In general, this app works mostly well except for a few error messages, when adjusting the font size for instance.
However, the biggest issue is, that it writs a .mov file that doesn’t conform to the AppSTore Preview guideline.
It looks as the video has much more FPS even though I selected 30 FPS in the export settings. The file is way larger as it needs to be.
Once converted with Final Cut Pro (which I wanted to prevent to use due to it’s odd UI) the resulting file was about 10 times smaller and worked with the AppStore.
I will contact the developers and will keep this review updated.
UPDATE:
The developers were very responsive and quick. However, even though they claim that the format is correct (they use the ProRes profile which is indeed one Apple claims to accept) Apple DOES NOT accept the Preview Movie generated by this app. Second, even if Apple would accept it, it is way too big. A 30 second movie will always be larger than the possible 500 MB if made for an iPad of iPhone 6 plus. So from this point, it is not possible with this app to generate Preview Movies.
Another issue just arose: I started maintaining the project files of the app on my Windows Server share. Once I did this, the app claims that I don’t have sufficient access rights, which is wrong. All my other files and even the big Final Cut project directories are on the same server and all can be opened and stored from my Macs without a problem. I did try SMB and CIFS just in case - without any difference. So I have to copy down the project files to the local HD in order to maintain them and then copy them back in order to get it working.
So I think this app needs some major improvemends and testing before it can be used. Definitely something I expected for this (too) high price.
