Creating videos is only half the battle. Getting them published across multiple platforms traditionally means downloading files, opening each app, uploading separately, and manually entering captions and descriptions. Vexub eliminates this workflow entirely with direct social media publishing.
The Vexub Publish feature connects your TikTok, YouTube, and Instagram accounts directly to your workspace, allowing you to post finished videos with a single click. No downloads, no re-uploads, no copying and pasting captions between platforms.
This guide walks through connecting your accounts, configuring platform-specific settings, and publishing videos optimally for each network.
Connecting Your Social Media Accounts
Before you can publish from Vexub, you need to authorize the platform to post on your behalf. This is a one-time setup process for each account.
Connecting TikTok
Navigate to Settings: Click your profile icon in the top-right corner, then select Settings from the dropdown menu.
Access Connected Accounts: In the settings sidebar, click Connected Accounts to view all available platform integrations.
Authorize TikTok: Click Connect TikTok and you'll be redirected to TikTok's authorization page.
Grant Permissions: Log into your TikTok account and approve the permissions request. Vexub needs access to post videos and read basic account information.
Confirm Connection: You'll be redirected back to Vexub with a success message. Your TikTok username will now appear in the Connected Accounts section.
Connecting YouTube
YouTube integration requires a Google account connection:
Click Connect YouTube: In the Connected Accounts section, select the YouTube option.
Choose Google Account: Select the Google account associated with your YouTube channel. If you manage multiple channels, ensure you select the correct account.
Review Permissions: Google will display the specific permissions Vexub requests. These include uploading videos and managing your YouTube channel.
Allow Access: Click Allow to authorize the connection.
If you manage multiple YouTube channels under one Google account, you'll be able to select which channel to publish to during the publishing process.
Connecting Instagram
Instagram requires both an Instagram Business or Creator account and a connected Facebook Page:
Convert to Business Account: If you haven't already, convert your Instagram account to a Business or Creator account in the Instagram app settings.
Link Facebook Page: Connect your Instagram account to a Facebook Page you manage.
Connect in Vexub: Click Connect Instagram and log in with your Facebook credentials.
Select Instagram Account: Choose which Instagram Business account you want to connect from the list of accounts linked to your Facebook Pages.

Publishing Your First Video from Vexub
Once your accounts are connected, publishing is straightforward. After you've finished editing a video using Vexub's AI video creation tools, follow these steps:
Starting the Publish Process
Complete Your Video: Ensure your video is fully edited with captions, voiceover, music, and any other elements you want included.
Click Publish: In the top-right corner of the editor, click the Publish button (distinct from the Export button).
Select Platforms: A dialog appears showing all your connected accounts. Check the boxes next to each platform where you want to publish this video.
You can publish to one platform, all platforms, or any combination. Each platform can have different settings configured in the same workflow.
Configuring TikTok Publishing Settings
When TikTok is selected, you'll see TikTok-specific options:
Caption: Enter your video caption (maximum 2,200 characters). Include relevant hashtags and calls-to-action.
Privacy Level: Choose Public, Friends, or Private. Most creators select Public for maximum reach.
Allow Comments: Toggle whether viewers can comment on your video.
Allow Duet/Stitch: Enable or disable other users' ability to create duets or stitches with your video.
Cover Image: Vexub automatically selects a frame from your video, but you can choose a different frame or upload a custom cover.
TikTok posts appear on your profile immediately after publishing. Vexub automatically optimizes the video format for TikTok's specifications, ensuring proper aspect ratio and encoding.
Configuring YouTube Publishing Settings
YouTube offers the most comprehensive publishing options:
Title: Enter your video title (maximum 100 characters). This is crucial for YouTube SEO.
Description: Write a detailed description (up to 5,000 characters). Include timestamps, links, and relevant information.
Visibility: Choose Public, Unlisted, or Private. You can also schedule a premiere or set a specific publish time.
Category: Select the most relevant category (Education, Entertainment, How-to & Style, etc.).
Tags: Add relevant keywords as tags to help with discoverability.
Thumbnail: Vexub generates a thumbnail from your video, or upload a custom 1280x720 image.
Playlist: Add the video to an existing playlist to organize your channel content.
Age Restriction: Indicate whether the video is made for kids or contains mature content.
