Learning video color grading/correction. Would like some crit on this 17 sec clip.

[CrimsonChin]

Did manually (levels/curves/vibrance/3 way color adjust, and a bit of auto masking)
I've never tried in depth like this before. I've only used a basic preset prior to this. If it looks amateur that's cuz it is :P

I tried to make each shot convey a different mood/feel, hopefully it is noticeable.

Thoughts and criticism?

I know it's just flowers, I should try it with some shots of buildings/streets etc.

Bonus (don't have original video, but this one I tried to create a cliche epic blockbuster thriller look)

Second video Is clearly more vibrant.

Seemed like you were going for a warm, nostalgic vibe for the first video, but I think you're putting just a *bit* too much blue in the shadows; while they do punch up the image a bit and add more color contrast (which is why so many modern action movies do it), they feel sort of artificial, which sort of betrays the subject matter.

It's a lot of natural plant-life and I feel like keeping it more natural -- while still pushing out the vibrant natural colors in the scene, even if there's not much blue to work with -- would do it justice. Not saying keep the colors EXACTLY like real life, just try to emphasize a more natural color pallet for that particular subject (yellow-greens, reds, yellows, pinks), and if you see a rare speck of blue in the shot then take advantage and add some vibrance/brightness to it to make it pop more.

Always be conscious of your dominant and opposing color pallets, it's different for every project and every shot. If you force the opposing color too much (like trying to push blues into a really orange scene, or trying to push reds into a really blue scene) then it pulls the viewer out of the shot IMO, it creates an unnatural tone. That may just be personal preference though, I don't much care for heavier "atmospheric" color grades.

tl;dr - I'm a huge dick about color grading.
