VP20 Hanging on each use (never when rendering)

clarkerza wrote on 11/14/2022, 11:28 AM

Hi,

I realise crashes/software hangs are very subjective with many different hardware options and operating system bolts on etc but would really like to try and drill down to what is the root cause of mine. It's not new to my version of V20 but happened with V16 and V19 as well.
The rash symptom are, Vegas Freezes and then you get the blue spinning curser following by the Windows 10 OS Popup "Vegas has stopped working do you want to wait or..... etc etc". It never crashes when rendering just when generally using the software. I have never seen the "report the crash to Magix and attach the log file" which I have seen previously in an older version of Vegas a number of years ago.
I have an I7 8086K 5Ghz (8th Gen/Coffee Lake) 64 bit CPU, MSI Z370 GAMING PRO CARBON Motherboard, 32GB of RAM, RTX2080 Ti graphics with three monitors. 2 x HD and one UHD. It's not the newest system but it's still OK. I have tried all of the many suggestions from the Vegas Pro crash support videos from YouTube, but still it occurs. I do a lot of multi cam work with 3 video tracks sometimes but it's just hung now on one single track. I do tend to pop out the preview screen on the UHD Monitor and run Vegas on one of the HD monitors but it has hung with the preview windows being in the normal main software window.
Is there any form of log file I can take a look to try and see why it hung? I did look in C:\Users\<USER>\AppData\Local\VEGAS Pro\20.0 and the only file that was there at the time of the crash was VEGAS Pro Redo Buffer 2.tmp which I couldn't open.

I know this is difficult so don't expect any miracle advice here, but I find Vegas Pro so easy to use which is why I upgraded to V20 and would really love to stop the crash which normally happens at some point each time I use it.

Thanks in advance for any friendly advice.

Thanks

Andy

If you can use the iGPU I highly recommend it for stability in Vegas vs NVDEC decoding.

Try again after setting in Options/Preferences/Video your Dynamic RAM Preview max to default or 0

Thanks will do.

I also see that your CPU has an integrated GPU, the Intel 630.
Nowhere I can see it.
Normal it is the chosen default at FileI/O, is there a choice?
If not, you must give permission to allowe it in the BIOS to show up and use it after installing the latest driver version for it ( Intel gfx_win_101.3729_101.2114)

Thanks J-V I'll enable in the BIOS and install the driver and also set Dynamic RAM to 0 as well. Will let you know how I get on.

I'd test dynamic ram preview at the default first (200MB for older Vegas or 5% for newer) and then 0 if problems persist. 0 will reduce preview performance though can avoid artifacts when rendering especially when using GPU encoding.

That's really useful thanks.

To be clear about the use of Dynamic RAM Preview max.
These are the instructions from the manual:

" Using dynamic RAM previews

When your project includes compositing and complex video effects, you may not be able to preview your project at its full frame rate. If you prefer not to prerender your project, you can dedicate a portion of your RAM to cache video frames that cannot be rendered in real time.

Setting up your cache

From the Options menu, choose Preferences and select the Video tab.
Enter a value in the Dynamic RAM preview (max) box to set the amount of RAM that you want to dedicate to video previews. The maximum size of the RAM cache is displayed to the right of the control. If you reserve excessive amounts of RAM for your RAM cache, performance may decrease.
Click OK.

Building the preview from a selection

Select the region that contains the frames you want to cache.
From the Tools menu, choose Build Dynamic RAM Preview (or press Shift+B).
Each frame in the selection is rendered. Click anywhere in the timeline to cancel.
After rendering is finished, click Play .
The cached video will play back at the frame rate specified on the Video tab of the Project Properties dialog.If your RAM cache is not large enough to contain the entire selection, the selection is automatically adjusted to include only the cached region. You can increase the Dynamic RAM Preview max setting on the Video tab of the Preferences dialog to increase the size of the cache.

Clearing the cache or turning off dynamic RAM previewing

To clear the RAM cache during playback, you can resize the Video Preview window or choose a new setting from the Video Preview Quality drop-down list.
To turn off dynamic RAM previewing, enter 0 in the Dynamic RAM preview (max) box on the Video tab of the Preferences dialog."

Be aware that the amount of chosen Dyn Ram is not available for other tasks until you change the amount of reserved RAM

Thanks for this. I thought the dynamic preview RAM was just the ordinary preview window...so I've learnt yet another thing from this forum!! Thanks for this. No crash as of yet after I made your other suggested changes.

It's really handy for previewing things like transitions and Fx like morphs. Highlight a few seconds of the timeline and hit shift b.

Nice one Roger, makes total sense now.

What are you using for Morphs?

I used the Warp Flow transition in VEGAS.
