Best Resizing for 704x576

[loa-ash]

Hey guys
I've recorded a channel that has resolution 704x576... without black border...In my avs script I put a resize with Lanczos to 640x480...I'd like to create a rip for my dvd stand-alone...and watching it in TV... In my opinion the resize is correct for TV... and what you think about???

thanks all

Keep original resolution and Aspect Ratio (4:3)

Without resizing?

example avs script:

------------
LoadPlugin("C:\Programmi\AviSynth 2.5\plugins\mpeg2dec3.dll")
LoadPlugin("C:\Programmi\AviSynth 2.5\plugins\decomb521.dll")

Mpeg2Dec3_Mpeg2Source("H:\gg.d2v")

TomsMoComp(1,5,1)

#LanczosResize(640,480)

-------------------------------

good solution?

I am not AviSynth user, but I think that you can delete resizing line.

EDIT
Speed and quality will be better.

Are you sure that your source is interlaced?
try also remove deinterlace line (with TomsMoComp.)

If you're in a 625-line (PAL) country (e.g. UK, europe etc) then 704x576 is exactly what your TV wants, and can be burnt directly onto DVD without any change.

If you're in a 525-line (NTSC) country (e.g. USA) then it's unlikely you're receiving a 704x576 source directly. You an convert it to NTSC to burn to DVD and view on your TV. Just re-sizing isn't enough - there are plenty of threads on converting PAL>NTSC - see the AVIsynth forum for more.

thanks all!!

I live in Italy, so the DVB source is PAL format with 25fps and 704x576. This night I'll convert m2v->avi directly without resize or deinterlace.. then I'll post the results and an uncompressed source...I think that need a denoise filter such as removedirt or grain...

see ya soon :D

Hi loa-ash,

When you say you are converting m2v->avi, what video stream are you encoding/placing within the .AVI container?


Cheers

[loa-ash]

I'm using Xvid

[SeeMoreDigital]

Okay... if your encode is XviD, have you remembered to include PAR/DAR signalling the the Mpeg4 video stream?

And, if you have done that. Have you also remembered to install a suitable Mpeg4 direct-show decoder filter, that detects PAR/DAR signalling?


Cheers

[loa-ash]

Wait... I'll check...

Argh I don't know what that mean.... :S

[loa-ash]

ok, I've understood!! thanks a lot!

Sorry to sound newbie but why is your DVB source 704x576 and not 720x576?
I'm definately missing something here... afaik 720x576 is standard DVB size.
afaik is not always a fact, though =)

afaik is not always a fact, though =)It depends on the broadcaster and/or distributer!

720x576 is the most commom resolution for 4:3 and especially for 16:9 anamorphic content, followed by 704x576 for 4:3 content. But I've seen 528x576 and even 352x576 used in the UK for DVB-T and DVB-S.

Thank you SMD.

My pleasure... and welcome to the Doom9 forum...

this is a screenshot from dvb-s source uncompressed... in my opinion needs some removedirt or removegrain avisynth filters....

I'm fairly sure it is a DVB supported resolution.
Here in Australian the TEN network broadcasts 704x576 on its SD channel (16:9 anamoprhic). Why? I have no idea :confused:
