How to reframe a podcast video for shorts clipping
- Step 1Cut your highlight first — Auto-reframe reframes the whole input, so trim your viral moment out of the full episode first with the lossless trimmer (stream-copy, no quality loss) or the video splitter. You want a short, sharp clip before reframing.
- Step 2Open auto-reframe and drop the clip — Load the auto-reframe tool and add the highlight. Accepts
.mp4,.mov,.mkv,.webm,.avi,.m4v,.ts. The tool probes dimensions so the crop fits your real frame. - Step 3Set the Ratio to 9:16 — Shorts, Reels and TikTok are all 9:16 — the default. The dropdown also has
1:1and4:5if you're repurposing the same clip for the Instagram feed. - Step 4Check your framing matches a centre crop — A centred single host or a tight centred two-shot reframes cleanly. A wide two-up with guests at opposite edges does not — the centre crop lands between them. If your shot is wide, clip into single-speaker segments and crop each with the video cropper over the active speaker.
- Step 5Run the reframe — The tool applies
crop=<w>:<h>:(in_w-w)/2:(in_h-h)/2thenscale=<outW>:<outH>:flags=lanczos, capping width at 1080. A 1080p source gives 608×1080; a 4K source gives 1080×1920. Encode is libx264-preset medium -crf 20, AAC 128k. - Step 6Burn captions and publish — Shorts viewers watch sound-off, so burn captions onto the finished 9:16 clip with the subtitle burner — they survive the platform re-encode and sit inside the visible frame. For a hard 60s cap baked in, route through the youtube-shorts-formatter.
Podcast shot types and how the centre crop handles them
The crop is always centred. Whether that works depends on where your speakers sit in the 16:9 frame.
| Shot type | Centre crop result | Recommendation |
|---|---|---|
| Single host, centred to camera | Host stays perfectly framed | Use auto-reframe at 9:16 directly |
| Tight two-shot, both near centre | Both fit in the 9:16 strip | Use auto-reframe at 9:16 — check both stay in frame |
| Wide two-up, guests at edges | Crop lands in the gap; both half-cut | Split into single-speaker segments + video cropper |
| Solo / screen-share segment | Centred content kept | Auto-reframe at 9:16, or 4:5 for the feed |
| Three-plus panel, spread wide | Most panellists cropped out | Cut to active-speaker segments, crop each manually |
Clip workflow tools and where each fits
Auto-reframe is the reframe step. These siblings handle the trim, the off-centre crop, the captions and the length cap.
| Step | Tool | What it does for podcast clips |
|---|---|---|
| Cut the highlight | lossless-trimmer | Stream-copy trim at keyframe, no re-encode |
| Reframe to vertical | auto-reframe | Centre-crop 16:9 → 9:16 / 1:1 / 4:5 |
| Off-centre / two-up crop | video-cropper | Place a 9:16 box over the active speaker |
| Burn captions | subtitle-burner | Hardcode SRT/VTT so it survives re-encode |
| 9:16 + 60s cap in one pass | youtube-shorts-formatter | Aspect crop plus Shorts length limit |
Cookbook
Reframing recipes for real podcast shot types, with the crop you should expect and the fallback when centre-only isn't enough.
Centred solo host to a Short
A single host framed centre is the ideal case. The 9:16 centre strip keeps them sharp and drops the studio sides.
Source: 1920x1080 highlight, host centred Ratio: 9:16 Crop: 608x1080 centre strip Output: .mp4 H.264 CRF 20 / AAC 128k Then: burn captions -> publish to Shorts
Tight centred two-shot
When both guests sit close together near the middle of the frame, the 9:16 strip fits both. Verify the edges of each face stay inside the crop before committing.
Source: 1920x1080, two guests near centre Ratio: 9:16 -> 608x1080 centre strip Result: both heads inside the strip (tight shot) Check: if a shoulder/face clips, use video-cropper
Wide two-up — split and crop instead
The most common podcast layout (guests on opposite sides) defeats a centre crop. The fix is to clip per speaker and crop each to 9:16 over the talker.
Source: 1920x1080, host LEFT / guest RIGHT Ratio: 9:16 -> centre strip lands in the GAP Result: both half-cut, awkward framing Fix: 1. video-splitter -> cut into speaker turns 2. video-cropper -> 9:16 box over the active speaker 3. (optional) merge the cropped segments
4K studio recording to full 1080×1920
A 4K multicam podcast master gives a genuine 1080×1920 vertical, with the Lanczos downscale keeping faces and text crisp.
Source: 3840x2160 master highlight Ratio: 9:16 Centre strip: 1215x2160 Width cap: 1080 -> output 1080x1920 Result: sharp full-res Short
Reframe plus burned captions for sound-off
Most Shorts viewers watch muted. Reframe first, then burn captions onto the vertical so the words are always on screen.
