Do NOT switch your camera to ntsc. Shoot at 720p50 if you're shooting a PAL project, in SH mode. I would have thought you'd be shooting in manual movie mode so you can control shutter speed and aperture yourself.

?? He said he wanted his slow motion to be a slow as possible, which means making the camera record at as high a frame rate as possible. 720/60p is the GH2's highest frame rate mode. Though shooting in 60p means he loses the flexibility to keep the footage at normal speed.

@balazer -Sounds right - no NTSC-PAL pulldown going on.

-Or, try using FFmpeg:

The only thing you have to do for the video is to change the metadata of your clip. The audio will have to be played slower too, so will sound lower. If you want to fix this, you have to pitch this up (with audacity or sox).

How to do this with ffmpeg? Well, in two steps:

• extract the frames as rawvideo

  ffmpeg -i input.mov -f rawvideo -b 50000000 -pix_fmt

  yuv420p -vcodec rawvideo -s 1920x1080 -y temp.raw

• recreate the video with new framerate

  ffmpeg -f rawvideo -b 50000000 -pix_fmt yuv420p -r 24 -s

  1920x1080 -i temp.raw -y output.mov

• To save on needed intermediate disk space, you could send the output of the first to stdout and pipe it to the input of the second

50 fps to 25 fps is a 2x slowdown. 60 fps to 25 fps is a 2.4x slowdown. It's 20% more, if that makes a difference to you. Shooting 50 fps means you retain the ability to play the footage at normal speed in 25p just by dropping every other frame. You lose that ability if you shoot 60p, though there are imperfect ways to convert between frame rates by blending or interpolating frames.

mozes, you must have done something wrong, as the extra frames of 60p won't be lost if you do it correctly. I know how to do it in Vegas and AviSynth.

SH mode is a higher bit rate than H mode. http://www.personal-view.com/faqs/gh2-usage/gh2-usage
