## What this tool does
Two-pass H.264 compression that hits an exact MB target — email, chat and portal compliant.

## Typical user problems
- Upload forms, email and messaging apps enforce hard video size caps. Hand-tuning bitrates means codec jargon and repeated failed exports — you need the file under the cap once, with sane quality decisions made for you.
- Email caps attachments at 25 MB total. Your 4K phone clip is 400 MB. You need a compressed MP4 that mails cleanly — with the resolution policy handled for you.

## Parameters
- target_mb: number (range 0.5-500MB), required. 目标大小. 上传系统允许的最大值

## Pricing
- Watermarked preview: free, no login required
- Final clean output: $2.99 one-time per task
- Require login (email/phone OTP) to complete payment
- Result available for download 24 hours after payment

## Limitations
- Max input 500 MB; duration-driven bitrate math
- Output MP4 (H.264 + AAC 128k, faststart)
- Extreme caps on long videos hit a physical quality floor — the error tells you the minimum
