A 60-second Reel cut from a 3-minute raw clip
Trimming dead air and false starts from a 3-minute raw recording down to a tight 60-second Reel, with the hook in the first 2 seconds, is a typical, achievable edit in CapCut in well under 15 minutes.
Video editor online? Not here, on purpose
Looking for a video editor online? Real video trimming and cropping without a video codec library is not honestly buildable as a lightweight browser tool, so instead of a fake "editor" that cannot actually cut a video, this page covers what matters most: the right aspect ratio per platform (vertical 9:16 for Stories/Reels/Shorts, square or 16:9 for feed and long-form), where to place your hook, and real free tools — CapCut and DaVinci Resolve — that can do the actual editing.
How to edit a video for social media
- Pick the right aspect ratio first. Shoot or crop to 1080×1920 (9:16) vertical for Stories, Reels, TikTok and Shorts; 1080×1080 square or 16:9 landscape for feed posts and long-form YouTube.
- Cut straight to the hook. Trim any slow intro or brand bumper so the first 1-3 seconds show the most interesting moment, since that decides whether a scrolling viewer keeps watching.
- Remove dead air aggressively. Cut pauses, false starts and filler words — a tighter edit almost always outperforms a longer one with the same content.
- Edit in a real free tool. Use CapCut for short vertical social video or DaVinci Resolve for more advanced desktop editing — both are genuinely free.
- Export as MP4 at the right aspect ratio. Export the finished edit as MP4 at your target platform's aspect ratio before scheduling, since SkedCast does not re-encode or crop video on upload.
Worked examples
One horizontal recording, three exports
A single screen recording can be re-cropped in a real editor into a 1080×1920 vertical Reel, a 1080×1080 square feed post, and a 1920×1080 landscape YouTube upload — three exports from one source clip.
Video editor online: FAQ
- Why doesn’t SkedCast have a built-in video trimmer?
- Real trimming and re-encoding needs a video codec library too heavy to run in a browser without a significant new dependency — this page covers the practical guidance and real free tools that can do it instead.
- What aspect ratio should I use for a Reel or TikTok?
- Vertical 9:16, ideally 1080×1920 pixels — shoot vertical from the start rather than cropping a horizontal video afterward.
- How long should the intro be before the hook?
- As close to zero as possible — the first 1-3 seconds decide whether a scrolling viewer keeps watching, so cut straight to the most interesting moment.
- What is a good free video editor?
- CapCut for short vertical social video (free, desktop and mobile, built-in captions), or DaVinci Resolve for more advanced desktop editing — both are genuinely free, not free trials.
- Does SkedCast re-encode my video when I upload it?
- No — SkedCast schedules and publishes the file you upload as exported from your editor, so get the format, aspect ratio and trim right before uploading.
- Will SkedCast add a real in-browser editor later?
- Only if it can be done honestly without a heavy new codec dependency — for now, a real desktop editor is the accurate recommendation.
