CastCutCastCut › Clips for every platform
Podcast clips in every size you post
Find the moments worth posting once, then get each one in every shape your platforms want: vertical for Reels, TikTok and Shorts, 4:5 for the feed, square, and 16:9 for YouTube. Each is framed for its own shape and opens as its own project in your editor.
Pick the platforms, not the math
- 9:16 for Reels, TikTok and YouTube Shorts. Follows whoever is talking, up to 4K.
- 4:5 for the Instagram and Facebook feed, where portrait posts take up the most room.
- 1:1 square, for LinkedIn and anywhere a square post fits.
- 16:9 for YouTube and X, framed like the landscape edit, zooms included.
Tick as many as you post. Every moment comes out once per shape, and all the versions of a moment sit together in one event in Final Cut Pro, or as separate sequences in Premiere Pro and DaVinci Resolve.
Framed for each shape, not squashed
A square or 4:5 clip is not the vertical one with bars. CastCut crops each shape around the speaker's face, and uses their own camera when they have one. Footage from a 4:3 camera app fills a 16:9 clip instead of sitting between black bars.
Captions sized to fit
Every clip gets captions timed to its own cut, with shorter lines for tall and square shapes. They arrive as real captions you can restyle.
Moments worth posting
A local AI reads the whole conversation and ranks complete thoughts with a hook and a clean ending, best first. It all runs on your Mac: nothing is uploaded.
Questions
Can CastCut make square and 4:5 podcast clips?
Yes. Tick 1:1 square or 4:5 for the Instagram and Facebook feed, alongside 9:16 and 16:9. Each moment comes out once per shape, framed on the speaker.
Which sizes does CastCut export clips in?
9:16 (1080x1920) for Reels, TikTok and Shorts, 4:5 (1080x1350) for the feed, 1:1 (1080x1080) square and 16:9 for YouTube and X.
Do I have to crop each size myself?
No. Each shape is framed automatically around whoever is talking, and every version is a normal editable project you can adjust.
Does it work with Premiere Pro and DaVinci Resolve?
Yes. Premiere Pro gets every clip in one file; DaVinci Resolve gets one timeline file per clip and shape.
