This is a simple effect to allow removal or addition of the sorts of colour registration errors that you can get with the poor debayering of cheap single chip cameras. It can also be used if you want to emulate some of the colour registration problems that older analogue cameras and TVs produced.

Simple S curvejwrlSimpleS.fxColourApril 29 2020May 1 2020

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

One of a group of three simple effects, this effect allows the user to apply an S-curve correction to red, green and blue video components and to the luminance. You can achieve some very dramatic visual results with it that are hard to get with standard gamma and exposure adjustments in other colour grade effects.

The other two effects in the group are the Vibrance effect and the White and black balance effect. They were originally designed to be used in combination, but of course can be used independently of each other.

Simple starjwrlSimpleStar.fxStylizeApril 11 2020April 12 2020

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

Simple star is a glint effect which creates star filter-like highlights, with 4, 5, 6, 7 or 8 arms selectable. The stars that it creates can be scaled, spun and positioned anywhere you wish. They are not dependant on having an existing highlight in the image to trigger them. They can also be coloured with a user-selectable flat colour or can be mixed with a prismatic spectrum for more dramatic effect.

The four, six and eight pointed stars match those possible with optical star filters and approximate the look produced by those filters reasonably closely. The five and seven pointed stars are absolutely impossible to produce with any real world filter, and have just been included for fun.

Smooth rolljwrlSmoothRoll.fxKeyJanuary 5 2020January 6 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. Simply add this effect after your roll or crawl. No action from the user is required apart from adjusting the smoothing to give the best looking result. Oh, and setting whether you want to smooth a roll or a crawl.

Title blend fixjwrlTitleFix.fxKeyJanuary 4 2020July 2 2020

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

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 Editshare 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 2020January 4 2020

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

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 2020April 23 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.

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

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 2020July 10 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 in the effect.

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 2020July 19 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 Editshare's 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.

Blended glowjwrlBlendedGlow.fxStylizeJuly 24 2020July 24 2020

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

This effect uses a variant of the Lightworks glow effect to apply a blend to the foreground component of a blended image. Unlike the Lightworks glow effect, it supports transparency by allowing the glow to fall outside the transparent boundaries of the foreground. The background is handled independently of the glow, and remains sharp as a result.

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.

Truer sepiajwrlTruerSepia.fxStylizeAug. 2 2020Aug. 2 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.

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

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.
