I’ve been trying to create AI videos for a project, but I keep running into confusing tools, poor video quality, and unclear steps. I need help understanding the best AI video generators, how to write prompts, and what workflow actually works for beginners.
Start with one tool, not five. Most people get bad results because they stack random apps and lose quality.
Best picks:
Runway, best for text to video and image to video. Fast. Good UI.
Pika, easy for short stylized clips.
Luma Dream Machine, strong motion and camera feel.
Synthesia or HeyGen, best for talking avatar videos.
CapCut or Premiere, for editing after generation.
Simple workflow:
- Write a 1 sentence scene.
- Add subject, action, camera, lighting, style.
- Keep clips 3 to 8 seconds.
- Generate many takes.
- Upscale only the winners.
- Edit all clips in one timeline.
Prompt format:
Subject. Action. Setting. Camera move. Lighting. Style. Duration.
Example:
“A woman in a red raincoat walking through a neon Tokyo alley at night, slow dolly in, wet pavement reflections, cinematic lighting, realistic style, 5 seconds.”
If faces drift, use image to video with a ref image.
If motion looks weird, ask for one action only.
If quality looks soft, render at highest native res first, then upscale.
If lip sync matters, use avatar tools, not raw video gen.
Big tip. AI video works best when you think like an editor, not a prompt wizard. Generate short. Cut tight. Hide the bad bits. Thats the part most pepole skip.
Biggest thing nobody tells you: “best AI video tool” depends on the type of video, not the hype. I mostly disagree with the idea that you should always start with one tool only. Sometimes that actually slows you down, becuase each tool has a lane.
My rough split:
- cinematic b-roll: Runway, Luma
- weird/stylized social clips: Pika
- talking presenter/training vids: Synthesia, HeyGen
- fast editing, captions, cleanup: CapCut
- serious finishing: Premiere, Resolve
Where people mess up:
- They ask for too much in one prompt
- They expect 20-second perfect shots
- They generate before planning transitions
- They upscale trash footage and wonder why it still looks bad lol
Prompting tip: write it like a shot list, not a novel.
Bad:
“Create an amazing futuristic video with emotion and awesome vibes”
Better:
“Medium shot of a tired doctor in a crowded hospital corridor, looking at flickering monitors, handheld camera, cold fluorescent light, realistic, shallow depth of field”
Also, negative prompting matters in some tools:
“no extra fingers, no face distortion, no text, no watermark, no frame flicker”
One thing @suenodelbosque didn’t really get into is consistency. If your character changes every clip, your project falls apart fast. Use reference images, seed settings if the tool offers them, and keep wardrobe/background descriptions identical.
If you want cleaner results, build in this order:
script > storyboard > style frames > test clips > final clips > edit > sound design
Honestly, sound fixes more “bad AI video” than people admit. A mediocre clip with solid SFX/music feels way more proffesional than a pretty silent one.
