Vertical resolution explained
Greetings.
I'd like to take back my initial query regarding the vertical resolution in my previous post. Today I found thread more than a year old which may shed some light on it. If you are interested please go here: http://www.dvinfo.net/conf/canon-xh-...est-mtf50.html Another informative discussion is here: http://www.dvinfo.net/conf/canon-xh-...er-dvfilm.html Thanks.

It helps

Does anyone has any experiences with shooting for fast motion with XH A1... just asking before 'pulling the camera trigger'. Thanks, Pavel

Hi Bill and Adrian.
Thanks for your reply. I guess where I'm confused is say if there are 24 or 30 fps second going through the camera, that means that each frame is "exposed at a 1/24th or 1/30th of a second= shutter speed. Adrain, I think the shutter speed example you give would be closer to 1/24th sec, not 1/250. (One second of 24fps film divided by 24 frames= 1/24th sec.) If you shoot 100fps, than each of the 100 frames is exposed for 1/100th of a second, shutter speed. In the above samples, it takes either 24, 30 or 100 frames to make one second of moving footage. I also assume, and correct me on this if I misunderstand, that each "frame" is exposed imediately following the last frame like this: _______________ with no lagtime that might be like this: _ _ _ _ _ _ _ _ Bill, without sounding really off here, is it possible to even do slow motion WITHOUT shooting at a higher shutter speed in a video camera? Thanks for your patients. Jonathan |

I've been with FCP since FCP1. I've been through a lot of upgrades. I'm waiting for FCS3 before upgrading from FCS1. It's more expensive than it used to be with the whole set now. I've been using FCP5 for slow mo with okay results at 60i but would love something better with the software I already have. |

Jonathan, you're still confusing shutter speed and frame rate. Shooting at a higher shutter speed will not give you slow motion. Shooting at a higher frame rate will. But the only relatively cheap cameras that do that are the HVX200 (up to 60 frames per second) and the Sony 1/2" chip EX, which also goes to 60 fps. Unless you use one of those cameras, or a film camera or more expensive camera that does variable frame rates (like Varicam), the only thing you can do is do it in post. There's some software called Twixtor that allegedly helps give better slow motion than standard NLE software.

Bill.
Thanks for working with me on this. I moved this topic back to: http://www.dvinfo.net/conf/open-dv-d...rates-etc.html See my response there. Jonathan |

I'm working on a MAC Pro with Final Cut Pro. Last week I saw a clip on VIMEO with brilliant slow motion footage. All made in Motion and because I have some very nice footage i want to bring down in slow motion I tried to do the same thing. I got the speed down to 25% and the exported .mov clip has been generated after waiting quite a few hours. (more then 10 hours....) The result was indeed very good. But, after that I tried to bring the clip in to FCP again and it kept on crashing. So, no luck there for me. I was wondering if you could tell us about the workflow you use in motion to make slow motion footage. And can you re-import the new footage in FCP? I'm VERY curious about that. Thank you very much in advance, Gert

Troubles in Motion
Hi,
I second to this - issues with Motion, last night I spend several hours to export from FCP 6 to Motion 3 footage for slowmo and because I do not have installed contents so it seems there was no possibility work with it at all. Or I am doing something wrong... I tested demo of Twixtor 4.5 but the rendering time is a quite killer - couple of minutes = several hours. Will test more and share my findings (will take sometime). Thanks. Pavel
