  • Tod, thank you for the info about Brightsign.

    For anyone who has a similar problem—trying to play your own edited 4K or HD MP4 videos through an A/V receiver for improved audio (vs. playing through a TV), I ended up purchasing the Dune-HD Magic 4K Plus. I’m very happy with this unit.

    I connected the Dune-HD via HDMI out to the Marantz ‘media player’ HDMI in. The Dune Magic 4K instantly finds and plays the attached USB SSD drive. 4K playback is … 4K playback, and the audio through the Marantz is obviously better than connecting through the TV.

    I did have one issue initially: when playing a video there was a 2-second video and audio blackout about 1-second into the video. Dune suggested resetting the video mode from ‘Auto’ to 4K 2160p 29Hz in setup. That change solved the initial black-screen blink. Videos now play immediately.

    The Magic 4K Plus was less than $140 on Amazon.

  • Tim: To ensure you’re not overlooking the obvious: make sure DaVinci is using your graphics card as the primary processor (not your cpu). This can be configured in settings.

  • Hi Riccardo. Ideally, yes, I was looking for an XBOX app that would play 4K MP4 videos connected via an SSD USB. However, there are no apps that play 4K video (I have tried them all).

    I am therefore researching hardware devices that will allow me to connect an SSD into my Marantz AV receiver via HDMI. (None of the Marantz units will directly play video.) Don’t need to stream anything from the media player; only need to access my personal MP4 videos.

    Have decided to try this:

    On the VHS side, several years ago I transferred decades of 8mm video cassettes to digital files. That was a head-scratcher to figure out how to capture all that old technology. Fortunately, I several old 8mm video cameras—but one of them had an obsolete firewire output. I ended up purchasing a FireWire card for my PC from Amazon. I had an old FireWire cable. The problem was finding a current driver, because the last time Windows included a FireWire driver was Windows 7. Eventually I found a FireWire driver on the net:

    It was another challenge to find software that would drive the Sony camera for capture. These are the combinations that worked for me:

    Older Sony 8mm video cameras: RGB out > Roxio RGB to USB adapter > Cyberlink software.

    Sony 8mm video cameras with iLink: iLink out > FireWare card (see above) > Sony Vegas 14.

    For what it’s worth.

    OK, yes you did indicate a Mac. So much for my speed reading class. Have you tried decreasing the timeline playback resolution?

    Edit Tab > Playback > Timeline Proxy Resolution > (Try “Half” or “Quarter”). This only affects timeline playback resolution, nothing else.

    Also, are you using a graphics card, and have you updated your driver recently?

    If you’re using a graphics card, have you pointed Davinci Resolve to the card as your primary GPU in Preferences? From the menu system:

    > DaVinci Resolve > Preferences > System (at the top of the pop-up window) > Memory and GPU > Then point to your graphics card in the ‘GPU Configuration.’

    When you’re in the color tab:

    1. Select the clip that you want to copy the colors to.

    2. Right-click on the clip from which you want to apply the colors, and click ‘Apply Grade.’

    OR, check out “Power Grade” in various YouTube videos.

  • Hi Kenneth. I logged into Creative Cow today, read your question, and empathize. I don’t have a clear answer, but I have a few ideas.

    The fact that you are seeing the video artifacts in both source and timeline viewers suggests a hardware problem—to me, anyway.

    The first flag for me is that you are attempting to view UHD (3840 x 2160) video, but your monitor is set to 2560 x 1440. You have a mismatch between what you’re attempting to play, and what your monitor is capable of delivering. My guess is, this might be what’s causing the bad video in Resolve—particularly because both the source and timeline viewers are scaled down (e.g. not full-screen).

    Your graphics card and monitors appear to be capable of supporting UHD. So, why is Windows recommending 2560 x 1440? Something’s amiss.

    Go into Windows settings and see if you can set the resolution to the higher 3840 x 2160. If Windows doesn’t give you an option higher than 2560 x 1440, Windows thinks you don’t have a UHD monitor attached. The question is why. If you can’t figure it out, call MSFT tech support to ask them.

    Before you do that:

    > Check to ensure your video cables are up to spec.

    > Open the GeForce Experience software to update the RTX 2070 driver to current version.

    > Update DR to the most current release version (mine is 17.4.6 build 4).

    > Update Windows to the most current version. Are you using Win 10 or Win 11? If Windows 10, then upgrade to Windows 11. If Windows indicates that your PC isn’t capable of the upgrade, that may be another clue that your motherboard isn’t fully capable of supporting UHD.

    (I’m sure you’ve done all the above, but just double-check those steps before you call MSFT.)

    Some ideas for you.

  • Michael—I purchased the pro version of the Voxengo resampling software (I like to support boutique developers), converted the audio clip from 44.1 / 16-bit to 48 / 24-bit—and I still had the same problem. At that point it should have worked, so I concluded that the DaVinci file was corrupted.

    I deleted the file, started from scratch, imported the re-sampled audio clip, and everything was fine. Not sure how the DVR file got corrupted, but that was the problem.

    Thank you for the intro to Voxengo. Does his plugins work with fairlight, or only with DAWs? Does his plugins work with Studio One?

    Thanks again,

    Jean, try doing a test render of that segment to determine if the red dot appears in the final rendered video. My guess is that you won’t see it in the test render.
