ffmpeg - Sync Audio with image position (Audio Slideshow) - image

How can i start the audio Files at the same position as the pictures? (This is for a Image slideShow with changing Audio)
ffmpeg -loop 1 -t 19 -i 1.jpg -loop 1 -t 19 -i 2.jpg -i 1.mp3 -i 2.mp3
-filter_complex "
[0:a]adelay=19s:all=1[1a];
[1:a]adelay=24s:all=1[2a];
[0:v]scale=1280:720,pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1[0p];
[1:v]scale=1280:720,pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1[1p];
[0p][1p]xfade=transition=fade:duration=1:offset=19[1x];
-map [1x] -c:v libx264 -c:a copy -t 39 out.mp4


ok i found a solution to position audio files by seconds with Images.
just use this structure
and Paramter "adelay" for an audio offset
ffmpeg -loop 1 -t 10 -i "1.jpg" -loop 1 -t 10
-i "2.jpg" -t 5 -ss 0 -i "audio1.mp3"
-t 10 -ss 10 -i "audio2.mp3"
-filter_complex "[2]adelay=1000:all=1[a1];
[3]adelay=2000:all=1[a2];
[0:v]scale=1280:720,pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1[0p];
[1:v]scale=1280:720,pad=1280:720:(ow-iw)/2:(oh-ih)/2,setsar=1[1p];
[0p][1p]xfade=transition=fade:duration=1:offset=5.485[1x];
[a1][a2]amix=inputs=2[aout]" -map [1x] -map [aout] _out.mp4 -y 2>&1

Combine two ffmpeg commands (segment and still photo)

is it possible to combine this command
ffmpeg -i video.mp4 -map 0:s:0? -c copy -movflags empty_moov+default_base_moof+frag_keyframe -f segment output%03d.mp4
with a command that can take a still from the first segment
ffmpeg -ss 00:00:00.00 -i output001.mp4 -vframes 1 -q:v 2 still.jpg"

Append the second command to the first:
ffmpeg -i video.mp4 -map 0:s:0? -c copy -movflags empty_moov+default_base_moof+frag_keyframe -f segment output%03d.mp4 -frames:v 1 -q:v 2 still.jpg

ffmpeg concat video and image issue

I have a video it's 190 seconds long.
I want to show a part of the video with audio and a watermark (from 28th second to 154th second)
and then the video fades out, and then show an image for 5 seconds at the end of the video.
everything was working fine until i added concat and endpic.jpg
Here is the script it wrote but it's not working. It's really driving me crazy.
ffmpeg -y -ss 28 -i input.mp4 -loop 1 -i watermark.png -loop 1 -t 5 -i endpic.jpg -f lavfi -t 5 -i anullsrc -filter_complex "[1]fade=in:st=3:d=1:alpha=1,fade=out:st=20:d=1:alpha=1[w]; [0][w]overlay=main_w-overlay_w-10:main_h-overlay_h-10[sonh];[sonh]fade=out:st=154:d=1[sonhh];[sonhh:v][sonhh:a][2:v][3:a]concat=n=2:v=1:a=1[v][a]" -t 155 -map "[v]" -map "[a]" output.mp4

Use
ffmpeg -y -ss 28 -to 154 -i input.mp4 -loop 1 -t 22 -i watermark.png -loop 1 -t 5 -i endpic.jpg -f lavfi -t 5 -i anullsrc -filter_complex "[1]fade=in:st=3:d=1:alpha=1,fade=out:st=20:d=1:alpha=1[w]; [0][w]overlay=main_w-overlay_w-10:main_h-overlay_h-10,fade=out:st=154:d=1[sonhh];[sonhh][0:a][2:v][3:a]concat=n=2:v=1:a=1[v][a]" -t 155 -map "[v]" -map "[a]" output.mp4
If you don't limit the input duration, ffmpeg will feed till 190s of the input, and due to -t 155, the output will never get to the end of the input and the start of endpic.
Linklabels assigned within a filtergraph don't represent the original inputs so [sonhh:v][sonhh:a] isn't valid. The input audio remains [0:a].
Input -to was added a few months ago, so ensure you're using a recent build of ffmpeg.

