Questions & answers
What does Video Cover Crop Planner calculate?
Calculate source crop dimensions for filling a target frame without bars.
Which units should I enter?
Source width uses pixels. Source height uses pixels. Target width uses pixels. Target height uses pixels. Convert values to these units before calculating.
Which formula does it use?
Cover scale = max(target width/source width, target height/source height); centered crop is assumed.
What does the included example show?
Source width: 1920 pixels; Source height: 1080 pixels; Target width: 1080 pixels; Target height: 1920 pixels. Result: Source crop width · pixels = 607.5; Source crop height · pixels = 1080; Source crop left · pixels = 656.25; Source crop top · pixels = 0; Retained source area · percent = 31.640625.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
