Making a clip from one (1) image

[Prakel]

Hi there,

what are the possibilities to create a clip of arbitrary length from one image? I'd like to use that for a mask.

So far I used

msk=imagesource("D:\someMask.jpg").convertToYV12().loop(465)

The problem is, for some reason the base image creeps very slowly (changes its position) within the clip and makes the resulting clip useless as a mask.

Are there other ways to get a clip from an image?

It shouldn't creep. Is it maybe the case that you have sequentially numbered images at the same folder (say someMask001.jpg, etc.) ? Note that ImageSource("afile") equals ImageSource("afile", 0, 1000) and produces a clip with 1001 frames. To produce a 465 frame clip with one image in your example you should do: msk=imagesource("D:\someMask.jpg", 0, 0).convertToYV12().loop(465)

Here's how I do it:

ImageSource("1157484270_oav.jpg", start=1, end=587,fps=23.976023976023976023976023976024)

:).

This way you can insert it into a 23.976 clip(guys on the forums showed a way in which you don't have to insert the long 23.97... Number, and I have the link to that thread somewhere if you wanna).

Anyway, in the above example you have 587 frames in a movie of 23.976 FPS.

Hi there,

AssumeFPS is more flexible since you can use it to match the FPS of an existing clip or can specify a rational number (e.g. 24000/1001).
