Packaging lab and back-catalogue refresh

A video's title and thumbnail decide whether it is clicked; what keeps viewers watching decides whether YouTube keeps showing it. The packaging lab writes three title-and-thumbnail packages for a film, ready for YouTube Studio's own A/B test, and remembers what each test said. The back-catalogue refresh writes new packaging for an older YouTube video and applies it one change at a time — each one shown in full and agreed to before it runs.

What it does#

Three packages per film#

Every title and every word on a picture is checked by code before you see it: YouTube's rules, no promise, no AI label, no number the film's facts do not hold, and at most four words on a picture. A title the code strikes is written again. Each picture is a frame of the film at the moment that package is about, at 1280 × 720 (YouTube shows every option at the smallest one's size, so all three are full size), in the channel's brand type, under 2 MB.

Our critic — a model reviewing the packages as a phone's home feed would show them, never YouTube's data — scores each one out of 10 and marks our critic's pick. It is a second opinion; YouTube's test decides.

YouTube's test, staged for you#

YouTube's A/B test (in YouTube Studio) has no API, so a person starts it. The lab gives you everything to do it in a few minutes: each picture to download, each title to copy, and YouTube's steps:

1. On a computer, open YouTube Studio → Content, and open the video.
2. Click "A/B Testing" — in the Title field, or under the Thumbnail.
3. Choose "Title and thumbnail" (or "Title only" / "Thumbnail only").
4. Add the three packages, in their order — package 1 first: when a test is inconclusive, YouTube keeps the first one.
5. Click Done, then Save. Come back and press I started the test.
6. YouTube runs it for a few days up to two weeks and picks by watch time share, not clicks. When it ends, record what it said.

Once you press I started the test, ChannelForge changes neither the title nor the thumbnail of that video for 21 days, or until you record a result — the refresh below included. If you started nothing after all, press The test is not running.

The result teaches the next packages#

Record what YouTube said — A winner (and which package), Performed the same or Inconclusive. The channel's next packages are written knowing every earlier result, which the lab lists under "What this channel's earlier tests said".

The back-catalogue refresh#

For any YouTube video in Studio — made by ChannelForge or not — the refresh writes new titles, pictures and a description from the video's own facts, checks them the same way and scores them. For a Short it writes titles and a description only.

Nothing changes on YouTube until you apply one change:

• one change at a time — the title, the description or the thumbnail, never two at once and never anything else;
• shown in full first, with a box to tick, such as I agree: Change this video's title on YouTube from "…" to "…". Nothing else changes.;
• exactly what you agreed to — the change is sent only if its value is the very one you agreed to; an altered value is refused;
• never the visibility — a refresh can never make a video public, private or unlisted, or change any other setting;
• reversible — each change is recorded in Studio's Changes with what it replaced and YouTube's answer, with its Revert (the old thumbnail is kept for 30 days for that).

YouTube's own numbers for the video at the first change are kept and shown, as YouTube reports them, beside today's — so you can see what happened, in YouTube's figures rather than ours.

How to use it#

Packages for a film#

1. Open Long-form, the film, then its Publish tab. The Packaging lab is there once the film is ready (a held film is never posted, so it gets no packages).
2. Optionally write A note for the writer, for example "lean on the record it sets; keep the series name".
3. Press Write three packages. The price is shown beside the button. Writing takes a few minutes; reload to see them.
4. Download each Picture, use Copy the title, and start the test in YouTube Studio as above.
5. Press I started the test. When YouTube's test ends, choose What YouTube said and The winner, then Record the result.

Editors, admins and owners write packages and record tests. Viewers read them.

Refresh an older video#

1. Open Studio, find the video in Library (or follow a link to Refresh), open it, then its Edit tab.
2. Optionally add A note for the writer, then press Refresh its packaging. The price is shown beside it.
3. Read each title, picture and the description. For the one you want, tick I agree: … and press Apply this title, Apply this picture or Apply this description.
4. Follow the change under The refresh's changes; Every change, with its Revert opens Studio's Changes.

Studio's Refresh page lists the latest refreshes and the workspace's 30 newest YouTube videos; open any other from Library.

Credits and plans#

Writing packages, or a refresh's packaging, is charged what it used (the writer and the critic), at your plan's markup, like any job: it reserves a few credits before it starts and the price is shown beside the button. Applying a change costs no credits. A job that fails on our side is not charged.

Limits and good to know#

• Automatic picks wait for YouTube. ChannelForge can suggest videos worth refreshing — long-form videos with good retention but weak click-through against your channel's own medians — but that comparison is a figure of our own made from YouTube's numbers, which needs YouTube's approval of our derived-metrics amendment. Until then the Automatic picks say so and list none; choosing a video yourself needs none of it.
• The refresh is for YouTube. It changes a published video's title, description and thumbnail there. Elsewhere, Studio can change a Facebook video's thumbnail; Instagram, TikTok and LinkedIn take a cover only at upload.
• A test in progress is protected for 21 days after you said it started, or until its result is recorded.
