AI Video Formats and Export: A Simple Guide

Export the wrong format, and your video looks bad. It may get cropped or blurry. This guide helps you understand the basics so you can pick the right setup with ease.

We cover file types, aspect ratios, resolution, codecs, bitrates, and platform-specific optimizations. By the end, you will know how to optimize AI-generated videos for different platforms.

What is a video format?

A video format is how your file is packaged. It bundles the picture and sound into one file. The file type shows in the name, like video.mp4.

MP4 (MPEG-4 Part 14) is the most common video format. Nearly every platform accepts it. It plays on phones, laptops, and TVs. Most tools export MP4 by default because of its wide compatibility.

Other formats exist too, like MOV and WEBM. But you rarely need them for social media platforms. Stick with MP4 for most uploads. It just works.

Kyndrify exports standard MP4 video. So your files stay easy to share. You can upload them almost anywhere.

What are the technical differences between MP4, MOV, and WEBM?

MP4 (MPEG-4 Part 14): Uses H.264 codec by default, widely compatible, good for streaming and social media.
MOV (QuickTime File Format): Often uses ProRes or H.264 codec, preferred for editing due to high quality but larger file sizes.
WEBM (WebM Project): Uses VP8 or VP9 codecs, designed for web streaming, smaller file sizes but less compatible with some platforms.

What is video aspect ratio?

Aspect ratio is the shape of your video. It compares width to height. Each platform prefers a certain shape.

Here are the three shapes you will use most:

9:16 (vertical): Tall and narrow. Best for phones held upright.
1:1 (square): Equal width and height. Good for feeds.
16:9 (widescreen): Wide and short. Best for landscape video.

Pick the shape your platform wants. A wrong shape gets cropped or boxed in. That wastes screen space and looks off.

Kyndrify supports aspect ratios for different platforms. You can make vertical, square, or widescreen video. Match the ratio to where you post.

Which aspect ratio does each platform need?

Use this table as a quick guide. It maps each platform to a common shape.

Platform	Best aspect ratio	Shape
YouTube	16:9	Widescreen
YouTube Shorts	9:16	Vertical
TikTok	9:16	Vertical
Instagram Reels	9:16	Vertical
Instagram feed	1:1 or 9:16	Square or vertical
LinkedIn feed	1:1 or 16:9	Square or wide
Email	16:9	Widescreen

These are common picks, not strict rules. Platforms may accept other shapes. But these give the best fit.

What does resolution mean?

Resolution is how sharp your video looks. It counts the pixels on screen. More pixels means a clearer picture.

1080p (Full HD) is a common, sharp resolution. It is also called Full HD. It looks great on phones and most screens.

Kyndrify's Plus plan lists talking-head video up to 1080p. Other plans have their own output scopes. Check the pricing page for what each plan includes.

You do not always need higher than 1080p. Bigger files take longer to upload. For social video, 1080p is plenty.

What are codecs and bitrates?

Codecs compress and decompress video data. Common codecs include H.264 (used in MP4), VP9 (used in WEBM), and ProRes (used in MOV).

Bitrate measures how much data is processed per second of video. Higher bitrates mean better quality but larger file sizes.

H.264: Widely compatible, good for streaming, recommended bitrate 5 Mbps for 1080p.
VP9: Better compression than H.264, recommended bitrate 3 Mbps for 1080p.
ProRes: High quality but large file sizes, used mainly for editing.

Do I need captions or subtitle files?

Yes, captions help a lot. Many people watch with sound off. Captions keep your message clear.

There are two main ways to add them:

Burned-in captions: Text baked into the video. Always visible. No extra file needed.
Subtitle files: A separate file, like .srt. Viewers can turn it on or off.

Burned-in captions are simple and reliable. They show on every platform the same way. This is the easy choice for social clips.

Kyndrify's current product pages do not document a built-in captioning feature. You may need another tool for captions. Check the product page for the latest features.

How do I pick the right export per platform?

Start with where you will post. Then match the shape and add captions. Keep these quick rules in mind.

YouTube: Export 16:9 widescreen at 1080p using H.264 codec. Add burned-in captions for clarity.
TikTok: Export 9:16 vertical at 1080p using H.264 codec. Captions help reach.
Instagram Reels: Export 9:16 vertical at 1080p using H.264 codec. Add captions.
Instagram feed: Use 1:1 square or 9:16 vertical with H.264 codec. Captions still help.
LinkedIn: Use 1:1 square or 16:9 wide with H.264 codec. Captions boost views.
Email: Use 16:9 widescreen with H.264 codec. Link out to a hosted video.

Export MP4 in every case. It uploads cleanly to all of these. One file type covers your whole plan.

Frequently asked questions

What is the best video format for social media?

MP4 is the best choice for social media. Nearly every platform accepts it. It plays on almost any device. Export MP4 unless a platform asks for something else.

What aspect ratio should I use for TikTok and Reels?

Use 9:16 vertical for both. This fills the phone screen fully. It is the standard shape for short video. A vertical clip looks native in these feeds.

Is 1080p good enough for video?

Yes, 1080p is plenty for social video. It is sharp and clean on phones. It also uploads faster than larger files. Most viewers will not notice a difference.

Should captions be burned in or a separate file?

Burned-in captions are simpler for social clips. They show the same way on every platform. Subtitle files let viewers toggle text on or off. For quick posts, burned-in works best.

Can I make one video for many platforms?

Yes, but adjust the shape for each. Export a vertical version for TikTok and Reels. Export a wide version for YouTube. Keep the message the same across all.
