Video

“Generate, edit and clip video with AI.”
1 of 2

AI video splits into three jobs, and few tools do all of them. For generated shots, Veo adds its own sound and dialogue from £4.49 a month, Kling is known for realistic human movement and has a free plan, and Runway adds editing and effects. HeyGen and Synthesia turn a script into a presenter video with an AI avatar. Descript edits footage you already have by editing its transcript, and cuts clips for social.

Questions

What people ask about video.

Which AI video tool suits a product ad on a small budget?

Kling has a free plan and is known for realistic people at a low price, a good fit for lifestyle shots. Veo starts at £4.49 a month and generates clips with built-in sound and dialogue. Luma Dream Machine, from $25 a month, gives smooth cinematic motion and lets you guide shots with keyframes. Try your own product image as the starting frame in two of them.

HeyGen or Synthesia for training videos in several languages?

Synthesia presents your script with an AI avatar in over 140 languages, and you edit the text to re-render a video later. That suits teams that update onboarding and training material. HeyGen also builds avatar videos, can make a digital twin of you, and translates an existing video with the voice synced to the lips. Pick HeyGen for your own face, Synthesia for libraries of training content.

Can I make a whole video from scratch with AI, or only short clips?

Generators such as Veo, Runway, Kling, Higgsfield and Luma produce short clips, and Kling and Luma can extend a clip once it is made. A finished video still needs those shots assembled, with a voice-over and captions. Descript handles that assembly through its transcript editor and also records and cuts clips for social media. Plan your story as a list of shots before you generate anything.

Is Descript enough if I film myself and only need editing?

For talking-head and podcast-style videos, often yes. Descript turns your recording into a transcript, so deleting a sentence deletes it from the video. It removes filler words, clones your voice for fixes and has a free plan. You need a generator only when you want shots you cannot film.

Do I need to label AI-generated video when I post it?

The EU AI Act requires you to disclose realistic AI video that could pass as real footage, such as deepfakes. Avatar videos from HeyGen or Synthesia count, so say clearly that the presenter is AI. Platforms like Instagram, TikTok and YouTube also ask you to tag realistic AI content. A short line in the caption covers most cases.
