Title blend fixjwrlTitleFix.fxKeyJanuary 4 2020November 14 2020

This effect enhances the blending of a title, roll or crawl when used with external blending or DVE effects. Because it has been developed empirically with no knowledge of how Lightworks blends titles internally, it only claims to be subjectively close to the Lightworks effect.

The three titles in the screen grab above show you:

  • Standard title effect: what you can expect to see when using the title effect as it has been designed to function. Note that the drop shadow is strong and clearly visible.
  • Blended title effect: this is what happens if you need to control the title with a DVE or blend. To be able to do this you absolutely must disconnect the input to the title effect in the routing panel. This changes the way that the title behaves. Note that the drop shadow has now almost vanished. There is also a subjective effect of the edges softening.
  • Title blend fix effect: this is exactly the same setup as with the blended title effect, but the title blend fix has been added between the output of the title and the input of the DVE or blend. Note that the drop shadow is again strong and clearly visible and looks almost identical to the standard title effect, and the edges are again clean.

It also includes the ability to smooth and antialias text produced by a Lightworks text effect. This can be particularly useful when moving or zooming on a title. I suggest a start point setting of 10%. That's completely subjective, and will almost certainly vary depending on text size and style. The screen grab below shows the improvement in smoothing that you can expect to see. If you don't need that ability at all, leave it set it to zero and the antialiasing will be completely bypassed, reducing the GPU load.

Finally, here's an example of the routing that you would use to combine a title with a DVE effect when using title blend fix to clean up the blend. To do this first apply the title, then this effect, then the DVE. Open your routing and connect the video layer directly to the Bg input on the DVE, then disconnect the video from the input to the title.

VibrancejwrlVibrance.fxColourJanuary 4 2020November 14 2020

This simple effect just adjusts the colour vibrance. It does this by selectively altering the saturation levels of the mid tones in the video. You can probably think of it as a sort of gamma adjustment that only works on saturation.

White and black balancejwrlWhiteBalance.fxColourApril 23 2020November 14 2020

This image is hidden for guests. Please log in or register to see it.

This is a simple black and white colour balance utility. If your whites aren't really white or your blacks aren't really black this could really help. To use it, first sample the point that you want to use as a white reference with the white eyedropper, then get the black reference point using the black eyedropper. Switch off "Select white and black reference points" and set up the white and black levels to give the effect that you need.

The screen grab above shows the before (left) and after (right) level changes when the effect is applied. As you can see, apart from adjusting blacks and whites it has also partially corrected a red bias in the original shot due to the late afternoon light. To truly nail that sort of problem though, you will probably need to adjust the colour gamma as well.

This is a quick simple cropping tool that you can set up by dragging corner pins around on the screen. In effects settings mode, move your mouse over your edit viewer and two diagonally opposing corner pins will appear. Just click and drag and the crop will follow. Done. It's one of those "why did no-one think of this sooner" tools.

Visual motion blurjwrlVisualMotionBlur.fxStylizeJuly 9 2020November 14 2020

This image is hidden for guests. Please log in or register to see it.

This is a directional blur that can be used to simulate fast motion, whip pans and the like. This differs from other blur effects in that it is set up by visually dragging a central pin point in the record viewer to adjust the angle and strength of the blur. I have added the centre point cross to the screen grab for clarity. It isn't displayed during effect setup.

This image is hidden for guests. Please log in or register to see it.

This effect is a transition that pinches the outgoing video to a point to reveal the incoming shot. It can also reverse the process to bring in the incoming video.

The direction swap has been deliberately made asymmetric. Subjectively it looked better to have the pinch established before the zoom out started, but to run the zoom in through the entire "un-pinch" process. The effect progress is non-linear to make the acceleration appear smoother.

A quick look at xPinch_Dx or xPinch_Ax, xPinch_Adx will show you what it does. You will find an explanation of how to use alpha transitions in this post and delta transitions in this one.

