Nice!

A tip, if you render 24/30 fps you basically need some motion blur for a smooth movement. TV/Cinema works with few frames per second because cameras automatically get motion blur because of shutter speeds. Without it you would need much more frames per second to get a smooth appearance.

With 3D it renders ultra sharp stills so if you use 24/30 frames a second it’s not really smooth for your eyes. If you render 24 fps and put the motion blur at 1/48 you get a more natural looking/feeling result.

Of course that will also blur the object a bit but it would be the same as a jewellery commercial for TV.

Thanks for pointing out your experience

I did a quick render just to show the difference.

This is 24 fps without motion blur:

This is also 24 fps but with 1/48 motion blur:

Motion blur increases render times and rendering more fps of course also adds render time. So sometime you can cheat to use software like Topaz Video AI to actually change the framerate of a existing clip. What Topaz Video AI will do is to create frames in between the other frames and that works quite well and is way faster than rendering.

So this is basically the first clip without motion blur but changed to 50fps.

And I always render stills and render them as video using DaVinci Resolve. Real easy and if you use images to start from (like EXR or even 32-bit tif) you have more control of the result since you also can decide what codec you want to use and quality the video will have in the end.

Just some side info :slight_smile:

Hi Oscar,

Thanks for your sharing on this thread. Will Gibbons recently turn me on to DaVinci Resolve, and it’s been so much quicker for me to adopt. One of the things I like most is rendering out animations across a few different machines and then compositing the sequences in DaVinci. Still, as a newbie, if you’d care to share, it’d be nice to hear about your workflow and/or if you could share links to others who might have nice DaVinci frame to animation sequence workflows.

Cheers!

I’ve very little experience with DaVinci as well let alone a certain workflow :slight_smile: But I did like DaVinci a lot from first sight. Think it makes sense how it’s organised from cut up to deliver with the buttons at the bottom.

What can be interesting to look at is how you can add motion blur inside DaVinci. Basically there are two ways, one pretty simple one using the color grading tab in DaVinci. That one is fast but less perfect. And you can do it based on Motion Vectors which will actually analyse your footage in a more thorough way and calculates how the camera was moving and will base the blur on that.

Last one is way slower of course but they are also nice tricks if you have frames without blur and there appears a bit of stutter. It always depends a bit on your footage but often such cheats works really well.

And if I need to render a rotating ring on 360 degrees I know 6x24 frames will make it turn 2.5 degree every frame which will not look smooth on the outside where the motion is fastest.

Not much a problem if you’ve fast hardware but I wasted also a lot of time by doing just too much motion in too little frames. And you can better render some frames to many than too little so you have to do all again. But Topaz Video AI and DaVinci can really help,

If you like to try Topaz Video AI, that also supports image sequences but want them to be 16-bit tiffs.
