Burning a DVD for a projector

[Norfolkman6]

I put together videos for a local cinema club (in the UK). The video is actually a slideshow saved as in Avi format, although I could put it into MP4.
The DVD projector at the club has a native resolution of 1280 x 800 (16:10) Is it possible to burn to this resolution? All the burners which I have are either 16:9 or 4:3. The DVDs needs to be autostart and continuous loop. What is the best way for me to achieve best possible fit for their screen? I don't mind black borders but don't want to lose part of the image. Should I use scaling or how should I go about this?

Software which I have available is:

Vegas movie studio
DVD Architect studio
Img Burn
Photostage Slidshow
Anvsoft any videoconverter
Freemake Video converter
DVD Flick

Photostage & Anvsoft give me the best results so far but don't always fit the screen well because of over/underscan.

I would be grateful if someone could tell me the correct way to achieve this.

Many thanks in advance

Nope. It's not possible to use 1280x800. DVD is max 720x576.

But a good converter should keep the correct aspect ratio with black borders. Maybe DVD Architect?

the correct way to do this is to squeeze the image to 4:3 and play back in dvd and select FULL or FULL2 (exact settings depends on model of projector) which will stretch image out to 16:10 ..

or burn it on a usb stick full resolution and play back off usb (a lot of projectors can do this - even loop)

What I'd do is:

1. Resize the 1280x800 image (a 16:10 or 1.6:1 DAR if using square PAR) to 634x576.
2. Pad (pillarbox) to 720x576 (or 704x576, depending).
3. Encode flagged as PAL SD DVD 16:9.

It will then show a 16:10 image (equivalent to 922x576 with square PAR) padded inside a 16:9 frame (1024x576 with square PAR). And it will automatically stretch it correctly on every standard 16:9 widescreen projector. On PC-focused projectors that use a 16:10 native resolution, it will depend on how it is doing the scaling. This varies with projectors (what is your brand/model#?). Could be it crops itself, could be it anamorphically stretches one dimension, could be it zooms in, etc.

I'm curious as to what you are doing WRT the framerate...

Very many thanks for the help, I'll give those a try.

Out of curiosity, I've just done the whole procedure beginning to end using Windows DVD Maker on an old Win7 machine and it has produced an almost perfect result !!

The video is a slideshow of still images of 3 second duration plus transitions, so I'm not sure that framerate is important. It is however 25 fps
