Sill Image Size in VS

[Ken Veal]

VS 11+
PAL
4.3
In http://phpbb.ulead.com.tw/EN/viewtopic. ... 526#119526
it is advised to use a still image size of 768x576 ( which is the width?),
I am getting the top of some photos taken with a still camera chopped off.
If this suggestion is used will this solve the problem that shows in my DVD .What I dont understand that this image size seems to be more that PAL size is in the first place.
Also, how do I change the still image size in VS 11+, cant see anywhere
in Preferences or willI have to do that in Paint Shop X when I edit them before use in VS. ....................Ken

Hi Ken,

When you add the still in the video track it should automatically fit the entire still in the frame....just make sure the top isn't chopped off in the original.

Moving the still in an overlay track gives you more options of manipulation with the still, when you right click on it while it's on the preview pane you have options to keep aspect ratio, fit to frame etc etc

The still can be any size you like really but when you have less pixels to work with you have to be aware that you are limited with how far you can zoom before you start getting distortions

Hi Ken

We know that normal video is 4:3¡K¡K..
A Pal video uses 720 x 576 as its frame size, this is not 4:3 the video clip is stretched to fit the 4:3 frame. You can look on the pixels as being rectangular not square.

When we use still images the pixels are square.

If you wish to fill the video frame with a still image then use a 4:3 aspect image, any size should do providing its 4:3 ratio.
For Pal video this relates to 768 x 576. and this should be the minimum size used.

If you are intending to use Pan and Zoom then you should use larger images to allow for the zoom effect. The 768 being the horizontal measurement.

OK

You Say (If this suggestion is used will this solve the problem that shows in my DVD)
This is probably an overscan problem.

Safe Area aka Overscan.

When we view our video on a normal TV, part of the picture is lost around the edges of the screen, its as though the video is wrapped around the sides of the screen.
The effect is not usually apparent with motion, but start to view your still photographs and it can be very annoying
(If you view the video on your PC you should see the full frame¡K.. No Overscan)

Imagine losing 10% to 15% around the image edge. Because that¡¦s the amount of overscan you can expect. So an image will loose detail around the edges, if its been taken as a close-up then the lost area may contain important details. A lost scalp doesn¡¦t look good.

There are ways to avoid the effect, but its probably a matter of knowing the limits.

Ken¡K.Do you think overscan is the problem????????

Hi Trevor,
thanks for the detailed explanation.The photos in question were close ups that had to be taken at very short notice.As you said scalped images of people are not too clever.Perhaps because of this and the fact you would not notice a scalped blue sky overscan could be the problem.
What I must do in future is to not get people anywhere near the top of the photo in the first place! ........................Ken

But, next time you see an interview on TV pay close attention. The interviewee's head is almost cropped.

Will look out for that Jeff and will also bear in mind that the cameramans
lens probably cost 10 more than my camera and he gets paid for what I try and do as a hobby- but he does not get the help of this forums members! ..........Ken
