GiraFX lib 1.02 for the video processor released

[papagirafe]

Hi all!

I am proud to annouce the release of GiraFX lib, a new collection of video processor FX that pushes the video compositing capabilities of Reaper beyond what was believed impossible or impractical. I prepared an HD demo video to help grasp how much this represents a fundamental contribution:


***main features ***

• Introduction of a video mixer that make video mixing behave almost like audio
• positions & dimensions of video objects in % of the selected canvas or source size
• extremely advanced and flexible positioning system for video elements
• consistent transparency handling with non leaky crossfades
• text: shared style definition, flexible text alignment, ability to display only one line at a time out of a large text
• up to 9 sub-canvas (aka video mixers) that can sub-divide your main visual space into regions

The library is *almost* free and it also comes with a full set of tutorials (soon to be completed).

You can optain it here:

*** update: the lesson "Fundamentals" is now part of the free preview. It was supposed to be this way yesterday!
*** update: there is now a starter kit available for just 5$CAD

*** update 2023-09-29: release of v1.01
the preset "girafx: premixer/chromakey (YUV)" has been replaced by the much simpler to use "girafx:mask/chromakey (YUV)". Indeed, A few days ago, I devised a long sought method for extracting the transparency information out of images generated by chromakey YUV. That information is then sent to the alpha layer in RGBA colorspace. There is no need to pre-mix 2 sources anymore.

*** update 2023-10-16 v1.02 released: corrected a calculation glitch on top padding in "girafx:text renderer"
*** 2023-10-17: added GiraFX list of presets in this post
*** 2023-11-06: Tutorial 4: "Positioning, Sizing & Sub-Mixers" released https://forum.cockos.com/showthread.php?p=2730563

Amazing!

Thanks a lot and for putting it on Realinks with the accompaying text! BTW I unlocked the lesson "fundamentals" that shows a simple slideshow project. The library may be practical even for simpler projects with a subset of the full collection. Maybe I could publish a basic version...
Also, for the thumbnails you are mentioning on Realinks, GiraFX is in good position for making it a reality as dimensioning in percentages along with the right sizing policy makes proportions independant of source resolution.

Looks wonderful!

[papagirafe]

Great news for those who want to try GiraFX but are not quite sure they would use it all: I selected a subset of the most essential functions that are suffisant for simple to moderatly complex projects. It includes the related tutorials. Just look for the "Starter Kit" version (starting at 5$ CAD)

Very good question! I'm glad you asked. Here is a more detailed description:

The 5$ version includes only the most essential presets that are suffisant to make simpler projects yet with the following benefits:

• Consistent and non-leaky cross-fades
• Full collection of frames (aka borders)
• Easy positionning/sizing of visual elements inidividually and/or by groups
• Full text support with fully/semi transparent boxes over a background
• Text scrolling line by line from a single source for lyrics videos
• Transitions masks: enhanced horizontal/vertical wipes, vignettes
• Super easy chromakey transparency (aka green screen) in RGB mode
• Basic color/image controls

The 20$ version adds the following functionalities to the starter version:

• Advanced positionings [grid and flower] for object groups
• Textured and gradient backgrounds
• Geometry corrections and advanced size/color/contrast controls
• Video stack controls that allow reusing a source multiple times
• Chromakey (aka green screen) in YUV mode for better visual separation
• Animated transition based on b/w source video from existing libraries on the Net
• Shapes circle/polygon for visual compositions or "surgical masking"
• Full collection of FXs translated for GiraFX + Random deformations.
• Video stack analyzer

Good work. being able to move items priority backwards forwards is a big workflow improvement.

Super! Thanks for your feedback. I used to have unsolvable priority puzzles in my videos that always required patched presets. This is one of the top reason for creating the library. BTW I am aiming to release the second tutorial before the end of the week.

Version 1.01 released

- added new preset "girafx: mask/chromakey (YUV)"
- preset "girafx: premixer/chromakey (YUV)" is now deprecated

v1.02 released

oct 16: corrected calculation glitch on top padding in "girafx:text renderer"

Dear!
I want to display FPS (Frame Rate) on video like the attached file. Can you help me? I've asked for help on this many times but most people don't care
Thanks

Unfortunately, the only available info is the framerate of the project which is constant and known. Not very useful. If you still need that, I can provide you with a simple preset that does just that.

[papagirafe]

I was asked to provide the list of presets included in the library. Quite frankly, I do not know why I did not think of it before, so obvious!
Here it is:

• Key Presets
  • girafx:video mixer
  • girafx:video source
• Background Generators create new background overlays
  • girafx:bg/rectangle
  • girafx:bg/rectangle-gradient

• Text
  • girafx:text/style
  • girafx:text/source
  • girafx:text/time code

What I need is to check the video's Framerate to see if it is compatible with the Project's Frame rate. I often forget to check, this will affect the synchronization of audio with video when exporting audio files to clients.

Like I said, unfortunately this info is simply not available via the video processor functions. The media explorer gives you this info as soon as you click on the file.

Tutorial 4 Positioning, Sizing & Sub-Mixers is now available for full version subscribers. See:https://forum.cockos.com/showthread.php?p=2730563

The positioning & sizing of video elements in GiraFX is a key feature that finally unify all aspects of video compositing in Reaper. Instead of relying on a single video canvas, the library lets you work with up to 9 additional canvases for grouping elements, in effect enabling video sub-project within the main project. After connecting to the right canvas, all sizing & positioning are in relative coordinates to be actualized to real coordinates and sizes in the video mixers at the rendering stage. Provided suffisant resolution of sources, you may work the project in 1280x720 and switch it to 4k without touching a single video item!

I purchased the CA$20 version yesterday.
Is it possible to use text items or region or marker text for subtitles?
I am discouraged to find out that I apparently have to split video items into separate items for each subtitling and write the subtitle text directly in the `girafx:text/source` code in the FX of each item. This requires a huge amount of item splitting and copy/paste work.
I was hoping to be able to use the subtitles as they are, imported and turned into text items with `Script: HeDa_Import SRT.lua` or similar.
It may be a lot of work, but I would be happy if you would consider adding the feature.

I've been doing the vast majority of my video editing in REAPER now for several years, and have been working around the quirks in various ways. I just discovered GiraFX and have purchased the full version.

I just watched the first tutorial and will have a play around.

Thanks for putting in the effort to create this.

I followed the recommendations, added the video mixer to main, added source to take, set the opacity to wet but I'm getting a black screen in the video window

Update: I figured it out, it was my project settings: make sure this is NOT checked;
Always resize video sources to preferred video size
