Ashampoo Video Converter is not a dedicated file repair tool, but it can fix unplayable videos by re-encoding the video stream or changing it into a compatible format. This method works if your video is unplayable due to missing system codecs, an unsupported format, or a mildly corrupted file header.
However, if the video data itself is severely broken, a standard converter will fail, and you will need dedicated data-reconstruction software instead. Step-by-Step Guide to Fixing Videos via Conversion
You can process your files through the Ashampoo Video Converter Interface using these steps:
Import the broken video: Open the software and click Add videos, or drag and drop your unplayable file directly into the application window.
Choose a highly compatible format: Click Select format. To ensure maximum compatibility across all devices, select MP4 or choose your specific target device (such as an Apple or Android smartphone) from the pre-configured list.
Apply image optimization (Optional): If the video is playable but severely dark or distorted, use the built-in video optimization sliders to adjust the exposure and contrast before processing.
Process the file: Click the Convert button. The software will rebuild the video’s index and container structure from scratch.
Check your results: Once a green checkmark appears, navigate to your output folder to play your newly generated video file. Limitations: When a Converter Isn’t Enough

For severely damaged files: Use Stellar Repair for Video (offered in partnership with Ashampoo), which uses a “Sample File” method to rebuild entirely broken video headers using data from a working video shot on the same camera.
For general file damage: Try free multi-purpose utilities like the built-in index repair features found in the VLC Media Player desktop app.
