Creating videos from images
-
Hi I am working on some software that needs to be able to create videos from an array of images and I need to create the video as fast as possible. The requirements I have been given are that the software needs to be able to create 6 minute video at 640x480 resolution and 25 fps within about 5 - 10 seconds. Can anyone give me any advice or help? Thanx

I don't think that can be done, it amounts to generating 1000 frames per second. :)

That requers processing power of 0,77GB/s - 1,54GB/s (asuming the images in the video is in 24bit, and this is for "pure" image reading, any processing like resizing, image filters and so on must be added), you better whipe the dust from that old asm book and optimize like mad.

Ok thanx for the reply. Im not sure how to create video from images. Does anyone know of any example code I can look at?

all video is is a very fast slideshow. Standard television FPS is 24, movies are 30. "Don't re-invent the wheel." applies here. There are plenty of commercial (and some free) applications out there that can do this. I would seriously look at using one. Look at movie maker or something like that, because taking an image, resizing it to the proper dimensions and resolution, saving its relative position and saving it along with the other images to a video format is a pain you probably never want to go through.

Maybe I should tell you more about the application im developing. Im working on a camera monitoring application that buffers video from up to 12 cameras and records events when a signal is recieved. The buffer is just an array of images that is saved to disk in 5 second chunks. So at the end of recording the event I need to create a video file from the images. I have some code that works and creates a video file but its far to slow. Im just wondering if theres anything faster. If you could point me at some code I could look at or just point me in the right direction it would be apreciated. Thanx.
