Maybe it's a dump question, but i'm not a programmer, so i can't judge this. OK, here's the Qustion:

There are AVISynth-Scripts for analysing the Video (looking vor high and low motion scenes). But ist there any chance to do something like the following:

Looking for high and low motion scenes and export the Frame-Numbers/Frame-Count to an extra File? It might be usefull for using TMPGEncs-MVBR-Mode to increase the encoding-quality.

Wow, hard stuff to read for a non programmer like me. :eek:
And up to now, i've only done the easy things with AVISynth.
Guess i have a lot to learn now (hey, looks more complicatet than all those DCT-Stuff i was able to manage ;) ).

Thanks, this may help a little. But it's only the half way. It's good to know the percentage of high- medium and low motion. But what i really need is to know, which part of the Video exactly is in one of those conditions.

Like this Style:
Frames 1000 - 1400 = Low
Frames 1401 - 1850 = High
...
....

and so on.

With this Informations, i can do what i call the "Super CQ-Mode" with TMPGEnc. I have done this a couple of times by Hand - watching the Video and notice the Frame-Numbers - but on longer Videos, this is true pain. :rolleyes:

It could be possible to use QMF

with the frame_number variable I mentioned on my other post.

I don't have the time to test it this week, but my idea is to use the CALL command to write the framenumber to three different files:

Low Motion -> low.txt

and so on.

@bilu

Sound's good. I will do my own research on AVISynth, but have not enough experience with it yet. OK, i'm not an absolute Beginner in using AVISynth, but far far away from being a professional. Learning to use AVISynth AND doing such comblicated things is not easy.
It would be nice, to send me a short PM if you find out, how to do that to prevent me from missing a Posting about that.

Thanks in advance,
Kika
