Fora Soft Video Engineering Handbook
This spreadsheet turns learners, watch-hours and cache-hit ratio into monthly egress, storage and transcoding cost per learner. Our seven-volume handbook covers the full stack behind a course platform; Volume 3 explains CDNs, caching, ABR ladders and streaming economics, Volume 1 shows how encoding choices cut bitrate, and Volume 4 covers audio codecs and loudness for lectures. Written by Nikolay Sapunov, CEO at Fora Soft.
