vcd (film) -> dvd; why! didn't i pay attention

[dani82]

i red bit and pieces of articles and guides about vcds must have a 48mhz audio file to be dvd compliant, and how a 23.976fps can be patched or something to be dvd compliant; now i just found out it has to be an svcd/mpeg2 format for it to work (that really sucks*)

anybody know a way around this? if i patch the vcd the way it is, will it still work correctly in my dvd player?


* lucky for me, my dvd player supports *.mpg files, unfortunally i created them as multi-language vcds

Vcd resolution 352x240 is dvd compliant. a mpeg1 video can be imported directly into a dvd authoring program. The Audio is not compliant, as it must be changed to 48,000. Frame rate for ntsc must be 29.97. Mpeg2 video does not mean it has to be svcd. Svcd is mpeg2 but at a specific sixe 480x480. To be dvd compliant in ntsc land size must be 720x480, 704x480 or 352x240. No other size will work. All of the audio must be 48,000 and ac3 or pcm.

:confused: did you even read my thread? most of what you said, i stated; i just need to know if there's anyway to make a 23.976fps vcd, dvd compliant (dvd-vcd)

pulldown.exe should add the necessary flags (23.976->29.97), I assume it's fine for MPEG1.

And BTW, 23.976->29.97 pulldown is a very basic piece of dvd knowledge, did you even read the guides? ;)

[dani82]

i probably did (bits and pieces :D ), pulldown is actually the same question i'd ask of patching, will it work correctly in my dvd player?

Well, I just did a search and it turns out pulldown is not possible with 352 x 240/288 MPEG-1 streams, and that's why 23.976 is a supported VCD framerate (as opposed to 23.976+pulldown=29.97). Unless the doom9 posters are incorrect, of course.

I imagine then that the patcher solution (if does actually one exist) involves fooling the authoring app into thinking the stream is 29.97 and hence dvd compliant.

Generally when standards are breached the discs will play correctly in some players but not others (SVCD on DVD is a prime example).
