You are doing : scale / crop1 / filter /crop2 / expand I say it far better to do scale / crop2 / filters / expand. Period :!: This way your first picture would have been in fact exactly like the second one :banghead: (note : may be the second line need differents crop parameters than the ones in crop2, I don't have the time to think about maths, I just dealing with ideas ;-)) Quote:

With my way you creates the bars AFTER you had put the noise ! In short : try this line and post the screenshot of the result please : Code:
vf=yuvcsp,pullup,softskip,scale=720:360::0:9,crop=672:270:24:0,noise=99th,unsharp=l3x3:0.6,hqdn3d=3:6:2,unsharp=l3x3:-0.7:c3x3:-1.5,expand=704:480 :arrow: You still had borders after the first crop then you added noise (that for sure goes on these borders also); I remove ALL the borders and put noise so there can't have any noise on the borders. note : as I said, you will perhaps cut some picture (or screw the A/R) with the crop value I give here because I didn't take the time to redo the calc. I just take the values of the two crop you have in your second screenshot and "mix" them to do that line. But the idea is still the same. edit: finally I cancel this note. I'm sure of the result. You won't screw anything and will have exactly the same result that you have in your second screenshot :-) I won't add any words before to see the screenshot (try to take the same frame please). Thanks. |
Hi guys,
If you keep on posting like this I'll have to forget this thread or else I'll kill myself laughing :rotf: But on the other hand, and now a bit more seriously, this is very interesting arguments used by karl and phil... :roll: Second thought: keep on with it as I may, as usually, learn something here :wink: Cheers |

Code:
vf=yuvcsp,pullup,softskip,scale=720:360::0:9,crop=672:270:24:0,noise=99th,expand=704:480 Now Karl and I did many test and a diseaster came out! (Thats why Karl stuck on the alternative using a second crop!) Means the final active movie image was totally put wrong on the whole screen. I tried and tried and found it! Theres still a 0 at y which has to be 45!! Thats all ... but you told that it was written down fast by you, so no problem! ;-) And thats the right one: Code:
vf=yuvcsp,pullup,softskip,scale=720:360::0:9,crop=672:270:24:45,noise=99th,expand=704:480 |

Quality is the same, AR is the same, PAR is the same, SPEED is the same. EDIT!!: I do see now what you mean with "first crop" .. as you dont mean crop "has to be first" right?? And I do think in here the thread is TOTALL mixed up :lol: As we first where talking about the first crop or first scale issue ... which waas explained above that theres no difference, ... and then it changed to the "second" crop command to get rid of borders left. I do see it right now -- call it a conclusion: - No problem if first scaled (explane the page before) - BUT the needed cropping to the active pixel area can be done already in the first cropping - like Phil showed - but the using -1,-1 to "center" the cropping ... which avaids a bug in mencoder (if its a bug) :) |

But I wont change the scale/crop to crop/scale as its the same in the way mencalc does as the result is totally the same. So now its only up on to already set the first cropper to a state that in the first cropping ALREADY the useless black original borders will be deleted so that the forthcoming filters will only perform on the active movie pixels. Thats why in the next version of Mencalc (and packshot) there will be 2 chackboxes available (x 2.35:1 and x 1.85:1) and a Y-Axis active movie area input field where manually the active pic area can be set... means individual black borders sizes can be deleted. |
Hi guys! :D
I've been away for a few days (I've finally got a new job!) and come back to find this thread... My head is spinning :confused: . But it's good with new ideas even if we don't always agree with one another, right :wink: ? |

And here Kwag started to say that I'm wrong and this method will result in noise in the borders. And THAT IS ABSOLUTLY WRONG ! Quote:
Was I suppposed to split the threads just because I did the "big mistake" to start from a bad point of view ? :evil: Quote:

Because I wanted to say that while you were testing, I wasn't doing scuba diving ! I did tests on my own of course ;-) Quote:

@Dialhot
Would you be so kind to post your *.bat file? Please...? I want to try it but it was awhile since I used MEncoder with command lines, and I don't remember how... :oops: . |

To many ping pong postings today. :lol: Quote:
At the beginning of this thread there where also nice discussions on another subject, remember?? :P :D Quote:
A "x y" determination would be essential!! As if not we ONLY could crop centered in the Yaxis and some DVDs/Captures got a NON centered active Movie area 8O You agree? |

BTW I can use this file with the latest CVS builds posted by incredible, right? EDIT: This is a 2 pass *bat, or am I wrong? |

Phil ... you did put the noise BEFORE scaling = Risky -- a scaling of the noise??!
