Founder, klypra – @henri_tmpWe walk through the whole pipeline from Twitch moment to posted Short, with the actual export specs and the one step that decides how often you can post.
One Twitch moment, one 9:16 export, three platforms.
One clip, exported once at 1080 by 1920 as an MP4, posted to all three platforms. That single file is valid on TikTok, Instagram Reels and YouTube Shorts, so rendering platform-specific versions is wasted work.
The six steps between a Twitch moment and that file are always the same: find it, cut it, reframe it to vertical, caption it, trim the dead air, export. Done by hand that is 15 to 30 minutes per clip. That number, not any individual editing choice, is what decides how often you can post, and posting frequency is what decides whether the account grows.
The slowest step if you do it by scrubbing a VOD, and the one worth attacking first. Three shortcuts exist. Twitch's own clip button, if you were watching live. The VOD's highlight markers, which are unreliable but free. Or a tool that watches chat activity and marks the spikes for you, which is what makes the step take seconds instead of an hour.
Chat is a good proxy here because it reacts at the moment worth opening on rather than at the setup, and it does so within a second or two.
Start the clip at the reaction, not at the story that led to it. Viewers decide whether to keep watching in the first couple of seconds, and all three platforms weight that decision heavily. Aim for 15 to 45 seconds. Longer is allowed everywhere now, but watch-through rate is what gets rewarded, and a longer clip has more room to lose people. We go deeper on this in what actually makes a Twitch clip go viral.
A Twitch stream is 16:9 and a Short is 9:16, so something has to go. Do not letterbox: black bars top and bottom waste more than half the screen and read as lazy. Crop instead, and crop deliberately. On a gaming stream the facecam and the action are usually in different corners, so a naive centre crop throws away both.
The two layouts that work are a full-bleed crop that tracks whatever matters, or a split with the facecam stacked above the gameplay. Automated reframing that follows the subject saves this being a per-clip decision.
A large share of short-form viewing happens with the sound off. Burn the captions into the video rather than relying on platform-generated ones, for two reasons: auto-captions do not survive a download and repost, and they leave you no control over styling. Word-level captions, where words appear as they are spoken, hold attention better than a static block.
The moment chat reacted to is rarely centred perfectly in the window you cut, so there is usually silence at one end. Cutting it tightens the pacing and buys back seconds at the start, which is where they are worth the most.
Export at 1080 by 1920, MP4, H.264 video and AAC audio, 30 or 60 fps. Then post that same file to all three. The audiences overlap less than people assume, so a clip that does nothing on one regularly takes off on another, and the marginal cost of the second and third post is a couple of minutes.
The good news is that the three platforms have converged. One export satisfies all of them. Where they still differ is in length limits and in where their interface covers your frame.
| TikTok | Instagram Reels | YouTube Shorts | |
|---|---|---|---|
| Aspect ratio | 9:16 | 9:16 | 9:16 |
| Resolution | 1080 x 1920 | 1080 x 1920 | 1080 x 1920 |
| Served at | 1080p, 4K uploads get compressed | 1080p | 1080p, even from a 4K source |
| Maximum length | 60 minutes uploaded, 10 minutes recorded in-app | 20 minutes, but over 3 minutes is not pushed to new audiences | 3 minutes, raised from 60 seconds in October 2024 |
| Length that performs | 15 to 30 seconds | 15 to 45 seconds | 15 to 45 seconds |
| File format | MP4 or MOV, H.264 and AAC | MP4 or MOV | MP4, H.264 |
| File size cap | About 288 MB on iOS, lower on Android | 4 GB | 256 GB, irrelevant in practice |
| Interface covers | Username top, action buttons down the right, caption across the bottom | Roughly the top 220 px and bottom 450 px, plus a 4:5 crop in feed | Title and channel bottom left, action buttons right |
A 4K export is the most common waste of time here. All three serve at 1080p, so uploading 4K means the platform recompresses your file with its own settings instead of you controlling the quality at export.
Every platform lays its own interface over your video, and none of them warn you at upload. Captions placed near the bottom edge sit perfectly in your editor and end up behind TikTok's caption block or Instagram's progress bar in the feed.
The rule that survives all three: keep captions and anything else that has to be read inside the middle of the frame, clear of the top 15 percent and the bottom quarter. On Instagram there is a second trap, because Reels get cropped to 4:5 when they appear in the main feed, which trims the top and bottom of your 9:16 frame entirely. Anything important near an edge disappears there.
If you are posting one file everywhere, design for the strictest case rather than for the platform you happen to be looking at.
Every step above can be done manually, and for a handful of clips a week that is completely reasonable. The maths changes at volume.
At 15 to 30 minutes per clip, four clips a day is a two-hour daily job on top of watching the streams. People sustain that for a week or two, start skipping days, and the account stalls. Almost nobody quits clipping because they ran out of good moments; they quit because of step 1 through step 6 repeated forty times a week.
That is the argument for automating the pipeline rather than for automating any single step. A tool that finds the moment but leaves you to reframe and caption has removed the interesting part and left the tedious part.
klypra runs the whole chain while the stream is live. It reads the channel's chat, cuts at the spike, reframes to 9:16, burns in captions, trims the silence, and sends the finished MP4 to your phone over Telegram. There is no VOD to download and no export step, because the file is already the thing you post.
The free plan is €0 with no card, 5 clips a day and 50 a month at 1080p, with a watermark. The 5-minute setup guide walks through connecting a channel, and the tool comparison covers how the alternatives handle the same six steps.
1080 by 1920 pixels, 9:16, MP4 with H.264 video and AAC audio. That one export is valid on TikTok, Instagram Reels and YouTube Shorts, so there is no reason to render three versions. Exporting above 1080p is wasted effort: all three platforms serve at 1080p regardless of what you upload.
Three minutes, raised from the old 60-second cap for vertical video uploaded after October 2024. That is the ceiling, not the target. Most Shorts that perform still land between 15 and 45 seconds, because watch-through rate matters more than runtime.
Yes, and you should. A single 1080x1920 MP4 works everywhere. The only thing to watch is the safe zone, since each platform overlays its interface in slightly different places, so text placed too close to an edge can be legible on one and covered on another.
Only if your tool works from finished recordings, which most do. Downloading a multi-hour VOD to feed it to a clipper is the slowest part of that workflow. A tool that reads the live stream skips the download and the upload entirely, because the clip is produced while the broadcast is still running.
Fifteen to thirty minutes per clip once you include finding the moment, cutting, reframing to vertical, captioning, trimming dead air and exporting. That is the number that decides how often you can realistically post, which is why it matters more than any individual editing decision.
Yes, if you are posting the same file to several platforms. Platform-generated captions do not travel with the file, so a clip downloaded and reposted loses them. Burned-in captions are part of the video and also let you control the style rather than accepting each platform default.
The technical part of this is genuinely easy, and it has got easier as the three platforms converged on the same format. Export one 1080 by 1920 MP4, keep your captions out of the edges, start at the reaction, and post the same file three times.
The hard part is doing that consistently for months. That is a throughput problem rather than a skill problem, which is why the question worth asking about any tool in this space is not how good its output looks once, but how many minutes it removes from the forty times a week you have to repeat this.
