I have 6k footage that is sitting on a very fast PCI SSD that loads each frame almost instantly when clicking through it inside After Effects (with no effect applied). That same exact footage takes about 2 seconds per frame to load when inside Mocha Pro - this is not when any tracking is happening - this is just randomly clicking on a frame. I have a 16GB AMD Radeon Pro W5700X, 16-Core 2019 Mac Pro with 192 GB of RAM. I’m trying to figure out how to optimize Mocha Pro so this will load at least MUCH closer to what After Effects is natively able to do. Both AE and Mocha Pro are using the same fast PCI SSD drive for caching, so that’s not the issue. I’m running the latest version of Mocha Pro 8.0.3.
Throughput I’m seeing - After Effects is reading about 850 MB/sec, and Mocha Pro is about 60 Mb/sec. So, almost 15x slower. It’s easily the biggest bottleneck I’m facing. The frames I’m using are about 120 MB each.
