1080i 60 in FCP to film with magic bullet
the idea: shoot 1080 60i onto p2. bring into final cut pro, which will mandate the 29.97 timeline. edit. then run the magic bullet to pull it to 24 fps. then we print to film.
this post comes with very little knowledge of magic bullet’s capacity to handle such a task.
the objective is to print to film. but also to get 100mps out of the camera. what, that is living now among us would be the best solution.

I don’t see the problem with shooting 720p24 24PN. That gets you 24 full frames of video that will transfer directly to film without any conversion whatsoever.
The camera is a 720p native camera, so, IMHO, that would be the best route. That is the route I’d take if I were doing it.

Actually Shane the camera captures the signal as it comes off of the CCD as a 1080P/60 signal and then all conversions are made from there. THe 720P/24PN is a very cool mode though with its ability to offer quality with reduced data requirements.
Best,

Well then…thanks for the correction.
I said I knew the POST workflow like my mother…not the inner workings of the camera. Time to bone up on that area I suppose.

just curious as to the conversions you are speaking of after the info hits the ccds. and i guess which specific mode of shooting this 1080p/60 comment is in reference to.
with regards to the 720p/24pn. it just seems like such a drop in data info to expect a pretty film print from. knowing that the 1080/60 stuff is at 100mps and the 720p/24pn is under 75.
this sitch is such a peculiar debate amongst ourselves. the camera offers this nice high quality output, but doesn’t allow a true comfy edit.

This is the stage where the signal comes off of the CCDs, has gone through the spatial offset process and then is turned into a digital signal. It is captured as a 1080P picture, which is why I mentioned it in response to the comment from Shane as he said it was a 720P native camera, if anything it is 1080P camera. The CCDs are not 1080 but indeed the circuitry grabs the pictures coming off of the CCD at 1080P. This is not a recording mode but rather a capture mode. Then after the camera functions like color and detail are handled, it is then moved into the format of choice, like 720P or 480i or 1080i/24P. In the 24P modes thes are capture at the front end in the correct capture rate and thus the 24P will have the right “look” for 24P.
>with regards to the 720p/24pn. it just seems like such a drop in data info to expect a pretty film print from. knowing that the 1080/60 stuff is at 100mps and the 720p/24pn is under 75.
The drop in data is not because of a drop in quality. The 100mbs in DVCPRO HD is based on 60 frames per second. When recording in the 24PN mode only the the 24 frames are recorded. This means that 24/60ths of the data are being recording. The frames them selves are still the same size as if there were 60. So if we do the math then, we divide the 100mbs by 60 which gives us 1.66Mbs per frame. Multiply that by 24 and you end up with 40Mbs for the 24 frames. This means that in that same amount of memory you can store 2.5 times as much footage as that in 24P over 60P like the VariCam.

Not sure what you mean here. The edit is very simple, you can either shoot in 720P/24PN, gain more time at 2.5 minutes per gigibyte. You can shoot in 1080i/24PA and extract out but this will cost you at 1 minute a gigabyte. Both of these are handled very easily on the edit side, you just need to make decisions before you start.
Hope that helps,

Don’t have the camera yet but what I have read on the boards. When shooting at 1080i I have heard the image countains more noise then the 720 version. People with the camera can tell you more about that. Since you are going to film you might want to take that in to your thought process. More grainy video image added to the grain of your film.
Just my 2 cents.

If you have the storage and the work flow I would go 1080. But the only way ro really know is to do a test of each through to film out and compare.
