Really? Not according to this layout. It seems ProRes LT is lesser quality than just 422. I’ve always been under this impression assisting editors. For DSLR maybe there’s not much of a difference, but there has to be for C300 and AF100 material?

“ProRes 422: This is the format I recommend for anyone shooting DSLR, HDV, AVCHD, XDCAM EX, XDCAM HD, AVCAM, or P2. Great image quality, with file sizes 30-35% smaller than ProRes 422 HQ. Since the DSLR images start as H.264, which is already quite compressed, ProRes 422 most closely matches the original image quality.
ProRes 422 LT: This is the format to use if you have tons of footage, need to edit using smaller (i.e. less storage space) hard drives, or are going to go thru an off-line to on-line process.”
