1. The Problem We Solve
We eliminate frequent video specification errors that happen when uploading clips to AI video platforms (Runway, Kling, Seedance, Veo, Luma, Pika, etc.).
Fixes upload rejections caused by unsupported modern codecs like HEVC (H.265) or ProRes by converting them directly to universally accepted H.264.
Repackages unsupported container formats such as MOV, WebM, and MKV into clean, optimized MP4 files.
Prevents rejection caused by exceeding minimum/maximum length constraints or non-integer second lengths required by AI engines.
Converts variable frame rate (VFR) or high-frame-rate clips (60fps/120fps) into standard 24fps/30fps streams that AI models process reliably.
2. Created By (Background)
A practical tool crafted by working video production professionals to eliminate the actual headaches they faced every single day.
3. How It Works: 100% Local Browser Processing
All processing runs entirely inside your browser. Your video never leaves your computer.
- High-performance WebAssembly FFmpeg runs entirely within your local browser sandbox.
- Both original footage and converted files remain strictly within your local storage.
- Confidential corporate projects, unreleased client work, and personal videos remain completely private.
- Processing runs at native local hardware speeds without being throttled by slow internet upload bandwidth.
4. Key Features Provided
Three essential tools covering your AI video workflow from preparation to final timeline assembly.
Instantly evaluates your video codec, container, FPS, duration, and resolution against official specifications of platforms like Runway and Kling in 1 second.
Automatically identifies all non-compliant parameters and transcodes your video to high-quality H.264/MP4 with minimal quality loss at the exact target FPS and length directly in browser.
Restores AI-generated footage back to the exact frame count and duration of your original take, enabling seamless insertion into your editing sequence.
