Letter box / Crop to resize ?

Post by kehn » Sat Jun 27, 2009 12:48 pm

Hi bros,

How can I set up "Picture" to get the result like the capture below:
(with black letter box to add subtitles separated from pictures)

Every times I tried, Mediacoder Crop - Cropper kind of stuck, could not set the right size.

Thanks!

Here is an example for you to follow.

In this image you can see my source video is 640 x 272.

Open the advanced setting dialog.

Look for "Video Filters"

You need to set "Enabled" = True

Then play with the "Height" and "Y Position"

In my example I added 48 lines to the frame height, then moved the video up 48 lines to align the original video frame (640x272) with my new frame (640x320)
You will get a better picture if your output frame is a multiple of 16 (or at least a multiple of 4).

I have never tried this before but I would think that you can then line up the subtitles like you wish
