If you get the USB Dongle license version you can also use Fusion, the separate Video FX suite. Also if you need to work with interlaced video, for example editing old SD PAL/NTSC videos, you need the studio version for proper interlacing handling. If you need to work with interlaced material, noise reduction and all possible video effects, then you need this paid version. Unfortunately, even with this paid version, there are encoder and decoder limitations under Linux. Updates from major and minor versions have been free so far.

This version requires a license, either a registration code (allows two installations) or a USB license dongle (that must be connected at all times). Studio version - Relatively cheap (~300€) version that has no limitations, all features are available.Does not utilize a GPU as much as the paid Studio version. For many uses and users this version does pretty much everything you might need for video editing. It has some limitations on used export resolutions, available plugins and some of the more advanced features (noise reduction, effects, audio and video encoders/decoders, interlaced video handling, GPU usage). Free version - Free to download and use.There are two versions available of Blackmagic Design DaVinci Resolve, the free version and the paid studio version:
