Begging for New feature

PLEASE...can you make the resize infinite?...I have a few rips I would LOVE to make bigger than 800/whatever....I can NEVER resize bigger than width 800...please please please make the resize bigger.

[Duplex]

Just a Question.....
WHY do you want to resize the movie with such a high resolution?? :confused:
Every DVD has a Resolution of 720x480, right?

So I would think that there just can't be any Quality improvements
by selecting a higher resolution... You would only strech the picture.

If I ain't right, please tell me but for me there is no reason to resize a movie too a higher resolution than the Original has....

greets, Duplex ;)

I am trying to encode (have encoded..will encode again)Independence Day. Properly set at 16:9 res800/340, Gknot tells me a 3disk rip using the stat file I created, bits/pixel*frame=86%(so does first pass size).(A GOOD thing). Well..I want a full 3 disk rip but it chaps my ass to use more br than what I need. So I thought ...hmmm... if I could only resize it past 800/340(or whatever )so it would be approx 70%, I woud have my full 3cd rip and not be wasting br. It is not often I have a movie that compresses that well but there have been a few that do. '6th Sense' 'Unbreakable' and 'Dinosaur' immediatly come to mind. The ability to correctly resize past the max limit set in Gknot could have given me 3cd rips on all of these. For me...the thing is not about making it smaller, the thing is about absolute quality without wasting anything. I eventually solved my dilemma for Independence Day by using Nandub, setting anti-shit to 18 and min quality to 25 full process. I got my 3cd rip.
It still bothers me that I could not go bigger and actually utilize the extra br involved in doing it.
I'm sure this sounds like so much drivel to the folks that do this all the time. Let's face it...the whole reason the Divx format exists is to get dvd quality in a "MUCH" smaller package. So I guess it's strange that someone actually wants to go bigger..(but it would STILL be under the size of all those damned vob files!) I suspect I am using up valuable forum space intended for those with REAL problems..So I'll stop now. ...

Hi :),

I dont think this is a waste of time posting btw. I think you may notice that you'll have higher quality by aiming for a first pass size* of higher than 70% even if it means dropping the resolution - try to get 100% - my reasoning is ur res is already nice and high ... it makes sense to increase res if u have over 75% and a low res, but thats not ur case - experiment and see for urself.


* thats the Video size/First pass size that comes up after you load ur stats file...

Every DVD has a Resolution of 720x480, right?

...just 2 nitpick, wrong ( eg PAL ), but it in the same ballpark ;)

[Darrell]

So you are saying that if my first pass size says 86%...slide it to 100%?..What the hell, I'll try it. Would I still want to follow the Gknot edicts of the perfect rip by making an ecf file and doing the stats correction, loading both into Nandub for a second 1rst pass?

[diji1]

Well, it may be hard to notice the difference in between 86% and 100% compared to 70% ( it will be better quality tho imo at high res ), but i personally prefer to sacrifice some res when i can afford to in favour of getting that first pass size up. im saying i think ull have better quality by getting the first pass size up as close to 100% as possible and then increasing res after that if you can ( or want to ).

I've never done a "second first pass" ( could you point out some info, or is there something in the forums ? - or is that just 2nd pass ;) ) but i assume it would all be fine.

[Darrell]

This is taken directly from the Help tab in GKNOT :D

Phase 6 (OPTIONAL): another first pass (3-pass-encoding).
you do this if your first pass is below 60%, above 100% or if you want the PERFECT encode:

!!!
at this point forget about the rules of thumb for bits/pixel*frame. e.g. it doesn't matter if you go below 0.20 now, maybe you
just have a movie that compresses really well...

1> move the resolution slider or maybe change your filesize- and audio-settings so that you get 70% in
'bits/pixel*frame-first-pass-percentage'(also at the bottom), and save a new .avs.
IMPORTANT: if you got a first pass percentage below 50% you have to override gknot's suggestion for resizing and
CHOOSE BILINEAR this time! if you were above 100% take sharp bicubic...
2> Open YourMovie.avs in Nandub
3> Select Fast Recompress from the Video Window Menu

4> go to video -> sbc-options -> sbc-settings -> ECF and load YourMovie.ecf

5> Press F8 or "First Pass" from the File Menu
6> Enter your preferred file name into the requestor (YourMovie.stats, you can overwrite the last one) and press OK to save.
7> When encoding is finished jump to phase 3, check 'show graph', then SKIP PHASE 4,5 and 6 and go directly to phase 7.

Essentially,(as I understand it anyway) it means the perfect rip can be accomplished by sliding the res bar to 70%, save as a new *.avs...
Then...with your original stats file still loaded in Gknot, create an ecf file. Load it in Nandub (instead of a stats file) and do another first pass. Then the resulting NEW stats file(which I appropriatly name '2nd pass.stat') is loaded into Gknot for the usual correcting and misc. voodoo that is performed in the stats file editor.

At least that is how I do it..I hope it's a correct interpretation of the instructions.

[diji1]

yeah, sorry, i've actually read that but haven't done it - thanks for the info regardless!

diji: That "2nd first pass" thing is mostly obsolete from before the time people thought of compressability checks.

darrell: if I get this right, you want to resize to a size larger than the original, so you can get a more reasonable first pass %? This has got to be the dumbest thing I've heard in a long time. :rolleyes:

[obelix]

@matei:
In the "second first pass" Nandub can use the ecf-file from GKnot, so the stats file will be more accurate because the location of the keyframes is already known. So the "second first pass" is not completely useless.
You can test that easily. I don't know how much impact this has on the final quality, though.

Come on...I've asked WAY dumber questions than that before! :)
Anyway, I use a resolution 1152/864 on my monitor..so 800/340 just is not that big.
