What it is

VIP is an older VSM-era format used by Pfaff and Husqvarna Viking workflows. It still appears in legacy design libraries.

Satin Studio direction

Likely import support before export, after VP3 and compressed VSM-family research begins.

Versions and variants

VIP is not simply VP3 with another extension. It is reported to use compressed stitches, with compression behavior similar to HUS.

File identification notes

Treat VIP as a compressed stitch file until proven otherwise. Signature, palette, section boundaries, and decompression behavior are not yet verified in Satin Studio.

Observed structure notes

• VIP is still treated here as a compressed VSM-family lead. No complete public byte structure is established in this documentation.
• Expect header metadata, thread/color sections, and compressed stitch payloads rather than a raw expanded stream.

Structure sketch

VIP is reported as compressed VSM-family stitch data. Details must be verified per dialect.

struct VipCandidate<'a> {
    header_or_signature: &'a [u8],
    metadata: Option<&'a [u8]>,
    compressed_stitch_sections: &'a [VipSection<'a>],
}

struct VipSection<'a> {
    color_or_thread_metadata: Option<&'a [u8]>,
    compressed_payload: &'a [u8],
}

What we still need

Small and multi-color VIP files plus trusted-reader validation.
