Is DVD-lab Standard/PRO developed using official DVD Format Specification?
|
|
Yes, we are officially licensed for the DVD-Video format specifications from DVD FLLC (DVD Format/Logo Licensing Corporation) which is the official body behind DVD specifications (formerly DVD forum). We and all of our associates always use the latest official DVD specification books (1.13).
Furthermore we are also licensee of MPEG format under MPEG LA, LLC license. |
What is the difference between DVD-lab Standard and DVD-lab PRO
|
|
DVD-lab PRO is a full and mature DVD authoring tool without compromise. While with DVD-lab Standard we were always trying to look at the software through eyes of a (relatively) unexperienced user, with DVD-lab PRO we simply put the bar much higher. We listened to what advanced users wanted in a serious DVD authoring package and we doubled that. DVD-lab PRO is simply the most mature and full featured DVD authoring software in its price range.

What knowledge do I need in order to use the DVD-lab?
|
|
Both DVD-lab Standard and PRO are created with a quite wide user base in mind. It gives users a large flexibility and advanced features but it can also guide and teach relative novice user.
For example you have a Connection window where you can connect movies, menus, first play and title button. Even if you don't use it, it is fine, because it does the most common connection automatically as you are adding elements.
When designing menus you can just add some text, drop a movie to it from project window and that's it for basic functionality. However advanced user can create more elaborate menus where he can determine looks of the highlighted pattern, navigational routing, color map etc.
|
|
What OS are supported ?
|
|
The DVD-lab works on 95/98/NT/2000 and XP.
However what you must consider is the file system.
The minimal file system is FAT32 (you shouldn't use FAT16 anyway). This system supports files up to 4GB which is often enough. The best is NTFS on NT,2000 or XP which has no such limits.
If you use FAT32, make sure no single title (video+audio) is bigger than 4GB.
|
How about Linux?
|
|
We heard that DVD-lab works quite nicely under Linux using latest WINE, but we never tried it personally. |
What is it NOT? |
|
While we believe that DVD-lab will become absolutly the best bang for the buck, please don't try to compare it with the top production tools which cost many thousand dollars. Each piece of software has its own place and user base.
Also if you never heard about MPEG-2 and are not at least a bit familliar with the DVD creation process it would be best if you try first a DVD authoring tool which comes bundled with your DVD burner. |
Is the software recommended for commercial projects? |
|
It is strongly recommended that professionals who are getting paid for their commercial work use a commercial grade software. There are few industry standards for making DVD's such as Sonic Scenarist or Apple DVD Studio Pro. While nobody will stop you from using our low-cost solutions for commercial projects, it is not advisable. Once you invest a lot of money and time into making your commercial project, it doesn't make sense to suddenly go "low-cost" on the last, but equally important step such as authoring DVD.
|
Is the output guaranteed to play 100% on all possible players. |
|
A very honest answer is that we can't guarantee 100% playability unless we do test all players ever build on all kinds of files, which is not possible. At this moment our own estimation would be a 98% players compatibility (PRO version), where we put a "safe" margin of 2% of players that may have problem playing the authored DVD's for whatever reason. Please note, it is an estimation, not guarantee. We are trying to improve this ratio constantly. If you find a player that has an obvious problem playing the authored disk (excluding disk related defects and problems) please let us know the type and model.
Note: No actual software would offer 100% compatibility. If you need to create disc that may be guaranteed to play on all possible players it is strongly advisable to actually have it made by a professional and experienced authoring studio with a good feedback from customers. They will try to eliminate the compatibility issues between different players by detailed and experienced supervising of the whole authoring process from capture, encoding, authoring (using Sonic Scenarist, the standard for commercial DVD title production) to the testing and final glass master.
|
Is the software recommended for education? |
|
Yes, it is highly recomended for education.
Especially the PRO version is probably the best choice for any advanced learning. It has all the important aspects of DVD specifications shown in accessible and transparent way. Studenst can learn about DVD structure, DVD commands and other aspects of DVD creation using user friendly software. This knowledge can be then later used for understanding high-end systems such as Sonic Scenarist. In fact DVD-lab PRO is the perfect jump-start to learn serious advanced DVD authoring because the gained knowledge is general, not specific to DVD-lab.
|
|
Why there is no MPEG Encoder bundled?
|
|
There is a good reason for that:
First of all it push the software price up. Secondly, you probably already have some encoder bundled with your DVD burner. And at last, didn't you realize that most of the consumer software uses the very same medium quality encoder ? So if you have two Video or DVD applications you already probably paid for the same encoder twice.
