如何使用ffmpeg和imagemagick为视频添加顶部和底部框架 [英] How to add top and bottom frame to a video using ffmpeg and imagemagick

问题描述

我正在尝试为视频添加顶部和底部部分，就像我们为图像模因一样。我正在使用ffmpeg和imagemagick，但没有内置选项来执行此任务。假设我有一个视频，我需要将这样的标题添加到整个视频中。我怎样才能实现这一目标？

和 drawtext 。在此示例中， pad 向顶部添加50个像素，向底部添加50个像素，然后每行添加两个 drawtext 实例。

  ffmpeg -i input -filter_complex \ 
[0：v] pad = iw：ih + 100：0 :( oh-ih）/ 2：颜色= white，\ 
 drawtext = text ='ONE DOES NOT SIMPLY'：fontfile = / path / to / impact.ttf：fontsize = 24：x =（w-tw）/ 2：y =（50- th）/ 2，\ 
 drawtext = text ='STOP ME FROM FILTERING'：fontfile = / path / to / impact.ttf：fontsize = 24：x =（w-tw）/ 2：y = h -25-（th / 2）\ 
输出
  

I'm trying to add a top and bottom section to a video like we do for image memes. I'm using ffmpeg and imagemagick but there is no inbuilt option to do this task. Let's say i have a video and I need to add the caption like this to the whole video. How can i achieve this?

解决方案

From what I can tell something like this is what you're looking for:

Using pad and drawtext. In this example pad adds 50 pixels to the top and 50 pixels to the bottom, then two drawtext instances place each line.

ffmpeg -i input -filter_complex \
"[0:v]pad=iw:ih+100:0:(oh-ih)/2:color=white, \
 drawtext=text='ONE DOES NOT SIMPLY':fontfile=/path/to/impact.ttf:fontsize=24:x=(w-tw)/2:y=(50-th)/2, \
 drawtext=text='STOP ME FROM FILTERING':fontfile=/path/to/impact.ttf:fontsize=24:x=(w-tw)/2:y=h-25-(th/2)" \
output
