May be purely coincidental but I notice that the event ending at 31:30 on your timeline (which is exactly 94% and where your render ended) is highlighted. Is there anything special happening at that point?

Cheers, , Robbie

last suggestion:

take 2 HDDs and use only the non-sys one to read/write all media.

Thanks for your replies,

This program has crashed pretty much from day 1, when it was a clean install & everything was set at default,

It was then i started going through the comments on this forum about help suggestions, dynamic ram preview was orig at default, i tried at 0 as some suggest, i tried at several different sizes, Render on this was done with Nvidia but i've had it set at Intel, i've tried it when it's been running a while & prob getting hot but also first thing in the morning when it's cool no change, there's always a chance it will fail, This was 1920x1080 HD MP4, the same as the project & Render settings, nothing special at 31:30 on the timeline, just a cut + 12fr crossfade, I'm sorry Yellandkeil, i don't understand what you wrote? I have msautosave set in Internal to 3min interval, a lot can get done in 3mins though but i found setting the saving more often interrupts Vegas workflow, where do i find 'live save' ?

like i say thankyou but your replies & questions is exactly the point of my orig comment, on other's comments i see the same questions, 'what ram' 'what GPU' 'what media' 'what project settings', I've tried many different combinations with no luck, you can pretty much guarantee Vegas will fail in some way during creation or render of a project, so i've started looking elsewhere, i downloaded the trials of Davinci resolve, hitfilm pro, adobe, I went on their forums & the questions on there are 'How to', not why does the program keep crashing like here in Vegas'.

Those programs play added transitions, effects etc without much problem, Vegas won't even play an unedited clip at Best-Full in the preview!

I do like Vegas, i bought it because it has a similar layout as Magix Movie Edit Pro that i've had for 16yrs & eventually i wanted more but i would like it to work without the unreliability always in mind & not have to fine tune it just to get the simplest jobs done,

Part of the reason for this post is like i say i do like Vegas but I’ve just bought a better more powerful PC, AMD Ryzen Threadripper PRO 3975WX 3.5GHz 32 Core , 256gb ram, GeForce RTX 3090 SUPRIM X 24GB OC GPU, that new PC will be coming in a wk, I Have Boris Continuum 2021 OFX & Mocha Pro 2021 OFX for Vegas Pro 18, I also have a Samsung s21 Ultra phone that i film my work with, that will do up to 8K video. , i’d like a software video editor that works, i'm going to see how it performs on the new pc but i'm seriously considering whether I'm going to stick with Vegas,

@Former user
We need the Info of your Error Report with selected "Show Problem Details".

I'm sorry Yellandkeil, i don't understand what you wrote? I have msautosave set in Internal to 3min interval, a lot can get done in 3mins though but i found setting the saving more often interrupts Vegas workflow, where do i find 'live save' ?

@Yelandkeil means that you should install or connect a second hard disk for the data of your projects.
Only the programmes should run on the system disk during video editing.

You can find "live save" under Tools / Advanced Save.

By the way - this is a user to user forum - it does no good at all if you constantly complain to us about what doesn't fit.
Those who actually want to help you only use up more of their precious free time.  

@Former user ... assuming that it is you who has been posting on BorisFX's forum recently about the same issue, I noticed that your media is principally phone video as per:

I have a Samsung s21 Ultra phone that i film my work with,

I am not sure if this has been covered in any other posts on this forum about your troubles with Vegas Pro, but there is an extensive history over the years on this forum about many who experience great difficulty with using phone footage in Vegas Pro. The reason for this is that iPhones and Samsung phones mostly record in Variable Frame Rate (VFR) rather than Constant Frame Rate (CFR). Vegas Pro does not handle VFR very well and the most common recommendation has been to first transcode the VFR media to CFR via a transcoder like Handbrake (or others) and then import the transcoded media into Vegas Pro,

If this has already been covered and addressed in other posts, please disregard this comment.

Vegas doesn't inherently crash, though for you it may well have. It's a combination of media, hardware, software, etc. That's why the details matter. Your experience isn't the standard and solutions that may help others may not help you at all.

The VFR issue is probably your main one.

If you render with NVENC you need to turn dynamic ram preview to 0MB or you may have it fail during the render (sometimes I get away with it on 200MB but it depends). I also just do CPU Mainconcept renders for a bit better quality and guaranteed stability. [Or x.264 through Voukoder for my final renders. Compact file size, fast and stable.]

FWIW I've also tested Resolve and 17 has stability issues, especially on the audio side.

I've been through a similar experience in the past searching through discussions and adjusting various settings in Vegas to eventually reach a point where I wasn't seeing consistent crashes.

The one setting adjustment which finally worked for me was under the PREFERENCES>VIDEO tab and that was to set "GPU acceleration of video processing" to OFF.

Vegas defaults to your video card's GPU for that setting which seems to make the most sense for best performance, but for whatever reason on my system it causes Vegas to crash frequently whenever I start doing any kind of video FXs/Processing within Vegas. I can edit/playback video all day without a hiccup in Vegas with that setting using my Nvidia GPU but as soon as I start working with any kind of video FX processing and that default setting is set to use my onboard GPU, I will experience crashes every 10 to 15 minutes. You mentioned you were doing some "Title" work when you experienced frequent crashes which sounds like video processing to me. I would try turning that setting to OFF as I have shown, and see if that helps. It worked for me, it may work for you.

