Grading and Compositing

This trimester, we were required to do a range of complicated colour grading and motion tracking exercise. During our TVC class workshop, we shot a perfume bottle in close up on a dolly motion. This shoot was conducted to demonstrate the style how products are perceived to be shot.

Post filming, the footage had to undergo an appropriate colour grade and the perfume logo too had to be replaced with different one. The trickiest part comes when all these effects had to be kept in tact on the frame accordingly as we have single shot in motion.

The first project setting was to change the 8 bit layout into a 32 bit layout. This is done to keep as much quality as possible form the 4K video file. after dragging the footage and working assets into the composition file, we go through the remaining steps as follows.

  • We click on the inbuilt curves option from effects and keep tweaking the primary colours until we arrive at a pleasing illusion of the whole footage.

  • In order to provide a contrasting grade for just the perfume bottle, we motion track it using the ‘track in Mocha’ plugin. This effect is found in animation scroll.
  • after changing the plane to trax, we click on the ‘x-splain’ to get the shape (perfume bottle) we want for the mocha to track.
  • After tracking is done both forward and backward, minipixels is changed to 20%, after which the mocha data is exported by copying it to the clipboard.

  • back in AE, we create a null layer and host the exported mocha data on it. While rendering for quality, we delete the stray keyframes.

  • These are the keyframes that occur before the desired shape enter the video frame, so we get rid of them.
  • now we create a new track matte layer to trace the shape of the bottle using a pen tool. Now we animate the mask to be in motion along with our bottle by adding a position keyframe every second.
  • we now duplicate the original footage and name it alpha tracking matte. We now grade the new layer to get the desired colour of the bottle in contrast with its background that appears on the original graded clip.

  • now we import the new chanel label. This label is dragged into the composition under a layer of its own. This layer is linked with the null layer’s animation data.
  • we now use the ‘CC pin’ option from the effect menu to distort the chanel label to fit into the perfect dimension with the bottle. We make sure that our label completely cover the old label and any additional animation required is now done use the keyframes.
  • We now use the curves again to grade the label until we get the desired illusion.
  • We create a new composition where with a HD resolution. We drag the completed composition into this and squeeze to into 1920 x 1080 pixels.

Once we complete all the above mentioned steps, we are just one step away from export. We queue this export into media encoder. We now select the apple pro res 422 configuration and apply it to the queue and finally EXPORT!
