Explainer video length should follow the job the video does: 15 to 30 seconds for an ad, 60 to 90 seconds for a homepage or feature explainer, and one task per video for how-tos and training, usually under two minutes. Cost follows who makes it and how many you need. Videngine's published launch pricing works out at $7.90 an explainer at 10 a month and about $1 at 250.
Explainer video length by job
The right explainer video length is the shortest one that lets the viewer do the next thing, and that depends on why they are watching.
An ad viewer gives you seconds, a homepage visitor a minute or so, and someone following a how-to as long as the task takes.
| Job | Starting length | Narration budget | Why this length |
|---|---|---|---|
| Ad | 15 to 30 seconds, plus a 6-second bumper cut | About 35 to 70 words | The viewer did not ask for it. One problem, one claim, one action. |
| Homepage | 60 to 90 seconds | About 130 to 200 words | The visitor is deciding whether it is for them. Problem, how it works, one example, one next step. |
| Feature | 45 to 90 seconds | About 100 to 200 words | One feature, one outcome. If it needs a second outcome, that is a second video. |
| How-to | As long as one task, usually 30 seconds to 2 minutes | About 65 to 260 words | The viewer is following along and pausing. One task per video, so the title promises exactly what it shows. |
| Training | 1 to 2 minutes per task, as a series | About 130 to 260 words each | A module can run long; each video should not. Short parts are easier to find, rewatch and update. |
These are reasoned starting points, not survey averages. The narration budget assumes roughly 130 to 160 spoken words a minute, planned near the lower end, because screenshots and title cards need time on screen without a voice.
If an explainer will not fit, split it rather than speed it up. The explainer video maker guide lists more explainer types and the written sources each starts from.
Platform limits are ceilings, not targets
Platforms set maximum lengths, but none of them tells you how long your explainer should be. Three are worth knowing:
- YouTube Shorts: YouTube's help page on uploading Shorts says a Short can be up to 3 minutes long, with a square or vertical aspect ratio.
- Longer YouTube uploads: by default YouTube accepts videos up to 15 minutes long; a verified account can upload longer, up to 256 GB or 12 hours, whichever is less.
- YouTube ads: Google Ads lists bumper ads at 6 seconds and non-skippable in-stream ads at 15 to 60 seconds, by campaign subtype. Skippable in-stream ads have no maximum (under 3 minutes recommended), and viewers can skip after 5 seconds.
That five-second skip matters more than any ceiling: the opening has to say who the video is for and what it solves, because the viewer can leave at second five.
Limits change, so check the help pages before a campaign. Videngine typically gives each source a vertical 9:16 cut and a landscape 16:9 cut, so one script serves a Short and a homepage player.
What drives explainer video cost
Explainer video cost is set by who does the work and how many videos share it, far more than by the seconds.
Most of the work is deciding what to say and how it should look. Five things move the price:
- Script: finished words from you, or paid time for someone to learn your product and write them. Most revisions start here. How to write an explainer video script covers doing it yourself.
- Style: custom characters and hand-drawn whiteboard usually take the most hours per second, template motion graphics fewer, narration over screenshots and product images fewest.
- Voice: a hired artist, a synthetic voice or your own recording. Changing a line later means another session, a regeneration or a rerecord.
- Revisions: how many rounds are included, and when. A script change before animation is cheap; after it, scenes may be redone.
- Volume: the first video carries the set-up. Later videos that reuse it cost less, but only on a route built for reuse.
| Route | What you pay for | Where the cost grows | Fits best |
|---|---|---|---|
| Agency | A team: script, design, animation, voice, project management | Custom styles, extra rounds; each further video is largely new work | One flagship explainer carrying the brand |
| Freelancer | One person's time, often animation from your script | Scope beyond the brief; capacity for many | A few custom videos with a clear script |
| DIY tool | A subscription plus your own hours | Your time per video and keeping videos consistent | Occasional videos made in-house |
| Automated | A plan or per-video fee, after template set-up | Set-up first, then mostly review time | Many explainers from existing writing |

Videngine's prices for 10, 50 and 250 explainers
Videngine's plans include a set number of finished videos, so the cost per explainer falls as volume rises.
