Excessive flickering: increasing pixels per line.
Posted by Riccardo Zito on August 25, 2005 at 10:35 amhello creative community..
Does anyone know how to create 3 pixel lines so to avoid excessive flickering. I am working a lot with still images and they flicker when I play out the movie and play it back as a dvd. I heard that by increasing the number of pixels per line (i.e. three rows of pixels per line) the image shold somewhat be stabilised.
Though I have no idea how to do that.. what should I look for in the settings?
Love.

August 25, 2005 at 12:01 pmThis advice only applies to actual “LINES”, such as a straight line created in a Photoshop document.
It is advice to image creators to not build-in lines that are too slender.However, it does not mean you can do this to existing images.
But, what you CAN do is add a bit of Gaussian Blur filter (adjust until the excessive “sharpness” is reduced) thereby effectively “widening the lines” somewhat.
BTW, you should always view your output, during the edit, on an external video monitor (not the computer screen). This will reveal these kinds of problems (and allow you to fix them) before you output. This is how FCP is designed.

August 25, 2005 at 12:28 pmThanks Matte I will just go with the gausian blur then..
(and buy an external monitor).
What gausian blur is standard.. between 1 and 2.5 px.. ? is that fine ?
Thanks for your help.

The settings you suggested are about right, but it all depends on the source material.
Too much and the image appears blurry, not enough and the “shimmer” will still be there.
And, as much as a fraction of a number either way can make a big difference.
You can even key-frame the amount if you are “zooming” on an image (it will take MORE blur as you make the image smaller).
That’s why you NEED to SEE it as you adjust.You can use ANY TV monitor that you have already (until you buy a “good” one, if you choose).
Monitoring FCP on an external video monitor is as easy as:
Mac > Camcorder > Monitor.Here’s how to connect it, step-by-step:
1. “Quit” the Final Cut Pro program.
2. Connect your camcorder to the Mac via FireWire.
3. Hook any standard monitor or TV (with a video input) to the outputs on your DV camcorder.
You can use the standard (usually colored yellow) video cable or the “S-video” output from the camcorder if the monitor has one of those kind of inputs.You should ALSO hook up the AUDIO outputs from the camcorder to the same monitor, or any “amplified speakers” so you can monitor the FCP audio along with the video.
4. Turn ON the camcorder. Switch it to the VCR (player) mode, but don’t put a tape in it (unless you intend to record from FCP to a DV tape.)
5. Turn ON the Video Monitor and set to view the “Video Input”.
6. Open Final Cut Pro on the Mac.
7. In FCP, make sure under the pulldown menu: View > External > ALL FRAMES is set.
You should now see the output of FCP on the camcorder’s viewfinder screen AND the external monitor.
You will also hear FCP’s audio from the speakers that you connected to the camcorder (this is important for audio/video to run in sync).
