Actually that is a VERY important aspect when dealing with preview!!!! I had the same question as to why I had no better preview on a GPU upgrade and John R. here on the forums instructed me to make sure that was disabled and my previews have been way better. I edit 4k and below with smoothness I never had before.
The question to why you are not getting better results is likely the older code Vegas is using for preview. I have great luck with previewing 4K on a Radeon 290X, likely the GPU architecture is newer than Vegas can utilize.Here is a clip from that thread I mentioned…
[Scott Francis] “I have just started to disable resample on the 60p clips. That does seem to help a bit with preview. ”
It helped me more than a bit. I went from 6 fps back up to 29.97 fps during transitions. If you don’t disable resample, Vegas Pro will try and blend frames on the fly to conform to the projects frame rate. Other NLE’s would force you to conform your video first. This isn’t a bad idea. Just because Vegas Pro lets you throw mixed frame rate clips on the timeline doesn’t mean that you should. 😉
[Scott Francis] “So my main question is WHY is preview still so CPU heavy when we are utilizing GPU preview? This doesn’t seem to be logical (at least in my mind) as I have been chasing this end of the rainbow since SVP11!!!”
It’s about striking a balance. The GPU doesn’t work on it’s own. It is a co-processor which means that main processor (CPU) needs to feed it work. Perhaps an 8-core can feed the same GPU better than a 4-core can and keep it busy. There is a lot of setup and breakdown of data before and after the GPU does it’s work and the CPU needs to do all of that. Think of it this way… have you ever been so busy and someone says to you, “why don’t you delegate that to someone else” and you say, “it would take me longer to explain to them what to do than to do it myself”? That’s the relationship between the CPU and GPU. The CPU needs to do work to use the GPU. It’s not free from overhead and sometimes it can even be slower because the overhead is greater than the computation.
[Scott Francis] “Also, how useful is multicam editing in SVP vs the way I am handling it?”
Multicam in Vegas Pro assumes that everything is synced up correctly before you start. We have tools at VASST like infinitiCAM and Ultimate S Pro that take a different approach using markers for camera switches. Here is a video of infinitiCAM that you can download and view (sorry it’s in WMV format). This will show you the workflow.Hope that helps

Have you disabled resampling for the video clip properties?

The G30 has a small eye cup. I use it often instead of the LED screen, especially outside in bright light.

Looks like Canon has all 3 in their refurb store.

I do a TON of plays and stage stuff. Here is a link to some examples. All but the Joshua Tree demo are using Canon G30 and G10’s. You would get similar results with the G20.
They also have a LANC remote connection which is really important for me as well. I control most of these remotely with PS3 controllers for Pan/tilt and Zoom/focus, etc.https://www.mindseyeaudiovideoproductions.com/video-samples/live-production-examples/

So many recorders (Atomos, Blackmagic, etc) record in Pro Res and the current limitations of how many clips you can use is a real kicker. I really hope this is addressed.

I have 3, Vixia G30’s and 1 G10. The G10 is the same as the XA10 Pro version (only difference are the XLR connectors).
The G20 is a VERY minimal update tot he G10, and I didn’t go there. I waited until the G30 came out and LOVE IT!!!
You can shoot 35Mbps MP4 in 1080 60p. I use them with my Blackmagic ATEM switcher for my live and IMAG gigs and also with most anything else I shoot. LOVE THEM!!!! Good in low light (if you work with the settings and know what you are doing), footage is really nice and edits really well in Vegas. It also has good connections (LANC, HDMI out, Headphone out, Iris, Zoom and focus as well as numerous (I think 5) assignable buttons. It IS somewhat menu driven, but not horrible to navigate.
They have the new G40 out, which I will not buy. It has an updated sensor, but not worth updating to with no 4K.If you are going to purchase, I would NOT get the G20, go with the G30. They have come down in price since the G40 has been released and the updated 35Mbps is REALLY worth the difference.
If you are looking for XLR inputs here is how the variations go with prosumer to pro numbering
Prosumer Pro
G10 – XA10
G20- None
G30 – XA20 (XA25 has HD-SDI out as well)
G40 – XA30 (XA35 has DH-SDI out as well)Hope that helps!

WOOHOO!!!

Sorry, I meant zooming in vertically…

Right click on the audio – Goto “switches” and click on “Normalize”….this will bring your hottest level up to 0dB and also let you see the waveform better.
Do you have Sound Forge as well? Sometimes you may need to go into the audio file and “chop off” some of the high level (if there are clicks or clapping/etc) that are NOT important aspects of the audio you need, to allow the visual representation of the wave to be big enough to sync with your other audio.
Also, zooming in horizontally will give you a larger view of the audio as well.
Good luck!
