Infoseite // Quality comparison between MiniDV - HDD and SD

Frage von s1n88:


Hello,
times I would like to know how much the difference of various recording media recognizes.

The best at the moment would be even MiniDV.
For HDD, the recording of MPEG2 compressed yes, which decreases the quality!

Hab reads, writes MiniDV with 25 MB / s and HDD with 9 MB / s.

But looks like now with the Flash memory (SD) from? This may indeed synonymous up to 22 MB / s or higher write, depending on how much money is for the SD-card from there.

Is there perhaps photo comparison between the 3 media? Sowas wäre echt klasse!

Mir gehts namely whether I now have a MiniDV Cam for use, or perhaps to an HD Cam with flash memory.

LG Nico

Quite so, it is not easy, because the data rates are of the formats, at best, only indirectly from the storage media. DV, for example, has 25 Mb / s, while the camcorder, the hard drive to record, mostly different data rates for election: poorer quality with long term or better quality with shorter duration. Exact details can be found in the technical data of these cameras.

Two key aspects in choosing an appropriate host format would USDI mechanical stress on your camcorder while recording (as points memory, because nothing moves) and the Nachbearbeitbarkeit recordings (as MiniDV scores due to lower compression).



Antwort von Jan:

For the ordinary citizen, there is no visible difference - the times have passed.

The best example is the Panasonic hard drive H 40 and the "identical" MiniDV GS 90 - the test values were very similar.

The new flash memory Camera Canon FS 100 Test image has almost the entire entry MiniDV squad beaten.

So you can see that now a MPEG 2 10 Mbit / sec film a HDD or Flash memory with a camera comparable MiniDV film are. Only professionals with very high standards and swing tests are a few differences.

4 25 Mbps MPEG movies would be the DV 25 Mbit / sec homemade highly superior because MPEG 4 with half-thirds and a similar data rate efficiency.

Our professional in the field is WoWu in its contributions so that you can intensively addressed.

And is not megabits megabytes! 25 MBit / sec is the data rate of DV, ca 1,5-17 Mbit / sec for flash and HDD units (but with the MPEG 2 & 4 Compression work).

The limited data rate the system on which it bassiert, you can not with tens of megabytes per second, because the device with the flood of data would be lost. Sowas with current technology is not possible.

It is synonymous for ordinary home videos is not needed.

The best example is JVC, the HD in the 5 & 6 attempted 1080 P (frames) through - impossible - they had in the processing of the data fields on runterechnen to cope with the data to come.

@ S1n88

Hi Nico.

What you would need would be a crash course through the video technology.
Jan has already begun, but you will have to have some patience, because the relationship between data rate, codec, Bitstream and the quality of a recorded image are really complex and reduces the data rate to almost last.
You should search your camcorder first and not focus on those parameters, but ask yourself what you want to do and what processing you want to make ... or if you have the material only on the TV (or PC) would like to view.
Markus in this direction has already made a step and Jan knows all the strengths and weaknesses of the camcorder. Since you're in good hands.
There are a few good synonymous additional pages in the network, and Bruno really think proboscis recommended and readable information, which you probably help next.
If it is then perhaps more technical details go, I'm happy synonymous but in the next moment you use bits and bytes little and give you as good as no evidence in the direction of camcorder search.



Antwort von s1n88:

hey, thanks for your reply and tips.

So if I understand correctly now, then is the difference between MiniDV and flash memory is no longer so great.
So I could go to a quiet synonymous HDCAM access, which only sd-card stores.

to me it's just important that I have no blocks in the building after that or so. or the image is blurred.

I'm doing videos that party in discos and it is very dark nunmal. and if then the mpeg2 compression is poor, then afterwards when I cut a bad image and I want to avoid. with MiniDV because it always looked good so far. but now is a separate cam ran, because otherwise I always have the cams from a rental received.

Had since a Panasonic NV-GS 500 with lamp?



Antwort von tommyb:

If a producer has a brand rausbringt the camera records only block, then it has developed a blind;)

Most cameras on the market to make good pictures in standard situations. Once the picture is too complex (trees with leaves, etc.), DV cameras fail just like HDV (AVCHD maybe not).

Please note only that you have to edit the material of which of SD Card camcorders will need a good calculator, because I know after all the good devices draw their clips in AVCHD on.

If the GS500 as faint as the GS400, then you need on each case, a lamp. Shooting in discos, however, is generally not so easy because of the lighting situation.

A "HDCAM" to buy would be in first class quality, but for the wallet sometimes a pretty bad slimming. ;-)

What I allude:
Buy HD Cam ... Yes or No?



Antwort von s1n88:

naja computer problem probably will not have none, have a very strong pc here ... but I'm still not sure which cam I now take ...

HDCAM's self slowly forward and MiniDV s.aussterben ... naja AVCHD and yes, I can always come down s.ende expected to DV, because many people who upload the videos afterwards, eh not able to watch HD video, because its probably the computer resolution garnicht create. So I could synonymous eig ne DV Cam take.

And yes AVCHD absorbs much more pixels and therefore the quality will be better if I had calculated down afterward, right? because DV takes only 720x576 at ... hd 1920 x 1080, on the other hand ...

or do I just wrong?

Data of your PC?



Antwort von s1n88:

AMD Athlon64 X2 6000 +
2 GB Ram
GeForce8800 GT
640 GB HDD

should be rich, had no problems with it at the Video Editing

Hey, it was my note above
