Edius slow motion/High Def Question

[stevenfowlerfilms]

I recently purchased a Sony EX-3 High Def camera. I am currently editing footage I shot at 1080p, and am having trouble whenever I try to slow a clip down. The problem I'm having is that when I apply slow motion using edius, whatever is moving within the shot has a ghostly trail that follows it. It almost looks like a very subtle motion blur. I was curious if the reason this is happening is because my footage is progressive as opposed to interlaced. In short, I was wondering what is optimal when editing high def footage within edius, interlaced or progressive?

Your project setting should match your footage .

If you shoot progressive why would you want to edit interlaced that defeats the purpose of shooting progressive.

A very important thing s people tend to overlook is the monitor connected to the canapus hardware card.
Example is your monitoring solution progressive or how does it display progressive.

dont overlook the original footage - if you had a slow shutter speed then you will get some motion blur recorded on to your cards

I use Panasonic HPX172 - and I found the BEST slow motion clips are NOT done in EDIUS, After Effects, etc - but, doing it in overcrank mode in HPX172. They represent the smoothest slow motion video (without any smearing, etc) you can ever get.

If I understand correctly, the Sony EX3 also has the same ability as HPX172. I shot exclusively in 720p mode at 25 frames/second.

Shooting 1080p will not produce the best slo mo. 1080i is far superior.
Shot my first 1280x720 in 60p with the EX1 and it's fantastic!

Need better? Look for Twixtor.

Good slow-motion comes down to the sampling rate first, then the sampling type (progressive or interlaced).

For example, 120i would give a smoother slo-mo than 60p, even though the individual frames would be half the vertical resolution, because there is an existing sample for each of the target outputs.

Likewise, 30p would produce poor slo-mo compared to 60i. IMHO, 30p in general is of limited use. Because each frame is only visible for a short amount of time, the viewer's perception is tuned more toward consistent motion rather than tiny details in the frame that are quickly out of view.

i'm on edius 6.3,

i have shot in slow motion a kung fu battle with an AF101,

it has been shot in ntsc 59 94 frequency, 1080 30p,
60 fps,

you cant rec in slow motion if you are not in ntsc,
when i change speed frame it changes nothing,

when i look my footage (AVCHD native) on tv, it s great,

when i edit them on edius, i have some ghost move,

i have changed the parameters in fullhd 25p, fields are in progressive,

i have still that ghost that i dont see in native,

thanks for helping me to configure well my project,
i would love to show you soon the video.

thx for support
