Ignite Pro is a collection of over 150 HitFilm effects which can be installed as plugins into third party video editing software. So if you wish to access HitFilm effects outside of HitFilm, Ignite Pro is available separately and will allow you to install many HitFilm effects directly into your editor of choice. You can also get both HitFilm Pro and Ignite Pro bundled together, in HitFilm Studio.
The plugins mean that you can choose how, where and when you work with HitFilm technology. If you want to use the effects inside of HitFilm, Ignite is not required, but if you have a third party editor that you are already comfortable with, Ignite allows you to access HitFilm effects directly inside of that software.
Current compatible hosts include:
The plugins are a subset of HitFilm Pro's effects and they function in very similar ways. Some host platforms have limitations compared to using the effect directly inside HitFilm Pro - for example, Premiere Pro cannot use effects which include a layer picker and only After Effects includes a 3D camera similar to HitFilm's. Due to these limitations, the exact number of Ignite effects available within each host program will vary.
Details on specific effects can be found in the Visual effects section.
