Do I need to format iDVD projects for viewing in Australia?

I've just completed a photographic slideshow with music in iMovie and created a DVD of the same in iDVD. The project was a gift for a friend who lives in Canada, but has asked if she could have another copy that she could send to family in Australia.
a) Do I have to convert from NTSC to PAL for the Aussies to watch it?
b) If it needs to be converted to PAL, does the iMovie have to be convereted first, or can the complete conversion happen in iDVD?

The general recommendation when making a DVD in iDVD for US, European, and Australian use, is to make an NTSC format disc.
To quote FShippey:
We have been told here many times that most recent PAL DVD players will also play NTSC DVDs (of course, the opposite is NOT true).
It is possible to convert/have someone convert your NTSC source to PAL. But simple is usually better and cheaper - go with NTSC format DVDs

Formatted iDVD project complete with Themes, etc...burning through Toast?

I need to use Toast to burn my completed iDVD project. Worked a looong time making it perfect with formatting using Themes, custom Text pages, etc... I'd hate to lose all that, but need to use Toast to compress the video to fit a Single Layer DVD. Does Toast preserve the iDVD formatting or not? Can iDVD finalize a project with Toast burning in mind? Help?

If I'm not mistaken, you can create a disc image to the desktop from the file menu in iDvd. Then burn said image in Toast while selecting the fit to dvd option.
But you may be restricted to selecting one of Toast's basic themes.

Exporting iMovie/iDVD project for PC friend to edit

I recently posted a question about how to take an iMovie/iDVD project and export the files so that a PC user could take the project and edit on his PC using a video editor. It was suggested that I share the iMovie project to QuickTime and then burn on to a CD. This sounded good at first but then I did some research and saw that sharing to QuickTime means that the quality will be lost (saving to CD setting) and will only be something like 320 x 240. Plus, it takes forever. Even longer if I set it to full quality but by that point, the file wouldn't fit on a CD anyway.
I did see that I could save the movie back to a mini DV tape and then give that to the PC person so that they could just bring it into their computer via their camcorder. But what if that person doesn't have a digital camcorder?
For the project in question, I've been asked to take some VHS tapes and convert them to digital. I've done so using a digital converter. They want a DVD of what was on the tapes, which I've done, but they also want the files so that they can later edit to their tastes on their own time on their PC and then later create a DVD. Given the above, what would be the best way to do this? Isn't there something in the movie project files that I can dump to disk?

a) consider the usage of an ext. harddrive...
b) in iM's "share" dialog, you find the option "selected clips only"; so, select a few clips you like to export, check that box, done... you can "split" your clips at any point to create segments of approbiate size by hitting apple-t at any position in timeline..
c) share/Quicktime/expert options/click "share"/ offers you a dropdown menu, where you can choose the "avi" container...
(your User Interface is for sure english!)
you can click options, and choose the dv codec (which is your project's native video codec)... no loss of quality, and probably compatible for your friend..
d) a dataDVD-r fits ~20min of dv video... 4 disks?
e) using Disk Utility, make sure, you use a PC-compatible disk format....
f) Plan B) export your project back to tape, give your friend the miniDV...

Need help with calculator project for an assignment...

Hi all, I please need help with my calculator project that I have to do for an assignment.
Here is the project's specifications that I need to do"
"""Create a console calculator applicaion that:
* Takes one command line argument: your name and surname. When the
program starts, display the date and time with a welcome message for the
user.
* Display all the available options to the user. Your calculator must include
the arithmetic operations as well as at least five scientific operations of the
Math class.
-Your program must also have the ability to round a number and
truncate it.
-When you multiply by 2, you should not use the '*' operator to perform the
operation.
-Your program must also be able to reverse the sign of a number.
* Include sufficient error checking in your program to ensure that the user
only enters valid input. Make use of the String; Character, and other
wrapper classes to help you.
* Your program must be able to do conversions between decimal, octal and
hex numbers.
* Make use of a menu. You should give the user the option to end the
program when entering a certain option.
* When the program exits, display a message for the user, stating the
current time, and calculate and display how long the user used your
program.
* Make use of helper classes where possible.
* Use the SDK to run your program."""
When the program starts, it asks the user for his/her name and surname. I got the program to ask the user again and again for his/her name and surname
when he/she doesn't insert anything or just press 'enter', but if the user enters a number for the name and surname part, the program continues.
Now my question is this: How can I restrict the user to only enter 'letters' (and spaces of course) but allow NO numbers for his/her surname??
Here is the programs code that I've written so far:

Keeping Temporary Files Around? Need properly formatted .ali file for a CHM help.

