Invalid argument
我正在使用的参数:

据我了解，这样做不是应该在乎视频大小吗?
From what I understood is it isn't supposed to care about the video sizes when doing it this way?
推荐答案
对于给定的输入集，您将使用
For the given set of inputs, you would use
-i "E:\Documents\Content Bar\Photo Booth\PhotosDrop\20180416215218.mp4"
-i "E:\Desktop\Videos\Processing\2018-05-15 14-01-16.mp4"
-i "E:\Documents\Content Bar\Photo Booth\PhotosDrop\20180416215218.mp4"
-i "E:\Desktop\Videos\Processing\2018-05-15 14-01-27.mp4"
-i "E:\Documents\Content Bar\Photo Booth\PhotosDrop\20180416215218.mp4"
-i "E:\Documents\Content Bar\Photo Booth\PhotosDrop\20180416215218.mp4"
-i "E:\Desktop\Videos\Processing\2018-05-15 14-01-33.mp4"
-i "E:\Documents\Content Bar\Photo Booth\PhotosDrop\20180416215218.mp4"
-filter_complex "
[1:v]scale=800:600:force_original_aspect_ratio=decrease,pad=800:600:(ow-iw)/2:(oh-ih)/2,setsar=1[1v];
[3:v]scale=800:600:force_original_aspect_ratio=decrease,pad=800:600:(ow-iw)/2:(oh-ih)/2,setsar=1[3v];
[6:v]scale=800:600:force_original_aspect_ratio=decrease,pad=800:600:(ow-iw)/2:(oh-ih)/2,setsar=1[6v];
[0:v] [0:a] [1v] [1:a] [2:v] [2:a] [3v] [3:a] [4:v] [4:a] [5:v] [5:a] [6v] [6:a] concat=n=7:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" "E:\Desktop\Videos\Processing\2018-05-15 14-01-16OUT.mp4"
对于每个720p输入，将视频调整为800X600画布的大小，并将SAR设置为1.
For each of the 720p inputs, the video is resized to a 800X600 canvas and the SAR is set to 1.
(您不使用第8个输入).
(You don't make use of the 8th input).
