Video Preview is Lagging hard and no promised courses...

Hi, I bought a 1 year subscription to vegas post and I have 2 points that disappoint me the most.

I am new to video production, I have experience in some DAWs like Ableton Live. The first major complaint

that almost makes me want to cancel my subscription and switch to Premier is the Preview lag. I have a pretty powerful Laptop

Alienware 17 r4, which has Intel i7-7700HQ CPU @2.80Hz 4 core, 16 gigs Ram with a geforce gtx 1070 video card. Please tell me that is sufficient for basic smooth video editing. ive tried changing from high res to preview default even to making a clip proxy which makes it look very pixelated and horrible and it still lags, even with all of that.

the other thing that bugs me is that on the sales info page it is mentioned that i would get not 1 but 2 courses... i havent found a single one.

Can you please help me out here, I'm really struggling here. Thank you kindly.

@Egor-Poludo What kind of media (codec type) do you use in your time-line?

There's only this re training courses on the Product Page VEGAS POST 365 FAQ: "How do I get my online training? You will receive an invitation for the training via email a few days before the scheduled event."

Vegas recommends 16GB for editing 1080p, but 32GB for 4k video. Your GPU should be sufficient, however. The type of video you are editing, the settings of your proejct, all that stuff matters heavily when it comes to getting a smooth preview playback. Are you set to 32 bit mode in your project settings? If so, change it back to 8 bit. Unless you are editing 10 bit or higher video, there is no reason to ever use 32 bit mode. Also, try disabling resample in project settings, that can boost performance. Then, you want to make sure you project and media framerate, interlacing settings (always use progressive scan unless your media is interlaced), and resolutions match as closely as possible, you want as little conversion as possible taking place.

Also, go into preferences, and under file i/o settings, make sure your geforce card is set to be used as the decoder, and under the video tab, make sure it is also set under GPU acceleration there as well (you can try intel quicksync for both, see which works best for you).

You know, all this stuff sounds helpful but I have no idea how to do any of it. I am self "teaching" amateur. Any recommendations on where I can learn about all the stuff you mentioned? You are literally speaking another language as far as I can understand...

I do not know, how do I check that so I can answer you?

Youtube is a great spot to search for tutorials... just gotta keep in mind that the way they show may not always be the best way, so if you see more than one tutorial on something, watch both and cross-reference them to figure out the best way to go about it... or you can always ask someone around here how to do something specifically. With your knowledge levels where they are, I'd recommend starting with Youtube tutorials until you're familiar with the basic functions of the program, how to set up a project, etc... and you can also look up non-Vegas related video stuff like, "what is a codec?", or "video color space explained", or "video bit depth explained", etc... there's an infinite amount of knowledge out there to be gained, as long as you take it with a grain of salt and cross-reference it.

As you dive deeper in the wormhole, you'll hear terms that fly over your head... pause it, look those things up, learn about them, then get back to where you were. That's how I go about learning... your mileage may vary. Eventually it'll all start to make more sense, and you will find yourself saying "what is that? I need to look that up" much less often.

Creative Cow has some tutorials as well, but I primarily use Youtube.

Every single user of Vegas hits some sort of "brick wall" with preview. The main "Fix" for all of that is a BEAST of a machine, now meaning THREADRIPPER, (or Intel equivalent) Total RAM, SSD drives and GPU are secondary to the CPU, all play a lesser role (though you certainly don't want any unnecessary bottlenecks).

Now, if you HAVE an AMD TR CPU, (or close) To go to the NEXT level, add a truly TOP END Graphics card = AMD VII or Vega 64, OR a 2080ti. Those are proven difference makers on playback. Lesser cards, not so much. GPUs EQUAL to the aforementioned will be coming out, hopefully soon, and should more affordable, so look for those, but MUST BE IN THAT CATEGORY.

IF none of that is within reach, people mitigate the lag by several strategies. First, optimize the Operating System, then you want to play back without effects, sometimes, or use RAM preview. (see Youtubes on RAM preview).

There are lots of Youtube videos on Vegas Lag. Some are "OK." Remember, most of those are in the "mitigation" category, NOT elimination of lag. Again, the LAG destroyer is a super boffo CPU, as I mentioned above.
