Video Stabilisation & Deflicker

In most cases yes. Rather than zooming in to hide the revealed edges, the missing areas are filled from surrounding frames where that information exists, so the delivered frame stays at source resolution. Where the shake is extreme there is a genuine trade-off between how much correction is applied and how much edge has to be reconstructed, and that will be explained before the work starts.

Gate weave is the small side-to-side and vertical drift introduced when film moves through a camera or a scanner. It is subtle on a single frame and very visible in playback, particularly against a locked-off background or a title. It is removed by tracking the frame itself rather than the content and correcting the drift, which is a different process from stabilising handheld camera shake.

Yes. Exposure flicker from shutter and lighting mismatches, and the pulsing that appears under certain artificial lights, are evened out across the sequence. Deflicker is usually combined with stabilisation because both are prep problems that make every downstream task harder if left in.

Because unstable plates make everything downstream harder and less accurate. Tracks slip, patches drift, and mattes that hold on one frame break on the next. Stabilising as part of the prep pass means the compositing work is built on a steady plate, and the original motion can be reapplied at the end if the shot needs it.
