25 fps -> 29.976 fps film

[the * dude]

I am new to this game (+ six months), but does any no know how to convert a 25fps (Pal) source to a 23.976 fps (ntsc-film). I am obsessed with fitting my vcd's on one CD, this will help alot to fit those pesci 148min vids which are in 1.85:1 ratio......

But I dont want to re-encode a mpeg (tooo much loss in quality)!!!!
(Avi -> Mpg or better, *.d2v ->mpg)


Thanks!

converting to 24fps film will not save you any disc space. as all you do when you comnvert is slow the 25fps to 24fps, meaning your film is 4% longer, making your 148 minute movie 153 minutes instead.
if you want it all on one disc, go buy a dvd-rw drive.

Which brings to mind a related question I have: With TMPGEnc I tried converting an 800MB PAL SVCD (25 fps) to NTSC SVCD (30 fps). I was surprised when the size was something near 1200MB. If the additional frames don't affect the size, just the length, what accounts for this?

I also tried converting the PAL SVCD to NTSC VCD (24fps), and it was surprisingly large there too, around 600MB.

I must be overlooking something.

yes, when you convert 25fps to 30fps, you create five redundant frames every second, wasting space. converting 24fps to 25fps, you literally speed up the film, making it 4% faster.
if you have to convert a PAL film to an NTSC film, the best way it so slow 25fps to 24fps and run pulldown.exe (don't ask, i don't know.)

although why anyone needs to convert from PAL to NTSC is beyond me, your DVD player supports PAL, so should your TV, and if it doesn't, your dvd player can convert it on the fly. PAL is higher resolution with better colours anyway......

When I went from 25fps to 30fps, it was still the same length, at least according to WinDVD, but I've seen that counter become confused before. If I'd played it and timed it I suspect it would have been several minutes shorter.

The reason I did this is this quote from my JVC XV-S300BK manual:

"This unit accommodates the NTSC television system and can playback discs recorded with the NTSC system. Note that the unit cannot playback the disc recorded with the PAL system."

I'm not in a position right now to prove it wrong, but if you think this is false, I can give it a try at a future date. I have seen other threads here about certain models handling it and certain others not.

well to the best of my knowledge, it has to be able to playback PAL, or it's not within spec.
i know for sure that -all- players here in the UK are multistandard. it's quite possible the people writing the manual have put "you cannot play back PAL discs" meaning "you cannot play region 2 discs" but the format and the region code are not the same thing......

Such, unfortunately, is not the case here in the U.S. Here, it's luck of the draw as to whether PAL will work as-is or not -- and you can't even assume that the higher-end models will work and the cheap ones won't.

Example: My DVD player is a $59 Apex AD-1200, and the TV set is a 27" Toshiba. A friend of mine has an $800 Philips DVD+R(W) set-top recorder and a brand-new, huge 50"+ widescreen TV from Sony. My setup will play back a PAL disc just fine, as verified by a copy of "The Plague Dogs" (which is, apparently, not region-coded) -- though I haven't done any tests yet to see if the Apex is actually converting it to NTSC, or if the Toshiba is actually able to digest a PAL signal. His Philips DVD+R(W) unit, on the other hand, will attempt to play this disc, but his ultra-spiffy widescreen Sony will choke on the PAL signal.

Hence, the need for a good PAL -> NTSC conversion method.
