There are great YouTube channels (e.g. NASS) taking film footage from the 1910s, 20s, 30s, 40s and 50s and updating that video to modern fps frame rates, stabillising the video and in many cases colorising that historic video (with some weird results where often black cars appear as purple). A common comment on those YT videos is that it's like a time machine going back into the past - I couldn't agree more.
My current project is nowhere so historic. For the past week, I've taken a nearly 19 years old project of a tour of rural Switzerland (in 2007) which I would have originally edited in ULead Video Studio. Back in 2018, I began the restoration process by matching the video events in Vegas Pro to the base Ulead Video Studio render. At the time, stabilising the 720 x 576 video worsened the limited video quality, but in 2026 that loss can be offset in VP23 by using Vegas Pro's AI Upscale FX.
In Project Properties, 1920 x 1080 was set but the pixel aspect ratio had to be reset to 1.00.
I am now able to stabilise most SD video events in Mercalli 5 SAL (several but not many events were better stabilised in VP's native Video Stabilizer).
BTW, VP's AI Upscale was set to Sharp and Cutout was set to 0.500, 0.500,1.030 for the original un-stabilised via Merc 5 MiniDV video.
Rendering is yet to happen of the 50 mins project - but at the moment on the timeline it's looking good.
And no crashes in Vegas Pro 23 b302.
