FFAStrans forum

Hi,

It may be obvious but I've tried without success.

I want to take a single PNG and make it into a five second video. Not sure how to do this?

Thanks!

Hey Graham,

if you can use A/V decoder, just do it with a Custom Avisynth script:
Above means repeat frame 0 250 times, i think it would also work when written as m_clip=loop(m_clip,250)

Let me know if it works for you!

EDIT: we also have it in the stills decoder, i forgot... i believe it will do more or less the same internally but not 100% sure about it

Yep. I mean, kinda, but yeah. Well this just like the A/V Decoder is going through an indexer, in this case ImageSource().
If we were writing a script from scratch, we would use the indexer to index the image and specify how many frames and at what framerate we want the image to become in the uncompressed A/V stream in our beloved frameserver.

For instance, to get 2 seconds (i.e 50 frames at 25fps) we would specify: and that's exactly what we're doing in FFAStrans as well, namely using the indexer.
where the end is always calculated (i.e converted in frames) from the variable read from the user input and so are the fps.
