editing in AVCHD not running smooth, jittery,whats up
Ive worked with vegas for 6 years now, no probelms running avi files, when I go to work on MTS files (AVCHD) the playback is jumpy slow, and thats with no fx, my computor is pretty good, 3 giga hrz dual processor, 4 gigs ddr ram ,a gamers video card 1 gig, 1333 front bus windows xp 32 bit,service pack 3, my question is do I need a quad core, upgrade to windows 64 bit more ram, buy a mac, or purchase software like cineform, upshift, which at the moment I dont know anything about, I have tried all project settings cause none work smooth, again never had problems before AVCHD, even renderd them down to avi’s it takes 2 minutes and 20 seconds to render 1 minute of AVCHD (.MTS) to an avi, and worse yet it doesnt look the same, MTS native looks sharp, very in focus, the avi slightly blur’ie, would like to know what is recomended with this format, what do you have to do or get to run avchd smooth, ANYONE ? THANKS

AVCHD is very demanding on processors. It plays back smoothly on my Quad Core with Vegas Pro 9.0 so to answer your question directly, yes, getting a Quad Core and the latest Vegas software will allow you to playback AVCHD smoothly.
If that’s not an option, I would definitely try a solution that converts AVCHD to something easier to edit. AVCHD UpShift will convert AVCHD to HDV (.m2t) files which are easier to edit. CineForm Neo Scene will convert AVCHD to CineForm HD (.avi) files. Both have a free trial download so I would recommend that you download both and try them and see which plays back smoother on your PC.
Finally, VASST GearShift allows you to create DV Widescreen (or any) proxies and edit at DV resolution quickly and then swap back to the full AVCHD source before rendering. This differs from CineForm and UpShift because in those solutions you don’t need your AVCHD files anymore and render directly from those formats. With GearShift you edit with SD resolution proxies and then swap to HD AVCHD files for full quality rendering.
Those are 3 options for you.

JOHN, thank you for responding, I know software, dont know how to build computors, dont have alot of money, also dont want to waist what I do have, what type of system would you recomend me getting to be able to edit in AVCHD, how fast ? how much ram ? THANK YOU

Just get a Q9650 CoreDuo Quad and Cineform NeoScene. Maybe $450.00. Also get more RAM. It is cheaper than a new machine.
I hope that helps.

sounds good what operating system, with my pc, also I got to figure out what this Cineform NeoScene is, I’ve heared you talk about it in other posts, does it convert your files so you can edit faster and smoother, is there a way to use and edit my native MTS files, again my system works with them now it just doesnt run smooth
THANK YOU

Yes, exactly. Converts .mts to high quality .avi with best colorspace in the industry.
I leave my preview window on Draft or Preview, and it is still a little choppy, but not bad. I can imagine that with only two cores it would be impossible. With four fast cores it is not bad, but you still have to leave it on Preview or Draft.

I see that Normal already answered about the CPU. I have 8GB of RAM in my Vista 64 system and it seems to be enough. XP32 can only see 3.25GB so anything more that 3GB on XP is a waste.

I rebuilt a Core Duo machine with a view to smooth preview in Vegas 9,- i7 920, 16Gb RAM, RAID 0, 2x 8600 cards.. nothing doing: you still get some stuttering particularly where transitions etc. are used.
The extra power has, however, made a big difference to rendering times.
The best hope seems to be for Sony to make use of the GPU or for GPU Decoder to become usable. GearShift is a good idea though I’ve found it produced an irritating banding or moiré effect in preview.. unless there’s something I’m getting wrong.

I was in the same boat as you not that long ago. I ended up getting a much stronger computer, but still had issues with playback. John had recommended Cineform, and after some tweaking, it works great for me. I would strongly recommend it for editing AVCHD.
Good luck
