Developement into media Artifact

I have started looking into films on Vimeo and Youtube which use split screens and the Triptych style. Its become quite popular recently with a new feature called Split Screen X for Final Cut Pro X, which easily allows users to create this layout, as well as using diagonal cropping, unlike in After Effects and Premiere Pro which have to be done manually using a cropping tool and other features which i'll be researching tutorials later in the week.

I loved the diagonal cut and wanted to include that into my film, rather than the typical rectangular shapes i would have normally used as I didn't want it to be too repetitive and ordinary. As instead of just 3 screens I want to experiment with numerous clips playing on one screen, and interchanging the layout throughout.

Looking back I remembered I'd seen a music video which used the same split-screen effect -Hey There Delilah- which I'd used as inspiration in the mini brief when i did my Autumn Triptych.

However looking back at it, the colour and tone is what I liked most about it, as its quite dull and saturated, which I prefer to sharp strong contrasted colours as it connects with the tones of the music, which is exactly what I want for my film.

******UPDATE******

So I've just downloaded a free Trial of Adobe Premier Pro CC, and i love the layout compared to the norm. I also chose this instead of After Effects or Final Cut as I know the basic tools and effect i need to edit my film, especially within the time limit we have.

I have just watched some tutorials on Youtube about different cinematic effects and colour grading, and I'm in the middle of experimenting now.

I've noticed a lot of the footage i have already captured have quite different colour tones to them, as in some clips I have used the orange filter clip in the LED light, and then some parts i had to use natural lighting, and candle light to get the correct affect i wanted as a silhouette of my cat against the outside window, and then ECU's of my eye, and a slug outside.
For example below, the two shots are extremely good quality and the colour is quite contrasted and normal, whereas, the two images below it have a lower quality as there it no source of filter light.

Due to the different qualities and different lighting I will have to experiment with using colour grading, adding noise/blue, and saturation and contrasting for each different clip to have the same consistent look and tone too them.

Colour Grading - I'm using the Fast balancing colour tool and changed the hues of the clips to give it more a a purple gradient. I've had to adjust the contrast and saturations to all the different clips as a lot of them are very dark, some extremely in focus and sharp. 

In some cases (EYES CU above) I had to add noise and a blur to it, to try and make them all similar

Adding Colour Leaks- I LOVEE these light leaks. I've been having a lot of fun experimenting with these and So far i have added a couple of them to the clips one where the cat opens his eyes, just to create a notion that something has happened, and a starting point, as you will to the film. and then I will use it during the end of the film, as well as superimposing the clips changing the opacity and blend modes. Again just experimenting, because I love the idea of using the blend modes to overlap different clips, especially out of focus lights.

Knowing I wanted to use diagonal cropping, I watched a 10 minute long tutorial in German to try and understand how to do this, It was difficult, but I think i've sort of grasped it.
I added the Eight-point Garbage matte effect onto the panel, and after to fiddly and very time consuming effort with figuring out which angle is where I've finally succeeded in creating a diagonal crop, though it doesn't actually have the little white frame between the two clips, which i did originally want, but i think i'm far too irritated by this effect alone to even try and change it again! Here's the overall look, which i love!
