We are a small film distribution company in the process of setting up our own video streaming site. We moved from using an encoding service provider to running ffmpeg in-house. Now we want to set up a dedicated machine to speed up the process, but we need guidance for this.
THE PROCESS Input: mostly ProRes (10-20Gb), HD to 4K res, 90 mins average length. Output: a set of .mp4 files at 5 different resolutions, up to 1080. These are further processed (primarily bento4) to create multiple/ variable bitrate HLS and DASH streams, with encryption and DRM. On our office machine (iMac, 3.2 GHz Intel Core i5, 8Gb, macOS Sierra), encoding typically takes 6-7 hours per film. Ideally, we would like to cut this down to 1-2 hours. WHAT WE NEED TO KNOW 1. Hardware: what's a good hardware configuration for our needs? CPUs, cores, RAM, RAM disk, graphics cards, etc. Also, which version of Linux is recommended (or which to avoid). 2. ffmpeg setup: how should ffmpeg be compiled to best take advantage of the particular hardware configuration? 3. Video processing: how should ffmpeg be run to maximize speed and efficiency, and to produce the most suitable files for our needs? I wrote a script to create the ffmpeg command line, based on bits and pieces found in various places on the web. No doubt it's far from optimal. CAN YOU HELP? If you can answer the questions above, we would like to hear from you. Please contact me at ariel at websiteatelier dot com.
