Autodesk Cleaner: adding letterbox black bars ("widescreen matte"

[sybariten]

Hi,
would you happen to know if its possible to add letterbox bars to a widescreen videosource, in AutoDesk Cleaner?
I have been looking through the manuals but not found anything. I also know that they market the product with the feature "letterbox removal", but as you understand i need to do the exact opposite and i cant find any information on it. I dont find any functions for it in the program.

We need to go from a 1024 x 576 video source to a normal PAL image, i suppose thats 720 576 ... (so we will also downscale). Not the best solution but we are gonna do this for a limited time.

What is the output for ? If it is for DVD, then resize to 720 x 576 and encode as 16:9 and it will display correctly. If you need a 4:3 letterboxed image then resize to 720 x 448 and add borders. Don't know if cleaner can do this directly (haven't used it in years), but avisynth can do this very easily, and cleaner should then be able to encode from the avs file.

A simple script would look like this

DirectShowSource("path to your video/video filename")
Lanczos4Resize(720,448,5,0,1013,576)
AddBorders(0,64,0,64)
#Trim(0,5450).FadeOut(150)
ConvertToYUY2() # For VirtualDub or CCE

No the output isnt for DVD, i'd say its more for some treatment before being incorporated in a broadcast... and "the people on the other side" have specifically asked for a 4:3 letterboxed version.

Your avisynth approach was very interesting, I never thought of that. I dont think i'll be allowed to install extra software here though, which is why i asked about cleaner only. But i'll keep it in mind if things change. Thanks!
