Video Transcoding at Scale for ABC iview
summary
ABC iview standardizes incoming files into six renditions (five video, one audio) at 1500k–220k, crops anamorphic bars, normalizes audio, applies a scaled watermark, and averages 8.5 minutes end-to-end. The pipeline is built around FFmpeg + AWS: S3 uploads trigger SQS, a Node.js orchestrator stores profiles and emits per‑rendition jobs, and Go workers run ffmpeg on EC2 autoscaling instances (one rendition per machine). Daily costs vary ($34–$572); annual estimate ~A$165,000, showing the custom system works and cuts expense vs commercial transcoders.
