BlitzCut's comparison article opens with a bold claim:
"In our tests, BlitzCut processes videos significantly faster than both TimeBolt and Recut."

Here's what they don't tell you: their "test" used a 15-minute video. Convenient, since their tool completely bricks on anything longer than 30 minutes.
We tested BlitzCut on a 59-minute, 58-second podcastβstandard length for professional content. The result? Frozen at 95% processing. No error message. No recovery option. Just stuck.
We tried three times. Same video. Same iPhone 16 Pro Max. Same result: bricked at 95%, three times in a row.
This isn't a bug. It's a platform limitation. BlitzCut runs on mobile processors. Professional video editingβ1-hour podcasts, 90-minute interviews, webinar recordingsβrequires processing power that smartphones simply don't have.
The Cherry-Picked Test
Their comparison article tests a 15-minute video. Why 15 minutes? Because that's safely under their failure threshold. Professional content runs 30-90 minutes. Podcasts average 45 minutes. Video interviews run 60+ minutes. Webinars can be 2 hours. BlitzCut cannot process any of this.
But there's another problem. Even when BlitzCut does work on short videos, look at the settings required to match TimeBolt's output:
On their 90-second short-form test, BlitzCut matched TimeBolt's 15-second output. Impressiveβuntil you see the settings. Minimum speech duration: 1.4 seconds.
This means BlitzCut cuts any phrase shorter than 1.4 seconds. It's not detecting filler words. It's just removing short pauses. In a real interview, this destroys your content:
"Yep" (0.4 seconds)βcut. "I know" (0.6 seconds)βcut. "Got it" (0.5 seconds)βcut. "Right" (0.3 seconds)βcut. "Makes sense" (0.8 seconds)βcut. "Exactly" (0.7 seconds)βcut.
These aren't filler words. They're responses, confirmations, natural conversation flow. BlitzCut removes them because they're short, not because they're fillers. This only "works" if every filler in your video happens to be perfectly isolated between full sentences. In real content, that never happens.
Meanwhile, TimeBolt's UmCheck uses AI to detect actual filler wordsβ"um," "uh," "like"βregardless of duration or position. No duration thresholds. No artificial hacks. Just AI-powered filler detection that works with production-ready settings.
Platform limitations make speed comparisons meaningless. BlitzCut is a mobile app for short-form social clips under 15 minutes. It cannot process professional-length content. Their comparison article deliberately tests 15-minute videos to hide this fundamental limitation. We tested 1-hour content. They failed three out of three times. Speed doesn't matter when you can't finish the job.
