I heard from the company that sold me my Pc. They told me that for my school film projects, I should encode them to mpeg-4 because it is awesome in every way. File size, sound + video quality. The guy told me that Internet Explorer Version 5.0 has this built in, but I can't find it. He also said that it is compatibly playable on Dvd players.
Anyone have anything to say to this? Anybody tried it?

Well, this is second or third generation testimonial, but I do have a friend who was seeking my advice on the subject of encoding his film to mpeg then distrbuting it via CD to be played on DVD players. Now the result we concluded was that some DVD players can read non-DVD encoded CDs and extract the mpeg information and play it. But many DVD players seek only the DVD codec and won't play mpeg if it's not found. It's a sort of copy protection to prevent you from going to blockbuster, capturing an entire film to your HD, writing it to a CD and having a perfect laserdisc copy that won't deteriorate ever. Apparently most PC dvd drives can read non DVD discs for obvious reasons, though I hear the creative labs DVD player doesn't read mpeg from a cd without the DVD codec. Though honestly I've never tried it.------------------

Creative DVD does read a Video CD, which is encoded in MPEG-1, and not DVD (MPEG-2) codec.Never heard of a stand-alone DVD player playing MPEG-4, but I know that many are backwards compatable with Video CD's, so it seems plausible. The main problem is the fact that most DVD players just can't read a CD-R disc. There are a handful of models that can read CD-R's, but even these vary on which brands of blank discs can be read, etc. |

Yes, but oddly enough they will read a CD rewriteable. go figure. probably the same reason some cd drives wont read em. |

Hard to say isn't it? For stand alone, they say you have to buy a 15,000 dollar machine to have the re-writable playback. A lot of it is pretty weird, and unpredictable. One guy here told me that my dvd player will play my vcds, as long as it is able to play cdrs. I tried a cdr and it worked! I tried another time, with a different audio cdr, and it spat it out!? I can't understand it any more. Oh yeah, how big are mpeg-2 (dvd)files compared to mpeg-1 (vcd)? And how severe is the quality loss from crossing my avi over to mpeg-2? I don't think there would be any, because they do dvd with it.

Mpeg 4 is a new MPEG standard (Motion Picture Experts Group) but is very different from the other MPEGS. While MPEG 1,2,3 (MPEG2 is DVD) were designed to have maximum picture quailty on compression of large files (like 7.4gigs)MPEG 4 however is designed for web video for low-definition low-bandwith transfers. Check the codecs in Premeire and render your movie, it will look like real video. QuickTime 4's web video is based on MPEG-4, it's a step above real in quality but still far short of mjpeg, cinepak, or mpeg2 ------------------
