I am working with Premiere CS6. in my CS6-Projekt I have imported an AVCDH-Clip from my Panasonic HDC-TM700. A AVCHD-Clip from a Canon Camera, I had stabilized an Color corrected and new renderd to a H.264, HD1080i25.mp4 and also imported to my Projekt. When i take this Clips to my Timline, i have red and green Frames on my Panasonic Original AVCHD-File. When i have rendered this File i also have red an green Frames in the new File.
Why export a sequence as a file and then re-import it? You can always add an existing sequence into a new sequence (nesting) to make a new less cluttered way of working. Does this way still make red and green frames?
