BEST VIDEO WUALITY SETTINGS

Post by johnalig »

Here's my question.

I am converting all of my old VHS Home Video's to DVD. I normally make 2 DVD's per VHS Approx 2 hours) a DVD full capacity is around 4.7 GB. After capturing the 1 hour, Ulead shows the DVD usage of about 2.8 GB (and the picture is so so) with still extra room on the DVD that wasn't used. Is there a way to tell Ulead to use the full DVD space.

System
AMD 3200
1GB RAM

Ulead shows
NTSC drop frame (29.97 fps)
Microsoft AVI files
24 Bits, 720 x 480, 4:3, 29.97 fps
Lower Field First
DV Video Encoder -- type 1
DV Audio -- NTSC, 32.000 kHz, 12 Bit, Stereo

Hi
Yes there is a way to allow VS to create a video file large enough to fill the disc, whether this will improve quality is a matter of trying.

The properties you give appear to be the capture properties of your video.(AVI)

Before burning a dvd these files have to be converted to a standard Dvd (Mpeg 2) format.
The process called rendering is done immediately prior to burning by VS, from Share—Create Disc, or by yourself from Share—Create Video File, the latter being preferred.

A standard template for the Mpeg 2 file looks similar to this:-

MPEG files
24 Bits, 720 x 480, 29.97 fps
Upper Field First
(DVD-NTSC), 4:3
Video data rate: 8000 kbps
LPCM Audio, 48000 Hz, Stereo


The ‘Video Data Rate’ is the main controlling element over, memory size and quality.

At 8000 kbps your video will be dvd top quality, and will fit 60 minutes to a disc.
At 6000 kbps your video will be dvd very good quality, and will fit 90 minutes to a disc.
At 4000 kbps your video will be dvd Vhs quality, and will fit 120 minutes to a disc.

So you can see that by altering the bit rate you can alter the amount of video to each disc.
If you are allowing VS to render in the burner module then it may be using 6000 at a guess, hence the small file size.

You can use the Make Movie Manager to create your own templates.

To assist you in choosing the correct bit rate there are calculators, have a look at this one:-

You should be able to fit 120 minutes of good Vhs quality video on one disc.

Hope this Helps
