How to make a youtube short from a podcast video clip
- Step 1Identify the exchange worth clipping — Find a self-contained 30–60 second moment — a hot take, a story, a back-and-forth. The formatter keeps the first 60 seconds, so this is what you'll put at the start.
- Step 2Trim the highlight to the front — Cut your range with lossless-trimmer — instant, no re-encode — so the formatter's
-t 60window starts on the exchange, not the episode intro. - Step 3Decide single-cam or two-cam framing — If your clip is a single host centered in frame, the center crop works directly. If it's a side-by-side two-shot, crop each speaker first with video-cropper — the center crop would keep the empty gap between them.
- Step 4Drop the clip onto the formatter — MP4, MOV, MKV, WebM, AVI, M4V, or TS. Loads into the in-browser FFmpeg.wasm filesystem — no upload. Size cap is 1 GB (Free) to 100 GB (Pro-media/Developer).
- Step 5Run the reframe + format pass — JAD center-crops to 9:16, scales to 1080×1920 with Lanczos, applies
-t 60, and encodes H.264 + AAC 128 kbps — the dialogue track is preserved cleanly. - Step 6Burn captions before publishing — Podcast Shorts live or die on captions — most plays are muted. Hardcode an SRT/VTT onto the 1080×1920 output with subtitle-burner, then upload.
Podcast cam layouts and the right reframe
The formatter's center crop suits some podcast setups and not others. Pick the tool that matches your cam layout.
| Cam layout | Center crop result | Recommended approach |
|---|---|---|
| Single host, centered | Host kept intact | youtube-shorts-formatter directly |
| Single guest, centered | Guest kept intact | youtube-shorts-formatter directly |
| Two-shot (host L + guest R) | Empty gap kept, both edges cropped | video-cropper per speaker, then format |
| Active-speaker switch (already cuts to one cam) | Whoever's centered is kept | youtube-shorts-formatter, if cam is centered |
| Quad grid (4 cams) | Center of grid kept (likely a seam) | Crop one cam first with video-cropper |

| Step | Tool | Purpose |
|---|---|---|
| Cut the highlight | lossless-trimmer | Pull the 30–60s exchange, lossless |
| Reframe one speaker (two-cam only) | video-cropper | Pick the 9:16 column over a speaker |
| Format to spec | youtube-shorts-formatter (this tool) | Center-crop + 1080×1920 + 60s |
| Burn captions | subtitle-burner | Sound-off readability |
| Mute a swear/segment (optional) | audio-mute-region | Bleep or silence a span |
Cookbook
Podcast-specific reframes. Center-crop math from the filter chain, plus the two-cam workaround that trips people up.
Single centered host cam → Short (direct)
A solo episode with the host framed dead-center in 16:9. The center crop is exactly the right tool — no manual cropping.
Clip: ep42-host.mp4 1920×1080 52s (host centered) Crop: 607×1080 from x≈656, y=0 (center) Scale: 607×1080 → 1080×1920 (lanczos) Trim: -t 60 (52s, untouched) Out: 1080×1920 H.264 CRF20 / AAC 128k
Two-cam side-by-side (the common mistake)
Host left, guest right in a 16:9 two-shot. The center crop keeps the middle — mostly empty space. Crop each speaker first to make two clean Shorts.
Clip: ep43-twoshot.mp4 1920×1080 (host L, guest R)
Wrong: shorts-formatter → center 607px = the gap between them
Right: video-cropper → 607×1080 over the HOST (x≈100)
video-cropper → 607×1080 over the GUEST (x≈1200)
then shorts-formatter re-scales each to 1080×1920Highlight at 34:00 of a 90-minute episode
The good exchange is deep in the episode. Trim it to the front, then format — the dialogue track re-encodes cleanly to AAC.
Step 1 lossless-trimmer: 34:05–34:55 → take.mp4 (50s)
Step 2 shorts-formatter: take.mp4 → 1080×1920, -t 60
audio (e.g. 320k MP3 bed) → AAC 128k
Out: 50s Short, exchange front-loadedAdd captions for sound-off feeds
Most Shorts autoplay muted. Format first, then burn the transcript so the punchline reads silently.
Step 1 trim → punchline.mp4 (38s, centered guest)
Step 2 shorts-formatter → punchline-9x16.mp4 (1080×1920)
Step 3 subtitle-burner: punchline.srt → captioned Short
(style preset: youtube/tiktok/bold)Bleep a swear before publishing
Podcast clips sometimes need a span muted. Mute the region first, then format — the formatter has no audio editing of its own.