This effect performs a whip pan style transition between two sources. Unlike the similar blur dissolve effect, this also pans the incoming and outgoing vision sources. It provides quick setup of vertical and horizontal whip pans and requires no fiddly setting up of the individual source blur angles. Because of the source mix that it does during the blur, it also gives a more convincing whip.

A quick look at WhipPan.mp4 will show you what it does. The example is a one second pan, but the effect is probably shown at its best in the 12 - 15 frame range.

The alpha and delta versions are designed to whip a title on or off screen. WhipPan_AxAdx.mp4 shows the alpha and delta versions using a title effect first, then an image key.

Crawl and roll fixjwrlCrawlRollFix.fxKeyJuly 19 2020December 28 2020

This image is hidden for guests. Please log in or register to see it.

This effect provides a simple means of smoothing the movement of a credit roll or crawl. It does this by applying a small amount of directional blur to the title. It then blends the result with the background video.

To use it, add it after your roll or crawl and disconnect the input to any title effect used. If you're smoothing an existing video roll or crawl, replace any blend effect with this effect. Select whether you're smoothing a roll or crawl then adjust the smoothing to give the best looking result.

This effect is a customised version of the Lightworks Chromakey effect with cropping and some simple DVE adjustments added. Also added is a means of generating an infinite cyclorama style background. The colour of the background and its linearity can be adjusted to give a very realistic studio look.

Foreground glowjwrlFgndGlow.fxStylizeOctober 16 2020November 8 2020

This image is hidden for guests. Please log in or register to see it.

This effect uses a glow based on the Lightworks glow effect to apply a glow to just the foreground component of a blended image, image key or title. The background remains "un-glowed". The effect can be applied to a title or video with transparency by first disconnecting any input or blend effect, or the foreground video can be extracted. In that case it is separated from the background by means of a delta or difference key.

The blend option used for the glow is a subset of the standard blend modes widely seen in art software. If using this to add glow to a Lightworks title or image effect you will need to disconnect the input to them. This effect will take over any blending required. If using the delta key this additional blend stage is bypassed. In delta key mode it works with already blended images without the need to break the blend.

The "Feather" and "Colour" parameters only operate when using luminance as the glow source. This is identical to the behaviour of the Lightworks glow effect.

Truer sepiajwrlTruerSepia.fxStylizeAugust 2 2020November 14 2020

This image is hidden for guests. Please log in or register to see it.

Why Truer sepia? Because there are an awful lot of so-called sepia tone effects that create a rough and ready black and white image then colour that so that the lightest areas of the image are at least as strongly coloured as the darkest, and often even more so. That is not the way that sepia toning works!

Sepia toning is a chemical change to the silver molecules that we see as black in a photographic image, so obviously the lighter parts of an image cannot be as strongly coloured as the darker parts. This effect is a very determined attempt to get as near as it's humanly possible to provide the look of a true film based sepia tone. At it's strongest you will notice that the lighter areas appear almost white - which they should do.

Secondly, sepia toning affects the less dense areas of the image first, so that the lighter tones will colour before the darker ones do. For that reason, in this effect as the sepia tone is increased the effect converts the image progressively, starting with the whiter (lightest silver density) areas first.

Thirdly, sepia is definitely not red-brown!!!! Silver sulphide (silver sulfide if you're American) is a yellow-brown colour. If you've ever changed a baby's nappy (diaper if you're American) you'll know exactly the colour that I mean. Silver sulphide is the chemical that gives you sepia toning. The colour of the sepia tone has been visually matched with old photographic prints to be as close as it's possible to get. No baby's nappies were checked.

Four different black and white conversion profiles have been supplied. There is the standard video luminance conversion, a modified RGB average, and two that mimic panchromatic and orthochromatic black and white filmstocks. Each profile can have its exposure adjusted by plus or minus one stop so that you can finesse the look to your satisfaction.

There is one final characteristic which I have chosen not to directly provide. The silver sulphide molecule is larger than the metallic silver one: this has the effect of increasing the contrast somewhat in a sepia toned image. This means that as sepia toning increases the contrast should also increase up to the point where the toned image begins to fade with age. I have chosen not to provide that. There should be enough range in the exposure setting to cover it should you need it.

