Did you shoot 30p or 30pN?.... In 30p, I believe you have to remove the redundant frames.

In order to actually shoot 2 times slow motion to the cards you have to shoot 24pN or 30pN, then from there you set you Variable Frame Rate to 60p....If you shoot in 24p or 30p, you're going to be shooting two (for 30p) sets of each frame or 2.5 (for 24p) of each frame. In order to do that, you have to remove the frame rates in post. That's the difference between pN and just p...... pN records exactly the amount of frames you shoot. p records 60p reguardless of what frame rate you choose to shoot at.....
If you shot 30p with a double over crank at 60p, then you're looking at 60p @ 30p over 60p. So you're getting 2:1 and then recording two times the choosen frame rate because the camera records at 60p no matter what, unless you're using pN(ative). So you're final frame rate comparision is 2 (over-crank):1(frame rate):2 (recording speed). What you have to do is get that 2 at the recording speed to 1. So you need to remove the redundant Frame Rates. I thought importing into a 30p timeline automatically took care of that.

And to double check, you are shooting 720p right? Not 1080.


For a better explaination, look at the following website:

I have to say, I personally don't own this camera. Actually, never touched one. I want to, just can't afford it. However, you'll find that the information above, is backed up by the things said in that website.

Andrew is correct.....
Plus if you change to speed and then turn the camera
off it will go back to the default setting.
You can save the scene file if you need
to keep shooting at 60 fps.....

thanks everyone a ton. so i won't see the the 60p until i take it to post? i thought the images would be in slowmo during the playback in the camera, much like the timelapses when shot with "Interval" mode.

i don't understand how to take out the frames while editing in post to achieve the slowmotion. before i had this camera to slowmo i just went to "speed" and chose a percentage. according to the manual for hvx200, the higher frame rates should give you an image on playback in the camera; i don't see this when in the field nor do i see it when i bring it to post.

rggggggh.
a little more help please? i will go check the website posted earlier in this thread.

If you shoot on the cards, you will see the effect immediately. If you shoot on the firestore, no -- you have to process it in post. Version 3.0 of the firestore firmware should rectify that.

But if he shoots 30p and not 30pN he wouldn't see it from the cards either right?

That is correct, you'd have to shoot 30pN to see the effect. If you shoot 30P you can run the Apple Frame Rate Converter to extract the duplicate frames in post, but you can't see the effect in-camera from 720/30P mode. You'd have to use 30pN (or 24pN).
