Adjust clip playback speed

Speed the footwear clip to 1.5x so it matches the beat at 0:12 and keep the rest of the timeline at normal speed. Make sure audio pitch is preserved where possible and trim any resulting overhang so the cut to the slow-motion close-up at 0:15 is clean. Export a 16:9 MP4 for Facebook and a 9:16 vertical for TikTok.

Before I finalize the cut, make the pace obvious: speed the walking B-roll to 1.5x to hit the 0:12 beat, keep the hero close-up at 0.75x for emphasis, and label the sped sections so the reviewer can check sync with the guide track. Flag any motion blur or stutter that would make product details unreadable at higher speed.

I just sped a 10-second street B-roll to 1.5x to make the edit hit the beat, but now the background music and the natural cadence don't line up with the VO. The content lead, Marco, expects the VO to stay in sync and the client will notice any jitter. I’m not sure whether to nudge the speed, shift the clip, or retime the music. What likely caused the mismatch and what’s the best quick fix that keeps motion natural and VO intact?

Across several shorts I’ve overused speed ramps and now I spend hours fixing pitch shifts and VO sync. That delays reviews and makes me look careless to Marco and the creative director. Which editing habit should I adopt so speed changes reliably hit the music without breaking audio, and what simple checklist will stop me from introducing sync errors?
