DVD Authoring Tools Offering 4:3 and 16:9 Aspect Ratio |
|
|
I'm new at DVD authoring so if my question below exposes a serious
misunderstanding about the subject, please excuse my ignorance... I'm
learning
Just a quick question for those lurking on these boards about what DVD
Authoring packages are recommended that will provide MPEG-2 outputs of 4:3
and/or 16:9 aspect ratio.
Our TV is a normal screen (not 16:9) and we'd need letterbox (4:3) output
for those shows we record on our ReplayTV and then copy to DVD. I've
searched the internet for all the DVD Autoring packages out there and it
seems only a few actually provide this output capability.
Can any of you recommend which package works best for you?
Thanks!

I don't work for them, but when you get a chance, you might drop by the
Adobe site. They seem to have several .pdf files about Video and DVD
making.

Authoring packages use an aspect ratio of the MPEG2 track you have. Some of
them, like Sonic Scenarist also allow to set aspect ratio for menus, so you
can create 16:9 menus. You should not record 16:9 as 4:3 letterboxed as
space is wasted to encode the unnecessary information. It's DVD's job to
letterbox the 16:9 video if necessary.
As for the authoring software, depends on your other needs. My standard
software now is TMPGEnc DVD Author. It keeps an aspect ratio of the original
MPEG2 track, so depending on what you feed it with, the result is either 4:3
or 16:9. Anyway, even if your SW screws up this information, it can be set
up after authoring the DVD with IfoEdit.
One more thing, Some people were complaining here that some authoring
softwares were re-encoding DVD-compliant video tracks. Make sure your SW
does not do this or that this feature can be turned off for compliant video
tracks. |

Hi,
Is there a 'list' of the low end packages that actually create the IFO files
with the correct data for letterboxing?
From trying quite a few packages ( including Sonic DVDiT), even if you have
a 'squeezed' 16:9 video, they all leave the mastered DVD so that on a 4:3 TV
the image is full screem and not in a letterbox.
Most low-end packages will create 16:9 via cropping/resizing of the 4:3 DV
footage which plays back on a PC correctly in widescreen.
Is is really that difficult for them to make the IFO file correctly reflect
the video stream?

Just checked the IFO files with IFOedit and the letterbox option for the
16:9 was not enabled. Looks like this is the problem area (many low cost
packages do not do this).
Thanks for the feedback.

I tried just a few SW and they worked as expected. How do you create your
MPEG2 tracks? When you play them, do they have the ratio you expect them
to
have? If not, you can fix it with programs like restream before authoring
the DVD. It's just a matter of setting one attribute of the MPEG stream,
no
re-encoding. DVD authoring SWs are not expected to mess with it. If they
do,
you can always fix it with IfoEdit. Just open a corresponding VTS_*.IFO
and
change the attribute of the track to 16:9, save it and you are done.
The important thing is an original aspect ratio. You should not change it.
Changing it either way will always lead to losing information, because you
have to cut either from top/bottom or from sides. There is no way around
it,
if the picture should look normal. If you record in 4:3, I see no sense in
making 16:9 DVD from it. Keep it 4:3. You'll get complete information on
4:3
TVs and 16:9 TVs can handle this situation in some way, too.
If your DV footage is 16:9 letterboxed to 4:3 (bars are part of the video)
_then_ you should remove the bars and encode the rest as 16:9.
