assumption: the typical UGC practitioner wants transcode+delivery as one managed pipeline, not a bare encoder.","fix":"Priciest mainstream option at scale (encoding + streaming + storage all metered), and you're locked into their end-to-end stack — poor fit if you only need transcoding into your own storage/CDN."},{"rank":2,"product":"Cloudflare Stream","reason":"Radically simple flat pricing (per-minute stored/delivered, no encoding fee or egress), tus resumable uploads, bundled global CDN and player — the best value for cost-sensitive UGC apps at volume, and near-tie with Mux for teams that don't need Mux's analytics depth.","fix":"A closed pipeline with limited knobs — capped output control (no fine-grained codec/rendition tuning, weaker on advanced formats like AV1 across the board), and you can't easily get transcoded files out to your own storage."},{"rank":3,"product":"AWS Elemental MediaConvert","reason":"The scale/cost benchmark when you own the pipeline — pay-per-minute with no platform fee, deep codec and packaging control (AV1, HEVC, CMAF), automated ABR stacks, and native S3/CloudFront/Lambda integration that most large UGC platforms already sit on.","fix":"It's a job-based encoder, not a UGC platform — you build uploads, orchestration, playback, and DRM glue yourself;
