Firstly we concatenate everything and pipe result to v a (see filtergraph syntax docs - its output from concat filter). FFmpeg GUI is a very neat application that converts virtually any video format to any other. ffmpeg -i d:1.mp4 -i d:2.mp4 -filtercomplex 'concatn2:v1:a1 v a vscale320:200 v2' -map ' v2' -map ' a' d:3.mp4.
#Ffmpeg vstack different size plus
Currently building all GPLv3 codecs plus many external libraries. If I recall, this means the videos have to be the same height and have the same encoding. FFmpeg builds for windows win32 and windows win64.
One thing about using hstack taken from the ffmpeg filter documentation:Īll streams must be of same pixel format and of same height Setting shortest=1 will make it the length of the shortest video stream instead.Īfter that, we just map the video stream created from hstack to the output file and you're good to go. I can combine same size videos with the command: ffmpeg -i 1.mp4 -i 2.mp4 -filtercomplex ' 0:vscale520:-1 v0 1:vscale520:-1 v1 v0 v1. I first crop them to 720圆40 (crop 320px from top and 320px from bottom), then combine vertically. By default, it will be the length of the longest video stream. I need to combine 2 video that has 720x1280 resolution. The inputs option indicates how many video streams are being used as inputs (defaults to 2) and the shortest option indicates how long the output video stream will be. We are taking the video streams from the two inputs and passing them into the hstack filter. You'll see we are passing in two videos as inputs with the -i option, video1.mp4 and video2.mp4.
