Perfect! – Slow Fast Slow - Control the Speed of Your Videos Review

I tried half a dozen different apps to speed up some time lapse videos and this was the only one that worked flawlessly, without glitches, ransom or persistent ads. SPEED PRO seemed like a contender but being hit with 10 ads within 30 sec was a nightmare! Others couldn't import/export in ORIGINAL FORMAT which is crucial if you're working in iOS. I like their business model, which involved perusing thru other other apps they make briefly at launch. I can live with it as long as I know what to anticipate.
