# Time Required for AI Video Creation Process
Published: October 16, 2025 · Author: Hitesh Kumawat
How long does it take to make a video with AI? A single AI-generated clip renders in seconds to minutes: Google documents 11 seconds to 6 minutes per Veo clip. A finished 1 to 2 minute video, with script, voiceover, visuals and editing, usually takes from under an hour to a few hours of your time.
*Last updated: October 6, 2026. Render times below come from each vendor's own documentation, checked on that date.*
The render is rarely the slow part. Most of the time goes into writing, reviewing, regenerating and editing. This guide breaks the AI video creation time down by stage, shows the render times vendors publish, and explains how much of the total is voiceover.
Quick answer
Seconds to minutes to render, but hours of your time. A single AI clip renders in 11 seconds to 6 minutes (Google Veo 3.1). A finished 1 to 2 minute video usually takes under an hour to a few hours of your own time, because writing, regenerating and editing take longer than rendering. Use the estimator below to size your own project.
Key Takeaways
✓Short clips: Google's Veo 3.1 documentation lists latency of 11 seconds to 6 minutes per clip, for clips of 4, 6 or 8 seconds.
✓Avatar videos: HeyGen says 1 minute of avatar video usually takes about 10 minutes to generate. Translation takes about 5 minutes per minute of content.
✓Script-to-video tools: Pictory's FAQ says a first video might take about an hour, dropping to about 15 minutes once you know the tool.
✓Your time matters more than render time. Scripting, review and editing usually take longer than generation.
✓Voiceover is one of the quickest stages with AI. You generate narration from the script and fix single lines, instead of booking a recording session.
## Time to make an AI video
It depends on what kind of video you're making. The table gives realistic ranges for common formats. Rows marked "documented" come from vendor docs; the rest are our planning estimates for a person doing the work.
Video type
Typical time
Source

11 seconds to 6 minutes to render for a 4, 6 or 8 second Veo 3.1 clip (Google docs). Peak hours are the slow end, and you will often regenerate.
About 10 minutes to generate, often faster (HeyGen help center). Time of day, resolution and plan tier all change it.
About 5 minutes per minute of content (HeyGen help center).
About 1 hour at first, about 15 minutes with practice (Pictory FAQ).
1 to 3 hours of your time (our planning estimate) for the script, an AI voiceover, visuals, editing and captions.
2 to 5 hours of your time (our planning estimate) with an AI voiceover and screen recordings.
## AI video generation time
AI video generation itself takes seconds to minutes per clip or per minute of video. Vendors publish these figures in their docs, and they all say busy periods slow things down.
Tool
What the vendor says about generation time
What affects it
Google Veo 3.1 (Gemini API)
Latency of 11 seconds minimum, 6 minutes maximum during peak hours
Peak hours, resolution, clip length
HeyGen avatar videos
About 10 minutes per 1 minute of video, often much faster
Time of day, resolution, plan tier, avatar and voice engine
HeyGen video translation
About 5 minutes per 1 minute of content
Same factors as above
Synthesia
No fixed time; videos move through stages such as Queued, Preparing and Rendering
Longer videos and busy periods take longer
OpenAI Sora 2 (API)
A single render "may take several minutes"; the API was shut down on September 24, 2026
Model, API load, resolution
HeyGen notes that Monday mornings (US Eastern time) are its busiest period, and that higher plan tiers get priority. Synthesia asks users not to generate the same video several times, because that increases wait times.
## Duration and format limits
Text-to-video models make short clips, not finished videos. Google's Veo 3.1 generates clips of 4, 6 or 8 seconds at 24 frames per second, in 720p, 1080p or 4K (1080p and 4K at 8 seconds only). Audio is generated with the video.
OpenAI's Sora 2 API supported 16- and 20-second generations before it was shut down on September 24, 2026. If you followed older guides that recommended it, plan around a different model.
Avatar tools work differently. They generate a presenter speaking your script, so length is set by the script and your plan. HeyGen's free plan, for example, allows videos up to 1 minute. For longer pieces, you assemble many clips or scenes in an editor.
## Creation time by stage
Most AI videos go through the same 6 stages. These are planning estimates for a 60 to 90 second video made by someone familiar with their tools.
1. **Script: 15 to 45 minutes.** An AI writing tool can produce a draft quickly. You still need to check facts, cut it to length and make it sound spoken.
2. **Voiceover: 10 to 20 minutes.** Generate the narration, listen once, and fix mispronounced names or rushed lines.
3. **Visuals: 20 minutes to 2 hours.** This is the most variable stage. Text-to-video clips often need several attempts; stock footage and screen recordings are faster.
4. **Editing: 20 to 60 minutes.** Cut visuals to the voiceover, add captions and music, and fix transitions the AI got wrong.
5. **Render and export: a few minutes.** Depends on the tool, resolution and queue.
6. **Final review: 10 to 15 minutes.** Watch it once with sound and once without, as many viewers will.
Regeneration is where projects run long. Each text-to-video attempt costs render time and credits, so a clear prompt and a locked script save the most time.
Estimate your own AI video time
Untick the stages you can skip, then pick your experience. The ranges are this guide's planning estimates for a 60 to 90 second video; the beginner multiplier follows the "2 to 3 times longer" rule of thumb below.
Two quick answers
Show me a worked example
Add the low ends: 15 + 10 + 20 + 20 + 10 = 75 minutes. Add the high ends: 45 + 20 + 120 + 60 + 15 = 260 minutes, about 4 hours 20 minutes. Render and export add a few minutes. That is why the same 60 to 90 second video can take just over an hour for one person and most of an afternoon for another.
