AntCu, thanks for the fast answers!
As my computer is "only" an old 1,86GHz Core 2 Duo, I think Huffyuv is the best codec to use with it, but I'm open to Lagarith - I know it compress more, must do some tests, when the new primary HD will be installed.
Using Huffyuv, the color space will be YUY2, as Huffyuv's default color space is YCbCr and laserdisc's is YUV, so all of them are 4:2:2.
But, why resize at 768x576 if I plan to do DVD or AVCHD?!? I know its PAR is 1:1, but it is off standard...
By the way, crop and resize in one instance, or crop first and resize after, operating with a codec like Huffyuv, is the same, as the codec is lossless... isn't that right?
About distribution: I just finished to calculate the size taken for each trilogy, and if my calculation is right it will be about 240GB using Huffyhuv!!! With my poor ADSL it will take forever to upload the files! Also, with "only" 1TB of hard disk dedicated space, I could capture (if I'm lucky) at best four trilogies... maybe it's better to capture one episode at time - so I could store up to 12 captures - not that I need all of them, but considering versions, copies and laserdiscs, I think I could reach 9 captures easily... then, after that, I could "mix" them and store as long term only the result. And restart with the next episode!
For your median script: I'll test it after the first captures are done. But did you tried the TOOT script? Yes, I know I must align spatially and temporally the captures, I've done it before - with A LOT of work, if I remember well ;-)
...using the TOOT script, the results were good.. but I used only three captures. With more, like nine captures, I could TOOT 1,2,3 then TOOT 4,5,6 then TOOT 7,8,9 and finally TOOT the results... at the end, the picture will be as clean as the best laserdisc picture could be, dropouts free!
I used here TOOT as example, but I'm open to use another script, like yours. If someone else has good experience with multiple captures, please post your script!
Antcu, can I count on your help if (when) needed, for what concerns AviSynth and/or VirtualDub scripts and settings?
