Jerry and others,,
have you tried the Speedo plugin from Genarts for this?
My tests show it does a brilliant job, probably as good as Twixtor. It seems to have some issues though and I don't know if it's Speedo's fault or Vegas's OFX interface that's the problem. Either way getting it working and more importantly, getting it past beta so GenArts are selling it for us Vegas users would be a huge step forward for Vegas.
I'd love to be able to devote more time to this campaign but I don't have much need for this kind of feature myself and I think what Genarts needs to see is more Vegas users downloading the beta and sending them feedback to convince them it's going to be worthwhile them spending time getting it working right and offering it for sale.
In my opinion the most important tools added to Vegas in the past 9 years are the Elastique pitch shifter and, the YADIF de-interlacer. All that's missing is a good video retiming capability to get Vegas back to being as good as the competition.
"have you tried the Speedo plugin from Genarts for this?"No, but surely worth investigation. It's not that I'm in love with "Disable Resample", it's just that, imho, the Vegas resampling is so very unpleasing to my eye.

I use it all the time when mixing Progressive & Interlaced footage - and it does a fantastic job.

When I cam onboard with V4 the world was either 50i or 60i and Vegas's field blending was as good or better than any other software solution, in fact I think Vegas offered the only software solution and most in the industry were forced to use expensive hardware boxes.
With footage such as 24p and 30p to wrangle, the technique Vegas uses has fallen well behind the competition. I'd prefer the improvement to be something native to Vegas. Although Speedo isn't going to be outrageously expensive I do think such functionality should be within Vegas. Having Speedo as an option will be better than nothing and will avoid having to go outside Vegas, something that many are reluctant to do even if the tools are free.
One issue here I should mention is that Speedo being an OFX plug will only run in V10 and later and that's going to prevent some who might be the best to take up this challenge from participating.
Okay, turns out there is a public beta for Speedo: https://info.genarts.com/GenArts-Speedo-Public-Beta.htmlGenArts Speedo Public Beta[/link] I downloaded the software and have been playing with it for the past couple of days. While it seems to show some promise for both SloMo & adding motion blur, I've abandoned my testing as it slows renders down to a crawl - 30+ minutes for a 3 sec render to MainConcept AVC/AAC .mp4 on my i7 laptop.
The plugin seems to be focused on SloMo, but has a provision for adding motion blur for framerate changes.
I'm not quite sure how "Shutter angle", "Shutter Phase" & "Motion Samples" affect the motion blur renders, but I abandoned testing at this point because it became so cumbersome.
I don't have Twixtor but it's slower than AE's native pixel by pixel retiming.
Speedo has been around for a while for other apps, I think the only beta part is the port to OFX.
Here is an extreme stress test I did on Speedo some time ago.
By comparison here is what AE could make of the same footage:
Jerry,
Shutter Angle and Shutter Phase would appear to emulate the controls in a film camera.
Using software to create slow motion or change frame rate is the same thing. The software has to create new frames by estimating how every pixel has moved between the frames that the camera captured. Doing that requires a MASSIVE amount of computation, your render times are no surprise. For my tests I used standard definition stock footage just so the render finished before I expired.
No real need to do any more tests, even with a fire breathing rig all these class of plugs / tools are slow. Just by downloading the beta and registering you're telling GenArts us Vegas users are interested so hopefully they will devote more resources to it. They've done their best to answer my questions but are also quite upfront and said our market segment is toe in the water for them.
I've done some more testing here and want clarify my recommendations - just so folks reading my comments are not lead astray.
Recently, I've started shooting with a high shutter speed to improve the motion blur artifacts that occur when performing a "Rock Steady" stabilization via Mercalli V2. If I render this fast shutter footage to a different framerate, (to my eyes) "disable resample" visually improves the renders (regardless of whether they are stabilized or not).
However, if my source footage is at a low shutter speed, the source footage contains motion blur. While the stabilization looks like crap (a technical term), the smoothness of motion in the resampled renders actually look better (again, to my old eyes) than those with "Disable Resample" applied.
So, what's the bottom line? There's no one answer for everything. Best advice is to do some test renders on your project and see what looks best.
