OK . ..

"What is the best way to render a project to burn to DVD?

1/- As far as I know DVDs are only made using MPEGs

2/- AVIs, compared to MPEGs, are huge, HUGE!

3/- There are good converters getting AVI to MPEG .. .I believe DVDA and Vegas has some of the best.

4/- The MPEG conversion process makes fine products !

5/- Render/conversion times are things we all have to live with . .. sorry!

6/- I can go two routes:

Route No.1 > Convert within Vegas

Route No.2 > Convert within DVDA2

However, prior to going near the conversion I create a fully rendered DV-AVI. The value of this is that I will have:

1/- A backup file of the pre DVD encoding [ sorry, conversion is called "Encoding" ]

2/- You make a mistake - least of which, for me anyways, is spilling - you got a very quick fallback with the DV-AVI to re-edit and then re-encode.

3/- Saving rendering time. Having a completed DV-AVI, with all the complex maths that go on with complex projects, you've got all this done first - yeah?

So much for you to get hold of. But once you've burnt your first DVDs you'll take to it very fast . .. you will have forgotten this post . .. and you'll be reading posts here and thinking, "Ah, yes, it can be confusing" . . .

Best regards,

Grazie
