How-to knowledge guides
- How to upscale video to 4K with AI, not plasticA practical guide to AI video upscaling: what it can recover, where it falls short, and how to get sharp results from 480p or 720p source footage.
- How to restore old video with AI — grain and colorStep-by-step guide to AI-powered old video restoration: removing grain, fixing color fading, and recovering detail from vintage or damaged footage.
- AI Smart Cutout for video — no green screen requiredHow AI-powered video cutout isolates subjects frame by frame for compositing, background replacement, and clean cutouts — without studio setup.
- How to upscale Sora, Kling, and Veo videos locallyAI generators deliver striking clips at modest resolutions. Why generated footage looks soft, which models fit which style, and a local workflow that scales to batches.
- How to fix blurry or pixelated video with AIFive ways to fix blurry, soft, or pixelated video — from free sharpening to local AI unblur — and how to pick the right method.
- How to denoise video with AI without plastic facesWhen grain is signal, which sources respond, and how to preview locally before a full export.
- How to stabilize shaky video with AI (and when crop hurts)Strength vs crop, rolling shutter caveats, and local preview before you export.
- Convert video formats locally without uploadsDeliver masters locally after enhancement — codecs, containers, and why a built-in converter matters.
- How to remove background noise from video — locallyViewers forgive soft pixels before they forgive hissy dialogue. Denoise, cut room echo, and separate vocals in the same local pipeline as the picture — no extract-then-reimport.
- SDR to HDR and AI frame interpolation — enhance without another upscaleAlready 1080p but still washed out or choppy? SDR-to-HDR, AI Color Enhance, 2x/4x interpolation, and up to 8x slow-mo run locally — preview before you export.
- Replace a video background without opening a compositorPerson replace combines AI cutout with a new plate in one local step — solid, still, or video backgrounds — when you do not need a full After Effects graph.
- How to replace an object in video with local AISAM2 click-to-track lets you mark a prop or vehicle and swap its plate — transparent, solid, gallery, or blur — without uploading the clip.
- How to replace a sky in video without a rotoscope graphSky Replace is a dedicated local workbench for dull or blown-out skies. Preview the horizon on a pan before you export.
- How to remove an object from video — locally, not in the cloudDynamic Tracking Removal follows a walker or car. Static Removal stamps parked clutter. Both are object-erase workbenches — not watermark marketing.
- How to repair a corrupted video file that will not playVideo File Repair diagnoses unplayable MP4s locally. Auto, Quick, Deep, and Smart modes — plus an optional same-camera reference. Not an enhancer.
- How to edit video subtitles locally — SRT/ASS, not translationSubtitle Edit is the shipped local workbench for SRT/ASS cues: style, timing, burn-in or MKV soft-sub. Translation and speech-to-subtitle are not in this release.
- How to enhance photos locally — repair, 4K, and cutoutFive image-repair types (1x up to 4K), portrait cutout, object cutout/removal, and folder batches — on your GPU, no upload. Previews are free without an account; export needs a paid plan.
- 480p to 4K: what AI can recover — and what it cannotA 4K file from 480p will look better than a player stretch. It will not equal a native 4K camera. Here is what reconstructs, what only cleans up, and what is gone.
- Four upscaling models: general, portrait, anime, nightOne super-res button is four priors. General, portrait, anime, and night-scene each fail in a different way if you pick the wrong one.
- What file repair actually does when a video will not openUnplayable is a container problem, not a quality problem. Diagnosis, then Quick / Deep / Smart — optional same-camera reference. Not an enhancer.
