Playback lag/ export issues
I am rather new to video editing, but I have been having some issues with video playback and exporting. My video camera records videos in MTS. I use handbrake to transcode to an MP4. But when I import it to hitfilm, it lags to the point where I can't do anything with it. I have tried other suggestions like converting it to the Go pro cineform file within hitfilm, but when I export it as an MP4, it is stretched terribly. I have also tried changing the codec to an MPEG4. This helps a little but it is still laggy. I have heard about using intermediate codecs for editing such as DNxHD, but I cannot find anything about how to convert to these files. Any help would be appreciated!
