Expensive for what it does but Sony force us to buy it!
Unattended Sony A7IV powered down while recording, creating a 35GB black hole called an .RSV file where my footage should be. The size of the file made uploading to Restore.Media impractical and expensive ($90! And took all day). Wasted a lot of time with open source / Home Brew. In the end this app fixed a huge 4K file very quickly and cleanly. $110 is a lot for basically a fancy UI and some very basic stuff that Sony should be providing for free, but over time it will be a sound investment as this does occasionally happen on shoots with multiple cameras and just me operating. -1 star for the price gouging, but overall recommended.
