Hi,

I am very new to video editing and just get some general knowledge of the subject. I am trying to find info on asf. From searching this forum, I read what asf is (https://forum.videohelp.com/topic138899.html). It looks like asf is not seekable until the whole movie is downloaded.

There were time when I watch video on a website, I can kinda fast forward or rewind a video (without the whole video being downloaded. In the status bar, I see "buffering") For that kind of video, is it asf? If not, what format is that?

I also joined some asf files together using asfbin. Some options in that app include -sionly (simple indexing) and -forceindex (advancing indexing) What is the diff between the 2? Looking at the author's website (http://www.radioactivepages.com/index.php?docid=asfbindet&lang=en&section=software) I really can't tell the diff btw the 2.

Thanks in advance
