NiceCodeScene Studio: turn a script and a set of images into video, synced to every sentence
Paste your script, drop an image on each scene, pick an AI voice or a clone of your own. The app generates the voice-over, times every image change to the words, lets you preview and fine-tune by hand, then exports MP4 with a Premiere timeline.

Four steps to a finished video
You handle the script and the visuals; the app does the tedious alignment.
Prepare script & images
One line of narration and one image per scene. Import from a spreadsheet or a JSON file. A scene with only a short title becomes a silent scene that shows its image for as many seconds as you set.
Pick a voice
Choose a system voice or clone your own from 3–10 seconds of audio. Voice profiles are saved to your account and reused across projects.
Generate voice-over, auto-align
The app shows the credit cost up front, generates voice-over in complete sentences, then re-transcribes the audio to place image changes exactly where the words fall.
Preview, fine-tune, export
Preview right in the app. Drag boundaries, add pauses, swap images, undo freely. Export MP4 or a Premiere timeline to keep editing.
Make narrated videos faster without giving up control
Automate the time-consuming parts and keep every detail adjustable.
AI voices, including your own
Multiple TTS engines managed centrally, no API setup on your end. Clone your own voice from a short sample; the voice belongs to your account.
Synced down to the word
Speech recognition captures the timing of every word and places image changes on sentence boundaries. Lines that drift too far are flagged so you can regenerate them.
Preview & hand-tune
Play audio with images switching along the playhead, right in the app. Drag boundaries, add pauses after sentences, swap any scene image, with undo/redo.
Fix one line, not the whole script
Regenerate only the lines you are not happy with; everything else comes from cache. Credits are charged for new audio only, and failed groups are refunded automatically.
Export MP4 + Premiere timeline
MP4 up to 4K, a finished audio track, and an XML that opens in Adobe Premiere with markers suggesting where to drop sound effects. Export per-scene audio named to match your images.
Silent scenes and title cards
A scene with only a short uppercase title gets no voice-over and shows its image for the seconds you set. Handy for title cards and section breaks.
Know the cost before you run
Before every generation the app estimates the characters and credits it will charge. If you are short on credits it tells you right away and points to a credit pack instead of stopping halfway.
Whole sentences, natural delivery
Consecutive lines that don't end a sentence are grouped so voice-over is generated in complete sentences, with no mid-sentence cuts.
One account, shared with Auto Flow
Sign in with the same email as the extension. Pro plans add Scene Studio credits every month; top up with credit packs when you need more, paid by bank transfer, PayPal or USDT.
Pay only for the voice-over you actually generate
1 credit = 1,000 characters, roughly 1 minute of audio. A video with 10 minutes of narration costs about 10 credits.
What you need to get started
A Windows PC
Windows 10/11. No GPU needed: voice generation runs on our servers, and video rendering runs locally on an ordinary office machine.
A script and an image per scene
PNG/JPG images for each scene, with per-scene narration in a spreadsheet or JSON. Batch-generate the images with Auto Flow and bring them straight in.
A NiceCode account
Sign in with your email and get 20 free credits. You need a connection to generate voice-over; alignment and export work offline.
Frequently asked questions about Scene Studio
What does Scene Studio run on? Do I need a powerful machine?
Windows for now. Voice generation runs on our servers, so you don't need a GPU; alignment and rendering run locally and an ordinary office PC is enough. You need an internet connection when generating voice-over.
How are credits counted? Does fixing one line cost the whole script again?
1 credit = 1,000 characters of text converted to speech, about 1 minute of audio. The app shows the credit cost before it runs. If a line doesn't sound right, regenerate just that line; the rest comes from cache and you only pay for what's new. Failed groups are refunded automatically.
What do I need to clone a voice?
A 3–10 second sample recording, clear and with little background noise. The app converts the format and creates a voice profile tied to your account; nobody else can see or use it. Shared system voices are available as well.
Do image changes follow the actual speech, or a fixed timing?
The actual speech: after generating the voice-over, the app re-transcribes the audio to get the timing of every word, then places each image change exactly between the last sentence of one scene and the first of the next. You can still drag any boundary by hand.
What can I export? Can I keep editing in Premiere?
MP4 (up to 4K), the finished audio track, and an XML timeline that opens directly in Adobe Premiere with the right image order, change points, and markers suggesting where to add sound effects. You can also export per-scene audio named to match your images.
Can I share an account with the Auto Flow extension?
Yes, same email. The extension's Pro plan adds Scene Studio credits to that account every month; buy a credit pack if you need more. Up to 3 signed-in devices across both products.
