Raw video shooting -- worth for a wedding videography?
For a long time, the only available acquisition format for event videographers was heavily compressed 8-bit H264 4:2:0 (Canon 5Dmk2, panasonic GH2/3, etc). This format (long GOP H264, with 420 chroma subsampling) is very good as a delivery format for internet streaming. But when it comes to postproduction -- especially exposure, color corrections and color grading, you will lack the missing data. This is why high you need high quality codec with at least 4:2:0 chroma subsampling and 10-bit color space and LOG profile. Or you can shoot raw. Two years ago, MagicLantern team unlocked raw recording for Canon 5D mark III. After two years, I still know only very few videographers using it. Please, take a look at my portfolio:

What is raw good for?
-- you can fine-tune white balance and exposure in post,
-- you can color grade your films the same way as high budget commercials and films (eg. mask the skin tones),
-- you can delivery the best quality.
What problems you can have?
-- You'll need a lot of storage space. My average wedding is 2TB of data. We need to backup during the day (RAID1 external hard drive) and then a good PC storage (we use 24x4TB RAID6 array).
-- You'll need a lot of computing power (fastest CPU and GPU).
-- You'll need a lot of expensive cards (1066x Lexar 128Gb).
-- MagicLantern is still a "hack" and the 5D speed is on the edge. Be prepared for a skipped frames and on-set fuck-ups. ;) Still, this is the cheapest ways to create a professional looking video.
Do you know any photographer, who shoots jpeg instead of raw?
Do you thing this is worth it?
Do you thing the client will see the diffrence?
