speeding up accordingly

[Alex Gat]

Hi,

This is something I don’t know how to do precisely, I always fiddle around but maybe there is a quick solution for it.

Let’s say I have a 60s long clip. I want to make an edit 30s long with it.
I want to start with a normal speed for the 10 first seconds of the clip and to end with a normal speed with the last 10 seconds of if.

So the middle part will be sped up, but by how much? Is there an easy way to either calculate it (I think I could find the algorithm) or to do it, a function maybe?

Thanks a bunch.

its fairly basic math.

60 second clip – 20 seconds (first and last 10 seconds) = 40 second clip.

How fast does a 40 second clip have to run to fit into a 10 second hole?

I’m guessing around 4x faster than normal.

Hi Alex,

 

Result Time/Original time * 100 = speed percentage

for your case it 10/40*100=25%

 

Hope this solves your problem.

have a good day!

Sorry Mohammed, but your result is confusing.

Are you saying the OP should run his footage at 25 percent speed to have the clip fit into the hole? That isn’t going to work.

Again, its pretty simple “Editor Math” as shown above.
