I really hope that someone can help me out here. I was looking for a way to change the color of an object from dark brown to red. The sequence is only a couple of seconds long, the object in question is a bag that is being held in one hand, and then walked out of the screen (no crazy throwing around or anything like that, also the surrounding area is clearly a different color and not too busy). Here is the bag:
I tried getting inspired by tutorials online (I wasn't set on doing this in Premiere at all), and the overwhelming consensus was to use Lumetri Color in Premiere Pro. This is the tutorial I used, and based on the comments underneath and the tutorial example file, it seems to work great for everyone.
Now when I tried to do the same (using Premiere 2020), I failed terribly. Right away I encountered a couple of challenges:
1. Since a similar color to the bag is being used by another object, I was forced to use a mask for the bag.
2. Although the tutorial said it would be enough to make a broad mask outline around the object, that was not the case for my clip, since the shadow cast by the bag would be detected by Premiere as belonging to the bag and turned red, so I had to make sure to exclude the shadow and draw a very neat mask.
3. Then I was hoping for the mask to be autodetected on subsequent frames, and here are my settings:
This tool failed completely at adapting the mask frame by frame, although the movement was minimal and the background didn't seem to clash. Here is what the next frame would look like:
As you can see, the bag's shadow ended up being changed to red, and the mask was completely off for no obvious reason. This would continue for every frame, so that I ended up spending 10 hours manually adapting each frame until the end of the clip since I was pressed on time to get this ready (luckily the clip is only a few seconds long, but still, 10 hours gone...).
The result looked good, but the amount of work involved was beyond anything I would want to do again. I have two more similar projects to this in the pipeline and am really hoping that someone here might be able to point me in the right direction to avoid a similar high-maintenance editing project. Thank you in advance.
This job "seems" minor, but the problems you raised are anything but.
AfterEffects (Ae) is probably the best bet for this, as it has a much better full-on rotoscoping process for this. Including mask tracking that is vastly superior.
Thank you, I will definitely give it a try for my next video, hopefully it will give me a smoother ride!

You are masking Lumetri.
You need to use HSL feature within Lumetri.
Sorry not to have made it clearer what I used, below a screenshot, I was using HSL secondary throughout (picked the color of the bag, fine tuned which color I wanted it to be, then used the mask tool in a hope that it would autodetect the same for subsequent frames). Is that what you meant or did you refer to something else? Thank you.
