wwwmaze,
wouldn't it be a good thing to have video folders behaving the same as audio folders? I mean, imagine how easy it would be to handle title animations separately from scene transitions etc. It only needed a last instance like opacity to plan and organize everything. But I'm still amazed by your presets. I downloaded SynfigStudio and made within a minute an own black and white transitions. That's so easy. You can practically do anything in 2d. The other way to create nice alpha effects would be to use the "cheap brightness and contrast" preset with simple video snippets. Film some waves on a lake. Put it in Reaper. Choose the "cheap brightness" effect on it to desaturate and darken it until its nearly black. Then animate the contrast or brightness (extreme settings are possible) to make the transition to white. So here is the quick synfigStudio test. Its a bit weird in timing but was made in a minute after first time opening this software. Now we see which powerful tool you have created. |

Just a few greyscale rectangles moving from left and right, getting bigger and brighter until everything is white.

With alpha you can do tons of cool stuff. Really great that wwwmaze created those great presets. Kaleidoscope is amazing. Blending also. I'm amazed how helpful can one script be. I hope wwwmaze keeps writing great presets for video processor. Big thanx.

Not very user-friendly but afaik there's no other choice currently. Quote:
You basically just can use another video as mask. |

a way to desaturate the dark areas would be nice. Sometimes I'll do a rough color adjustment and end up with blue or purple dark areas but I'd like them to stay black. In color grade software this would be "Luma vs Sat"

This is really cool. I see this as a great leap for the video capabilities of Reaper. Great job folks!

You could easily do this with gfx_evalrect()...

One last thing I wanted to show just to present whats possible with masks now.
This is only a campfire at night. I put it on the video b track and in the mask track without any manipulation. So the mask channel just uses the black and white data to only let the flames get thru. This way you could use snow, rain etc. in front of a black background to mix it in your videos. Very nice. Lots of free campfires to test out: https://vimeo.com/93091275 |

This is a neat trick. The fire at the ridge actually looks pretty realistic.
I was thinking about for that it would be handy to have some additional parameters to stretch/compress/boost the histogram/contrast of the mask, but then decided it would be best done as separate FX ahead of the input. |

Stretch-compress the histogram ... sounds pretty exciting. I'm coming from Photoshop where this is the first thing you have to do with every new picture: Arranging the levels to get the widest range.
So I hope you get bored and nothing special happens in your next free time. |

This is a pretty old thread, but I've been referencing quite a bit, and it has been very helpful. That initial blender thing (post #15) is something I've wanted for quite a while. Took me a minute to figure out how to make it work, and I've got some ideas for improvement that I'm going to work on here in a bit. I did find that this:

I learned a lot from reading this thread and came up with a few tricks of my own, for example, using a mask to add rounded corners to an overlay (picture-in-picture). I compiled everything in this video:
Thank you all for your work 😀 |

Thanks for this preset!
I recently worked with a yuva420p-encoded video with transparency, but REAPER doesn't seem to recognize the alpha channel. To solve the problem, I extracted the alpha channel to a separate greyscale mask, and then used this preset to apply the mask as transparency. I noticed that the preset doesn't seem to work if it is on the same track as one of the layers. I don't know much about video scripting, but the following hack seems to work: Code:
//@param10:offsBg 'track offset bg' 1 0 20 10 1 //@param11:offsFg 'track offset fg' 2 0 20 10 1 //@param12:offsMask 'track offset mask' 3 0 20 10 1 bg=(offsBg==0)?0:input_track(offsBg-1); fg=(offsBg==0)?0:input_track(offsFg-1); mask=(offsMask==0)?0:input_track(offsMask-1); |

Hi folks,
is it possible to apply the mask only to a portion of the screen ? I need to create a lower third animation and I'd like to mask only a very few part of the screen. Some width /height x/y options ? Any workaround ? |

Hello Papagirafe !
thanks for your anwser, but unfortunately, I can't acheive my project even with this preset. I'd like to make the same animation than this one : https://www.youtube.com/watch?v=KEjZH1PRYPk I wonder if it was possible do do it in Reaper, but for now it seems to not be possible, at least easily. Nevermind, Kdenlive is a quite good tool |
