I support the percentage method (I suggested 50%, but 10% is better...), and the use of a 'keyframe' to speed up the Thumbnails creation.

Me too.

Since we can use %, I think option for this is not needed at all.

What about this? I think this may be a reason for slow WMV th. creation.

INI entry ?

:) Hello Pierre!

- I guess that this percent-value could be stated as an INI variable entry, so advanced users could adjust it “by hand” following their own needs…

:?: What do you think ?

Another app gives you the option to skip over the initial black frames and also allows you to set the black threshold percentage (in case it's not completely black black).

This is generally quite succesful, apart from when there is some writing on these black frames. It also allows you to limit the maximum time spent on each thumbnail before no thumbnail will be created, in case a lot of the initial part of the movie is black.

I think this feature, along with the ability to specify either a percentage, or an absolute time from where the thumbnail should be created gives the maximum amount of flexibility.

That black frame might also be a gap between two other frames which would be unavoidable.

I have 1st black frame also for some mpg, xvid and DivX 3, 4, 5 files.

I'm sure the first frame is used for those files, since I have tested files with non black 1st frame in VirtualDub and that frame is used as thumbnail in xnview.

For some DivX 5 files, correct frame (10%) is used as thumbnail (probably other 5.x version).

I believe in you, but several avi (divX) files ignore this setting - I'm 100% sure about it - 1st frame is used for those files.

I think some other files (mov, mpg) also ignore that setting.

I'll try to upload some (divX) files to http://rapidshare.de/ . I'll let you know per PM.

I think all mov files ignore that setting, please check it out.
