Which script for 352x240 VCDs?
I would like to know which is the best avi script(version1-4) to use at this low resolution and is there any changes i need to do to it for this resolution.
Any other hints would be great also Thanx |
Use this, i encoded Matrix reloaded as MPG2 with it and it was almost perfect. It's the V4 without undot.
Code:
AviSource("C:/m.avi", false) |
Thanx muhali3,thats a long movie is there anything to change for a shorter movie :)
|
You could change BicubicResize to Lanczos for smaller movies. I don't know what else you should do, i got a cq of 62.34 for matrix reloaded with that, so you should be able to get a CQ around 75

Use the exact same script as ever but use CQ_VBR insteed of CQ.
(except for high action movie as it seems that CQ_VBR has some problems with them). Do not change blockbuster parameters like suggested by muahli. It's way too much ! The more the variance, the more noise you add, and the more the denoising filters that follow will let in the picture ! The only thing I change according to the length of my source is the MAX bitrate : I use 64-2300 everytime and reduce it down to 1800 if the movie is very long (and even to 1300 for making extra long KVCD near 2h40min). |
Thanx Guys
@ Dialhot Do you still use 2300 max if the resolution is 352x240,also how do i go about using cq vbr,(prediction and stuff)Do i just use cqmatic and pick the cqvbr option instead and thats it. Thanx again |
use 1800 as max bitrate. Yes, use CQMatic.
and when you're using CQ_VBR don't be surprised if the value is only 25 or something, that's how it's supposed to be :o |
I have a bunch of div3's which are vcd quality, i.e. low res and low bitrate. According to GSpot, the bitrate comes out at around 400-600 kbps, depending on the source. With that being said, what kind of changes should I make to the min/max bitrate in tmpgenc? I have 13 of these files which I wanted to put onto a DVDR... I sometimes find prediction with this number of files a bit cumbersome, so I usually just set CQ to 90 to ensure I'm not losing any quality from these low quality source files. Any comments on this? What if I were doing CQ_VBR, what should I set that at?
EDIT: oops, I lied. When I load these files in Moviestacker, it reports an the average video stream bitrate is ~1800kbps (min1200, max2600).... so with that being said, should I just leave min/max at 300/2500? Also Dialhot, do you agree that we should be using V4 script without undot? |

You can use Bicubic wihtout Undot as some report they like it (that I not agree when the source is a divx -> too soft) but V4 is V4. That means Lanczos + Undot. |
yeah, when i convert dvd-rips to 352x240 KVCD, lanczos+undot takes away alot of the mosquito noise .
