24p questions

Stephen van Vuuren · January 2nd, 2004, 12:51 PM

For good slo mo, you need more frames per second than normal, not less.

That's why there are specialized film cameras that shoot hundreds of frames per second (think slow mo bullet shots etc.).

DVX100 maximum is 30fps progressive, and 60fps interlaced.

I don't think you can, can you? I don't think the 24P modes work with time lapse, because of the pulldown issues. You'd have to use 30P or 60i for time lapse.

And yes, regardless, speeding up the time lapse footage will be quite smooth.

Mike Zorger · January 2nd, 2004, 01:38 PM

no, im not saying use the tap laps feature on the camera. But just let it record, and make a time laps. Would it blur up and not look smooth if you put the speed % up high from 1000-4000 depending on how long it is and how fast you want the time laps to move.

If you shoot normal footage and then speed it up, it will not blur, just give you very fast footage. All that happens when you speed up footage is that it starts to skip frames. IF you are running ntsc regualr 30fps and decide to speed that up, say 200%, you would basically be playing 2 seconds worth of footage in one second. 15 frames from the first second, and 15 from the 2nd second. The more you speed up your footage, the fewer original frames you will be keeping. This can give you smooth footage if you kept the camera steady for a very long time, however, I don't think this is what you are looking to do. Time laps does not slow down motion it speeds it up dramatically.

Barry Green - FWIW - I found that disabling resampling in Vegas makes slowing 24p almost acceptable. That being said, 30p is def. better.

Barry and/or anyone else who's used 60i for slo-mo in a 24p timeline: I've just shot some 60i footage for a slo-mo effect in a 24p movie. Haven't yet digitized it, since I'm on location. How specifically will this work in FCP, if cutting in a 24p timeline? Any issues with importing the 60i footage into a 24p timeline? Thanks for any info.

I don't use FCP so I'll have to defer to someone with more expertise on that. In Vegas it's really simple, you import the clip into a 24P timeline, and tell it to use a playback rate of 40%, and that's about all you have to do! Make sure your de-interlacing/blending fields options are set to the best quality as well.

I have shot tons of time lappes and they turn out TIGHT. I bet i have shot better Time lapes than 90% of the people on this site.
Peace

Mike Zorger · January 12th, 2004, 08:10 AM

I know this may have been asked in the past, but how do i save my settings when i'm in 24p? DO i just press the button in the back, and set the number on the dial that i want it to set to???
thanks

Stefan Scherperel · January 12th, 2004, 10:27 AM

at the very end of the scene file setup ( where you change you settings) it will ask you to name the new scene file, and also ask you to save the settings. Just keep pressing yes until it says "saved". However, do not go to the "int" option, or this will revert it back to the original. I hope this is what you were looking for.

Mike Zorger · January 12th, 2004, 11:02 AM

sounds good to me, i'll try it out.
Thanks

Art Guglielmo · January 13th, 2004, 09:10 AM

So using the INT option, can i revert to factory settings at any time if i screw things up ?

Stefan Scherperel · January 13th, 2004, 10:22 AM

Yes, at least I'm pretty sure that's what it does. I personally havn't reverted back, but that is what the manual says it does.

Mike Zorger · January 14th, 2004, 09:34 PM

ok i f...ed up. i saved some of my 24p under scene 1. How do i go back. Do i just have to undo all of my settings and save again. or what. I cant really remeber how it was before exactly.

Stefan Scherperel · January 14th, 2004, 11:34 PM

ok
1:press menue
2:enter the "scene file" setting
3:go all the way to the bottom, to the setting that says
"save/init"
4:you wil then fave the option of save or Initial. Go to Intitial, and press yes.
5: It will then say "initial ?" go to yes and push still. There you go, factory settings.
