The video agency tool stack: software for a small production or social media agency

A freelance editor juggles clients. An agency juggles clients, editors, designers, account managers and channels, all at once. The problems that a solo editor solves with good habits need systems at agency scale: who can see which client's work, who approves what, which version went out, and who's allowed to press publish on a client's channel.

This post walks through the stack for a small video agency, from five to thirty people, whether you make ads and brand films, run YouTube channels for creators, or produce short-form for social. We make Seamlift, which covers review, approvals and YouTube publishing; for the other slots we've listed the tools agencies commonly use.

What changes at agency scale

Compared with a solo editor, an agency needs:

1. Separation between clients. Client A must never see Client B's unreleased video.

2. Roles. Editors upload, account managers coordinate, clients review, and only some people publish.

3. Many reviewers per video. The client's marketing lead, their legal team, a sponsor, the creator.

4. Many channels. Each client's YouTube channel or social accounts, without collecting anyone's passwords.

5. Costs that don't explode with headcount. Freelancers come and go; client reviewers shouldn't each cost a seat.

1. Editing and finishing

• Premiere Pro and After Effects: the most common pairing in agencies, and what most freelancers you hire will know.

• DaVinci Resolve: for colour, and increasingly for the whole edit.

• CapCut: for fast short-form turnaround on social accounts.

Agree a house standard for project structure, naming and export presets, so any editor can pick up any project.

2. Assets and brand kits

Every client has logos, fonts, colours, lower thirds and intro animations. Keep them in one place per client, not in an editor's downloads folder.

• A shared Assets folder per client project. In Seamlift, every project has one, shared with Premiere Pro, Illustrator and Blender through their integrations: designers upload from Illustrator, editors pull new files into Premiere with one button, and nothing gets overwritten. More on the designer-to-editor handoff.

• Google Drive or Dropbox for raw footage and archives, which are too big to keep anywhere expensive.

3. Client review and approvals

This is the slot that decides whether an agency feels organised to its clients.

What to look for:

• Clients review from a link, with no account. Clients won't sign up for your tools.

• Notes on the exact frame, so "the logo at the end" means one frame.

• One list of notes per version, including the client's, the account manager's and the creative director's, with a status on each.

• Control over links: passwords, expiry dates, downloads off, revoking at any time.

• Pricing that doesn't charge per reviewer.

With Seamlift:

• Each client gets its own workspace, so their projects, members and channels are separate from every other client's.

• Clients and sponsors review from share links, with guest comments on. Their notes land in the same list as your team's, and can be marked as change requests or questions.

• Your team marks each note to do, in progress or done, so an account manager can see where every video stands without asking.

• Every version stays in the project with its own notes, which settles "we never asked for that" in seconds.

Other tools agencies use here include Frame.io for Adobe-heavy post work and Filestage for formal multi-step approvals across video, PDFs and designs. Here's how they compare.

4. Roles and permissions

Agencies need to be precise about who can do what, especially once freelancers are involved.

Seamlift workspaces come with built-in roles:

• Owner and Admin: everything, including connecting channels and publishing.

• Editor: creates projects, uploads cuts and prepares YouTube drafts, but can't publish.

• Reviewer: watches and comments.

• Viewer: watches and reads notes.

You can create custom roles for anything in between, like an account manager who can create share links and publish but doesn't manage members, or a freelance editor who can upload but not see share links.

Members don't cost extra, so you can add a freelancer for one project and remove them when it's done without thinking about seats.

5. Channels and publishing

For agencies running YouTube channels, publishing is where risk lives. Never collect clients' Google passwords.

• YouTube Studio permissions: clients can invite your team to their channel as Editor or Editor (limited), so you can upload and edit without their password.

• Publishing from the review tool: in Seamlift, the client connects their channel once through Google's own sign-in and shares it with their workspace. Your team prepares the title, description, thumbnail, tags, playlists and captions during review, and the approved version goes to YouTube without being downloaded and uploaded again. Only roles with the Publish permission can send it, and the client can remove the channel from the workspace at any time.

What does a YouTube channel manager use to approve videos?

A channel manager needs three things: a place to see every video in progress and its state, a way to give notes that the editor can act on, and control over what goes live. The usual setup is a review tool for cuts and notes, a project board for the content calendar, and either YouTube Studio permissions or a review tool that publishes. In Seamlift, the manager reviews and comments on the cut, checks the YouTube draft alongside it, and publishes or schedules the approved version.

6. Project management and the content calendar

• Notion: briefs, scripts and a content calendar per client.

• ClickUp, Asana or Monday.com: for agencies with many parallel projects and task dependencies.

• Airtable: for production tracking with lots of structured fields.

Keep the calendar and the review tool linked: each calendar item links to the video's project.

7. Communication

• Slack or Microsoft Teams internally, with a channel per client.

• Shared Slack channels or WhatsApp groups with clients, if they want them. Keep feedback on the video in the review tool, not in chat; ask clients to leave notes on the frame.

8. Billing and finance

• QuickBooks, Xero or Zoho Books for accounts and invoicing.

• Retainers for ongoing channel or social work, billed monthly; project fees for one-off productions.

• Track revision rounds per project. If a client regularly goes past the rounds in their contract, that's a conversation, or a change order.

For agencies in India, tools that bill in INR and accept UPI save clients and you the foreign card fees. Seamlift prices in INR with GST included for India, and in USD elsewhere, and charges for storage only, so adding client reviewers or freelance editors never changes the bill. See pricing.

FAQ

What software stack does a small video production agency need?

An editing suite (Premiere Pro and After Effects, or DaVinci Resolve), shared storage for footage, a review tool where clients leave notes on the frame without an account, roles to control who sees and publishes what, a project board, team chat, and accounting software.

What tools does a social media agency use for client video?

Fast short-form editing (CapCut or Premiere Pro), a shared brand-asset library per client, a review tool for client sign-off, a content calendar in Notion or ClickUp, and publishing access to each client's channels through official permissions rather than passwords.

What does a YouTube channel manager use to approve videos?

A review tool for cuts and frame-accurate notes, a content calendar, and either YouTube Studio's channel permissions or a review tool that publishes. With Seamlift, the manager reviews the cut and its YouTube draft together, then publishes or schedules the approved version.

How do agencies keep clients' work separate?

Give each client its own workspace or space in every tool, with only that client's team and your assigned staff as members. In Seamlift, each workspace has its own projects, members, roles and connected channels.
