What is AVC LongG?

In 2015, Panasonic has started shipping cameras with AVC Long GOP capabilities.
Inside Panasonic's multi-codec AVC Ultra solution, AVC LongG occupies the lower half in terms of quality and bitrate.
FullHD recording at 25 or 50 Mbps offered by Long GOP codec is ideal for field recording, in particular ENG (Electronic News-Gathering). The 12 Mbps ultra low bitrate allows live transmission in wireless environments.


Pana AJ-PX800, one of the first models to offer AVC LongG

After a slow start, we are starting to see more damaged MXF files containing AVC LongG footage.

Detection

Starting with Treasured 4.0, damaged files containing any AVC Ultra variant, including AVC LongG format are supported. Treasured will detect presence of AVC media inside the corrupted video and show a preview.


Repairability

Inside the corrupted MXF files, the AVC LongG frames are stored inside KLV packets.
Video data inside the packet is similar to a raw H.264/AVC stream, and if data integrity has been preserved, media data can be extracted and re-wrapped into a new MXF container.

Therefore, AVC Long GOP can usually be repaired, restoring the original quality of video and audio.
