Frequently asked questions
What can I figure out with the Video calculators?
You can plan marathon viewing sessions for Star Wars, the Oscars, or any TV series; calculate how long a binge will take at different daily watch limits; convert frame counts and timecodes for video editing; size video files with the Video Bitrate Calculator; and find the exact physical dimensions of any TV screen.
Are the timecode and bitrate calculations accurate?
The Timecode Calculator uses standard SMPTE frame-rate math, and the Video Bitrate Calculator follows established encoding guidelines. Binge and marathon durations pull from published episode runtimes. Results are reliable estimates — always double-check official runtimes for titles that vary by region or streaming platform before committing to a schedule.
Does the site save any of my viewing preferences or video project details?
