From source file to delivery
Choose the original capture
Use the recorder’s saved video rather than a copy that has already passed through a messaging app. Make any necessary redactions before uploading.
Protect text before reducing dimensions
Try Quality mode first. If the result must fit a hard limit, switch to Target size and inspect whether small labels remain readable.
Review the busiest and smallest details
Check a dense spreadsheet or code window at normal viewing size, then watch rapid scrolling and listen for synchronization before sending the result.
The scene decides what to inspect
| Recording | Inspect first | Avoid this shortcut |
|---|---|---|
| Code or spreadsheet walkthrough | Small characters, punctuation and cell borders | Downscaling until the whole desktop fits a tiny preview |
| Slide narration | Slide labels and speech clarity | Judging quality only on a title slide |
| Gameplay or fast scrolling | Motion trails and blocky detail | Assuming a static-screen preset preserves fast movement |
A readable demonstration is not the same as a sharp thumbnail
A screen recording may contain almost no movement for several seconds, then a fast scroll across dozens of small labels. Checking only the first frame misses the part that is hardest to encode. Review the exact interaction the recipient needs to follow.
Resolution reduction can erase useful text even when the video still looks smooth. If you recorded a large monitor, consider a closer crop or a larger application zoom during your next recording. The compressor does not crop the existing recording or restore characters that were unreadable in the source.
OBS files and tutorial exports belong in one workflow
OBS is a recorder, not a guarantee of a particular compression need. Its output can contain a game, a static desktop or a camera scene. Match the review checklist to the content rather than creating a different encoding rule for the filename or recorder brand.
Keep the original capture for future edits. The sharing copy is for delivery, not a replacement for a master recording. For a strict limit, calculate the available bitrate from duration before repeatedly trying more aggressive settings.
Questions before you compress
Why did the screen recording become hard to read?
Small text can disappear when resolution or bitrate is reduced too far. Compare a detailed frame at the intended display size, then increase the target budget or avoid downscaling.
Does Quality mode guarantee a smaller file?
No. CRF aims at an encoding quality level, not a fixed size. An already efficient source can produce little saving or even a larger output.
Can this remove private notifications from the recording?
No. Redact or edit sensitive frames before uploading. Compression changes encoding; it is not a privacy redaction tool.

Have a strict size budget? Use the bitrate calculator. For source files near the upload ceiling, check the large video limits. Read the privacy policy before sending sensitive material.
