I am try to import some files to Hitfilm 3 Express the error I encountered was that the file are not compatible with hitfilm 3 express. The file is an MOV type video file and I have imported same file before in the time past.
I have had that problem to, the best fix I found was converting them to mp4 files with a converter. The one I have been using is called Handbrake it's really good once you learn how to use it.
Convert the video files to .mp4 format, and then import.I use Aiseesoft Video Converter Ultimate, it maintains the quality and it really works well.If you cannot afford to buy Aiseesoft Video Converter Ultimate, you can try Format Factory which is freeware.Hope that helps.
If you are having trouble importing Quicktime files (.mov), then most likely your installation of Quicktime is either out of date or missing. Make sure you have the latest Quicktime installed, restart your computer, and you will be good to go.
And uninstall HitFilm and then reinstall Hitfilm and see if that works
I have this fixed, I downloaded and install quick time on my computer and Hitfilm was able to work with files. Thanks everyone for your input.
