Voiceover to Video for narration that already carries the message

Keep the voiceover your team already approved. Upload the MP3, tell ngram who the video is for, and build the visuals around the recorded words. Review the result with sound on before sharing.

How it works

From your recorded voiceover to a reviewed video

Keep the recording as the spoken source and give ngram the audience and visual direction. Review the plan and finished result before delivery.

01

Upload the approved MP3

Use an MP3 up to 25 MB. Upload the clean voice recording you want in the result. For WAV, M4A or another format, export an MP3 from your recording tool first.

02

Name the recording’s job

Review the brief in Studio and say the attached file is the voiceover. Add the audience, purpose and any required visuals. If you also attach music, name that file separately as background music.

03

Review the visual plan

Check that the planned explanation follows the recording. Request changes before approving production when a plan is offered. The recording supplies the voice; it does not replace the need to review factual claims or visual details.

04

Play and deliver the result

Listen from beginning to end. Check the original words, scene changes and any captions you enabled. Share the reviewed result or download its MP4 on a paid plan; prepare another aspect ratio as a separate edit.

Output controls

Keep the recording. Shape the surrounding video.

Build scenes around the spoken explanation

Describe the visual direction and supply real product images or recordings when an accurate interface matters. Check every scene against the spoken explanation.

Optional captions

Turn captions on when you need them and review the wording and timing in the finished preview. Captions start off.

Your visual direction

Ask for diagrams, motion text, imagery or product visuals that support the recorded message. Identify any source image that must remain recognizable.

One reviewed ratio per edit

Choose landscape, square or vertical for the intended destination, then review each version separately.

Optional background music

Attach a second MP3 and say it is the background music. Name both files by role and listen for words obscured by the track.

Review a shorter cut separately

For a shorter deliverable, identify the passage to keep and ask for a separate cut. Replay its beginning and ending before delivery.

A different language needs a new spoken track

Keeping the original recording preserves its language. A translated version uses different narration; review that as its own deliverable.

How it compares

If you've been using something else to put a video behind a voiceover.

Choose the workflow that fits your source. ngram accepts an MP3 in the brief and builds around the role you specify. Other editors offer their own recorded-audio paths, with different format and plan limits.

Common questions about voiceover to video

What audio formats does the voiceover to video converter accept?

Upload MP3, up to 25 MB, for the recorded-narration path. WAV, M4A, AAC, OGG and FLAC are not accepted by this Studio source workflow. Export an MP3 first, or paste the script if you want generated narration.

What does the output look like?

A video built around your recorded message with the supporting visuals you describe. Choose a Brand Kit and any saved opening separately. Enable captions when needed, and review the finished preview before sharing or downloading on a paid plan.

How does ngram use my recorded voiceover?

The MP3 arrives as an audio source. The brief identifies it as the voiceover and asks ngram to keep it as recorded while creating supporting visuals. Play the result to verify the words and transitions; do not rely on the presence of an attachment alone.

How long does a voiceover to video conversion take?

Upload the MP3 and wait for the source to be ready. Review the brief and any proposed plan, approve production, then wait for the playable preview. The time depends on the video and generation work.

Can I make versions for different placements?

Prepare and review each aspect ratio as a separate edit. Check the crop and text size in the intended placement rather than assuming a single export fits every channel.

Can I translate the voiceover and captions?

A different spoken language requires a translated narration track. Keeping the uploaded recording preserves its original words and language. Review the translated version separately.

What if I have not recorded a voiceover yet?

Choose Paste a script. ngram generates narration from that text. This is a different input from preserving an MP3 recording.

Can I also provide my own music?

Yes. Attach the music MP3 separately in Studio and say which file is the voiceover and which is background music. Replay the mix so the spoken instructions remain clear.

Can I automate recorded MP3 narration through a connector?

Use the Studio upload path for the workflow described here. API and assistant integrations have their own documented inputs; a text-to-video action does not establish support for attaching recorded narration.

What should I check before sharing?

Compare the result with the original recording, including names, numbers, opening and ending. Review optional captions and the volume of any music. Ask the source owner to confirm factual or training content before delivery.
