15p or 60i?

[joshbm]

Hello all,

I have Sony's VX2000 and I was going to film a "movie". At least my goal is to try and make it look as movie-like as possible. Since a movie is 24p (23.976), I am wondering would you think filming it in 15p would be better, then increasing it to 24p by using something like DynaPel's MotionPerfect (http://www.dynapel.com/com/private/mp_overview.htm)?

Or would you recommend keeping it in 60i then go to 24p. The only problem with that option is deinterlacing artifacts. I looked into blending the fields and that just leaves a ghost behind everything.

The reason I ask is when filmed in 15p it is really crisp picture and I would much rather use crisp picture than a picture in which you can tell it was deinterlaced and filmed on an interlaced camera.

The only real time I will be using 60i is in slow motion areas. If I need slow mo I will take Field A and Field B slow them 50% then using a black/white alpha switch-- giving perfect 50% slow mo. Then using MotionPerfect to further slow the scene (if necessary).

What are your thoughts on any of this?

Thanks!

I recommend using 60i for shooting your "film" and use my AVIsynth - script for reducing it to 24p.

but be sure using a shutter speed of 1/60sec, nothing else!

IMO is shooting in 15p not very good, since you dont have 24p motion information and motionperfect makes very "nice" artefacts....

Okay thanks! I will try it out!

By the way... Your script for 60i to 24p is great!

Edit: One more thing I've heard is that taking off steady cam gives a more "film" look to the shot... is this true?

Thanks!

Do you mean this electronic image stabilization built into most consumer cameras?

I prefer shooting without it and stabilizing afterwards, if nessesary.

Deshaker for Virtualdub can stabilize your Video much better that those cam-internal stabilizators.

Maybe, but you'll loose resolution this way. Internal image stabilisation uses extra pixels as working area, and you get full 720x576 (or 720x480) output, whereas Deshaker gets 720x576 as input, so the output resolution will be smaller.

I know about this issue.
But I've seen cams, that did only a zoom of 720x576 pixels to get the image stabilized (like deshaker does).

Does it work for PAL shooting, aka 50i to 25p?

[scharfis_brain]

jkwarras, just deinterlace your PAL-Video.

kerneldeint will do a very good job for this.

I know i have to deinterlace but i was looking for a proper deinterlace method, trying to avoid ghosting (for ex. in decomb) and fluid picture. I'm looking for a good movie look :)

Is there a way to achieve that with kerneldeint?

[scharfis_brain]

decomb's deinterlacing is always set to blending per default.

use the switch blend=false to get rid of the ghosting. (eg. Fielddeinterlace(blend=false) )

kerneldeint will not produce ghosting.
