he,
im planning to use avisynth as a video-assist for Stopmotionanimation.

i use an old 16mm filmcamera for the frames wich doesnt have any digital feature. the problem is, that i cant compare 2 sequenced frames. i mean i dont know exactly where the character(for example) was at the last frame. but i have to know that while animating it.

so, i where thinking about the following:

setup is:
1.)16mm Camera
2.)DigiStillCam or WebCam
3.)Computer with Avisynth

i'll stick the WebCam on the 16mm Camera and connect it to the Computer.
whenever i shot a frame with the 16mm i also shot one with the WebCam.

what i want to do with avisyth is to output rotatory the live-frame and the picture.jpg i shot before (wich is also shot by 16mm). this would let me control the animation and would result in way better smooth-motion.

this should be possible, right?

and the other question is: is there avisyth-like port for linux?
if not i'll go on and use Windows.

thank you!

I would personally prefer DigiStillcamera. Many (of the more expensise) cameras can be controlled from a computer - otherwise you can most likely get an external trigger for your camera, so you don't risk shaking the camera.

If you are better experienced with 16mm, it is also a very good choice, except perhaps a bit more expensive. But you need a $1000 DigiStillCam to get similiar quality.

I would not use AviSynth before you have the frame sequences from your camera.

And no - there is no linux version.

he sh0dan,

yeah i thought about a DigiStillCamera for shot the whole movie.
but - its really expensive, this camera would require full manual control (f-stop, refocus,..) > 1500$ - 10000$ cant spend 10% of this...

and i already have a 16mm bolex so i have to do the film with it.
the WebCam doesnt need a good quality because i use it only for previewing the frame i want to shot with my 16mm + compare it with the previous shot.

do you understand it? its difficult for me to explain because my english is really bad.

what do you mean with "I would not use AviSynth before you have the frame sequences from your camera."?
i only want to loop 2 jpg's for comparing it. isnt it possible?

i made a quick sketch and attached it, so you can see how it will look.

he people,

i think i didnt articulte me correct and it wasnt necessary to confuse you with that 16mm thing.

the only thing i want to know is, if its possible to make a avisynth script wich plays back a *.JPG for about 25 frames and after this a WebCam-stream (also for 25 frames or 1 second). i saw somewhere a script wich could load some JPG's - so this should work. but i dont know how to load a webcam-stream in the avisyth script. i dont have a WebCam now, so i cant try and play arround a little bit. it would be nice if someone could explain me how to do so!

thank you!

Have a look at ImageReader (http://www.avisynth.org/index.php?page=Image). It seems to do what you request.
