Find the Highlights for a Short-Form Video

A short-form video editor should save you from scrubbing a long recording to find the part worth posting. Upload a video or paste a link and ScreenApp’s AI highlights and automatic bookmarks, so you can jump to the moments worth clipping instead of watching the whole thing back.

From there, you trim recordings to the exact start and end point, then download the clip or share a link to it. If the clip needs to be cropped to vertical for TikTok, Reels, or Shorts, run it through the vertical video converter afterwards, which crops to 9:16, 1:1, or 4:5.

How to Edit a Short-Form Video

  1. Upload or import the video: Add a file in MP4, M4V, MOV, AVI, WEBM, MKV, FLV, TS, MTS, M2TS, 3GP, 3GPP, 3G2, WMV, ASF, VOB, OGV, RM, RMVB, MPG, MPEG, M2V, F4V, MXF, or paste a YouTube, Vimeo or YouTube, Vimeo and direct media links link. Processing starts once the video is in your library.
  2. Let AI find the highlights: AI highlights and automatic bookmarks across the recording, so you can open a bookmark instead of dragging the playhead back and forth.
  3. Trim, then crop for the platform: Use the trim tool to set the exact start and end point, then download the clip on a paid plan or share the link. Send the trimmed clip through the vertical video converter if you need it cropped to a vertical frame.

Accuracy of the transcript and the highlights depends on the audio: a clean single-speaker recording works better than a noisy room with several people talking over each other. See how we measure accuracy.

Who Uses a Short-Form Video Editor

Content creators upload a long stream or interview and use the highlights to find the moments worth pulling into TikToks, Reels, and Shorts, instead of watching the whole recording back to spot them.

Marketing teams turn a webinar or product demo into a short clip for a landing page or a social post, trimmed to the one point that matters.

Podcasters with video episodes search the transcript for the exchange they remember and trim it into a clip to post alongside the full episode.

Educators pull the explanation a student asked about out of a longer lecture recording, instead of re-recording the whole thing.

Small businesses cut a promotional clip or a customer story out of longer footage to post on social media, without hiring a video editor.
