ffmpeg: how to concatenate files that have different resolutions?

[marcorocchini]

Hi, but I'm a C*T

please I wonder if there is a way to concatenate with ffmpeg video files that have different resolution or bitrate ecc.. according to a target resolution bitrate ec...

for example:

file1.MXF = 1920x1080 25fps interlace

file2.MXF = 1440X1080 30fps progressive

I need to tell to fffmpeg that the output have to be 1920x1080 25 fps interlace, so that eventually it have to treat all the clip that are not in this format to match the target profile.

Is it possibile? thanks

You probably need to build a complex filter graph that scales each input and then feeds them into the concat filter.
