    I might be interested in this if it were a Final Cut Pro plug in at a reasonable price.

    Hi Runsongas,

    We are talking on video, not images. There are other softwares such as photoshop that handles image.

    Hi Manatee Diver,

    Unfortunately there are agreements set in place which prevent third parties applications involvement.

    I don't understand what this program would do which I could not archive in professional colour grading software in couple of minutes or less. I am used to grade moving images though so maybe it is the easier user interface / no need to learn anything that is the point of the product

    (yes I have the Resolve Studio and the Mini Panel for it, makes that kind of "visual enhancing colour correction" a one minute job when you're used to it even when only using the video scopes for monitoring, no need to even see the actual image at all. Using AI for this job makes it easy for the end user of course, no need to know what a 'rgb parade' aka rgb waveform is and how it can be used for grading)


    Edit: tested correcting the cyan tinted tortoise image with the Resolve panel to a similar looking result than in that "final result" sample image. Took about 50 seconds to do with using only the scopes for monitoring

    Hi Runsongas,

    You are taking the image from the post and convert via the Dive+ mobile app, which is not the correct method to compare. You will need to use the original video and convert via Dive+ mobile app and again with CVC to compare the two results. Please see below on the same underwater video, which was converted by CVC Dive+ mobile app.

    Original vs CVC

    Hi almostDIR,

    Perhaps you are an expert in handling the colour grading software. However, not many divers out there can handle the software. In addition, the natural water depth colour has to be manually adjust by yourself and not many divers can differentiate the colour depth difference. What we carry out in CVC, was to extract the data captured in the IC chip of the camera that was being stored in the external drive (e.g. SD Card), enhanced and bring out the natural colour from the pixel level. All these steps will then be automated using the AI to process, making it user-friendly.

    Yep it is true that most persons need more user friendly options and are ready to pay for them. I see them just as automatic single button colour balance tools which can be handy when making basic videos but are generally not usable when making anything more serious. Though most people who claim they know how to adjust colors have no idea or any interest in calibrating their monitor so all the colour adjustments go to waste. For them the single button auto balance would definitely be a better option :)

    by IC chip you mean exif type metadata the camera has stored along with the footage? that does not help much with the water tint removal because all the algae etc. also changes the colors and the camera does not have depth sensor. even if it would have that it would only work in clean clear water like in the ocean with great visibility. Shooting a color chart or even a grey card underwater before any depth and visibility change would help a lot but nobody does that except for when shooting cinema grade material...

    Learning to use basic colour grading tools is relatively easy, I would be happy if the divers would bother learning to do even the basic adjustments to their footage and to learn to edit even a little bit so that the videos would be easier to watch and more interesting. it only takes some very limited amount of time to learn, one can manage very well with the free version of Davinci Resolve on any scuba diving related video project they could possibly have so it is only about bothering to learn something new I think :coffee:
