[FFmpeg-user] How to change -vcodec tiff resolution?

[Eric Hollis]

Hi.  First, thanks for the help yesterday re how to grab images from video
(vfwcap) for a 16mm film archiving project. This works for me:

ffmpeg.exe -r 1 -t 1 -rtbufsize 10000000 -f vfwcap -s hd720 -i 0 -vframes 1
-an -vcodec tiff test%d.tif

However, I have one last problem with this.  The tif image that results is
72dpi, and I want it to be 96dpi or higher. Could someone point me in the
right direction?