As part of our localization process, I need to access the .ali file that is in the temporary folder. Back in RH 7, I could just copy the .ali file from the RH project, but in RH 9 it's now in an XML format and isn't in a format directly usable with CHM files. However, when RH compiles the CHM file, the .ali is changed into a format I need. Unfortunately, if I decompile the CHM file, the .ali file isn't there. So my only route is to grab it from the temporary build folder. If I'm compiling a large file, it's not a big deal because I have time to make a copy of the .h file in the temporary folder and paste it somewhere outside of the folder but for smaller projects the temporary folder is around for just a little while before it is removed.
Does anyone know of a way to keep the temporary build folder around after compilation of a CHM file finishes so I can access this file?
Thanks,
Jared

Use the Disk Utility in the /Applications/Utilities/ folder to create a disk image and use the disk image to store the Mac files; they will keep their date and other Mac specific information. The disk image's contents cannot normally be used on a PC.
There are other ways of doing this if the disk image method doesn't work for some reason; these include using this method of creating partitions, and installing MacDrive on the PCs.

I need help with exporting project for the web

Probably something i am doing wron g but here are the problems. When I use Quicktime Converter, if I try to convert to a Quicktime movie or an MPEG-4 nothing happens and i get a 'File error;File Unknown message' when i try to convert to an AVI File, it works, but even though I have already rendered the project, it shows up with little flashes of blue that say 'unrendered'. and finally, when I try to make it a w

Need to format the partition for Boot Camping to NTFS. How do I do this?

So yes, I have searched online to find a way to format the partitioned to NTFS so I can Boot Camp my Mac Mini and have found nothing that I can use. Instead, all I have found are horror stories of others messing up their Macs when doing this. I want to be sure I do this as correctly as possible because I do adore my computer.
For Boot Camping, I have followed the steps and started the installation of Windows 7 but when it comes to choosing the partition it says I can't because it's not in NTFS format. Any help on this would be greatly appreciated.

Heh! Yes, it's one of those things that are simple, once you know where to look. Glad you got it figured out.
You won't quite be done once Win 7 is done installing. You'll notice that the graphics in Windows likely won't be very good, and in general running kind of slow. That's because the Windows DVD had no drivers for Mac hardware.
So you need your Snow Leopard disk. Either the first gray disk your Mac came with, it if shipped with Snow Leopard, or the retail disk you purchased.
From the Windows 7 desktop, put the Snow Leopard disk in the drive. Windows will pop up the usual message about what you want to do with an external drive. Choose "Run Setup". It will run for a while as the drivers for your Mac hardware are installed for Win 7.
Once that's done, you'll have menu icon for Apple Software Update. Run that to see if it needs to download and install any other Boot Camp updates, which would any updated Win 7 drivers for you Mac.

Finished iDVD project for web?

My IT guy (on a PC) wants to put an iDVD presentation I made on the intranet, keeping the intro, menus, etc. intact. Does anyone have any ideas how or what program we would use to go about this, if it can be done at all?

vespagurl,
After thinking about your problem for a while, the following is what I would do:
You COULD playback your DVD in your computer and use SnapzPro X ( http://www.ambrosiasw.com/utilities/snapzprox/ ) to capture all the playback sequences as a movie. The movie would not be interactive - but perhaps by making several movies of the different playback options on the DVD, you could create a web page that would allow the Internet viewer to choose the path they want to view.
Hope this gives you some ideas.

Bbc I player ,global !for viewing in Australia

Am trying to find the app for BBC I player, global version, which is supposed to be available in the apple store, but when I search for it there are no results. I understand from various articles that it should be available for Australia now. Anyone ant ideas?

I'm using my computer's iTunes, where you can click on the flag at the bottom right of the store's homepage to then view other country's stores - though I can't buy anything from them as I haven't got an address anywhere else and you need to be physically in a country in order to buy/download from it.

What format to use for iDvd.

