  Enabling video field processing causes aliasing in downscaled clips

  Posted by Joe Bender on July 21, 2018 at 1:12 am

  Hi all,
  Getting ready to conform/color a new project in Resolve, which includes a lot of downscaled 4K footage to a 1080p timeline and a few interlaced archival clips. So in order to correctly deinterlace the archival clips, I turned on video field processing. That works correctly for the interlaced archive, but it also creates serious aliasing in the downsampled 4K clips. This is not just a display artifact, it is present in the rendered footage. Now, I can handle the interlaced archive in a separate project, but for simplicity’s sake I’d like to do the whole film in one project if possible. Is this something that you’ve encountered, and is there a workaround?

  I am using:
  Resolve 15b6
  iMac 5k 4.2gHz 40GB RAM
  RX 580 8GB
  eGPU RX580 8GB
  macOS 10.13.6

  Many thanks,

  Joe

  You turned on video field processing on project setting? For progressive output this setting must turned off.

  Hi Massimo, thanks for your reply.
  I enabled video field processing because as far as I could tell that was the only way to get Resolve to deinterlace the archival footage correctly. Is there another method that I should use instead? If there’s something else I missed there please enlighten me.

  Thanks again,

  Joe

  deinterlace is a clip setting, leave video field processing off and tick “enable deinterlace” on clip attributes for interlaced footage ,
  this function is only available in Davinci Resolve Studio.

  Yes, that’s the nominal workflow, but when following that Resolve Studio was not deinterlacing my clips, just making them ‘wavy’, misinterpreting the fields or something. Resolve only correctly deinterlaced the clips when I turned video field processing on. I’ll try again to verify, but that’s the behavior I was experiencing.

  remember that you are using a beta software, have you tried with DR 14?
