Re: Certain clips becomes pixelated and flickering in the timeline and in the export: BRANCED

I'm having a similar problem, though it is not consistent: pixilation of short sections when compiled in a new sequence. THIS ISSUE shows up in the Timeline playback (other casess reported where it only happens during media export). Variously:

>The pixilation will fix itself.

>Opening the source clip in the Source Monitor fixes it.

>Changing the duration of the clip fixes it.

Hi, rellimbor,

Sounds troubling. I wouldn't say I like unpredictable behavior like that. It would be helpful to get complete details of your system, especially your media. Was the video shot on a video camera or DSLR? Did it come from some other source? Let us know. If you could upload a sample clip and PM me the URL, that would help. I would try transcoding a sample clip to ProRes LT to see if the issue might be media related. Let us know of any results. 

 

Looking forward to hearing back.

 

Thanks,

Kevin

Hi Kevin. Thanks for responding.

>I shot this on iPhone Xr and iPhone 14. 

>After the first export, the iPhone 14 material had voice in sync with video, but the iPhone Xr material not.

>I ran it through Handbrake, which in the past has corrected audio/video sync problems (https://www.youtube.com/watch?v=eZHybKdyZ54), but it didn't work this time.

>The three strategies I described ending up fixing the problems: the audio sync'd in the Timeline and also in the export.

Consequently (and thankfully), I can't upload the problem to you. BUT: MANY THANKS.

Robert

    Kevin: Working on this test... 1. After I generate the source files with ProRes LT codec, the multicam sequence will refer to these without me having to regenerate a new multicam--RIGHT? 2. Will the audio tracks be improved by the ProRes LT codec enough that I need to regenerate an extracted audio track with Audition? (I'm thinking not.) Robert


    Howdy, there. 

    1) They should if they have the same name. 2) No, the previous audio should be fine. Let me know if it works out.

     

    Thanks,
    Kevin
