Frequently asked questions
Can you schedule Instagram Reels in advance?
Yes. Submagic connects to your Instagram account via OAuth and publishes or schedules Reels on your behalf. Pick your date, time, and timezone. Submagic posts your Reel automatically at the scheduled time.
How do I schedule a Reel on Instagram?
Upload your video to Submagic and add AI captions and effects. AI generates your caption in the editor. Open the publish screen, toggle Instagram on, select the Reel format, review the pre-filled caption, pick your date and time, and hit Schedule. Submagic handles the rest.
Does Submagic add captions to Reels before scheduling?
Yes. Submagic is a video editor first. You add AI-generated captions, B-roll, transitions, effects, and sound inside the editor, then schedule the Reel directly to Instagram. No need to edit in one app and upload to another.
Can I schedule Reels and Stories at the same time?
Yes. In the publish screen, you can schedule both Reels and Stories to Instagram from the same session. Each format gets its own content, captions, and scheduling time. You can also schedule to TikTok and YouTube Shorts in the same flow.
Is scheduling Instagram Reels free?
Free users can connect Instagram and publish one Reel via Publish Now, no credit card required. Scheduling Reels for a future date and time requires a Pro or Business plan. Scheduling is included in the subscription at no extra charge.
What is the best time to post Reels on Instagram?
Peak engagement times vary by audience, but common high-activity windows are morning commutes (7-9 AM), lunch breaks (12-1 PM), and evenings (7-9 PM) in your audience's timezone. Submagic lets you schedule Reels for any time and timezone, so you can test different posting windows.
Can I schedule Instagram Reels and TikTok videos at the same time?
Yes. AI generates tailored details for each channel in the editor. Toggle on both Instagram and TikTok in the publish screen, review the pre-filled fields, schedule once, and Submagic publishes to both platforms at the set time.
What Reels formats does Submagic support?
Submagic formats your video in vertical 9:16 for Instagram Reels. You see a live preview of exactly how the Reel will appear on Instagram before you schedule or publish, including captions, effects, and the first comment.
Why use Submagic instead of scheduling Reels natively in Instagram?
Instagram lets you schedule Reels up to 30 days ahead, but only from the mobile app, and only after you finish editing elsewhere. Submagic handles editing and scheduling in one step: add AI captions, B-roll, and effects, then schedule to Instagram without downloading or re-uploading. You also get AI-generated captions and first comments that native scheduling does not offer.
