Rendering DV for burning to DVD optimum settings

[John Rofrano]

[Geoff Edwards] “What are the best settings for this workflow?”

You only have one option and that’s to render to MainConcept MPEG-2 using the DVD Architect template for PAL. Then render the audio as Dolby Digital AC-3 and use the same filename but with the .ac3 extension. DVD Architect will know this is the audio for the video.

If the quality isn’t goof enough, press the Customize button for the template and check the 2-Pass option. This will take approximately twice as long to render but makes the most use of the bitrate. If you need even more quality, increase the Average Bitrate but know that as you increase the bitrate, you increate the file size which means you can fit less video onto the DVD.

Hi John

Thanks. I have rendered the project again checking that I am using the same settings that you recommend. Results are still poor. Please see linked photo from my 32in TV.

The render is better but deteriorates with time into playback. Movement is subject to the worst distortion, otherwise is almost VHS quality. VBR was set to 2 pass and 8,000,000 max 4,000,000 min.

The 10 minute project takes an hour to render.

Those are interlace problems. What do you have your Deinterlace Method set to in your Project Properties?

I have not set Deinterlace its set to none.

[Geoff Edwards] “I have not set Deinterlace its set to none.”

Then you’ve correctly identified your problem. Your VHS video is interlaced. You must select a deinterlace method to deal with it. I recommend you use the default which is Blend Fields. This will get rid of that horrible comb effect.

Thanks John 🙂

since I copied the VHS and SVHS to DV I thought the footage wouldn’t be interlaced. Should I also deinterlace when I render to MP4?

[Geoff Edwards] “since I copied the VHS and SVHS to DV I thought the footage wouldn’t be interlaced.”

Every one of those formats (VHS, SVHS, & DV) are Interlaced formats. There is no reason to think that they wouldn’t be interlaced.

[Geoff Edwards] “Should I also deinterlace when I render to MP4?”

Yes, that is the proper time to deinterlace the footage. Keep it interlaced through the entire editing process and deinterlace it for delivery. If you also plan to create DVD’s those should remain interlaced.

I don’t seem to be able to highlight part of your post in order to quote.

Just one further question: “if you also plan to create DVD’s those should remain interlaced” I am confused now. To get rid of the distortions when creating the DVD for TV use I had to deinterlace the project.

[Geoff Edwards] ” “if you also plan to create DVD’s those should remain interlaced” I am confused now. To get rid of the distortions when creating the DVD for TV use I had to deinterlace the project.”

No, you did not deinterlace the project. You selected a deinterlace method to be used whenever the media needs to be deinterlaced. That has no bearing on the project. Your project interlacing is controlled by the Field Order setting. Hopefully you have this correctly set to Lower Field First for DV/VHS media. The deinterlace method tells Vegas Pro how to handle interlaced media if and when it needs to deinterlace it (like when you resize it or render it to MP4). It will have absolutely no effect when rendering to an interlaced media like DVD.

Thanks John

I find it very difficult to understand but I think I am making progress 🙂
