slide使用ImageMagick工具和ffmpeg擦除效果 [英] slide Wipe effects with ImageMagick tool and ffmpeg
问题描述
我必须做四个幻灯片效果,名为'擦拭','擦拭','擦拭','擦拭左'。像每种类型的两个图像的幕布。我认为用'转换'来裁剪图像是可能的
I have to do a four slide effects named 'Wipe Up', 'Wipe Down', 'Wipe Right', 'Wipe Left'. Like curtain of two images for each type. I think it can be possible with cropping of images with 'convert'
convert 01.jpg -crop 1920x5 output_%03d.jpg
我可以获得一系列图像并同时合成第二张图片(我不知道什么)知道..)然后我可以使用ffmpeg从这一系列图像构建视频:
where i can get sequence of images and compose at same time to the second image(What I don't know..) And then I can build video from this sequence of images with ffmpeg:
ffmpeg -i output_%03d.jpg out.mp4
也许有人可以在我裁剪的同时帮助我合成图像?感谢您的任何建议!
Maybe someone can help me with compossing of images in the same time when I croping? Thanks for any suggestions!
PS:所有图片都有固定的尺寸:1920x1080
PS: all images have fixed dimensions: 1920x1080
推荐答案
您可以使用ImageMagick的 MIFF
格式(多图像文件格式)将多个裁剪图像流发送到另一个ImageMagick调用,将它们放在视频中序列。因此,假设您从这开始:
You could use ImageMagick's MIFF
format (Multiple Image File Format) to send a stream of multiple, cropped images to another invocation of ImageMagick to put them together in a video sequence. So assuming you start with this:
并且这样做了
convert input.png -crop 1920x10 miff:- | convert - -loop 0 out.gif
你会得到这个
