Always keep the original
A small habit that saves headaches later. This guide shows the safe AI Subtitle Generator workflow that always preserves the source file before any edit.
If you've ended up here, you have a video and a specific job: preserving the original. The defaults most software ships with aren't tuned for that — they're tuned for "archive everything at maximum quality," which is the opposite of what you need now.

Why preserving the original needs different settings
A video for preserving the original optimises for things the original video doesn't care about: small enough to upload quickly, compatible with whatever software the recipient is using, and free of embedded metadata that could leak personal information. The defaults give you the opposite — large, high-quality, metadata-rich. Useful for some jobs, wrong for this one.

What to verify before sending
Quick check-list once AI Subtitle Generator finishes:
- Open the result. Make sure it looks right at the size the recipient will actually see it.
- Check the file size. Match it against the limit you're targeting.
- Confirm the file extension. Sometimes you need to rename — for example, a recipient who expects
.jpgwon't necessarily accept.jpeg. - Send a test to yourself first. Open the test on the same device the recipient will use, if you can.
Frequently asked questions
Should I rename the result?
Often yes. Recruiters and portals often pre-filter by filename patterns; a clean, predictable name (e.g. "FirstName_LastName_Resume.pdf") is worth the 10 seconds.
Can I undo the compression later?
No — compression is one-way. Always keep the original video archived somewhere, and treat the compressed version as a send-only copy.
Will AI Subtitle Generator work for a batch of videos?
Yes — drop multiple files at once. All of them get the same preserving the original settings applied, then downloaded as a folder.
Does compressing a video make it look unprofessional for preserving the original?
Not when done right. Sensible compression at the "balanced" preset produces output indistinguishable from the original to the human eye, even at half the size.