Configuring Instagram Publishing Settings
Instagram Reels publishing includes:
Caption: Write your caption (maximum 2,200 characters) with hashtags and emojis.
Cover Image: Select a frame from your video to use as the cover that appears in your profile grid.
Location Tag: Add a location to increase local discoverability.
Share to Feed: Toggle whether the Reel also appears in your main Instagram feed.
Enable Sharing: Allow or disable users sharing your Reel to Stories.
Instagram Reels must be between 3 seconds and 90 seconds. Vexub will warn you if your video exceeds this duration and offer to trim it automatically.
Multi-Platform Publishing Strategy
Publishing to multiple platforms simultaneously saves time, but each platform has different audience expectations. Here's how to optimize for each:
Platform-Specific Caption Strategies
TikTok: Keep captions concise and use 3-5 targeted hashtags. TikTok's algorithm prioritizes watch time over caption keywords. Include a hook in the first line since only the first 100 characters show before 'more' appears.
YouTube: Write detailed descriptions with timestamps, links to related videos, and relevant keywords. YouTube's search algorithm heavily weights description content. Include your most important information in the first 150 characters, which appear in search results.
Instagram: Front-load your caption with the most important message since only the first 125 characters appear before the 'more' button. Use line breaks for readability and place hashtags at the end or in the first comment.
Optimal Posting Times
While Vexub allows instant publishing, scheduling for peak engagement times increases initial views, which signals platform algorithms to show your content to more people:
TikTok: Peak times are typically 7-9 AM, 12-1 PM, and 7-9 PM in your target audience's timezone. Vexub's scheduled publishing feature lets you set exact publish times.
YouTube: Early afternoon (2-4 PM) on weekdays performs well for most niches. Consistency matters more than specific times on YouTube.
Instagram: Reels perform best during 11 AM - 2 PM and 7-9 PM. Instagram's algorithm favors content that generates quick engagement.
Publishing Workflows for Different Content Types
Different video types require different publishing approaches. Here are proven workflows for common content categories:
Short-Form Viral Content (Under 60 Seconds)
Create your video in Vexub using trending topics or formats.
Publish simultaneously to TikTok and Instagram Reels for maximum reach.
Use identical captions on both platforms, adjusting hashtag strategy slightly (TikTok: trending hashtags, Instagram: niche-specific hashtags).
Skip YouTube for sub-60-second content unless it's part of a YouTube Shorts strategy.
Monitor engagement in the first hour. If a video performs well on one platform, consider creating a YouTube Short version with a custom thumbnail.
Educational or Tutorial Content (1-3 Minutes)
Publish to YouTube first as your primary platform, using detailed descriptions and proper categorization.
Create a shorter 60-second teaser highlighting the key point or result.
Publish the teaser to TikTok and Instagram with a caption directing viewers to YouTube for the full tutorial.
Add the YouTube video to a relevant playlist to increase session watch time.
Series or Episodic Content
Establish a consistent publishing schedule across all platforms.
Use Vexub's scheduled publishing to queue up multiple episodes in advance.
Include episode numbers in titles and captions for all platforms.
On YouTube, create a dedicated playlist and link to it in every video description.
Cross-reference episodes in captions: 'See Episode 3 in my bio link' (Instagram/TikTok) or 'Watch Episode 3 here: [link]' (YouTube).
Troubleshooting Common Publishing Issues
Even with direct integrations, occasional issues arise. Here's how to resolve the most common problems:
Failed TikTok Uploads
If your TikTok upload fails, check these factors:
Video Duration: TikTok accepts videos from 3 seconds to 10 minutes, but shorter videos (under 60 seconds) perform better algorithmically.
Copyright Issues: TikTok may block uploads containing copyrighted music detected by their system. Vexub's royalty-free music library avoids this issue.
Account Status: Ensure your TikTok account is in good standing. Accounts with community guideline violations may have publishing restrictions.
Reauthorize Connection: TikTok tokens expire every 60 days. If publishing fails, disconnect and reconnect your account in Vexub settings.
YouTube Processing Delays
YouTube uploads may show 'Processing' for extended periods:
HD Processing: 1080p and 4K videos take longer to process. YouTube makes lower resolutions available first, then upgrades to HD once processing completes.
