Premiere for Color Correction

Hi,

I've been encharged of the color correction of a short film for college and mostly in my life I used Premiere since I never needed something more dedicated like DaVinci or Ae. And it's pretty good at it too. Our professor keeps saying that one of these two will be needed to fix the color, but maybe that's because he needed to teach After Effects and DaVinci this semester, and this could confuse some to which kind of software is really needed in each given situation.

I need to make the colors like first image. You can see an example of what I did on the second image with Lumetri and Three Way Color Corrector

Could I keep going on Premiere alone? And any tips you may have are welcome.

You can drag/drop png & jpg screen-grab pics onto your reply box so they show up "here" and we don't have to go to some link for them, it's a bit easier.

Yes, you could do this with Lumetri alone. I do some work in Resolve and AfterEffects, but would not normally use Ae for color correction though years ago I did for a while. Lumetri has come a long way.

For matching shots ... in the Color Wheels tab, note that it is now called the "Color Wheels & Match" tab. Using Comparison view in the program monitor, you can set so you have side-by-side or a "wipe" style view between two frames. Set the first one to the clip you have already set the color for, then move the CTI bar to a frame in the clip you wish to match to that other clip, then use the "Apply Match" button. It will get somewhere close ... if the shots are fairly close, it can get very close to matching. It uses the Color wheels to do so.

Then you can use all the tabs of Lumetri to get it even closer. For this type of work, I always have the RGB Parade scope and the Vectorscope YUV visible. Some color work needs to be done by matching scopes, some by using the eye on the image. Between them ... trust the scopes more.

The new Curves section ... with various curve type options ... is an amazing new tool. You can say select the skin tones, and move them to a more natural hue by dragging up or down on the line between the outer 'set' points. All sorts of things done there.

Thanks for the tips! The Curves and Match seem to be really helpful. I was waiting because they said they were gonna send another project, so I would tests your suggestions and then comment, but it's taking too long haha. i will check the links too. I know that Ae has color correction options like gamma, tilt, gain. At least I didnt find with those names, but there are matching effects on Premiere. I mean, very likely premiere has gamma option haha. But not like gamma for blu, green and red seperately, right?

Oh, and what did you think about that color correction so far?

Definitely for this, Lumetri can blow out "Three Way" for both range of work and speed.

First image ... sat is still a bit too high, especially in those yellows. In the Lumetri scopes, how far are those yellows surging out to the bounding box in the Vectorscope YUV? Maybe all sat, but especially the yellows, need some lowering.

Next, still first image ... for my taste, blacks are pretty ... black. This is a diffused-lighting siguation for most of that scene, blacks should be not quite fully down to 0 on that left-side scale in the RGB Parade scope. Maybe more like around 8-10. If you can, I'd roll the whites down just a bit also. You're playing with pinging out the top values.

Bottom pair ... this would be a fair start for the first control or two. But not far enough to keep against what you can do quickly in Lumetri, dump it. You have some ideas though of where it needs to go, which is good.

This is where fixing the first shot, then using that as the Reference in the Lumetri Color Wheels & Match tab with the monitor set to comparison view is gonna be your best friend. It will use the color wheels controls for Shadows/Mids/Highs Luma/Chroma to match as close as that tool can get. Typically 80% of the way "there" or at times better.

Then I'd suggest going to the Creative tab while you have both RGB Parade and Vectorscope YUV up. With the monitor in the 'wipe' mode of the comparison view, look at the scopes with the reference image showing whole screen, wipe to the second shot whole screen. Note the positions of the bottoms & tops of the waveforms in the the RGB Parade especially, and use the chroma controls in the middle of the Shadow/Highlight wheels to see if you can match the shape/positions first the bottoms of the three waveforms closer between images, then the tops.

Past that I'd go to the new Curves tab, and say use the Hue Vs Sat (top rectangle) to control excess saturation hues first, then maybe up sat in hues you'd like more color to grab the eye.

Use the Hue vs Hue (second rectangle) to say pull skin tones closer ... make several points in the skin tone areas, and move them up or down as needed to slide skin tones close but not on the i-bar ("Skin tone line") to that line. Also, really obvious colors like the one girl's cyanish back-pack, you can modify that hue to be closer to another frame with this tool also.

I'd also recommend going to the Sat vs Luminance tool, and set a point about 20%-25% in from the left, then grab the far left end of that line, and pull down maybe a third of the way to the bottom or more. This rolls off saturation in the shadows more closely to the way film and our eyes see color vs brightness. Then set a point about 10% in from the right, pull down the end of that side a third of the way, and make another point in-between them and pull up the middle to get a more curve line. This rolls off the saturation in the very edge of highlights into whites. Which both fits our eyes better and tends to clean up some slightly odd colors in highlights.

In general ... when working with "thin" media, 8-bit from DSLRs/mirrorless and such, using two or more tools to say lower contrast or modify saturation results in both a more natural look/feel and less artifacting than using one tool for anything.

So I had two days to do it. The professor enjoyed a lot. Probably didn't know it was made on premiere. I used a lot of the things you recommended it and not knowing most. I used the curves, tried to select only yellow in on part to turn it down, used white balance, temperature and tone, used match tab and tried to correct most of it using the vectorscope. It was pretty intense.
