Using Velocity Envelope, Loosing luminosity
Hello everyone
First time using this feature in Vegas and I am completely at a loss… I am applying the Velocity Envelope to a 45 sec. clip with a white background in increments of 250% each time after render. (I have to narrow it down to 6-7 seconds)
Each time I apply the envelope, I lose about 7% luminosity. Red channel stays the same, green drops a bit and blue even more.
Project is an Sony .MXF file, 50Mbps (CBR), 59.940 fps prog.
I can’t figure it out.
Any suggestions ? Explanation ?
Cheers !

First, which version of Vegas are you using?
Second, are you talking about “velocity”or “composite level”? Why would Velocity (speed) reduce your luminosity?

Hi Paul
I’m using V.14 and Velocity only.
That’s the thing, it shouldn’t affect the luminosity as far as I understand it. There are no other effects applied, not even Event Pan/Crop. All files were shot with the same camera, same controlled lighting, on the same morning, inside.
I’m at a loss…
Cheers !

Three questions.
Are you measuring the loss of luminosity after the render in the rendered file?
How exactly are you measuring the luminosity at about a 7% drop each time?
Can you repeat this behavior with different media and different render settings?

Hi Paul
[Paul Berk] “Are you measuring the loss of luminosity after the render in the rendered file?”
Yes, after I import it back to Vegas
[Paul Berk] “How exactly are you measuring the luminosity at about a 7% drop each time?”
With the Vegas included Waveform (luminance)
[Paul Berk] “Can you repeat this behavior with different media and different render settings?”
I will do some testing and get back to you.
Many thanks for your time !
Cheers !

Hi Paul
Tried it with other rendering formats and could not reproduce the problem. I was hoping to keep all my files in the same format as the original files.
If you ever come up with even something of an explanation, let me know.
Cheers ! …and thank you !
