Newsmeldung von slashCAM:Panasonic Lumix goes with 720p AVCHD lite of heidi - 28 Jan 2009 15:28:00 Presents with Panasonic Lumix DMC-TZ7 and DMC-FT1 two compact digital cameras, the high-definition video not only as a Motion JPEG (such as so far in this type of equipment common) but synonymous in a form of AVCHD can record. In the sub-Format "AVCHD Lite is the limited Resolutionauf 1280x720, the maximum bit rate is 17Mb / s. Incorporated is progressive, with the cameras is referred to as 60p frame rate is specified (synonymous in the German message, M-JPEG at 30fps) - quite unusual. As compared with Compression M-JPEG is considerably more effective, fit into more lite AVCHD video recordings to a SD-/SDHC card, however, the maximum continuous recording time of a clip 15 minutes (or 2 GB per recording).
Interestingly, we found the note on the new "AVCHD Lite" logo and the "AVCHD Lite" license: they apply to devices of the AVCHD video camera category, which is now synonymous with digital cameras counted. Especially for the detailed definition of

It is not thought to have made 720 to P as AVCHD Fossi?
Canon uses the digicams yes 1080er on the format, if it is not synonymous AVCHD is.
Sonyist lite synonymous with AVCHD s.Bord, well look in the future if it is not convenient times Videocams with AVCHD lite will ....

Jan, but you should now know what marketing is that one of their sayings and names can not give much.
Actually, it is but one way or the only buyer Vera ....

Sorry, double post.

Wolfgang (WoWu) I think because you have the correct perspective.
Where 17Mb / s at about 60p in the quality of 8.5 MB / s at 30p? It is twice the amount s.Bildern per second to be as compressed. When compressing in h264, I have noticed that the image not so much influence on the data has.
Is this so? Thank you.

I think 17Mb / s for such a small camera properly if you have a look recalled the JVC 720p at 50 frames with a data rate of 18MB / s and which has at an MPEG2 compression.
The documentary "princesses Bad" was exactly the same way with a camera and rotated to 35mm gefazt saw the relatively well off (compared to DVX100 or PD170).
At Panasonic, it is an H264 compression and 60 images / sec. can deliver very good picture, so the amount is an EX1. This provides the camera with 35MB / s with MPEG2 compression and 720p50 a very clear picture, why should then H264 (some 1.5 times effektifer than MPEG2) with 17Mb / s not just look good?
That little camera of course never s.eine EX1 HERRAN comes naturally is not an issue.
Antwort von WoWu:
@ Buildyo
Basically, the way to a few common data that can not be doubled with the Picture, is discussed in the image data addicts.
In AVC.H.264 you have always been very closely to the care which the producers like to hide, because AVC (HD) and AVC (HD) is far not the same.
The Manufacturer Profiles using for instance, and different levels. Sony power is still the "Main Profile", which is really the simplest can be described, which in HD is still bearable.
Pana and Canon are using the High Profile, which is already better tools in the color has. The next higher profiles would be more opportunities that currently do not use your camcorder.
You see, then, of the data (alone) is no longer really dependent on the quality of the image. This is (old) MPEG2 thinking.
You really must look exactly what the manufacturer s.Tools from the AVC-use offering.
Incidentally, even the high-profile tools that all the lower category better than the male Farbtools the EX1 in similar mode.
So no more of data rates are impressive, but only of that which implements the Manufacturer.
Antwort von GM:
The camera could be very interesting.
I took half a year before its predecessor, the Lumix TZ5 purchased (Video mode 1280x720, 30fps, MOV - PhotoJPG), as a photo s.sich clippers - I've filmed many years with the Canon XM2.
Unfortunately I must now admit that I more often feel that XM2 in the cupboard and leave with the TZ5 + Zoom H2 Field Recorder Outdent.
Because, although the TZ5 with only 3MB / s recording (with the inefficient PhotoJPG) is even in the picture is not particularly bright indoors better than the XM2 - The TZ5 comes in the video resolution is approximately at 450 LP / image width - slightly more than MiniDV (or in other words, such as MiniDV in 4:3, with the extra pixels without loss to come to 16:9). Super Sound Recorder provides the Field. Moreover, there is a wide-angle (28mm KB) without distortion - in a 220 ¬ machine!
Disadvantages are the limited manual controls (no control over shutter speed, ...) as well as the lack of depth here, and especially in dark situations, of course, has the XM2 nose (far) forward.
Furthermore, one can not in entities with a mini clippers can look - to look as professional XM2 already made.
My hope was that Panasonic times perhaps a firmware update to enable better data synonymous with more Resolutionrauszuholen - now I know why it does not exist.
The successor TZ7 with AVCHD in the Resolutionwesentlich could show more, because the margin in the Compression yes is bigger.
I'm very curious, a test would obviously Slashcam genial.

Antwort von buildyo:
Thanks for the replies.
Then I'm anxious to times the video quality. Still tense, I am on the HD, the Panasonic G1 with its swivel screen and hopefully fast AF during filming, and (hopefully) a camcorder manual controls should be even closer.
Antwort von Jan:
I was simply a matter that some thought Manufacturer, 1080i has won - and will s.sofort only supports P tot = 720
The Panasonic Sonyand P 720 now but as AVCHD (if synonymous lite) forward - is a bit odd. Why such double?
Canon relies on 1080 (SX 1), but that would not be a problem, Panasonic & Sony digicams synonymous spendier Resolutionzu a 1080er.
The TZ 7, yes synonymous first time a 2-core processor in it - you should probably have enough power with P to 1080 to come in - and yet you go to 720 P. ...
Well, perhaps Sony and Panasonic want your camcorder does not track too much at risk, with intent to bring "only" 720 P - since the two companies so good camcorder sales slide.
Canon is probably no preference, they do have with the 5 D MK II & SX 1 synonymous with the first Digicam 1080 P video.

The claim synonymous only to the train 720er overslept and now are very difficult to catch up ....
After all, the 720p50 HD TV system, which we look forward to.
(Besides, it is the better picture)
