  • flicker on old footage

    Posted by Dan Crouch on March 26, 2013 at 9:45 am

    I have a flickering on some old footage that I can’t get rid of.
    It was Pathe footage, cut in fcp. I have slowed it down to 75 percent.

    Anoyingly the dvd authoring has started so I can only re export the video layer as sound has been done.

    Please can anyone help with this.

    What I see is some frame blending that looks very ugly.
    I guess introduced on the slow down and may be by a wrong managing of data bases.
    Try keeping the speed at 75%, but uncheck “Frame Blending” on the speed window.
    Which is the time-base of the archive footage, and which is the sequence time base?

    In some ways the age of the footage and its very interesting content forgives a certain amount of flickering and artefacts. Having said that It looks like a field issue or maybe some frame blending thats not helping. Does de-interlacing help at all?

    It looks like the shutter flicker from the old film footage. By slowing it down you are magnifying it.

    Thanks v much all for the post’s.
    I am busy until tonight so will check out the suggestions.

    Re the authoring, the sound is mixed and ready, but the video layer can be re done so need to get this sorted before we commence.

    It was slom-mo’d at 75 percent and de-interlaced.

    I did pull the original clip into Avid but the same thing happened. I can only think it was filmed at a really strange speed and the conversion is confusing it. I have a feeling it may need to be re tele-cinied (which would be a pain).

    Thanks again for post’s

    Most of these early film cameras ran at 18fps, so you’d have to start there with the telecine and adjust accordingly as you move it into digital editing, yes, a pain.

    it sort of looks like “lower field” footage that was dropped into an “upper field” timeline.

    As said, old footage was shot at 18fps. And the flicker is due to early cameras not having rock steady shutters, so exposure varied.

    The flicker is normal…it’s on pretty much all footage from that era. Let it go. We are used to seeing that by now…it’s not distracting. Well, unless you are in your 20’s and might have an issue with old footage…many young people don’t want to even watch black and white.

    I say live with it. Trying to fix it will be a frame by frame job that’ll last quite some time.
