Hi Stefano, regarding timestamps - are you suggesting things that can be done with the setpts filter? The example I posted works very well with static images, no timestamp manipulation needed here, but I can not find a way to add fades to all the images - how do come timestamps into play here? Th

I'll have a look at it when I can download the zipped version of it, it seems to be down. I can't install it here. For now I managed to get it working with ffmpeg and it works great. Lee. -Oorspronkelijk bericht- Van: ffmpeg-user-boun...@ffmpeg.org [mailto:ffmpeg-user-boun...@ffmpeg.org]

Yeah, this solution seems to work perfectly, I can keep repeating the commandline in a batch and create a huge image. Thanks everyone. Lee. -Oorspronkelijk bericht- Van: ffmpeg-user-boun...@ffmpeg.org [mailto:ffmpeg-user-boun...@ffmpeg.org] Namens Moritz Barsnick Verzonden: woensdag 21

Hello everyone, I know ffmpeg can be used to convert an image sequence to a movie, but would it also be possible for ffmpeg to combine two jpeg images to a single jpeg image? For example, two images with a size of 500x500 pixels each to a result image of 500x1000 pixels. Kind regards, Lee ___
