Hi all,

This is probably a silly question but I was wondering if it's better to create a DVD straight from the editing project, i.e. with all the video & audio tracks, titles, transitions etc in place or use an .avi file that I've already produced from the project. The DVD creation should a lot quicker if I use the prerendered .avi, esp as its a long project with lots of enhancements and a few effects used. Is there likely to be any loss of quality? I'm guessing there shouldn't be as the .avi file is much bigger than that used for DVDs.

Many thanks in advance.

If you are creating a standard DVD, you have good results if you produce to MPEG2 HQ if you have a lot of transitions.
The choice of MPEG2 is because, that is the format of the VOBs on the DVD.

If creating a AVCHD or BluRay produce to AVCHD.

By producing your project first, you relieve the computer of the double duty of rendering and creating a DVD at the same time.

Plus if you have a hangup in the timeline the production may catch it. Carl312: Windows 10 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1GB,240GB SSD,two 1TB HDs.

Thanks for the quick reply Carl.

I've already produced an .avi file for the project. should I re-render the entire project to MPEG2 or could I just put the rendered .avi file on the timeline then go to 'Create Disc'?

Do I risk some loss of quality if I use the rendered .avi file to create a disc?

I hope I'm making sense, I think I'm starting to confuse myself now ;

I'm guessing the rendered .avi file will need to be re-rendered to MPEG2 on-the-fly before being burned to disc.

I'll take your advice to produce an MPEG2 first. I'm now trying to figure whether to use the original project (with clips, transitions etc. or will he rendered .avi production suffice (without losing quality).

Thanks again.

Anytime you re-compress video you lose some quality,

I doubt you would lose much if you rendered the AVI to a MPEG2 as long as you use the HQ profile.

When burning a DVD, PD would not have to render, it would basically copy the MPEG2 to a VOB format.

Pd probably would have no problem using a AVI, but it would be rendered on the fly to VOB files on the Disk. Carl312: Windows 10 64-bit 8 GB RAM,AMD Phenom II X4 965 3.4 GHz,ATI Radeon HD 5770 1GB,240GB SSD,two 1TB HDs.
