picture quality on television

Post by surfer »

I have read many posts on this: quality of pictires with videostudio (in my case 10 plus).

Evry year i want to see the pictures of my family taken with a digital photo camera with resolution: 2048 * 1536 pixels on my widescreen television. And everytime i have seen misplaced faces because the television is streching out automatically.

The quesions i would very much like answers about:
- Is it best to resize the photo's to a widescreen format before loading into videostudio? or resize to 720*576 format? or resizing not before but in videostudio choose the projectsettings?
- In videostudio must i change the project settings to avi or mpeg and frame based or lff - uff. When i am ready with the project choose mpeg or avi and then load the avi or mpeg in the make disc and then choose project settings pal dvd, frame based or lff uff.

I don't understand it anymore...

What i would like very much is to see a full photo with best quality on the widescreen television made by videostudio 10.

Here's what I do:

Use your photo editing or drawing software to make a 16x9 solid-color background. Use whatever resolution you want... just make the ratio match your TV.

Paste your image on top of that background without distorting its proportions. Leave some background showing around all sides to allow for the TV's overscan. Save the image.
or resize to 720*576 format? or resizing not before but in videostudio choose the projectsettings?
No. Don't re-size it first. 720x576 is not a 16:9 ratio. (The pixels in your photo are square, but the pixels on your TV are rectangle.)
When i am ready with the project choose mpeg or avi and then load the avi or mpeg in the make disc and then choose project settings pal dvd, frame based or lff uff.
Just choose a PAL DVD template (which will be MPEG-2) and let Video Studio figure-out the details.

I found a document on the internet and this says:

Best resolution is 640 x 480 because the 16:9 television can do best with photo's with this resolution.

Is this so..

I had a similar problem in Media Studio's Video Editor. The solution was actually simple.

A wide screen video is still 720*576, but the TV stretches it to 16:9.

What I did: I modified the picture from the camera resolution (in my case 2048*1360) to 16:9 (2048*1152) and put that image in the movie (in other words: I cut off a small part of the sides). I turned off the option "keep aspect ratio". In the rendering process the image was shown stretched. When I put it on DVD, I selected the option 16:9 or wide screen and the result was a normal picture on TV without distortion.

When the video is played with Windows Media player, it looks like the images is still stretched, but with a "real" DVD player program it is OK.

picture resolution / project

Post by surfer »

Let me refrase the question because this issue is alot asked:

What is your opinion to get te best photo quality on a WIDEscreen television.

I have photo's from my digital camera, resolution: 2048 x 1536
When i want to make a slideshow for the best quality on the widescreen t.v. must i resize the photo's to for example: 1024 x 576? or another format?
must the project in videostudio 10 be a 16:9 project or just a 4:3 because the photo's are also 4:3?

Is there a program that you will suggest to eassaly convert/crop alot of photo's to a 16:9 format?

Since I have no experience with Videostudio, I can only give advice in general.

The resolution for wide screen remains 720*576, only some signals from the DVD player will tell the TV that it should be played in wide screen. The video will be stretched to the 16:9 format, so it is important to make the picture in that format.

In my opinion it is useless to change the original format to a lower resolution. It will cost quality, because it will be downgraded by a photo editor programm and again by Videostudio to 720*576.

The only thing that needs to be done is to crop the original image to a 16:9 format and maintain the horizontal resolution. Personally I use Faststone Photo Resizer because it has a batch function, but Photoimpact can do the same job. Don't maintain the aspect ratio (no idea if this is an option in Videostudio, but it should be). Always look at the result, because it can cut off parts you might want in the image. If nessecary do it manually.

If you want, PM me and I will explain it in Dutch (native speaker).

Obviously, if you put a 4:3 picture on a 16:9 screen, it's not going to fit the screen. That's why I suggested making a solid-color 16:9 "image", and pasting your photo on top of that.

If all of your photos are 4x3 and there is no widescreen video in the project, a 4x3 project is a better idea. You are going to get "black bars" on your TV in either case, and a 4x3 DVD will work better if it's ever viewed on a standard TV.

For photo editing I use Paint Shop Pro. I also have Microsoft Picture It (which I think is no longer available). I assume that Ulead PhotoImpact can do it too.
Best resolution is 640 x 480 because the 16:9 television can do best with photo's with this resolution.
That would make the photo fit a 4x3 screen. The proportions are correct, but VideoStudio would have to fill-in the "missing" pixels (interpolate) to get 720x576.
What is your opinion to get te best photo quality on a WIDEscreen television.
I really don't know. I would guess that its best to feed Video Studio a photo that has the "correct" resolution in one dimension... In that case, 1024x576 might be best. Video studio can keep all of the '576' rows, and throw away some of the '1024' columns to make the stretched 720 columns fit. It's better to throw away data than to add data, and you must do one or the other to change the shape of the pixels without distorting the shape of the picture.

All of that assumes that your photo editing software can do a better job of re-formatting the image. If that assumption is false, you will get the same results by letting Video Studio do everything. There's no getting around some deterioration, since you must reduce the pixel count and change the shape of the pixels.

I have tried a couple of tutorials. For instance:
http://phpbb.ulead.com.tw/EN/viewtopic.php?t=9556

But when i do this (original size) and then keep aspect ratio he image is far to great. (looks likes it is zoomed in very much) on the television.

Another article does almost the same as above link but only he is not using "original size" but "fit to screen". I have also tried this a couple of times but when i play it on a widescreen t.v. there are two black lines on the left and ride side. The poto's are looking good though but not the whole screen is filled. Maybe this is the intention?
When i leave the photo's at 4:3 (2048*1536) and play them on a widescreen the photo's also looks good but streched left and right.

I also tried to change the resolution before i load them into videostudio to 1024 * 576. When i don't use pan and zoom there is almost no difference with 2048*1536 (the original size).
