Hello!
I've captured my SVHS-tapes,and want to convert them to KDVD.
Using the KDVD-720x576-Full-D1_Pal_ template with TMPGEnc.
I've been using this Script:

LoadPlugin("C:\Programfiler\AviSynth 2.5\plugins\MPEG2Dec3.dll")
LoadPlugin("C:\Programfiler\AviSynth 2.5\plugins\Grip.dll")
LoadPlugin("C:\Programfiler\AviSynth 2.5\plugins\STMedianFilter.dll")
LoadPlugin("C:\Programfiler\AviSynth 2.5\plugins\asharp.dll")
LoadPlugin("C:\Programfiler\AviSynth 2.5\plugins\unfilter.dll")
LoadPlugin("C:\Programfiler\AviSynth 2.5\plugins\undot.dll")
LoadPlugin("C:\programfiler\AviSynth 2.5\plugins\kerneldeint.dll")
#
####
## Main section and static filters ###
#
AviSource("G:\Captured Video\Video 1.avi",true)
ConvertToYV12
KernelBob(order=0,sharp=true,threshold=7)
AssumeFrameBased()
Undot()
asharp(1, 4)
GripCrop(720, 576, overscan=1, source_anamorphic=false, dest_anamorphic=false)
GripSize(resizer="BicubicResize")
STMedianFilter(3, 3, 1, 1 )
MergeChroma(blur(1.5))
MergeLuma(blur(0.1))
SeparateFields()
SelectEvery(4,0,3)
Weave()

(I Know this is a DVD-source script,but I choosed to use it beacause the
Captured video was of pretty good quality.)

1. When I open the files in Gspot I get res. 720x540(1.33:1=4:3),
am I right this is NOT anamorphic film??

2. When I use the mentioned template,the default AR setting is 16:9 Display,
Is it a good idea to change it to 4:3 Display to get the right AR??or am I wrong?

3. When I open DV files in Gspot I get res.720x576(1.25:1=5:4),
how to get the correct AR from this one using TMPEGnc??
4. and I also read somewhere in this pages that DV can be Anamorpic,
any easy way to find out???

Thanks a lot!!!

Do a search for "Guide to dealing with interlaced sources" by Boulder. I think it is in the Optimal Scripts topic.

There is no native anamorphic mode for DV like there is in mpeg2. But some DV cameras will encode an anamorphic image into a regular DV 720x480 frame (such as the Canon XL2). You could also use an anamorphic adapter lens. However, most DV cameras that record 16:9 use letterbox video.

I read that guide and modified my script,
the script above are for DV,Interlace,Bottom Field first,
SVHS got top field first,my mistake

The Interlace part is correct ,I think,im more
worried about the AR and anamorphic settings

I want to avoid "coneheads" in my movies if possible!!!

The script you posted is for a 4:3 display. If your source material is anamorphic you need to change "source_anamorphic=false" to "source_anamorphic=true" and "dest_anamorphic=false" to "dest_anamorphic=true" in the GripCrop statement. This will cause the output mpeg2 to have an anamorphic flag.

Yeah I see,
but one more question,
as far as I can see non of my cameras,SVHS and DV,have any 16:9
"equipment",so I think the movie is non-anamorphic.(I saw a post from Dialhot somewhere,where he said that 99% of .avi files wasn't anamorphic )
I've looked in the DV-cam user-guide,the 16:9 lens was extra-equipment.
but back to the question,if I change from "Full Screen" to "Full Screen Keep Aspect Ratio 2" in TMPGEnc I got sideborders when encoding,will those borders show on a 4:3 TV???or only on a 16:9 TV??
(maybe a stupid question but I take the chance )

it's not a better choice changing in the encoder!
do like Peter1234 recomendations changing the script, not in tmpgenc.
and that borders, you can see in the pc but not on tv.
do that:
encode a few minutes from your S-vhs source, burn in RW and play in your standalone/tv!
remove your doubts with this little test!

the viking,
If you are encoding anamorphic with TMPGEnc you will also need to set the Aspect Ratio on the Video tab to 16:9 in order to get anamorphic output.

yeah, right again Peter.
after read that last details i understood!

i did my recomendations to do tests cos i never encode from s-vhs
(i only encode dvds) and don't knew what could happen,then,
trusting in your hints, i post my confirmations to the viking.
and a little sample in standalone is a good hint to remove doubts!

the viking,
If your input video is not anamorphic just encode everything using 4:3 aspect ratio.

Hi jorel,
Thanks for checking.

okey,I'll try that,using following line: GripCrop(720, 576, overscan=1, source_anamorphic=false, dest_anamorphic=false) and change from 16:9 Display to 4:3 in TMPGEnc settings.
Thanks!
