Today I did a screen capture on what I'm talking about with the painstakingly slow writing of the bloated spryzip files.
A 1:47 video took 2 hours and 39 mins to write and upload to a 64GB Sandisk iXpand drive. It also took 55% of the iPad's power, and 59GB of the Sandisk's space.
Things of note:
iOS Version: 12.3.1
LF Version: 22.214.171.1244
iPad Pro 10.5" 256GB Memory
Video Length: 1:46:24
Exporting the FULL backup with original media says it would take 15.62 GB
Exporting the trimmed version says it will take 1.19 GB
Following through and writing the project does not give any indication of how long it will take, nor how big the final file is. We are to assume it would be 1.19 GB.
After 46 mins of waiting, LF starts to write a 59GB file to iXpand!
It took the iPad from 55% power down to 7% power.
A message at the end states that the Project upload is complete, but that 8 media items failed to export (this is not good).
This is very inefficient. Not only does this render my iPad unproductive for almost 3 hours, I then have to be tethered to a power source for another 2-3 hours until it is fully charged. Like I stated earlier, the time I save using LumaFusion over another editing platform is more than offset by the time it takes to back up my video project.
If you want to use this as a production platform, it has a ways to go. I was so hoping.
Here is a link to a condensed video of my screen capture: https://youtu.be/kkWNfxbNNNA
I have five, 2 min. video projects that I need to back up and get off my iPad to make room for more. I deleted my 46 min. video project because I did not have enough space on my Sandisk iXpand drive, and the iPad ran out of power before it would finish writing to the drive.
Note: the Lightning port is occupied by the Sandisk drive, so you cannot charge the iPad while LF is backing up to the drive.
