AviSynth - 'Animate'

[Hungarian]

Hello,

I have two, possibly three,difficulties with AviSynth video creation.
The overall aim is to make ashort video from a still image.

1. For one of my scenes I wouldlike to float an image in from the left edge of a ‘black’ 400 x 300 pixel frameso that the whole image fills the frame over a period of 88 frames. The aimed for effect islike sliding a physical picture into a frame.

2. For two other scenes, illustratingaudio sampling and quantisation, I would like at regular intervals, say everyfifth frame, insert successive thin vertical lines across an image, followed bysimilar horizontal lines moving up a different image.

Are there an appropriate ‘animate’expressions in AviSynth?

Guidance and advice will beappreciated.

Thank you

For #1 , you can probably use transwipe from transall plugin

I don't understand what you are asking in #2? do you want the lines to animate vertical lines to the right, horizontal lines upward ?

TransSlideIn looks more like what he wants.

Hello,

Thank you for advice.

Re 2. I want to draw vertical lines at regular intervals i.e. progressing from left to right accross an image
Additionally, but on a seperate image, i want to draw horizontal lines at regular intervals from the bottom of the image to the top of the image.

The effect I am aiming for is like a sheet of lined writing paper viewed in landscape orientation and then viewed in portrait orientation e.g.
| | | | |
| | | | |

Further advice will be appreciated.

One way to add the lines to your clip is to overlay a blank clip of the desired color using an appropriate mask to get the line pattern. The mask may be created using the MaskTools function mt_lutspa().

Write a function that produces the lines you want, with a paramater to specify the (vertical or horizontal) position of the first line. Then to make the lines move, you can Animate this function, varying the parameter.

This is not a trivial task so you may need further help, especially if you are not familiar with MaskTools.
Start by reading the relevant documentation and ask again if you get stuck.
