AI Tools for Video Creation: What I Use for Reels, Voiceovers and Explainers

There are hundreds of AI video tools, and new ones appear every week. The easiest way to choose is by job: what part of the video do you need help with? This guide groups the tools that way and tells you honestly what I use and what I learned.

I make short reels for Veloxis with a mix of code-based templates, an Indian-language AI voice and stock footage, and I have tested open-source video models on my own PC.

The five jobs in a video

Avatar tools such as HeyGen combine jobs 2 and 3: a talking presenter from text.

Script: start here

A video is only as good as its first three seconds and its one main point. Before any video tool, write:

• The hook: one line that makes the right person stop.
• The single idea: what should they remember?
• The ask: what should they do next?

I draft scripts with Claude and then read them aloud. Anything that sounds like an essay gets cut.

AI video generators

Generators turn a text prompt or an image into a short clip. They are good for b-roll (background shots), product scenes and mood clips. They are weaker at exact text on screen, hands and faces that must stay consistent across shots.

Tips:

• Describe the shot like a camera operator: subject, action, camera movement, light, style.
• Generate several short clips and pick the best, rather than one long one.
• Most generators give free credits or a free plan with limits; compare two or three with the same prompt.

Running models yourself: open models such as Wan can run locally in ComfyUI. I tried this on my PC: a 3-second clip took about 12 minutes. It costs nothing per clip, but it needs a strong graphics card and time.

AI voiceover

A clear voice matters more than fancy visuals. For English, many tools sound natural now. For Hindi and other Indian languages, I use Sarvam AI.

The lesson that saved me the most re-renders: listen to every line before publishing. Brand names, English words inside Hindi sentences, and numbers are where AI voices slip. I keep a small list of tricky words and spell them the way they should sound.

Editing and captions

• CapCut: fast for reels, auto-captions, templates.
• Canva: simple editing plus your brand colours and fonts.
• Descript: edit video by editing the transcript.

Always add captions; many people watch without sound.

Video as code: one template, many videos

If you make the same kind of video often, such as a weekly tip, a property listing or a quote card, code-based video saves hours:

• Remotion: write a video template in React, then render many versions from a list of data. My reels for Veloxis are built this way. Check its licence terms if you use it in a company.
• HyperFrames (by HeyGen): an open-source framework where the video is written as HTML, built so AI agents can create and edit videos.

You describe the design once; every new video is just new text, images and voice.

My simple workflow for a 30-second reel

1. Write the script with Claude, then cut it to about 70 words.
2. Make the voiceover (Sarvam AI for Hindi, English tools for English).
3. Pick b-roll: stock footage, my own clips, or a few generated clips.
4. Assemble in a Remotion template, or in CapCut for a one-off.
5. Add captions and a cover, check every word, then publish.

Rules I follow

• No fake people or fake results. Never make an avatar or a voice of a real person without permission.
• Label realistic AI content where the platform asks you to.
• Check facts in the script. AI tools can sound confident and still be wrong.
• Keep your own footage in the mix. Real places and real faces build trust.
