I am overlaying a video on top of an image.
Using this command:
ffmpeg -i image.png -i input.mp4 -filter_complex "[0:v][1:v] overlay=10:10:enable='between(t,0,38)'" -pix_fmt yuv420p -c:a copy output.mp4
I understand the overlay=10:10 is the positioning but I can't seem to work out how to resize the overlay video (input.mp4).
I think I need to use scale but not sure how to.
Any help on scaling the overlay video would be appreciated!
With filter_complex you can combine commands and make named outputs
Try something like this:
ffmpeg -i image.png -i input.mp4 -filter_complex "[1:v]scale=320x240[scaled_v];[0:v][scaled_v] overlay=10:10:enable='between(t,0,38)'" -pix_fmt yuv420p -c:a copy output.mp4
Just change resolution to what you need instead of 320x240.
If you need image overlay on top of video, swap [1:v] and [0:v]

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 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 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 have an image and a video (same width). I now want to use ffmpeg to add the image above the video. Google and other SO threads the use of the vstack filter_complex tag, which works great - except that it puts the image under the video.
I've tried putting the image first and then the video, but this doesnt work. I've also tried giving the vstack command reverse inputs, but also didnt work!
The video may also contain audio which I would need to keep.
See code below:
// Works, but puts image below video (instead of above)
ffmpeg -i test.mp4 -i text.png -filter_complex vstack result.mp4
// Doesn't work at all
ffmpeg -i test.mp4 -i text.png -filter_complex '[1:v][0:v]vstack' result.mp4
// Doesn't work at all
ffmpeg -i test.mp4 -i text.png -filter_complex '[1:v][0:v]vstack=inputs=2[v]' -map '[v]' -map 0:a result.mp4
Google / SO did not yield any tips on how to achieve this so far. Do you know a solution?
Use
ffmpeg -i test.mp4 -i text.png -filter_complex '[1:v][0:v]vstack' -c:a copy -pix_fmt yuv420p result.mp4
Videos and images can have different pixel formats. When the various inputs to a stack filter don't have the same format, the filter picks the format of the first input and converts all other inputs to that format. However, some video players don't support a wide variety of formats. yuv420p is the widely supported format and so the command above forces the output to that one. Audio, if present in the MP4, will get carried over.
ffmpeg -i test.mp4 -i text.png -filter_complex '[1:v]format=yuv444p[img];[img][0:v]vstack' -c:a copy -pix_fmt yuv420p result.mp4
i need to create a zoom effect with frame image background instead of black background
how is possible this
please help me
this is my command
ffmpeg -i duke2.jpg -filter_complex "pad= w=560:h=200:x='(ow-iw)/2':y='(oh-ih)/2',zoompan= z='zoom+0.002':d=25*4:s=1280x800" -pix_fmt yuv420p -c:v libx264 zzout.mp4
One way is,
ffmpeg -i duke2.jpg -i bg.jpg -filter_complex
"[0]pad= w=560:h=200:x='(ow-iw)/2':y='(oh-ih)/2':color=black#0,format=yuva444p,
zoompan=z='zoom+0.002':d=25*4:s=1280x800[fg];[1][fg]overlay=(W-w)/2:(H-h)/2"
-pix_fmt yuv420p -c:v libx264 zzout.mp4
