Confusion about the video format of the JVC Everio HD 30 / 40 - AVCHD / MPEG
Frage von funsinn: September 2008
The two new JVCs can 2 Video format: AVCHD and MPEG ... I can but as synonymous with the SonyHDR-SR11 me for one of these formats to decide ... Where is the difference between the cameras? Does this mean the JVS actually in 2 formats, while for example the Sony Then while Resolutionwie MPEG-2 - but not a FULL HD - offers? Synonymous words, if I "only" a Calculator Intel (R) Core (TM) 2 CPU email@example.comGHz for me so important that editing, I must at Sony Always (!) Of only convert AVCHD to MPEG? And .. how big is the loss of quality? Yes - ok - I am a beginner ;-)
Antwort von WoWu:
The JVC shall be in MPEG2 or MPEG4-AVC on. MPEG-4 AVC is the modern standard and is based on MPEG 2, is only about 10 years to develop next. In MPEG2 you'll be satisfied with 1440x1080 need. AVC has also considerably finer tools for image editing and specifically in the processing of motion. You now Codierst of AVC to MPEG2, your result is only as "good", such as MPEG2. Then maybe the same work on MPEG2. With regard to the processing, it is less s.Deinem Calculator and more s.einer customized software within the computer architecture. New operating systems are certainly the future this fact into account. ADOBE NLE uses in his solution to an appropriate graphics card back to the computing work in the GPU provides adjusted.
For the difference in quality just as much: In AVC, there are a number of available profiles and levels, the different results in terms of generating the image. Unlike MPEG2 so it is important that the tools from the manufacturer have been implemented. Often the picture is different in the current of MPEG2 camcorders were not as dramatic, because the manufacturer prefers the advantage of lower data rate in use. However, comparing the image quality at data rates identical with each other, there are significant improvements in quality. Conversely, this means synonymous but that you have the same quality images at lower data rates will get. The Blu-ray Association has a test result as that for a quality AVC 16 Mbit / s in MPEG2 24 Mbit / s would be required and that of the test persons (1,750) s.16 Mbps virtually no difference to the original material more could be detected. But: As I said, it always comes to the profiles of AVC. This test was done with the FRExt .... Using Profiles, or other vendor tools, you can once again look different.

The HD30/40 but have firewire. And HDV is mpeg2 HD via firewire. If you go to mpeg2 converter, because that means it is not that the two HDV camcorder then spend? If not, what distinguishes the Everios to the mpeg2 HDV? mfg Section Head

Hello, can both the JVC HDV Conformal files via firewire and record output but synonymous Full HD Mpeg2 record .. the files are transferred USB2 vie ...
Antwort von domain:
To definitively clarify a small addendum: both "HDV" (1440x1080) as synonymous Full HD (1920x1080) can be recorded in Mpeg2 and transferred via USB. Simulated additional HDV via firewire. Full-AVCHD (ie 1920x1080) can only be played via USB.

What is it again please?

Recorded on disk, but as m2t transport stream via firewire as of an HDV camcorder off. Relatively pointless, incidentally, who will voluntarily do, except his NLE can not Full HD Mpeg2 cutting
