View Full Version : I'm all confused about NTSC Divx -> PAL SVCD

Since D2S accepts an AVI (Divx) file as a source, I'm trying to use it to convert my Divx to SVCD so that I can watch them in my standalone DVD player.
The problem is I have lots of Divx movies with 23-24fps, which is the NTSC standard, right?

I used to extract video and audio to separate AVI and WAV files and then convert with TMPG. But I like CCE quality much more than TMPG and CCE is much faster too. On top of this DVD2SVCD saves me a lot of work.

But in this case (NTSC source) do I need to take any extra steps or is it just a matter of activating that NTSC to PAL option in D2S? What about the audio? Do I need to have both audio and video together as NTSC source or can I process audio later (in Besweet or something else)?

Btw the only solution I found to put permanent subtitles in the SVCD was using virtualdub to frameserve (with subtitler filter), because the subtitles are in a separate ssa file (converted from srt). I wanted to use just an avisynth script but I don't know how to use ssa subtitles like that. Any idea? I don't have the original ifo nor the vob files, mind you.

If I don't do the framerate conversion from NTSC to PAL do I have to use the NTSC resolution for SVCD? It won't look right in my 16:9 PAL TV for sure...

Thanks a lot in advance for any help.

Well, last night I left DVD2SVCD encoding one huge Divx file (only video, no audio) to SVCD, but when I woke up I noticed it crashed at 75% encoding ("Could not write mpv file" or something like that was the error message. There was plenty of hard drive space, so I don't know what happened)... Damn! Almost 8 hours of work for nothing!!!

I will try another option: direct encoding in CCE through Avisynth script, with resizing, framerate conversion and textsub subtitles filter - I just don't know yet how to make subtitles bigger...
Then I'll use Besweet to convert audio to 25fps.
I hope this works...

Dont ask me why but I have noticed that if you edit the avisynthscript as part of video encoding and resize it to pal or ntsc size then CCE does not crash.
When the script come up to edit.
Remove the add borders line and chenge the resize to

480,480 Ntsc leave the 0.00,0.70 in so Bicubicresize(480,480,0.00,0.70)
480,576 Pal leave the 0.00,0.70 is Bicubic Resize(480,576,0.00,0.70)

If I leave the borders in it crashes.Dont know why ?
There is no coneheading on a 4:3 or 16:9 TV so it works for me and I always use Bicubic resize with CBR as the 4XVBR multipass also cause a freeze or crashes.
Try it and see if it works for you.

Also make sure the DIVX file is on your hardrive when you load it up and not on a cd.

If this is bollocks just ignore:stupid:

Thanks for your reply madmuppet, but I always use VBR.

Anyway, the method I'm using now works fine (direct video encoding in CCE 2.5 through Avisynth script, then Besweet audio conversion, then BBMpeg to mux, then VCDImager). I encoded just a little bit of Lord of the Rings to see if it worked and yes, the quality is great!

It just takes too long to encode :(
As I write this, CCE is at about 3% of a 12-hour encoding work! But then I am using 4-pass VBR with sharpen filter and textsub filter and resize et all, so I accept that it takes that long... I decided to use the sharpen filter just to see exactly what everybody is talking about, and because the source in this case is a Divx file, not DVD, but I guess that is what is slowing things a lot!
If I don't notice the difference, then I won't use it again.

Cheers.
