3 problems with lcd, widescreen and audio

[Peter Wright]

1. To answer this, more info please. What settings do you use when capturing/rendering.
The other thing is that the quality of the finished DVD is also dependent on the quality of the footage. Vegas is extremely capable of producing good looking MPEG2 files.

2. You can make it into a widescreen project, and use Pan Crop to match the aspect ratio. This will effectively cut off the top and bottom of your 4:3 frame, and the pic will have to be slightly scaled up to a full 16:9 frame, which will cause some amount of degradation.

3.If you are squeezed for space on the DVD then AC3 will be the best choice. For shorter projects PCM is slightly better quality. 5.1 surround is a whole new ball game and you need to design the audio specifically with this in mind. So none is the best – they are choices depending on your requirements.

Here are the settings –
Template – Pal DV [720 x 576, 25 fps]
Field order – Lower first
Rendering quality – Good
Motion blur type – Gausian
De interlace method – Blend field

Rendering MPEG 2 settings
Video rendering quailty – good
720 x 576 – 25 fps
Display 4:3
I- Frame 12 B.frame 2
Profile – main
Field order – Interlace, bottom field first. Level- main level first
Video quality – High (?? I think I have a default setting on this one)
Variable Bit Rate –
Max- 8 000 000
Average – 4000 000
Minimum – 192.000

I havn`t been changing much in the capture mode… I live in europe so I had to change to pal-settings, but nothing else..

The problems appears when it`s some kind of motion in the picture.. It`s also some problems on some transitions… But the stills in my project works perfect.

Mm – doesn’t sound like you’re doing too much out of the4 ordinary.

You say “had to change to PAL” – was the original footage shot in PAL?

Yeah, my footage is shot in PAL.

Should I try to Change the video rendering quality to best, and the bitrate minimum to a higher level. It`s 192 000 now. It seems pretty low.

I just have to use some time and try to figure this out.

For the 4:3 to 16:9 convertion:

Should I render my movie (wich is in 4:3 for the moment) to a new avi track and then use pan/crop tool for widescreen? And then scale it? I`m a newbie on these kind of stuff.

Sounds like you’re getting compression artifacting if problems are showing up in fast motion or transitions. Up your minimum bitrate to 4,000,000 and your average to around 6,000,000 that should help a lot. You might also try rendering in progressive, though this is a prefrence based on your TV and where you want to show the DVD.

If your video is less than an hour long, use (bit rate) CBR of between 7,000,000 and 8,000,000. Some DVD set-top players have play back problems with high BR. AC3 5.1 audio takes less disk space than PCM audio.

To show 16:9, it’s best to shoot in 16:9, stay close to your subject, have lots of light, and keep focused.

I`ve tried to set myy minimum bitrate to 4000 000, the avreage to 6000 000 and the maximum to 8000 000,but I still have problems… When I`m showing the mpeg 2 in windows media player or real player there are problems with moving text… I have some text flying etc, and you can see it`s poor quality…. See lines in it… It`s the same with people moving in the picture…

When I`m showing the movie on a lcd tv it`s ok, but people moving is still pretty poor quality..(the text is good) I`m doing something wrong here, but I really can`t figure out what… Someone said something about rendering progressiv.. How do I do that…

I try this with a 16 minutes project, and the file is like `
744 000 kb. The first file I made with the default bitrates was about 500 000… So the file are bigger and better.. But still not perfect.. When I`m showing the rendered avi file on the tv (print to tape rendering) it`s perfect.. But I want it on dvd, and not dv-tapes.. Please help.
