| Okay, need the collective Borg mind here on visually lossless, low AE impact codec to turn PNG sequences into video file. What AE accessible codec can render out a under 10 megabyte, greater than 8-bit, visually lossless file? We've had no success with ProRes, Avid, QuickTime, AVI. Compromise would be 8-bit file (but process in AE in 32-bit) as the source PNGs are 8-bit. Noise and artifacts are a huge concern as we have 1.1 million PNGs, each of in motion over background of 4 million individual background galaxies (23 TIFF 10,000 x 10,000 pixels tiles). DETAILS: We are preparing to render out the 8K native fulldome of the film, recomposed for the 180 view. We have reached the (in)famous section so many folks here helped render. Those might recall it was 40 second shot with 1.1 million PNG files and a bunch of large TIFFs. That render at 5.6k was a 5.5 years on the fastest workstations of two years ago. Give we are at 8K, that's a real problem. We had the idea that turning the dozens of sequence of PNG sequences into movie files might dramatically improve things. Testing has revealed this to be true as the PNG files, most are so tiny, even the fastest SSD disk IO speeds are floppy disk era read speeds. Here's the problem - AE 2019 has RAM issues. If we render the PNGs to 8-bit uncompressed QuickTime, that's about 160GB for each 30,000 image sequence. For testing, it we make it a 700MB MP4, render speed nearly doubles on a 64GB box. However MP4 compression introduces noise and artifacts as well as affects our masking and we are going out to 12-bit DCP. Also, the frame size is 1316 x 1316 pixels at 30.000fps (it must be that for our purposes) Best,  stephen van vuuren 336.202.4777  http://www.insaturnsrings.com/ http://www.sv2studios.com/ http://www.sv2dcp.com/  A film is – or should be – more like music than like fiction. It should be a progression of moods and feelings. The theme, what’s behind the emotion, the meaning, all that comes later. –Stanley Kubrick What AE accessible codec could render out a under 10 megabyte, greater than 8-bit, visually lossless file?
