60 fps footage on vegas 11 pro
hi all , been around for quite some time now but only registered now.
good work you guys do around here.my problem is that i own a fairly weak computer (specs below) but still my passion for editing is greater than the limitations so im always trying to push boundaries with it.
i edit video game footage , so in this case 60 fps footage is the best for some extreme slow motions , problem is the preview is laggy and stutters a lot.
if i go play the clip on the WMP its butter smooth but in vegas it stutters and lags so much its a real pain to edit and do sincs.i know that with my specs i will never have a smooth playback with 60 FPS footage but is there anyway to make it a tad better just so im able to edit it?
already changed the dinamic ram preview , the window preview is on auto and displays the worst resolution possible.and if someone could explain why the video plays smoothly on WMP and not on vegas i would very much like to know it , even if it doesn´t help at least i´ll be glad to understand it.
thanks and keep up the great work.

Because WMP is a dedicated media player, Vegas preview window
is not..And with an under powered PC, choppy playback is a must.
So in your situation, the dynamic ram preview is your best
bet for previewing the timeline in realtime as you edit along
step by step. You can set your preview window to Preview (Full).Steve Rhoden

full? really?
but wont that make it strugle even more?in fact i lowered my dinamic ram preview to 1024 gb instead of the 2048 i had cause i read that it was stopping vegas from using all that memory that was reserved to dinamic ram preview only.
is this correct ?i do a lot of ram previews during editing but what i really need is some smoothness of playback during the small parts im editing so i can see what im doing in real time.

You could use Vasst Gearshift for your HDV .m2t files, AVCHD .mts files or even .m2ts files, MXF files, or Red R3D files to a DV Widescreen proxy stream. This means that even if you own a slower computer, or if you want to edit on a laptop or other less than optimal system for editing HD, you can use proxy streams for most of your editing work.
My system specs: Intel i7 970, 12GB RAM, ASUS P6T, Vegas Pro 10e (x32/x64), Windows 7 x64 Ultimate, Vegas Production Assistant 1.0, VASST Ultimate S Pro 4.1, Neat Video Pro 2.6

hummm… got to look into that , i got to be honest, i presume but i really dont know what that proxy stream is.
is it something like the vasst aplication taking care of the file reading hard work while i can normaly edit it on vegas through the preview window? kindda like having an auxiliary engine to vegas itself?

Proxies like Gearshift makes are standard def videos that you can use to edit on a slower computer. You can also just comvert all the videos in your project to DV widescreen avi, edit, then change your project settings to a custom 1080 60p, replace the DV proxies with your original .mts or .mt2s files and render to a custom 1080 60p format. There are no 1080 60p project presets or render presets in Vegas as of yet, haven’t tried Vegas pro 11 yet. I just make my own custom presets when working with my TM700 .mts files. I recently bought a Sony Vaio i7 laptop for about $900 and can edit the native .mts 60p files fine. Watch this video and see the preview is great. It can play back these files set to best/full and the preview looks like 60p to me. Of course this youtube video isn’t 60p but you can get an idea of what kind of preview framerate you can get with a fast computer.

man… wish i had that smootheness when playing 60 p footage 😀
but i gotta deal with my oldie q6600 and that´s my reality , going to look into that proxy things as im totally unaware as how they work, thanks for all the info , you guys were most helpful thanks.

[nelson araujo] “and if someone could explain why the video plays smoothly on WMP and not on vegas i would very much like to know it , even if it doesn´t help at least i´ll be glad to understand it.”
Basically, you have a pretty kick-ass GPU (I have the same one) and a relative weak (by this week’s four-core standards) CPU. When you play a video in WMP, it may be able to tap into video-specific GPU acceleration. Particularly, if you’re running Windows 7, you have an AVC decoder from Microsoft that uses the DXVA 2.0 interface to do much of the decoding on the GPU. So on my system, for example, I can use something like 60% of my hex-core AMD1090T to decode a 1080/60p AVC stream in realtime. Or, using GPU acceleration, easily do four or five of these at the same time.
Vegas 11 add some GPU acceleration (if you enable it, of course), and with the latest AMD drivers, you’ll get to use that. Make sure you’re using this… download something like GPU Shark to check your GPU use, then make it’s being used during playback.
It doesn’t have a profound effect on a single video stream, however — they’re still mostly using the CPU for decode, the GPU more for compositing and effects. I have seem some instances were preview goes 3x+ faster with the GPU acceleration in play.
You can make some general improvements in editing speed. In your project preferences, make sure you’re editing in 8-bit pixels, and have the quality set to “Good” or lower. And of course, you can adjust the preview windows itself in terms of quality and size of the preview, to speed things up.
