I'm trying to overlay a webm file with transparency over a png background
What I have so far is this
ffmpeg -y -nostdin -i inputvideo.webm -itsoffset 2 -i background.png -filter_complex " [1]format=yuva420p,fade=in:st=0:d=1[i]; [0][i]overlay=x=0:y=0:shortest=1 " outputvideovideo.mp4
The issues with this is that it cuts the duration of the webm video from it's full length to 2 seconds and the image is on top of the webm
I've also tried, amongst other things, ffmpeg -y -nostdin -i background.png -i inputvideo.webm -filter_complex "overlay=(W/w)/2:(H-h)/2:shortest=1,format=yuv420p" outputvideo.mp4 but this just produces a black 0 second length video
I would appreciate any help or insight you can give me
I've solved this with
ffmpeg -c:v libvpx-vp9 -i inputvideo.webm -i template.png -filter_complex "[1:v][0:v] overlay=25:25:enable='between(t,0,20)'" -pix_fmt yuv420p -c:a copy output.mp4

I want to add one or multiple resized images anywhere over the video using ffmpeg. It works well for some position. However, it does not add images to the exact position I want. I have tested it on console and its embedded in php with dynamic variables.
ffmpeg -y -i vid_1561454052.mp4 -i Penguins.jpg -filter_complex
"[0:v][1:v] overlay=221:127:enable='between(t,0,5)'" -pix_fmt yuv420p
-aspect 16:9 -c:a copy vid_1562740969.mp4
Please Help me out...
use loop option
ffmpeg -y -i vid_1561454052.mp4 -loop 1 -i Penguins.jpg \
-filter_complex "[0:v][1:v] overlay=221:127:enable='between(t,0,5)'" \
-pix_fmt yuv420p -aspect 16:9 -c:a copy vid_1562740969.mp4
I am looking to overlay a video on top of another video and then also add a fade in and fade out PNG.
I have the current command which works perfectly in merging two video files one on top of the other.
ffmpeg -y -i output.mp4 -i transparent.mp4 -filter_complex "[1:v][0:v]scale2ref[ua][b];[ua]setsar=1,format=yuva444p,colorchannelmixer=aa=.7[u];[b][u]overlay=eof_action=pass[v]" -map [v] awsome.mp4
I need to now add a PNG on it as well that fades in at 1s and fades out at 9.5s.
Appreciate any and all advice.
Use
ffmpeg -y -i output.mp4 -i transparent.mp4 -loop 1 -t 10 -i image.png -filter_complex "[1:v][0:v]scale2ref[ua][b];[ua]setsar=1,format=yuva444p,colorchannelmixer=aa=.7[u];[b][u]overlay=eof_action=pass[v];[2]fade=in:st=0:d=1:alpha=1,fade=out:st=8.5:d=1:alpha=1[i];[v][i]overlay[v]" -map [v] awsome.mp4
If the PNG needs to be scaled to video size, use scale2ref for the image as well.
ffmpeg -y -i output.mp4 -i transparent.mp4 -loop 1 -t 10 -i image.png -filter_complex "[1:v][0:v]scale2ref[ua][b];[ua]setsar=1,format=yuva444p,colorchannelmixer=aa=.7[u];[b][u]overlay=eof_action=pass[v];[2][v]scale2ref[i][v];[i]fade=in:st=0:d=1:alpha=1,fade=out:st=8.5:d=1:alpha=1[i];[v][i]overlay[v]" -map [v] awsome.mp4
I need to add an image for one second at the end of a .mp4 video file using FFMPEG. My video size is WxH and my image size is MxM, so video and image sizes are different.
I have tried different options in order to add the image at the end of the video as:
ffmpeg -i "concat: videoIn.mp4|image.jpg" -c copy videoOut.mp4
or
ffmpeg -i videoIn.mp4 -loop 1 -t 1 -i image.jpg -f lavfi -t 2 -i anullsrc -filter_complex "[0:v][0:a][1:v][2:a] concat = n=2:v=1:a=1[v][a] -c:v libx264 -c:a aac -strict -2 -map" [v] "-map" [a]" videoOut.mp4
but none gave me the result I need.
Can someone help me?
Kind regards
Use
ffmpeg -i videoIn.mp4 -loop 1 -t 1 -i image.jpg -f lavfi -t 1 -i anullsrc -filter_complex "[1:v]scale=WxH:force_original_aspect_ratio=decrease,pad=W:H:'(ow-iw)/2':'(oh-ih)/2'[i];[0:v][0:a][i][2:a] concat=n=2:v=1:a=1[v][a]" -c:v libx264 -c:a aac -map "[v]" -map "[a]" videoOut.mp4
The image is resized to fit within a WxH frame size and then padded to get the video's frame size.
You'll need ffmpeg 3.4.2 or later.
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. :)

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.
