LumaFusion 1.7 is now available in the App Store. This update includes great new features like search and sort in the library, soft edges and curved corners in cropping, and our new integration with Storyblocks, a great royalty-free library of video, audio and sound effects. A sample of clips are included free, with a low-cost subscription available in-app for access to the full library

Hi every body, hoping someone could help...

The problem is that when I edit a project with multiple audio track the Luma Fusion make some bad joke: one (ore more) audio track mute, other track "stop and go", wrong volume level, bad sounds and so on....

This only happen in EDITING, no problem at all in the EXPORTED file, but is quite annoying... I have to switch from Luma Fusion to the iOs and then to Luma Fusion again to resolve the problem...

I use video track from Go Pro (and detach the audio for editing) and other video track form iPhone 7 (with Filmic Pro). NB: when I detach the audio from iPhone track the audio file extension is IPCM

IPad Pro 12.9 (latest model), latest Luma Fusion version (1.6.6).... very speed, very exciting with Luma Fusion (beautiful result) but with this trouble in editing...

Thank you all

I can +1 for this one. I have also had problems with all the audio tracks not playing when resuming playback from the edit. Backing up the play head and restarting the playback usually gets around the problem. Also no issues with rendering.

Normally, it’s not a problem, but towards the end of the project when some of the volumes of clips weren’t staying set, it could cause you to go looking for the trouble in the clips, when the problem was in the playback. Time waster.

One detail I can add is that the problem became worse when I took a timeline and started replacing the low-bitrate 720 proxy footage with high bitrate 1080 footage. Maybe the harder Luma has to work, the more likely it is to have the problem.

I work on a 10.5” iPad Pro.