Show me why my job is slow
HeyGen says Monday mornings (US Eastern time) are its busiest period and that higher plan tiers get priority. Synthesia says videos move through stages such as Queued, Preparing and Rendering, and asks you not to generate the same video several times. Google lists up to 6 minutes per Veo clip during peak hours.
Visuals are the most variable stage, while an AI voiceover is one of the shortest steps in a 60 to 90 second video.
## Voiceover share of time
With AI, voiceover is usually one of the shortest stages. Without it, it's often one of the longest. Our [AI voiceover guide for video producers](https://kveeky.com/blog/ai-voiceover-for-video) covers the full voice workflow.
How it works in Kveeky: paste a script, pick a voice, download the audio.
A human voiceover means casting, booking a session, recording, and waiting for files. Every script change after that means a new session. With an AI voice, you paste the script, pick a voice, generate the audio and replace single lines when the script changes.
Here's how that works in [Kveeky](https://kveeky.com/):
1. Paste the script and choose from 700+ voices across 40+ languages.
2. Set speed and volume, and pick an emotion (Neutral, Happy, Love, Angry, Calm or Sad) for the hook.
3. Generate, listen, and regenerate only the lines that need fixing.
4. Download the audio and drop it on your timeline.
How long is your voiceover, and does it fit the free plan?
Enter the words in your script. Speaking pace is 150 words a minute and the free plan is 500 credits, about 40 seconds, a month. Use it to cut your video to the voice.
The whole voice step in one screen: paste the script in the box, choose a voice, adjust Speed, Volume or Emotion in Settings, press Generate speech, then download the audio. Only the lines that changed need to be generated again.
Locking the voiceover early speeds up everything after it. Editors can cut visuals to a fixed audio track instead of guessing at pacing. Kveeky's free plan gives 500 credits a month, about 40 seconds of audio, which covers several short social videos. For a full walk-through, see this [script-to-upload AI voiceover workflow in 30 minutes](https://kveeky.com/blog/ai-voiceover-workflow-30-minutes).
## Beginner average time
Expect your first AI video to take 2 to 3 times longer than later ones. You're learning the tool, testing prompts and figuring out what to fix.
Pictory's own FAQ gives a useful benchmark for script-to-video tools: about an hour for a first video, dropping to about 15 minutes with practice. Text-to-video models from a prompt or an image take longer to learn, because results vary more between attempts.
A sensible first project is a 30-second video: one short script, an AI voiceover and 4 to 6 clips or screen recordings. If you're still choosing tools, start with our list of [free AI video generation tools to try](https://kveeky.com/blog/free-ai-video-generation-tools-to-try). Doing many at once? The [lazy creator's guide to batch-producing 30 videos in a weekend](/blog/lazy-creators-guide-batch-producing-30-videos-weekend) shows how to share one script, voice and template across a series.
## Making AI videos faster
These habits cut the most time from an AI video workflow.
- **Lock the script before you generate anything.** Every script change ripples into voice, visuals and edit.
- **Generate the voiceover first.** Then create or trim visuals to match its timing.
- **Write specific prompts.** Name the subject, action, camera move and style. Vague prompts mean more regenerations.
- **Preview at low resolution.** Render the final version at full resolution only once.
- **Don't resubmit a slow job.** Duplicates can slow the queue further.
- **Reuse a template.** Keep the same intro, captions style and music bed across a series.
- **Avoid peak hours for big renders** where the vendor says its queue is busiest.
If you're choosing between a voice-only workflow and an avatar tool, our [HeyGen alternatives guide](https://kveeky.com/blog/heygen-alternatives-top-ai-tools) explains which is faster for which kind of video.

## Frequently asked questions
### How long does AI video generation take?
A single clip usually renders in seconds to a few minutes. Google's Veo 3.1 docs list 11 seconds to 6 minutes per clip. HeyGen says avatar videos take about 10 minutes per minute of video, often faster.
### How long does it take to make a video with AI for social media?
For a 30 to 60 second social video, plan on 1 to 3 hours the first few times. That covers the script, an AI voiceover, generating or finding visuals, editing and captions.
### Why is my AI video taking so long to generate?
Queues get busy at peak times, and higher resolutions and longer videos take longer. Some tools give higher plan tiers priority. Don't resubmit the same video, because duplicates can add to the wait.
### How long can AI-generated videos be?
Text-to-video models make short clips; Veo 3.1 makes clips of 4, 6 or 8 seconds. Avatar tools can make longer videos, with limits set by your plan. Longer videos are assembled from many clips in an editor.
### How long does an AI voiceover take for a video?
Plan on 10 to 20 minutes for a 1 to 2 minute voiceover, including choosing a voice, listening back and fixing a few lines. Script changes later only need the changed lines regenerated.
### How long does HeyGen take to translate a video?
HeyGen says translation takes about 5 minutes per minute of content, and busy periods can be slower.
### Does a paid plan make AI video generate faster?
Sometimes. HeyGen says higher plan tiers get priority in busy periods. Synthesia gives no fixed time and asks you not to resubmit the same video, because that adds to wait times.
### How long should I plan for my first AI video?
Expect your first video to take 2 to 3 times longer than later ones. Pictory's FAQ gives about an hour for a first script-to-video, dropping to about 15 minutes with practice.
### How many minutes of voiceover does the Kveeky free plan cover?
The free plan gives 500 credits a month, about 40 seconds of audio, with no credit card. That covers several short social videos.
### Should I make the voiceover before the visuals?
Yes. Lock the script, generate the voiceover first, then cut or trim visuals to its timing instead of guessing at pacing.
