Dear Master Sabatini, thank you so much, it finally works now. In fact I had a very similar solution yesterday and was so sure, that this must be right, I was reading the overlay and fade manual entries over and over again, but I missed the fact that -t is needed here and it did not work.

I am stil looking around for other solutions, but the idea is to combine 30 images of 500x500 to a combined total image of 2500x3000 pixels. The reason I would like to use ffmpeg for is the batchfile automation. The smaller images change content so the new total map needs to be updated when

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

Your question interested me, so I googled around and found that FFmpeg can in fact do this with Tile=1x2, although I'm having trouble getting FFmpeg to work with the file names properly. In a script I have on windows I use a cmd wildcard basically to insert the same file name twice, but I'm not

[FFmpeg-user] Question about ffmpeg

2015-01-21 Thread Fedor van der Lee
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

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?
