§02By category
Grouped the way the app is.
Quality Enhancement, AI Beauty, AI Color Grading, the AI Toolbox, and the Converter, Repairer and Downloader: the same groups you'll find in the app's sidebar.
AI Beauty
AI Beauty built for video
Retouch, skin, makeup, facial features, face shape and hair color, designed to stay steady through motion.
AI Color Grading
Color, from SDR to HDR
SDR to HDR, Smart Color for casts and flat tones, and Filter Grading you can fine-tune.
AI Toolbox
Cut, replace, remove, steady
Cut people out without a green screen, swap skies and backgrounds, remove objects, stabilize, add effects, clean up voices and edit subtitles.
Converter · Compressor · Repairer · Downloader
Convert, repair, download
Batch-convert video, audio and images, make GIFs, convert DVD titles, repair files that won't open, and download a file from a link.
§03One pass
Deinterlace, repair, upscale, interpolate. In one pass.
In Quality Enhancement these steps stack in a single run: no exporting and re-importing in between, and one less round of compression.

Example: a 1080i camcorder wedding tape, exported once as 4K at 50 fps.8K output needs H.265 or AV1.
§04Batch
Load a batch, export them all.
Load several clips or photos into one workspace, set the parameters on one, use Apply params to others, then Export all. Each item goes to Task Center, where you can follow its progress. Preview your hardest clip first.

What it won't do, written down.
Better to know the limits before you buy. You can check each one with the free preview.
Detail
It can't recover what was never captured
Heavily degraded 480p footage gets clearly better, not native 4K.
Motion
Heavy motion blur is the hardest case
Blur from low resolution and compression responds well; motion streaks only partly.
Stabilization
Stabilizing crops the edges
The more shake, the more crop. Use Subject Lock when the subject has to stay put.
Audio
Vocal separation depends on the mix
Dense productions separate less cleanly than a single voice.
Speed
Speed depends on your computer
There's no cloud acceleration. Integrated graphics work, but 4K, long clips and stacked effects take longer.
Subtitles
Subtitle Edit isn't speech-to-text
It edits SRT and ASS subtitles and burns them in, or adds them as soft subtitles in MKV. It doesn't transcribe or translate.