At this stage we believe adding MPEG encoder will be just a "feature" without the real benefit of it but with the price tag. |
|
What Encoders are recommended?
|
|
Many people use TMPGenc because it is non-expensive, relatively fast and let's you really tweak the mpeg properties. Also it allows you to resize or resample the clips which is a handy bonus.
Another choice is CinemaCraft encoder which is one of the fastest yet it produce quality clips, Mainconcept (often bundled with authoring and video editing applications), Canopus ProCoder and few other popular choices.
At the end, the choice is yours, there are more quality hardware and software solutions available every day.
|
|
Is there support for 24fps and Pulldown?
|
|
Yes. DVD-lab support all files DVD specification allows. |
|
What about multiple audio channels?
|
|
DVD-lab PRO has full support for 8 audio channels. DVD-lab Standard support only one audio channel.
(By one audio channel we understand a single audio file that can be stereo or 5.1) |
|
What is Full D1, Half D1 etc..
|
|
The full D1 is the video frame 720*480 (NTSC) while Half D1 is 352*480. A commercial DVD's are mostly using Full D1, while amateur may decide to go for Half D1. Of course the Full D1 has better quality, but the benefit of the later is in the size, While a reasonable bitrate for Full D1 is 4000kbits and higher, Half D1 looks fine with 2400kbits. That means you can put about 4 hours on one DVD in a S-VHS quality. It still looks good on a TV.
However there are some things to consider. For best compatibility you shouldn't mix Full D1 and Half D1 movies on same DVD (DVDlab will issue warning if you do ). DVD players will assume all videos are the same size as the first one and then the picture gets really funny.
With menus it is more blury but the rule of thumb is use always Full-D1 menus. |
|
To what extent can I create menus in DVDlab?
|
|
DVD-lab offers a full featured menu designer. If you dig inside you will realize that the menu designer is capable of creating any type of menu imaginable and with lot of appeal. You can combine Buttons, Bullets and Frames from the template bins, with text, video frames or other images. You can drag & drop any video frame from Preview to menu or simply add a chapter point frames with the chapter tool. Also you can add any graphics by either adding it to the Video & Audio bin (project specific) or add it permanently to any other bin (Backgrounds, Buttons, Images).
Here are more advanced features of the menu designer.
- You can change color not only of text but also of any graphical object like buttons, frames or video stills.
- You can add a drop shadow or glow to any object
- Active object can be visible, invisible in normal state, invisible in selected state or always invisible. This will enable you to create any types of highlighted overlays. For example a frame around a text or text underline which will be visible only when the button is selected
- You can use Group HotSpot to define which objects belongs to a single button or define a different hotspot region of the button. Together with the visibility option this gives you the total power.
- Each active object can belong to one of three color group and you can select the highlighted color mapping for each group separately
- You can do your own navigation routing if you want (what button is selected when user press up,down,left, right on his remote)
You have really the power to create truly interesting menus. For an interesting idea see this tutorial.

|
Can I create DVD without movie, just menus?
|
|
Yes, but you need at least one video. You can create very short one as a First Play or you can get some dummy, but you need at least one video. There is a technical reason. |
|
How to create motion menus?
|
|
You can add motion menus, however normally you have to prepare the video stream outside DVD-lab in your favorite editor. There are many ways to create motion menus, some are described in this quick tutorial.
Since 1.3 (see history), you can render motion menu and motion thumbnails directly in DVD-lab. See more here.
Because the looping of a short video is a bit annoying you should consider a motion menu which is about 40 - 60 seconds or more.
|
|
Can I add audio to a still menu?
|
|
Yes, you can add any supported audio clip ac-3, dts, wav, mpa...
Just simply drag the file from Asset bin to the particular menu. The sound will repeat in a loop. You can also let a movie start when the loop is finished. To do so, change the Timeout from inf to 0 and enter the Button number in the Force Activated Btn. (This is the number which is near a left top corner of button if you have Show Button Number set to ON)
The mpa or ac3 audio doesn't take much space (you can have few minutes of music in few mega bites which is nothing in comparison to the DVD space). |
How to create Menu Transitions? |
|
From Wizard button on main toolbar select Menu Transition. Select which menu is "From", and what is "To". Pick one of the 50 transitions and click Proceed. The transition clip will be generated and positioned between the Menus.
