Convert MP4 to DVD

[KMWNAZ]

Relatively new to this. I have downloaded from YouTube some demonstration videos of toy products that my grand daughter watches in the car. I downloaded about 10 of them and the program I used converted them all to Mpeg 4 files. I tried using my Toast Titanium Ver 11 for MAC program but it complains that several are PAL format and the rest are NTSC. Now that they are in Mpeg 4 format I was wondering why that matters? How can I tell which is which? Is there a program that would ignore the difference and just rip them all to DVD? Appreciate the help

PAL has a frame rate of 25.0 fps; NTSC has a frame rate of ~29.97 fps (and NTSC adjusted "Film" has ~23.976 fps).

YouTube videos might have even non-standard frame rates, or double frame rates not compatible to the "DVD Video" standard, only to some HD formats.

Converting frame rates is not trivial. Imagine slicing an already sliced pie anew, with a different number of slices...

i suspect most car DVD players wont care if its nstc or PAL , they will play it all

you might separate them, put all of each type on different Discs

author a PAL dvd and a NSTC dvd
i bet the player will play both equally well

But authoring tools will usually deny mixing of both on one disc.

Does your player really support only DVD Video? Or possibly other formats as well? Which brand and model is it?

He did say granddaughter
So I'm going to guess, and say it's an add-on headrest backseat type DVD player, width possibly aux video game input
But no USB for digital multimedia
So he needs to author two discs
Or just pick ntsc and let avstodvd change the pal files to ntsc,
His granddaughter is not going to notice any flicker or jaggies I the you commercials

Thank you all for the replies.

The DVD player is an Advent (headrest style) in the SUV.

The issue isn't so much playing it, it's that the software (Toast 11) It wont take the playlist and cut the DVD because it's mixed PAL and NTSC. Not sure why as they are all MPEG 4? That's what you get when you download them as a playlist. I can't figure out how to seperate them as the details seem to be lost in the INFO when you click on them for frame rate.

"theewizrd" are you saying the avstodvd will burn a DVD and convert PAL files to NTSC? If so I'll try it. You're right she won't notice a little jiggle.

Yes it will convert
But I've never tried adding a playlist
All my work ha been done with individual files on Windows pcs not Apple and not using playlists
