Color-correcting old MiniDV footage
on Dec 18, 2017 at 6:00:00 pm

I'm editing footage shot in 2001 on a Sony PC10 (MiniDV 720X480).

Does it make ANY sense to transcode it to a higher res for color correction in Resolve? Or employ any other workflow modifications to get the best results?

THANK YOU!

if it was captured in 8 bit, upgrading to 10 bit isn't going to help grading. cineform will just make it easier to scrub the timeline. Now if you do some noise/grain reductions, its dithering algorithm may require exporting to a 10 bit codec for banding removal.

Not to me, no. It's just a very simple 8-bit YUV format. You could transcode to ProRes 422 (or an equivalent DNxHD format), but I wouldn't necessarily believe you're going to get anything more out of it. You can't get more out of 8 gallons of water by pouring it in a 10-gallon barrel.

There is a new de-banding tool in Resolve 14 that can selectively eliminate the ugly 8-bit artifacts that sometimes happen with these formats, and it does help somewhat. I find a lot of noise reduction and sometimes frequency-selective blurring & sharpening can also take the edge off.

There's also an old green-screen trick of converting the color-encoding to YCbCr and blurring the color components (leave the luminance alone or sharpen it) that will trick the eye and some compositing processes into thinking it is dealing with a higher bit-depth image. This only works when you are working within a floating-depth application.
