Prodad Mercalli 5 Pro Plugin works only in preview

Hello,

I tried to stabilize footage from my Sony FX3 video camera: 4K 50p 4:2:2 10 bit HEVC 200 Mbps in Prodad Mercalli 5 Pro video effect plugin (OFX) in Vegas Pro 23. I analized the video, but stabilization is only well in preview, during playback in Vegas Pro 23 (latest build). When I render this stabilized video in VP23 to Voukoder to HEVC, the video is still shaky.

Here is a link to raw video file:

I have Nvidia RTX 5090 Tuf Gaming (GPU) and Intel Core 9 Ultra 285K (CPU).

Can you check this file at your side?
Can you help me how to keep stabilization effect also in rendered video file, not only in preview in VP23?

VP23 Prodad 5 Mercalli Pro OFX specification:

Version: 5.0.504.1
Host: vegas230 [23.0.0.302]
NLE: ????
Plugin-Type: VEGAS
Status: Activated

Regards

Marcin

I've been quite happy with the results of Mercalli 6 OFX using the trial version in Vegas Pro 23, so I've just used the plastic-fantastic to purchase it today. It's still 30% off but when that offer ends isn't given on the ProDad website.

Yes, I confirm it too. I purchased Mercalli 6 OFX few weeks ago and it is good with stabilizing footage. I stopped using Mercalli 6 SAL.

@Dexcon

I have been wondering if Mercalli 6 OFX is faster with analyzing and during rendering when it is applied compared with Mercalli 5 OFX or 4 OFX.

I'm not sure mainly because the era in which I used Merc 4 for Vegas a lot was on a much older computer and with much earlier versions of Vegas Pro. I did try Merc 5 for Vegas as a trial but found no difference between it and Merc 4 for Vegas (keeping in mind that the leap from Merc 4 SAL to Merc 5 SAL was free because there were no new features, just technical changes).

BTW, I've just rendered a short length of a 9 mins project with lots of other FX (inc BCC Flicker Fixer) along with Merc 6 OFX, but I had loop selected in render options so only about 30 secs got rendered. But the good news is that stablisation using Merc 6 OFX worked well.

From all stabilization tools I tested and compared (Vegas stabilization, Mercalli 4 plugin, Mercalli 6 OFX trial, Mercalli 5 & 6 SAL) they were easily beaten in analyzing speed and result by the stabilization of Davinci Resolve (free). I wish Vegas would have such an easy to use, fast and high quality stabilizer built in.

@3POINT ... In general, I agree that Resolve stab is excellent (especially with speed) but using the same footage I've very recently used with Merc 6 OFX in VP, Merc 6 OFX provided better stability on a quite slow drive up a tree-lined boulevard (historic 35mm film video I should add). Resolve's stab unfortunately resulting in some 'bending' of the tree trunks - which was not evident with Merc 6 OFX and totally unexpected in Resolve. Quite surprising IMO given the excellent results (but not always) that I usually get from Resolve stab.

@Dexcon, does Mercalli 6 OFX show up in Resolve?

Yes, but is much slower as DR stabi, result is the same I would say at first sight..

Thanks. I've yet to see it there. I'll download and try again. I am just curious, that's all. Again, thanks!
