What dimensions etc should I use for still images in Videos ?
http://forum.corel.com/EN/viewtopic.php?p=93961#93961
PAL 4.3 is shown as 768 x 576
Is this the increased dimension for pan +zoom instead of 720 or what is the reason
for the higher number .......Ken

Hi Ken

As you zoom in to a picture you are viewing less and less pixels, eventually the quality will depreciate.
With larger images you will be able to zoom in with less quality loss.
Whether you can see the difference is another matter.

If you use 16:9 then 1024 x 576px will fill the frame.

I tend to double the frame size for my images.

Hi Ken
I think that 768 should be 720. To add to Trevors comments. If you take a normal image from a still camera you will find that you will need to reduce the height by a greater proportion than the width. This means that if you just resize the image to fit say 1024 x 576 as Trevor says then the image will be distorted. You need to use the crop tool set to 1024 x 576 px. This gives you better control of the overall composition. You will have to chop off much more of the height than the width. I tend to re-size the image to 1024px width maintaining the aspect ratio then crop to full width cutting a part of the bottom and top off to best keep the composition OK.

if you are doing 4.3 video then 768x576 is correct, it's quite easy to do the maths. If you use 720x576 there will be a slight extending of the still to fill the frame.

John said "You need to use the crop tool set to 1024 x 576 px." I cant see
any px measurement in the cropping filter am I missing something here or is this done somewhere else.
Also when "I tend to re-size the image to 1024px width maintaining the aspect ratio " was mentioned- do you mean 1024 H + 576 W or
1024x1024 or something else.

Hi Ken

To fill the video frame you need to use an image having the same shape as the video frame, now that make sense.
This is a 4:3 shape for normal video and a 16:9 shape for widescreen.

Your images should use these ratios to fill the screen.

The minimum for 4:3 is 768 x 576 (these are square pixels)
The minimum for widescreen is 1024 x 576. (these are square pixels)

The pal video frame size is 720 x 576 this is a bit confusing , but video uses a process called Non-Square pixel rendering,
this stretched the video pixels to fit the frame, whether it be normal or widescreen.

Ken---Just to Add,, when we talk about re-sizing our images, we are using an image editor not VS, then import the image with the correct size to VS

Thanks for that Trevor, that has cleared up the resizing issue

Hi Ken
You cant resize and crop still images for this purpose in VS. You need to resize and crop your still images in an external photo editor, then import the finished images into VS. Have you got a photo editor installed? Perhaps you had one with a printer or scanner. Let us know what you have then we can work from there.

I have Paint Shop Pro X

I have Paint Shop Pro X

Hi Ken
Don't use this one but have downloaded the trial version and will type up a step by step guide later this morning. Bear with me for a couple of hours.

Hi Ken

One thing that hasn¡¦t been asked is how big are your images.
Right click an image in the library or timeline and select properties.
The width and height in pixels please.

Maybe you can get away without re-sizing the images. For slide shows, it doesn¡¦t matter if the frame is not filled.

For special effects, P-in-P, cropping in overlay then yes you may need to adjust the original image.
A lot is really image/photo content, as to whether you need to adjust.

So how big are the images.

Try a FREE tool calld IFRANVIEW http://www.irfanview.com/

This is an excellent tool for resizing and a lot of other options.

As we are now getting differing views on the subject perhaps the Paint Shop Pro is not such a good idea after all! Haven't had a chance to install it yet anyway. Will hold up the step by step guide as it may not be necessary. I have to say though that in still photo editing to get the best out of a shot some cropping is usually necessary IMHO!

Got to agree with you there Ken, ( I mean John, ) most if not all of images i use with a video have had some external editing.

Hi Trevor. why do you use double frame sizes.? My experience is that it doesn't make any difference in resolution when e.g. zooming is applied.
