Uploading Footage & Assets

Upload the video you want edited, plus any assets the agent should work into the cut — extra clips, images, and music. Or paste a link and the agent pulls the media in for you.

What Can You Upload?

Your main video is the raw material of every edit. Upload it and Valmera analyzes it before making a single change — building a word-level transcript, detecting shots, and mapping silences. Main videos can be up to 2 GB and up to 3 hours long, and long recordings are fully supported; analysis runs once per upload and scales with the length of the file — longer files take longer, and progress is visible while it runs.

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.

Supported File Types & Limits

MAIN VIDEO

  • MP4
  • MOV
  • MKV
  • WebM & similar

Up to 2 GB / 3 hours

EXTRA CLIPS

  • Same video formats
  • Inserted at any point

Up to 500 MB each

IMAGES

  • PNG
  • JPG / JPEG
  • WebP

Up to 10 MB each

MUSIC

  • MP3
  • WAV
  • M4A

Up to 50 MB

Subtitle files (SRT/VTT) are not needed — captions are generated automatically from the word-level transcript. See Auto Captions.

Paste a Link Instead of a File

If the media you want is already on the web, you do not have to download it first. Paste the link into the chat — a direct file URL, or a page on a platform like YouTube, TikTok, Vimeo, or SoundCloud — and the agent pulls the video, song, or image into your project as an asset you can then edit like any other.

  • Same size caps as uploads: clips up to 500 MB, audio up to 50 MB, images up to 10 MB.
  • Link pulls are capped at 1080p — for anything higher, upload the original file.
  • Maximum 60 minutes of duration per pulled item.
  • 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

Start With Your Main Video

Upload the video you want edited from the Studio. This creates your project — everything else attaches to it.

2

Let the Analysis Run

Valmera builds the word-level transcript, detects shots, and maps silences. Longer uploads take longer — progress is visible while it runs.

3

Add Assets as You Go

Attach extra clips, images, or a music track alongside a chat message — or drop a file straight onto the timeline to insert it at that point. Pasting a link works too: the agent pulls that media in as an asset.

4

Tell the Agent What to Do With Them

For example: "Put this track under the whole video and duck it when I speak" or "Insert this screenshot at 2:14 for five seconds."

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 renders from your original file — the quality you upload is the quality you get back.
  • 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 for something from the built-in royalty-free library.
  • Long videos are fine. The 2 GB / 3-hour ceiling comfortably fits long recordings. Just expect the initial analysis to take longer on longer files — after that, edits are conversational.