Hello and thank you for reading.
I am currently saving home videos onto my hard drive as .dv files via iMovie events. I am also using iMovie to cut these files however I see fitting.
I am trying to find a format to convert these files so that it will provide clarity once they are burned onto a dvd (via iDvd) and will not be an overwhelming size (each hour of .dv footage is about 12 gb). Thanks for the help.

As Klaus says, .dv is excellent for bringing into iDVD for creating DVDs. In terms of storage for any future editing, highlights, compilations, etc. you can:
* send your video back out to tape (full resolution storage, but flattens titles and transitions into the video; need a tape reader in the future)
* retrieve the desired video from the DVDs or disc image (mpeg-2 format is fine for viewing, but it's tossing lots of content; eg, at 12 gigs per hour in .dv format, it's about 4 gigs when compressed into mpeg-2 format. The format conversion tools keep getting better, but that's a big gap to overcome).
* use large hard drives to store .dv format files (storage keeps getting cheaper and I like the flexibility of this option since the video is relatively uncompressed).
Personally, I keep the original files and a virtual DVD (disc image) so I can easily make another DVD for someone (from the disc image) or I can jump back into the details of that project.

Mass Producing a iDVD project - Print shop for Mac

I have been doing a couple of iDVD projects for friends and family. One of my projects got into the hands of a school principal who would now like me to do a video yearbook for her school. I don't have the capabilities for mass production, but I am aware of companies that do this work. Can a copy of an iDVD project be used as a master for a large scale (500+ copies) production?
Also, one of the companies I am looking at has to have graphics from specific software:
"We can accept these software programs on Macintosh or PC:
•FreeHand
•QuarkXPress
•Illustrator
•PageMaker
•CorelDRAW
•InDesign"
I have been using Print Shop for Mac because it incorperates iDVD templates in it's projects. Any of the choices above as similar match to Print Shop?
Thanks in advance.
iBook G4 Mac OS X (10.4.5)

If you plan to have these DVD's "mass produced" use DLT > Glass Master. Also i'd recommend using apple's top end / professional apps and not consumer / iLife apps in order to avoid possible returns and possible playback issues with many consumer medias.
Pressed DVD's from a glass master have far fewer issues with playback (and also last longer) than a "burned" DVD-R medias.
Hope this ifo is Helpful and good luck.

Is there a way to exort an iDVD project back to iMovie?

Hi.
I need some help please!
I made a training video a couple of years ago for a friend's company. She now would like to have additional copies burned. The problem is I saved the dvd project on my hard drive, but I deleted the imovie project.
Of course, this time she needs to change her company logo in the intro (which would require me to remove the first 5 seconds of the original movie)... and I'm unable to edit it. Can I extract the movie some how? or if save it as an "archive" would I then be able to move it to iMovie?
I would really appreciate feedback!

The answer depends on what you have available.
The best method is to locate the movie footage used in the original iMovie and reimport that into another iMovie project and create a new iDVD project with it. There will be no loss of quality.
Just so you know, saving your iDVD project is nearly useless without saving the movie that is in it. An iDVD project is not self-contained. Think of it as a file that holds aliases. When you create an iDVD project, the iMovie used is referenced, not physically moved into the iDVD project. Same for any photos or audio files used. It is unlike an iMovie project (at least version 6) where the movies, photos and audios ARE moved into the iMovie project. When iDVD burns a project, it collects the referenced files for the burn, but does not keep them permanently in its project. So, if you have saved any iDVD projects, and you did NOT save the media used, all you have is the 'shell' of the iDVD project. If you open it, iDVD will not be able to locate the missing media and will alert you that it cannot find the proper files.
If this is the case, and you no longer have the original movie footage, or you don't want to have to re-edit it, you will need to get one of the burned DVD disks, and extract the movie from it.
Any type of extraction of compressed data will result in some loss of quality because the data must be decompressed and then recompressed again for another DVD.
If you don't have one of the DVDs you previously burned for this project, you will not be able to create another iDVD project from the first one, and without the original movie footage, you are out of luck.
If you do have one of the old DVDs, you can use a variety of software to extract out the video: Handbrake, Ripit, or Streamclip. I have not looked into Handbrake, but many use it and think it works well. Ripit will extract the video into format for iMovie....seems easy enough as reviewed in MacWorld recently. Others use Streamclip.
If you think that you will need to create more DVDs of this project, or if you would like to save your complete iDVD projects in the future so you can burn more DVDs, you should do a 'Save as Disk Image' from within the iDVD project for each one. This process looks exactly like the burning process, with the same encoding and taking the same length of time to complete, but the end result is a disk image file, not a burned DVD disk.
The advantages of having a disk image file are several:
First, it is self-contained, with all the media data encoded in it. So now, you CAN safely delete both the original iDVD project and its original iMovie without losing the ability to burn disks in the future.
Another advantage is that it can be a backup for all your burned DVD disks. What if a disk is damaged/breaks/melts/ etc.? With a disk image file, you just burn another one.
Disk image files save drive space because they are smaller than the combination iDVD project /iMovie projects used to create them.
You never need to worry about renaming, moving, deleting or changing any of the media used in any of your projects causing iDVD to lose connection with them. All the media encoding is in the disk image file.
And, another advantage is that you can burn DVDs from the disk image file, using Disk Utility or Toast, getting more consistent burns, since you are not depending on iDVD to pull in the media.
Here are some helps for creating a disk image in iDVD:

