Product and service introduction videos 
Use a video you have made as the reference to create videos with different content for each product or model.
Show product photos as-is, one per scene, in order.
You can add a separately recorded screen recording to a video made from documents.
Choose horizontal 16:9 for product pages or vertical 9:16 for social media.
HOW IT WORKS
Use PDF and PowerPoint (PPTX) files of your product catalogs and service decks, and your product photos, as they are. You can also write a description in the input box.
STEP 01
Add product photos or product materials, and write which product and features you want to introduce.
STEP 02
Choose horizontal or vertical, then pick the narration voice and the presenter avatar.
STEP 03
Review the finished video, fix the script and subtitles, then export it as MP4 to use on product pages and in sales meetings.
ONE FORMAT, EVERY MODEL
More products, more models. NoLang uses a video you have made as the reference to create videos with different content, keeping the same design and structure.
Make your first introduction video from the catalog and photos of your main model. This video becomes the reference for the other models.
What changed
What changed
What changed
What's in one video, and the scenes that change per model
You can choose how closely to follow the reference video, from "Bold" to "Close to the reference." The instructions you enter take priority over the reference video.
PRODUCTS AND SERVICES
What you show determines what you add. Make product videos from photos, and service videos from documents and screen recordings.
Add product photos and a description, and you get an introduction video that shows the photos one at a time, in order, with narration and subtitles explaining the features.
Upload product photos with "From images" and enter a description.
You get a video with your photos inserted in order, one per scene.
Compare the photos and script with the actual product, then export as MP4.
Animating photos with AI clips may change shapes or logos. Check before publishing.
Make an introduction video from your service deck, then add a separately recorded screen recording as a scene later.
Add a PDF or PowerPoint (PPTX) file and choose "Explain key points only" or "Explain all pages."
Add your own videos with "Insert media" or "Create scene from video" in the editor.
Check that what appears on screen matches the script, then export as MP4.
Use screen recordings you have prepared yourself.
WHEN SPECS CHANGE
Spec figures, prices, new models. Each time something changes, fix only what changed. Just edit the script and confirm, and the video becomes a new version.
In the editor, rewrite the script where things changed. You can also fix images and subtitles.
Use "Regenerate audio" to regenerate the narration for that scene. Audio can be regenerated scene by scene.
Press "Confirm this content" and the video is regenerated as a new version.
Viewing and downloads switch to the new version. The video URL stays the same.
On the day of a change, update only that model's video to a new version
Editing is done on a PC. Until you confirm, the published video stays on the previous version.
LANGUAGES
With "Convert language," you can create a video in another language with the script and on-screen text translated. The Japanese video stays, so you can use each version in Japan and overseas.
Supports 34 languages, including English, Chinese, Korean, Thai, Vietnamese, and German. The available voices depend on the language.
The narration and subtitles are in the language you choose. Images on your document pages and text inside slides are not translated.
You can fix the translated script in the editor. For product names, model numbers, and units, it's best to have someone who knows the language check it.

CONCERNS, ANSWERED
How products look, the presenter, pronunciation, and screen format. Here are NoLang's answers to common concerns when making product and service introduction videos in-house.
We don't want AI-generated visuals to make the product look different from the real thing.
With NoLang
Choose "Use images as-is" and the photos you add are shown in order, one per scene. If you animate them with AI clips, check the shapes before publishing.
It's hard to find time for staff to appear on camera, let alone reshoot.
With NoLang
Choose a presenter from over 600 avatars, including real avatars that show a live-action person in motion. You can also create an avatar from a single photo of a staff member (the person's consent is required).
It might mispronounce model names or technical terms.
With NoLang
Fix how product names and model names are pronounced, word by word, and register up to 1,000 words in the dictionary. You can also change the narration speed.
Product pages need horizontal, social media needs vertical. We don't have the hands to make both.
With NoLang
Choose an aspect ratio such as horizontal 16:9 or vertical 9:16, and export as HD or Full HD MP4. You can also convert videos you make into versions in other aspect ratios.
COMPARISON
Comparing ways to make product and service introduction videos on 6 points.
| Point of comparison | Filmed by a production company | With NoLang |
|---|---|---|
| Getting started | Starts with discovery, planning, and storyboards | Starts by adding product photos or product materials |
| Adding products | A quote and an order for every video | Use one as the reference and make a video for each product |
| Spec and price changes | Request re-editing and re-recording | Fix the script for the scenes that change and confirm. A new version at the same URL |
| Showing the product | Shows textures and motion through filming, and internal structure with CG | Shows photos as-is. Footage you shoot can be added as media |
| Product screens | Request screen capture and editing | Add a separately recorded screen recording as a scene |
| Best for | A flagship brand video, fully produced with textures, usage scenes, and CG | High-volume videos made for each product and model and revised with every change |
Leave the elaborately produced video to a production company, and make per-product introduction videos with NoLang.
You can use both.
