Hi All,
I am using the filters to put text in the top/bottom left and logos in
the top/bottom right of my converted videos. It has been working
perfectly for many months.
Here is my command:
/usr/local/bin/ffmpeg -i 4384.mts -vf
"movie=/home/bigwayvideos/processing/bottom_right_watermark.png
[logo];movie=/home/bigwayvideos/processing/top_right_watermark.png
[logo2];[in][logo] overlay=W-w-8:H-h-8 [in+logo];[in+logo][logo2]
overlay=W-w-8:8 [in+logo2]; [in+logo2]

The [old] output looked like this:

Notice the size of the logo in top right/bottom right.
About 3 weeks ago I upgraded my ffmpeg (using the steps outlined in this
thread) and now when I process the videos my logos are super small.
The new output looks like this:
http://legacy.skydivingphotography.com/new.png
Note the [small] size of the logos in top/bottom right.
The video input is the same size and so are the logos themselves; the
only thing different is the ffmpeg I am using.
Does anyone know if I need to pass any additional/new flags into ffmpeg
or what I need to do to get them the same size they were?
As always, thanks for your time
-Rob
