Preferred name and image resolution for BIF files

Question

I was wondering if there was a preferred file name and/or image resolution to use when creating BIF files for trick mode support. The developer guide simply states HD and SD versions. While on the same topic, is there a recommended time interval for the images? 5 seconds between captures? 10 seconds>

Thanks!

I am doing SD at 240x180 and HD at 320x240 15 seconds apart.

You can specify how far apart you want in time. File name should be something you can associate with the video name in case you forget what it is later.

Section 3.3 of the Encoding Guide talks about BIF creation.

The SD frames should have a width of 240 and the HD frames should have a width of 320. Their height should be specified to coincide with their aspect ratio.

In section 3.3 is there a way to fix the offset in windows cmd? I use ffmpeg and biftool here on Windows XP. Is there an equivelant to run in Windows versus linux?

Linux
% j=00000000.jpg; for i in *; do mv ${i} ${j}; j=${i}; done;

Windows ?
Thanks,

If you download "microsoft expression" it can batch rename image files for you.

It's real easy to use.

I'm sure there are other ways, just that was the first thing I used that I had a need for the feature...
