how to fade two images with ffmpeg
1er mai 2016, par steveI have two images and I want to create a simple fading transition between them.
I also want the final output to be a sequence of images rather than a video ?
So if the fading transition was 10 frames long I’d want the output to be a sequence of 10 images.How can I achieve this with ffmpeg ?

Concatenating Video Files using FFMPEG YUV issue
3 novembre 2015, par SpoiledTechie.comI am concatenating three videos with FFMPEG.
The 1st and 3rd video of the concatenation were pulled from an AVI file using FFMPEG and converted into MP4.
Their codec information is below.
The 2nd video in the concatenation is compiled using FFMPEG. I am compiling frames with FFMPEG to create this video.
Its codec information is below.
As you can see, the videos share the same codec, resolution and frame rate.The only thing they don’t share is the Decoded format. One being 4:4:4 and one being 4:2:2
I think I understand what YUV means from this link, https://msdn.microsoft.com/en-us/library/windows/desktop/dd391027%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396
When I concatenate these three videos together, using concat demuxer, it works, but when I try to watch the final video, the video shows the first file playing just right, then the 2nd video in the final video shows up BLANK and the third video plays just fine as well.
So my question is, how do I concat 3 MP4 files, but change what seems to be the decoded format for the 2nd video to 4:2:2. When I compile the frames, I imagine I can change the YUV format, but I don’t know how just yet.
