[This is mostly solved now.]
I was a long time Vegas user that just upgraded from v14 to v20 - I was entitled to the non-subscription upgrade.
What a major difference between v14 and v20, notably in the (lack of) performance. The UI is much laggier, unusable in a stock state, compared to loading the same project on v14.
I think I have the worst of the performance kinks worked out though, but I'd like to know any other performance improvement tips I might have missed.
I spent my first week digging through this forum looking for performance tips, and came up with these so far:
- Turn off audio scrubbing with an obscure Internal setting (Pause Scrub = 0)
- Turn off all GPU acceleration in Display and Video preferences
- Turn off all legacy features such as Legacy Text
- Use Alternate High DPI Settings under Display preferences
- Avoid all GPU-accelerated rendering
- Assign more RAM and rendering threads under Video preferences
Fortunately I found that the one TTF font I use the most, something called "Square 721," no longer requires the Legacy Text media type to work. Also, when any GPU rendering option was enabled, this one project I had would constantly stop rendering at a specific frame, but after disabling all GPU rendering I could finally squeeze out a final video. Granted that project had almost all 4k source media and the final product was only 1080p, but it did manage, and at a render rate comparable to the same project on v14.
I'm going to try cutting one more video in a series I have. Maybe using fresh media on a new project, instead of importing a project from v14, will help speed things up.
I'll try to fill in my system details, source media details, workflow, and intended final product as best as I can. I'd love to make a project archive available for people to inspect, if it wasn't 100 GB in size.
System:
- Intel Core i9 10900 2.8 GHz, 32 GB RAM, 512 GB NVME OS drive, 4 TB hybrid drive for storage, all on a MSI Z490M mainboard
- BIOS settings adjusted to give the GPU 16 PCIe lanes ("Auto" would cause lag in some games)
- NVidia RTX 3070 Founder's Edition GPU, using Studio drivers and not Game drivers
- OS is Windows 10 Pro 21H2, which I tend to keep very clean - for instance I have Software Restriction Policy enabled and I run my apps as a non-administrator where possible
Software:
- VEGAS Pro v20 Build 214 (which I think is Update 1)
- Goldwave for audio editing
- Handbrake v1.5.1 for transcoding from Apple MOV to M4V AVC / AAC variable bit rate
Source media:
- Apple iPhone 11 Pro, either 1080p60 or 4k60, hence the transcoding to M4V
- NVidia Share captures to 1080p60
- Random static images, WAV audio, MP3 audio
I do admit to getting silly with the 4k source material. To reduce the pain on v14, I would turn off automatic proxy generation, and instead import all source media into the project, followed by triggering proxy generation for all media that supported it. This would take a couple of hours, after which editing was not as much of a pain. I turned off automatic proxy generation on v20 as well, with the intent of importing all sources and generating proxies as a batch.
If all else fails to improve UI performance, I'll consider replacing this PC, maybe even using a RAID-0 array of SSDs for storage instead of the hybrid drive. I'm thinking even of building a dual processor PC, just so I can have the 16 PCIe lanes for the GPU plus a dedicated PCIe x8 RAID card for storage.