If you change something in the menus you have to also Rebuild the transition. Right click on the transition in COnnection View and select Rebuild Transition. You can also change it to any other transition type.
|
|
What is Auto-Action on button?
|
|
The link will be executed on Auto-Action button as soon as user navigate to it with his remote without him pressing the enter button. |
Why Elementary streams? |
|
In order to be able to have the best possible DVD-compatibility, DVD-lab (as most professional tools) works primary with Elementary streams. The Video and Audio are separated and this allows the Compile process to multiplex the vob exactly as required. This also allows adding other audio types such as AC3 or DTS and in future this is the base for multiple audio streams.
|
Why no preview with audio? |
|
The main reason are the Elementary streams (see above). DVD-lab can't preview together the elementary video and audio in its preview window. In fact this is almost impossible to do in realtime without a special syncing hardware or without some prior pre-compilation. Such attempt in software will most likely produce a false sync problem - something which is far worst than not hearing audio at all.
The job of the Preview window is to set chapters and to locate some video stills you can then use in menus. To hear audio for this task is not essential. You should insert chapter points to a video clues such as scene change. In fact since the chapter points in DVD are bound to video I-frames you won't be even able to add chapters with any big precission to audio clues anyway.
|
|
How can I preview audio in DVD-lab?
|
|
You can play mpa or wav audio by simply double-clicking on it or dragging it to Preview window. This is done through Windows Media Player and as such it may not work on all computers. |
|
How can I preview video which is not yet added to the movie (it is still in Asset bin)?
|
|
You can play video by simply double-clicking on it or dragging it to Preview window.
Once the video is added to the Movie Title, anytime you select the Movie window it will appear also in the Preview. |
I can hear the audio on DVD in a software DVD player (ex. PowerDVD) but not in my standalone DVD player. What is the problem? |
|
It is most likely problem with audio setting in your standalone and using mpeg audio. MPEG audio is not a standard in NTSC but all DVD players now support it. However some DVD players expect to play AC3 or PCM audio as default and for mpeg audio you have to set them to analog or 2 channel mode. Some players can do this automatically without any user interaction.
Insert the disc to your standalone player, start playing it and then press Setup on remote. You will get to menu screen and then navigate to Audio section. Try various output sections. For example on Toshiba players you have Bitstream (default), Analog2Ch and PCM. The Mpeg audio play only through Analog2CH on this DVD player.
Again this depends on the player. Most player can play MPEG audio through default settings, but for some of them as the above you have to change the output.
(thanks to rixware for this tip)
|
I can't hear the audio on one movie, while other movie plays fine. |
|
Make sure that you use only the same audio type in the audio channel for all movies. The DVD-lab Standard is a single VTS compiler and the audio type can be changed only for whole VTS, not separately for PGC's (Movies).
DVD-lab PRO is a full multi VTS compiler where movies can have different audio tracks in different VTS.
|
I can't hear the audio on the DVD (or one movie) at all but if I play the VOB file directly in Windows Media Player or PowerDVD, the audio plays fine. |
|
First make sure it isn't the above problem.
The audio channel properties for DVD are set in IFO files. Sometimes the compiler may not find the proper audio header if your file comes from different sources or you use VOB as input. While the audio is muxed in the vob fine, the compiler doesn't write the audio properties to the IFO. In the 1.2 version a new option was added: Force Audio to all movies. This will check the IFO files and eventually force the audio settings there if it is missing. Also you can change it manually after compile in the menu Tools - IFO Editor - Audio |
I have input VOB file with 2 audio channels but DVD-lab recognize just one of them. |
|
After the compilation, go to menu Tools - IFO Editor Audio and set number of audio streams to 2, then change the correct properties in the second audio channel. (version 1.2 and newer) |
What is the difference in the Multiplexer engine: Fast and Flexible (Alternative) |
|
The original "Fast" multiplexer can work on most DVD compliant files and it can use MPEG system files directly without demultiplexing. However if the input file has some errors such as missing frames or non standard GOP structure, the result DVD may stutter. This is often an indication that something was wrong with the files.
The enhanced "Flexible" multiplexer was added in 1.2 to be able to process all kinds of files without stutering during playback. You have to remember that if your files are not DVD compliant or have some errors this will not make them compliant or error free. They may be muxed to be playable without stuttering, but the DVD will still remain non-compliant or with the errors.
The error checking and fixing didn't come without penalty so the "Flexible" muxer needs at least 2x more temporary space than the "Fast" one and also the compilation will take bit longer.
If you planning to use "Flexible" multiplexor then the best is to use Elementary streams.
|
What if I have problem with video or audio on the compiled DVD? |
|
Because DVD-lab doesn't re-encode files, it is important to check if your video files are actually valid for DVD. In DVD-lab you have a Parse MPEG stream command (works only on elementary streams)
The GOP structure is important for smooth playback on standalone DVD players. DVD ready video should have all I, P and B frames. The GOP structure for NTSC is IBBPBBPBBPBBPBBPBB (max number of frames in GOP 18) and for PAL it is IBBPBBPBBPBBPBB (max number: 15).
