Gday I was wondering what could be the most efficient method to slow down a movie. I have here some Super 8mm material that I reshoot frame by frame in ppm files.
The original are playing at a nominal rate of 18 fps. Once encoded in mpeg2, grany is almost running through the TV screen. I thought that pulldown would be an option to bring 18 to 24 but obviously not since mpeg2enc is complaining about the rate Is ther a way I can go around that ? ++ WARN: [mpeg2enc] 3:2 movie pulldown with frame rate set to decode rate not display rate ++ WARN: [mpeg2enc] 3:2 Setting frame rate code to display rate = 5 (30.000fps) INFO: [mpeg2enc] Encoding MPEG-2 video to test_pulldown2.mpeg INFO: [mpeg2enc] Horizontal size: 720 pel INFO: [mpeg2enc] Vertical size: 576 pel INFO: [mpeg2enc] Aspect ratio code: 1 = 1:1 pixels INFO: [mpeg2enc] Frame rate code: 5 = 30.0++ WARN: [mpeg2enc] 3:2 movie pulldown with frame rate set to decode rate not di splay rate ++ WARN: [mpeg2enc] 3:2 Setting frame rate code to display rate = 5 (30.000 fps) INFO: [mpeg2enc] Encoding MPEG-2 video to test_pulldown2.mpeg INFO: [mpeg2enc] Horizontal size: 720 pel INFO: [mpeg2enc] Vertical size: 576 pel INFO: [mpeg2enc] Aspect ratio code: 1 = 1:1 pixels INFO: [mpeg2enc] Frame rate code: 5 = 30.0 INFO: [mpeg2enc] Bitrate: 7500 KBit/s INFO: [mpeg2enc] Quality factor: 8 (Quantisation = 9) (1=best, 31=worst) INFO: [mpeg2enc] Field order for input: none/progressive INFO: [mpeg2enc] Sequence unlimited length INFO: [mpeg2enc] Search radius: 16 INFO: [mpeg2enc] GOP SIZE RANGE 6 TO 15 INFO: [mpeg2enc] Setting colour/gamma parameters to "unspecified" INFO: [mpeg2enc] Progressive format frames = 1 INFO: [mpeg2enc] 3:2 Pulldown selected frame decode rate = 24.000 fps **ERROR: [mpeg2enc] Sample rate is greater than permitted in specified Level INFO: [mpeg2enc] Bitrate: 7500 KBit/s INFO: [mpeg2enc] Quality factor: 8 (Quantisation = 9) (1=best, 31=worst) INFO: [mpeg2enc] Field order for input: none/progressive INFO: [mpeg2enc] Sequence unlimited length INFO: [mpeg2enc] Search radius: 16 INFO: [mpeg2enc] GOP SIZE RANGE 6 TO 15 INFO: [mpeg2enc] Setting colour/gamma parameters to "unspecified" INFO: [mpeg2enc] Progressive format frames = 1 INFO: [mpeg2enc] 3:2 Pulldown selected frame decode rate = 24.000 fps **ERROR: [mpeg2enc] Sample rate is greater than permitted in specified Level here is the line I am using cat *.ppm | ppmtoy4m -F 18000:1000 -L | y4mscaler -I sar=1:1 -O size=720x576 -O chromass=420_MPEG2 -O sar=PAL | yuvdenoise -b 20,20,680,536 -r 16 -t 2 -c 80 -F -L 160 | mpeg2enc -r 16 -I 0 -B 96 -g 6 -G 15 -a 1 -H -4 2 -2 1 -F 2 -f 8 -M 2 -p -o test_pulldown.mpeg Or either using yuvfps ?
