I have trimmed the ends of all clips to remove the end wobble you mention, adjusted colour with levels filter, added stabilization (legacy stabilizer - my favourite). All with no crash or freeze. I can scrub the timeline by grabbing the marker (not the head) back & forth fast or slow - no freeze. I can use pan/crop to level the second clip at the end with no issue. What else can I try that has given you a problem?

My settings are, Dynamic ram 0, rendering threads max 4 (my i5 has 4 cores and no hyperthreading). I will leave it open on timeline to see if I have any issue after 30 mins or so.

Right - we have a crash! Tried to open the pan/crop on second clip - freeze not responding. Opening V18 and going to the clip I can open the pan/crop OK. Then plays OK, added fade out on last clip OK. One thing I have noticed that moving the curser can lag. I loaded one of my projects and the curser showed some lag, this went away when I restarted V18 and loaded my project again. The crash seems random as I can open pan/crop on any clip with no problem. Also added a title.

Walter can I send you four of my clips to try. I can send via airbridge which sends you an e-mail link to download from airbridge. PM me your e-mail if you wish to give it a try?

Also added colour grading via the panel - OK. No further issues so far with pan/crop.

I got it to freeze by changing from best quarter to best full. restarted and used best full it played OK. Random freezing. Again trying different preview modes got it to crash when best full.

Your laptop seems better for cooling than mine, but if you notice CPU speeds dropping dramatically while it's still doing work, consider installing this free program and looking up a guide for how to configure it.

@RogerS
I don't have a laptop, but a desktop, I haven't noticed any heat problems so far - has very good ventilation - because the freezing occurs even during "normal operation" - without the processor performance or the GPU coming close to a limit.
I'm glad nothing bad happened to your laptop.

I'm at a loss, start project and play repeat and change preview while playing through all options many times - no freeze! there must be a memory leak somewhere.

I don't think its anything to do with heat.

@andyrpsmith

Thanks for your extensive tests!
I'm not even at as intensive editing as you've tried, but only with the rough cut, where I shorten the clips and arrange them in the desired order.
For me, too, the freezing and crashes happen randomly and not at certain points in the film or during certain actions.
Your realization that the freeze mostly happens on "Best Full" is interesting.
I tried to set the project settings to 1920x1080, and it froze there too.

I will send you a PM with my email address, as you have offered.
Thank you very much for the time being - a really great community here.

How can I detect a memory leak?
If I watch the Task Manager while working, the graphics in the RAM draw an almost straight line at around 11-12 GB - even when it freezes - no change - see screenshot that I just made.
I added transitions between the clips, stabilized them (new method), and quickly scrolled through the project.
After about 3 minutes there was no more fun.😟

I don't know but if memory is being overwritten within Vegas then I guess it will freeze as it cannot access the data. You have the links now to Air Bridge download.

Just chipping in that I have the same issue editing 4K/25p XAVC-S files from either a Sony AX53 or ZV-1. After a short while editing, the computer freezes.

My only solution is to make proxies for the lot (which I seem to recall are MPEG-2?) and edit with those, then let Vegas swap them out on render.

And as someone else mentioned, HD files from the same camcorder seem fine.

Cheers

David

@David Johns
Thanks for the confirmation, very insightful!
I would have planned that as the next test - either proxies or conversion to another file format. You have spared me that now.

Which would interest me as we have pretty similar equipment.
Which I / O setting do you have?
Which Dyn. Ram setting?
GPU acceleration - if so, which ones?
so4compoundplug.dll disabled?


PS: @VEGASDerek
If it is now confirmed that these 4K/25p XAVC-S files from either a Sony AX53 or ZV-1 are causing problems on several different PCs, could the Vegas team take a closer look at them?

Yes it would make sense for Vegas team to look into this if possible.

I wonder if this is 4K25p issue. That's not a format I ever work with, so I wouldn't have seen problems until now.

I haven't tested 373 much, though, so I'll do more with my regular Sony 4K24p files and see if I still get errors.

FWIW, I used best/full, so4compound is on, GPU is NVIDIA 1050, file i/o is auto (Intel HD 630), dynamic ram=200MB.

In my case I think the heat may be a symptom of something going wrong with Vegas- not the problem itself. I normally use 4K24p clips and haven't had bad throttling, the Intel GPU at 100% and then a memory leak with soaring ram usage. Will do some more testing with my usual files to see if this is an issue with recent builds of VP 18 or these particular Sony files or 25p in general.

We downloaded the project and sample clips (C0060.MP4, plus the other three) and tried both the files individually, and the project on a range of machines (from i7-6700 to i9-900) using b373 and default preferences (so so4compoundplug was enabled for AVC decoding, and using the Intel QSV decoder). We could not reproduce either the freeze or a crash. This was using both the latest Intel drivers (27.20.100.8853), and an older set (26.20.100.7642). The project will exhibit slower playback on certain machines on account of using some of the more intensive FX, such as Color Grading - removing those brings the speed back up to full frame rate. We will continue to try and reproduce the problem, but we would appreciate any more information to help us in this matter.

As can be seen above I had some issues when first loading these clips, some lag and difficulty in dragging the ends to shorten the clip length. However I was able to overlap, do levels filters, stabilize - all OK. I saved a project and played about with the clips for a while all working OK. I then clicked on pan/crop and had a freeze. Re-launched V18 and all was well for a while. I then changed the preview while playing from best quarter to best full and it played for a few sec and then froze. Re-launched V18 and all was well, I can change all preview settings while playing all OK no freeze. I have the project open all day and cannot get it to freeze again, it moves snappy along no lag or any problem. I have found this with a number of projects - new clips may freeze randomly and then over a few hours of using V18 settles down and is OK.

Also I sent some of my clips from my Sony AX100 XAVC-S 4K 25p, these have been working really well in my holiday project for last few weeks no freezes at all yet Walter had these freeze on his system after a few minutes. Happy to provide some clips if this would help?

Update: I went back to my regular 24p Sony AVC footage and after putting an hour so of 4K clips on the timeline, adding a LUT, playing back at best/full and trimming, skipping around while playing, couldn't trigger freezes or crashes with 373. I was able to get the laptop to throttle due to heat, but after quite a long time playing back files, so that doesn't seem specific to Walter's files.

I tried Walter's files again skipping around while playing back at best/full and shortening clips during playback as before. I didn't get any crashes for ~30 min. After the laptop started power throttling, trying to play different clips resulted in a freeze (not responding). So for me, I think issues are likely temperature related and perhaps not due to the file type or 25p. Hopefully others can help narrow it down.

Are you using CPU-Z & GPU-Z to monitor temps? I use GPU-Z quite a lot to see what my GPU gets to in some game bench marks. Normally never above 70C for GPU.

@VEGASHeman

I recorded the RogerS project with my video files using OBS.
At the beginning I showed the Task Manager with the resource monitor, then an overview of processes, performance, app history, etc.
After that the project was started with a loop and let it run through - after all, I used the Shuttle Pro V2 to scroll back and forth - until Vegas Pro was frozen.
Unfortunately, no crash report could be sent.
