Hi, everyone!

I haven't checked in for a while, but I'm refreshing my website, using PD11 again, and here I am with questions!

I want to create a slide show and one of the features I want to use is dynamically changing chromacity from gray-tones to color. I thought I had figured out how to change the chromacity of an image from color to gray-tones, but I'm not so sure, now. I know I an import a gray-tone version of the original image, but is there a way to do this 'in-house'?

It's occurred to me that I can start with a gray-tone image, and fade in (using opacity) an overlaid color image, but I can't really figure out how to overlay one image over another in a dynamic video context. I know this is possible, since this is how green-screen overlaying works.

Can anyone offer me some tips here? or point out which features I'm overlooking?

Thanks.

Can you not simply keyframe the saturation? Regards,

I experimented and found it is possible to keyframe the saturation. No need for multiple clips on different tracks. I use PD9 but I imagine this will still work in PD11: Position the cursor at the start of the clip and click the Keyframe button. Select and expand the Fix/Enhance option from the Keyframe Settings (by clicking on the small arrow). Scroll down to find Saturation and set the slider to zero. Now in the right-hand pane move the cursor to where you want the transition to colour to begin. Set the saturation slider to zero and click the little diamond in the saturation section. Clicking this diamond sets a keyframe which can be subsequently moved or deleted if required. You can see and edit the keyframes in the right-hand pane against the saturation section. Now position the cursor to where you want the transition to end, set the slider to the level of saturation you want and click the diamond again. Move to the end of the clip and set the slider to the same position again. Job done.

Wow... you nailed it, Fenman. Thanks for the instruction, and thanks for the introduction to the keyframe mode.

Mostly, thanks for taking the time to answer my query.
