Slow Motion on HVX200
Greetings one and all, I am trying to shoot slow motion on the Panasonic P2.
I am using a Firestore Hardrive, I set the camera to 720 X480 / 30P, and put the frame rate at 60P, thinking this would work but it does not.I was being told to put the camera on 720X480 PN, but when I do that the camera will not record. Can someone help me with this. I’m not sure if it is because I’m not using the P2 Card, and maybe the portable drive does not work this way.

Upgrade your FireStore’s software to version 4.0. That enables slow-mo recording. Be sure to read the documentation thoroughly so you get the proper settings right.

Thanks Barry, I think we are pretty updated. The drive came without software, but i will search on their website to download the latest plugin if available.
Thanks again for your help, I f I get it working I will surely let you know.

Hi,
720 X 480/30P is a standard definition format. Look for 720P/24PN or 720P/30PN on the menu. Set your camera to 720P/24 not 24PN and be sure that the User Bits are in Frame Rate. If you have the 3.0 version, this should do it for you.
When you are finished, do not fail to P2 Organize on the Firestore or you will have a soup of little clips and it will be a big mess.
Hope this helps,

Jan, I just read your message about the 720/24p vs 720/24pn as it relates to shooting slow motion or any variable frame rate for that matter. As far as I know from my own testing and other docs I’ve read, you have to be in 720/24PN or 30PN mode in order to achieve the variable frame ability of the camera. This contradicts what you’ve written here. I’m not sure if I read your message incorrectly, or maybe there is some loop hole I’m unaware of with the camera’s ability to over or under crank. I’m not trying to be confrontational by any means, I just want to clarify my own findings to make sure I’ve got it right in my head as to what the camera is doing. Could you comment on this for me when you have a chance.
Cheers,

Hi,
Within the HVX200, if it were set to 24PN, nothing would come out of the Firewire port. If you are trying to record this onto the Firestore drive you have to have the data coming out of the port and into the Firestore. What will come out is all 60 frames and you have the firestore set properly so it will strip out all of the duplicate fames. the firestore is set to 24PN.
Obviously you have not tested the 720P/24P thoroughly as you most definitely can shoot off-speed footage with the HVX200 in that mode, it embeds into a 60 frame stream, just as if it were a Varicam. You would then have to use a frame rate converter to get the frames out of there.
Now the last and most critical is that in your USER BITS setting you need to be sure that it is in FRAME RATE. If not the Firestore will no know which frames to throw away.
Best,
Jan

Hmmm. That’s curious. Thank you for your speedy response. I don’t know much about using the fire store because I’m at the post end of things and I don’t get a lot of opportunity to test these things out. However, when I did test slow motion, set at 60fps 720/24p, the camera wouldn’t actually record in slow motion. When I viewed the playback in camera from the P2 cards it looked normal and played back at normal speed. I then decided to check the camera manual and found out that the camera, according to the manual, has to be in either 720/30pn or 24pn in order to perform an affective variable frame rate. So, I don’t really understand how you were able to capture slow motion, 60fps for sake of argument, in the 720/24p mode. I know the camera will allow you to change the frame rate when you’re not in native mode but I didn’t see any change in speed. Maybe it has something to do with going to the P2 card vs. the firestore. I don’t know. Anyway the reason why I’m persisting with this is because I’m a post coordinator for a small group of editors and we just went through a shoot where the DP claimed he shot 60fps to achieve slow motion to the P2 cards. However, when I ingested the footage it did not play back in slow motion. Weird. So I was wondering if you might know why? I know the DP shot everything 720/30p which makes sense because everything imported as 29.97. Then when he went to do the slow mo shot I think he only changed the frame rate to 60fps and forgot the mode change to 720/30pn. That’s my guess anyway, so what do you think? The other clue also is that the clip came in with audio recorded by the on-board mic which apparently is impossible, the camera will not record sound in variable frame rates. So, I would love to know what you think, because if there is a way we can convert the clip somehow to regain the slow motion effect that would be super. Thanks again for your help.

Jan,
Please excuse me, I’m still learning these systems. I actually should have kept reading the manual and would have found that it talks about shooting VFR in 720/24p. So, my apologies I just didn’t read it carefully enough in my haste to test it, I only had about 15 minutes with the camera, so I had to be fast. Anywho, it talks about doing a frame extraction so I’m guessing that’s all I have to do to view the footage supposedly shot at 60fps in slow motion. Is there a good or bad way to do this extraction? Do I need specific software or will FCP 5.1.4 handle it through Cinema Tools or Media Manager? How would you recommend going about it?
Thanks again for all your help and patience I really appreciate it.
Cheers,
James
