Thanks, now I'll show some ignorance.

Not clear on the "greater than your output" comment relative to P&C and the screen sizes I might show them on.

Also, based on what you said, if I do some zooming in via P&C, am I better to start with a 20" pic at 100 PPI vs the 10" at 200 PPI.

Any comments on the rendering setting? I'm using my Pany ZS3 with the AVCHD Lite so not a Pro model since only for friends and family.

Again, sorry if this is stupid, but it is a big help to me.

When dealing with resolution in TV, forget about inches and PPI. A Standard Definition TV image is 720 x 480 NTSC. You want your images to be at least 720 x 480. If you plan on doing zooms or moves, then you might want twice that resolution.

You say this is your first try at an HD format, but a DVD is Standard Definition, not HD. The only way you can view HD is if you burn a Blu Ray disc or play from an HD file.

The term "dpi" does have some meaning for video. The standard definition video system seems generally to be considered to be 72dpi. This makes some sense, at normal viewing angle a TV screen will look the same as a print of that size at 72dpi.

Of course unlike a print the video system has a fixed resolution so apart from the above the term "dpi" is meaningless.


The 2K x 2K limit applies only to project settings. There's no hard coded limit on how big a still image can be. Too many too big could run you into problems with having enough RAM. I've used jpeg, tiff, png, bmp without any issue, I've had tiffs of monsterous dimensions on the T/L and rendered out without issue and on a system with only 512K of RAM. Not something I'd want to do again though.

There's little to nothing to be gained going overboard with still resolution. It all has to get buffered into RAM and the higher the res the slower things can get. One tip I learned from a pro is to never have a still image absolutely static. Use the tiniest pan or zoom, the viewer doesn't have to notice the image isn't static for it to make a difference to the look of the image.

Bob.

The 72 DPI started because early monitors were actually 72dpi. But it has no meaning at all in video.

Humm... good point on the HD & Blue Ray.

I guess I'm really looking to use 'Widescreen' for the project settings and crop the pics so not to look squatty--as the videos are already in widescreen format. Does that sound right?

Follow-up on the pics please---are we saying these two would show up the same on a 65" or 120" screen from the DVD:

* pic cropped to 8 x 4.404 at 225 px to be 1800x991
* pic cropped to 18 x 9.909 at 100 px to be 1800x991

I know for printing, the 225 px is better for blow-ups, just struggling with the video impact.

Thanks again.

Something you might want to check out is Photodex Proshow Producer - it's purpose in life is making slide shows and has a LOT of options/power on what you can do with the slideshow. One of the output options is uncompressed avi (which I often use) which can then be brought into Vegas, add additional stuff etc then render to DVD or whatever you want. The two applications work well together ( I use both - trying to avoid the "when all you have is a hammer, the world looks like a nail" routine). Check out the Photodex stuff at http://www.photodex.com -- slide shows are much easier to create in an application designed for that.

There is none!

Pixels per inch do not show up on a TV, only pixels.
The input to a TV is the same, for instance 720x480, whether the TV is 20" or 200"
That is exacly 345,600 pixels inputted to either screen.

Once again, pixels are pixels. As someone else suggested, stop thinking in terms of inches and ppi, and start thinking in terms of pixels. With all due respect, you are overthinking. A TV is not a printer.

You have now been given the correct answer five times.
Re your first post, a DVD is not HD, it is SD. A DVD is not WMV, it is MPEG-2.
Converting your JPEG images to PNG will give you better memory handling in Vegas 8.0c

e we saying these two would show up the same on a 65" or 120" screen from the DVD:

I'm always disappointed when I see my projects on a 10' x 12' projection screen as I'm used to seeing them on a high res 15" CRT :-)
The bigger the screen, the more clarity you'll lose.
Of course, this assumes you're talking similar models and not a moped vs. a Harley.
I generally keep my stills at 2X project resolution.
That is, 1440 x 960 for NTSC DV.
Adjust these numbers according to your specific project settings.
In video, pixels are the only thing that matters, not the dpi.
