TRY IT HERE — TIMECODE TO FRAMES LIVE
Three tools, no setup
Each one opens instantly and works offline after the first load.
01
Convert timecode to frames and frames back to timecode at any frame rate, with a frame duration reference for 23.976 through 60 fps.
02
Estimate export file size from bitrate and duration, or calculate the exact target bitrate needed to fit Discord, Slack, and email upload limits.
03
Calculate exact frame counts and cut intervals for any musical tempo across 24, 25, 30, and 60 fps with tap tempo and marker export.
04
Calculate memory card needs and storage footprints for Apple ProRes, Blackmagic RAW, Sony XAVC, and mirrorless codecs across multi-camera shoots.
05
Convert SMPTE timecode across 23.976, 24, 25, 29.97 DF/NDF, and 59.94 fps with drop-frame math and timeline drift analysis.
06
Scale width and height to 16:9, 9:16, 4:5, 2.39:1 or a custom ratio, with pixel dimensions at 1080p and 4K.
07
Trim, crop, caption and convert a short clip to GIF or WebM in the browser — the file never leaves your device.
08
Extract a full-resolution still from any video frame and save it as PNG, WebP, or JPEG — frame-accurate, lossless, and never uploaded.
09
Pull the audio track out of a video in the browser — copied losslessly when possible, or converted to WAV, MP3, M4A or Opus.
10
Remove the audio track from a video without re-encoding it — the picture is copied untouched and the file never leaves your device.
11
Convert SRT, WebVTT, ASS and SSA subtitles into each other or into plain text, repair broken encodings, and see every problem the file has.