Peak Times: Uploads during peak hours (evenings in major markets) may process slower due to YouTube's server load.
Large Files: Longer videos take proportionally longer to process. A 10-minute 1080p video might take 15-30 minutes to fully process.
Instagram Reel Publishing Errors
Instagram has stricter requirements than other platforms:
Account Type: Verify your account is a Business or Creator account, not a personal account.
Facebook Page Connection: Ensure your Instagram Business account is still linked to your Facebook Page. Disconnections happen during Facebook security updates.
Video Specifications: Instagram Reels must be 9:16 aspect ratio, between 3-90 seconds, and under 1GB file size. Vexub automatically handles formatting, but corrupted exports may fail.
API Limits: Instagram limits the number of posts per hour. If you publish multiple Reels rapidly, subsequent uploads may be temporarily blocked.
Advanced Publishing Features
Beyond basic publishing, Vexub offers advanced features for creators managing multiple accounts and platforms:
Bulk Publishing for Content Series
If you've created multiple videos as part of a series, you can queue them for staggered publishing:
Select multiple completed projects from your Vexub dashboard.
Click Bulk Publish to open the multi-video publishing interface.
Set platform destinations and intervals between posts (e.g., publish one video every 4 hours).
Customize captions for each video individually, or use a template with variable fields.
Schedule the entire batch to publish over several days, maintaining consistent posting frequency without manual intervention.
This feature is particularly valuable when you've created multiple faceless videos in batch and want to maintain a consistent posting schedule.
Multi-Account Management
Content creators often manage multiple accounts across platforms. Vexub supports connecting multiple accounts for each platform:
Multiple TikTok Accounts: Connect up to 10 TikTok accounts and select which receives each video during publishing.
Multiple YouTube Channels: Manage all channels under your Google account, plus additional Google accounts for clients or brand channels.
Multiple Instagram Business Accounts: Connect different Instagram accounts linked to different Facebook Pages.
When publishing, you'll select which specific account receives the video. This allows operating multiple niche channels from a single Vexub workspace.
Analytics Integration
After publishing, Vexub displays basic analytics for published videos:
Publication Status: See which videos are live, processing, or scheduled across all platforms.
Platform Links: Direct links to each published video for easy sharing and monitoring.
Initial Performance: Basic view counts and engagement metrics pulled from platform APIs (updates every 24 hours).
For detailed analytics, Vexub links directly to each platform's native analytics dashboard where you can track comprehensive performance metrics.
Maximizing Cross-Platform Reach
Publishing the same video to multiple platforms extends reach, but each platform's algorithm and audience has different preferences. Smart creators adapt their strategy:
Test Different Thumbnails: YouTube thumbnails dramatically impact click-through rates. Test 2-3 variations using different frames or text overlays.
Platform-Specific Hashtags: Research trending hashtags on each platform separately. TikTok hashtags that go viral may have no impact on Instagram.
Adjust Video Length: If you have a 90-second Instagram Reel, trim it to 45 seconds for TikTok where shorter videos often perform better.
Stagger Publish Times: Post to TikTok at 7 AM, Instagram at 12 PM, and YouTube at 3 PM to maintain presence throughout the day.
Monitor Platform Performance: If your content consistently performs better on one platform, prioritize quality and frequency there while maintaining presence on others.
Vexub's direct publishing makes testing these strategies effortless. You can quickly iterate on what works without the technical friction of manual uploads.
Best Practices for Sustained Publishing Success
Consistent, quality publishing drives long-term channel growth. These practices help maintain momentum:
Maintain Brand Consistency: Use consistent caption structures, intro/outro elements, and visual styles across platforms so your content is immediately recognizable.
Build Publishing Templates: Save caption templates for different content types (tutorials, trending topics, storytelling) to speed up the publishing process.
Schedule Strategic Breaks: Queue 3-5 videos before taking time off to maintain your posting schedule during vacations or creative breaks.
Batch Creation and Publishing: Create multiple videos in one session, then schedule them across the week. This is more efficient than daily creation and publishing.
Respond to Comments Quickly: Early engagement signals platform algorithms that your content is valuable. Set aside time after publishing to respond to the first wave of comments.
The combination of AI-powered video creation and direct publishing through Vexub creates a sustainable content workflow that scales with your audience growth.