Multiple tonerjwrlMultiToner.fxColourAug. 3 2020November 12 2020

This image is hidden for guests. Please log in or register to see it.

Multiple toner aims to produce the effect of a range of chemical processes that can be applied to black and white prints. The tones used are generic, and the black and white conversion approximates the spectral response of panchromatic film.

The sepia toner attempts to get as close as possible to the classic Ag2S chemistry. It closely matches the look of sepia toned photographs that have been compared with it. In common with all of the toner types supported, the strength setting acts on the lighter coloured areas of the image first. This is what actually happens with thinner emulsion areas of images in the real-world chemical process.

The selenium toner has two presets because the actual colour produced is seriously affected by the chemistry of the paper used. The brown toner is similar to what you would expect with bromide papers, and the purplish version comes closer to the look you get with chloro-bromide papers. However even with the best care and attention given, how well the results match can only be subjective.

I've had to rely on on-line reference images for the gold toner. As far as I'm aware I've never actually seen one "in the flesh", so to speak. I've opted to emulate a combination of gold/sepia, which is a reasonably common toning process. The blue-black of pure gold toning didn't looked as interesting. This one comes close to the dark chocolate look of Agfa's Portriga paper, if anyone can still remember that beautiful paper stock.

Copper toning can vary from the reddish tones that you see here through to quite green or even blue depending on the print's age and how it has been stored. I've just picked a colour and contrast setting that had about the right look.

The blue in the iron toner is not in any way similar to the prints produced by the ferrotype or tintype process, and is not intended to be. I've based it on the look of blueprints, because the chemistry that produces that colour is identical to the chemistry in a treated photographic print. It's an image transfer process rather than a direct toning operation and is an effect I've only read about in old photo chemistry books. I have never actually seen it anywhere except on-line.

Optical fade downjwrlOpticalFadeDown.fxFadeDec. 31 2018July 30 2020
Optical fade up OpticalFadeUp.fx

This image is hidden for guests. Please log in or register to see it.

These two effects simulate a film laboratory optical printer fade up from black or down to black. They are applied in the same way as you would apply a title effect, i.e., by marking the region that the fade in or out is to occupy. The screen grab above shows the way the effect appears at the halfway point of a fade compared to a standard fade. It has a much more dramatic feel than a standard fade.

You should play OpticalFade.mp4 to really see how it feels. If you want both effects you will find them together in OpticalFades.zip.

Rainbow v2jwrlRainbow_v2.fxStylizeAugust 8 2020November 15 2020

This image is hidden for guests. Please log in or register to see it.

This is a special effect that generates single and double rainbows. The blue end of the spectrum has adjustable falloff to give a fade out that is more like what happens in nature. The rainbow is blended with the background image using a modified screen blend that can be adjusted in strength according to the inverse of the background brightness, i.e., the brighter the background the fainter the rainbow. The softness of the blend mix can also be adjusted. The default crop settings will produce a 90 degree arc (plus and minus 45 degrees), but can be adjusted to whatever angle you need over a 180 degree range.

The secondary rainbow is inverted (i.e., VIBGYOR instead of ROYGBIV) and inherits Amount, Radius, Width, Falloff and Origin from the primary rainbow. For the secondary rainbow the master Amount is modified by the secondary rainbow Amount, and master Radius and Width are modified by the secondary rainbow Offset. The secondary rainbow's crop angle and feathering are independent of the master rainbow settings.

NOTE: There is currently another rainbow effect in this thread called Rainbow. This effect does all that effect does as far as rainbows are concerned, but does it better. What it doesn't do is moondogs, but hey! You can't have everything.

This effect creates the classic binocular mask shape. It can be adjusted from a simple circular or telescope-style effect, to separated circular masks. The edge softness can be adjusted too.

For that additional touch of reality colour fringing can be applied to the edges of the mask as shown in the screen grab above.
