This post is for sharing the customized transitions you have made based on the explanation: https://www.vegascreativesoftware.info/us/forum/vp19b458-gl-transitions-feature--133471/

Custom presets are stored in:

C:\User\<username>\Documents\OFX Presets.

And as for this GL Transitions, can be found in:

C:\User\<username>\Documents\OFX Presets\de.magix_glTransition\Transition\

Looking forward to see your unique transition, code, example, and how to 'install' if preset modification is needed

Personal opinion:

This is an extremely interesting customized transition with modern feel ever made. Love this one and easy to use.

Looks unique and modern, fits for technological or tutorial movies.

fr0sty wrote on 3/15/2022, 1:49 AM

First scripting, now transitions, I really think team VEGAS needs to keep putting more customization options into the hands of users who can write their own code, which then creates a thriving community of users sharing their customizations. I think it would be cool, for instance, for a user to be able to create their own version of the preview window, with added functions, or create custom skins for VEGAS. that last one especially, you will never please all users with aesthetic decisions made, but if you let them customize the look themselves completely, they can skin it however they like and everyone is happy.

3POINT wrote on 3/15/2022, 2:39 AM

To my opinion, Vegas has more than enough functions to customize the UI, customize toolbars, customize windows, customize through burger menu etc. I personally rather like to spend my time with editing than with customizing the Vegas UI or customizing/designing transitions/scripts, etc.

By allowing users to customize VEGAS to their needs, both people like you and those who desire more out of the interface/functionality can have what they want, and the developers don't have to lift a finger beyond the point of enabling it.

Agree. VEGAS has lots of customization options. At this moment, stability, speed and codec support is much more important.

fr0sty wrote on 3/15/2022, 9:46 AM

What VEGAS needs first isn't my point, I'm just saying that by enabling users to customize VEGAS further, it is nothing but a good thing. If you don't like or need it, nobody would be forcing it on you, but those of us that would benefit from it, to have the option and a thriving community of people developing content that enhances VEGAS I see as being beneficial.

We all know that VEGAS needs certain things as soon as can possible get them, I too would rather see performance and stability continue to catch up.

RogerS wrote on 3/15/2022, 10:17 AM

Back to the point of this thread, Is anyone making commercial GL transitions? So far we have code for 1 generously offered here. I don't think I'll ever learn how to make them but if there were some for sale I'd consider it.

alifftudm95 wrote on 3/15/2022, 10:55 AM

can someone recreate this transition with the GL? I requested on the Github community but no luck.

JackWhite wrote on 3/16/2022, 7:46 AM

Thanks @boundless-beta. When I add the script to the default GL transition I just get a black screen with "invalid shader" in res text where the transition should be. Am I doing something wrong?

jetdv wrote on 3/16/2022, 8:33 AM

@alifftudm95, that's actually not a "transition" but an effect added to the left and right sides. Those can be set up using my Christmas gift:

https://www.vegascreativesoftware.info/us/forum/free-transitions-a-b-extension-merry-christmas-from-jetdv--133460/

I do think it's definitely possible an actual transition could be made that does the same thing, though.

lan-mLMC wrote on 3/16/2022, 9:08 AM

@jetdv This new form of "transition" is called "seamless transition" by Premiere users.

jetdv wrote on 3/16/2022, 9:19 AM

@lan-mLMC, all I can see is that he split the end/beginning of the clip into a separate piece so the effect wouldn't affect the entire clip and then simply added a different effect to each side. Technically, not a transition but effects added to each side. In the video you posted, it looks like they're actually using other clips to "cover up" the transition between the clips.

I still believe that "look" could be done as an actual "transition", though. But the Christmas Gift allows setting up "transitions" using effects and even allows adding keyframes to make them last the proper length without needing to "split" the clip on the timeline.

@jetdv

Yeah, it's not transition in the traditional sense if we judge it from the way the video makers create it.

But from the audience's point of view, it's a really cool transition. No difference from the traditional transition, even more stylish and cool.

And it has one more obvious superiority over traditional transition: It doesn't require events to overlap, so adding this transition doesn't disrupt the existing structure of the project timeline.

This is really important for making videos, we can first edit and arrange all the clips, and then we can add these transitions finally ( Don't worry that it requires overlapping events and messing up the timeline ) , which is very efficient.

I know this (usefull and beloved) feature from my other NLE, where I can decide between an overlapping or a cross transition. A cross transition doesn't disrupt the structure and gives the possibility to add transitions finally. Not each transition is suitable to give a seamless cross (like a fade) but a lot of transitions are suitable.

@3POINT I agree, I've never said that the new form of seamless transitions can completely replace traditional overlapping transitions, because some transitions must have two events in the same one frame (like cross fade, window-blinds ).

However, when both forms of transition are suitable, the new form of seamless transition has the advantage of being more efficient (no overlap is required to disrupt the timeline; More stylish and cool).

==========================================

I know this (usefull and beloved) feature from my other NLE, where I can decide between an overlapping or a cross transition. A cross transition doesn't disrupt the structure and gives the possibility to add transitions finally.

I will not adopt this method of PowerDirector, because it makes the last frame of the previous event stand still, and the first frame of the next event stand still, so as to avoid overlapping. This makes the frames suddenly stop while the video is playing, which is a very strange visual experience and makes people uncomfortable to watch. I generally don't recommend using this method.

3POINT wrote on 3/16/2022, 1:26 PM

As I said not every transition is suitable, but in Powerdirector a lot of seamless transitions are suitable for crossing instead of overlapping and that without a freeze of last and first frame.

fr0sty wrote on 3/16/2022, 2:17 PM

I downloaded some transition pack on youtube that used BCC to do all of those fancy zoom transitions, but I can't remember where it was. It worked the same way, you didn't overlap the clips, you just applied an effects preset to them and it did the rest.

3POINT wrote on 3/16/2022, 5:07 PM

@lan-mLMC a short example of a simple edit without transitions and the same edit with seamless cross transitions:

Adding the cross transitions didn't disrupt the edit or it's length. This wouldn't be possible to do in Vegas where only overlapping transitions are possible.

I should have mentioned that this code block was formatted for the preset file mentioned in Example 3 of this post.

Open that file and paste the code just above the last line with "</OfxPresetPackage>". You will need to restart VEGAS Pro afterwards. If done correctly, the transition should appear at the end of GL Transition's preset list.

Thank you for further explanation... Yes, this is extremely important, to paste the code before last line </OfxPresetPackage>.

Yet all presets are customizable... great job!

Indeed, I have Vitascene4 LE with my other NLE and I can say it has high quality tools. I also received 3 months complimentary full version and it worked well with my VMS16P. I wonder why it never bundled with Vegas...
