Transition Effects Not Working with FFmpeg Command: Solution
If you're trying to bring transition effects when joining videos and getting an output video without proper transition effects, you're not alone. This article will provide you with a detailed context topic and a solution to the problem of transition effects not working with the FFmpeg command.
Understanding Transition Effects
Transition effects are visual effects that are used to smoothly move from one scene to another. They help to create a more engaging and professional-looking video. FFmpeg is a powerful tool that can be used to join videos, but sometimes the transition effects don't work as expected.
The Problem
The problem occurs when you try to join videos with transition effects using the FFmpeg command, but the output video doesn't have the expected transition effects. The video length remains the same, but the transition effects are missing.
The Solution
The solution to this problem is to use the -filter_complex option in the FFmpeg command. This option allows you to apply complex filters to your video, including transition effects. Here's an example of how to use the -filter_complex option to join two videos with a fade transition effect:
ffmpeg -i input1.mp4 -i input2.mp4 -filter\_complex "[0:v]format=yuv420p,fade=t=out:st=10:d=3:alpha=1[v0]; [1:v]format=yuv420p[v1]; [v0][v1]overlay[outv]" -map "[outv]" -map 0:a output.mp4
In this example, the first video (input1.mp4) fades out for 3 seconds starting at 10 seconds, and then the second video (input2.mp4) is overlaid on top of it. You can adjust the transition effect by changing the values of the fade filter.
