Hopefully my question is clear enough.

Depends on the kind of plasma TV. If the TV is ‘Full HD’, you need a resolution of 1920 x 1080 pixels, so if you use that size, you will always be safe.

Hello,

I am using PS7 and a DVD Slideshow software program to create a photo album to be shown on a 16:9 ratio, 50", Plasma TV.

My question is: "When saving the photo to be used, is there a certain size and resolution I should use to maximize the viewing size?"

Hopefully my question is clear enough.

Thanks in advance.

Yes, it is Full High Definition. So, in effect are you saying that if the dimensions of the image file was 960 x 540 it would fill half the screen? Am I understanding you correctly?

Thanks

Most images should display fine (clear) on TV, so pick your choice

– Depending on the slideshow program, most of them will convert from still image to MPEG format and very few can give good quality at SVCD. So I would suggest to go for DVD resolution

– Very few (old programs) don’t convert to MPEG but display them as still images (with time delay and without transition) will display great at VCD – If you going to display it on wide-screen then sure you can set to 16:9 ratio, but if you may display it on regular old TV then you may want to set to (4:3 ratio?). Because

– 16:9 screen won’t display good on old TV screen

– Most if not all wide-screen TVs have option to switch to different Ratio Aspects when old TV doesn’t have.

Not necessarily. It could also fill the screen, depending on how the software was written. After all, a TV show that is not broadcasted in Full HD also does not show at half the size. But if it does fill the screen, the quality will be much lower than it can be if you use the full HDTV resolution.

You are correct! most programs have option to display whatever resolution to match the Ratio Aspect setting, so the still images don’t have to be any specific resolution. Except for digital photo grame then it may have to crop to the correct ratio aspect of whatever size the digital photo frame is.

Should the resolution within PS be set to 96 ppi?

As it’s not being printed, it doesn’t matter -=unless=- the DVD software might ‘map’ it to a specific ‘size’.

BFS! IF the DVD palyer can map it to ‘fit’ a 3:4 format, the it will be nicely viewable. It just won’t have the "HD" resolution.

Guess you haven’t viewed any HD discs through a good player onto a 3:4 ‘old’ TV. Here the -=player=- is the key, not the software.

When converting / saving the image file with dimensions of 1980 x 1080 @ 96 ppi, the file size is over 8Mbs. Being the file size using this method is this large, are there alternative methods for "very good to great" viewing? Or is the large file size just the way it is to have quality viewing on a TV?

Thanks again.

If you’re going to "Full HD" then you need the information! What does it matter anyway as the disc you’ll be burning to has some 25 GB of space? 8 MB is a tiny, tiny ‘drop in the bucket’!

If you’re burning a regular DVD, your image is going to be downsampled (at most) to 720×480 anyhow.

So? 8 MB is a small image. I routinely work with images that are hundreds of megabytes in size.

First of all, ppi is irrelevant. The images will always show at the same size, whatever the ppi setting. Secondly, that 8 MB is the size of an uncompressed image. If you can save the images as JPEG (or an MPEG slide show), they should be quite a bit smaller. And finally, 8 MB isn’t that large. Even on a CD you can still fit some 90 images, and on a DVD that would be more than 500 images.

You are correct on all counts. It seems like many people have been reading some dated info from one man opinion then passing around to others.

– You are so right that PPI doesn’t mean anything. Or yes I can have 1-PPI image has much better IQ (Image Quality) than 300-PPI image (and anyone can do this if they just pay a little attention to it)

– I have been creating presentation (slideshow using ProShow Gold) from still images, and many presentations have 800-1,000+ images (few was up to around 1200-1500+ images). And like I have mentioned in earlier message that the size will depend on the FPS (delaying) setting.

The presentation (MPEG) doesn’t care if the still image is 5K or 5M, or it will give both the same amount of bytes (size).
