about · how this works What is this? A specialized calculator for cropping anamorphic video content. Anamorphic video uses non-square pixels, which means stored dimensions differ from display dimensions. This tool calculates the correct crop parameters while accounting for the pixel aspect ratio. How to use Extract a frame from your 720×540 anamorphic video Load the frame using the drop zone above Enter your desired crop width Adjust X and Y offsets to position the crop region Copy the generated crop filter and use it in your FFmpeg command Background Anamorphic video (particularly NTSC DV) is stored at 720×480 or 720×540 pixels but displays at 4:3 (640×480) or 16:9 (854×480) depending on the pixel aspect ratio. When cropping, you need to account for the vertical squeeze. This tool uses an 8/9 vertical squeeze adjustment, appropriate for 4:3 DV content. Crop height is computed as width × 3/4 to maintain a 4:3 ratio, then × 8/9 to account for the anamorphic encoding. The "likely full filter" output includes bwdif deinterlacing (common for DV footage), the crop filter with adjustments, scaling back to 720×540, and setting the pixel aspect ratio to square (1:1) with setsar=1.
