I checked out cutstories. For mit does not work, because i can only choose 15 seconds for all parts. for my stories i need severals lengths of the segments. For exact timing. It would be great to get more export options in Luma Fusion.
It's a bit confusing what you are asking for/trying to accomplish.
Instagram Stories only let you upload 15 second segements at a single time - but there is no restriction as to how many segments you want to upload.
The way cutstory works, is that you simply upload any length of video to the app, and it chops the entire sequence into perfect 15 second bits, that flow perfectly one after the other. Then, you upload each 'cut' of 15 second chunks (that cutstory exports) up to Instagram stories.
What you end up with, is a perfect 'flowing' sequence inside instagram stories. It does not matter one bit, how you create your initial video - you don't need to be concerned at all about cuts or anything. Just make your video however you want, at whatever length. Then simply import the video into Cutstory and it will chop it up perfectly for you.
If the problem is that Cutstory chops things into 15 second bits, it does that PRECISELY because Instagram only lets you upload 15 second clips to instagram stories.
I'm not sure if you are completely familiar with how Instagram stories actually works, but if what you are trying to do is simply upload a long video to instagram stories and have it play in perfect sequence, trust me.....Cutstory does this....its exactly what is is designed for!
Believe instagram stories is my business. Belive me when a say that cut stories does not work for me, because sometimes i need 7 second- Clips sometimes 10, sometimes 15. Maybe you are not very professional in instagram stories and the power of exactly timed clips.
