About the video converter
The video converter takes a video file in any common container and re-muxes or re-encodes it into another, server-side and without local software install. Video format friction is one of the most common file-handling pains on the web : a phone shooting MOV when the editing app wants MP4, a screen recorder spitting MKV that a CMS rejects, an old DV archive in AVI that needs to live on the web as WebM, or a marketing team standardizing every clip into H.264 MP4 for cross-platform playback. The video converter handles those transitions cleanly. Use cases stretch from YouTubers preparing thumbnails-and-uploads bundles, to developers preparing background loops for landing pages, to teachers archiving lectures, to lawyers normalizing evidence clips, to families consolidating phone footage into web-friendly MP4. Under the hood, the pipeline is a Rust service wrapping ffmpeg with a strict configuration. We probe the input to detect codecs and frame parameters, then pick the cheapest valid path : when the source codec matches the destination container (e.g. H.264 in MOV → MP4) we copy streams directly, which is near-instant and lossless ; otherwise we re-encode with H.264 + AAC for mp4/mov, VP9 + Opus for webm, and codec-copy whenever possible for avi/mkv. The faststart flag is set on MP4 so playback can begin while the file streams in. A content-hash cache short-circuits identical conversions. What sets the BastosConvert video converter apart : no watermark, no signup, no upsell, and a deterministic ffmpeg invocation so a given input always produces the same output.
