DiscWelder seems to only like 96/24 MLP files...
No biggie, I'll just have to leave out tracks from Michael McDonald's 'Motown' on my mix discs.

What software might there be for creating a dvd-a (preferably even a dual-layered disc of dvd-v and dvd-a) from audio_ts and video_ts folders...on a Mac?
I'm guessing discWelder will create an audio_ts folder, and author a disc with it, but will it take an already existing audio_ts folder and burn that properly? The Mac version will not create dual layered dvd-a/dvd-v, but would it burn both if both folders already exist?
DW can create .dim image which is practically iso. Just remane the dim to iso, mount it with eg. Daemon Tools and in this way you can have access to the Audio_ts folder....Will discWelder create an audio_ts folder and, as an optionally separate procedure, burn a dvd-a with that folder? Can you create the first, file it away on a hard drive, and subsequently burn copies as needed later with dW? Can you take an externally obtained audio_ts folder (i.e. one that dW did not "build") and have it author a disc? Or is it utterly a one-shot deal, if you want to generate another dvd-a disc later you have to have all the individual parts/files around?
I'm confused by all this and I want to know if it's worth the bother to go in the dvd-a direction; it means a new player, new authoring software, less storage per disc, no automatic way of creating chapters. I'm not going to compound things further by getting a whole new computer to do the job.
I was assuming that the contents of an audio_TS folder is what a dvd-a uses. Is this wrong? Does a disc image file contain audio_ts and/or video_ts folders?
In the video world you can create a video_ts folder and then burn a dvd-v with that folder (with the proper authoring software)--two different processes.
Does the dvd-a world work the same way? Will discWelder create an audio_ts folder and, as an optionally separate procedure, burn a dvd-a with that folder? Can you create the first, file it away on a hard drive, and subsequently burn copies as needed later with dW? Can you take an externally obtained audio_ts folder (i.e. one that dW did not "build") and have it author a disc? Or is it utterly a one-shot deal, if you want to generate another dvd-a disc later you have to have all the individual parts/files around?
I know the only available Mac version (at least I think it's still available, the Minnetonka website seems to indicate this) is not able to do anything beyond standard stuff (no dual layer, no automatic universal disc translation). If I were to make a separate video_ts folder can I have discWelder author a universal disc using my supplied video_ts folder? Or is authoring a universal disc something completely different, no matter the content, and beyond this programme's capability? What would a dvd-v or dvd-a player have to do with the other player's dedicated data/layer/zone?
I've tried to ask Minnetwonka this but they haven't answered my email.
Very interesting and helpful. Thank you!!!!
Correct....You cannot take a pre existing Audio_TS folder into DiscWelder, as far as I am aware - I might be mistaken here I am fairly certain this is correct.
AFAIK +R must be used for dual layer discs because the layer break point is not adjustable in -R DL.So to sum up:
1. It looks like DW Bronze creates an AUDIO_TS folder but within an image file. I have to assume that it then burns this image file appropriately to a drive to make a DVD-A, either separately or sequentially. BTW, does -R vs. +R have a bearing on things? Does the type of DVD burner have a bearing on things?
You mean on Mac?2. If I were to try to make a Universal disc: assuming v and a contents are the equivalent and the appropriate players look at the appropriate data, and assuming I use DW-Bronze to create the AUDIO_TS folder and something else to create the VIDEO_TS folder (DVD Studio Pro), what I need then is an app to take the two folders and author a universal disc, or create a relevant image file and then burn a universal disc, something that I guess DW-B will not do.
3. If I have a correctly constructed AUDIO_TS folder I still need an app that will author a dvd-a from it, something that DW-B will not do if that AUDIO_TS folder doesn't come embedded in an audio-only iso file, and something that Burn should do but doesn't.
OK, after trying several apps and several possibilities and much rewriting to try to make my questions as clear as possible...
Neil: This is going to get somewhat complex - but please do not let that put you off. Me: I think I understood some of it.
