Guidelines for Media Settings on Social Media Platforms

Getting your images and videos to look their best across every platform starts with knowing the requirements for each one. Each social network has its own specifications, and when you are publishing the same post to multiple platforms at once, it is important to follow the most restrictive guidelines in the group to make sure your content publishes correctly everywhere.

Image Publishing Guidelines

Each platform has its own recommended image dimensions, aspect ratios, and file size limits. Refer to the guidelines for each platform before uploading to make sure your images display as intended.

Video Publishing Guidelines

• Supported video formats in Eclincher are MP4, MOV, and AVI
• All uploaded videos are converted to MP4 format encoded with H.264, with a maximum resolution of 1920x1080 pixels (Full HD) and a maximum frame rate of 30 fps
• Larger files may be compressed to meet platform requirements, though the impact on visual quality is kept to a minimum

Refer to the per-platform video guidelines for minimum and maximum file sizes, aspect ratios, and duration limits before scheduling your video content.

Additional Publishing Features

To help you manage content across multiple channels, here is a breakdown of three key Eclincher features related to media publishing.

1. Character Limitation
2. Link Attachment and Scraping
3. Selecting Images from a Link

Now, let's review each feature in detail:

1. Character Limitation

Every social platform has its own character limit for post text, and those limits vary quite a bit from one platform to the next.

• When creating a post for multiple platforms at the same time, Eclincher applies the lowest character limit among the selected platforms
• The remaining character count is displayed in the post editor so you always know where you stand

• For X Premium accounts: If the verified badge (blue checkmark) is not showing next to your profile on the Manage Accounts page, select Renew Token until the badge appears. This updates the 25,000 character limit in the post editor. If the badge still does not appear after renewing, reach out to the Support Team.

2. Link Attachment and Scraping

• When you add a link to your post, Eclincher automatically scrapes the linked page to pull in any available preview images.
• These images appear in the Post Preview window so you can see how the post will look before it goes live
• It is worth reviewing the preview each time, as some websites do not properly stage images for external scraping, which can result in a missing or incorrect preview image

3. Selecting Images from a Link

If the linked page contains more than one image, you are not locked into the default preview image that Eclincher pulls in.

• Click the Select Images from Link button to open a pop-up window showing all available images from that link
• Select the image or images you prefer and click Done
• The default scraped image will be replaced with your selection
• You can also reorder multiple images by dragging and dropping them into your preferred sequence

• You can also reorder the images by dragging and dropping them.

Quick FAQs

• What happens if my image does not meet the minimum size for a platform? Some platforms, like Instagram, will automatically enlarge undersized images, which can reduce image quality. Always upload at the recommended resolution for the best result.
• Can I upload a video in AVI format? Yes, AVI is supported. Eclincher will convert it to MP4 during processing.
• Why is my link preview image not showing up? Some websites restrict image scraping for third-party tools. If the preview is missing or incorrect, use the Select Images from Link option to manually choose an image, or upload one directly to the post.
• What if I am posting to platforms with very different character limits? Eclincher will apply the lowest limit among your selected platforms. If you need a longer post for specific platforms, consider creating separate posts tailored to each one.