If you have some previously burned DVD disks and you think you would like to have had disk images for them, you can create a disk image file from a burned DVD disk.

IMovie/iDVD projects

I've made a handful of iMovie/iDVD projects for family members. Right now they are taking up space on my hard drive. While I doubt I will go back to them, I would like the ability to work with them again. Can I take one of the DVDs that I created and just reload the iMovie/iDVD and add thing/make edits at a later date?

.. another option is, to use a back-up software as Toast 7/8, which allows socalled 'spanning'...
choose Data, drag iM project into Toast.. it will ask you to insert DVDs.. and more DVDs.. as tilman stated, an iM project contains 13GB per hour project length plus the many hours you have imported...
you need Toast to re-import such a disk collection, to re-assemble the many files of an iM project...
.. it is mostly recommended to spend 100$ for some external, firewire connected harddrive (format to hfs BEFORE use...) ... then, it's simply drag'n drop ...

How do I burn a iDVD project on more than one computer?

I created an iDVD (7.1.2) project with three elements. Two iMovies made from iMovie '11 and a presentation made from Keynote (5.1.1).
I deleted the chapters in the slide show to help simplify matters and it did cut down on my burning/processing time.
I made this iDVD project for my son's 5th grade graduation. We would like to burn 135 copies to give each family one 'favor/dvd' for memory keepsake.
I do not want to burn 135 copies on my Superdrive (new to owning a mac) and do not want to ruin my Superdrive for a school project.
I can not take this to a commericial duplicater because of copyright issues with the music. We are not selling the copies, just giving a memory keepsake to the kids- of the year and the slide show from graduation, the other iMovie in iDVD, just contains one page of specifications; like my contact info and songs used etc..
I have parents that are willing to help me copy the movie, however I don't know how to do this?
I don't believe any of these parents have iDVD.
Someone mentioned through all my readings on apple communities and google, making an "ISO" of your project then anyone can make a copy of your movie on any platform: PC or Mac. What is an ISO? How do I make a ISO?
If I have a .img file from saving a disc image - would I burn the .img file to a dvd and give it to someone else to copy? Are there other files that need to go with my .img file?
If/When someone takes my .img file and puts it on their computer how do they copy it? Do they need burning software?
Can I just give a friend a burned DVD of my movie to burn copies on their computer?
What I tried: Bought a LaCie burner to use a external drive vs. my (Superdrive - worried about overuse). Saved project as a "Disc Image." Mounted to my Finder and then burned to external drive with disc utility. This worked successfully 4 times in a row then kept getting message "unsuccessful burn" I took the drive back to Fry's. Not sure if it was the drive?
Any advice to a newcomer would be great!
Summer has already begun and I would like to finish this project as soon as I can.
Thanks so much, Deanna

Yes, you can distribute a burned disk of the project to those who can create duplicate disks. Or create a disk image of the iDVD project using the File ➙ Save as Disk Image menu option.
Then you can distribute the disk image to those who will burn the disks. For PCs you'll have to convert the .dmg file to a .iso file so they can burn it. This website describer how: Mac Help - Convert and Burn Mac .dmg or .img to .iso Windows PC-Compatible Disk Image
Suggest to them to burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
It would be prudent to rest your optical drive for about 30 minutes after burning 3 disks in a row. That will give the laser time to cool down before you start another batch.
