I've never tried merging streams across computers so was naively just thinking that your output from each computer would be an MP4 but that makes sense.
I pulled that info. from a Netflix talk, perhaps video cameras back from when that talk occured didn't compress the video for you? Besides, isn't IMAX all intra-encoded? It was my understanding that IMAX films are actually just a series of J2K images, so I would imagine that the video cameras used there would also be intra-encoded.
- dylan604 3y agos/increase/decrease/ i was thinking increased the encode speed 9x, but typed increased encode time. i also swapped the number of segments by segment duration. 9 segments of 10mins = 9x increase in performance. Sounds like you are confusing Netflix' recommended formats for acquisition vs delivery. Cameras capture RAW formats (rarely is it uncompressed though), and the post houses use that as sources. The post house/color correction will the create the delivery formats which is typically ProRes. RAW is not a friendly format for distribution in the slightest. The full workflow from camera original to what ends up being streamed to the end viewer changes formats multiple times through the process.
