FAQ
How long does it take to upscale a video?
Most short clips finish in a few minutes. Longer duration, higher input resolution, and 4× scale take longer because every frame is enhanced.
What video formats do you support?
MP4, MOV, and M4V. Upload clips up to 720p on the longer edge, within the size and length limits on this page.
Is the video upscaler free?
New accounts get 5 welcome credits. Each upscale uses credits based on resolution, duration, and scale. Credits are one-time packs — no subscription.
Will the enhanced video retain its original quality?
AI upscaling improves resolution and perceived sharpness. It cannot invent true optical detail that was never captured, but it avoids simple blurry stretch.
Is my video data secure?
Uploads are processed for your request and are not used as a public gallery. Do not upload confidential footage you are not allowed to process.
Can I upscale old or vintage videos?
Yes — short digitized home videos and vintage clips are a common use case. Results vary with compression, shake, and original resolution.
