Where the apps cover the frame

ViewGum uses one safe box for all four apps, so the same cut posts to Instagram Reels and the others with nothing important covered. The box is for regular posts. For an ad, follow the ad safe zone listed above.

Covered by the app, in a 1080 x 1920 frame

The top 8% of the frame, where the feed's tabs sit.
A column down the right 17%, from 46% to 73% of the way down, where the like, comment, share and save buttons sit.
The bottom 27% of the frame, where the account name, the post text and the sound sit.

The safe box, where captions, titles and graphics go.

How each short is tuned for Instagram Reels

Hooks

The short opens on a specific claim, result, number or contrast of 6 to 14 words. In an uploaded take, that line moves to the front and the video starts on its first word. A title of 3 to 8 words shows it on screen from the first frame, for viewers with the sound off.

Captions

Captions show one word at a time, or 2 to 6 words as the edit style sets, with a word or phrase picked out. They stay inside the safe box, clear of the buttons and post text on Instagram Reels.

Pacing

Greetings, channel intros, false starts and "like and subscribe" lines are cut. Long pauses go too, as tightly as the edit style asks. Punch-ins land on the peak word of a beat, spaced as the edit style sets.

Retention

After the hook, every line adds something new on the way to the payoff. If a take never pays off its opening, the editor's notes say so and suggest a better first line before you export. Each idea lists the platforms it suits, and its script is written for them.

Post copy for Instagram Reels

The cover text is three to seven words.
The caption is two to four short sentences, under 400 characters, and its first line carries the words people would search for.
Three to 5 hashtags about the topic, never generic ones like #reels or #explore.
The copy only says what the video says: no invented results, numbers, offers or urgency, no exclamation marks, and titles in sentence case.

Questions

What does ViewGum export for Instagram Reels?

A 1080 x 1920 vertical MP4 (9:16) with the captions burned in, and a title, a caption and hashtags written for Instagram Reels. You download it and post it yourself.

Will the Instagram Reels buttons cover my captions?

Not on a regular post. ViewGum keeps captions, titles, graphics and faces inside one safe box, clear of where the apps draw their tabs, buttons and post text. For an ad, follow the platform's ad safe zone.

Do I have to be on camera?

No. A faceless short starts from an idea and gets a voiceover and pictures. If you record yourself, upload the take and ViewGum edits it.

Can I post the same short on other platforms?

Yes. One cut fits all four, and the post copy is written for each platform on its own.

What goes on the cover?

Three to seven words of cover text that say what the Reel is about, and the caption's first line repeats the words people would search for.
