15 common video editing mistakes and how to fix them

Most amateur-looking videos share the same handful of problems — and almost all of them are quick to fix once you know what to look for. Run through this list before you export, and your videos will immediately look and feel more professional.

Story and pacing

1. A slow start

Problem: intros, greetings and setup before anything interesting happens. Fix: open on the most interesting moment or a clear promise. Move introductions later, or cut them.

2. Keeping everything

Problem: every good-ish shot makes the cut, so the video drags. Fix: ask of each clip, "would anyone miss this?" If not, remove it. See our trimming guide.

3. Dead air

Problem: pauses, "um"s and silences between sentences. Fix: split around them and delete the gaps, leaving a few frames of breath.

4. No clear point

Problem: the video covers several ideas and lands none. Fix: one video, one idea. Save the rest for another video.

Sound

5. Music drowning speech

Problem: viewers strain to hear the words. Fix: lower the music well below speech, or let it duck automatically under voiceovers. See our music guide.

6. Uneven volume

Problem: one clip is much louder or quieter than the next. Fix: set each clip's volume so the level stays consistent, and check the whole video with headphones and on a phone speaker.

7. Echoey or noisy audio

Problem: recorded in a big, hard room or far from the mic. Fix: re-record narration in a soft room close to the mic. See our voiceover guide.

Visuals

8. Too many transitions and effects

Problem: a different effect on every cut. Fix: use straight cuts by default and one transition style for scene changes. See our transitions guide.

9. Mismatched colour

Problem: clips from different cameras or times of day jump in colour and brightness. Fix: adjust brightness, contrast and saturation per clip, then apply one consistent look. See our colour guide.

10. Shaky footage

Problem: handheld wobble makes everything look amateur. Fix: use the steadiest takes, keep shaky shots short, and film with support next time. See our phone filming guide.

11. Choppy slow motion

Problem: 30 fps footage slowed down stutters. Fix: keep slow motion above about half speed for normal footage, and shoot at 60–120 fps when you plan to slow it down. See our slow motion guide.

Text and graphics

12. Unreadable text

Problem: small text, low contrast, fancy fonts or text that vanishes too fast. Fix: bigger bold text with an outline or box, on screen long enough to read twice. See our text guide.

13. Text under app buttons

Problem: captions hidden by TikTok or Reels interface elements. Fix: keep text away from the bottom and right edges on vertical video.

Format and export

14. The wrong shape

Problem: a horizontal video posted to a vertical platform, with black bars or awkward crops. Fix: set the canvas to the platform's shape before exporting. See the size cheat sheet.

15. Not watching the final export

Problem: typos, black frames or audio glitches only noticed after posting. Fix: always watch the exported file all the way through — ideally on a phone — before you share it.

Pre-export checklist

  • Does the first second earn attention?
  • Is every clip necessary, and every pause removed?
  • Is speech clear and are levels consistent?
  • Is there one consistent look, with effects used sparingly?
  • Is all text readable at phone size and clear of app buttons?
  • Is the video the right shape for where it's going?
  • Do you have the rights to all music and footage?
