I managed to create a video from set of non-sequential images and attached an audio to it. Also I added a "Copyright" text on top right hand corner so that the text appears throughout the video. However, I would like that text to appear only on the last image. How should I change my code below to address this?
ffmpeg \
-thread_queue_size 512 -f image2 -pattern_type glob -framerate 1/3 \
-i '*.jpg' \
-i 'audio.mp3' \
-c:a aac -c:v libx264 \
-vf scale=640:480, format=yuv420p, drawtext="text='Copyright':fontcolor=white:box=1:boxcolor=black#0.5:boxborderw=5:x=w-tw-5:y=5" \
-preset medium \
video.mp4
Isolate the last image from the glob and then concat it:
ffmpeg \
-pattern_type glob -framerate 1/3 -i '*.jpg' -framerate 1/3 -loop 1 -t 5 -i last/img.jpg -i audio.mp3 \
-filter_complex \
"[0:v]scale=640:480,setsar=1[v0]; \
[1:v]scale=640:480,setsar=1,drawtext=text='Copyright':fontcolor=white:box=1:boxcolor=black#0.5:boxborderw=5:x=w-tw-5:y=5[v1]; \
[v0][v1]concat=n=2:v=1:a=0,fps=25,format=yuv420p[v]" \
-map "[v]" -map 2:a -c:v libx264 -c:a aac -shortest -movflags +faststart video.mp4

I'm trying to generate a perfectly looping mp4 from three inputs:
A background png image
An image sequence of transparent png images with the number of particles increasing
Another image sequence of transparent png images with the number of particles decreasing
I'm currently trying to achieve this with two commands (I have to use 'overlay' twice). The problem is that after the second command the video (test2.mp4) freezes for the last 3 seconds. Why does it happen? ARe there any other commands I could try to use?
First command:
ffmpeg -framerate 30 \
-pattern_type glob -i 'images/increase/*.png' \
-framerate 30 \
-i screens/Background.png \
-i audio/50-White-Noise-10min.mp3 \
-filter_complex "[1:v][0:v] overlay" \
-preset slow -c:a copy -shortest -c:v libx264 -pix_fmt yuv420p test.mp4
Second command:
ffmpeg -framerate 30 \
-pattern_type glob -i 'images/decrease/*.png' \
-i test.mp4 \
-filter_complex "[1:v][0:v] overlay" \
-preset slow -c:a copy -shortest -c:v libx264 -pix_fmt yuv420p test2.mp4
The solution was to do what Rajib commented: chain the overlay filters and do it all in one command:
ffmpeg -framerate 30 \
-i screens/Background.png \
-framerate 30 \
-pattern_type glob -i 'images/increase/*.png' \
-framerate 30 \
-pattern_type glob -i 'images/decrease/*.png' \
-i audio/50-White-Noise-10min.mp3 \
-filter_complex "[0][1] overlay[out],[out][2] overlay" \
-c:a copy -shortest -c:v libx264 -pix_fmt yuvj420p loop.mp4
I got currently 2 different ffmpeg scripts which I want to combine. I do not have good ffmpeg experience and those codes are mostly googel code so please be patient with me
The first code is concating 3 videos:
ffmpeg -y -i "$vid1" -i "$fp" -i "$vid1" -filter_complex \
"[0:v]scale=$cResolution:force_original_aspect_ratio=decrease,pad=$cResolution:(ow-iw)/2:(oh-ih)/2,setsar=1,fps=30,format=yuv420p[v0]; \
[1:v]scale=$cResolution:force_original_aspect_ratio=decrease,pad=$cResolution:(ow-iw)/2:(oh-ih)/2,setsar=1,fps=30,format=yuv420p[v1]; \
[2:v]scale=$cResolution:force_original_aspect_ratio=decrease,pad=$cResolution:(ow-iw)/2:(oh-ih)/2,setsar=1,fps=30,format=yuv420p[v2]; \
[0:a]aformat=sample_rates=48000:channel_layouts=stereo[a0]; \
[1:a]aformat=sample_rates=48000:channel_layouts=stereo[a1]; \
[2:a]aformat=sample_rates=48000:channel_layouts=stereo[a2]; \
[v0][a0][v1][a1][v2][a2]concat=n=3:v=1:a=1[v][a]; \
[v]drawtext=text='example..':y=h-line_h-$h3:x=w/30*mod(t\,20):enable='gt(mod(t,$dr2),$Introdr_rounded)'[v]; \
[v]drawtext=text='example..':y=h-line_h-$hcentral:x=w/20*mod(t\,100):enable='gt(mod(t,$dr2),$Introdr_rounded)'[v]; \
[v]drawtext=text='example..':y=h-line_h-23:x=w/30*mod(t\,20):enable='gt(mod(t,$dr2),$Introdr_rounded)'[v]" \
-map "[v]" -map "[a]" -c:v libx264 -crf 22 -preset veryfast -c:a aac -movflags +faststart "$fp_dest"
The second code is overlay a background mp3 in endless loop to the created video from above. Its important to know that this code does overlap the audio of the video and does not replace it. In future I will lower the volume of the mp3 files to work as background music
ffmpeg -y -i "$fp_dest" -filter_complex "amovie=$audio:loop=0,asetpts=N/SR/TB[aud];[0:a][aud]amix[a]" -map 0:v -map '[a]' -c:v copy -c:a aac -b:a 256k -shortest ./test.mp4
So currently I got 2 steps which I want to combine into 1 step. Can you please help me to include the second code into the first one without change any logic of the code?
Use amix to mix the music and the concated audio. stream_loop is applied to the music to loop it.
ffmpeg -y -i "$vid1" -i "$fp" -i "$vid1" -stream_loop -1 -i "$audio" -filter_complex \
"[0:v]scale=$cResolution:force_original_aspect_ratio=decrease,pad=$cResolution:(ow-iw)/2:(oh-ih)/2,setsar=1,fps=30,format=yuv420p[v0]; \

