Videography

Combine local audio with a still image or solid color to create a verified MP4 in landscape, square or portrait format without uploading media.

Calculate near and far focus limits, total depth of field and hyperfocal distance, with optional blur tolerance, scene checks and setup comparison.

Calculate camera field width, height and angles from sensor size, focal length and distance, with optional target-fit checks and complete lens sweeps.

Plan golden and blue hour windows for a location and date with custom sun-angle boundaries, ready-by times, direction and horizon cautions.

Match framing across camera formats through exact focal length and depth-of-field look, with crop adjustments and a practical lens choice.

Calculate the external ND stops needed for a metered scene, then compare fixed, stacked or variable filters for stills and video settings.

Calculate time-lapse frames, interval, clip length or shoot duration, with optional storage, battery, exposure and scheduling checks.

Calculate frame-accurate timecode spans with drop-frame validation and endpoint rules, then add 24-hour wrap or pull handles when needed.

Extract one audio track from a local video as compatible MP3, editable WAV, or copied original packets with post-conversion verification.

Plan video storage from bitrate and recording duration, including multiple cameras and copies plus headroom and whole-drive capacity checks.

Build a one-day video call sheet with staggered crew calls, schedule conflict checks and calendar-ready events for the production day.

Compress a local video into a smaller MP4 while balancing picture and audio bitrate, then verify playback and measured savings before download.

Crop a video to a fixed rectangle or delivery aspect ratio in your browser, verify the playable MP4, and review how much frame area remains.

Convert a local video to MP4 or WebM while preserving compatible streams and verifying its codecs, dimensions and playback before download.

Extract one frame or a timed image sequence from a local video, then compare requested and decoded times before downloading the result.

Join local video clips into MP4 or WebM, normalize frame and sound handling, verify every join, and keep source files in your browser.

Inspect one local video for container and stream evidence, with bounded file reads plus clear warnings for sampled or missing metadata.

Resize a local video to exact even dimensions with whole-frame fit or centered crop, optional upscaling and audio control in a verified MP4.

Change a local video's speed from 0.25× to 4× in your browser, preview the duration, and choose tape-style retimed audio or a muted MP4.

Trim a local video to a reviewed interval, preview the playable clip, and keep the source file in your browser instead of uploading it.

Add a text or logo watermark to every video frame in your browser, preview its placement, and download a re-encoded MP4 with audio when supported.

Turn a short video clip into an animated GIF in your browser with adjustable timing, dimensions and frame rate plus color and looping controls.
