DSLR-Videos (550D) ruckeln, auch mit DNxHD

Videos DSLR (550D) jerk, synonymous with DNxHD



Frage von Backgroundworld:
September 2010

Moin!

I will get a 550D in the next few days - for that I've downloaded a trial of Videoaktiv Schonmal video.

But I get this in Sony Vegas Movie Studio Platinum 10 just not to cut. Nativ is a bit jerky.
If I disclose in DNxHD (10bit, 100% quality) transmuted, jerky it EXACTLY!

The CPU utilization when playing is always between 70-80%, synonymous with DNxHD.

PC: Quadcore of AMD, 4x3Ghz (Phenom II 940)


What can I do?
In-itself, it should with Avid DNxHD but less jerky?


Greetings
Nicolas



Antwort von Marco:

Movie Studio can with a 10-bit signal does not do much. Leave it in 8 bit, if possible.

What project settings you have chosen in Movie Studio?

Antwort von Backgroundworld:

Thank you!
Even with 8bit no improvement.

I have let the media take settings of the file (1080p25p)








Antwort von Marco:

What data rate has since the DNxHD-variant?

Antwort von Backgroundworld:

Thank you first for your answer!

DNxHD is 185MBit / s. (Bit much, but is recommended everywhere)



Antwort von Marco:

Then the bottle neck, which ultimately leads to jerking, may be the high data rate, which is thwarted by hard disks / bus systems. Since then the fastest CPU synonymous would do no more. DNxHD really need such high data rates?? Test it with the time half of it, if it is freely adjustable.
