Performance Tips
Optimizing Conversion Speed
- Video conversions — Use hardware acceleration if available:
"MP4": "ffmpeg -hwaccel auto -i '{input}' -c:v h264_nvenc '{output}'" -
Batch conversions — Process in smaller groups if memory is limited.
- Image conversions — For large batches, reduce quality slightly for faster processing.
Quality vs. Size Trade-offs
| Format Type | Best Compression | Notes |
|---|---|---|
| Images | WEBP | Best compression with good quality |
| Audio | AAC 128k or Opus | Good quality at lower bitrates than MP3 |
| Video | H.265 (HEVC) | Better compression than H.264, but slower encoding |
| Documents | PDF/A for archival | Regular PDF for sharing |
