Step up your masking game because it is time for Dynamic Masks! With this filter you can use any other source as a mask for any other source, and decide just how that mask should be applied. Don't limit yourself with boring old Image Masking and just use literally any kind of video source to mask content!

Signed Distance Field Effects have also now gained the ability to render Glow and Outline, which can be used for making things glowy and outliney. Note that as OBS Studio does not support per-pixel blend operations, or any blend operations at all, the default Mix blend will be used with no way for me to change it. In addition to that, the effects will now look better than before, and should no longer have unexpected pixely outlines when using Inner Shadow or Inner Glow.

Various smaller fixes have also been applied, such as that the source tracking code now actually tracks renamed sources correctly instead of permanently showing the old name. Some properties will now have different hover text descriptions depending on the selected option, and the Displacement filter should no longer crash unexpectedly.

The big blur rework has finally reached an end, because today I present to you the new, more efficient, better Blur design! It comes with a new blur type called Dual Filtering, which can do the same work as Gaussian Area blur, but at much less cost.

Two new blur subtypes are also now available, called Rotational and Zoom blur, which can be used to simulate a rolling camera or a forward/backward moving camera. Clever uses of this can result in some really nice art for the background, especially if you have some sort of visualizer. The maximum blur size has also been increased from 25 to 127.

Next is Source Mirror, which has now gained the ability to mirror Scenes without requiring OBS Studio v23.x or newer, and no longer freezes OBS Studio when you open the filters dialog with audio mirroring enabled. It also stops rendering video if there is nothing to actually render, and will no longer cause audio stuttering or skipping if audio mirroring is enabled.

It is finally time for Version 0.5.0 to be released to the general public after it has spent a month in Early Access on my Patreon! This version brings along a lot of needed fixes, performance improvements and new features. And most of this was done in the total work time of 3 months, in which the main task was fixing bugs, crashes and leaked sources.

After that, lots of time was spent optimizing Filters and Sources so they no longer cause top of the line GPUs to barely be able to render at 60 fps. This was mainly done with optimizations to the actual shader code and by caching the result of the render for each frame, instead of rendering it anew each time. This makes Studio mode, the Properties view and the Filter editor no longer cause a frame drop.

And finally, a few new Features have been added. Source Mirror now has Audio Mirroring and proper rescaling, Blur Filter supports masking and Directional Blur and 3D Transform now has mipmapping. And there is also a new kind of Filter: Signed Distance Field Effects! This Filter can be used to apply a shadow to a source, as long as there is any kind of transparency as it works by dynamically creating a Signed Distance Field which is faster than normal blur, and allows for a lot more effects.

Changelog
Source Mirror Source
  • Added Audio Mirroring which allows applying filters to an audio signal of a mirrored source.
  • Added support for Rescaling similar to that which OBS Studio supports.
  • Fixed various source leaks that caused issues, such as crashing or not allowing Video Capture Source to release the device.
  • Fixed various crashes due to missing references with Sources that only have Audio or Video.
  • Now supports cached results per frame to reduce GPU and CPU usage each frame.
Blur Filter
  • Added support for masking with various mask inputs, such as region, image, source, or scene. This can be used to create effects like this or this (by DTOX).
  • Added linear sampling versions of Box and Gaussian Blur which uses about 50% less GPU.
  • Added Directional Blur which can be used for something similar to Motion Blur.
  • Added Step Scaling which allows lower blur sizes to affect a larger area.
  • Fixed the Gaussian Blur kernel size not matching up with the actual range of the blur, resulting in a box effect instead of a smooth blur. Compare the old behavior with the new behavior for this sample image to get an idea of what it changes.
  • Optimized various shader invocations to use arrays instead of textures.
  • Now supports cached results per frame to reduce GPU and CPU usage each frame.
3D Transform Filter
  • Added Mip-Mapping to reduce aliasing and pixel flickering for angled, scaled, stretched, squished, sheared or otherwise transformed source. This option is only available for DirectX currently and still considered Experimental.
  • Fixed the squishing/scaling bug when the input Source unexpectedly changed.
  • Fixed various crashes due to lost references and invalid pointers.
  • Now supports cached results per frame to reduce GPU and CPU usage each frame.
Displacement Filter
  • Improved quality by no longer relying on bootleg versions of PS2.0 instructions.
Signed Distance Field Effects Filter
  • A new effect that allows for many types of effects, such as Shadows, Stroke/Outline, Glow and more. It uses a dynamically created Signed Distance Field which allows for much higher accuracy and quality, but is not able to quickly catch up to sudden changes at full resolution.
It's been over a year since the last full release for Stream Effects, and we're getting ever closer to another one. With this preview release a lot of bugs and crashes have been fixed, new features have been introduced and some even got a much needed upgrade. For example, the plugin now has an Installer like the one for the AMD Encoder!

The most important change is that Blur Filter will now take up to 99% less GPU to run, which means that you can go nuts with the effect even more than you could before - and maybe even go back to a 2-PC streaming setup if you switched from that to a 1-PC streaming setup. This is the result of lots of changes to the rendering system (see changelog). Additionally you can now use a Mask of various types (Region, Image, Source, Scene) that will restrict blur to only apply in the masked section.

Next up is 3D Transform which now supports mip-mapping, a technique used to smooth out pixel artifacts when the texture resolution is greater than the screen resolution, for example if you rotate, shear, scale or modify the source geometry by other means. For people using 3D Transform to place objects into a 3D-like scene, this means drastically improved image quality at the cost of some extra GPU memory and time. This is currently a Windows/DirectX11 only feature and will not have any effect on other platforms or renderers.

Then we have the all new Filter "Signed Distance Field Effects"! With this you can apply an Inner Shadow, Outer Shadow (aka Drop Shadow) and in the future Glow and Outline too. It is a cheaper alternative to blurring a source for a shadow or glow, but it does reduce the shadow/glow quality slightly.
Finally we have Source Mirror which can now finally mirror audio and has gotten some rendering and stability upgrades. It will now no longer cause sources to be endlessly active and has all new re-scaling options.

Changelog
Overall
  • The plugin now features a brand new Installer similar to the one present in the AMD Encoder for OBS Studio plugin. This should simplify installing the plugin a lot.
  • Backwards compatibility up to Version 21.x has been restored, which means that you can now use newer OBS Studio versions as well as old ones.
  • Translations can now be submitted via CrowdIn! Translate Stream Effects into your language today!

Today I bring you the "Source Mirror" source and a bunch of fixes. The "Source Mirror" source allows you to create a mirror of an existing source which can have its own list of filters and can even rescale your source for performance reasons. No need to painfully work around a core limitation in OBS Studio anymore!

Additionally, the 'Blur' filter has received a much needed update. It will now work as long as the GPU is not broken, several potential crashes with it were resolved and Gaussian Blur now has correct colors too.

Hotfix: Fixed 32-bit crashing instantaneously and also improved overall performance and stability.
