Black border

PostWed May 18, 2022 4:42 am

Why is there a black border in the viewer on Edit tab? When I turn on full screen mode and create a screenshot, it contains a black border. Please remove it.

P.S.
I also noticed something else. I think these lines make the video a little blurry. I open the video in the player and the image is clear. But as soon as I drag it into Davinci, the text gets a little blurry. And it's only blurry in the Viewer on the Edit page. When I save the video, the image is clear.

I see it too, even with normal video.

Studio 18b3 on Windows 10.

Not sure this one is a Feature Request, though. Seems more like a bug report.

It's possible that that is deliberate so you can see the true edges of the frame, similar to using under-scan monitors back in CRT days.
As Jim says, it's there just playing a video using something like Media Player so has nothing to do with Resolve. In other words, it's normal.

Export a still from the Gallery, open it in the Finder as full screen, screenshot that, and bring it back into Resolve, and it will match the source. But if you go into Cinema Viewer, screenshot that and bring it back in, it has the black border. So yes, its Resolve doing that.

Yeah I use the full screen mode from the Edit page to take a snapshot of the frame... because it's the quicker way instead of going in the color page, grave a still, save it, delete the extra files.

I hope they implement a save still on the edit page

I'm experiencing black borders too. I don't like it. Is this useful for something?

The black border doesn't hide any image flesh; it's just the fullscreen zoom that only goes to 99.9% or something. E.g. when you have 1 white pixel at image position 0,0 you will still see this pixel in fullscreen.

I think the black border is useful when you zoom 1080p material, for example, to a full screen that is greater than 1080. The zoom will generate a smooth anti-alias which may blur certain pixels that you want to detect and avoid. When such a pixel is zoom-blurred, you may detect that pixel not so well, especially if it sits next to the monitor's hardware frame. If you have a small black extra border between hardware and image, you may have better visual control over the anti-aliased image edges.

Example: You have a black sky with white stars, and you don't want to have any white pixels on the outer edges of the image. So you eliminate them with some tools (crop or mask or whatever). The small viewer is too small to watch single pixels anyway. And the fullscreen EDGES are too blurred and too close to the hardware border to watch single pixels at the edge. So you make the fullscreen a tiny bit smaller.

Fullscreen in FinalCut, which I don't use anymore, always zoomed 100% and thus I sometimes missed anti-aliased nuisance pixels at the iMac edges indeed :-)

I do not see the usefulness of this black border and it has never helped me. On the contrary, it's a hindrance. When you make a screenshot, you have to send it to photoshop to cut these unnecessary black borders. If you already add any functions, you should put a checkbox that allows you to enable any such function if you want, and by default they should be disabled.

Who in your audience is watching the edges? If your image pixels are right at the hardware edge like they should be, that will reflect real world experience since your videos won't be shrunk further from the export resolution i.e. there will be no extra border added.

Use the Gallery export function from the Color page instead and there won't be any black borders.

Although screen grab full screen from the Color page is also fine.

Well, in Resolve I have no such problems anyway. In FinalCut I sometimes got wierd anti-alias effects on the edges of solid rectangles that were exactly 1080p high or even higher. E.g. have a completely white image, and on the right half place a black solid rectangle that is supposed to make the right image half black. When watching the exported 1080p video in a browser, for example, the top pixel row was gray instead of black, all across the right image half in the top row. I.e. the black 1080p rectangle had a leak in the top row. When watching this in fullscreen in FinalCut, that gray leak was invisible.

If such effects cannot occur in Resolve, then, yes, of course, the black border is obsolete.

I just tested it now, last 18 beta, I see the black borders (it's wider on the side too).
They should just have something under a right click in the viewer : Save image as,... or "copy image" (and we could past it in the media pool directly, or on the timeline, why not)

My mistake, you are correct. I now instead of just eyeballing it moved the mouse icon to sides and there is indeed a black border in both sides

Nothing to do with lines, image gets blurrier from viewer resampling.
