You're WB seems right on...did you make sure and set WB for each scene?
What did you use for the color style when shooting this? Was it a normal Canon picture style, or did you shoot flat like with a Marvels Cinestyle...and do color correction/grading after in post? If so, what did you do color with?
What are you using for editing?
Anyway, I very much enjoyed the video...looked like a fun bunch of folks having a great day and you captured it quite well.
I used manual white balance on everything/adjusted by eye. As far as color style I used Canon Faithful with pretty much everything dialed down with the intent of pushing it in post.
I'm going to work on another version and address everyones notes.
Thanks Again !
