VidBitCalc is the all-in-one app for video encoding calculations.
Whether you work as a professional compressionist or convert your videos for YouTube or Instagram, you will use VidBitCalc every day.
VidBitCalc contains:
- the Bit Budget Calculator: enter the available disc space, the video duration, and the audio bitrate to calculate the appropriate video bit rate
- the File Size Calculator: enter the duration and bitrates of your video to calculate the resulting file size
- the Resolution Calculator: enter the aspect ratio of your video and the desired width or height to calculate the proper resolution
- the Traffic Calculator: enter the duration, bitrates, and viewers of your stream to calculate the needed bandwidth and resulting traffic
- the unique BPP Calculator uses bits per pixel to help you find the optimal bitrate for your video.*
* For web video encoded with modern codecs a bits per pixel value of around 0.1 should result in reasonable quality. For DVD-Video or Blu-ray, a bits per pixel value above 0.4 is common.
