Exporting for Web: Best Settings in AVS Video Converter
Quick overview
Use H.264 (MP4) for widest compatibility, WebM (VP9/VP8) for smaller files on modern browsers, and MP4 for social or CMS uploads. Match source resolution/frame rate where possible and prioritize bitrate and codec settings for the target delivery (streaming, social, or download).
Recommended presets (use as starting points)
| Use case | Container / Codec | Resolution | Frame rate | Video bitrate | Audio codec | Audio bitrate |
|---|---|---|---|---|---|---|
| Web streaming (YouTube/ Vimeo HD) | MP4 / H.264 | 1920×1080 | Match source or 30 fps | 8,000–12,000 kbps | AAC-LC | 128–192 kbps |
| Social & fast uploads (Facebook, Instagram) | MP4 / H.264 | 1280×720 | Match source or 30 fps | 4,000–6,000 kbps | AAC-LC | 128 kbps |
| Mobile / low bandwidth | MP4 / H.264 | 854×480 or 640×360 | 24–30 fps | 800–1,500 kbps | AAC-LC | 96–128 kbps |
| Browser-native small files | WebM / VP9 | 1280×720 | Match source | 2,500–5,000 kbps | Opus/Vorbis | 96–128 kbps |
| High-quality download / portfolio | MP4 / H.264 (2-pass) | Keep source | Match source | 12,000–20,000 kbps | AAC-LC | 192–256 kbps |
Step-by-step export guide in AVS Video Converter
- Open AVS Video Converter and add your source file.
- Select the output format: choose “MP4” for H.264 or “WebM” for VP9.
- Click Advanced (or Settings) to open codec options.
- Set resolution: choose “Original” or manually enter target (use table above).
- Set frame rate: choose “Same as source” or set 24/30/60 as needed.
- Choose encoder: H.264 (x264) for MP4; VP9 for WebM.
- Bitrate settings:
- For consistent quality and predictable file size, choose Average Bitrate (kbps) and enter value from the table.
- For best quality-per-size, use Multipass (2-pass) encoding if available.
- Rate control: use CBR for streaming platforms requiring constant bitrate; use VBR for better quality-size balance.
- Enable CABAC/Trellis/Deblocking only for H.264 when quality is prioritized over conversion speed.
- Audio: set codec to AAC, bitrate 128–192 kbps, sample rate 44.1 or 48 kHz.
- Container settings: ensure MP4 file profile is compatible (Baseline/Main for older devices; High for modern).
- Save the preset if you’ll reuse it, then convert.
Optimization tips
- Match source resolution/frame rate whenever possible to avoid resizing artifacts.
- Use 2-pass encoding for final exports where quality and file size matter.
- Disable unnecessary filters (denoise/deblock) unless the source needs them.
- For streaming, prioritize slightly higher bitrate to avoid compression artifacts during motion.
- Test one short clip at chosen settings before batch exporting.
Short checklist before upload
- Play the exported file to verify audio/video sync and quality.
- Check file size vs. platform limits and adjust bitrate if needed.
- Confirm color and aspect ratio on desktop and mobile.
