x264 --ref for AVCHD

[iSeries]

Hi,

Does AVCHD have the same --ref limits as Blu Ray? I.e 4 for 1080p and 6 for 720p.

Thanks!

I don't have a hard answer for you but I suspect that in this respect AVCHD and BluRay are identical.

The differences I could find are more at the file system / menus level? Check the AVCHD wikipedia page :

"AVCHD as distribution format

AVCHD has been designed to be compatible with Blu-ray Disc format,[2] and can be used for distribution of high definition video, albeit with reduced quality and interactivity compared to Blu-ray Disc.

Authored AVCHD discs use DVD media, simple menus, AVC encoding, and limit data rate to 18 Mbit/s. A conventional single-layer 12 cm DVD disc can store approximately half an hour of video recorded at this rate.

AVCHD content can also be mastered on SDHC cards and played by certain Panasonic and JVC television sets and Blu-ray Disc players. Data rate on memory cards is limited to 24 Mbit/s.

Blu-ray Disc media is not supported by AVCHD specification, though some software packages allow authoring AVCHD content on Blu-ray Discs. AVCHD encoding and container are compatible with Blu-ray Disc format, but naming convention is different. For better compatibility with Blu-ray Disc players, AVCHD video can be converted into Blu-ray Disc format without re-encoding audio/video streams. The resultant disc will play in any Blu-ray Disc player including those that do not explicitly support the AVCHD format."