In US dollars, Starter is $79 a month for 50 videos, Growth $249 for 250 and Scale $599 for 750. Extra videos beyond the allowance cost $1.50, $1.00 or $0.80 each, by plan. A video is one finished render up to 2 minutes, and re-rendering the same video in the same month is free. Seats and brands are included.
| Explainers a month | Plan | Monthly cost | Per explainer |
|---|---|---|---|
| 10 | Starter | $79 | $7.90 |
| 50 | Starter | $79 | $1.58 |
| 250 | Growth | $249 | About $1.00 |
| 250, staying on Starter | Starter plus 200 extra videos at $1.50 | $379 | $1.52 |
At 10 a month you pay for capacity you do not use. At 250, Growth is $130 a month cheaper than Starter with extras.
Not on the invoice: your time approving scripts and reviewing each video before it goes out, which Videngine requires, and the one-off set-up of brand tokens (typefaces, colours, logo, motion). Free same-month re-renders mean a corrected line costs a review, not another video.
These are launch prices and Videngine is coming soon. Choosing a plan on the pricing page joins the launch list, with no charge today. There is no free plan.
A way to budget for explainer videos
Budget from a count of finished videos, not from a price per minute.
- List the jobs. Homepage, features, how-tos, training, ads. Note how many of each you need this year.
- Set a length for each from the table. Split anything over two minutes into a series, one video per part.
- Count deliverables. Multiply by formats (vertical, landscape) and versions, such as a short ad cut.
- Decide who writes the scripts. If you have help articles or feature pages, the words largely exist. If not, writing is your largest line.
- Choose the style, which chooses the route. Custom characters point to an agency or freelancer; narration over your own screenshots and images suits a tool.
- Price each route for the whole count. Ask what is included: revision rounds, voice, music licence, source files, the right to edit later. Check how tools count renders and formats.
- Add review time. Someone watches every video before it goes out, whoever made it.
- Pilot one before committing. Make one representative explainer, time the review, then multiply.
Step 3 is where budgets usually slip: 20 explainers in two formats is 40 deliverables, not 20.
When an agency is worth it
An agency is worth it when the explainer is a single, high-stakes piece whose story does not yet exist in writing.
That is often a launch homepage film, where the value is an outsider working out what the product is for. An agency or skilled freelancer is also the right call for character animation, whiteboard, presenters or live footage. Our guide to animated explainer styles compares the options; the explainer video guides cover each.
Videngine is the wrong tool for a bespoke brand film, character or whiteboard animation, or avatar presenters; for presenter videos a tool such as Synthesia fits better. It narrates in English only, it is not a timeline editor (a DIY editor suits hand editing better), and it is not available today.
It fits when your explainers already exist as writing: feature pages, help articles, release notes, procedures. Videngine reads the page or text, writes a script you can accept, edit or replace, records narration, captions it from the audio and renders an MP4 from coded templates for review. That is the AI explainer video route, where the 250-a-month arithmetic applies.
Questions about explainer video length and cost
How long should an explainer video be?
Long enough for the viewer to do the next thing, and no longer. Start with 15 to 30 seconds for an ad, 60 to 90 seconds for a homepage or feature explainer, and one task per video for how-tos and training. If it needs more than about two minutes, split it into a series.
How much does an explainer video cost?
It depends on who makes it and how many you need. Agencies and freelancers quote per project, driven by script, style, voice and revisions; tools charge a subscription or a fee per video. Videngine's launch pricing starts at $79 a month for 50 videos of up to 2 minutes each.
Why does explainer video pricing vary so much?
Because the routes sell different things: an agency sells a team's time on one custom piece, an automated tool sells reuse of a template across many videos. Compare them on the same count of approved videos.
Does a longer explainer video cost more?
Less than you might expect. For custom work, most of the cost of explainer video production is in the script, design and revisions, not the seconds. With Videngine, any finished render up to 2 minutes counts as one video.
How many explainer videos do I need before automation is worth it?
Automation pays when the same structure repeats, such as one video per feature or per help article. For one or two flagship films, a custom route usually makes more sense. Pilot one, time the review, then compare totals for your real count.
