Frage von Andy Garcia:
Hello,
I intend a HD camcorder to buy. Now the question arises as to the storage media: hard disk or dvd dv
as far as I am aware, is the film for DVD and Hard Disk camcorder is compressed, resulting in a further editing with an editing program is difficult. it is true? because I liked the film next wants to edit, I only dv cassette, right?
For this reason I have for SonyHDR-HC7 * decided *
I can at SonyHDR-HC7 high resolution, uncompressed export (avi) to show them later in an editing program to edit next. or can I only in PAL resolution in uncompressed avi export? I ask because in your test under 'Compression format is DV and MPEG2.
wiki is to be in High Definition Video: The recording of the video compression is done in MPEG2 with a data rate of about 19 Mbps at around 720p and 1080i at 25 Mbps.
means that HDV mpeg2 komprmiert always is?
look after me when my formula is not so perfect.
thank you for your help
Antwort von Udo Schröer:
DV video is always compressed DV (mini DV tape)
HDV1 (720p) HDV 2 (1080i) is always compressed mpg. (Mini DV tape)
AVCHD (Own codec) similar HDV to DVD - HDD - Stick
Antwort von Andy Garcia:
hallo udo,
how can I then HDV movies cut / edit. I always thought mpg compression is difficult to cut. it is not so?
Antwort von Udo Schröer:
The tape of HDV Cam is just like a DV tape loaded. Your editing software should HDV editing support.
To my knowledge, it is primarily of DVD video cameras and HDD problems because there is no real HDV stream is more.
AVCHD is a new system to synonymous quality HDV to DVD and HDD to be included. Some programs aim to support, but even so had no experience.
With an HDV camera with mini DV tape, you're safe at the moment still on the right page!
Antwort von Quadruplex:
MPEG (precisely: the variants, the PAL-DVD and HDV are used) are always difficult to handle - simply because not every single totally separate and completely saved. (In the professional field, there is MPEG-variants, which - like DV - only within a reduced image data - is then: I-Frame only.)
For PAL, it has only disadvantages, MPEG-taking procedures - since DV is the medium of choice.
HD's are affordable only with data reduction, which works on multiple frames.
The point is: For HDV works in the meantime with affordable and reliable computers for AVCHD, there are many things still not synonymous with the requirements s.den PC again are higher.
So: If you are now actively want to edit your movie, take HDV. If you nix makes your shots in the (presumably) the next six months to one year only rudimentary edit pages, AVCHD is interesting.

Quadruplex and hallo udo,
thank you for your reply
MPEG (precisely: the variants, the PAL-DVD and HDV are used) are always difficult to handle - simply because not every single totally separate and completely saved. just as I understood it.
The point is: For HDV works in the meantime with affordable and reliable computers, [...] it is called, it works, but not as good as pal dv material?
If you now actively want to edit your movie, take HDV. If you nix makes your shots in the (presumably) the next six months to one year only rudimentary to be able to process what exactly do you mean?
another would have to ask myself: if the hd material anyway in mpg (mpg which version of Virden hd material used?) is compressed, it is not better the disk variant, instead of cassette, to take the head / the mechanik to spare ?
another way: where is the difference between cassette and disk mpg? there is one?
Antwort von Jan:
No, because even harder compression used (MPEG HD HDD = 4) - this is one for the PC & editing program even more difficult, the motion representation with HDV is synonymous better.

Antwort von Quadruplex:
it is called, it works, but not as good as pal dv material? The cut itself goes, powerful calculator, provided as good as with PAL-DV. You searched simply because of the MPEG compression has limitations in the original material (possibly jerky / fuzzy movements, block artifacts, etc.). The course is made in the post-impact.
what exactly do you mean? So hard to understand? If you put your videos now and today, with all edit chicaneries want to take HDV.
what mpg version of Virden hd material used? HDV: MPEG-2, AVCHD MPEG 4/H.264
is it not better to festplatte variant, instead of cassette, to take the head / the mechanik to spare? The question is (almost) no. HDV, there are currently only with tape. JVCs GZ-HD 7 adopts MPEG-2 to hard drive on and can send it as HDV firewire output. Internally, however, he uses MPEG-2 transport stream (TS), means that the container file of JVC differs of the of HDV.
With AVCHD you currently have the choice between four media: hard drive, DVD, SD Card, Memory Stick. However, there's synonymous because different sections - the videos of the different manufacturer are not always compatible.
Antwort von AndreasBloechl:
I'd been alone because of the archiving HDV use only. The DV tapes can be more easily archived. I archive is still synonymous dv material to two ext. Hard disks in parallel but only on hard alone is not so sure I like yet zuätzlich to have the tapes.

So massive and Splinting visible at normal playing HDV material is even with HDV2 hard to find in HDV1 even less. And in doing Jerkiness 1080 50i definitely nothing, absolutely unsuitable for a maximum view or playback devices. Fuzzy movements will be in an interlaced HD procedures in the field due to the interlaced flicker can not avoid, see synonymous Kell factor and the consequent lowering of the resolution lines around pans.
Unlike HDV versus AVCHD we have here again the relevant points taken together:

Antwort von Quadruplex:
So huge and visible Splinting (..) That's why I wrote: "may" or the long version: may ...
Antwort von wolfgang:
Na and others: Have you ever had the material that you have the hardware encoder on the Jordan've driven? Say: massive Splinting've generated? I myself have not managed to trunk once reported. Could some of intensely moving water surface, or a rustling forest leaves occur - that is where we sowas synonymous from the good old times SVCD know. But I've seen to this day do not.
The sharp jump the other hand, one can regularly observe - such as before a swing, if the picture is a picture dormant, and if the swing starts and stops again.
So as you can have a little differentiation.
Antwort von mauriceg@gmx.de:
hallo freunde video,
if I hd material exported under the cut (not in PAL resolution) and burn to dvd. Run with what can I expect? or do I need dafuer blueray disk?
Antwort von mauriceg@gmx.de:
approximately 24 minutes for MPEG2 HD ..
about 45 minutes as AVCHD ...
