WHEN CONVERTING MICROSOFT POWER POINT 2007 to DVD THE TEXT BECOMES BLOCKY ALMOST TO WHERE I CAN NOT READ IT
SUMMARY:
POWERPOINT WILL NEVER CONVERT TO DVD NICELY EXPECIALLY WHEN YOU HAVE BEEN VIEWING THE POWERPOINT AT A SCREEN RESOLUTION GREATER THAN DVD (720*480). FOR EXAMPLE, I HAVE A SCREEN 1920*1080 AND MY POWERPOINTS LOOK GREAT. MY POWERPOINT EVEN LOOKS GREAT AT 800 BY 600. BUT WHEN I CONVERT IT TO DVD, THE QUALITY OF MY PRESENTATION IS DEGRADED GREATLY. THIS IS BECUASE OF THE LOW QUALITY OF A DVD. WE HAVE BEEN MISLED TO BELEIVING A DVD IS GREAT QUALITY ALL ALONG. DVD IS GREAT QUALITY NEXT TO A ANALOG TV OR THE STANDARD TV DEFINITION OF 10 YEARS AGO (YEAR 2000). YES DVD(20+ YEARS OLD TECHNOLOGY) IS GREAT NEXT TO VHS(30 YEAR TECHNOLOGY) BUT NEXT TO A MONITOR WHICH HAS A 800*600 OR GREATER SCREEN OR A TV WHICH HAS HD OR 1080P HD. DVD QUALITY SUCKS. DVD TECHNOLOGY IS OLD AND ANY COMPUTER WHICH HAS BEEN MADE IN THE LAST 5 YEARS HAS A SCREEN RESOLUTION WHICH IS 2X BETTER THAN DVD TECHNOLOGY.
DETAILS:
Recently I have had major problems with trying to burn a power-point
Or print screens into DVD and have the text to remain in a readable
format. I used several techniques and several different types of software
to try and accomplish this goal. The final result was that this type of
conversion was never going to look good because I was working with
DVD technology.
The DVD format can not support HD (high definition) video. DVD format
will accept 4 dimensions (720*480, 704*480, 352*480 and 352*240). DVD
also displays the presentation in either a interlace or progressive scan. The
new conventional terms used for this is 480i(interface) or 480p(progressive).
The two display styles differ by how they display the content from top to bottom;
Interlace(i) displays every other line than goes back to the top and fills in the
opposite, progressive(p) is the newer standard and shows every single line in
consecutive Order from top to bottom (hence 1080p).
Another factor which has caused me to fail(not by much) is the difference
between the Wide Screen and default screen display. Wide Screen has a ratio
of 16:9 and the default screen display has a 4:3 ratio. Why could this be important
when trying to represent alphabetical characters and sharp graphics? Both aspect
Ratios can be represented in every resolution above. But the difference
Lies in how the pixel are represented. 16:9 ratio represent the same viewable
area using a wider rectangular shape where as the 4:3 ratio represents the
same content more like a square. This did not cause the most aggravation but
I figured I should at least mention this fact.

THE DVD burning software should also burn the dvd using the MPEG2 standard.
Which is found on most recent software versions. MPEG2 maintains better quality
in the final burned dvd and is now the defacto standard. Another thing I noticed
while attempting to burn the DVDs is that the final DVD Produced jumpy screens.
I used and external DVD when doing my original image Burns and saw this problem.
I even turned the external dvd flat(horizontal) from its original
Position of vertical and it still jumped. But on my final attempt I placed it horizontal
On the desk on its four rubber feet and it appeared to correct the problem.
QUESTION I ASKED?
IS THE final DVD( product) files on the DVD DIFFERENT BETWEEN THE different
Softwares after it has been burned?
All files with the MPEG2 are standard with the BUP, IFO and VOB extensions.
Software I attempted to use through out this research:
PINNACLE STUDIO 11
WINDOWS 7 DVD MAKER
CAMTASIA 5 and CAMTASIA 7 (used to capture screens, camtasia 7 is great!!!!)