1. trim highlight (lossless-trimmer) 2. auto-reframe 9:16 -> 608x1080 .mp4 3. subtitle-burner: hardcode clip.srt, tiktok style 4. upload to Shorts / Reels / TikTok Result: captioned vertical that reads sound-off
Edge cases and what actually happens
Wide two-up podcast guests both get cut
By designThe crop is centred and doesn't track the active speaker. With guests at opposite edges of a 16:9 frame, the 9:16 centre strip lands in the gap and cuts both. Split into single-speaker segments with the video splitter and crop each over the talker with the video cropper.
Auto-reframe reframes the whole clip, not the highlight
Trim firstThere's no trim control here — it reframes whatever you feed it. Cut your viral moment out of the full episode first with the lossless trimmer or video splitter, then reframe the short clip.
Free tier can't run it
Upgrade requiredAuto-reframe is Pro tier minimum; Free tier has video streaming disabled. Pro: 10 GB / 5 files. Pro+Media: 100 GB / 50. Developer: 100 GB / unlimited batch. No minutes cap — file size and batch count only, which suits long episode masters.
Names/lower-thirds at frame edges vanish
CroppedGuest name lower-thirds or logos near the left/right of the 16:9 frame fall outside the 9:16 centre strip. Reframe first, then add any captions or name tags onto the vertical with the subtitle burner so they land in the visible area.
Shorts 60-second cap not enforced here
Use the formatterAuto-reframe doesn't limit length. If a clip runs over the Shorts cap, trim it first, or route through the youtube-shorts-formatter, which combines the 9:16 crop with a duration limit in one pass.
Dimensions can't be probed
ErrorIf the FFmpeg probe can't read source size it throws Could not determine video dimensions. Multitrack-recorder containers can occasionally trip this — transcode first with the video transcoder, then reframe.
Output is 608 wide from a 1080p clip
ExpectedA 9:16 strip from 1080p height is 608 px wide, under the 1080 cap, so it isn't upscaled. Shorts displays it fine. For a true 1080×1920 master, edit and export your highlight from a 1440p or 4K source.
Audio re-encoded to AAC
By designAudio is re-encoded to AAC 128 kbps — there's no codec/bitrate choice. For voice-led podcast clips this is inaudible. If you need to clean up audio, do it before reframing as a separate step.
Frequently asked questions
Does it automatically follow whoever is speaking?
No. The crop is a fixed centre crop with no speaker detection or panning. It's ideal for a centred single host or a tight centred two-shot. For a wide two-up where each guest sits at an edge, split into single-speaker segments and crop each over the talker with the video cropper.
What's the best workflow for podcast clips?
Trim the highlight with the lossless trimmer, reframe to 9:16 here, then burn captions with the subtitle burner for sound-off viewing. For a hard Shorts length cap baked in, run the reframe through the youtube-shorts-formatter instead.
Can I reframe a two-camera podcast?
If your final cut is a centred single-camera shot at any moment, yes. If it's a wide side-by-side where both guests sit at the edges, the centre crop will cut them — split the conversation into speaker turns and crop each turn over the active speaker with the video cropper.
What size clip do I get for Shorts?
9:16 MP4 (H.264/AAC). From a 1080p source it's 608×1080; from a 4K source it's 1080×1920 because width caps at 1080. Both fill the Shorts canvas; the platform re-encodes on upload regardless.
Is my episode footage uploaded anywhere?
No. It all runs in your browser via FFmpeg.wasm, so raw episode footage stays local until your clips are public. Only an anonymous usage counter is recorded, never file content.
Which formats can I drop in?
MP4, MOV, MKV, WEBM, AVI, M4V and TS, plus generic video/*. Output is always MP4. A multitrack-recorder MKV, an OBS capture, or an exported edit all reframe the same way.
Will reframing hurt clip quality?
It re-encodes at CRF 20, near-lossless from a good source. Cropping plus re-encoding compounds existing compression, so reframe from your sharpest highlight export. A 4K master clip looks markedly crisper as a Short than a 720p one.
How do I add captions to a podcast Short?
Burn them after reframing with the subtitle burner. Most Shorts viewers watch muted, so on-screen captions are essential — and adding them to the finished 9:16 clip guarantees they sit inside the visible frame and survive the platform's re-encode.
Can I enforce the 60-second Shorts limit here?
No — auto-reframe doesn't trim. Trim first, or use the youtube-shorts-formatter, which applies the 9:16 crop and a duration cap together in one pass.
Is there a length or file-size limit on my episode?
No duration cap. Tiers limit by file size and batch count: Pro 10 GB / 5 files, Pro+Media 100 GB / 50, Developer 100 GB / unlimited. A full episode master fits comfortably on Pro or above; trim the highlight before reframing to keep encode time short.
Can I repurpose the same clip for the Instagram feed?
Yes — switch the Ratio to 4:5 for the tallest feed post or 1:1 for a grid tile, all centre crops. For Instagram-specific feed presets, the instagram-feed-formatter targets 1:1 and 4:5 directly.
Why is my centred two-shot still clipping a guest?
Even a 'tight' two-shot can push a guest's face or shoulder past the 9:16 strip if they lean out. Check the crop edges; if anyone clips, drop the clip into the video cropper and place a slightly wider or repositioned 9:16 box manually.
