How this service works
Takes a video of up to 10 minutes and 24 MB and returns it as MP4 with H.264 and AAC and fast-start for web playback, or as WebM with VP9 and Opus, scaled down to max_width if larger (aspect ratio kept), at high, medium or low quality, optionally with the audio removed. Input and output facts — container, codec, resolution, frame rate, duration and size — are measured and returned with the size ratio. Output inline as base64, max 24 MB. Runs locally with ffmpeg; nothing leaves this machine.
Output
A JSON response containing the base64-encoded output video (up to 24 MB), along with metadata for both input and output: container format, codec(s), resolution, frame rate, duration, and file size, plus the compression size ratio between input and output.
Example use cases
Web-ready MP4 from raw footage
“I have a 5-minute raw video at this URL: https://cdn.example.com/raw_footage.mov — can you transcode it to MP4 with H.264 and AAC at high quality, scaled to 1280px wide, so it's optimized for fast web playback?”
Silent WebM for background loop
“Take this video from https://assets.example.com/background.mp4 — it's about 2 minutes — and convert it to WebM with VP9 at low quality, max 960px wide, and strip the audio completely so I can use it as a silent background loop.”
Compress large video for sharing
“This video at https://uploads.example.com/presentation.mp4 is way too big to share — it's about 8 minutes. Can you re-encode it to MP4 at medium quality, keeping width under 1280px, to shrink the file size? Tell me the before/after size ratio too.”
Technical details
Endpoint
POSThttps://medien.halowerk.com/v1/video-convert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need server-side, privacy-preserving video transcoding (nothing leaves the machine) with deterministic output format control — specifically MP4/H.264/AAC or WebM/VP9/Opus — with measurable metadata returned alongside the encoded file. Prefer it over client-side solutions when you need consistent codec targets for web streaming (fast-start MP4 or WebM), when you need to strip audio, or when you want file size reduction metrics. Best for short-to-medium clips up to 10 minutes where inline base64 return is acceptable.
Side effects
- Video exceeds 10-minute or 24 MB limit — request rejected
- Base64 input exceeds 12 MB character limit — payload too large
- Unsupported input codec or container not decodable by ffmpeg — conversion fails
- Output after encoding still exceeds 24 MB inline base64 limit — error returned
- Invalid URL or inaccessible source — fetch failure
- Requested max_width below 160 or above 1920 — validation error
- duration_minutes not matching actual video — potential billing mismatch
