This is wonderful Alex!
Thank you for all your efforts on this amazing creation. I would like to mention that my hobby is underwater videography. And any questions i have had in the past have mostly been answered by this forum's topics which I am quite grateful for. And would like to add that the benefits of shooting raw underwater seem IMHO more beneficial than even on land.
The main 2 issues of light loss (full frame advantage on 5dmIII) and the fact that every 10ft (3m) you lose another source/color of light has made this process quite appealing and pleasing for me. I do admit the process in post is time consuming but for me it is worth the extra effort. There is nothing more disappointing that spending so much money on a trip and not getting the full experience on video for others to see.
My experience and benefits:
No need for red filters - cause even more loss of light (lumens) when added
Macro flips are also replaced with magic zoom (unfortunately i realized on my vids that it was not centered and was using V1.1.3 as advised)
You can also take pictures - which has now become such a pleasing addition to my dive experience
Bigger sensor than camcorders and far less expensive that other raw capable video cameras (with smaller sensors)
It's more beneficial to work around and master the limitations present in ML for video on the 5D than using a real video camera when comparing the results.
WB balance is a one button correction in post (especially when you have had the privilege of trying out capture one!)
I will hopefully be able to finish my video of Palau, Micronesia within the next few days and post a link from vimeo onto this site for anyone interested to see what an amature like me has been able to create. But please take into consideration that it is my first video in raw and I am no professional in any way or meaning of the word. I will have it mixed with some GoPro footage and Aerial footage but it will be quite noticeable which is which and is mostly (90%) my raw footage

My process is the following: Please correct me or educate me if you think I am making a mistake. I have read many topics on this forum so it's pretty similar.
1. Shoot in raw (24p) in 1920x1080
2. Examine the results using ML Viewer (mark my ins and outs or basically what's usable whilst on the viewer) and adding the frame numbers (in/out) to the file name
3. Convert using RawMagic
4. Import into Capture One/Lightroom
5. Do all color corrections and image fixtures here (even lens correction)
6. Export in tiff 8bit (find it is more than good enough when compared to 16 bit) and less time consuming
7. Convert into ProRes 422 (not HQ) in Compressor
8. Import into Final Cut Pro X for turning it into a movie and for image stabilization if needed (does not always help)
9. Export as ProRes 422 and not higher since the video is already way too large for uploading
10. My next process will be to bring it back into Compressor to turn it into a vimeo uploadable format like H.264 and then upload
Ill upload my result soon and try to link it to this post as an update if i figure out how.

I just joined!
Thanks for taking the time to read this!
