.mpg/.avi to Screensaver (.scr)?

[therock003]

Is there any quick and easy way to convert files to screensaver format without re-encoding if possible? I have a video pattern that simulates the television static signal, and i want to make it into a screensaver, in order to prevent the burn-in effect of my plasma.

A screensaver is a PROGRAM APPLICATION. Basically, a special player app (that has to be built to follow certain APIs). There are some video-screensaver apps that allow for you to choose which video you want to display, but they probably built to only support certain formats, so you'd have to find out which ones first and then re-encode to that format. Or you could of course build your own...

Why don't you just have the screen go black?

I dont think its the same as running the pattern. A black screen will just help by not creating additional artifacts, but i dont think it will de-block the ones created, like logos, borders on non Fullscreen videos etc.

Another think i thought of since i'm using a remote (that i can program to send specific keystrokes) would be to create a shortcut with a key combination that launches the .mpg file. So lets say i set it to ctrl+alt+p, and that mpc-hc uses space to pause the video. I can program the remote pause button to send a space+ctrl+alt+p, so when i hit pause, it will pause my existing file, and launch the video file pattern into a new player window.

What do you think? Although that means that every time i pause even for trivial reason i will have that happening..

You're right screensavers arent eactly videos, just shapes that are generated, like computer graphics, but this pattern is somewhat like computer graphics as well i reckon. I'm not sure how this operates but i would think that pixel just interchange from black to grey for each frame.

So if you have a 4x4 frame, 1st frame should be b,g,b,g 2nd g,b,g,b. Is this how it works? Cause if it is it could be generated into a screensaver right?

So your not trying to "prevent" burn in, your trying to "remove" it.

No way, this one is much better:

Actually windows supports this builtin but supposedly you need wma for this to work. So any way i can transfer to a different container without reencoding

It's just static. Quality doesn't matter.

[therock003]

I cant seem to find this video i had of the static. Is there any way to create my own video with static noise?

WOW did you get lost in translation.

Why don't you just download the youtube video you linked to?

Here's a clip that I recorded many years ago, no sound, Xvid AVI. You might want to remove the bottom few scan lines because they don't change much. Crop and adjust the aspect ratio to suit your needs.

Yes, use Avisynth plus AddGrain() or ffdshow's raw video filter.

[therock003]

Thanx for that. Also can i turn this into a fullscreen executable that runs until i tell it to stop? Cause running it with my default media player, i will have to press key for fullscreen, and enable repeat file, both of which i have disabled by default on MPC.

If i turn this into a shortcut, are there commands i can add there to launch in fullscreen and repeat from there?

[jagabo]

If you go the AviSynth route, something like:

# create a 24 hour grey video
BlankClip(width=1280, height=720, pixel_type="YV12", length=2592000, fps=30, color=$808080)

# add noise, set uvar to 0 if you want only greyscale noise
AddGrain(var=10000.0, uvar=10000.0)

You can get a list of command line options for MPC: Help -> Command Line Switches.

The attached pair of files will play 24 hours of static. You will have to change the path to MPC. And you may need to specify the full path to the Static.AVS file.
