Blur edge

Well if there is a filter sharp edge I need the oposite one, does it exists? I am editing video and I resolved the problem (as you know you can not just put, the for example, jpeg in the timeline and on the tv screen get a good pic without the optimatization) by resizing the pic under the pal resolution and bringing back to the 768x576 (or NTSC resolution if you are in US) and it's perfect. I am doing it using batch automating options so it does not take time but however I was in a big trouble earlier trying to fix this problem using a Photoshop 7.0.
If somebody have that filter I will apriciate if you can send it to my mail or explain me how to make batch (automate) process to blur only the edges of the pic details so the photo still will be clear. I have a thousands of pics to optimatizate.

Thanks

It is interesting that 1 year ago I posted the same question in a few news groups and I did not
receive any suggestion, answer... whatever. I have a couple of Photoshop books from that one
for dammies over the photoshop bible through the one for the experts and nowhere is saying about optimatization
pics for video. I don't know is something different now with the photoshop CS but if it is could somebody inform me
about it. I know that my problem can be resolved by bluring the edges (I did it but I can not use the same
settings for more pic and one by one is impossible, takes alot of time). The filter should exist, I am sure...
HELP!!!

I gather you want to get rid of the line jitter associated with an interleaved video image. Photoshop 7 is fine for this, and in fact This can be done nicely using Photoshop's "Image Size" command as follows:

Uncheck the "Constrain Proportions" box, and resize the image to a height of 288 (1/2 of the height of the screen), and leave the width the same. Then resize back to the original height. This effectively blurs in the vertical direction only, getting rid of the jitter, retaining the full horizontal sharpness. You may find that resizing to a larger number (2/3 or 3/4 of the height) works well too.

Make this into an action as you did before, and you can apply it to any number of images using Phtooshop's batch capability.

As a further refinement, you may find that sharpening your image before the resize gives an image with more detail, and don't neglect to convert your image to the NTSC profile.

For certain images, for example a title image that people will see more than once or for an extended period, you may want to spend extra time masking only the areas that have sharp horizontal edges with objectionable jitter, and retain full detail in the rest of the image. To do this, duplicate the original image, run the vertical blur operation on the copy, and then paint a layer mask that is white only for the jittery edges. This operation could be made into an action as well, but it is more involved and the quality increase is small.

Mike I really apriciate this answer. I started my own business, digital studio 2 years ago,
and in the begeining I did not think about that stuff 'cause I was using 100 Hz TV displays and
on them everything looks perfectly fine. Then I was bluring all pics with a blur filter, later
selecting shadows, middle tones..etc... bluring just that selection and I wasn't satisfied, all my
professional equipment was giving me terrible final product thanks to my knowledge, everything was fine but
pics on normal TV dispaly were not fixed, they were shaking... Then I (after many many hours) found out if I risize my pic and get back to PAL (I'm in Europe) size
that it's much better. I was doing it untill now like that. I'll do like you suggest, it gives me even more
better (I was not using sharp filters 'cause I was sure that it will distort the pic again).

Thanks alot ;)
That was a really usefull help
