Why keyword density stopped mattering, and what to measure instead
A ranking factor that died twenty years ago, what the word count still usefully reveals about a draft, and the five signals worth watching in its place.

Resizing: both numbers are used exactly as entered
There is no aspect lock, so mismatched dimensions distort without warning. The one line of arithmetic that prevents it, why enlarging cannot add detail, and the sizes destinations actually use.
Read moreWhat a good summary keeps, and what it is safe to drop
Extraction and abstraction fail in opposite directions. How sentence ranking works, which documents defeat it, and the check that catches a summary saying more than its source.
Read moreWhy Title Case here capitalises words like “of” and “the”
The rule applied is purely mechanical — capitalise every whitespace-separated run — not the editorial convention most style guides actually follow. Why snake_case drops accented characters rather than converting them, and why converting to uppercase here is permanent, unlike a CSS styling choice.

Why trimming a video always re-encodes it, even for a simple cut
A file can only start at a keyframe, so landing the cut on the exact second asked for means re-encoding rather than copying. Why a ten-second trim from an hour-long file still decodes the whole hour of audio, and why timestamps are rebased to zero.
Read moreWhy these captions are burned into the picture, not a track you can turn off
Most social platforms never show a separate subtitle track at all, which is the real reason the words get drawn onto the frames instead. Why every line gets an outline whether you ask for one or not, and what a caption running past the end of the video is actually telling you.
Read moreWhy Video Studio composites once instead of chaining six tools
Six single-purpose tools chained together means six decode-and-encode passes and six generations of quality loss. How captions get remapped across a cut, why the logo reaches the intro but captions do not, and where the sound can go missing.
Read moreWhat actually limits how many clips Video Splitter can make
It is the total output held in memory before the ZIP is written, not the length of the source video. Fill-and-crop versus blurred fill for turning widescreen into vertical, why a two-second remainder gets dropped, and how to pick a clip length.
Read moreWhy there is no delete button — you mark what to keep
Removing a middle part means marking the section before it and the section after it, not deleting anything. Why the result is one continuous file rather than several stitched together, and how this differs from both the trimmer and the merger.
Read moreWhy this replaces a video’s sound instead of mixing into it
No levels, no ducking, because there is only ever one audio source in the result. What happens when a track runs longer or shorter than the video, why the real risk here is copyright rather than audio quality, and why Firefox and desktop Linux cannot use this tool at all.
