Using WinFF and Virtual Dub to Encode Videos for the Sansa c200 line

The following text was copied from a post on the forums at the following address: http://forums.rockbox.org/index.php?topic=18617.0

Me being a total newb to RockBox, after having read and searched all the info, was still having
problems trying to convert a 1-hour documentary that I like to carry with me to show others.
It was in an obscure codec (still on my machine) and I found out it even had some kind of
audio offset that WinFF didn't like.

I thought some of you might like to know how I managed to salvage that video and make it play on my C250.

I first converted it into the required 132x80 size needed using VirtualDub (http://www.virtualdub.org/)
with more standard video and audio codecs, and also used the "Resize" filter (it can keep proportion
and add nice letter-boxing on it all in one). THEN I used that WinFF utility on it. I made 4 new C250
profiles for WinFF. I thought some of you might like this bit of info if you are a total RockBox newb like me.

C240/250 WinFF Profiles:

Preset Name: c200FS
Preset Label: RB Sandisk Sansa c200 4:3
Preset Command Line: -acodec libmp3lame -ab 128 -ar 44100 -vcodec mpeg2video -s 132x80 -b 320kb -strict -1
Output File Extension: mpg
Category: Rockbox

(I used the following on my repaired preformatted video file from VirtualDub.)

One thing that kept throwing me for a loop is that the resulting videos from WinFF in this format
wouldn't play on my machine. Probably from the odd frame size or something. But I put it on my
Sansa C250 and it worked great! Fast forward, rewind, the works. A 1-hour video only came out to
187megs. Putting "Lord of the Rings" on a 4GIG SD card would be a cinch! :-)

Anyway, there's a nice work-around for you wanting videos on your MP3 player. Use VirtualDub to
preformat it in the right size and in codecs that WinFF will be happy with. THEN use WinFF on it. Goes fast and easy.

Thanks again folks for the fun and fine piece of programming!
