I've basically created an entire timeline of roughs in various colors and shades, but I'd like to convert it all to a uniform greyscale value. How would I go about this?

FX Stack -- Color -- Black and White Converter . Select All frames and Apply FX Stack.

Thanks! Just what I needed!

A note if you want the grey to be a single value...
Then a better option would be to make use of the "preserve transparency" lock in the timeline.

Because the Black and white converter leaves the luminance value of the original colors intact and would thus result in a range of different greytones.
But if you first lock the alpha channel( with the "preserve transparency" lock in the timeline.)
you can then color all pixels in the exact same shade of grey

use either a rectangle fill:> select all images of the layer (double click under layer) apply rectangle fill over the whole surface of the project, press enter (to repeat fill action over all frames)

or the floodfillt:> select all images of the layer (double click under layer) apply floodfill with range set to 255, press enter (to repeat fill action over all frames)

Another FX Stack option which is very interesting, very powerful: FX-Stack/Stylize/Color Range.

Set it up as shown below with the Luminosity Channel selected. Then make sure the Gradient option (in the "SPECIAL" Gradient Panel** ) is set for APen to BPen.

For starters, set the APen color to black and BPen color to white which will "gray scale" your image.
Reverse it: APen = White, BPen = Black or use the Invert button.
Or, experiment with other APen and BPen assignments like APen = medium gray BPen = Light Gray, for more moderate gray conversion.
Set APen and BPen to same gray, any gray, and you get a silhouette of all your pixels in that one gray.

Then start playing with color: APen = red, BPen = yellow or black.
Try any pair of colors set to APen and Bpen... it will give you a whole different version of your image.
From there you can try a few of the other default, multicolor gradients.
Finally, choose your own intermediate gradient colors(In the FX Stack window, left click on the bottom edge Gradient panel to add a color box, then RIGHT-click on the new color box to "pick a color" that will be added to the middle of the gradient.) Add more intermediate boxes and colors, etc. Get some gradient you like? Name it and save it for the future.

Yes, interesting. Powerful.

** "SPECIAL" Gradient Panel: because, oddly, this is not the normal gradient panel. This one (pictured above) is called up by clicking on the gradient strip in the FX Stack's Color Range Window. For some reason this "SPECIAL" Gradient Panel doesn't provide access to settings for, or display of the effects for SPREAD and DITHER modifiers of the applied gradient Too bad.
