- Opening Movie Maker redirects to the Photos app, with a note that Microsoft Clipchamp has this functionality now and Movie Maker is deprecated.
- Install Clipchamp and see that its hilariously bad at batch-adding clips to the timeline. Adding 300 clips, one at a time, is a dealbreaker.
- Look up reviews for free 3rd party apps to do this on Windows. Find everyone recommending DaVinci Resolve. Fine. Install Resolve. Looks great. Import my clips, and get only audio. A quick Google search tells me that Resolve free version doesn't support importing 10-bit video. Welp.
- Let's try FOSS then. Shotcut is supposedly better than Openshot. Install Shotcut. Import all clips, add to timeline and export. Takes a few hours to export, displays a Success message and gives me the first few seconds of video, followed by a couple of hours of just audio.
- F** it, let's try Openshot. Hesitant because I've heard a lot of crashing happens, but what do I have to lose. Install. Import clips. Add to timeline. Let's me add transitions. Export takes a few hours. Gives me flawless output file.
Moral of the story: For occasional amateur video editing, Openshot is great.
