A practical guide to audio & video workflows
The best tool is the one that matches the input, decision and destination—not simply the broadest label.
Know the difference between a container and a codec
A filename extension often identifies a container, while codecs describe how audio or video is encoded inside it. Conversion choices affect compatibility, quality, processing time and file size. Check the destination platform and preserve the source before transcoding.
Use compression for a defined delivery target
Resolution, frame rate, bitrate, duration and content complexity all influence size and quality. Lowering one setting can solve a limit while damaging motion or text. Compare the result at normal playback size and listen for distortion rather than relying on a size figure alone.
Treat transcripts and subtitles as editorial material
Speech recognition and subtitle conversion can accelerate a workflow, but timing, names, punctuation and speaker changes need review. Keep subtitle text synchronized, use a supported encoding and add captions that serve comprehension rather than merely duplicating noisy automatic output.

Helpful answers
Audio & Video questions
Clear guidance for choosing and using the catalogue responsibly.
What is the difference between a media container and codec?
A container packages streams and metadata; codecs encode the audio or video streams inside it.
Does conversion improve audio or video quality?
No. Re-encoding can preserve or reduce perceived quality but cannot recreate detail missing from the source.
How can I make a video smaller?
Adjust codec, bitrate, resolution or frame rate according to the delivery target, then review quality and compatibility.
What is the difference between SRT and VTT?
Both store timed text; WebVTT supports web-focused features and syntax that differ from the simpler SRT format.
How accurate is speech-to-text?
Accuracy varies with language, accents, noise, microphones, overlapping speech and specialized vocabulary.
What does bitrate represent?
Bitrate is the amount of encoded data used per unit of time and is one factor affecting size and quality.
Can metadata reveal private information?
It can contain device, software, time or descriptive fields. Review metadata before public distribution when privacy matters.
Do I need permission to process media?
Yes. Use media you own or are authorized to transform, download, transcribe or redistribute.
