Keep pushing and nit picking!
Ok mate you asked for it :p
From your latest tease, I personally think the added flames on Naboo (e.g… behind Qui-Gon) are moving too fast.
Those are all real fires filmed on green screen, so the physics are proper. They’re not simulated flames. So slowing it down might not look right. Itll also mess up the frame rate
Just checked out your trailer. Very nice work there. But i have to agree that the flames are moving too fast. Also the smoke is too. Using real effects doesn’t always give you the real world physics. This is true when you are using effects that are from a small fire to create an effect of a large one. You have to slow down the fire element fx footage to give the scale of a large fire.
In this shot, the smoke needs to be slowed down to around 60% of the original speed, maybe 50%. The fire, to at least 50%, but probably closer to 40-30% to give the scale required. Doing this won’t effect the frame rate of your composition. You can use after effects built in time stretch feature, with blending set to pixel motion, to apply that to the layers your fire / smoke elements are on, without effecting the compositions , or any of the other layers, framerate. I prefer to use the Twixtor Pro plugin as this gives much better results. Fire can be a pain to slow down as you can get blending effect problems. Artefacts can be painted or masked out for the most part. Which is why i prefer using something like twixtor because it gives you more control over the results. You can get great results with smoke when slowed down though. You don’t get the same sort of artefacts and the results are almost always perfect.
Now, in the following shot, the smoke is way too fast to give the appearance of the scale you need. This smoke should be slowed down to about 20-30% of the original speed. I’d say its closer to 20% but working with things like this you just can’t know for sure without actually testing out the speed on the source files. A lot of this is done by eye so it’s a lot of trial and error.
Here’s a quick test to show how slowing down the smoke and fire can give the effect of scale you need. Obviously i had to slow the whole first shot down because i don’t have the separate elements and there are a few glitches with the fire in the second one because its reacting to the background elements that wouldn’t be there when treating them separately. For both shots the smoke/ fire was slowed to 30% of the original speed using twixtor. Youtube’s compression messed up the smoothness of the result causing the smoke in the first shot to look a little jerky. it isnt like that in the file i rendered, so thats not an effect of slowing it down with the plugin.
Something i did notice, however, in the trailer i downloaded from your googledrive. The framerate is set to 24fps. It should be 23.976 when working with the blu-rays. This has caused some duplicate frames. Is your project set to 24fps or 23.976?
