FFV1.3 contains improvements and new features such as support for multi-threaded encoding/decoding, error resilience and integrity validation by CRC checksums, storing of display aspect ratio (DAR) and field order.

Within the video archiving domain, the interest in FFV1 is increasing, as can be seen in a thread on the AMIA-L mailing list, the PrestoCentre Forum or the
Archivematica mailing list. Companies are also picking up FFV1 support. For example, NOA (formerly "NOA Audio Solutions"), announced support for

FFV1 is not strictly an intra-frame format; despite not using inter-frame prediction, it allows the context model to adapt over multiple frames. This can be useful for compression due to the very large size of the context table, but can be disabled to force the encoder to generate a strictly

Early experimental versions of FFV1 used the CABAC Arithmetic coder from H.264, but due to the uncertain patent/royalty situation, as well as its slightly worse performance, CABAC was replaced by range coding.
