Infoseite // Video is grainy



Frage von Sven:


Hello,

I want to trim, family videos of Mini-DV (SonyHC32E) / join (no special effects) and then burn to VCD. In principle, the synonymous everything works, but: The video material is then very grainy.

I switched to the FAQ-tips already on capturing via Firewire, the Calculator (AMD Sempron, 512MB RAM, XP should be synonymous fast enough Pro).
I have tried to capture with the included Sony software, with Ulead VideoStudio 5 (of the firewire card) and Windows Movie Maker. Klappt synonymous actually quite good, each source format DV-PAL, but the resulting AVI is great, but looks quite good from s.Screen. Also the cut goes well, the functions of Movie Maker to give me perfect.
When compressing it seems to occur but a strong loss of quality, the result is unpleasant grainy (about the same in all programs).

Frage1: I have never updated any codecs, so in this area only the standard XP codecs. Could this be the reason or what codecs to encode in a (S) VCD sense would make / where can I find? Googling brings me to a confusing variety ...

Question 2: When you encode AVI to Mpeg with Ulead VideoStudio 5 provides you run along s.Screen the video. This jerky, the picture appears in front and back. Here takes place the conversion Interlace / non-interlaced, which causes the loss of quality? I have never found a setting to do so. As the camera keeps track of how it is when a (S) VCD?

Question 3: So far I have only a CD burner, the corresponding synonymous Nero burning (only normal VCD MPEG1 would therefore be). How many minutes of video when I get around to a CD? Would the above to solve quality problems in the switch to a DVD Burners, MPEG4 is so much better compared to MPEG1?

For the compilation of individual MPEG sequences and create a menu was still at the Camera Pixela ImageMixer here that offers me enough functionality.

Thanks for your help, synonymous when the subject was probably many times on it, but neither the old nor the articles forums FAQs far I have found the solution.

Regards

Sven

So on a (S) VCD, you never get a really good quality. Namely, we can Resolutiongehen only up to a certain bit rate /. On a DVD (MPEG2 files, not MPEG4 - MPEG4 is something like DivX ...), however the quality is very good. The purchase of a DVD burner is recommended so much.

The camera is recording in Halbbildreihenfolgenschema on a TV, s.Computer only for the prestige of the video, you need a different setup. When you create the video do not therefore have to be deinterlaced.

Hello Sven, the DVD Mpeg2 codec is not Mpeg4. But the answer is yes, with a DVD when there is a reasonable data rate (about 7 Mbps) no visible loss of quality. In Mpeg1 picture-and audio information are added together, the image size is usually half of DV. It fits about 1 hour on a blank CD. Roughly the same Mpeg2 fit on a 5 DVD. The sound can be PCM or AC3, but it is certainly a separate file. Another good news is pretty fast Mpeg2 encoded in Comparison to Mpeg1.