What's frustrating for me when I try to make sense of this setting, is that it is a setting which seems to have a default for the best system performance but every other setting within Vegas is defaulted for best system compatibility. As a comparison analogy example, Vegas also defaults to "Microsoft Sound Mapper" for your audio card's driver setting since that's the setting every system has in common but anyone that has ever done serious audio work in Vegas knows the MS Sound Mapper driver setting provides the least amount of system performance while working with audio. The ASIO driver and even the "Classic Wave driver" sound card driver selection settings provides better system performance but this is not what Vegas defaults and is often a setting after adjustment can cause havok if your sound card's ASIO or Classic Wave driver is poorly written by the sound card manufacturer. Someone with a better understanding will have to explain to me the reason the GPU acceleration is set to your Nvidia/AMD GPU by default instead of set to OFF, since from my limited experience when working with video in Vegas, that's the setting that seems to cause the most grief in regards to compatibility where things just crash with no explanation.

Reset Vegas.

If you render with NVENC you need to turn dynamic ram preview to 0MB or you may have it fail during the render

I agree totally with this. It has been a recommendation for two years or so to set dynamic ram preview to 0MB for rendering with NVEC but leaving it at 0 all the time causes (for me at least) random crashes during editing and previewing is not smooth. Clearly this setting has more effect than just on previewing. It's high time this was sorted once and for all.

Hi folks, sorry to bring this back up but thought I'd give you an update & apologise again if i seemed on a bit of a rant, it's frustrating when you try all options available & still can't seem to find a solution to crashing, Sorry.

Anyway got my new PC, programs on one hardrive all media etc. kept on other drives. specs should be in my signature, I did try other editing software before buying the pc but most either created too big a file on export or were too slow to do it, Vegas won hands down on both of these, so like i said I do like Vegas, have stuck with it & have upgraded to 19 👍

I do understand it struggles a little with phone footage but the biggest thing i found that was causing crashes was the pre-edited/exported/rendered clips i was adding to the timeline were rendered with the Magix HVENC/AAC & had HEVC at the end of the file name in Properties, I switched to Magix AVC/AAC, these files have AVC at the end of the file name in Properties, (just like my unaltered imported phone footage), these play with no problem at all,

Thankyou @RogerS & @walter-i. Live save has saved me quite a few times as Vegas still does crash or freeze but I think some of that is me asking too much too quickly or changing my mind & cancelling before Vegas has had time to process, not all the time tho, sometimes it does just freeze for no apparent reason but Live save recovery is quick & no editing is lost (maybe just the last edit) 👍,

Dynamic RAM preview i found doesn't seem to make much difference when changing the size of it apart from changing the amount in the timeline that i can build a dynamic ram preview, that was the same with my old PC i think which had 64GB ram.

These 2 pics are what Vegas is set at & my render choice at the moment, I can export a 30min 4K project of maybe 20 clips in about 20mins-ish, In the last few mths I've uploaded about 40vids to YT, each 20-30mins long 👍

Thanks for your help & suggestions, I know you're all busy & do try to help where you can,

Can you also share a screenshot of preferences/ file i/o? If HEVC is causing issues try the legacy decoder (or vice-versa). It might also be an issue with how the GPU decodes HEVC, so try the new drivers. (help/driver update)

Did you export the NVENC clips from Vegas or another program like Handbrake? In general if you are going to be rerendering things I'd use an intermediate format (like ProRes) so as not to have compression artifacts. At the very least use a software renderer that's generally higher quality than the GPU hardware encoding (i.e. Mainconcept and not NVENC).

@RogerS Thanks, is this the pic you wanted?

No i don't use any other program to pre-render etc.

I did try several combinations using HVENC legacy.. but to be honest i just don't use the Magix HVENC/AAC anymore, I'm quite happy to use the AVC/AAC one, & the majority of things are still at their default settings, rendering is fairly quick, pic quality is good & Vegas is a lot more stable than maybe i made it sound. 👍

I'll have a play around with the ProRes but i just thought i'd share an update n say it's a lot better with AVC & I'm a lot happier with it 👍

I keep the Graphic drivers up to date, so i presume these two with the same no' are the same?

Over the last few months I've read many comments on here about Vegas crashing, there's many 'help' suggestions, put this setting to this & turn off that, check your drivers, it's windows update that's the problem etc. I've tried pretty much every suggestion, why should we have to do that just to make the program work just with regular 1920x1080 video clips. none of my other programs have problems like this,

Tonight i've been working on a very simple 30mins-ish video, several clips with just a few pics & titles added. i've constantly saved because i know it will crash which of course it did several times, i also have auto save on for the same reason, & then when relaunching it might have lost some of the titles, It should've taken me maybe a couple of hrs but more than 6hrs later i finally got a full video, put into Render out, 24mins later with only 1.5mins to go it Stopped working, this is ridiculous!

It would be awesome to see what happens on you PC... but it is impossible to find it without a comment or your name in the description of the screenshot. Maybe next time

In the error report box, put your forum username, and your email address in case the team needs to follow up with you.

@VEGASPascal I'm sorry , i saw this earlier but still can't work out your comment, Awesome to see what? & what are you trying to find? I made that screenshot back in May on my old PC

& @fr0sty what error report box? I haven't reported an error, i was just giving an update to say I'm a lot happier with Vegas now,

Sorry i've totally lost what's going on here now. 🤷‍♂️🤔

💡! if you're ref to the Problem report in the screen grab, i get so many i rarely send them in, never thought anybody would ever look at them.

I'll fill out the box next time 👍

The file i/o settings look fine. It's using NVDEC (NVIDIA) to decode and perhaps there are some issues with HEVC decoding. But since you're not using HEVC anymore that's fine.

The driver looks good as it is the latest Studio driver.

For the problem report, definitely send them in! If you include your email address or forum user name you might even get a reply if there are more questions. Without that nobody can troubleshoot your issue.

Thanks 👍
