Hi,

What happens to video files when I export a project as an archive with optimized medias ?
Are the video files cut and encoded/compressed or just cut ?

Hello sebnoumea

When you archive your project, either with trimmed or with full media, you will be copying the media to a different location. There is no extra compression or re-encoding.
You will also archive a copy of the project file. The archived project file will connect to the archived media.

When you restore a project, the archived media will be placed into the User Media folder in the LumaFusion app. This means that the media is not available or viewable in the Photos app.

Does this answer your question?

regards

Hi Androu,

In fact what I really wanted to know is if the archiving process implies loss in quality for the video files.
You say there’s no loss even when the video files are cut when choosing the optimized option for archiving. That’s good news !
The reason why this is important for me is because since there’s no proper noise/flickering reduction option for videos on iOS, my workflow for now is :
1- edit in LumaFusion
2- export the project to Mac and extract the video files from the project archive
3- use FCPX and neat video plugin for noise/flickering reduction and color correction/grading and the exported media
4- import the video files back to LumaFusion and reconcile the optimized media manually

That’s a lot of work but I prefer working on my iPad.
Steps 2 to 4 should be easier when you bring us the Mac software.
Ideally all of this should be done in LumaFusion but even though I think color correction/grading could be done on iOS, i won’t hold my breath for proper noise/flickering reduction, on par with neat video, on iOS anytime soon. That’s unfortunate.

If anyone has a better workflow let me know !

PS : Androu, i’ve already talked to you about my difficulties to archive a project, send it on my Mac, process the video and my wish to be able the rebuild the project archive on the Mac so that I can simply send it back to LumaFusion. Is it something I can expect in the next 1.4 release ?

Hi sebnoumea,
Original video clips and they after processing can generate different perceptions during final editing. Even aesthetically.

Therefore, a more correct practice for me is to pre-clean and correct the original fragments before placing them in LF, because the application does not yet have enough tools to bring part of the clips to the desired condition. I'm waiting for version 1.4 and the already mentioned 1.5 (video improvements).

Often you have to use Deshake and more advanced light-color correction in VideoGrade; to clean up the original fragments of sound in Denoise, etc.

Either way, this is an iterative process. And in pleasure.

Hi Lumaluke,

Thanks for your input.
The problem for me is that noise reduction processing is really resources intensive and time consuming in Neat Video.
That's why I prefer do the cut and then process the final edit later (typically only a few minutes instead of potential hours of footages). If I would do as you suggest, it would take me hours and hours of noise processing before I can start the edit process. Plus, I have profiles for noise reduction that are meant to be used on raw footages straight out of my camera. If I apply color correction/grading first, the profiles won't work as good. That's why it is a best practice to always apply the noise reduction effect in any NLE software, BEFORE any other effect like color correction/grading. In practice you may color correct/grade first but when exporting the movie the noise reduction would be applied first.

I will investigate further and I hope Lumafusion will help in my process

Cheers

Not at all. Any normal grading application can connect Neat Video as a plug-in. Selecting only the desired region and applying pre-saved profiles, we do not waste time processing unwanted fragments and parts.
That's the way it's done . And then the finished fragments are sent to LF.
Somehow it's all about the workflow.

IMO, the hardware power and capacity of the mobile platform, as much as I would like it, are not yet sufficient for complex works. Therefore, in choosing your own mobile / stationary balance, so much attention is paid to achieving the maximum primary quality of the source material. But the reality so far successfully defeats these mobile attempts. That's why I'm so skeptical about the efforts of people on the stage trying to convince smiles and waving hands to talk about the sunset era of computers. This is a long process of tug-of-war. This is felt not only in the processes of video processing, but also in composing music. Although for light works like creating concepts, writing texts and surfing, I no longer use a computer.
That's why, in my opinion, it's so important to develop professional applications with a predictive interface on the mobile platform, and not primitive low-quality attempts to "cut down money".

LumaTouch has already done a lot and is moving in a powerful right way!

Thanks for all the great feedback. We definitely have a goal of making as many professional workflows as possible available on mobile platforms. But we also recognize that mobile hardware will likely never match desktop (though it's amazing how far it's come), and the closed sandbox environment won't allow for the type of wide plugin community that's available on desktop, so our second goal is to make it as painless as possible to bridge mobile and desktop, and we will be bringing out more features (and products) to accommodate that.

We are planning XML export in project archiving for FCP and Premiere as part of 1.5 (this may be made available a small additional in-app purchase), and while plans can change, this one is now at the top of our priority list and a part of our overall product plans, so it is coming soon.

Thanks to both of you for your responses.
I’ve lost my (long) reply so I’ll try one more time (iOS 11 still in beta !)...

I agree with you that mobile platforms are not quite at the level of the desktop PC... yet ! Have a read at this article : http://bgr.com/2017/06/15/2017-ipad-pro ... omparison/ (CPU, little advantage Mac; GPU, advantage iPad Pro).
The iPad Pro/iPhone and iOS combination is getting closer and closer to the desktop world in terms of power and software. And this is where Apple really shines when it comes to optimizing hardware and software together. This is the main reason why we usually see pro apps come to iOS, at least first if not only exclusively on iOS.
I think it is now only a matter of good software. And we’re getting there thanks to apps like LumaFusion or Affinity photo, which is another great example of pro software on iOS (it’s current implementation is almost on par with its Mac OS version). iOS has made great progress too. Look at h265 support, AR, metal2 just to name a few.
Still, iOS has some ground for improvement too, especially if we consider the sandbox and the difficulty to adapt a plugin ecosystem, as we know it on the PC, to iOS. I'm hopeful some good solutions will come from Apple and/or third party devs. Look at Audiobus which has en ecosystem of more than 900 compatible apps ! This concept is really interesting but I don’t know how it would translate to video. Nonetheless, I think something likewise should be investigated.

It’s reassuring to see devs like Luma who understand this transition and help advanced/pro users live that mobile life with its current limitations. I can’t wait to use/test the forthcoming desktop integration, especially with FCPX. My aim is to do the most on my iPad and use my Mac only for the current limitation of iOS/LumaFusion which are, for now, color correction/grading and noise reduction.
And who knows, maybe be in a couple of year, thanks to the progress in codecs (better compression, less noise, smaller files), the improvement of video hardware (support for better codecs, again less noise and better image quality at an affordable price) and software (iOS, Luma and others), we will have an acceptable level of quality on mobile platforms with good workflows. The needs of prosumers and advanced users could be covered for their most common usages.

@cdemiris99, do you have open slots for beta testing your iOS and Mac OS software ? I would be interested to contribute and help shape the future of LumaFusion.

Can you export an ‘Archive Project’ to GoogleDrive?
Don’t see it there. Still new to the program. Thanks.

How do you extract the video files from a .spryzip file?
