Upload Video to Valmera: Formats, Limits and Link Imports

Upload your recorded video and any clips, images or music you want to include. You can also ask the agent to import a supported media link. Check the limits for the route you use, then confirm that the source is ready before requesting and reviewing the edit.

Updated 2026-09-08. Direct-upload formats and limits checked against the live service. Account creation and uploads are free; indexing and agent editing require a subscription and processing credits.

What Can You Upload?

Your main video supplies the source footage for the edit. Source analysis builds a transcript when speech is present and provides information about shots and silence. Both video limits apply: up to 14 GB and up to 3 hours per file. Transfer and analysis are separate stages; larger files and longer recordings can take more time.

You can also add supporting assets: extra clips the agent inserts at any point in the video, images that get spliced in with Ken Burns motion, and a music track that becomes the soundtrack — with automatic ducking under speech and per-layer volume control. You can also skip the main video entirely and build a canvas project out of images, clips, and music.

Studio does not import or export SRT/VTT subtitle files. It generates transcript captions from speech and burns them into the final MP4. See Auto Captions.

File type and encoding are different. An MP4 or MOV extension identifies a container; its video and audio use particular codecs. A supported extension does not prove that a damaged or unusual file can be decoded. Renaming a file to .mp4 does not convert it. The MDN media-format guide explains this distinction.

Paste a Link Instead of a File

Paste a direct media URL or a supported page link into chat and describe what to import. Platform pages such as YouTube, TikTok, Vimeo or SoundCloud require the service to retrieve the underlying media. Retrieval can fail for a private, removed, restricted or provider-blocked item. A link working in your signed-in browser does not guarantee that Valmera can retrieve it.

  • Link imports use their own transfer caps: clips up to 500 MB, audio up to 50 MB, images up to 10 MB.
  • The platform extractor requests video up to 1080p when available; fallback formats and direct-file downloads can differ. Upload the original when you need control over the source quality.
  • Maximum 60 minutes for imported video or audio. Link-import limits are separate from the larger direct-upload video allowance.
  • Only use media you have the rights to use — pasting a link does not grant you a licence to someone else's work.

Need media that does not exist yet? The agent can also generate images, sound effects, and short video clips inside the edit — see AI Generation & Imports.

How to Upload

1

Choose the Source and Project

Upload the recorded video in Studio. Check the filename, format, size and duration. When adding several assets, inspect the staging tray and confirm which footage is intended as the main source.

2

Check Transfer and Analysis Progress

Keep the page open while the transfer is active and read the current project status. Source analysis and previews may involve a proxy while the original continues transferring. Wait for the original before final export.

3

Add and Identify Supporting Assets

Attach extra clips, images or music to the intended project. Name the asset in your request and explain whether it should be inserted, overlaid, used as music or kept as a reference. Merely uploading an asset does not specify its placement.

4

Describe the Edit and Review It

For example: "Insert the screenshot named pricing.png at preview time 2:14 for five seconds." Check the current preview and correct the result. Say whether timestamps refer to the source or the edited preview.

Best Practices

  • Pair footage with a clear request. Do not just upload a clip — say what you want from it. "Turn this into a 60-second teaser" beats an upload with no instructions.
  • Upload your highest-quality source. Previews render from a fast proxy, but the final export uses the original file. Encoding, cropping, output settings and source quality still affect the result. Keep your original and inspect the delivered MP4.
  • Add music early. If you want a soundtrack, bring it in during your first messages so the agent can balance ducking and levels as it builds the cut. Upload your own track, paste a link to one, or ask the agent to find one on the web.
  • Check both limits before uploading. A four-hour file is too long even if it is small; a 20 GB file is too large even if it is short. Trim or split an overlong source. A smaller encoding may help with file size, but it can change quality and does not shorten the recording.

If an Upload or Import Fails

Unsupported or empty file

Check the exact extension and that the file has finished exporting or downloading. Open the source locally. Renaming an extension does not repair the encoding or an incomplete file.

Video exceeds a limit

Use the reported size and duration to identify the problem. Trim or split an overlong recording; reduce file size with a suitable export if needed, keeping the original and checking the converted result.

Transfer appears stuck

Read the current transfer status and any error. Keep the tab open during an active transfer. If the page or connection was interrupted, reopen the intended project and inspect what completed before starting another upload.

Upload finished but editing is unavailable

Check whether source analysis is still running or the account needs a subscription or processing credits. A completed file transfer alone does not prove readiness for editing.

A link serves a login page or cannot be fetched

Use an authorized original file or a supported direct media URL. Do not keep retrying a private, removed or blocked link unchanged; the agent must be able to retrieve actual media.

A preview exists but the final export is waiting

Check whether the full original has finished uploading. A proxy preview and an original-source final render have different readiness requirements.

Upload Questions

Can I upload my own footage to Valmera?

Yes. Studio accepts MP4, MOV, M4V, MKV and WebM video files. Each video must meet both limits: no larger than 14 GB and no longer than 3 hours. Upload your recording, wait for the relevant transfer and analysis steps, describe the edit, review the preview and create the final MP4 in Studio.

Is 14 GB an alternative to the 3-hour limit?

No. Both limits apply to every video upload. A 1 GB recording lasting four hours is too long; a 20 GB recording lasting twenty minutes is too large. Trim or split an overlong recording. For an oversized file, consider a smaller encoding and check its quality before uploading.

What image and music formats can I attach?

Images: PNG, JPG, JPEG and WebP, up to 50 MB each. Music: MP3, WAV, M4A, AAC and OGG, up to 50 MB each. Extra video clips use the supported video formats and must fit both the 14 GB and 3-hour limits. Accepted extensions do not guarantee that a damaged or undecodable file will process.

Can I import a video from a link instead?

You can ask the agent to import supported public media links. Link imports have separate limits: video clips up to 500 MB, audio up to 50 MB, images up to 10 MB, and timed media up to 60 minutes. A platform page may fail because the item is private, removed, restricted or blocked by the provider. Upload an authorized original file when the link cannot be retrieved.

Does upload completion mean the video is ready to export?

No. Transfer, source analysis, preview rendering and final rendering are separate stages. Some uploads prepare a proxy while the original continues transferring. Check the project status and wait for the original before final export. A visible preview is not proof that the full original upload has finished.

Can I upload SRT or VTT subtitles to Studio?

Studio does not import or export SRT/VTT files. Its transcript captions are generated from speech and burned into the MP4. Valmera's separate free subtitle utilities work with existing subtitle files; they do not provide subtitle-file import for Studio.