1 - The Audio_TS is indeed where the files for DVDA reside, but with image burning applications you need to be certain that it will make a playable disc, and not simply a data disc with an Audio_TS folder on it. I expected this. I'm assuming there is some sort of flag to tell a player what kind of disc it is and that the authoring software, like Toast, knows to set such a flag appropriately. The problem is finding such apps that will do the job on a Mac...
2 - The DVD-A world does work in the same way, but with added steps if there is to be a Video_TS. these titles are really 2 discs on one piece of plastic, as both title sets (Audio_TS & Video_TS) need to be authored in different applications, with the resulting Video_TS needing to be imported into the DVD-A authoring software. Now, does this mean that the theoretical flag I mentioned has a setting for DVD-A, DVD-V, and DVD-Both? Does it also mean that to make a Universal disc you need to burn the disc in the equivalent of 2 "sessions", one to burn the VIDEO_TS folder and one to add the AUDIO_TS folder, or vise-versa? As a side note, I think we need a distinction between "construction", i.e. creation of the whatever_TS folder and "authoring", i.e. the taking of that folder(s) and burning a disc such that the intended player will do the right thing with that data.
Discwelder is an abstraction layer tool, meaning most of the interesting stuff is locked away & inaccessible. It does not create an Audio_TS folder on your HDD - it creates an image file instead (.dim) which can safely be renamed as an ISO file & then you can extract the Audio_TS from there. You cannot take a pre existing Audio_TS folder into DiscWelder, as far as I am aware - I might be mistaken here I am fairly certain this is correct. I'm not sure what you mean by extracting AUDIO_TS from the image file. If you mean storing it for later burning, A) I would think I would just store the whole image file (what else would be in it? I would think there would either be no VIDEO_TS folder or just an empty one), and B) this means that you can subsequently specify an existing image file for DW to burn. If the latter (hopefully), does it have to be a DIM? Can I specify an ISO (or change an ISO to a DIM) that has both _TS folders, or in other words, does the presence of a VIDEO_TS folder within an ISO (or DIM) cause a problem for DW?
I managed to find and downloaded a surround sound iso that has both AUDIO_TS and VIDEO_TS folder content. I tried Sourceforge's Burn app to try to make a universal disc out of this iso. On one Mac with OS 10.5, external burner, it tried to burn but would fail (communication problem or some such) and on another Mac with OS 3, both internal and external drives, it would immediately stop with "device not supported for this burn operation" no matter the drive. On the former Mac I also tried to make a DVD-A using just the AUDIO_TS folder and that resulted in the same error message. I know at least the VIDEO_TS folder has valid data as I could burn that folder with toast ("dvd-v from VIDEO_TS" option.) Unfortunately there is no "dvd-a from AUDIO_TS" option. If DW Bronze cannot accept an external AUDIO_TS folder is there any other Mac app that will take an iso file containing dvd-a data and burn it properly?
You can take an existing Video_TS folder and merge it into a discwelder chrome project though, but to satisfy specs you should "point" all VTS titles from the discwelder project window. Not applicable; chrome isn't available for Mac. What's a VTS again?
Authoring a universal disc requires at the most basic - and spec illegal - WaveLab 5 and up. This will create a valid Audio_TS and will allow you to import an external Video_TS but will not allow you to link into any of the Video_TS content. The downside here is that this means unless you reset your player from AUDIO to VIDEO mode, you will not be able to access any of the video content (this goes back to how players work - we will get there, honestly). It's very basic, but essentially functional, and WaveLab 7 will be available for the Mac OS. OK, when will WL7 for Mac be available and about how much would it be?. Secondly, assuming that any universal disc I might make would only contain dvd-v content that would mirror, albeit with video and with lossy-compression sound, that which is found on the dvd-a part, I don't see a problem. If a regular dvd player will only, and automatically, find the VIDEO_TS folder and play that, and a dvd-a-compatible player will only, and automatically, find the AUDIO_TS folder ad play that, I don't see resetting being an issue, so long as the appropriate player will find the appropriate data. I would think the only time this would be a problem otherwise is if you have a dvd-a player but don't have the facility to connect it to an analogue audio component amplifier and only have a coaxial or optical connection and need to manually tell the player to "go video" (as I've gathered, dvd-a does not allow you to send the uncompressed digital audio to an amplifier), or indeed you have video and audio content that is unrelated.