I am trying to stitch multiple images with some zoom-pan happening on the images to create a video.
Command:-
ffmpeg -f lavfi -r 30 -t 10 -i \
color=#000000:1920x1080 \
-f lavfi \
-r 30 -t 10 \
-i aevalsrc=0 \
-i "image-1.png" \
-i "image-2.png" \
-y -filter_complex \
"[0:v]fifo[bg];\

[1:a]amix=inputs=1:duration=first:dropout_transition=0" \
-map "[bg]" -vcodec "libx264" -preset "veryfast" -crf "15" "output.mp4"
The output is not as expected, it only zooms only on the first image, the second image is just static.
FFMPEG version - 4.1
Use
ffmpeg -f lavfi -i color=#000000:1920x1080:r=30:d=10 \
-f lavfi -t 10 -i anullsrc \
-i "image-1.png" \
-i "image-2.png" \
-filter_complex \

-map "[bg]" -map 1:a -vcodec libx264 -preset veryfast -crf 15 -y "output.mp4"
For lavfi sources, it's best to set frame rate and duration where applicable within the filter.
Since you're not looping the images, -t won't have any effect. Since zoompan will set fps in its output, you can skip input rate setting. And since it's a single image, setpts before zoompan has no relevance. It should be set only on the zoompan whose timestamps need to be shifted.
Since you've only one audio, no point sending it to amix - there's nothing to mix with! Just map it directly.
I have this command to generate a slideshow with zoompan from a list of images, but it applies the same zoompan to all pictures.
ffmpeg -r 1/5 -i img%03d.jpg -i 1.mp3 -c:a aac -c:v libx264 -r 25 -pix_fmt yuv420p -vf "zoompan=z='if(lte(zoom,1.0),1.2,max(1.001,zoom-0.0015))':d=100" out.mp4
How can I get it to have different zoompan parameters for each image?
Input each image individually and provide a separate zoompan per image. Then concatenate with the concat filter.
ffmpeg \
-i img001.jpg \
-i img002.jpg \
-i img003.jpg \
-i audio.mp3 \
-filter_complex \
"[0:v]zoompan[v0]; \
[1:v]zoompan[v1]; \
[2:v]zoompan[v2]; \
[v0][v1][v2]concat=n=3:v=1:a=0,format=yuv420p[v]" \
-map "[v]" -map 3:a -shortest out.mp4
You'll need to adapt this example to use whatever zoompan values you want.
I am having trouble combining these 3 passes in ffmpeg into a single process.
Is this even possible?
