Hi guys

I finished editing my first video using LumaFusion yesterday and I can’t believe how well it performed.

I used 14 2.7k Phantom 4 Pro mp4 video source files to create a 2’50” video and the app worked flawlessly. There were minor glitches but nothing bothering. For example in full screen preview the pkayback would hold for a bit but pausing it and resuming brought the speed back to normal. Also I would have liked a way to be able to replace source clips without deleting them from the timeline, I could not find how to do that so for example each time I made a change to the music I had to delete it from the timeline and add it again. Also I would’ve loved to be able to do some speed ramping as I speed up the clips a lot. Anyways that is prety much it, no other problems.

Now the philosophical question:

I am not able to understand how an app that costs only a few bucks used on an Ipad Pro 9’7 can outperform Premiere Pro CS6 or Davinci Resolve used on my Surface Book. Can somebody explain that to me? I’m very very curious what the magic is. I mean, the Surface Book has 16Gb of RAM, dedicated Nvidia GPU, I7 Intel CPU, 512 GB SSD and the tablet.... well, no GPU, only 2 GB of RAM and almost no disk space. I just don’t get it

Thanks for taking the time to read this.

First, thanks for your kind words, and I've filed a bug report for your Preview bug.

Second, I can tell you that we've got both of your feature requests (replacing media without erasing from timeline, and keyframe options for speed control) high on our radar!

Third, to address your philosophical question: From a technical aspect, Apple has built many frameworks themselves that optimize the manipulation of Audio and Video - for this reason we are not currently working on an Android/Windows version of LumaFusion, as it would require us to build equivalent frameworks to use on those non-iOS platforms, which would take a very large team, and a lot of time. So these Apple Frameworks give us a lot of headway to work on further optimization of multiple instances of Audio and Video manipulation (which is how we accomplish 3 Audio and 4 Video tracks). Let this also shine a light on the equality between software quality and hardware specifications, while having quality hardware is necessary for smooth performance, it is not the end-all be-all for how smooth software operates (though we hope to see improvement on Apple's hardware to accelerate the performances gained from their frameworks). And maybe the most important bit is that we have a very experienced Head of Engineering who is able to push the Apple frameworks to their full potential, and then some.

Thanks for reaching out! We're really happy you enjoy the app :D
Keep us posted with any other bugs or features you'd like to see.
