Overscan 1 or 2 on xvid conversion?
doing xvid conversion to kdvd 720*576 and i wanted to know whether to have overscan=1 or overscan=2
|
Nothing to do with xvid or not.
TO achieve best quality, use 704*576 (and not 720*576) with overscan 2. |
thanks dialhot, il do that,
|
dialhot, i want to convert a ntsc video to kdvd, and keep the ntsc signal
the template i got is 720*480, to achiev the best quality possible on this conversion should i change the resolution to anything else? |
Can't you realize yourself that your question doesn't have any answer the way you post it ?
What can I tell if I don't even know the length of the movie ? Stop asking "what's better, what's better ?". Do some tests by your own and let your eyes decide ! |
the length of the movie is 3 hours, your right il go off and do some tests,
just asking cos on the post above you said to use 704*576 ( instead of 720*576), i thought there may be a better resolution setting for ntsc, but il try |

(but bo not resize ! Cut off 8 piwel on each side. If you resize you will screw up the A/R) |
what do u mean by do not resize?
this is what iv been doing in my script i put in GripCrop(704, 480, overscan=2, source_anamorphic = false ) and then after i have loaded up my template in tmpg i have changed the output video size from 720* 480 to 704*480 ( this is because none of the templates have a res. of 704*480 is that okay? sorry for the hassle |

Crop(8,0,704,480) Quote:

okay heres my script with the addition u suggested:
AviSource("C:\chan.avi",false) BlindPP(cpu=4) Blockbuster(method="noise",detail_min=1,detail_max =3,variance=0.1,seed=1) Convolution3D(1, 6, 12, 6, 8, 2.8, 0) Crop(8,0,704,480) GripCrop(704, 480, overscan=2, source_anamorphic = false) GripSize(resizer="LanczosResize") Undot() TemporalSoften(2,7,7,3,2) DCTFilter(1,1,1,1,1,1,0.5,0) GripBorders() TextSub("C:\chan.srt") after this i open up tmpg, load up my template, load up my script, then i change the output video to 704*480, is that cool? what exactly am i resizing here , the source video or the template in tmpg? how do i avoid resizing? iv had 'GripCrop(XXX, XXX.... in all my scripts |

2. The source Video for shure! 8O And if you wanna be more exact, by this you do still resize within the 704x576 incl. 16-16-16-16px on each side added so that this will again fit the 704x576, means the effect. Movie area will be downsized from 704x480 to 672x448 and with the above 16pix on each side you'll end up again in 704x480, .... thats the way of Overscan in Grip Crop as it does a resized! overscan. 3. :?: As you do apply to all your Movies an overscan area you cant' avoid a minimal resizing! as explained above in "2." |
okay, im a bit confused
so basically if im going to change the res. size in tmpg, i have to make sure iv evened it out in avisynth first, e.g if my output res. is going to be 704*576, in my script i should have: Crop(8,0,704,576) GripCrop(704, 576, overscan=2, source_anamorphic = false) that will allow me to change the the video size in tmpg but if my output is going to be 720*576 (a resolution available in kdvd template) this is not resizing so i just need GripCrop(720, 576, overscan=2, source_anamorphic = false), overall by saying 'do not resize' you mean dont change the out put resolution in tmpg, only use whats avalable in the templates, if i do change it i have to do the above sorry again for being the nusance |

Don't make that. Just open up tmpg, first load up your script, then load up your template, and last, in settings, put the output video res (704*480). |
Predator DID YOU READ WHAT DIALHOT wrote, he clearly says load up the template, then the script, then the video res. settings

Thas is why I said to you taht this method will assure you that this is THE SCRIPT that controls the things and not the template. But as always, if you just tested the things before to post, you should have seen them by yourself ;-) Quote:
I wanted to say DO NOT CHANGE THE SIZE OF THE SOURCE BY MAKING A DIRECT RESISIZING FROM 720 -> 704 ! The crop command CUT the picture, it didn't resize it. You see the difference ? If you do Crop(704,480) and then Gripcrop(704,480) and then Gripsize, you just CUT the image, and you don't screw up the A/R. If you do directly GripCrop(704,408) + Gripsize, you will resize the picture (because the source you provide to Gripcrop is 720x480) |
