Video Speed Adjustments

[jkb]

Not sure if I am doing something wrong or it is just the way it works.

I am trying to adjust the speed of a video so that it is static during the fade in & fade out of the Slide.

I put a keypoint at 0 (start of Slide) & set the Speed to 0 
I have another keypoint at 2 (end of Fade in) also at 0 Speed
I then add another keypoint at 3 sec & set Speed to 70%

This works fine at the start of the Slide.

However the green track does not increase in length, so trying to position another keypoint at 7.6 Secs (start of fade out) Also for 70% & then a final keypoint at 9.6 Secs for 0% Speed I can't
The original video was only 8 secs so I cannot select 9.6 secs

Should the Green track expand to the new adjusted length or am I missing something?

The Overall Duration shows as 15 secs but the green Track still shows the original duration of 8 secs.

 

Also it would help if the actual window was wider as when the cursor is at the end then the displayed time & Speed are off the window & can't be read.

 

I will keep playing until I get the keypoints as I want, but it is a bit trial & error. Otherwise it works great

PS It would be really helpful if it is possible to show the Transition points as in O&A.

At the moment I keep having to make a note of the times & keep coming in & out of the Speed window to try to get it right.

PPS.

In fact the keypoints at the end of the video don't seem to be working at all.

It doesn't matter where I position it, the video isn't slowing down at the end.
The starting points work great, but the end doesn't

Hi Jill,

Please check the About window. Do you use the newest Beta 8? 

In Beta 7 and 8 we added many changes and improvements into video speed editor.

I'll write a mini tutorial for this editor soon.

Hi Igor, yes I am using beta 8.

I just downloaded and installed as a separate version. I will try later to see what it does in beta 7.

I am trying to finish an AV for a competition and the closing date is Tuesday. 

It works ok for now as it is, so no rush if there is a bug.

Jill, thanks, we'll fix it in Beta 9 soon.

Jill, 

The green timeline (with key points) always shows the original time. Including vertical red time cursor.

Mini player placed above (and its time slider) shows modified resulting time.

Please wait a little, I've noticed several issues with time calculations. We'll fix these mistakes in Beta 9. I suggest to try again this editor in future Beta 9.

I am also confused about what can be done with video clips.  In my case I had 4 or 5 clips that I ended up merging into a single clip using Movavi.  Now I put that resulting clip as a slide in a PTEAV show I am creating and it works fine--no problem.  But after-the-fact I realized it would be nice for me to slow down a particular few second portion of that video.  In Objects and Animation I open the Properties and see the Video section and a button for Trim and Adjust Speed which I click. The I see some checkboxes one of which is "speed keyframes" which sounds like something I am looking for.  But I can't find a way to actually add any keyframes in the overall clip.  What am I missing??

You just click in the Green bar & add keyframes just as you do when editing sound.
Click & then drag it up or down
