Social media image sizes for every platform
Instagram's help page now allows 3:4, YouTube's recommended thumbnail is 4K, and TikTok publishes almost nothing. Here are the numbers each platform actually documents, and where they leave you guessing.
7 minute readHow to convert landscape video to vertical
A full-height 9:16 crop of a 1920x1080 frame is 607 pixels wide. Which third of the picture you keep, and whether it is allowed to move, is the entire job.
8 minute readHow to crop video for Instagram
Your reel plays at 9:16 and previews on your profile inside a 3:4 rectangle. Anything you centred for one gets cut by the other, which is why so many covers lose their own headline.
7 minute readHow to cross-post your videos without watermarks
Instagram says a reel carrying another app's logo still reaches your followers but is held out of recommendations. That mark almost always arrives from one step: downloading your own video back out of the app you posted it to.
7 minute readSRT vs VTT: the subtitle format differences that matter
One uses commas, the other periods, and only one of them can position text on screen. Here is what actually separates SRT from WebVTT, and which one your platform wants.
7 minute readHow to remove background noise from video
Most noise problems are really signal problems. Here is the order to work in, why heavy denoising can sound worse than the noise it removed, and when to leave the floor alone.
8 minute readHow to add text to video
Most on-screen text fails for one of three reasons: it sits where the app draws a button, it is too thin to read on a phone, or it leaves before anyone finishes it.
8 minute readVideo SEO: ranking on YouTube, and getting into Google results
Google will not index your video until the page it sits on is already ranking, and YouTube never asks you for schema markup. Two systems, two checklists, almost no overlap.
8 minute readDo YouTube tags matter? What YouTube actually says
YouTube's own help page says tags play a minimal role in discovery and are mainly useful for common misspellings. An entire industry of tag tools implies otherwise.
7 minute readYouTube chapters: the exact rules, and what they change
Three rules decide whether your chapters appear at all. Here they are precisely, plus what chapters do for YouTube search and Google key moments — and what they do not do.
7 minute readHow long should a YouTube video be?
Eight minutes is a real revenue threshold and a terrible content target. Here is what the length studies found, what YouTube's own rules say, and how to pick a number for your channel.

WCAG puts a hard number on flashing content and on text contrast. Platform docs tell you where auto-captions fall short. Here is the whole checklist, with the thresholds attached.

Gain is not volume, a LUT is not a grade, and a container is not a codec. Here are the words that stop beginners, grouped by the part of the job where you actually hit them.
8 minute readHow to write alt text people can actually use

8 minute readHow to make a video loop seamlessly
A clean loop is a craft problem with a known solution. The claim that loops win you reach is a different problem entirely, and the evidence behind it is far thinner than the advice suggests.
7 minute readA video asset filing system you can still use in five years
