Pal to ntsc again and space
#1
Posted 24 March 2007 - 09:19 AM
I guess my questions are, is there a better program to use to convert pal? How much room do I need? Three times the size of the file or more? How do I force toast to use the temp file it created? Should I have chose not to use the same name for .toast file. just deleted that one? Used a different name?

As for the unexpected quit during the PAL conversion that could be due to a lack of hard drive space, to a defect in RAM or to a defect in the source MPEG file. Usually the latter just results in Toast hanging.
I don't know any way to force Toast to use a partially completed file in the Converted Items folder. It typically will use fully completed files, so if you had three titles and it crashed on the third one that the first two would get reused.
Another application I'm aware of that does PAL/NTSC transcoding is MPEG2 Works. I have no experience with it.

I will look for MPEG2, is that for the mac? Where can I get it? I was aware there was an mpeg2 component available but not a program by that name.

I, too, have used the Fix Timecode Breaks feature in Streamclip. Glad it's there.
The application is called "MPEG2 Works 4". Search for it at versiontracker.com.

Once toast finishes converting and encoding, I will have a .toast image, hopefully. What can I do at that point to rearrange the menu that is messed up, so that the main menu is first to load and that all segments play sequentially? Will it take a long time to encode again?

The settings Toast has for menus are check boxes next to "auto play disc on insert" and "play all items continuously." Apparently you had the first box checked and the second box unchecked.
You'll need to have Toast re-author the DVD. If you saved the project as a .disc file and did not empty the Converted Items folder, then you simply could change those check boxes and choose Save as Disc Image. But if you don't have that from the previous attempt then you need to drag in the MPEGs and set up your menu title info again.
You can extract the MPEGs from a .toast disc image by mounting the image file and using the DVD button in the Media Browser to access the mounted disc image. Of course you are working with limited hard drive space, so you'll need to trash that disc image after the extraction to free up space.

Right now, in Converted Items folder, there is a tmp file, that is 4.9 gigs and growing. My finder still says I have 10.9 gigs available. So I have no idea what is going on. There is also a SPU.temp fle which is small, and a DVD.tmp folder which is empty.
I wish toast had better help files which detailed the process instead of pretending it was so simple and making it transparent to the user.

Toast does not use the menu from the source DVD unless you are copying the source DVD, not just its titles. When you choose DVD video as the format in the Video window Toast creates its own menu. The menu has the information and title order of what appears in the Video window.
When you disc image is finished you can mount it to preview how it plays in DVD player. Be sure to empty the converted items folder before burning the disc image to DVD (using the Image File setting in the Copy window). You'll need that spare hard drive space.

Speaking of space, it would seem that I will need in the future to consider it will require almost 4x times the size of the mpeg file. Because right now that temp file is 5.37 gigs and the source was 4.3 gigs, and the temp is only 2/3 done, and then it has to write the .toast file, and that I imagine will be at least 4.3 gigs, and hopefully not the I imagine 7 or 8 gigs size of the temp file.
Is this normal? I mean toast gave no warning I would need that much space. I have been deleting furiously. I can not even use toast to burn backups while this is going on.
It would be such a help if there were a document that I could read that explained exactly how toast performs its functions. Then I would not have to pester you so much. I feel like such a fool. I can program in six languages, but I am helpless to use a program with so little documentation. I am also a newbie to the world of video formats. I can understand the con concept of wrappers from C++ and Java, but no clue as to details of what is happening with these video files.

The Toast menu is formatted in the Video window before you Save as Disc Image. You can see the result by mounting the disc image and playing it in DVD Player. Normally if you don't like what you see (and haven't quit Toast and haven't emptied the Converted Items folder) you would just trash the disc image, change the layout or text in the Video window and create a new disc image. However, since you are having Toast transcode the video I'm not certain if Toast would go through all the re-encoding again. So the alternative way would be to empty the Video window and empty the converted items folder and then use the Media Browser to extract the MPEGs from the mounted disc image file. That way there wouldn't be any need to re-encode those MPEGs again.
Your source was only a little more than 4 GB but Toast is creating much larger files when it is re-encoding. This suggests that your original video was very compressed and the re-encoded video is not compressed as much. Typically Toast fits about 2-1/2 hours of video to a single-layer disc so yours must be longer than that. When you have a disc image that meets your approval when played in DVD player, you will need to use Toast's fit-to-DVD feature in the Copy to make it fit a single-layer disc. This requires more free hard drive space again. Had you kept the content on the disc under 2-1/2 hours my guess is you wouldn't need to go through the additional fit-to-DVD compression.
As for documentation regarding Toast, there is the getting started guide, Toast Help (which is pretty much the same as the getting started guide) and the knowledgebase articles on the Toast support page. What you're trying to do is rather complex, though, so I'm not surprised that its giving you headaches.

