# Improve Video Quality > To improve video quality, record in good light at your camera's highest resolution, export at a high bitrate without re-encoding, and enhance video quality with AI when you can't reshoot. Kenerate's AI Video Upscaler turns low quality video into high quality at 1080p, 2K or 4K, removing compression blocks while keeping the length and frame rate.

Drafts, previews and messaging. - 1080p · Popular (AI Video Upscaler): Video up to 5 min / ~100 MB → Pixels of 1920 × 1080, shape kept. YouTube, Instagram, TikTok and the web. - 2K · Sharp (AI Video Upscaler): Video up to 5 min / ~100 MB → Pixels of 2560 × 1440, shape kept. Desktop viewing and cropping room. - 4K · Max (AI Video Upscaler): Video up to 5 min / ~100 MB → Pixels of 3840 × 2160, shape kept. TVs, projectors and 4K uploads. ## Steps 1. Fix what you still can — If you have the project, re-export at a higher bitrate — AI works best on the cleanest copy. 2. Upload to the AI Video Upscaler — MP4, MOV or WebM, up to 5 minutes and about 100 MB. 3. Pick the target — 1080p for phones and social, 2K for monitors, 4K for TVs. 4. Check and download — Compare in the before/after viewer, then download the MP4 — no watermark. ## In depth ### Resolution, bitrate and noise are different problems Resolution is how many pixels each frame has. Bitrate is how much data per second describes them, so a high-resolution file at a low bitrate can look worse than a clean smaller one [1]. Noise is random grain, worst from small sensors in low light [2]. Each needs a different fix. ### Why low light ruins phone video In dim light a small sensor gathers little signal, the camera amplifies it, and noise rises with it [2]. The encoder then spends its bits describing that noise instead of detail. Adding light is the single biggest quality upgrade you can make. ### Where AI enhancement fits When you can't reshoot, video super-resolution rebuilds detail from neighbouring frames [3], and Kenerate's upscaler also removes compression blocking and banding. It has no denoise slider and doesn't change the frame rate or stabilise — do those in your editor.

A: Improve it at the source when you can — better light, locked focus and the highest resolution setting — and export once at a high bitrate. For an existing clip, upload it to an AI video enhancer such as Kenerate's AI Video Upscaler and choose 1080p, 2K or 4K to rebuild cleaner detail. Q: How do I turn a low quality video into high quality? A: Upload the low quality video to an AI upscaler and choose a higher output size. Kenerate's rebuilds each frame at 720p, 1080p, 2K or 4K using detail from neighbouring frames, removes compression blocks, and keeps the aspect ratio, length and frame rate of the original. Q: Can you enhance video quality without losing detail? A: Yes, if you avoid extra encoding passes. Upload the original file once, upscale it once to the final size and download the MP4. Each re-export of a re-export adds compression loss, which is why the first step is always finding the cleanest copy you have. Q: Does a higher resolution always mean better quality? A: No. A 4K file with a starved bitrate or heavy noise can look worse than a clean 1080p one. Resolution is only one part of quality; bitrate, light and focus matter as much. AI upscaling raises resolution and cleans compression, but it can't fix poor lighting. Q: Can AI improve the quality of an old video? A: Yes, once it is a digital file. Kenerate upscales digitised clips — old phone videos, camcorder transfers, captured tapes — to 1080p, 2K or 4K and removes compression blocking. Tapes have to be captured first; the VHS restoration guide explains how. Q: How long does it take to enhance video quality? A: A few minutes for a short clip; 4K and longer clips take much longer, so trim the video to the part you need before uploading. Clips can be up to 5 minutes and about 100 MB, and if a job fails its credits are refunded automatically. Q: Is there a free way to improve video quality? A: Better light, a clean lens and a higher-bitrate export cost nothing. For AI enhancement on Kenerate, new accounts get starter credits to try it on their own footage; after that you pay per second of clip with credits, with no subscription required and no watermark. ## Related pages - AI video upscaler: https://kenerateai.com/ai-video-upscaler - How to fix pixelated video: https://kenerateai.com/how-to-fix-pixelated-video - Unblur video: https://kenerateai.com/unblur-video - Upscale video to 4K: https://kenerateai.com/upscale-video-to-4k - VHS restoration: https://kenerateai.com/vhs-restoration ## Sources - Kenerate AI Video Upscaler (tool): https://kenerateai.com/app/tool/video-upscale - Bit rate — Wikipedia: https://en.wikipedia.org/wiki/Bit_rate - Image noise — Wikipedia: https://en.wikipedia.org/wiki/Image_noise - Video super-resolution — Wikipedia: https://en.wikipedia.org/wiki/Video_super-resolution
