A processed video clip ready for export
Basic familiarity with video file formats (MP4, MOV)

Steps

Understand why compression matters

Every social platform recompresses your video when you upload it. If you upload a poorly compressed file, the platform's re-encoding compounds the quality loss, resulting in blurry, blocky, or washed-out clips. The goal is to export a file that is already optimized — high enough quality that the platform's compression doesn't degrade it noticeably, but small enough to upload quickly and reliably.

Tip: Think of it as giving the platform a 'clean' file to work with. The better your starting point, the better the final result after platform re-encoding.

Learn the key compression settings

The three most important settings for video compression are: (1) Codec — H.264 is the safest, most widely supported codec for social media. H.265 (HEVC) offers better compression but has inconsistent platform support. (2) Bitrate — this controls how much data is used per second of video. Higher bitrate = higher quality but larger files. For social clips, 8–15 Mbps for 1080p is a good target. (3) Resolution — export at the native resolution of your clip. Upscaling adds file size without adding quality.

Tip: When in doubt, H.264 at 1080p and around 10 Mbps is a universally safe export setting for short-form social clips.

Match your resolution to the platform and aspect ratio

Each platform and aspect ratio has an ideal resolution. For vertical (9:16) content on TikTok, Reels, and Shorts: 1080x1920 is the standard. For content on LinkedIn and Instagram: 1080x1080. For on YouTube: 1920x1080. Exporting at a higher resolution than the platform supports wastes file size without any visible benefit.

Tip: OpenClip exports clips pre-formatted for each aspect ratio, so you're already starting from the right dimensions.

Set the right frame rate

For social media clips, 30fps (frames per second) is the standard. 60fps is supported by some platforms and looks smoother for action-heavy content, but it roughly doubles file size. For talking head clips, interviews, and podcast highlights — which make up the majority of repurposed content — 30fps is ideal. Match your export frame rate to your source video where possible.

Tip: Avoid converting between frame rates if you can — e.g., taking a 29.97fps source and exporting at 30fps can cause minor sync issues. Keep it consistent.

Optimize audio compression alongside video

Audio is often overlooked in compression. For social clips, AAC audio codec at 192 kbps stereo is the widely recommended setting. This produces clean, clear audio at a small file size contribution. Avoid very low bitrates (under 128 kbps) as they introduce audible artifacts, especially in voice content.

Tip: If your source audio has background noise, address it before compression — compression amplifies audio artifacts, it doesn't hide them.

Export from OpenClip and verify the output

OpenClip exports clips as MP4 files using settings optimized for social platform delivery. After exporting, do a quick quality check: play the clip at full screen and look for blockiness, blurring, or compression artifacts. Check the file size — a 60-second vertical clip at 1080x1920 should typically be between 30–80 MB depending on visual complexity. If a clip is unexpectedly large, check if your source video is unusually high bitrate.

Tip: Upload a test clip to your target platform before a campaign goes live. Some platforms display videos differently in-feed vs. full-screen, so verify both views.

Platform-specific compression tips

TikTok: Upload at 1080x1920, H.264, 30fps. TikTok re-encodes aggressively, so start with the highest quality export you can. Instagram Reels: Same as TikTok — 1080x1920. Instagram compresses heavily, especially in stories. YouTube Shorts: YouTube is more forgiving with compression. 1080x1920 at H.264 works well. LinkedIn: 1080x1080 (square) or 1920x1080 (horizontal) — LinkedIn has more lenient compression. Twitter/X: Keep files under 512 MB and under 2 minutes 20 seconds. 1080x1080 or 1280x720 are safe choices.

Tip: For platforms that compress heavily (TikTok, Instagram), exporting at a slightly higher bitrate than you think you need gives the platform more data to work with during its re-encode.

Frequently Asked Questions

OpenClip exports clips as H.264 MP4 files, which is the most widely supported format across all major social platforms including TikTok, Instagram, YouTube, LinkedIn, and Twitter/X.

Both TikTok and Instagram re-compress videos after upload. To minimize quality loss, export at the highest practical quality (1080p, H.264, 10+ Mbps) so the platform has clean source data to work with. Uploading over WiFi rather than mobile data can also help maintain quality.

Export YouTube Shorts at 1080x1920 (vertical 9:16) at 30fps. YouTube supports higher resolutions, but 1080p is the practical sweet spot for file size vs. quality on short-form content.

A well-compressed 60-second vertical clip at 1080x1920 should typically be between 30–80 MB, depending on visual complexity (fast motion = larger file, talking head = smaller file). Files significantly larger than this may cause slow uploads or trigger aggressive platform re-compression.

Yes — 60fps roughly doubles the file size compared to 30fps at the same quality settings. For most social media content (talking heads, interviews, podcast clips), 30fps is ideal and indistinguishable from 60fps in practice.

No — upload the highest quality source file you have. OpenClip works best with high-quality input and handles the export optimization for you. Compressing before upload reduces the quality ceiling for your final clips.

Resolution is the number of pixels in your video (e.g., 1080x1920). Bitrate is how much data is used per second to represent those pixels. You can have a high-resolution video with a low bitrate — it will look blocky and compressed. Both need to be appropriate for good quality output.

Absolutely — clear audio is arguably more important than video quality on short-form social content. Export with AAC audio at 192 kbps. If your source audio is noisy or unclear, address that before exporting, as compression won't improve audio quality.