discwelder chrome really does assume that you know what you are doing if you want to create custom menus. Generated screens work okay though, but you may find trouble in making certain links work unless you know the specs & the limitations. Again, chrome does not work on a Mac. As far as menus are concerned, I may make simple ones for any dvd-v portion I may make, otherwise for both dvd-a and dvd-v content I'm going to make most all track/album access very simple and for dvd-a just have tracks. With DW bronze I'm not sure I have any menu control at all anyways.
creation of slideshow titles where you can use a single image for each track and set track markers in the stream. With Scenarist, this cannot be done & if the music is segued or a live album, you must use low bitrate MPEG-2 streams. DVD-Lab's issues are the 2 big bugs....
A - you simply cannot create a title with more than at most 6 VTS or it will fail, and
B - if creating an Audio-Only title instead of a slideshow, you get gapping between tracks. It sets the cells as non seamless, meaning that despite the audio being one contiguous stream, it sets flags for non seamless playback and some players will then empty the buffers instead of continuing playback. This can be fixed in PGCEdit though, which is donationware. Still talking dvd-v here, I did try slideshows a couple of times a while back. I noticed that changing from one slide to the next caused a gap in sound and I assume this is what you were taking about. As such I probably wouldn't bother with them. But I'm not sure. It will depend upon how small I can make the video MPEG file information that would run with simple still images along the track as the audio played. I might do a slide show with just one image and have whole albums as one track/chapter, making gaps a non-issue, but this is assuming disc players will be able to fast forward/backward through the resulting audio if so desired, something I'd have to check.
As for "Audio-Only title instead of a slideshow", I'm not sure what you mean. I just checked and DVD Studio Pro shits the bed if I try to build a VIDEO_TS folder and there's no corresponding video of any kind to go with the audio. I'm not sure where the "gapping between tracks" comes into play. But then again, I've never set up even a regular video/audio track with sequential segments wherein a short pause between them was an issue.
Finally in the hybrid/universal stakes, we have Sonic's DVD-Audio Creator. Way out of my price-range, even if it was available, as you said. I am continually surprised that A) as Sonic seems like the audio equivalent of something like DVD Studio Pro that it would cost several times what the latter does, and B) that Mac does not keep up the equivalent software of their own despite the dvd-a being a dying format. Aside from the possibilities of what Blu-ray has to offer in this area I'm surprised there is nothing that is supported.
Now it's time to talk about players & zones... Got it.
So to sum up:
1. It looks like DW Bronze creates an AUDIO_TS folder but within an image file. I have to assume that it then burns this image file appropriately to a drive to make a DVD-A, either separately or sequentially. BTW, does -R vs. +R have a bearing on things? Does the type of DVD burner have a bearing on things?
2. If I were to try to make a Universal disc: assuming v and a contents are the equivalent and the appropriate players look at the appropriate data, and assuming I use DW-Bronze to create the AUDIO_TS folder and something else to create the VIDEO_TS folder (DVD Studio Pro), what I need then is an app to take the two folders and author a universal disc, or create a relevant image file and then burn a universal disc, something that I guess DW-B will not do.
3. If I have a correctly constructed AUDIO_TS folder I still need an app that will author a dvd-a from it, something that DW-B will not do if that AUDIO_TS folder doesn't come embedded in an audio-only iso file, and something that Burn should do but doesn't.
4. If I am sounding too thick for the public forum please tell me I should take this all to a private message... :slap:
