"Do you have a TV that can add the borders itself YES OR NOT ?
In other words, does your TV handle anamorphic pictures or not ?
In other simpler words : can you force your TV in 16:9 mode or not ?"
YES and NO
one of my tvs can do that, the others don't!
THEN it's not a question of taste but a question of doubt !

see in my FIRST POST on this thread:
http://www.kvcd.net/forum/viewtopic.php?t=11053&start=0
if you had posted that questions/answers for me there:
"Do you have a TV that can add the borders itself YES OR NOT ? ...
If not, for sure you MUST add these borders during encoding..."
......then i will got the solution from you in your first post on this thread!!!.
now is a question of my personal taste cos i see the movies in all tvs!
Phil,you was very clear ! ...and i(am clear now)?

thank you very very much my friend!

thank you too ink!

what is anamorphic & anamorphic widescreen

magnific links posted by gerti67 in doom9:

http://www.dvdweb.co.uk/information/anamorphic.htm

http://gregl.net/videophile/anamorphic.htm

Neither 528*576, nor 528-544/480 are showed in http://www.uwasa.fi/~f76998/video/co...nversion_table
What are the PARs for those resolutions?

But if movies in DVDs haven't black borders, what is the real heigh of movies.
For example, when I load "The Matrix" anamorphic PAL in VDMmpeg2 (i se it like egg-head in cropping window) I need to crop 78 pixels from top and bottom for get the "film pixel".
How can I know before loading a vob in any software tool, what is a DVD "film pixel" size.
I want to know this value to encode it at full screen. Do I need it? or there is another way?

And another 2 questions: 1 - Why when we select overscan in Moviestacker or Mencalc, it is setted all around the frame and not only on both sides?
2 - Why, agree with talked in this thread, crop is not always to 704*576? but to values don't showed in linked table.

@Incredible: Maybe you missed my last 2 post. Do you have an answer for that?

As you see in PAL 544x576 gots an active px area of 526.5 ... the same relation to ...

720x576 where 702 is the active px area.

So as 702 wont match MOD4 its encoded at 704.

... as 526.5 wont match MOD4 so here also its encoded to mod4 means 528.

So 544*(512/351) = 793px shown & overlapping on a PAL 768 screen
... 528*(512/351) = 770px shown & overlapping on a PAL 768 screen

... 526.5*(512/351) = NON MOD8 but matched 768 !!!

Means BOTH (528 and 544) got a PAR of 512/351

Recalculation using the mhz and µs values:

544x576 will be played back using 10.125mhz at 53.7284µs
Full PAL is 768x576, means 14.75mhz at 52.000µs

(53.7284/52.000) = 1.0332

So ... 768*1.0332 is 793.49 which is 544 desqueezed to PAR 1:1 PAL.
So 544/1.0332 = 526,51 !!!! The active Pict. Area of a 544 Stream.

PAR: 793.49/544= 1.4586
Also: 768/526,51= 1.4586

BOTH 544 and 526.5(52 do have 1.4586 as PAR value


Lets do the same in NTSC


544x576 will be played back using 10.125mhz at 53.7284µs
Full NTSC is 648x486, means 12.306mhz at 52.65556µs

(53.7284/52.65556) = 1,02037
648 * 1,02037 = 661,2028
661,2028 / 544 = 1,21544 = PAR of 544 at NTSC

648/ 1,21544 = 533.14 is the active picture Area of 544 at NTSC (also PAR 1,21544 )

You cant as you never will match the exact filmpixels as most times the real active moviesize wont match 100% the 2.35:1 or 1.85:1 or 1.778:1

4:3 Tv (1.333:1):

768/1.333 = 576 = no resizing the height to get a Fullscreen one


16:9 Tv (1.778:1):

768/1.778 = 432 = resize height from 576 to 432



--------- below just for explanation but NOT real available as sources! -----

Widescreen (1.85:1)
768/1.85 = 432 = resize height from 576 to 416


Cinemascope (2.35:1)
768/2.35 = 326 = resize height from 576 to 326

Because! Theres no encoding AR Flag in mpeg1/2 at 1.85 or 2.35, so they do let it anamorph (1.77 and add the needed black borders to match 576

Because a) it would end up in an AR error and also b) cause the TV gots not only an overscan at the sides

??? I dont catch what you mean

Me neither.
But don't worry, I clarified all my doubts reading this trhead, the uwasa link and the pdf guide that you point me in another thread.
Thank you very much for your invaluable answers.

De nada

i thank you too ink. it's very cool and deserve a sticky

this was great and don't deserve to fade in a long thread.

Hi

So far so good.
All mpeg2 for DVD is encoded in 4:3, and then during encode added a playback flag, either 4:3 or 16:9, right?

That made me think:

A movie encoded with 16:9 flag will be "resized + added borders" by the DVD player to a 4:3 TV set to get right AR, right?
And if I buy a 16:9 TV set in the future the DVD player will send the movie to the TV with the right AR again?

So what's the point of encoding in letterboxed 4:3?
And how would that encode look in a 16:9 TV set? Would I have to redo all my backups again to match a 16:9 TV?

Just some thoughts.

Almost! The encoder "just" encodes the pictureinformation in the given Framesize, for instance 720x576. The encoder doesnt see if the input is squeezed (anamorph) or not he just recognises pixels in a mathematical order. So the "pure" encoding itself is not 4:3 neither 16:9, its just 720x576 or in NTSC 720x480.
right!
shure!
a) You gain from more compression in case of more Data stored on one DVD-R as the active Movietreatment is "smaller".
b) As VCD specs (and 352x288 DVD specs) don't allow anamorph encodings, you dont have a choice other than encoding letterboxing.
It will be positioned like a simple 4:3 TV Broadcasting, means a 4:3 Rectangled screen within the 16:9 proportion, where Borders will be added at the sides to compensate the 16:9 to 4:3 difference.
BUT: You can do enlarge that 4:3 letterboxed stream within the 16:9 in a proportional way so you wont have any borders at the sides and a perfect proportinal correct full 16:9 view.... but then the main goal of a 16:9 encoding ON a 16:9 TV Set is blown away as you would enlarge by this the height, means a blurrier view on your 16:9 TVset

Thanks Inc.

Very nice explanation

I'm only doing KDVD so I think I will be doing a lot of my future backups with the 16:9 flag...just in case I'll suddenly get a 16:9 TV set

-Anerboda

The biggest gain you will recognise is when playing back your anamorph 16:9 KDVDs on a (maybe) future xVGA (1024x768!) Beamer Device via a progressiveScan SAP Device as that Beamer does "enlarge" the final view extremely and any kind of artifacts/blurriness will let your eyes suffer.

When using TMPGEnc to encode (KDVD template and Kwag's optimal script with gripfit) a 16:9 NTSC as anamorphic, how do I set the flag?

Am asking as I intend to purchase a widescreen HDTV in a few months and would like the output to work with my present standard tv now and the future one later. I understand how anamorphic works, but not how to set the flag itself in TMPGEnc. My present encodes are all 4:3 non-anamorphic. As I don't have the widescreen TV yet, I cannot determine by testing, other than seeing if the encode plays properly with the standard TV. I do understand that one can "zoom" the 4:3 to fit the widescreen, but would rather make anamorphic in the beginning.

I would appreciate an answer from someone who is currently doing this with TMPGEnc successfully. I've asked this before, but never received a simple answer for setting flag in TMPGEnc.

Thanks as usual,

Just encode as 16:9. The basic rule is to use the same flag the source has.

I'm not sure if Boulder last post will be fully understood by Nicksteel so I prefer to re-word it :

- if you want to encode in 4:3 in tmpgenc, you put "4:3"
- if you want to encode in anamorphic mode, in other words if you want to have the anamorphic flag to be set in the mpeg, you put "16:9".

The state of the flag in the mpeg stream generated is the only diff between this two options in tmpgenc.

I should have used quote, I answered the question that was on the first line of nick's post and exactly what Phil says as well. If you don't use 16:9 for anamorphic encodes, you'll be watching eggheads on your TV unless you switch to 16:9 manually.

In TMPGEnc I should choose Video/Aspect Ratio/16:9?

In TMPGEnc I should choose Advanced/Video source setting/Source aspect ratio/ 4:3 or 16:9?

Sorry about all the questions, but I want to be certain. I will use:

GripCrop(704, 480, dest_anamorphic=true)
GripSize(resizer="BicubicResize")

in avs script.
