Video- / Filmqualität sich schnell bewegender Objekte (Kfz., Züge usw.)

Video - / film quality fast moving objects (car, trains, etc.)



Frage von s-a-l-s-a:
August 2007

Good evening,

as a beginner in the matter of moving images (so far only experience with analog and digital photography), I have a question about the image quality rapidly moving objects (car, trains, etc.):

Many here in the forum and in other selected Web sample videos of moving objects (a view perpendicular to the direction cars passing by) strong image disturbances in the form of streaks, blocks, etc..

Is this a general problem in the consumer area (too low volumes of data?) Or when a PC's processing of the raw material (DV) in favor of small amounts of data among mpg, avi files and others just too compressed?

I would mainly in the field of transport / moving vehicles / freight filming.

About detailed explanations, I am very happy. Thank you very much!

This is exactly the reason for Verpixelungen. During the compression must be yes, the amount of data be reduced and this is s.einem certain point just through the reduction of image content or frame rates.

I film for about 15 years in the main railway and mass transit, so I can tell you that in this field shows all the weaknesses, the technology can have. You get the best results in this area only with the best technology out. Fast trains, high contrast and many details such as lines and ballast stones - it is cheaper with technology is not manageable.

@ Markus: Thank you for the quick reply.

@ Pianist: Which camcorder class do you think is appropriate / owns you?
A Canon XH A1 is available at the moment it does not, then more of a HV20, HC7?
Also many thanks to you!

Uh - the answer to that would make you just miserable ... :-)

It depends on your personal requirements and your wallet, I do not know me, if you have a private or a profession.

I had to grin when I read the query and was very curious about your reaction. Since you did but very cautiously expressed. ;-)

@ Salss.Du find out, with contributions by typing the search term "Editcam" aufspürst.

@ Pianist: Because I use for a large television work, I know perfectly the opportunities and quality (s) of professional cameras. As a non-Kameraman (women) is the only shooting once only a hobby. Nevertheless, I would like the digital SLR photography sensible results. Can this area requires a camcorder like the HV20 afford?

Unfortunately I know with all the small cameras is not enough. Perhaps here is an Eisenbahnfan, which may say something about that. Quite a lump sum, I would naturally say "no", but that will not help you because I am so synonymous with a SonyXDCAM HD "no" say.

You might want to have the target device times out, railway s.einer a few shots and then turning on an appropriate rate monitor. But do fast, the day after tomorrow will be strikes.

Here's a video in HDV (Canon HV10 + Velbon DV -7000) from the Porsche Carrera @ mountain races.

I now have a total of 3 hr material recorded at the mountain races and the pictures are really 1A. So I see no problem "fast-moving objects" to film in HDV. All just a matter of camera work (a good tripod for this).

If you have more material for the buying need, just say it.

PS. And what creates the HV10, HV20 establishes synonymous;)



Antwort von Freak-X:

@ scream (Karol)
Thank you for the material, I must first look at rest.
