    Reducing Flicker from movies to DVD

    My search did not come up with posts about this particular issue, although it must be a fairly common problem.

    I'm transferring another friend's older VHS tapes to DVD.  Word gets around when you can do this. Doing it for free because they are good friends.  Doing some old movies (perhaps 8mm?) on VHS tape, capturing them into my computer by Dazzle - works so great!  Editing was pretty simple, and I burned a test copy on RW disc.  Disappointed to see distracting flicker throughout the whole 17-min. movie when viewed on the TV.  As I recall, that has to do with the different fps rates of movie film and video/TV.  I looked for the Reduce Flicker selection and could not find it.  I'm pretty sure I have used that successfully in the past with this problem.  What do you suggest?

    I have ST16, but gave up on it for this project when I could not figure out how to do a simple gradient title. I tried all sorts of ways to get each corner of the title the color I wanted, but could not get it to stay with the choices I made.  Worked with putting color in the 2 little boxes in Background, but the colors kept disappearing.  It must be simple, but I continue to gripe about how much more intuitive ST14 is for a fairly simple project like mine.  I loaded Corel, I think, as one moderator suggested, but have not taken the time to work with it - keep forgetting I have it, and just go to ST14 which usually works best.  Scared to death to try ST10, or whatever the latest version is  Confused

    Okay, back to my Reduce Flicker question.  I'm assuming Stabilization is a different animal, not meant for reducing flicker.  What do you suggest?

    Thanks.

    Flickering = unexpected variations of luminosity.

    Is that what you're talking about Margaret ?

    I guess - I'm not real up on the finer points of luminosity.  It's a regular and repeated flickering of the movie in each scene, all the way through the video.  It's not unexpected after you see it happen in the first minute, and it continues.  Like regular flashing of light, perhaps, like you would see in old silent movies.  Does that describe what you were thinking of? 

    I think I learned in my Basic Video Production class 10+ years ago that it's because film is 28 fps and video is 30 fps, something like that.  In fact, I bought a used variable speed projector to take care of that situation when transferring my own movies to video.  That was several years ago when I was gung ho to put our home movies onto DVD, but I have never used the projector and never completed that project.  It's on my list, though.

    In fact it's a matter of shutter speed, not framerate.

    Read this article.

    Now, that flickering is in your video, there is nothing you can do in PS14 to solve it. You need more powerful tools, like Avisynth scripting but tha'ts another story. Deflicker or Reduceflicker filters are good examples of tools that can be used.

    Oh, yes, I remember now that it was a little more complicated - getting a multiple of 20 or 30, or something like that.  The article and video was informative, but I guess does not help me at this point.  I just looked at the VHS tape again, and it flickers just like the DVD.  Guess I assumed I could correct that in editing, and didn't think too much about it until seeing it when all done.

    Leafing through old ST manuals just now - would reducing the speed of the finished ST video help?  There is no sound to the movie.  Or does the speed change have to come earlier to do any good?  I'm burning another video now so can't experiment.

    Tweaking speed now is useless, it's too late. Damages are now recorded in the video.

    Just to clarify - since the flicker was already in the VHS video, nothing with Dazzle or any other transfer method of VHS tape would have made any difference, right?  So copy as is, flicker and all, and not concern myself about it any more?  

    Thanks,

    Yes.
