computer power ghz ?

[luc13137]

i would like to know ,if anybody out there knows what kind of computer bomb you need to edit
and work easily with 1920 x 1080 60p,
i have a amd 3.01 ghz 2 core with 2 gb of ram and win xp.,i am using movie magix 16

with 1920 x 1080 60 p i can see i image that is not fluid with no sound

with 1920 x 1080 30 p i can see i little better image that is still not fluid with some sound that is
late and sound from outer space.

and for 1280 x 720 30 p everything is alright.

you have software and hardware problems

at this point in time only premiere pro cs5, edius 5.5 (or neo booster 2.5) can edit smoothly , assuming you have supported graphics card . You probably need quadcore or better as well

The resolution isn't so much the issue, it is the compression used. A weak CPU can easily edit uncompressed 1920x1080 but a RAID would be needed to store and play the ~1 to 3 Gb/s data stream.

By contrast, compressed video needs a fast CPU to decompress on the fly so one can play 1x or search/scan to an edit point. The amount of CPU power needed scales by total pixels (resolution) and the codec used.

Digital intermediate codecs (e.g. AIC or Cineform) are optimized for editing from a single hard disk (under 400 Mb/s). They contain full frames with light intraframe compression, so search/scan is possible with a moderate Core2 Duo CPU. The disadvantage of digital intermediate formats is their large file sizes (~60+ GB/hr).

MPeg2 is often used as an intermediate format from AVC source. MPeg2 is less compressed vs. AVC thus requires less CPU power (e.g. Core2 Duo). MPeg2 does use GOP based interframe compression, so file sizes are not as large as a full digital intermediate (~10-14 GB/hr) but at the cost of more sluggish perfromance.

Native AVC editing requires a very fast CPU (e.g. i5/i7 quad) to achive adequate performance. A new trend in high end editors is to access the GPU for hardware decode or filter assist to the CPU. This improves performance for native MPeg2 and AVC editing and also speeds filter rendering and export encoding.

It's primarily a software and GPU integration issue.

A 3- year old dual core CPU can handle 2-3 streams of 1080p24 AVCHD natively and smoothly with Edius or PPCS5. The exact same setup can't even handle 1 stream in Vegas 9 or PP CS4 smoothly. With CS5, a quad core with compatible card can do even more streams even rendering effects all in realtime, at full resolution quality

eddv thank you,but by the way,my camera works in mp4 avchd,
is it worst than mpeg 2,hope not!
but for the 2 other reply,maybe i should try one of your software,
i just dont like premiere since they change there way of adding effects,old premiere 6.5 or 7
that was ok for me,i just dont like working with markers.

It isn't a "better" issue. MPeg2 and AVCHD can have equal quality. The issue is camcorder AVCHD is heavily compressed to fit SD cards. It takes more CPU or CPU+GPU hardware capacity to search/scan an AVCHD file than it does for MPeg2 or a digital intermediate codec. The tradeoff is file size.

Premiere 6.5 or 7 (aka Premiere Pro 1.0) will be hopeless for editing AVCHD.

You would need to edit uncompressed with a large RAID.

i was just saying ,i don't like premiere cs3 cs4 cs5 because it doesn't work like 6.5 or7,
but now what do i do ,spent more rare money to update my computer,
or forget about 1080 and use 720 30p,that my computer handle well,
true there is not a lot difference to the human eye between both.
do you know if edius works with markers like cs5(i don't like them).
