3 Resizing Methods, which one is better?
I want to encode two AVIs:
(1) 624x352 856kps 23.976fps (2) 640x352 1029kpbs 23.976fps Their quality, as you can see, pretty low. Does it matter if I use DirectShowSource over AVISource? I have read so many posts that I am confused whether I should use BicubicResize or LanzcosResize, and I'm having a headache deciding on the "appropriate" resizing script. Which one should I use, which is better than the other, or does it depend on the size of the AVI? (1) 624x352 Method 1 Method 2 Method 3(2) 640x352 Method 1 Method 2 Method 3 |

Resize and add borders at the end. AFAIK LanczosResize is better at resizing to higher dimensions, bicubic is better going down to smaller dimensions.
If you're trying to convert these to DVD, you should resize them to 720x something, add black bars, and use the Aspect Ratio feature of the DVD to get the proportions right. |

Use 0.3a as it resize before adding the borders. You can also change the default value to "ntsc" as it seems you're in a ntsc region. And as you can see I prefer spline resize....less less less halos than lanczos. |

Since you're making an NTSC DVD, all 6 methods/scripts are wrong - completely and utterly wrong.
I already told you in the other forum how to resize: http://forum.videohelp.com/threads/3...=1#post1960045 And since you're playing with the big boys now, you go back to the original DVD you already own and use that one for reencoding, and not some intermediate AVI. What's that you say? You downloaded this AVI? Then we can't help you. Go back and read the rules you agreed to abide by when signing up here (rule 6), and the announcement: http://forum.doom9.org/forum-rules.htm http://forum.doom9.org/announcement.php?f=6 I'm locking this thread unless and until you can PM me with evidence that this AVI wasn't obtained illegally. I don't expect to have to reopen it. Be thankful you're not getting a strike. |
