Velocity Envelope

Opampman wrote on 4/2/2010, 7:03 PM

I have some old Super 8mm footage that, I believe, was shot at 16 fps and transferred to VHS at 18 fps. I want to slow it down to 88% using a velocity envelope. What I have always done before was right click on the track, select velocity envelope, and adjust the line down to the speed I want. I tried this in VP9 and nothing happened. I did not get the velocity line. So, I went back to VP8 and it worked exactly as it always has. Anyone know what I'm doing wrong? This is exactly what the VP9 HELP file says I should do, but it doesn't work in 9 but it does in 8.

This is strange. I have no problem with velocity envelopes in V9. I can't think of a way to turn this feature off? Should work in V9 as in V8. ..

There is another way to get a velocity envelope.

Select the event(s) on the timeline.
Click Insert / Video Envelopes / Event Velocity

This is strange. In fact, the first way I tried to do the velocity envelope was your second method - INSERT - VELOCITY ENVELOPE - still no go. That's when I read the HELP file and it said right click...yada yada yada

Found it.
There is a setting to "turn off" the velocity envelopes.

Click OPTIONS.
Hold down the shift key.
Click Preferences
Click Internal (upper right tab)
In the search box at the bottom, enter "show event envelopes"
Click in the "Value" field (at the top) and enter TRUE.
Click Apply (at the bottom)
Click OK.
Should work.

Well - thanks for that find. Unfortunately it is set to TRUE by default so that wasn't the problem. I just tried it again this AM and still cannot get a velocity envelope on the track. I emailed Sony so maybe I'll hear from them next week. In the meantime, I'll just work in V8. Thanks again.

This intrigued me so I went further and learned something and was able to reproduce the state your V9 must be in... I think ...

First, you can turn "show envelopes" on and off in the View menu or toggle it with Shift-Ctrl-E. But that was not the problem.

Second, there is another setting in the View Menu under Video Envelopes that allows you to turn on and off many different types of track and event envelopes individually including Event Velocity.
So --
Click View / Video Envelopes / Event Velocity.
Make sure Event Velocity is checked.

WOW - how did you find that? I hope I don't have to pay you by the hour for all that work - but that was it. I've never been into that menu so I wonder how it was unchecked. Anyway - that fixed it! Thanks a million!

Hey Robert. Just giving back to this fabulous forum for all the stuff I've learned here and am still learning. I'm far from an expert ---

What is strange is that I can't find this setting in the Internal settings? Has to be somewhere to toggle on and off like that --- maybe the registry?

Paul,

Nice work and a perfect example to the usefulness of this forum.
