Mini DVD's

[bilc]

I noticed the other day that several movies ( example : Harry Potter ) have been recorded on the 3" mini dvd disc and can be played back on a regular dvd player. In the sleeve was one disc with the entire movie on it. My question is can dvdd and shrink backup an entire movie onto this mini disc and if so how is it done. I watched the movie and the quality was very good, I saw no difference from a regular dvd disc. Anyone wish to comment on this.

3 inch mini DVDs have a capacity of about 1.4 GB.

Just change the disc size in Shrink to this capacity. Because of the limited space you would want to reauthor it movie only with only one audio/subtitle track.

I watched the movie and the quality was very good, I saw no difference from a regular dvd disc.

On what hardware (brand and model number) did you view this mini-DVD?

I understand that the video was on mini-DVD media - but do you know what format the video was? Was it DVD format (.IFOs, .BUPs, .VOBs), or was it possibly .AVI/MPEG4, or similar?

[Video Dude]

Harry Potter was released on Mini DVD. (It can be found on Amazon.)

Mini DVDs are exactly the same as DVD, but just a smaller disc. They are fully compatible and within the DVD spec and can be played on all dvd players.

I am suprised to hear that the Mini DVD and the Regular DVD have the same picture quality for a full length movie. Usually Mini DVDs have only about a half hour to an hour of video. I usually find Mini DVDs in cereal boxes and they contain short episodes of cartoons.

The only way you couldn't playback a Mini DVD on a settop player is if it's tray lacks the additional grooves to hold the mini DVD, though I've seen some listed on videohelp.com that specifically do or do not support Mini DVD playback.

I am suprised to hear that the Mini DVD and the Regular DVD have the same picture quality for a full length movie.

And that's why I've asked a couple of questions of "bilc"...

[CWR03]

I agree, it's quite doubtful that it's the same quality as a standard DVD since the Potter movies are about 2 1/2 hours long each. If viewed on a small TV or a portable DVD player the difference probably wouldn't be noticeable, but there must be some loss of quality.

[bilc]

The 3 " DVD was played back on a portable DVD player so picture quality on a 7" screen was good. I then viewed it on a 17 " tv set, also good quality. I have not as yet tried it on my 46 " HD......I'm guessing it will look horrable. As for the format of the DVD , I read it as an mpeg.

@bilc

Thanks for answering my questions ;>}

As I'm sure you know, virtually anything will look good on a 7" screen. If, as you said, it's an MPEG, my guess is that it's in MPEG-1 "1/2 DVD" format...

Was this a commercial, pressed disc or a burned disc?

i opened the link above and on the mini dvd cover theres a dvd video logo.

doesnt dvd video need to be 720x576?

352x240 NTSC or 352x288PAL is for vcd, if the mini dvd is vcd it should have the vcd logo instead.

i remember backing up my harry potter dvd and it didnt look that welll when compressing it below 4 giga.(only main Movie)

I smell a "con", "trick" with that kind of logo on it

SAMSUNG Debuts New Mini DVD Player For Kids

Mini-DVD is the newest way to enjoy movies and TV shows anytime, anywhere. Mini-DVDs are just like standard 5" DVDs, but they're only 3" in diameter. They play in specially-designed Mini-DVD players, which are so small they easily fit in your hand. They also play in full-size DVD players, so you can use them at home, too.

@ricardo.santos

Not important but, I just wanted to note that the originator of this thread, 'bilc", is not the one who provided that link - nor has "bilc" yet indicated whether the disc he/she viewed was a commercial, pressed disc or a burned disc.

Chances are he/she DID see the same type of disc referred to in the link, but until "bilc" responds, we won't know with certainty.

By the way, a quick bit of research at the organization that provides licensing of the DVD Video logo, DVD Format/Logo Licensing Corp.

http://www.dvdfllc.co.jp/dvdlogo.htm

does not seem to indicate any particular resolution requirements, only physical attributes of the media and file structure...

(It IS possible, with programs such as "TMPGEnc DVD Author", to author DVDs at "half" resolution)

[bilc]

To clarify a question posed, the 3" DVD was a commerical disc. Some research on this ... Warner Bros and now Paramount are releasing upwards of 50 films, but they are family or children rated. If the mini disc pans out regular movies will be pressed onto the mini.

@bilc

If you still have access to this mini-disc, I'd be curious to know what the video resolution is - and the audio format...

[Video Dude]

The official Warner site has the Mini-DVD specs:
(This would inlcude the Harry Potter movie.)

Mini-DVD uses Dolby 5.1 Surround, Dolby 2.0 Stereo, or Dolby Mono.

Mini-DVD movies are 4:3 aspect ratio.

Mini-DVD uses full DVD resolution (MPEG-2 720x480 for NTSC).

Mini-DVD can be dual layer with a capactity of 2.47 GB.
- Single layer holds 34 minutes (1.36 GB)
- Dual layer holds 65 minutes (2.47 GB)

Full feature films are usually split over 2 Mini-DVD discs. Source: (Click on FAQs)

Like I said in my above post, Mini DVDs are exactly the same as DVD, but just a smaller disc.


EDIT: So to get back on topic with bilc's original post, it would be difficult to backup a regular movie to Mini-DVD with acceptable quality because the only blank Mini-DVDs available are single layer 1.36 GB. You would have to split the movie over 2 or 3 Mini-DVD discs.

[CWR03]

Interesting, thanks for the research.

I can see that not only would it be difficult to back up a typical movie to a mini-DVD, but when and if they come out with a dual layer one they will probably cost more than the original DVD. Even now the cheapest full-size DL disk I can find is $10, where most movie DVD's are under $15.

[setarip_old]

Per "bilc": I noticed the other day that several movies ( example : Harry Potter ) have been recorded on the 3" mini dvd disc and can be played back on a regular dvd player. In the sleeve was one disc with the entire movie on it.

Based on the Warner specs as posted by "Video Dude", this (An ENTIRE "Harry Potter" movie on ONE commercial mini disc) continues to appear to be an impossibility...

[CWR03]

I suppose it could be done, though I still feel doubtful about a 2 1/2 hour movie like Harry Potter fitting on one disk in any sort of quality. If the file could be brought down to half resolution while maintaining DVD Shrink's ability to compress it, it would probably look fine on a standard TV. Even Xvid has trouble getting a movie that long below 2 GB without reducing the resolution.

[setarip_old]

@CWR03

I suppose it could be done

No, it's now been clearly indicated, as per the parameters from the Warner site listed by "Video Dude" that a COMMERCIAL minidisc (even D/L) will hold a maximum of 65 minutes of video.

Your speculation regarding using "half resolution" is a reiteration of what I already speculated about very early on in this thread - BEFORE the Warner specs were posted by "Video Dude" - and are not applicable to what "bilc" has already confirmed is a COMMERCIAL disc ("minidisc"/"miniDVD")...

[CWR03]

Sorry, I meant burning a custom mini-DVD containing a full-length movie (which was the original question), and even of that I'm doubtful.

[cypher_soundz]

dvd @ ½ res would still be compliant for dvd spec (not for Warner specs is seems though)

maybe it was a daul layer flipper disk , that would bring it up to a single layer normal dvd size.

@bilc can you give us some more info plz ?

[bilc]

read your post, don't know what you mean about more information. I believe I posted all info in past posts that were requested by other members. Could you be more specific.
bilc

[Video Dude]

I think everyone was wondering if your Harry Potter mini dvd was only on 1 disc or was it spread over 2 or 3 mini dvds? If it was on 1 disc, was it a flip disc having the first part on side A and the second half on side B?

[cypher_soundz]

Yes Video Dude is correct , thats the information i was talking about :)
