That way the preview will not be bogged down when using cut out function in Upscale. I think a possible solution is for Vegas to not do AI processing until render time. Thanks again for testing in both Vegas and Resolve. I definitely look forward to future improvement in crop/scale.Ĭan compare Vram use between the 2, Vegas is on the high side currently. Upscale sharp works ok when I upscale a video but I can't use it as a cropping tool at the moment. I can't believe I added Neat on top of it. I just noticed my ram usage was about 26 GB doing Upscale sharp crop render. Was the test done as cropping in or upscaling the whole media? I tested cropping with Upscale smooth vs regular Pan/Crop and it didn't look like the sample above (with correct settings as in the big note). I just want to be able to crop in without losing too much or at least better quality than bicubic. Yes I definitely did lol! Especially after seeing the stuffs that Stable Diffusion is doing with AI. Upscale only added ever so slight contrast but no new detail added at all. I just tested cropping with Upscale smooth and regular Pan/Crop. I think it's using the AI models, but uses less Vram and processing power, and doesn't seem to do much. We know that as time goes on, the developers will hone the "smart filter" process to make it more automatic, but right now it's kind of superimposed on the old technology that Vegas once used. If you're not getting results like this from a 2.5x upscale from interlaced source, your "smart" upscale filter may be defaulting to "dumb" If you overlook any of these steps, Vegas will default to "oldschool" bicubic scaling, which is not what you want.(If I've missed the mark for Vegas 21, or left something out, I welcome being corrected.).The Upscale Effect must be applied at the Media Level, or at the Event Level, Pre-Pan/Crop only.The Project Properties must be set to exactly match your new Output Dimensions, not your Source Dimensions.That is a specific setting in your Video Preferences, it is not trivial. GPU Acceleration of Video Processing must be turned ON.Despite everything you read and hear on the internet, AI is not Alchemy.īig Note: The reason you aren't seeing the improved results you want with Upscale "may" be due to one of the following reasons: You may be simply hoping for a little too much despite the promises of AI. Keep in mind that all Upscaling is a destructive process. This is as true with paid solutions like Topaz, as well as with Vegas. I wouldn't mix conventional kernel filters and the Sharpen AI model under any circumstances. That model is almost certainly the "1,000 pound elephant" in your room again, I suggest respectfully that you start with Vegas Upscale (with Smooth, which is default model), preceded in the filter chain with a very conservative Unsharp Mask Fx, confirm that you have stable renders, examine your results, and add to them conservatively It has been changed, but is still profoundly system-intensive, and I am unable to use it on my i5 system. The Sharp Model in Vegas Sharpen Fx, in and of itself, was unstable and unusable when it was first introduced. I hope this issue can be fixed or maybe Vegas team can suggest ram amount to use Upscale sharp reliably? Is it true that the smooth mode doesn't use ai model? I was thinking about getting more ram but didn't want to encounter the same issue even with the larger ram. I checked my ram usage and noticed that the blank frames happened as my ram usage spiked from around 31GB to 32GB before dropping back down. One time I was able to get it to render with both Upscale sharp and Neat and got some blank frames. The performance will absolutely tank if Vegas doesn't crash because Vegas is allocating too much data to VRAM, it then leaks out into system memory and that's noy how GPU's are supposed to operate (especially Nvidia GPU's) This is true for you and me who only have 32GB of ram, it may not happen if you have 64GB or more, not sure. I haven't tried Upscale denoise model yet and how it compares to Neat. I was using the sharp model and didn't see apparent noise reduction happening so I used Neat as well. Neat is called a kernel level filter, which are about the most computationally intensive out there - except for AI modeling, such as Vegas Upscale, which has its own denoising.
