Ultimate Video Upscaler
Upscale videos to 720p, 1080p, 2K, or 4K with a simple upload. This is the most advanced video upscaler in the world, delivering the highest output quality and exceptional frame-to-frame consistency. Also check out Video Upscaler Pro, Standard Video Upscaler, and FlashVSR for other options.
Why It Looks Great
-
Temporal consistency Minimizes flicker and ghosting across frames for stable motion.
-
Detail reconstruction Restores fine textures (hair, fabric, foliage) and sharp edges without over-sharpening.
-
Artifact cleanup Reduces compression blocks, ringing, and shimmering in challenging shots.
-
Motion-aware upscaling Preserves fast action and camera pans with fewer motion artifacts.
-
Natural look Balances perceptual quality with crispness to avoid plastic or overprocessed outputs.
Parameters
| Parameter | Required | Description |
|---|---|---|
| video | Yes | Input video to upscale (URL or upload) |
| target_resolution | No | Output resolution: 720p, 1080p, 2k, 4k (default: 1080p) |
Limits and Performance
- Max clip length per job: up to 10 minutes
- Processing speed: approximately 10–30 seconds of wall time to process 1 second of video (varies by resolution and queue load)
How to Use
- Choose target resolution — select 720p, 1080p, 2K, or 4K based on your needs.
- Upload your video — drag-and-drop or paste a public URL (≤ 10 minutes).
- Submit — run the job and wait for processing.
- Download — preview and save the upscaled result.
Pricing
Per-second billing with a 5-second minimum. The table below lists prices per 5 seconds for easy comparison.
| Output Resolution | Cost per 5 seconds |
|---|---|
| 720p | $0.10 |
| 1080p | $0.15 |
| 2K | $0.25 |
| 4K | $0.40 |
Billing Rules
- Minimum charge: 5 seconds
- Per-second rate = (price per 5 seconds) ÷ 5
- Billed duration = video length in seconds (rounded up), with a 5-second minimum
- Total cost = billed duration × per-second rate (by output resolution)
Pro Tips
- Upload the highest-quality source you have; avoid heavily compressed inputs when possible.
- Keep original frame rate; avoid unnecessary re-encoding before upload.
- Pick the lowest resolution that meets your delivery needs (1080p = speed/cost, 2K/4K = maximum detail).
- For long videos, process in segments to parallelize and then merge.
Notes
- Video is the only required field.
- Maximum video length per job: 10 minutes.
- Ensure video URLs are publicly accessible.
