This article details technical lessons learned from building a video transcoding pipeline, focusing on two specific bugs related to PHP memory management during cloud storage downloads and filesystem I/O performance in containerized environments. It also highlights an optimization using FFmpeg's `filter_complex` for single-pass multi-resolution encoding.

In this case, PHP buffering and container volume mounts created hidden costs that only showed up on a 170MB clip and during repeated FFmpeg writes. For streaming teams, the broader point is that upload/download paths and temp storage choices are load-bearing parts of the stack, especially when workloads involve large files and thousands of I/O operations. What to watch: whether temp files live inside the container or on a mounted project directory, and whether FFmpeg is decoding once or once per rendition.
