Horrible Sony Vegas performance

[rocco123]

Im not able to enjoy editing videos because it's always buffering, loading frames or whatever, it gets stuck everytime, it's just a big mess, even if im under draft->quart or whatever the smallest resolution is, audio in preview quality too

My computer is a bit old but considering the resolution is like 240x200 or something... how in hell it can be that bad?

4GB RAM
MSI R7850
Q6600
4TB HD

Man what do I need to be able to do this properly? Im not doing that much, just cutting a bit, adding a couple plugins and sounds, and performance goes to hell, it's a struggle trying to edit a video.

It shouldn't be like that for 240x200 video on that computer. Unless your "couple plugins" are very computationally heavy, or perhaps you have other processes going on (e.g. virus scan running concurrently or maybe some games running in the background)

What does "it gets stuck" mean? Did you mean it's completely unresponsive, like a crash and irrecoverable? or is it just slow and you can still work, but just slowly ?

What are the source video(s) ? What format, what compression ?

Your cpu is 9 years old and your mb is ddr2 ram,to get better performance you will need to upgrade,cheapest thing to do is o/c the 6600 for a bit of a boost.Post a mediainfo the video in question.

Hi, stuck means, it gets in "not responding state" for like 15 or 30 seconds then it goes back, it doesnt totally crash, but it raises my cortisol, i think its making me lose hair just to be stuck every time as soon as I do something.

I actually dont need to drop any plugins for the experience to be stressing. Everytime I move the position of the | line thing to get in other frame, the frame needs to load. Everytiem I press play, it's a mess, the playback is not smooth. I have tried ram previews of shift+b, and they don't correctly work, they are so short, it's just so stressing.

My video is an .avi file at 1080p with "x264vfw - H.264/MPEG-4 AVC Codec" for compression (the actual source is an mpg file but it doesn't correctly work in Sony Vegas, I get glitches so I compress it with that first)

I know my computer is old, but im trying to get a preview at the 240p resolution, draft one, and this should be smooth...

[poisondeathray]

No, if the source file is 1080p with x264vfw, the seek performance will be very slow on your computer if you are using default settings. Reducing the preview resolution helps, but not as much as if the source was actually 240p because vegas still has to decode frames at 1080p resolution

Default x264vfw settings would have a max keyframe interval of 250, which is much to large for snappy editing, even on a faster computer. So if you use a smaller keyframe interval (lower, even 1 is "best" for editing), and --tune fastdecode, timeline performance will "feel" much faster. The problem is default settings are for high compression, not for editing. When you seek, the entire GOP of that frame you seek to has to be decoded before it becomes responsive. (But even on those "fastest" , editing friendly settings, it will still "feel" slow compared to an editing codec like cineform.)

And vegas shouldn't have any problems with any mpg file (assuming it's mpeg2 video). You shouldn't need to do that intermediate step

If you're going to use an x264 vfw intermediate in AVI use short keyframe intervals, like 6 frames, and no b-frames.

Putting avc in an avi container is always a bad idea. Use mp4 or mov instead. Also, stop using x264vfw and learn how to frameserve to a better encoder.
