合并多个 mp4 视频和图像
combine multiple mp4 videos and images
所以我有一个名为 *.png
的图像文件夹,1/20 和一个名为 *.mp4
的 mp4 文件夹。
我想按以下顺序制作视频:
1.png
持续 3 秒
1.mp4
2.png
持续 3 秒
3.mp4
- 等等
有没有办法让每个 png 显示 3 秒,然后使用 ffmpeg
显示相应的 mp4?我知道我可以使用此命令将每张图片单独转换为 3 秒视频,帧率差异将是一个问题(1/3 对 60),但我对命令行视频编辑不是很有经验:
ffmpeg -r 1/3 -i 1.png -vcodec mpeg4 1_intro.mp4
