Delivery format for DVD?

Quick (and super newb) question here.

I'm an audio guy, know Fairlight reasonably well and simple video editing basics in Resolve. I did buy the Speed Editor when it was announced, so that makes me a professional, right? :lol:

A charity I work with asked if I could help clean up & edit some Zoom meeting videos that are aimed at people in US prisons and need to be laid back to disc (DVD sounded the most likely) rather than some other delivery format.

Zoom creates mp4 files with H.264 @ 25fps & AAC 32kHz mono audio, which I've used in Resolve before. What would be an ideal/appropriate delivery setting for going to DVD?

I'm pretty sure I have a version of Toast Titanium lying around on one of my systems, so could put the material on a DVD-R for them, if I knew what to deliver from Resolve.

Can anyone give me a few suggestions?

(Feel free to tell me to read the manual, take the courses, just as I tell others, but I'm not asking how to learn to be an editor, just what to output that will fit on a DVD. ;) )

Many DVD players will play a range of modern video formats, but if you want to make a proper DVD you will need to use DVD authoring software to convert the files to the appropriate MPEG2 VOB files and menus etc.

There are free DVD authoring programs available, but I haven't made a DVD for over 20 years, so can't help with specifics

You can feed Toast with a proper ProRes file anytime on a Mac. But why did you use 25 fps, being located in the US?
European players would play 25fps fine, but not all bought in the US, while 24 fps progressive always works. I'd suggest slowing it down in Clip Attributes to 24. The timeline resolution should bei DVD standard. And good luck with audio sync, those recordings might be VFR.

Thank you both for the replies.

I didn't record them, it was the workshop organizers and whatever Zoom uses as it's standard settings. No idea why 25 fps instead of 24. I can use Clip Atributes as suggested and move to 24.

Yeah, the audio may be VFR, I'll have to see, if so I might convert it to standard Wav and then re-sync with the picture afterwards.

I do want a standard DVD that will work in a standard DVD player, which is all the prisons will have access to. If that means MPEG2 VOB files, so be it. What format/settings should I export/deliver from Resolve that will give decent results when transcoded to MPEG2?

I do indeed have Toast, found it this afternoon, it has presets to make simple menus and chapter marks, which seems fine for this specific use case.

Cheers,
Thor

VFR (variable frame rate) is related to video. In longer takes, you may have to re-sync by cutting or adding a few frames of audio.

Your export should be 720 × 480, flagged for either 4:3 or 16:9, depending on content. ProRes 422 HQ will be plenty regarding final quality, even ProRes 422 is enough. Toast should take care of the rest.

Note that if you change the framerate using the Clip Attributes then you will lose audio sync over time because the audio remains unchanged whilst the video track will be longer (due to the slower framerate).

Right, forgot to mention that. You'll need to slow down the audio too.

Of course. Audio is my specialty, all good there. It's the video side I needed help with.

Thanks again.
