipe; do the same with the 50% clip. Render it as an AVI sub clip and bring it back into the project timeline and this will also be seen as 100%. Heat and serve.

could you explain what outcome you're looking based on your request?

I made a test project based on your description, applied a simple fade transition [2 sec duration] where the clips adjoined, played the project; but could not figure out what benefit would be achieved with your suggestions

in my example, the clips were all narrated; but narration gets mangled with clip speed adjustments anyway; otherwise, I did not see the point?

please advise further ...

What I'm doing is producing a video for a jury trial, showing the prelude to a Incident captured by a surveillance camera. Clip #1 at 250% provides a contextual overview for jurors, setting the stage. Clip #2 is a slow-motion display of the Incident which allows jurors to see all the individual "pieces" of the disaster (and for the lawyers to shout knowledgeably at each other. ) Clip #3 at 250% skims through the aftermath while everyone regains their bearings.

My goal is to make the speed transitions between clips as smooth as possible, without losing ANY continuity of the original visual image which is, face it, evidence. Per your example Kayakman, I quickly introduced a two-second fade transition between clips, and that may work for now. Timbre4, you've given me an idea which I'll test over the weekend. Many thanks to both of you! Bruce

What you really need is time remapping. Camtasia doesn't have advanced features.

If you want me produce a video for you that's more presentable than overlapping transitions you can contact me at freedommoon1@gmail.com

Thank you, Joe. I'll keep that in mind ... may need it. Re: photo. I'm an incandescent guy, myself, but definitely not the brightest bulb in the pack. Bruce
