Hello,

This is what it means. Other than that I don't know.

The older versions of virtualdub (under 1.5x) have an excellent guide under the help menu/content/advanced topics/frameserving which explains it's use with vdub.

Well done. That's how I learned it a long time ago.

I do not doubt thatt Avery gave a good answer to it in vdub 1.5, but for lazy SOBs like myself, the short answer is that before you can encode a video that has been compressed (DVDs are compressed with MPEG2 for example) you need to decompress it into an uncompressed state. One way to do this is to convert the whole video to an uncompressed video stream then compress with your codec of choice. The downside of this is that it requires what is scientifically known as "a whole lotta space" to do.

The other option is to just uncompress a few frames at a time as you encode the video stream. Then discard the uncompressed frames after you have encoded them into your new video stream. This is frameserving.

Somehow and don't ask me why but I understood that I wonder if efiste2 did?
I still like the explanation in vdub 1.4x better. :P
