However, I would suggest, if you have the latest version of Resolve around, see if it will load up your source file and transcode to DNX or ProRes.

Well Handbrake really maxes out the cpu temp on my old 2013 iMac. I made a few passes to test but they must still be really compressing the files. Source file 160GB and converted file 5GB. I realize codecs like H.264 are way more efficent than whatever the original file is but that seems to good to be true. I'm playing around with the various settings in handbrake. I've noticed the media info analysis of some files lists the codec and some don't. I don't know if that is based on lack of meta data or what but I've seen that over the years.
Here again is the Media Info just related to video:
<dummyfile.0.part>
As Previously suggested a bit of Googling and I found this:To decode compressed 4:2:0 video, use one of the following uncompressed pixel formats.
Pixel Format Description YUY2 As described in 4:2:2 Video Pixel Formats, except that two lines of output Cb and Cr samples are produced for each actual line of 4:2:0 Cb and Cr samples. The second line of each pair of output lines is generally either a duplicate of the first line or is produced by averaging the samples in the first line of the pair with the samples of the first line of the next pair.
From this it seems to imply that the YUY2 is an uncompressed pixel format. That sounds like something good. Now to play around with the settings.
This Google thing seems pretty informative. Over Xmas I used it to discover that the Bake a Bone company no longer exists to sell pre packaged Dog Treat Recipes and then Google provided me with a site with home made recipes for Dog Treats. I'm not sure what Codec the treats were but they took Wheat Flower and according to the Pups they were definitely Broadcast Quality. ;-)
