Talk:AVCHD

From Wikipedia, the free encyclopedia

Maybe something should be mentioned about how this compares to M-JPEG which is a non-temporal compression.

[edit] Resolution

Is there an implied resolution with the AVCHD format? For example we know that in HDV it is going to be either 1440x1080 or 1280x720. Is there a predefined resolution and aspect ratio for AVCHD? Also what about pixel aspect ratio - are they square of rectangular? Peel 22:09, 28 June 2007 (UTC)

Also, whether this format support 1080p or just 1080i? Does the camerca currently support only the interlace format? What about the use of the format in professional area? or this just for home user? --WikiCantona 07:57, 1 September 2007 (UTC)

True progressive formats are supported. AFAIK, Panasonic SD9 can record true 24p unlike Canon camcorders, which record telecined 24p-in-60i video. —Preceding unsigned comment added by Mikus (talk • contribs) 01:20, 22 May 2008 (UTC)

[edit] Recording AVCHD on standard DVD vs. Dual Layer DVD

Can someone with some knowledge on the subject tell me if you can record AVCHD format on a standard DVD-R or Mini DVD-R? I recently bought a new HD DVD Video Camera and I was told by the sales clerk that in order to "record/playback" in the full 1080i HD quality that the camera offers that I need to use a Dual Layer Mini DVD as opposed to a standard mini DVD (1.4Mp)

I understand there will be a difference in the amount of "time" I can record on a standard DVD vs. DL DVD... I'm not concerned about that... I'm strictly concerned about getting HD quality out of a standard DVD... Does it have to be Dual Layer??

No, it does not have to be Dual Layer. The clerk did not know what he was talking about. Mikus (talk) —Preceding comment was added at 01:19, 22 May 2008 (UTC)

[edit] Article Name

The article has recently been renamed Advanced Video Codec High Definition. It is correct, but it is more commonly addressed as AVCHD. The HDV article is not called High Definition Video. Or is that because there is already an article called High Definition Video? —Preceding unsigned comment added by Wuffyz (talk • contribs) 13:15, 1 October 2007 (UTC)

Moved to AVCHD. Mikus (talk) —Preceding comment was added at 01:17, 22 May 2008 (UTC)

[edit] Linux compatibility

As of yet, there are no all-in-one programs to edit AVCHD video. However, there are scripts that utilize multiple programs to convert AVCHD video to video formats that can be edited with Linux programs. The question is, can one of these conversion scripts be listed as a program under "Software that converts the AVCHD format to other formats"? Case in point: m2tstoavi

[edit] Don't mix file format and support

"Among the touted advantages of AVCHD over MiniDV tapes is random access," copied from the article is plain stupid. AVCHD is a file format and could as well be copied to mini DV tape.

Compare AVCHD and mpg2 video on dvd if you want... —Preceding unsigned comment added by 82.228.87.93 (talk) 14:45, 5 May 2008 (UTC)

[edit] Clarification on the Overview section

from the article "AVCHD supports a variety of resolutions and aspect ratios, all the way from 480/60i to 1080/60i "Full HD" with 1920x1080 pixels in 16:9 aspect ratio"

Full HD everywhere I've looked is called 1080p, 1080i is only the 'maximum' resolution of broadcast television, the specification for HDTV is very clear that 1080i is not the full capability of high definition TV(as a matter of fact 2160p is going to roll out in 2015, so now even 1080p isn't reall 'full hd' anymore, on paper at least). so if 1080/60i is the maximum resolution of AVCHD it shouldn't use the phrase 'Full HD' as it is not 1080/60p that is the standard resolution 'associated' with the phrase "Full HD" today.

frankly i think the words 'full hd' should be taken out, it's not the maximum resolution of HD content available today, and it's not even close to the maximum resolution in 2015 if anyone bothers supporting 2160p. Kesuki (talk) 20:58, 2 June 2008 (UTC)

Full HD is not a technical term, so I removed it along with other bla-bla. See spec table at the end of the article for supported resolutions and rates. Mikus (talk)
