Hi @alexiscn
Great job on MTTranstions! Do you have any upcoming plans for additional features?
I was considering to work on a similar project, but it would make more sense to contribute in your repository if you're still actively developing it.
I think these transitions could be used in a high-level context, similarly to the UIViewController transitions which you've already implemented. My idea would be to create an UIKit compatible transition effect which could be applied on any UIView subclass.
If you are interested let me know and I could share an example here!
Incorrect argument label in call (have 'cgImage:isOpaque:', expected '__cgImage:isOpaque:')
Replace 'cgImage' with '__cgImage'
Hi , i am using this library and its way too good but i am stuck when trying to add dynamic duration to each image in array
for example there are 6 images and adding duration to each image like [0.0,4.0,2.0,0.5,5.0,6.0].
it only works fine when i am adding static duration for all images like [2.0], then all images duration will be 2.0.
Pleas help me to provide flexible duration for each image while creating video of images.
Below is the Error:-

I want to use filter on video. thats why is use VideoIO. filter work but the problem is transition.
` func videoFilterSet(){
guard let result = result else{
return}
let context = try! MTIContext(device: MTLCreateSystemDefaultDevice()!)
let handler = MTIAsyncVideoCompositionRequestHandler(context: context, tracks: result.composition.tracks, on: .main) { request in
self.filter.inputImage = request.anySourceImage
return self.filter.outputImage!
}
let composition = VideoComposition(propertiesOf: result.composition, compositionRequestHandler: handler.handle(request:))
let playerItem = AVPlayerItem(asset: result.composition)
playerItem.videoComposition = composition.makeAVVideoComposition()
player.replaceCurrentItem(with: playerItem)
self.player.seek(to: .zero)
self.player.replaceCurrentItem(with: playerItem)
self.player.play()
}`
please see this code for filter
Hello,
I'd like to merge two videos using these transitions. There is only MTIImage and I can't use the transitions for video processing.
Please let me know how to implement the video transitions.
Thank you.

I used MTTransition latest version, my project is developing by using SwiftUI. The user merges clips and playing the video, when playing the video, the user should see the transitions.
Hello,
I'm using the library to make transitions between clips. It works fine 1 or 2 times, but after that I have a crash related to memory. I can see the memory inspector which increases the memory leaks after each processing. I'm using the merge function.
Please add Swift Package Manager it this project. Every one moving SPM .

I am taking one portrait video and one landscape video.
Now at the time of transition my landscape video gets aspect-fill and after that it gets aspect-fit.
Hello Team,
you made great example of transition between videos but when I use your library its always gives me wrong orientation video. can you please help me for the same.
Thanks in advance
I'm trying to use this library to add transitions between movie clips selected by the user but it doesn't apply the correct video orientation to the output.
TLDR: i'm selecting 2 portrait videos and the output shows them in landscape with the transition effect in portrait.
