I am trying to create a batch processor to increase the length of a video using framedump. I have an 11.2 second (6720 via getduration) video and I want it to be 15 seconds (assumedly 9000 in QT time... 6720/600=11.2, so 15*600 = 9000). To output the new video and get the appropriate length, I need to produce a new FPS, which is passed via my write statment. I though 6720/224=30 so 9000/224 should render my new FPS, but no dice. Totally sticking on this one, I appreciate any insite.
