R5: Unable to copy 4K 120fps files to iPad

[xt3tor5]

In my workflow for video files shot on the Canon R5 on the CFExpress card, I attach the USBC CFExpress card reader to the iPad, and insert the card from the camera. In the iPad Photos app, it shows up as a device and shows the thumbnails of the still and videos stored on the card. I can select a 4K video and import them into the Photos app and then use the standard Apple iMovie editor other 3rd party apps like Filmmaker Pro.

However, it shows an error exclamation mark and doesn’t import any 4K 120fps or 8K videos. I am able to import them to my iMac. I prefer the mobility of my iPad for short street or bird videos. I have tried CLog Off as well as CLog settings and the result is the same failure. I must be doing something incredibly stupid. Any solution appreciated. Thanks in advance 🙏

Have you looked at LumaFusion for the iPad?

Might not be possible.

Thanks, John for sharing that link. In that case, I have to wait until Apple provides support for them on AppleTV and iOS platform.

What codec are you using though for the footage?  On iPadOS/iOS, while there is iMovie and the Photos app, that's not going to work with every possible codec.

You typically need a non-linear editor such as Final Cut, Adobe Premiere, Davinci Resolve to work with those codes and then output to something that can work with Apple Devices.

For all my EOS C70 footage, I capture XF-AVC 10-bit 4:2:2 CLog2.  Either in All-I or Long-GOP.  Then, I import into Final Cut, edit, the export as-needed for web, Apple devices, etc.

Thanks, Ricky.

I am not sure about the codec in the 4K 120fps recording of R5. I think it is a10-bit 4:2:2 ALL-I (HEVC, H.265).

I explored Premier Rush and it is useless for this. I have now downloaded the 90 day trial version of FInal Cut Pro to experiment with it. I need to learn the basics of this tool now. It seems to load and play both the 8K 30fps  and the 4K 120fps videos on my iMac.

DaVinci Resolve has a free version that might fit your needs.

Thanks, John. I downloaded the free version of Resolve. Unfortunately, it can output to 1080p max. 4K and above is available in the paid version.

Is there a format of 4K 120fps that Apple devices would support? If yes, then transcoding to that could be the solution.

Thanks for the pointer, John.

Lumafusion is far cheaper than FCP (10% of FCP, no trial versions) and the interface is simple and superfast. It processed my 4K 120fps clips and was able to output 4K videos that my iPad, iPhone and Apple TV 4K could play. However, it has a severe shortfall when dealing with 8K. It can play it, but it outputs it to max 4K. 

I played with the FCP and it was able to do both 4K 120fps and 8K and output it while retaining the same resolution and the output files were reasonable compact and I could play them on iPad, iPhone and Apple TV 4K.

It will be nice to get an app on iPad that output 8K. Glad I started this thread as I am learning a lot.

Are you sure you even need to deliver 8K to iPads? That's rather pointless since the max possible resolution of an iPad (12.9 inch) is 2732 x 2048 which is less than 4K.

8K I believe is currently just an acquisition format and really not yet meant for delivery.  Especially not to mobile devices.