Step 1 trim → clip.mp4 (45s) Step 2 audio-mute-region: mute 12.0–12.8s (the word) Step 3 shorts-formatter → 1080×1920 (audio already muted span) Out: clean, advertiser-safe Short
Edge cases and what actually happens
Two-shot where both speakers are at the edges
Cropped outA side-by-side two-cam loses both speakers to the center crop, keeping the gap. Crop each speaker individually with video-cropper (making two Shorts), or use auto-reframe for active-speaker-style tracking.
Guest framed in the side third of the shot
Cropped outEven a single guest framed off-center is clipped by the fixed center crop. Pick the right column with video-cropper before formatting.
Highlight is deep in a long episode
By designThe formatter keeps only the first 60 seconds, so a 34-minute mark won't appear. Trim it to the front with lossless-trimmer first.
Podcast has on-screen episode branding at a corner
Cropped outA show logo or episode number in a side corner sits in the discarded width and disappears. Re-add branding to the Short with watermark-engine after formatting if you want it consistent.
Lossless audio bed (PCM/FLAC) in the clip
SupportedAudio is always re-encoded to AAC 128 kbps. A high-bitrate or lossless podcast track becomes 128 kbps AAC — transparent for speech and typical music beds, and exactly what YouTube would do on upload anyway.
Profanity or copyrighted music in the exchange
Risk (off-tool)The formatter doesn't bleep audio or detect music. Mute a span with audio-mute-region before formatting; the formatter itself only re-encodes whatever audio is present.
Vertically-framed phone podcast recording
SupportedIf your podcast was already shot 9:16 (e.g. a phone-recorded interview), there's no crop to do — the formatter just re-scales to the canonical 1080×1920 and re-encodes to spec.
Multi-cam grid (2×2 quad)
Cropped outA center crop of a quad grid lands on the seam between cams. Crop a single cam tile first with video-cropper, then format that tile.
Episode clip exceeds your tier file-size limit
RejectedThe cap applies to the clip you format (Free 1 GB, Pro 10 GB, Pro-media/Developer 100 GB). High-bitrate multi-cam ProRes masters can be large — trim a shorter range or transcode first to fit.
You want both speakers visible in one Short
Wrong toolThis formatter crops to one 9:16 window — it can't stack or split-screen two cams. Keeping both speakers means a manual edit; the formatter is for a single centered subject per Short.
Frequently asked questions
Does it work for a two-camera podcast setup?
Only if a single speaker is centered in the cut you give it. For a side-by-side two-shot, the center crop keeps the empty middle — crop each speaker separately with video-cropper first to make clean per-speaker Shorts.
How do I get my best exchange instead of the episode intro?
The formatter keeps the first 60 seconds, so trim the exchange to the front with lossless-trimmer (instant, lossless) before formatting.
Will my dialogue audio sound worse?
Audio is re-encoded to AAC 128 kbps. For speech that's transparent — you won't hear a difference. A lossless or 320 kbps source is recompressed, but YouTube would re-encode to a similar bitrate on upload anyway.
Can I add captions for muted autoplay?
Yes — but as a second step. Format to 1080×1920 first, then burn an SRT/VTT onto the vertical output with subtitle-burner, which has style presets (youtube, tiktok, bold) sized for Shorts.
How do I bleep a swear in a podcast clip?
The formatter has no audio editing. Mute the span first with audio-mute-region (set start/end seconds), then run the muted clip through the formatter.
Is the crop centered on the active speaker?
No — it's a fixed crop on the center of the frame, with no speaker detection. If your cam already cuts to whoever's talking and frames them centered, that works. Otherwise use auto-reframe for tracking.
What output do I get?
A 1080×1920 (9:16) MP4, H.264 CRF 20 + AAC 128 kbps, capped at 60 seconds, with +faststart. Source frame rate is preserved.
Can I keep both host and guest in one vertical frame?
Not with this tool — it crops to a single 9:16 window. A split-screen or stacked two-speaker layout needs a manual edit. Most podcast Shorts feature one speaker per clip anyway.
Is my unreleased episode safe to process?
Yes. Everything runs in-browser on FFmpeg.wasm — the episode never uploads. Safe for embargoed releases and guest footage under NDA.
What input formats does it take?
MP4, MOV, MKV, WebM, AVI, M4V, and TS. ProRes inside a MOV decodes fine; output is always MP4 (H.264/AAC).
My clip is 90 seconds — will it just cut the last 30?
Yes — -t 60 keeps the first 60 seconds and drops the rest. Trim to ≤60s first so the cut lands where you want, not arbitrarily at the one-minute mark.
Can I batch a whole episode's worth of clips?
Format one clip per run. Cut all your highlights with the lossless trimmer (fast), then format each — the formatter processes single files, so it's a quick loop.
