| Aug 2, 2018 at 11:58 | comment | added | Shubham AgaRwal | @7sega7 add scale=1280:720,setdar=16/9 for each image to scale and maintain aspect ratio | |
| Aug 2, 2018 at 11:52 | comment | added | Shubham AgaRwal | @LordNeckbeard Thanks for the great answer once again. we can add setdar=16/9 to prevent aspect ratio related issues. Can you suggest me a solution to map audio stream as well in the same script i am getting weird responses each time i am mapping it via complex filter | |

removed ugly ffmpeg crossfade example. will add a better one later.

| Apr 26, 2017 at 1:37 | comment | added | llogan | @7sega7 I'd have to see your command and console output to see what exactly is going on. You can use a pastebin site and provide the link here. | |
| Apr 24, 2017 at 15:01 | comment | added | 7sega7 | @LordNeckbeard How can I do it withouth the error from scale is not the same or SAR is not the same? There is a parameter that permit create a video with images with different scales and SAR? | |

Spoke too soon on the ffmpeg crossfade approach. It works for the original 1 sec / 0.5 sec, but when I try to do 2 sec / 0.5, it gives me image times of 2, 3.5, and 3.5 sec for the following 3 image merge: /usr/local/bin/ffmpeg -y -loop 1 -t 2 -i file1.png -loop 1 -t 2 -i file2.png -loop 1 -t 2 -i file3.png -filter_complex "[1:v][0:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b1v]; [2:v][1:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b2v]; [0:v][b1v][1:v][b2v][2:v]concat=n=5:v=1:a=0,format=yuv420p[v]" -map "[v]" out.mp4 ideas?

The ffmpeg approach is working nicely for me; thanks! One tip for newcomers to the page; in the concat=n=9 part of the command, the 9 comes from the 5 images in the example + 4 transitions between the images. If you're handling a different number of images, you'll need to adjust that accordingly.

| Sep 27, 2016 at 14:10 | comment | added | jrkt | @LordNeckbeard I've created a question asking the above about combining the blend and zoompan filters into one command superuser.com/questions/1128563/…. I could really use some help. | |
| Sep 26, 2016 at 17:35 | comment | added | jrkt | Thanks for replying. I am trying to include a specific zoompan filter for each image so I can apply that filter at the same time. How would I also include that in the command above that uses the blend filter? Where would I put it? One example of a zoompan I'm trying to include is: zoompan=z='min(zoom+0.0005,1.5)':x='if(gte(zoom,1.5),x,x-1)':y='y' | |
| Sep 23, 2016 at 14:06 | comment | added | jrkt | I tried adding that and it still won't work.. I have opened a new question if you wouldn't mind looking at it @LordNeckbeard? superuser.com/questions/1127542/… | |
| Sep 23, 2016 at 2:17 | comment | added | llogan |
@JonStevens [0:v]setsar=1[sar0];[1:v][sar0]blend...
|
|
| Sep 22, 2016 at 19:22 | comment | added | jrkt | How would you implement the setting of the SAR and DAR within the filter_complex? For example I need to add the additional filter "setsar=sar=1/1,setdar=dar=16/9" to this line in the filter_complex: "[1:v][0:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b1v];". Where would I place this additional filter? I have tried to place it after the "[0:v]" and I get the ffmpeg error, "Too many inputs specified for the "setsar" filter." | |

simplify and add melt example
|
| Aug 25, 2016 at 22:59 | comment | added | Web User | @LordNeckbeard sorry I am unfamiliar with melt. Can you point me to it? | |
| Aug 23, 2016 at 5:31 | comment | added | llogan |
@WebUser Transitions are probably going to be easier using melt.

| Aug 17, 2016 at 17:37 | comment | added | Web User | @LordNeckbeard I need to combine a set of images, video clips and an audio track to create a single video file (preferably ogg, but that is less relevant at this point). In addition, I need to create some transition effects between adjacent images. Is there any way to script this whole task using ffmpeg and/or other command line tools? The goal is to automate the task via a command line interface. | |
| Aug 7, 2016 at 13:12 | comment | added | Nisarg | @LordNeckbeard Yea thats what i did :) but it still takes 1 to 2 mintues, can we still reduce this i mean by managing inputs ? | |
| Aug 6, 2016 at 16:06 | comment | added | llogan |
@Nisarg That does not appear to be the complete output and I'm not sure what command it is from of the two you displayed earlier. Anyway, try adding -preset ultrafast.

| Aug 6, 2016 at 8:51 | comment | added | Nisarg | @LordNeckbeard Yes Please check this | |
| Aug 6, 2016 at 4:30 | comment | added | Nisarg | @LordNeckbeard Yea sure please look at this | |
| Aug 5, 2016 at 12:42 | comment | added | Nisarg | @LordNeckbeard Its taking too much time to generate video, can we reduce it ? | |
| May 19, 2016 at 8:27 | comment | added | cincplug |
@LordNeckbeard, thanks for this answer, I used it for another example. Have I understood well that number following -t in -loop 1 -t 1 -i 001.png defines the duration of individual frames, and that numbers following T/ within filter_complex block defines the transition's duration? And is the frame duration in this example counted including transition's duration or not?

@jankigadhiya Make a new question. Include your full ffmpeg command and the complete console/log output.
