is h.264 same as AVCHD?

[TsQ]

I tried googleing this but cant find the answer

I hv a AVHCD camcorder and i love the fact that i can have HD video files without the big storage space I need. Best !

so now i am looking for a PnS camera... and as you may know few models of Sony and Panasonic have AVCHD or AVCHD lite for their videos.

I researched further and see that Samsung and Canon states their camera movie files are format of H.264 compression

are there the same ?? I was told they cannot use the term AVHCD due to legal issue.. ?

pls help.. thks in adv

I think the best answer is from:
http://en.wikipedia.org/wiki/AVCHD
http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

Quoted from the above-mentioned links:
"AVCHD is a high-definition recording format designed by Sony and Panasonic that uses H.264 (conforming to H.264 while adding additional application-specific features and constraints)."

AVCHD files are h.264 but not all h.264 files are AVCHD.

Canon and samsung camera is using H264 now for their PnS and if its similar to AVCHD then i can widen my selection...

There's an interesting guide from B&H photo. Take a look.

http://hdslr.bhphoto.com/Guide.php?chapter=1#chapter=2

From one if the articles explaining different compressions:
H.264/AVCHD
"All Canon HDSLRs use the H.264 codec while the Pansonic offers an AVCHD option, which is a subset of H.264, applying a limited selection of the compression techniques specified in the full H.264 standard. Because of the H.264's predictive compression, fast-moving objects or panning across a frame quickly can produce artifacts in the image. Either technique is theoretically capable of better results for the bitrate than MJPEG."

ok guys... i cant say much about video quality as no one really do much compare and one shld not really dig too deep on video quality on a PNS camera (but if u can, than good to know & make decision)

What i did is to see the memory the video recording takes. The whole reason for me to get a AVCHD camera is mainly to save HDD space (MPEG is just a real killer).. I will be using this PnS as a camcorder too, as I just cannot bring so much with my kids already driving me nuts in holidays

For the benefit of all that has my idea of using a PNS , here is what i gathered:

m=minute , s=second ...

1GB= 14m 27s @720p (normal) 30fps

FINEPIX F300 EXR
1GB= 5m
2GB= 10m


MJPEG:
2GB=8min 20 sec
