Step-by-step: create Shorts with Munch
Step 1: Create a new project
On the projects page, click the + button in the middle or Create New at the top right.
Step 2: Choose your platforms
Select up to two platforms (for example YouTube Shorts and TikTok) and click Next. Munch formats the clips for them.
Step 3: Add your video
Paste a link or upload the file from your computer, then click Next.
If you paste a link, the video must be public. Only use videos you own or have rights to.
Step 4: Pick a subtitle style
Choose a subtitle template and click Next. Bold, high-contrast captions work best because most short-form viewers watch with the sound off.
Step 5: Describe the video and start
Name the project, choose the option that best describes your source video under “Describe your source video”, and either set a clip length or let Munch choose lengths for your platforms. Click Munch It!.
Processing runs in the background. Munch emails you when the clips are ready.
Step 6: Review and pick the best clips
Open the project and scroll to the generated clips. Hover over a thumbnail and click the eye icon to preview. Use the aspect-ratio control next to play/pause to check how the clip looks in different formats.
Pick clips that make sense without context and hook the viewer in the first 2 seconds: a bold claim, a question or a surprising number.
Step 7: Edit captions and cropping
Click the pen icon or Edit. Use the timeline to trim the clip, click any word to correct it, and drag subtitles to reposition them. Turn on manual cropping in the top menu if auto-cropping cuts off the speaker. The Magic Posts section drafts post captions for each platform, which you can edit.
Step 8: Export or publish
Click Export in the top right to download the clip or publish it to your connected social accounts.
Posting plan for one long video
| Day | Post | Tip |
|---|---|---|
| Day 1 | Full video on YouTube | Add chapters and a strong thumbnail |
| Day 2 | Clip 1: the strongest hook | Link to the full video in comments or description |
| Day 3 | Clip 2: a quick tip | Ask a question to drive comments |
| Day 4 | Clip 3: a surprising fact | Use a bold first caption line |
| Day 5 | Clip 4: a story or result | Pin a comment pointing to the full video |
Watch which clips get the most views and replays, then make more long videos on those topics.
