Bytedance Video Upscaler

Bytedance Video Upscaler

Playground

Video Upscaler uses AI super-resolution to upscale videos to 4K and recover fine detail in a secure cloud environment. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

BytePlus VOD’s enhancement feature provides an intelligent and efficient solution for improving video quality through AI algorithms. This feature integrate atomic capabilities like face enhancement, color enhancement, text enhancement, compression distortion removal, noise reduction, deblurring, dark scene optimization, and brightness equalization. It adaptively matches the optimal processing strategy to ensure that videos present a clearer and more vivid visual effect at the same bitrate.

Powered by a high-quality, large-scale training dataset covering both OGC (Professionally Produced Content) and PUGC (Professional User-Generated Content).

What Seedance does

• Super-resolution upscaling to 1080p / 2K / 4K with detail recovery and de-ringing
• Temporal consistency to reduce flicker and ghosting between frames
• Works well on live-action, animation, game captures, product reels, and vertical shorts

Inputs

• video – The source clip you want to enhance.

• target_resolution – One of:

• 1080p

• 2k

• 4k

How to use

1. Upload or paste the URL of your video.
2. Choose the desired target_resolution (1080p, 2k, or 4k).
3. Click Run to upscale; then compare the result with your original in your editor or viewer.

Notes

• Very short clips are billed with a 5-second minimum.
• Jobs longer than 600 seconds (10 minutes) only bill the first 600 seconds.

Pricing

• Minimum charge: 5 seconds at the chosen resolution
• Maximum billed duration: 600 seconds per job

Tips

• Feed the highest-quality source you have; upscalers can’t fully restore detail from heavy blur.
• If the source is very noisy, denoise first, then upscale.
• Match your export’s aspect ratio to the target platform to avoid letterboxing after upscaling.