Hopefully compression will not take so long. So now when toast image is done, I should trash converted items? Trash the mpeg file? Mount the image? Arrange menu items? Burn another toast image? And finally to disc? Or no? I would have to burn to disc to get the compression? Or is there some way to force a toast image to be a certain size?

When we're done here you'll will have been through enough to be qualified to answer everyone else's posts.
In order to transcode the video Toast has to decompress and recompress the MPEG as part of the process. All you see is the re-compressed MPEG in the Converted Items folder and in the VOBs that are in the disc image. Toast has a custom encoder window where the settings are made for how small the MPEG file will be. Unfortunately you'd have to know how to calculate average video bit rates plus the audio bit rate to know how many minutes of video will fit a single layer disc at any pariticular custom setting. That's why the Fit-to-DVD is such a great feature. You can have the encoder bit rate set too high for a single-layer disc and Toast will "requantize" the disc image content to fit. The problem in your case is you limited available hard drive space. All this requires additional space to complete.
As I've noted, the disc image you have created may be fine as far as menus go but just too big. You'll find this out when you mount the disc image and preview its contents with DVD Player. If you like what you see then you can empty the converted items folder and trash the MPEGs that you copied from MPEG Streamclip. Now choose the disc image with the Image File setting in the copy window and click the burn button. Toast will ask if this is for a single-layer or dual-layer disc. Choose single-layer and Toast begins the requantization, also known as additional compression or fit-to-DVD.
If you don't like how the menus look but the video is fine, then you can still empty the converted items folder and trash the Streamclip-copied MPEGs. After doing this choose DVD with the Media Browser and drag the titles from the mounted disc image to the Video window. Now get the menu the way you want in the Video window by organizing the titles in the desired order and entering the text you want. You can customize the look of the menu by clicking on the menu thumbnail on the left. After extracting the videos from the mounted disc image you can unmount the disc image and trash it to free up space. That's because the MPEGs have been copied from it to the converted items folder. Just make sure you don't quit Toast because that automatically empties the converted items folder unless you changed the settings in Toast preferences. I have my Toast preferences set to never empty the converted items folder because I don't want to lose anything accidentally.
If you choose Save as Disc Image again using the MPEGs extracted from the disc image (as above) there will be no re-encoding. Toast will multiplex the audio and video and create the new menu. Once you finally have a disc image that has the menu the way you want when previewed in DVD Player, you can use the Image File setting in the copy window to fit and burn it to single-layer disc.

The temp file is already 7.1 gigs and I imagine it will be 8 before it is done. I still have 9.5 on the hard drive it is going to. I do not know and hope the image file will not be that big. It is only 3 hours and 15 minute long. I should have paid attention to the time to realize it was compressed and left it alone, just using the pal version.
So I learned a lot. Now to remember. It would be nice if there were a way to make a temp partition, or empty disc image of a certain size on the hard drive and have toast fit to that. You are right I would not be able to calculate the sizes in the custom section.
I am going to be afraid to dump the image, even if I see those browser files in the converted items. They seem to get written really fast for their size. I notice they are usually larger too. Is that correct? So once I see them I can dump the .toast image? Can you tell I am nervous about that but am up against the wall with space issue?
At least it forced me to do some house cleaning, and I learned that the size in finder window does not get updated reliably. Now I am motivated to install the new hard drive. Just worried about keeping all the apps installed and migrated properly. I made an error of having too many volumes, and having OS volume too small. I am afraid my 466 processor is too slow for Tiger. I am thinking of using Cc cloner for the migration. Maybe someday I can afford to upgrade the processor, and with new hard drive Toast will really cook.

Your idea about a temporary partition to force the single-layer compression is clever. Toast does have the ability to create temporary partitions, but Toast won't see that as an actual disc so it won't do what you've suggested.

The video is somewhat jerky, which could be expected, since toast uncompressed a file and filled in the blanks. Maybe this could be accepted but the sound is out of synch. Sound is ahead of video. Orginal menu items were left in as true segments or chapters themselves (they are the type that includes a clip). The good news is that it is in Ntsc format.
Another strange thing is happening. Computer is behaving as if I was still encoding. When I click on that converted file the mv2 in finder the spinning ball comes up for a minute before file details are displayed, and this happens everytime not just the first. I am in the view which shows the complete path and directory contents. I will try a re-boot.
So I do not know if I can fix the audio /video synch. Maybe running through streamclip again?
