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.

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];

-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"

[a1][a2]amix=inputs=2[aout]" -map [1x] -map [aout] _out.mp4 -y 2>&1
ffmpeg -i foo.mp4 -filter_complex "fade=d=0.5, reverse, fade=d=0.5, reverse" output.mp4
can be used to fade in and out foo.mp4 video. (we do not care about audio). According to https://video.stackexchange.com/questions/19867/how-to-fade-in-out-a-video-audio-clip-with-unknown-duration
It's good but only works in the simple situation of 1 input video, and 1 output. Now, how can I apply the fade in and out effect in the following more complex situation? I'm trying to concat a.jpg (a picture) with bar.mp4. I want only the bar.mp4 portion to fade in and out.
ffmpeg -loop 1 -t 2 -framerate 1 -i a.jpg -f lavfi -t 2 -i anullsrc -r 24 -i bar.mp4 -filter_complex "[0][1][2:v][2:a] concat=n=2:v=1:a=1 [vpre][a];[vpre]fps=24[v]" -map "[v]" -map "[a]" out.mp4 -y
Of course, I could first create a temporary temp.mp4 from bar.mp4 by running the first command, then input temp.mp4 in my second command. This involves an extra step and extra encoding. Could anyone help fix the commands or suggest something even better?
Use
ffmpeg -loop 1 -t 2 -framerate 24 -i a.jpg -f lavfi -t 2 -i anullsrc -r 24 -i bar.mp4 -filter_complex "[2:v]fade=d=0.5, reverse, fade=d=0.5, reverse[v2];[0][1][v2][2:a] concat=n=2:v=1:a=1 [v][a]" -map "[v]" -map "[a]" out.mp4 -y
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
I am using this command line to add a five second image on end of video:
ffmpeg -i "f:\output\input.mov" -loop 1 -t 5 -i "f:\output\taff.jpg" -f lavfi -t 5 -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]" f:\output\output.mp4
It works great, but sometimes I want to cut the video and then add the five seconds. So, make a 120 second video 110 seconds, then add the 5 second ending.
Possibly in one command line? I've tried to break it into two, by starting with cutting the video, but then I get an "Unable to parse option value "-1" pixel format" error if I try to re-encode the video I cut with ffmpeg using this:
ffmpeg -i f:\output\input.mov -vcodec copy -acodec copy -ss 00:00:00.000 -t 00:01:50.000 f:\output\output.mov
That output video will then give an error if I try to run the first command line against it.
All feedback appreciated on shortening a video, and then adding ending.
Cheers!

Use
ffmpeg -t 110 -i "f:\output\input.mov"
-loop 1 -t 5 -i "f:\output\taff.jpg"
-f lavfi -t 5 -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]" f:\output\output.mp4
With scale2ref, it should be
ffmpeg -t 110 -i "f:\output\input.mov"
-loop 1 -t 5 -i "f:\output\taff.jpg"
-f lavfi -t 5 -i anullsrc
-filter_complex "[1][0]scale2ref[2nd][ref];[ref][0:a][2nd][2:a]concat=n=2:v=1:a=1[v][a]"
-c:v libx264 -c:a aac -strict -2 -map "[v]" -map "[a]" f:\output\output.mp4
If the image has a different aspect ratio, use
ffmpeg -t 110 -i "f:\output\input.mov"
-loop 1 -t 5 -i "f:\output\taff.jpg"
-f lavfi -t 5 -i anullsrc
-filter_complex "[0]split[base][full];[base]trim=0:5,drawbox=t=fill[base];[1][base]scale2ref='if(lt(mdar,dar),oh*mdar/sar,iw)':'if(lt(mdar,dar),ih,ow*sar/mdar)'[2nd][base];[base][2nd]overlay='(W-w)/2':'(H-h)/2'[padded];[full][0:a][padded][2:a]concat=n=2:v=1:a=1[v][a]"
-c:v libx264 -c:a aac -strict -2 -map "[v]" -map "[a]" f:\output\output.mp4
This last command requires ffmpeg version >= 3.4
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
