Reels is Instagram's short vertical video format, shown full-screen in a 9:16 frame inside the Instagram app. Like other short-video feeds, Reels expects vertical footage and will crop or pad video that doesn't already fill that frame, so exporting your compilation already in 9:16 avoids Instagram making that decision for you.
Resolution, duration and re-encoding
Instagram accepts MP4 uploads and re-encodes them for delivery across devices and connection speeds, so whatever bitrate you export at, Instagram's own compression is the last word on final quality. Instagram has changed its maximum Reels length more than once as the format has evolved, so rather than quoting a number here that may already be outdated, check the current limit in the Instagram app before you plan an edit longer than a minute or two. For most repurposing and highlight use, a 60-second ReelWorkshop edit sits comfortably inside whatever the current ceiling is.
For resolution, export at 1080x1920 for the sharpest result on modern phones; 720x1280 is a reasonable fallback if you're managing file size or your monthly export minutes on the Starter plan.
Configuring the export
| Setting | Recommendation | Why |
|---|---|---|
| Length | 60s edit plan | Matches typical Reels viewing habits; confirm current max length in-app before going longer |
| Resolution | 1080x1920 | Sharpest playback on current phone screens |
| Audio | Keep, unless adding Instagram audio | Avoids double audio tracks after upload |
| Format | MP4 (H.264/AAC), ReelWorkshop's only export format | Matches what Instagram expects for upload |
Instagram's on-screen safe areas
Instagram overlays the caption, username, audio title and the like/comment/share/save icon column over your video, generally along the bottom edge and down the right side. There's also a small overlap with the main feed's top bar when Reels are viewed from certain entry points. If your compilation includes on-screen text, keep it centered and away from the outer 10-15% of the frame on the sides and bottom rather than assuming the whole 1080x1920 canvas will be visible to the viewer.
Use ReelWorkshop's live preview to check where your clips place any burned-in text or logos before rendering, since renders count against your monthly export minutes on the Starter plan.
Common mistakes
- Exporting at 720x1280 out of habit when 1080x1920 would look meaningfully sharper for a final Reel.
- Placing captions right at the bottom edge, where Instagram's caption and icon overlay usually sits.
- Building a 90-second edit for a use case that needs to fit a shorter length Instagram currently enforces — verify the app's current limit first.
- Forgetting to mute the export when planning to add licensed Instagram audio afterward, resulting in two overlapping soundtracks.
When to use something else
If your Reel needs trending audio, Instagram's text animations, stickers, or auto-generated captions, add those inside Instagram after uploading — ReelWorkshop doesn't do captioning or audio library selection. ReelWorkshop's job here is producing a clean, correctly framed vertical MP4 from your own footage; Instagram-native polish happens after that.
Will ReelWorkshop crop my clips to 9:16 automatically?
ReelWorkshop's exports are vertical 9:16 MP4 by design (1080x1920 or 720x1280); how your individual source clips fill that frame depends on their original framing and any trims you make before rendering.
Does Instagram support the exact file ReelWorkshop produces?
Yes — ReelWorkshop exports H.264 video with AAC audio in an MP4 container, which is a standard format Instagram accepts for Reels uploads.
