Encoding with higher resolution than source

[RathO]

I just want to say that i tried something i never tried yet in my way of backing up my dvd collection. I encoded using AutoGK (always the latest ver) a widescreen dvd. But not with my usual resolution. I streched it to 1024X(whatever) AutoGK choosed 1024X576 (1.78). Also, i go for the 2Gb (max for DVDRs) option. If you guys want to see the log for its numb3rs ;)... here it is:

====================================

Before doing this, i made a test with the trailer, and the results are very impressive. So i gave it a shot for the movie. It is longer to encode, but i think its worth it.

I know its kinda against the "ethique" to encode in a higher resolution than the source, but.. i had to try.. and oh no... the quality is so great that i'll have to re-do my whole collection :)

Next step is to closely look to the result of this "streched movie" on my hdtv :p

I don't want this thread to be like i say this is the best or you should do like this or whatever. I just want to share my little test here.

PS.. hum.. not too sure how the attachement will come out, let's try it. Mod, feel free to delete.

[Shinigami-Sama]

ewll iirc
encoding at high than source uses more bits but is better for veiwing on hd stuff
I;ve been thinkning of doing it to my 16:9 movies
I have 1080i hdtv it was prety cheap and I wanna test it out
so from your reaction seems like a good idea to run some tests

Weeee, another 1024X576 encoder... :D

Have you read the Reloaded HQ (http://forum.doom9.org/showthread.php?s=&postid=486155#post486155) thread ???


Bye

[SeeMoreDigital]

Great...

Yet another forum member has discovered the merits of generating 1024x576 square pixelled encodes. But personally I would only do this from an 720x576 anamorphic source, not an 720x480 source :D

And, seeing as though you live in Canada, you now have the opportunity to play your encodes in hardware, via one of I-O DATA's (http://forum.doom9.org/showthread.php?s=&threadid=84003) new high-def/res stand-alone players - if you felt so inclined...


Cheers

The thread "Anything to gain by using higher resolution than the DVD? (http://forum.doom9.org/showthread.php?s=&threadid=85220)" had some aspects, too.

Btw, thats only valid if you burn ya DVD's in ISO-mode... ;)

If you burn them in UDF-mode, you can go for 1/2 or even full DVD size !!!

hmmm
what about expanding a non-anamorphic source to fit 540 to look nice in my tv?

and about hte player
why not jsut watch from my comp to my tv eh? ;)

Well since i'm using AutoGK, i can't choose the vertical resolution... and im not sure i want to go back the hard way.

So now that i have my "new way" :D of backing up my dvds, i'll have to re-think my HTPC. I still have my old setup running: RCA cable, old graphic card *that can barely play the 1024x576..* and since the rca is the only output available on my video card, i will have to think about buying a new card eventually.

1-What king of link between the card and the pc would you suggest?
2-I heard about the HDTV ati video card, is it good?

Regards

I want to encode some anime dvds so they look nice on my they;re 4:3

and for hte conenction
s-vid cable
I have no other way till I find a dvi>hdmi adapter...
though when I find one
*-*

All "store bought" DVD's also contain either 4:3 or 16:9 DAR (Display Aspect Ratio) signalling, in order for the video image to be displayed at the correct shape on your display device (ie: TV, PC monitor, projector etc).

It has been my opinion for quite some time that increasing the vertical resolution of a DVD source does not really offer much visual improvement. But increasing the horizontal resolution of a DVD source (quite often) does!

though when I find one There's nothing much wrong with S-video (providing your video card is up to the task). But they do have their limitations!

So... if you are after an DVI to HDMI adaptor, does this mean you have a display device with an HDMI input?

my tv is 1080I with hdmi in yes...
and I want to incerse hte vertical so that the tv doesn;t have to streach the video on its own witch looks like crap
I's rather it disply in 540p or 1080i maybe
I alrady knew aoubt the DAR flag
I;ve been her ea while after all
and my card is up to it
overclocked gforceFX5200
and well
my comp is up to it also
it;s got les add-on cards than yours but has more power
p4 3ghz Ht
1.5ghz ram @ underclocked to 333mz cuase of one cheap card ¬_¬ that I'm goiong to replace soon
and a fsb@800mhz
so my comp will take what ever I thought at it
decodes snow quite well so hd xvid should be no problem..

A 4:3 image (even with or without black mattes above and below the image) should be able to be correctly displayed on a 4:3 or 16:9 screen!

The problem is most probably to do with your video card!

Is there a setting in your video cards software that allows you to select your screens DAR size (ie: 4:3 or 16:9).

If there is not such a software setting... this may explain why your TV can't display your sources correctly ;)

[Shinigami-Sama]

lol
i;ve tried through my dvd player too
I ment that hte vertical resoultion is streched to 540p and that upsize on hte tv sucks
it displays correctly
it jsut resizes like crap though a sive thats all

[SeeMoreDigital]

I'm sorry... I don't understand what you mean by "540p"

Can you please confirm whether your Mpeg2/DVD source contains 720x480 pixels and has a DAR of 4:3 and does not include black mattes above and below the image?

Plus, what shape is your screen, 4:3 or 16:9?


Cheers

[Shinigami-Sama]

the dvd is full d1 no black bars
the tv is 16:9 1080i
meaning that I want to upsize hte vertical resulotion of a 4:3 dvd to 540 so as that the tv doesn;t have to do a realy shitty nearest neighbour upscale thats all

[SeeMoreDigital]

I would have thought your 4:3 image would be "completely" filling your 16:9 display... like this: -

http://img221.exs.cx/img221/5752/ntscfig04b7qq.gif

So if anything, you would have to manually set your TV's aspect ratio settings to 4:3, forcing the left and right mattes to appear... like this: -

lol
like I said
I know that
but my tv upsizes to 540p
or 1080i if I want it to
which is why i want to manuly make ht e resultion 540p or 1080i if it;s already interlaced
I know I;d have to change my AR on hte tv
I end up changing it all hte time when I watch tv or differant anime
but I;v found my local cable provider doesn't tag things very well..
so I find keeping it set to 4<full> makes most things look correct
which i'm not alone most of the peopel with nice tv say hte same thing..
so basicly you;ve told me everything I already know mate :P

But I still don't know where your "540p" info has come from!!! 480i/p, 576i/p, 720i/p, and 1080i/p... I'm familiar with... but not 540p :eek:

Good luck in your search,


Cheers

[Shinigami-Sama]

lol
Iuno
thats what it says in hte manual that I loked at
it won't display 480i/p
it upsizes them to 540p or 1080i depends on whatI want it to do
it;s deinterlacer is pretty nice
not hte best but it;s nicer than mostso if hte great smd doesn;t know
I guess one my own @___@
