Life would be great if there were an automatic way to detect scenes and save them as separate AVIs. I saw a post once that suggested AVISynth might contain that capability, but the program is overwhelming. Has anyone figured out a way to do this?

Someone might be mistaken; I don't recall AVISynth having any capability like that. AFAIK the only way to do this is to do it manually.

I just discovered Stoik's freeware Video Converter.
http://www.stoik.com/downloads/downloads_frm.htm
I am having some luck with getting automatic scene detection/separation, but still have to work on it.
First try, it only detected the first shot transition.
Then I twiddled the threshold values in the .ini file. Right now I'm at:
HueThreshold=1
SatThreshold=0
ValThreshold=0.4
DisThreshold=0.4
which produced a few false hits in a capture with about 10 shots, and missed one. The sequence was shot in a garden, so there was green everywhere. It would probably perform better on better-defined changes.
(I also used VirtualDub first to clean up around the transitions, because I had some tripod shake as I shut off the camera. Real cheap tripod. )
I also got trashed audio in two of the clips (using MP3). I don't understand why it was only bad on two, and am going to experiment some more with different or no compression.
All in all, I'm hopeful.

Why don't you simply try "scenalyzer" ?? |

I looked up Scenalyzer, It looks like it only works with DV video, the latest version ScenalyzerLive works with 1394 input cards. It sounds cool, but I don't use DV. Is there a version that works with Open DML AVIs with any codec? |

VirtualDub 1.4.9.2 VCR + SYNC at
http://www.virtualdub.net/
will solve this. The probelms is that there is very little documentation and even that's partly in German. |
