The ability to record in log is very important. Without log, you're never going to get the results as advertised on the box. You can attempt to grade any footage from any camera with any color grade software, but with a huge amount of limitations. When recording in a format that is not "log", you will have already trashed the majority of data an app like this needs to make those subtle adjustments. In log, the highlights tend to be preserved better as well as details in shadows have not be crushed into oblivion. If your non-log footage is brought in, the same knobs/buttons will be available, but the data it is needing has been lost and it just will not have the same effect. You will not be satisfied with "its abilities" as you are now in the "you're doing it wrong" with your workflow
