PAL DVD -> NTSC DVD, CCE SP Crash

[damsan05]

Hi,

I am trying to convert PAL DVD to NTSC DVD with DVD2SVCD. Dvd has subs and AC3 audio.

I keep getting the crash on CCE SP when I edit AVI Synth file.
I add the following lines in Avi Synth:

BicubicResize(720,480,0.0,0.6)
AddBorders(0,72,0,72)
Convertfps(29.97)

Everything works fine if I try to encode PAL DVD and not edit the Avi Synth file but when I edit the file CCE SP keeps crashing.

I am using DDV2SVCD Version 1.2.1 Build 2. Has anyone seen this error?

Thanks.

Try playing the file "Avisynth_script_file.avs" in Media Player.
Do you get pictures or red text?

I get red letters with the following error:

"ConvertFPS: requires YUY2 input"

How do I resolve this? Thanks.

When I play AVS file with Assumefps(23.976) I can get it to play but when I encode with CCE SP I am getting the following error:

"Frame size 720*624 is not supported. Supported frame size is up to 720*576"

So I can not use assumefps or convert fps. PLS help. thanks.

Post the full contents of your avs script please. A quick re-order should have it working in no time. :)

Cheers

Hi Nick,

This is the original AviSynth file:

LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\Mpeg2dec\MPEG2D~1.DLL")
mpeg2source("C:\PROGRA~1\DVD2SVCD\Movie\DVD2AV~1.D2V")
BicubicResize(720,432,0.0,0.6)
AddBorders(0,72,0,72)

I edit that file in the following way:

LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\Mpeg2dec\MPEG2D~1.DLL")
mpeg2source("C:\PROGRA~1\DVD2SVCD\Movie\DVD2AV~1.D2V")
BicubicResize(720,480,0.0,0.6)
AddBorders(0,72,0,72)
ConvertToYUY2()
Covertfps(29.97)

I still keep getting the following error:

"Frame size 720*624 is not supported. Supported frame size is up to 720*576"

By converting to YUY2 I I resolved the problem which I had with Convertfps but I can not figure out how to resolve the problem with frame size unless I use another frame size.
Thanks.

Original:
-------------------------------
BicubicResize(720,432,0.0,0.6)
AddBorders(0,72,0,72)
------------------------------
This is the normal resizer/addborders for PAL anamorphic to 4:3 conversion. Total number of lines is 432+72+72=576 which is the standard.

Modified:
------------------------------
BicubicResize(720,480,0.0,0.6)
AddBorders(0,72,0,72)
------------------------------
This script gives you a total of 480+72+72=624, which is not the NTSC standard.

You have two choices:
a) Keep the AR (probably anamorphic) as it is. In this case, no Addborders statement should be included
-------------------------------
BicubicResize(720,480,0.0,0.6)
-------------------------------

b) Convert from anamorphic to 4:3. (Be sure the original is anamorphic)
------------------------------
BicubicResize(720,360,0.0,0.6)
AddBorders(0,60,0,60)
------------------------------

As you can see, in both cases the total number of lines is 480 (NTSC standard)

Jsoto, thanks for your help, your suggestion resolved my problem. I have no idea how I did not remember to look at that "addborders".

I have some questions regarding PAL->NTSC conversions.

1. which method is better from the two bellow? I have seen both of these mentioned in DVD2SVCD Q&A.

bicubicresize(720,480)
convertfps(29.97)

or

bicubicresize(720,480)
convertfps(29.97*2)
assumeframebased()
separatefields()
selectevery(4,0,3)
weave()

I used once the second method for VCD but it gave me combing effect on fast motion scenes. I have not used it for DVD.

2. I would like to create my NTSC DVD with AC3 audio. Can I demux the PAL DVD and in Scenarist for example just replace MPEG audio with AC3 audio and multiplex the VOB files? Would my audio be out of synch in that case since video is encoded NTSC and audio is PAL?

3. My subtitles got out of the screen on my NTSC DVD. To avoid this should I just use for PAL standard title position the value from NTSC standard title position (400) in subtitle tab of DVD2SVCD?

4. how does picture look more normal after conversion (not streched) when I have anamorphic PAL DVD -> when I convert it to anamorphic NTSC (without adding borders) or when I convert it to 4:3 NTSC (with adding borders)?

I will try to do some tests with one portion of the video to check these but your opinions would be appreciated. thanks.

Hi,

The only problem I am left with are subtitles now. my subs get out of the screen no matter if I do a 4:3 conversion or leave the screen anamorphic.
I tried to move the subs by adjusting Y position for PAL and NTSC but DVD2SVCD automatically puts it back to -1 or to value 2 in which case they are high up, on the top of the screen.

How can I place the subs within lower black stripe on the screen when I convert PAL DVD to NTSC DVD? thanks.

I wanted to reply to your 2nd question about PAL audio and NTSC video. Yes, they will be out of sync unless you convert. BeSweet can convert your audio from 25 fps.
Also, you can demux the original stream and replace the audio file in a new mux. Are you sure that your PAL audio is MPEG audio? This is allowed for PAL discs, but it's a little unusual. I've only seen this on some older discs. All the current PAL DVDs that I've seen don't use MPEG audio at all. That's just FYI. I'm sorry I can't help with your other questions.

[damsan05]

well, thanks everyone for their help, I resolved my problem and NTSC DVD looks pretty good.
I used Convertfps(29.97) and I used the original PAL DD 5.1 audio. Video and audio or not out of synch.
I also resolved the subtitles problem, I used the value 380 for positioning the subs.
Very nice. Encoded with CCE, 3 pass VBR everything seems to be in sync, video, audio and subs and plays just fine.
Thanks!
