In Multicam Logger, you can record the different camera ISOs with MovieRecorder or with any other recording device, including recording on the camera itself. However, you will be limited in some file types and codecs.
Install QuickTime components
Unlike all of our recent applications which do not use the QuickTime APIs anymore, Multicam Logger still uses the QuickTime APIs to read the video files and get the required info out of them (TC, format, duration, etc.).
So the type of file that is supported by Multicam Logger depends on which QuickTime component is installed on your Mac. You can easily verify if your file will be supported or not by downloading QuickTime 7: https://support.apple.com/kb/DL761?viewlocale=en_US&locale=en_US
If you can open the file with QuickTime 7, we should be able to support it, if you can't open the file with QuickTime 7, then for sure Multicam Logger will not support it.
Note that it is possible to install additional components to support more codecs. For more information about this, please check this article: https://softron.zendesk.com/hc/en-us/articles/207697917-About-the-support-of-QuickTime-codecs-in-applications-using-the-QuickTime-APIs
