Record your screen from the terminal. Stop it with one key.

Records the full screen plus system audio and microphone, mixed into one track, as H.264/AAC MP4. Press s to stop, or set -d 30s to stop on a timer. Interval mode (-e 10s) splits a long recording into seamless, independently playable segments as it goes — a crash only costs the current segment.

$ vidcapture start                    # record until you press 's'
$ vidcapture start -d 30s             # stop automatically after 30 seconds
$ vidcapture start -e 10s             # split into 10-second segments
$ vidcapture start -o ./recordings/   # save into ./recordings/

Pulls a millisecond-precise range out of any existing video into a new file. The source is opened read-only and never modified. Re-encodes by default for a frame-accurate start; --fast stream-copies for a near-instant, keyframe-aligned cut.

$ vidcapture cut talk.mp4 --length 5s                       # first 5 seconds
$ vidcapture cut talk.mp4 --from 10s --to 25s               # 10s through 25s
$ vidcapture cut talk.mp4 --from 1m --length 1500ms --fast   # no re-encode

Draws timed text onto any existing video: each label appears for the span you give it and disappears again. Repeat -l for as many labels as you need, all in one pass. A label needs only its text and its window — it comes out white on a translucent band, readable over whatever is behind it.

$ vidcapture label talk.mp4 \
    -l "text=Intro,from=0s,to=1m32s,position=top" \
    -l "text=Setting up,from=1m32s,to=2m" \
    -l "text=Live demo,from=2m,length=90s,color=#ffcc00,size=48,background=black@0.7"

Each -l takes one label as comma-separated key=value pairs. To put a literal comma in the text, write \,. The result is written beside the source as talk_labeled.mp4; talk.mp4 is never modified.