FFmpeg - combine 2 commands

I have 2 commands as listed below.
Add intro image to a video
ffmpeg -y -loop 1 -framerate 10 -t 3 -i intro.png -i video.mp4 -filter_complex "[0:0] [1:0] concat=n=2:v=1:a=0" -c:v libx264 -crf 23 videoWithIntro.mp4
Add watermark to video
ffmpeg -y -i video.mp4 -i watermark_color.png -filter_complex "overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2" videoWithWatermark.mp4
I was wondering is it possible to combine these into the 1 command?

Use
ffmpeg -y -loop 1 -framerate 10 -t 3 -i intro.png -i video.mp4 -i watermark_color.png -filter_complex "[0][1]concat=n=2:v=1:a=0[v];[v][2]overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2" videoWithWatermark.mp4
I assume your videos don't have audio, else use
ffmpeg -y -loop 1 -framerate 10 -t 3 -i intro.png -i video.mp4 -i watermark_color.png -f lavfi -t 3 -i anullsrc -filter_complex "[0][1]concat=n=2:v=1:a=0[v];[v][2]overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2;[3][1]concat=n=2:v=0:a=1" videoWithWatermark.mp4

The final command to get this working correctly is as follows
ffmpeg -y -loop 1 -framerate 25 -t 3 -i 1920x1080_intro.png -i DSC_0002.MOV -i watermark_color.png -report -an -filter_complex "[1][2]overlay=x=(main_w-overlay_w)/2:y=(main_h-overlay_h)/2,setsar=1[v];[0]setsar=1[pre];[pre][v]concat=n=2:v=1:a=0" ../testing/videoWithIntroAndWatermark.mp4

Ffmpeg show an image for multiple seconds before a video without re-encoding

I've been looking all around for this. Problem is that most google searches end up with being about creating a video from solely PNG files.
I've found this command which does the job :
ffmpeg -y -loop 1 -framerate 60 -t 5 -i firstimage.jpg -t 5 -f lavfi -i aevalsrc=0 -loop 1 -framerate 60 -t 5 -i secondimage.png -t 5 -f lavfi -i aevalsrc=0 -loop 1 -framerate 60 -t 5 -i thirdimage.png -t 5 -f lavfi -i aevalsrc=0 -i "shadowPlayVid.mp4" -filter_complex "[0:0][1:0][2:0][3:0][4:0][5:0][6:0][6:1] concat=n=4:v=1:a=1 [v] [a]" -map [v] -map [a] output.mp4 >> log_file1.txt 2>&1
But it seems to reencode the whole video, the input video is H.264 without CFR, but it seems to me that putting just some images before the video shouldn't take too long.
Because it ends up encoding the whole thing, this takes about 2 hours with a video of 30 minutes on a strong computer, while I feel like without encoding this should be able to be done much quicker. How do I make sure it doesn't re-encode while maintaining every image showing for 5 seconds first?

Generate your playervid.mp4 via
ffmpeg -y -loop 1 -framerate 60 -t 5 -i sample-out3.jpg -f lavfi -t 5 -i aevalsrc=0 -vf settb=1/60000 -video_track_timescale 60000 -c:v libx264 -pix_fmt yuv420p playervid.mp4

How do I add 2 more pictures to this ffmpeg slideshow?

This is the command I use to make the slideshow with ffmpeg:

I would like to add 2 more pictures that lasts 600 seconds each.
Could you please help me?

Well, why don't you experiment manipulating your current command? everything is there. According to your approach you can achieve this as follows.
ffmpeg -y -i audio.wav -framerate 1/4 -t 60 -loop 1 -i first.png -framerate 1/4 -t 600 -loop 1 -i Test.png -framerate 1/4 -t 600 -loop 1 -i test-ceinture-running-flip-belt.png -framerate 1/4 -t 600 -loop 1 -i Wikimedia_Outreach_test_logo.png -framerate 1/4 -t 600 -loop 1 -i new_image_1.png -framerate 1/4 -t 600 -loop 1 -i new_image_2.png -filter_complex "

[2:v]scale=iw*min(1280/iw\,720/ih):ih*min(1280/iw\,720/ih),pad=1280:720:0+(1280-iw*min(1280/iw\,720/ih))/2:0+(720-ih*min(1280/iw\,720/ih))/2 [v1];

But the way you have done this is not efficient. You may need to reed the relevant documentation first. You can rename the image files with common settings like -framerate 1/4 -t 600 to something like img%03d.png. It will help you to reduce the command length as well as the performance aspect at the execution.
Hope this helps!
