4K Chat

    Tip

    A practical colour/focus check over a P2P call

    “I 4kChat because the client and I need to judge the real feed — not a compressed proxy.”

    Before anyone judges a take, spend two minutes proving the review window is honest. It saves arguments later.

    The two-minute check

    • Hold a white or grey card in the hero frame. Ask the client: does it look neutral, warm or cool?
    • Put a focus target (a printed chart, fine text, a fabric) at the subject's distance. Hold still for three seconds so the encoder settles.
    • Put a face in frame. Skin tone is what clients notice first.
    • Have the client pin the camera full-screen on their best display — not a phone, not a small window.

    Reading the result

    If the card looks neutral and fine text is readable, the feed is good enough to judge focus and framing. If detail is soft, check the sender's uplink first (wired beats Wi‑Fi), then whether the client is on a weak network. Resolution follows both ends; it is never guaranteed.

    Know the limit

    A browser call is a review window, not a calibrated grading monitor. The client's display, its brightness and its colour mode all affect what they see. Use the call to catch focus, framing and obvious colour drift. Leave final grade sign-off to a calibrated display and delivered files.

    Setup gear: the checklist.
