Before you convert
- Keep a backup of your original file before converting so you can roll back if needed.
- Review known pain points: File size limits (~2 GB) in older implementations without OpenDML extensions. Adjust your source file accordingly.
- Note the target resolution and frame rate to avoid unexpected stretching or stutter.
Quality tips
- Start with a high-quality setting (85–90%) and only reduce it if file size targets demand it.
- Pick a bitrate that matches your destination: 128 kbps for speech, 192–256 kbps for music, 320 kbps for archive copies.
- Download the result immediately and open it in the target application to verify everything matches expectations.
