Green screening reduces your roto to Hue/RGB keying. Anything else - a greenscreen and/or mocha, or high res AI roto - is going to cost money. If money is tight, the free AI roto (with low res masks) can save a lot of time. masking in Hitfilm is the hardest and most tedious. Free versions generally spit out low-res (standard def) masks, but, depending on what you're doing, there are some ways to tweak the generated masks.Īll that said, no matter what, manual roto is tedious and boring and time consuming. There are AI tools emerging that will automatically roto humans. Mocha can reduce manual roto time but 75% or more. Mocha is billed by Imagineer as your 'roto assistant.' Mocha can try to track your overlapping shapes and deform with them. Masks are allowed to overlap, so your neck/shoulder mask (the one with the least movement) can overlap the face.įor rotoing yourself - well, can you get a pop-up green/blue screen or have access to a wall you can make a solid, contrasting color? Chroma key is all about avoiding roto. For the video you've shown, this is three masks - one for the neck and shoulders, one for your face shape (which will deform more with facial expressions) and one for hair.

General mask-roto tip: Break the object into pieces instead of masking everything as a single shape. Each format also includes its own options for presets which use that format. There are a number of different formats available for export, each optimized for a specific purpose or application. Using the mask tool from by frame is the typical method. HitFilm gives you full control over the settings used when exporting. Ok, so, in general the frame by frame masking (rotoscoping) is a common technique.
