VP17 General Performance

joost-berk wrote on 9/20/2019, 2:57 AM

The last two days I spent my time editing a music video. 25% of the time I wasted with restarting Vegas Pro 17 after crashing. What is it that I do wrong? My setup is a Win-10 pro with a 32GB RAM, Core-i7 7800, Intel SSD (clips are local), GTX-1080 with latest Studio Ready drivers. A Decklink 4K for viewing, X-touch for external control and a M-audio soundcard on ASIO. For this project I worked without any plugins, video sources are: XAVC-S (4K) and XAVC-L (HD) all in 25fps. I used 20 tracks and about 150 clips.

It already goes wrong with opening the time line. This takes insanly long (like minutes). If you think that Vegas is ready loading, then it even needs more time to load. Something I have never experienced in VP16 and earlier. Vegas will crash in normal time line playback, splitting multiple clips at once or undo-ing. I tried working with proxies in low quality, but after a few minutes the preview got black and the progress dots underneath keep stating that it's loading. Besides this crashing behavior, playbacks stutters on every start of a clip. If I play longer parts it gets up and plays normaly. But with all the short bits in a music video, it feels as it is constantly stuttering. Even with draft video preview quality it does this. Entering the end of editing, cleaning up the timeline and starting to do just coloring no crashes occured. Only the poor playback rate. But during editing it was a nightmare.

Don't get me wrong, the Vegas-team does a great job! I am a Vegas fan for years and a user since version one. But this is something I never experienced with earlier versions. If I had made this project in VP16, things would be more stable.

Is there something that I can try, or just wait for the first VP17-update?

What are your settings in Options/Preferences/FileI/O?

Those are default. So "Enable hardware encoding for supported formats" is checked. "Enable MKV reader" is unchecked.

And the hardware decoder to use is: NVCodec

I think you mean "Nvidia NVDEC", so it is called with me and it helped me enormous to play 4K HEVC 50p Files of my GOPro 7 without proxies in the previewscreen set to Best/Full at full speed with a constant 50fps, while before switching on that setting they played stuttering with 1-2 fps.
My RAM preview is set to 0 because I never use that option.

You are suffering from the dreaded thumbnail bug. Vegas 17's first release has a bug where, in projects that have lots of media and therefore lots of thumbnails displayed on the timeline, the thumbs load slowly, which makes projects take forever to load and causes Vegas to freeze often when you do anything that makes Vegas have to redraw the thumbs on the timeline. The team is well aware of the issue, and it will likely be fixed in the update they say is coming very soon, but in the mean time, go to preferences, click the video tab, and disable or reduce the timeline thumbnail display. This will get you going until the update drops.

@fr0sty Thanks for the explanation, I just downloaded the update for VP 17 and all seems better now. The thumbnails in large projects load as much faster. Als I checked and my "File I/O" was on the Intel encoder, and changed that to the Nvidia. This made a lot of diffence in playback any XAVC file.

One other thing that came across using the Nvidia Encoder for File I/O is that it uses all GPU-RAM. This becomes a problem when using Neat Video Reduce Noise V5 for example. Because this plugin works beter with GPU accelleration. Even when I put Neat Video into "CPU only"-mode. I couldn't finish a render with this combination. Therefore I needed to switch back the File I/O to Intel QSV in order to complete my render.

From my experience last night with the most current build, Dreaded Thumbnails still seems to be an issue. Vegas kept freezing, stumbling, choking, gasping for air, turning red, and then became non-responsive when I tried to load an ALL-I, 10 bit, 4:2:2 video file, approx 1 GB, 45 seconds long. Some clips it would let in, and some it would just freeze up. The same clip in Resolve would be okay. Once I went to: Options> Preferences > Video > and disabled Thumbnails to not appear, everything worked perfectly in Vegas and Vegas actually handled the clip much better than Resolve did. So, all I can say, is that this still appears to be an issue as of 11-22-19.

@karma17 Thanks for your feedback. It is something that I will test tomorow. The fact is that the thumbnails are offcourse a verry nice feature in Vegas. It really speads up my editing workflow. I don't want to loose this. I've seen that in the latest build, the extreme lag is gone. So the situation for me is good enough. But if the thumbnails are such a big perfomance eater. It is a good thing to turn it off when things get tough.
