Slow Motion

Roger Bansemer wrote on 10/9/2022, 5:55 AM

I'm using Vegas 20 subscription and would like to know if the slow motion in V20 is equal to or better than Twixtor and ReSpeedr which I have purchased in the past as those programs are somewhat old at this point. Any thoughts?

It's going to depend on the media that you are using, how much the video is being slowed down and what settings such as optical flow are being selected.

Since you have Twixtor (which I don't have) and ReSpeedr (which I do have), have you done your own testing of slo-mo-ing the same video event using VP20, Twixtor, ReSpeedr with all the available settings in those programs in order to form your own opinion? With ReSpeedr, I've had some .mp4 slo-mo perform better with one optical flow setting but another .mp4 event (from the same camera) to perform better with another optical flow setting.

With Vegas Pro 20, I've recently done some minor slo-mo (circa 80%) and haven't needed to go to ReSpeedr - but that project hasn't been rendered as yet.

It's much like stabilisation - the best stabilisation result can occur using Vegas Pro's stab plugin, one of ProDad's Vegas Pro Mercalli plugins, ProDad's Mercalli standalone program, or Mocha Pro's stabilisation.

Similarly with slo-mo, I don't think that there's a 'best size fits all'.

Thanks for the feedback. I haven't done any testing myself as I thought I'd get an opinion or two before going to the trouble and time to install those programs only to find out there isn't much of a difference. After what you said, I think I'll just stick with whats within Vegas.

@Roger Bansemer Here's a comparison between the free FlowFrames and VegasPro19b550. If slowmotion has been updated since then it will show in release notes. I don't think it has. I don't have twixtor

They both give artifacts, Vegas more so, especially around the edges

@Roger Bansemer No, its not on par with Twixtor..... Twixtor is simply the best in this department, and what i still use for perfect slo-mo tasks.

@Steve_Rhoden I thought I should fact check that strong claim, so re-installed and updated Twixtor. It looks to behave similar to FlowFrames, and is far from perfect. The original footage does contain motion blur which optical slow motion has the biggest problems with. The same video with faster shutter speed would likely give better results
