What is an AI video upscaler?

An AI video upscaler uses artificial intelligence to increase the resolution of a video while maintaining or improving quality. Unlike simple interpolation, AI upscaling predicts and generates missing detail frame by frame, with temporal awareness to prevent flickering.

Is this video upscaler free?

Generation requires credits from a paid plan. Each video upscale costs credits based on the video length, resolution, and model used. Paid plans offer more credits.

What scale factors are available?

Melies supports 2x and 4x video upscaling. A 720p video becomes 1440p at 2x or 2880p at 4x. Both factors produce smooth, artifact-free results with consistent frame quality.

Will upscaling add flickering or artifacts?

No. The AI models are specifically designed for video with temporal consistency. Each frame is enhanced while maintaining smooth transitions with neighboring frames, preventing the flickering common in naive upscaling approaches.

Can I upscale AI-generated videos?

Yes. The upscaler handles AI-generated video, real footage, screen recordings, and animations equally well. It's particularly effective for AI-generated clips that often output at lower resolutions.

What file formats are supported?

Upload MP4, MOV, or WebM videos up to 100MB. Output is delivered as high-quality MP4 for maximum compatibility.

Which model should I choose?

Topaz Video offers the best sharpness for professional output. SeedVR2 Video provides the best quality with temporal consistency. FlashVSR is fastest and cheapest, great for quick previews. Try multiple models on a short clip to compare.

Can I use upscaled videos commercially?

Yes. All videos processed on Melies are yours to use commercially. No watermarks, no attribution required.

Upscaling can create detail that was not present in the source. Review faces, text, edges, grain, and fast motion before using the output in a final master.

What the workflow does

01
Upload the source
Choose a short video and inspect its native dimensions, motion, grain, and compression before selecting an upscale factor.
02
Choose a model and scale
Use 2x for a conservative enlargement or 4x when the delivery target requires it. Model availability and exact cost are shown in the authenticated tool.
03
Review the complete output
Check faces, lettering, edges, texture, and fast motion at full size. Keep the source when generated detail does not hold up.

Review before delivery

Output: High-resolution MP4 with the source soundtrack retained when the input contains audio.
Best sources: Clean, stable footage with enough original information for the selected model to interpret.
Watch for: Invented facial detail, altered text, edge shimmer, oversharpening, and temporal inconsistency.
Long projects: Use Long Film Upscaler for scene selection, chunked processing, retry, resume, and final-film rebuild.
Pricing: The authenticated tool calculates the current credit estimate from the selected model, scale, and source.
