can someone help me with a simple mirroring problem?

[1000errors]

This is something I've been doing in modul8 for a while now but since swapping to resolume I presumed it would be really easy to also do. All i want to do is just a simple horizontal mirroring of an entire video (not just mirroring half the video). These pics explain what I'm trying to acheive better than I can explain in words. If anyone could help it would really be very much apreciated! thanks

It's dependent on the size of the original image, but one way to accomplish this is to resize and position on the clip level, and then to apply a horizontal flip set to add blend mode and 50% opacity on the composition level. Hope that works for you!

Hello, thanks,
although that does solve the problem if i was only using one layer I wasnt really wanting to mirror the entire composition.
is there any way of doing this without mirroring the entire composition?
thanks

Figured that might be what you're after

As far as I can tell, this is not possible. Scale and position translations are applied first, and any effects will be applied on the resulting image dimensions (this is done to speed up rendering, because you don't have to render a lot of black pixels that way).

The only two options you have (in my opinion), is to render out your video at the desired size and location, leaving space on the right to have it flipped. Another option is that perhaps someone from the FFGL community will be able to make an effect out of this, which handles the flipping and translation in one go.

Having said that, we are taking a good look at how we can give you more options for when things happen in the render pipeline for future versions of Resolume.

Hope that explains things a bit.

Hi, thanks for getting back to me again.
The solution you offered kind of worked but it would make more sense for me to mirror it in after effects than squish the video to half the desired size then mirror it resolume.
The reason I have found it so handy to be able to mirror videos in this way (and to use tiling) on a video in the way I have mentioned is that some of my videos can be quite small in size but i can make them stretch across a whole composition without having render larger videos this way. It also gives me more flexibility to use the same footage in compositons of different aspect ratios without having to loose the original proportions of the videos by stetching or squashing them.

Here's an example from a video I have made that uses this technique several times.


As you can see the city in the middle ground I have used tiling and mirroring on it to make it stetch across the compostion which is much larger than the video itself, the foreground mushroom layer at the bottom is actually a really small video that has been tiled probably about 5 times.
Although you cant really see it well, the sky is a video only half the width of the compostion that I have mirrored so that it fills up the whole compostiton without having the stretch pixels and loose quality ect.
I'm quite new to resolume so maybe this is something i've overlooked, but these features combined, tiling and mirroring in this way I have found exteremly useful in modul8 and it would be great if resolume had them too, maybe I should be writing this in some feature request section instead.
anyway thanks again for you help!

What would be helpful is to implement an FFGL plugin called "Transform" that does scaling, position and rotation, matching the attributes in the clip properties, then you could insert these transforms anywhere you wanted in the effects chain.

After Effects does this: they have Transform properties for every media item, but also an identical Transform effect that you can drop in anywhere in the processing chain.

In this case, you could have a Transform effect to move the clip to the side, then another Transform with a negative X-Scale, and you could still use the clip properties to move the clip within the frame.

Yup, I was thinking something along those lines as well. Shouldn't be too hard to do actually.

hey, thanks for the reply, if someone could make this plugin it would be incredibly helpful to me.

At the mo I'm having to do all the mirroring/tiling stuff in AE then render the clips out 1280 wide to use in resolume. If I had the ability to mirror and tile in resolume some of my clips would only need to be 160 wide and tiled 8 times. I imagine doing the tiling within resolume is a huge advantage for saving system resources that could be used on doing more important things other than just playing large video files that needn't be so large in the first place.

If someone is considering making this plugin I would also request that it is able to tile and mirror the video along the y axis as well.
Thanks so much if someone can do this!!
also please get back to me to let me know
