A/V Calculators & Tools
A suite of precision tools for encoders, home theater enthusiasts, and archivists.
1. Bitrate from File Size
Calculate average overall bitrate based on target file size and duration.
2. File Size Estimator
Estimate final file size based on video+audio bitrate.
3. Aspect Ratio Identifier
4. SMPTE Viewing Distance
Ideal viewing distance for a 40-degree field of view (Cinema standard).
5. Subtitle Framerate Sync
Calculate new timestamp when converting subtitles between framerates (e.g. NTSC to PAL).
6. Speaker Delay (Distance)
Calculate the audio delay needed (in ms) for speakers placed further away.
7. Network Streaming Bandwidth
Calculate true network requirement including TCP/IP overhead.
8. Total Frame Count
9. Nit to PQ (ST.2084) Converter
Converts absolute luminance (nits) to a PQ signal value (0.0 to 1.0).
