Hi I am new in FFmpeg,
I have made video from slideshow of sequential images (img001.jpg, img002.jpg, img003.jpg....). Using following commands in Ubuntu 14.04
ffmpeg -framerate 1/5 -i img%03d.jpg -c:v libx264 -r 30 -pix_fmt yuv420p -vf scale=320:240 out.mp4
But now I want to put animation like fade-in, fade-out between each sequential images, I want to generate video,
can anybody help me how to make it, i have searched lots of things but could not get....
The best way to do this is create intermediate mpeg's for each image and then concatenate them all into a video. For example, say you have 5 images; you would run this for each one of the images to create the intermediate mpeg's with a fade in at the beginning and a fade out at the end.
ffmpeg -y -loop 1 -i image -vf "fade=t=in:st=0:d=0.5,fade=t=out:st=4.5:d=0.5" -c:v mpeg2video -t 5 -q:v 1 image-1.mpeg
where t is the duration, or time, of each image. Once you have all of these mpeg's, you use ffmpeg's concat command to combine them all into an mp4.
ffmpeg -y -i image-1.mpeg -i image-2.mpeg -i image-3.mpeg -i image-4.mpeg -i image-5.mpeg -filter_complex '[0:v][1:v][2:v][3:v][4:v] concat=n=5:v=1 [v]' -map '[v]' -c:v libx264 -s 1280x720 -aspect 16:9 -q:v 1 -pix_fmt yuv420p output.mp4
This gives you the desired video and is the simplest and highest quality solution with ffmpeg. Let me know if you have any questions about how the above command works.

Here are the images I have in my folder:
img001.png
img002.png
They are stored in c:/frames.
Because that my frames are not shown correctly, used the FPS filter video shown below (documentation from https://trac.ffmpeg.org/wiki/Slideshow):
ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf fps=25 -pix_fmt yuv420p out.mp4
I tried running on my VLC media player but it still doesn't work. It only shows one image.
The last frame of an image sequence will only be shown for an instant. Use tpad filter to clone it once and then apply other filters like fps.
ffmpeg -framerate 1/5 -i img%03d.png -vf "tpad=stop=1:stop_mode=clone,fps=25" -pix_fmt yuv420p -c:v libx264 out.mp4
I am trying to use ffmpeg to replace the video track in a video file with a still image. I tried some commands I got from other questions such as the one here
ffmpeg -i x.png -i orig.mp4 final.mp4
ffmpeg -r 1/5 -i x.png -r 30 -i orig.mp4 final.mp4
But these didn't work. I'm not sure which of these arguments are required or not. The output should be accepted by YouTube as a valid video - I was able to simply remove the video track, but apparently they don't let you upload a video without a video track.
You can try looping the still image like this:
ffmpeg -loop 1 -i x.png -i orig.mp4 final.mp4
Then you can tweak the encoding process by introducing the following quality parameters:
ffmpeg -loop 1 -i x.png -i orig.mp4 -crf 22 -preset slow final.mp4
they are described here.
If your colorspace gets rejected by YouTube you can try adding: -pix_fmt yuv420p.
Solution: A final solution is something like this:
Where -t 30 is an example duration of 30 seconds.
Using -c:a copy will directly copy the original audio without a new re-encoding (is faster).
ffmpeg -loop 1 -i x.png -i orig.mp4 -map 0 -map 1:a -c:v libx264 -pix_fmt yuv420p -crf 22 -preset slow -c:a copy -shortest final.mp4
I am trying to take a single image and add audio resulting in a video playing the entire song with that single image; much like you see for YouTube videos for songs. The command I am using is from this link: https://askubuntu.com/questions/868283/image-audio-mp4-how-to-make-video-smaller
This is the command:
ffmpeg -loop 1 -framerate 1 -i image.png -i song.aac -c:v libx264 -preset veryslow -crf 0 -c:a copy -shortest output.mp4
It works as intended for having the video file be a small size, and the song plays as well, but depending on the image I used, some of the images appear 'Green' when playing the video.
However though, this command works for any image used:
ffmpeg -loop 1 -framerate 1 -i image.jpg -i music.mp3 -c copy -shortest output.mp4
But the result is a very big file whereas I would like it to be smaller. Any help would be greatly appreciated! Thank you!
FFMpeg version: 4.3.1
The command you used from the answer you linked to is for YouTube specifically and even says, "your player probably won't like it but YouTube will". I'm assuming you're using a player and not YouTube.
In the same answer is another command under Widest compatibility for any player:
ffmpeg -loop 1 -i image.png -i music.mp3 -vf "scale='min(1280,iw)':-2,format=yuv420p" -c:v libx264 -preset medium -profile:v main -c:a aac -shortest -movflags +faststart output.mp4
Try that instead.
I am trying to create a video from still images using ffmpeg. The command I use to do this is
ffmpeg -y -r 3 -i input_images%03d.png -c:v libx264 -vf fps=24 -pix_fmt yuv420p output.mp4
However, I would like to overlay this video on still image, without creating a video of the still image first. So, for example, if I have the following images
[still, frame1, frame2, frame3]
I'd like a command to create a video of frame1, frame2, and frame3 overlayed on still.
all with one command. Is there a way to do this?
I've looked at several answers to related problems (e.g., Add image overlay on video FFmpeg) but they don't answer my question, exactly.
Use
ffmpeg -framerate 24 -i still.png -framerate 3 -i input_images%03d.png -c:v libx264 -filter_complex "overlay=x='(W-w)/2':y='(H-h)/2'" -pix_fmt yuv420p -y output.mp4
I want to convert jpg images to mp4 video without resizing image(keep original images size and well formated video)
I have tried lot's of solutions of ffmpeg and imagemagic (links given below)but both crop images after converting in video format and i want a video from images with original image size.
Solution will be appreciated with ffmpeg or imagemagick. :)

ffmpeg -framerate 1/5 -i na%03d.jpg -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4
on large image(1600X1200) its execute successfully but not generate a smooth video.
on small image(300x168) its show error. i also try this command on small image
ffmpeg -framerate 1/5 -i abc%03d.jpg -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4 -vf "scale=trunc(iw/2)*2:trunc(ih/2)*2"
this work for me i use this in loop
