Straight answers about trials, licenses, privacy and compatibility.
No. All three are OpenFX video plug-ins built specifically for DaVinci Resolve's video editing and color page. They analyze and process video footage frame by frame - they are not general-purpose photo tools, and they are built for video editors, colorists and filmmakers.
Yes. The trial has every feature, lasts 7 days and has no watermark. We do not ask for a payment card, and nothing is charged automatically when it ends.
The plug-in stops applying its effect and shows a LASTFX watermark on your picture (your footage itself is never changed or deleted) until you activate a license. Your grade settings are not lost - the node just shows the watermark instead of the effect. The end date is decided by our server, so changing the computer's clock does not extend it.
No. Licenses are a one-time payment. The pricing page states the number of activations, the update policy and the support period before you buy.
A standard license allows 3 active devices. You can deactivate a device at any time from your dashboard (or from the plug-in) and activate another.
No. Rendering never contacts the server. The plug-in checks its signed license file locally and checks in with the server roughly once a day. If you are offline it keeps working for up to 14 days after the last successful check.
We never upload footage, reference frames, project files or DaVinci Resolve projects. Activation sends your license key, a salted one-way device identifier, the plug-in name and version. See the Privacy Policy for the full list.
No. It is a deterministic video frame-analysis algorithm (robust statistics in linear light). It is not machine learning and we do not describe it as such.
It matches measurable statistics and color: exposure, contrast, white balance, tint, saturation and tonal color balance. It is closest when the two shots show the same scene, even zoomed or reframed. With a reference from a different scene the shot takes on the reference's look (brightness, contrast, warmth, color richness) but does not become the same picture: a teal sky in the reference will not appear in a shot that has no sky. Treat it as a fast starting point that you can fine-tune, and lower Match Strength if the look is too strong.
Run Workspace > Scripts > LUMERIX Batch Match, click the reference shot, mark the target shots and press Match Selected Shots. Every selected shot is matched to the reference in one click. The script never copies or replaces grades: it attaches the match as a 3D LUT to one free node of each shot, so the nodes you already have stay exactly as they are, and Remove Match takes it off. It works on Rec.709 / sRGB timelines and needs an active trial or license.
We only list versions we have actually tested; the current list is on the Installation page. The plug-ins use the standard OpenFX interface and 32-bit float images.
Not yet. The current release is for Windows 10/11 x64. The code is organised so a macOS version can be added, but we do not offer one today.
LUMERIX and GRAINOVA do: on NVIDIA GPUs through CUDA when the host renders on the GPU, otherwise on the CPU using all cores. In our benchmarks on an RTX 5060 test PC the GPU path was about 70 to 90 times faster, and it matches the CPU picture in our automated tests. We also checked it inside DaVinci Resolve: a frame rendered with Processing Mode set to CUDA matched the CPU result. FILMCHECK analyses on the CPU and needs no GPU.
Yes. Set Input Encoding to match what the node receives (Linear, Rec.709 Gamma 2.4, sRGB, DaVinci Intermediate, or a camera log: ARRI LogC3, Sony S-Log3, Canon C-Log3, Panasonic V-Log, RED Log3G10). Only the curve is converted, not the colour gamut. For HDR timelines set Highlight Protection and Highlight Compression to 0, because values above 1.0 are valid there.
Open the LICENSE section: it shows the status. Without an active trial or license the plug-in passes your footage through. Start a trial in your account, paste the key and press Activate.
Restart DaVinci Resolve after installing, then open Effects Library > OpenFX and search for LUMERIX, GRAINOVA or FILMCHECK. If it is missing, run the installer again and check that the OpenFX directory was detected.
You can ask for a refund within 2 hours after your payment. After that there is no refund. See the Refund Policy, and contact support with your order number before the 2 hours are over.
