@neuron2
Please forgive me if I misunderstood your answer; but I think he is asking for the avisynth function
in text-overlay.cpp; that if I'm not wrong it is not still YV12 implemented.

I stand corrected. Thank you, ARDA. Sorry, jonny.

[jonny]

Yes, what ARDA says is correct ;)
I've done some research but i've only find a post of Marc FD:

I know Marc have trashed his compiler :), so i'd like to know if someone is going to implement this function for YV12.

The current code is too complex for me to dive into :(

I had hoped dividee had some time to update it - if anyone else is willing to dive in - feel free!

(but it is on the TO-DO-list of course - just far below bug-fixes).

I have a suggestion for the Compare function.
I use this function mainly for generating the log file, opening the script via VDub and encoding using "direct stream copy" (OT: is there a better method?)
In this case, could be possible to output a really small clip (for example 32x32 black clip), this should speed up the process.

It's only a suggestion, let me know what you think.
Thanks
jonny

PS: i'm thinking to develop a small gui for the PSNR calculation between 2 clip, this is why i'm asking all this things.

Just use Xvid, and select "Null - test speed" as compression method. This will just dump your data and output nothing for the AVI file.

Thank you very much for the suggestion.
