Can LumaFusion version 3 edit directly from an SD card on an iPad Pro M1 2021?

Yes it can :)

Cheers,
Dave.

Good one. Thanks Dave. I’m a bit surprised it doesn’t work as smoothly for me using an Apple USB-C SD card reader

You're very welcome, Mark.

If it's the pause/latency you're talking about, without testing more I'd guess that LumaFusion will vary that latency depending on the resolution and frame rate of the project and media and where the media is being edited from, internal storage, external SSD, external SD etc. and how good/fast the storage medium and readers/drives are.

Interestingly, LumaFusion doesn't seem to pre-buffer where the play head is, only once you hit play. This is evident with the latency with playing after moving the play head. Once in play and you pause the next play command from the same paused position will have a lot less latency, as LumaFusion has already built a video buffer from the previous play but it's not as instant as other NLEs. Once any movements or changes have occurred it has to rebuild the buffer after the next play command and the latency once again increases.

I assume this buffering latency is just what LumaFusion does and it isn't being caused by iOS as the same happens on MacOS with LumaFusion and that's regardless of inter-frame or intra-frame sources.

I'll do a video at some point that does a basic explanation about the video buffer and specifically why LumaFusion does that pause after hitting play, it's on my list of things to do about LumaFusion. I have to be careful about how much time I spend on videos that don't get many views but I do have a list of things I'd like to show with LumaFusion.

That USB C hub that I use is quite an odd one. Aside from external USB SSD and USB C access, that hub is just as good as a Thunderbolt one. The SD card interface on that hub just happens to be a good one. I have tried many hubs and cables with the iPad Pros and the performance varies quite a bit. That hub is definitely the best I've used so far. I use it for iPad Pro game capture as it seems to fully support DP Alt Mode and gives a full height 4K/60 output.

How does your Apple USB C SD card reader respond?

Cheers,
Dave.

Thanks Dave. Editing short 4K clips from the SD card reader was useable but not exactly smooth. I don’t really need to do it this way because I bought the new iPad Pro to have enough memory to store another five years of my own videos on device. I make frequent journal type videos of travel and events in my life using clips copied via SD from iPhone, or off the SD from my Osmo action camera or a Nikon P950 for long zoom wildlife shots.
Since I currently have lots of spare memory I just copy everything from the SD cards into LumaFusion files before starting to edit and haven’t bothered working off an SD again. It probably also helps that when making videos that will seem a faithful record in five years time it’s best to avoid as many YouTube style editing effects as possible. I do use stabilisation a lot, colour correction to match scenes from different lighting and cameras, and I try to cut in as much audio from the occasion as possible. If there’s no audio I’ll use a music track and some synching. Usually not more than 3 timeline tracks.

Hi Mark.

Yes, having a lot of internal storage really helps. This is something that I’m having a problem with as I didn’t think I’d do any video on my iPad.

I’m just testing a few external SSD options at the moment to work out what is the most cost effective way for fast external storage. So far, the Samsung T7 1TB is working out quite well, although the USB/Thunderbolt interface on the iPad M1 isn’t as fast as the Mac M1s.

I’ll do a video about external SSD storage once I’ve worked out the best balance between speed, size and price.

Cheers,
Dave.

Had anyone considered an nvme drive in an enclosure? £70 for a 1TB WD Blue which as a bare drive is faster than the USBC 3.2 gen2 of the enclosure you'd be putting it in.

Any external SSD will work well. Although you won’t see much of an improvement compared to what is going on in this video with the SD card for this type of media. So NVMe won’t really make much difference for this type of media. LumaFusion and it’s frame/video buffer will become the limiting factor and bottleneck along with the iPad’s processing ability. There’s also the consideration of the USB C/Thunderbolt bandwidths on the iPads not being as fast as the actual standards allow for USB C and Thunderbolt.

For large space and convenience, the Samsung T7 drives are a great match.
