Show HN: Edit videos faster by automatically removing silences
Our team is filled with technologists and creators, and when we
record and edit videos, 80% of the time is spent chopping up the
video, removing silences, and picking the right takes. So we
decided to build a tool that did that for you -- or at least get
you there most of the way! Our initial implementation is somewhat
naive and uses a user configurable silence threshold that just
reads in volume levels. In the future, we'd like to use a
frequency-based approach that focuses on the human voice. We're
also open to ideas, so let us know if you have any!

| one spot all in the browser

| shahahmed wrote:
| i think there is overlap with descript, however i do think
| descript is transcript-first, and they focus on that level of

| middle, but I think having a robust timeline is important for
| video editing
