Hey, sorry to revive an old thread but I stumbled upon this while doing some midnight research on making more edit-friendly proxy options out of 4K footage.
I own a couple of Atomos recorders and work almost exclusively with Vegas. I don’t know if it makes a difference, but Atomos does NOT only record Prores. These days all of their recording products are licensed out of the box to record both ProRes and Avid’s DNxHD. I found my PC is much happier with the Avid files, and have them all set to DNxHD by default. I was aware that Vegas sometimes chokes on ProRes, but does it matter if it is another codec that happens to exist in a MOV container? I thought I had effectively gotten away with using my Atomos recorders by picking the more PC friendly codec, but now I realize that its because I usually use the recorders for long-form sessions (hour long concerts, etc), and only import a handful of files at the end.
Now you got me wondering, is Avid’s codec any better than Apple’s in regard to Vegas? Will it still choke once I load 100+ files if that ever happens? I know DNxHD can also exist as an MXF, and is not exclusively a quicktime format. Is QT being invoked simply because of the mov extension? I wonder then, can I just batch rename the extensions to MXF and then have it be universally friendly with Vegas? The Atomos recorders are too useful and I refuse to believe that they can’t work harmoniously with my favorite editor of all.
