TV PC Card Capture

[andyjamieson1]

I'm trying to burn captured tv pictures to dvd. the captured video is mpeg 2 PAL 544x576 upper field first max bit rate 15000.

What settings should I use for the project to maintain the original quality?

It is the 544x576 that's throwing me as there is no equivalent setting available in VS9, also what bit rate should I use?

I have done a search and could find nothing that helps.

Thanks for any suggestions in advance.

Hi Andy

As you say the frame size is incorrect, where did you get that from?
The bit rate of 15000 does not make sense either.
How and where did you capture the TV footage?

Using VS 9

For Pal the frame size should be 720 x 576
The bit rate should be 8000 kbps max this will give you about 60 minutes to a disc
Using 6000 kbps will give you about 90 minutes per disc
And 4000 kbps will give you 120 minutes per disc.

From capture, selecting DVD as the format will use the default template as :-

MPEG Files
24 Bits, 720 x 576, 25.00 fps
Lower Field First
(DVD-PAL), 4:3
Video data rate: Variable (Max. 8000 kbps)
LPCM Audio, 48.0 KHz, Stereo

As you are capturing from an analogue source the field order is most likely ‘upper field’
The bit rate can be altered to reflect the duration (such as 6000 for 90 minutes)
I would use constant bit rate (that is a personal choice)
And the audio use Digital Dolby

My capture settings would be:-

MPEG Files
24 Bits, 720 x 576, 25.00 fps
Upper Field First
(DVD-PAL), 4:3
Video data rate: 6000 kbps
Audio data rate: 256 kbps
Dolby Digital Audio, 48.0 KHz, Stereo

Selecting ‘Options’ then ‘Video and Audio capture prop…..’ capture tab--Advanced
Will allow you to select the capture properties.

Hope this helps.

Are you capturing Digital Video Broadcast? Somewhere, I read that DVB streams have headers (or something like that) that "claim" 15,000 kbs, but that it's not true. The quality should be quite good reduced to 8,000 kbs or so (which is within the DVD limits of about 10,000 kbs for combined video, audio, subtitles, etc.)

I'm not sure about the 544x576 resolution... Does your capture device have any alternative settings? Does it get streached-out when you open it in Video Studio?

Thanks guys for the replies.

Some clarifications

I am using video files captured directly by / from my digital tv pc card (Twinhan DTV PCI- Terestrial). The card only appears to be able to capture at the settings that any particular channel is broadcast at. In this case 544x576 VBR max 15000. (I got this info by importing the captured video into VS9 and checking the video prefrences).

Once opened in VS9 it does not appear stretched but looks like normal 4:3?

Hi Andy

As Dvddoug said you will have to reduce the bit rate to 8000 by rendering the captured video to a DVD compliant file.
I do not know how long the process will take, it could be a long time, changing the frame size may prove difficult, try a short 5 minute clip as a test.

If the video is longer than 60 minutes you will have to reduce the bit rate to reduce the file size to fit to disc.
To render.
Go to Share—Create Video File—

Select ‘Custom’—Options
Compression tab—‘Media Type’ Pal Dvd
Now use these settings

MPEG files
24 Bits, 720 x 576, 25 fps
Lower Field First
(DVD-PAL), 4:3
Video data rate: 8000 kbps
Audio data rate: 256 kbps
Dolby Digital Audio, 48 KHz, 2/0(L,R)

Others on this forum may have experience with digital tv.

Hope this Helps
