Custom crop and aspect ratio in Pavtube for social media

Social platforms rarely display every frame of a video in the same way. A tall clip made for a Reel can lose faces, captions or logos when uploaded to a square feed, while landscape footage can be cropped too tightly when forced into a vertical story. Sydney and Melbourne creators often prepare several versions from one shoot, especially when the same event needs to work across Instagram, TikTok, YouTube and Facebook.

Pavtube provides a practical way to make those versions without repeatedly editing the original. The important distinction is between cropping the visible image, changing the output canvas and stretching the picture. Once those are understood, a custom crop and aspect ratio can be set once, checked on a phone and reused for a consistent campaign or a busy content calendar. Learn more about Resource.

Start with the destination frame

Every export should begin with the platform and placement, not the camera dimensions. Use 9:16 for Instagram Stories, Reels, TikTok and YouTube Shorts; 4:5 for a taller feed post; 1:1 for a square feed; and 16:9 for YouTube, Facebook or LinkedIn video. Platform interfaces, duration limits and overlay positions can change, so check the current publishing guidance before a major campaign. Learn more about How To Convert Various Iphone.

The usual working dimensions are 1080 × 1920 for 9:16, 1080 × 1350 for 4:5, 1080 × 1080 for 1:1 and 1920 × 1080 for 16:9. Their ratios are the width divided by the height, which is 0.5625, 0.8, 1 and 1.7778 respectively. Keep every dimension even and avoid a ratio that looks similar but rounds to a different display.

Before importing, confirm the source resolution, orientation and frame rate. iPhone footage may arrive as HEVC with HDR, colour metadata or rotation details that a desktop editor must interpret correctly; the [iPhone conversion guide] explains several of those cases. Working from a clean, unedited source copy also makes it easier to compare exports later.

Set the crop in Pavtube

Open Pavtube on Windows or Mac, import the clip and place it in an editing project. Select the item in the preview or timeline, then open the crop or resize controls. Menu names can differ between versions, so look for Crop, Resize or Canvas rather than the separate compression settings. Preview the selected clip before confirming any change to its dimensions.

Choose the custom option, enter the target ratio or width-and-height values, and keep the proportions locked. If Pavtube provides Ratio and Lock fields, choose 9:16 and lock the image; if it provides pixel fields, use 1080 and 1920. Drag the crop boundary to choose what remains visible, then reposition the source inside the frame. The result should fill the canvas without thin bars, bent faces or squeezed lettering.

A vertical crop from horizontal footage always removes part of the scene. Centre the crop on the speaker or action, but use the preview rather than the source monitor to check what viewers will see. If the full landscape composition matters, create a 9:16 canvas and fill the empty area with a brand colour or a deliberately prepared background, provided that option is available in your Pavtube version.

Check framing, motion and quality

Preview the full sequence at actual size, then scrub through the opening and closing frames. Keep faces, names and on-screen text away from the edges where platform buttons, captions or progress bars may cover them. A margin of roughly ten per cent on each side is a cautious starting point, although the safe area depends on the platform and the placement of the final post.

Cropping reduces the usable picture, while scaling enlarges what remains. A 1920 × 1080 landscape clip cropped to a full 9:16 frame contains only about 608 × 1080 pixels before enlargement, so filling 1080 × 1920 would visibly soften it. Record vertical footage, use a higher-resolution source or accept a designed background rather than relying on heavy upscaling.

Check motion at the crop boundary as well as the centre of the frame. A hand entering from the side may disappear after the crop, and a fixed title card may look balanced only in the first scene. Pavtube’s audio controls should be used separately to normalise speech, reduce peaks and confirm that music does not mask dialogue. If labels differ in your installed build, the [Pavtube support resources] provide a useful place to check the relevant workflow.

Match export settings to the platform

For broad compatibility, an MP4 container with H.264 video and AAC audio is a sensible social export. At 1080p, a bitrate around 8–12 Mbps usually balances detail and file size, but the source and platform matter more than an arbitrary number. Preserve the original frame rate when possible; Australian productions often use 25 fps, and changing it to 30 fps solely for social can introduce needless resampling or motion artefacts.

Make sure the output dimensions match the crop exactly and that no automatic letterbox or stretch has been added back. Review the finished file outside Pavtube, preferably on the phone used to publish. This catches problems that a desktop preview can hide, including tiny captions, oversharpened footage and a thumbnail crop that places the subject behind an interface element.

Australian connection speeds make this check worthwhile. An NBN upload can be much faster than a mobile connection, but congestion, Wi-Fi and local network conditions still vary. Test the upload before an event or sponsor deadline, keep a copy on the phone and avoid publishing large masters over a metered connection. For community campaigns, Facebook remains useful for Australian clubs and local groups, where members may watch on a mix of desktop and mobile devices.

Build a repeatable publishing workflow

Create a naming system that records the platform, ratio, duration and version date, such as a vertical reel, a square feed cut and a clean master without text. Keep the original source and an untouched project backup. Saving separate clean and captioned versions makes it easier for another editor, producer or client to identify the intended file without opening every export.

Pavtube’s conversion and compression tools are particularly useful for turning one approved master into several social files. Build the vertical version first when the footage contains a presenter, then create the 4:5 and square versions with the same framing logic. Recheck any movement between versions because a small change in crop can alter timing at the start or end.

Creators publishing cryptocurrency explainers can consult the [mining sector background] for factual context before writing claims into the edit. Once the footage is approved, export through the chosen platform, check the preview and keep the platform file separate from the archival master. This creates a predictable workflow in which every social cut has a defined canvas, a tested export and a clear place in the publishing schedule.
