How to Use Convex Media Converter — A Step-by-Step Guide
1. Install and launch
- Download the installer from the official Convex Media Converter site (choose Windows, macOS, or Linux).
- Run the installer and follow on-screen prompts.
- Open the app after installation.
2. Add files
- Click Add Files or drag-and-drop media (video, audio, image, or subtitle files) into the main window.
- For batch conversion, add multiple files or a whole folder.
3. Choose output format
- Use the Presets menu to pick a device or format (e.g., MP4, MKV, MOV, MP3, WAV).
- Or open Custom to select codec (H.264/H.265/AV1), container, bitrate, resolution, frame rate, and audio codec.
4. Configure advanced settings (optional)
- Video: set resolution, bitrate (CBR/VBR), frame rate, and keyframe interval.
- Audio: choose channels (stereo/mono), sample rate, and bitrate.
- Subtitles: embed, burn-in, or keep as separate .srt.
- Filters: crop, rotate, deinterlace, or apply color corrections.
- Save frequently used settings as a custom preset.
5. Set output folder and filename rules
- Click Output to select a destination folder.
- Enable automatic filename templates (e.g., {name}converted) to avoid overwriting.
6. Preview and clip (optional)
- Use the built-in player to preview files.
- Trim start/end or set in/out points for partial conversions.
7. Start conversion
- Click Convert or Start All.
- Monitor progress via the progress bar and estimated time remaining.
- Pause or cancel individual or all jobs if needed.
8. Check results and verify quality
- Open converted files in your preferred player to confirm audio/video sync, bitrate, and resolution.
- If quality issues appear, retry with higher bitrate or a different codec preset.
9. Batch automation and command-line (optional)
- For repeated workflows, create and save batch jobs or presets.
- Use the CLI (if available) with syntax like:
bash
convex-cli -i input.mov -o output.mp4 -c h264 -b 3000k
10. Troubleshooting common issues
- No audio: ensure correct audio codec and channels selected.
- Out-of-sync A/V: try re-encoding with constant frame rate or adjust audio delay.
- Large file size: reduce bitrate, lower resolution, or use more efficient codec (H.265/AV1).
- Unsupported codec: transcode to a common codec (H.264 for video, AAC/MP3 for audio).
If you want, I can produce a one-page printable checklist or a preset recommendation for common targets (YouTube, mobile, DVD).
