So I have a bunch of screencast videos which switch between two color types (or whatever it would be called) throughout the video. I have created a color balance thing that give the video consistent color throughout the whole thing. The problem is, though, that I want to automate this process.

Basically I am looking for someone to point me to resources for the adobe SDK in order to add color correction based up on the color of a few pixels (since in all of the videos, top bar never changes)

To get a better idea, here is the color issue I'm talking about

this:

vs:


Running Premiere Pro CC 2015 (or CS6 if i say so)
On windows 10 with:
i7 2600k at 3.4 GHZ
GTX 560 ti
16gb 1333mhz ddr3
in a case
with a mouse and keyboard.

Hi Natalie...

if you load each of the clips into your source viewer one at a time...


then from the effects panel...

add you color correction necessary to make them consistent....

they will then have those effects applied through out the timeline...

and if you adjust then again by loading them into the source...then all instances in the sequence will update to reflect that change...

this is called adding master effects and some people refer to it as source side effects...

anyway...this should do the trick...

no SDK or scripting needed....

That doesn't help at all though. The video clips themselves switch between the two gamma levels. I have to find the points where the video switches, and add the color correction on only that part. I could go through and manually make cuts at the point where the colors change, but i am simply looking for a more efficient way to do it to >100 videos that have the same problem.

ok.

sorry I misunderstood about the changes happening within each clip.

So....you want to dynamically adjust the gamma based on sample of an area....


hmmmm...

Auto color, auto levels, or auto contrast may be a direction to go...

anything thru scripting and analysis is probably much better handled with After Effects....I don't thin PPro is robust in this area.

how are your images compressed?

is it the blue you are concerned with?

you might achieve the result you want by keying out the blue
and then layering over a consistent blue background...that would negate the changes you are seeing....

it's a stretch....but maybe....

or....

if the changes are abrupt....

split the clips, move all those that match on to their own video track in same time sync as original (in other words leave gaps)

then nest that track...

inside that nest....you can add an adjustment layer containing your correction and it will aply to all the clips there...

this correction will be seen in the parent timeline...

if necessary, do the same with the other set....

so you parent timeline will end up with two nested tracks, each one corrected to make them match....

there are some approaches...


hope that helps...