NERO 10
ROXIO 9 AND ROXIO 10 (it burns good DVDs although the options for DVD Menus are not that good)
AVS DVD Player and Converter (I did burn one DVD but the quality was still bad)
Another thing to remember if your screen is running in full HD (1920*1080)
And you capture the screen at this level YOU SHOULD BE IN GOOD SHAPE
AS YOU EVENTUALLY BURN THE DVD AT 720*480.
But if you start with a resolution of something like 640 by 480 and go up
To DVD quality when you burn the image. Or if you do a screen capture
And use the zoon features in Camtasia and zoom into a picture with
A 640 by 480 quality. You quality will be degraded. So be sure start out
With the highest resolution for your screen captures, your pictures (png and
Jpeg and jpg). If you start out with a very high quality and use the zoom
/crop features in camtasia you should maintain good resolution through
Out the process
BOTTOM LINE
WITH PINACLE (THE FINAL PRODUCT(dvd) BECOMES PIXELED)
WITH NERO 10 (THE FINAL PRODUCT(dvd) BECOMES PIXELED)
WITH WINDOWS DVD MAKER (THE FINAL PRODUCT(dvd) BECOMES PIXELED)
AVS DVD MAKER (THE FINAL PRODUCT(dvd) BECOMES PIXELED)
WITH ROXIO MY DVD, even though it appeared better and played
in all Dvd Players, it still appeared pixilated on my computer.
When I played it in the DVD on a older TV, it appeared respectable.
My three TV’s are 32inch or smaller and they all have been purchased
More than 5 years ago. None of them are HD (that I know of). But
When I played the same video using Windows Media player, the
Default player size is small and the video content again looks respectable.
But when I click on the full-size button in Windows Media Player the
Content becomes pixeled(boxy) again. I monitor sizes have resolutions
Of 1600 by 1200 and the other is 1920*1080. The content plays In
Full screen with black background on either side. In other words the
Picture is not distorted, the media player simply back fills with a black
Background and the CONTENT becomes pixeled at these resolutions.
TO RECAP
===============
DO NOT BURN CONTENT TO A DVD and EXPECT TO SEE AN
EXCELLENT PRESENTATION. DVD is limited to a screen
Size of 720by480 resolution. So if you show your burned DVD
On a screen size larger than 720by480, or you show your content
On a projector which uses a display size of 1024by768, or
You attempt to expand your media player to a resolution
Greater than 720 by 480 your content is going to look bad. NO
MATTER WHAT YOU DO.
AT THE END OF THE DAY 720 by 480 is 720 by 480.
DVDs will never be able to show crisp text that a blu-ray
Format can support or a High Definition can support.
To note: Your computer screen will always display DVD
Content more crisper than an older TV. Your computer
Screen uses newer display technology.
So next time your vendor hands you a DVD for the video it
Created for you. Ask for a Blu-ray or the original HD
Format (1920*1080), expecially if you plan to display
this video on a newer TV with HD resolutions or a projector
with 800 by 600 or better. In other words always start out
with the best quality video the vendor can give you, your
display technology will dictate what you can display. If
you do not have a blu-ray or you do not have DVD burning
software go buy it or ask your vendor to give you a DVD
and also the original digitial video created by the computer
in HD (1920by 1080). Lower is fine too. Just not lower than
the lowest HD resolution 1280*720 (HD DVD, Blu-ray).
To note: IMAX is 10000*7000

ANOTHER NOTE(SOMEONE RECOMENDED) IF YOU REALLY NEED TO CONVERT A POWERPOINT TO DVD. CONVERT EACH POWERPOINT SLIDE TO A JPG OR PNG FILE, NEXT OPEN A DVD BURNING SOFTWARE AND DRAG AND DROP EACH IMAGE IN THE DVD BURNING SOFTWARE ONE BY ONE. I DID NOT TRY THAT BUT I WOULD IMAGINE YOU WOULD WANT THE PICTURES TO BE IN THE PROPER DVD RESOLUTION BEFORE DROPPING THEM INTO A DVD PROGRAM SO THAT YOU HAVE LOSSLESS QUALITY WITH THE TEXT.
DVD FORMAT IS OLD AND LIMITING.
