try to render without the audio, if it works then export the audio (wav) then mux with tsmuxergui

I work with 12 canon HV20, for three years now.They are great cameras. one thing only, they are ‘ fragile”. one day you don’t know why, on one camera the zoom started to play by itself, an other day one got a 5 magenta blue cast , etc …Great cameras, but only consumer cameras. So if you are working 5 days a week try to get some spare ones.

studder, not stutter sorry;

Did you shot the runners coming forward you, or 3/4 or parallel to to the camera frame going from the left to the right ?

how did you set up your camera ? interlaced or progressive; cinemode or tv; shutter at 1/50 or 1/120 ? …

let’s go farther … my camera is going to be steady on a tripod. I remember when I used ultimatte long time ago I was always shooting my empty blue screen before the real shooting so my chromakey was clean.

So what if i shoot the landscape without the runners ; then I use this still to isolate the runners then I motion blur the difference between frame 1 and frame 2 then between frame 2 and frame 3 and so on ?

what do you think ?

[Jacques Davis]

it’s worst then you think and it’s easier; worst because I shoot ten cameras together ( google me) for the rest it’s easier: it will be 9 am when I start shooting and 10.15 when I stop. the sun will be low and will only change few degrees( astronomie calculation ).I have no problem to control my light, and exposure.

All I know is that around 1/50 to 1/100 I have too much blur and around 1/250 it start to studder …

Thanks anyway for your time

[Jacques Davis]

no idea with ae and some kind of motion blur

[Jacques Davis]

i did tenth of them … I am not happy yet

[Jacques Davis]

your right,
that’s why I am looking to smooth only the moving part ; the difference between two frames ? I wonder

[Jacques Davis]

I capture from a canon hv20 hdmi port to a blackmagic intensity.
I code apple prores ( for apple color )

I wondered if i would get somewhere by:

use a fast shutter to have a sharp picture
use some kind of after effects filter to smooth only part of the picture which have a big difference between two frames ( legs, feet, arms )

I am a long time user of ae ( cosa after effects ) but I mostly use it to compose and not for effects …

google me

and thanks, I like your posts

Think of my work as a picture:

I will shoot one hour of marathon without moving my camera.
outside the studder problem my movie will be clean, no black crush, no
overexposed white. That I know how to do.

Then I will grade my movie; plain color, no fancy stuff

no editing.

Then the movie will play , endlessly, from a mediaplayer ( 1080p HDMI )
on a 23″ lcd screen ( samsung f2380 to be precise).

that’s all !

I just want a clean picture.
