Every draft in Selects has its own frame size and frame rate. The frame size sets the aspect ratio, and the frame rate sets how many frames per second (fps) the draft plays and exports at. A new draft takes both from the media you start it with, and you can change them whenever you like. This guide covers where the settings live, which sizes you can pick, and what carries through to your editing software.

The [Frame size] button is the small rectangle icon at the right end of the preview toolbar, just above the timeline. Hover over it to see its name and the current size. Click it to open the list of sizes and pick one. Your choice applies to the open draft straight away.

The control appears only while a draft or synced timeline tab is open. It is hidden while you are looking at a source file, because frame size belongs to a draft rather than to your footage.

To change a timeline's frame rate, or its frame size from outside the preview, open its Timeline settings. They live in the [Info] tab of the right-hand panel.

Each change saves straight away and is one step in your undo history. Frame rate offers the standard rates from 23.976 fps to 120 fps. When you change it, clips keep their timing in seconds.

The menu lists sizes rather than aspect ratios, so pick the dimensions that match the ratio you want.

[Original] sits at the top of the list and matches your source footage. Selects reads it from the first clip in the draft and shows the size next to the label, for example Original (3840 × 2160). If the first clip is not a video file, [Original] does not appear.

For any other size, click [Custom] below the list, enter the width and height in pixels in the two boxes, then click [Apply].

A 16:9 shot in a 9:16 draft stays a 16:9 shot. When you export a video from Selects, each shot is scaled down to fit the new frame and centered, with black filling the space above and below. If you need your shots properly reframed for vertical, do that in your editing software after the handoff.

A new draft or synced timeline that you make from media takes its frame rate and frame size from that media. If the videos have different frame rates, Selects uses the lowest one, and the frame size comes from the longest video.

If you drop media into an empty draft or synced timeline and its frame rate or frame size is different, Selects asks "Match sequence settings?". Click [Match source] to switch the timeline to the media's frame rate and frame size, or [Keep current settings] to keep both as they are. The first clip you place also sets the audio sample rate.

The frame size you choose carries through the handoff, so a 9:16 draft opens as a 9:16 sequence in Premiere, Final Cut Pro, or DaVinci Resolve. It also sets the shape of a video you export straight from Selects, while the [Resolution] you pick when exporting sets its size. A video you export from Selects also plays at the draft's own frame rate.

Open the draft, click [Frame size] in the preview toolbar, and pick 1080 × 1920. The draft becomes vertical and stays vertical through the handoff. Your shots are not reframed to suit the new shape, so plan to crop or reposition them in your editing software.

To change a draft's frame rate, right-click its tab and choose [Timeline settings], then pick a new rate from [Frame rate] in the [Info] tab. The change saves straight away, and a video you export from Selects uses the new rate.

You most likely set it on an empty draft, then clicked [Match source] when you dropped in your first media. Match source switches the draft to that media's frame size and frame rate. To keep your own settings, choose [Keep current settings] instead, or set the frame size again.

Not yet. Selects sets the frame your draft is delivered in, but it does not reframe the shots inside it. Automatic reframing and cropping are on the way.

[Frame size] only appears while a draft or synced timeline tab is open. If you are looking at a source file in the preview, switch back to a draft and it comes back.