If your GOP structure have only I and P frames then you should set the standard structure (as above) in your encoder.
|
|
What is Compile on background?
|
|
You can compile the large DVD on background. That is you are not stuck with an endless progress-bar, instead you see the progress in the Compile bar and you can do anything other on the project - you can even work on a totally different project. You can even close DVD-lab during compiling and the compile process will detach itself and continue to run in a new window. |
What type of audio should I choose? |
|
While many DVD players are said to support WAV, AC3, DTS and MPA this isn't true. From spec the NTSC players support AC3 but MPA is optional. MPA often works but may not always on players which are true to the specs.
The PAL players supports MPA and AC3 is optional. Probably most PAL players will play AC3.
If you use DTS, then the DVD will be non-compliant by deffinition (but it will probably play fine). The specs asks that AC3 should be first audio channel and then you can use DTS. |
How to transcode audio to AC3? |
|
With the build in audio transcode tool you can call other audio encoders with commandline settings.
One example could be the free BeSweet, but please make sure you understand the risks. BeSweet used ac3enc is not tested, nor licenced from Dolby and that means few things: using it may be illegal since you are using software which didn't pay royalties for the Dolby patents (you may be liable for this) and also nobody will tell you for sure if ac3 created by beSweet is really up to specs.
Anyway, if you still want to try it then here is example of the command line you can enter to the Audio Transcode in DVD-lab:
External exe should point to BeSweet.exe and the commandline should be exactly:
-core( -input $INPUT -output $OUTPUT ) -azid( -n1 -c normal -L -3db --maximize ) -ssrc( --rate 48000 ) -ac3enc( -b 224 )
...also select Output is ac3 for the correct extension.
You can change the bitrate in the last command in ac3enc, here is 224kBps.
Anyway, for any serious dvdmaker there are number of licenced ac3 encoders, the simple 2 channel is not expensive and some software may have it already build in.

I have problems recording DVD+RW.
How to format or erase DVD+RW/-RW properly?
|
|
The DVD+RW as oposite to DVD-RW doesn't have to be reformated every time you record a new data.
When you buy blank DVD+RW it is not formatted (the data side is shiny). A recording software needs to FULLY format such blank DVD+RW at least once before the data can be recorded. Because the formatting is long process (about 20 min per DVD) the burning software usually formats only the part that is really needed to hold data. You recognize such formated part as darker in color. Next time if you write less data then the disc doesn't have to be formatted, if you try to write more data, the remaining unformatted part will have to be again formatted by the application.
Once the part of DVD+RW is formatted it doesn't have to be ever formatted again to write new data over it. Of course a quick format can be then done which will simply erase the previous data but that is not necessary. This is different from DVD-RW. DVD-RW has to be erased each time you want to record new data, but it doesn't have to be erased when you get a brand new blank - you can directly write to it.
This of course causes a lot of confussion. Especially with new combo drives able to record both +/RW and -RW.
If the DVD+RW disc is not formatted or the data to be written are larger than already formatted part, DVD-lab record module as any other applications will after clicking Write start first formatting the needed part. You will see no action for many minutes. Only then the data can be written.
The far best way to deal with DVD+RW media is, when it is brand new, simply run the software that comes with your recorder (Nero, Roxio, Veritas..), select Format (some applicationss call it boldly Erase to confuse people even more) and choose Full Format (or Erase if you will). This will fully format the DVD+R in about 20-30 min. (the data side will appear darker on whole area). Once you have such DVD+RW you can then simply use DVD-lab or any other software to Write on it again and again without use of additional formatting.
Note: The Erase/Format button in DVD-lab recorder works as a Quick format - it quickly erases all data on DVD+RW, but it doesn't fully format whole disc if it is blank. As that it is not necessary for +RW discs. Only Write will fully format the disc if needed and user will see no action for many minutes.
DVD-RW as mentioned before is different. The blank DVD-RW is ready to be written, no need to wait to format the disc. However DVD-RW needs to be closed after writing which adds to the total writing time. (More data you writte, less it takes to close DVD-RW)
When you want to write new data on the DVD-RW you have to Erase the disc. In DVD-lab recording module press the Erase/Format button. It takes few minutes.
Writing few data to already fully formatted DVD+RW is then faster than to DVD-RW because the -RW needs additional time to close the disc and you need to erase it each time you want new data to be written. So for testing purposes the +RW format seems better overal. However when it comes to +R/-R media then the -R seems to have advantage of broader support between hardware players and the -R blanks can be obtained much cheaper.
If you are still confused, don't worry. One day this will all become clear...
