Hi, there may have been a miscommunication about this issue here at Luma Touch. This isn't a known issue. We have had a known issue with some FiLMiC clips reporting wrong frame rates, but that should be fixed in 1.7.4. I think what you're seeing here is something else. When you airdrop the clip to the iPad, it's going to store it in Photos and may be doing some type of conversion on the transfer. One thing you could try is to start a quick project on the iPhone in LumaFusion (making sure the frame rates are correct), then airdrop the Project Archive to the iPad which will open in LumaFusion and the frame rates should remain correct.

If you do have clips that are showing the wrong frame rate, and can send a link where we can download them to support@luma-touch.com, I'll take a look and see if I can determine why this happening.

Thanks.
Hi Chris,

So I did a quick test following your instructions. I made a new project adding both old and new clips shot at 4k 60fps on my iPhone 8 Plus, imported to LumaFusion via Filmic Pro (not ios Photo). Once imported, the clips are indeed still showing at 66.67fps, although a couple clip did came out right at 60fps but they were all shot in the same setting which is odd. As I mentioned, this frame issue didn’t happened in my iPhone before, but now I notice it every since I updated LumaFusion to 1.7.4, but that’s just my guess.

Next, I then airdropped the project archive to my iPad and the results are the same, the clips that were 66.67fps on my iPhone remained at 66.67fps. So this leads me to believe it is not necessarily the IOS Photo app that is causing this.

I will email this video to you for your reference, thanks.

Quick update, it has something to do with the Camera Format setting and happens also Airdrop is not involved.

As I mentioned in my previous post, I’m using the stock camera in my iPhone X, which is set to 4K at 30fps and High Efficiency (hvc1).

I changed the Camera Format settings from High Efficiency to Most Compatible leaving the rest unchanged and all new videos were now identified as 30 FPS. Videos that previously show 31.58 FPS still show the incorrect value.

Then I changed the settings back to High Efficiency and filmed a video. This new video is identified as 31.58 FPS again. The video filmed when the format was changed to Most Compatible still shows as 30 FPS, even after removing it an adding it again.

I’m not sure if LumaFusion actually speeds up 31.58 FPS videos. It is just a 5% difference.

I hope this gets resolved soon.

Hello,

It's not limited to Filmic Pro footages, I have exactly the same issue with my drone. And it's independant from AirDrop. Nota: results have changed with the last revision 1.7.5 (previously 4K 30 was 31.58, now it's 29.97). Hereafter my tests:
Source --> LumaFusion
4K 24 FPS --> 23.98 FPS
4K 25 FPS --> 25 FPS
4K 30 FPS --> 29.97 FPS
1080p 24 FPS --> 24 FPS
1080p 25 FPS --> 26.09 FPS
1080p 30 FPS --> 30 FPS

Not sure it has really an impact on the movie, seems to be only a UI issue.
Hope this help.

We are working on this issue for an upcoming update. Please note that it should not impact editing in any way, just the display of the frame rate in the info panel.

Looks like this is still happening in 2.4.1

In my case I am recording with 48 FPS 10-bit HVEC w/ 48 kHz PCM audio on an iPhone 12 Pro and it's showing up as 50 FPS... sometimes it reports as 46.15 FPS for shorter clips...

I also noticed that you need to be careful not to airdrop via the Photos app without ensuring that you select the photos app transfer setting to retain original format (otherwise the Photos app transcodes the footage for you into some other format - in my case losing the 10-bit and changing audio to 44.1 kHz).

I should add that I just copied these clips from my iPad to my desktop system (Windows 10, Resolve Studio 17b6) and Resolve reports the clips as 46 FPS as well (on the clips LumaFusion reported as 46.15) so my guess is the issue is not specifically LumaFusion's (unless Resolve and LumaFusion both have the same bug, lol).

So I don't know if the bug is in FILMIC Pro or whether this is something to do with the HVEC codec and iPhone 12 Pro's use of variable framerate... Very odd.

Anyone else have any ideas?

Thanks

Steve

Add - I've since done some research and found that this is not a LumaFusion thing (in fact, LumaFusion does the right thing by correctly interpreting the variable framerate from the iPhone). This article explains it:

https://www.provideocoalition.com/filmi ... -nab-2019/

I will need to perform a lengthy recording to check for audio sync in both LumaFusion and in DaVinci Resolve and Avid Media Composer (my two desktop NLEs of choice) to see how this plays-out.

Cheers
