Frage von BenjaminFuchs:
Hello,
I have times a slightly different question. For the output of 640x360 pixel wide videos on the Internet I am looking for a suitable camera.
Now to my question is the quality (not the resolution) in comparison to the DVX to HVX better or worse? In how far is the codec used the HVX worse than the DVX codec?
Or playing for the 640x360 quality difference does not matter?

Now to my question is the quality (not the resolution) in comparison to the DVX to HVX better or worse? The DVX is in DV format (4:2:0) record, so like any other DV camcorder synonymous. - The HVX can additionally DVCPro50 and DVCProHD (both 4:2:2) record, making the Resolutionder Color is better.
Reinhartshausen of her recording format, the image quality of the HVX synonymous with standard resolution better. The extent to which the practice or what other factors play a role, would you like someone to answer, with the two camcorders have worked.
In how far is the codec used the HVX worse than the DVX codec? Not at all. The HVX is generated for a picture with 4-fold Resolutionauch the 4-fold amount of data. In addition, DVCPro50 and DVCProHD as opposed to professional DV recording formats.
Or playing for the 640x360 quality difference does not matter? The question you like, I can not so easily answered, because compressed video is another step comes into play, a significant influence on the achievable final quality: the type of compression (procedure and data).

If there are only Internet videos of such resolution, then I would certainly not take HD Camera.
What I am using 1080i or 720p aufzuzeichen then into a 360p to create?
But then I prefer a camera makes the PAL (720x576) Bastel all together and export the video in the desired resolution. And if it is interlaced, deinterlace then I think it even more.
Since the target resolution is PAL, it would be the difference between an HD Camera and an SD camera can not see. And as the picture anyway by Compression is raped (including 4:2:0 color space and possibly blurry artifacts and details) is the only advantage of a HVX only tapeless recording.
