Video Upscaler uses AI to increase the resolution of any video file — sharpening detail, reducing compression artefacts, and improving overall clarity. You can upscale footage to 720p, 1080p, 2K, or 4K. The tool processes your video frame by frame, so the result is a significantly improved version of the original without re-shooting.Documentation Index

Upload your video
Drag and drop a video file onto the upload zone, or click the zone to browse your files. The upscaler accepts any common video format (MP4, MOV, WebM) up to 500 MB and 10 minutes in length.
Once you select a file, a preview player appears so you can verify the correct clip before processing.
Choose a target resolution
Use the resolution dropdown in the control bar to select your output:
The estimated credit cost for your specific video is calculated automatically and shown next to the Upscale button.
| Resolution | Credit cost |
|---|---|
| 720p | 60 credits / second |
| 1080p | 90 credits / second |
| 2K | 150 credits / second |
| 4K | 240 credits / second |
Review the credit estimate
After the video loads, Artnex reads its duration and displays the total estimated credit cost based on the resolution you selected. Confirm this looks correct before proceeding.
Start upscaling
Click Upscale. Artnex first uploads your file to secure storage, then passes it to the AI upscaling pipeline. A progress bar tracks both the upload and the upscaling stages.
Upscaling time depends on the video length and the target resolution. A 1-minute clip at 4K typically takes 3–8 minutes to process.
Credit costs
Credits are charged per second of video at the rate for the selected resolution. There is no flat per-job fee.| Resolution | Credits per second | Example: 30-second video |
|---|---|---|
| 720p | 60 credits/sec | 1,800 credits |
| 1080p | 90 credits/sec | 2,700 credits |
| 2K | 150 credits/sec | 4,500 credits |
| 4K | 240 credits/sec | 7,200 credits |
The credit estimate shown in the UI is based on the video’s detected duration. If the duration cannot be read before upload, the estimate defaults to 5 seconds until the actual duration is confirmed.
