compression for B&W Festival entries via internet
An animator I work with wants a compressed file to upload to festival websites for jury viewing. If accepted she would send a BluRay, DVD, or high quality QT file for play in the festival depending upon what they ask for. The show is B&W with gorgeous, fine gradations in moving shadows over a largely featureless wall. The predictable problem is when I compress to H264 with web specs or the like, the chiaroscuro turns into nasty movings bands. Maybe an insurmountable problem?
I tried several presets out of PP CC’15 such as the Vimeo variants and then a ProRes (LT) file which looks good of course, but weighs in around 1GB for a 4:30 show.
I know what to expect from camera and post codecs, but know little, if anything, about compressing for the web. Please give me a clue if you can. A bonus would a good source of information about web and other distribution compression schemes so I can educate myself a little.
Thanks for your help.
