Issues with camera pan during rendering

[stevenjamestaylor]

Morning: I have encountered an issue when rendering a camera pan at 24 fps- the move is 200 frames long and is a very short distance-

while I get smooth playblasts of the animation after rendering there is a stutter in the motion, like the camera is on stepped keys. it is a simple push in nothing complicated about the move

I am running maya 2017 update4

i7 3.5GHz

Hi @stevenjamestaylor

Thanks for posting! I see what you mean by the camera looking like it is stepped. Any chance you could post your scene so I could take a look at it? 🙂

If you create a new camera (create > camera) and render that one, does the stepped effect still happen?

I'd also recommend Resetting your Preferences if you have not had the chance to do so 🙂 Always a good place to start when Maya starts misbehaving.

Let me know if the problem persists! I'd be happy to continue assisting you until we figure it out.

Hi Jordan- thanks for checking into this with me-

I will try a render with new cam and gosh I think I reset my preferences every other day at this point 

Attached is the scene- i didn't include the alembic caches of my Mash nodes but i has the camera move and major animation in it.

Thanks for helping out- I was really bummed to get that result back from the farm and stylistically I would like to be able to use shots like these

on scale- apologies for the oddity of the scale and placement of objects- working from a complicated device that has scales from feet to nano-meters- yep it's a biomedical animation- so in order to link my shots up, I had to go off center a bit

Hi again @stevenjamestaylor

Thanks for sending that over 🙂 I tested with some playblasts (rendered normally) and looked into the camera settings, but didn't see anything that would justify a weird stepped effect. What renderer are you using on your farm? I'd check to make sure that you have the most up-to-date version of the renderer, and that your graphics card drivers are all up to date as well.

Let me know how rendering with that new camera goes! I'm very curious as to why this is happening.

Cool animation though!! Very cool project 🙂

@stevenjamestaylor

Forgot to mention that we have a new update available for 2017 as well! 🙂 Update 5! It should be available from your Autodesk Account or Desktop App. Let me know if you are unable to get that download and I will get someone to look into your account.

hi -thanks for the reply- 

I get the same result smooth playblasts - stepped final renders

I do have updated drivers and the like- and I am using ZYNC to render with ARNOLD 5.0.1 - I cannot update Arnold to the latest version it is not supported by the cloud render- which works like a charm btw.

this effect did not manifest when the animation was 2x as long only in shorter duration's and in small/slight camera moves

I will try pushing new renders with a new camera up tonight to see if it helps- optimize scene all that stuff to tighten up the loose ends

love to get this one figured out- 

I am also gonna try at 30fps- 

regardless I would like to know why this is happening and not be subject to it, but learn to work around or compensate- so thanks for sticking with me to a resolution

Hi!

I rendered the sequence (camera THECAM frame 1-50) with half resolution and reduced sampling/day depth. No problem with Maya 2017 (Arnold 5.0.0.2) and Maya 2018.

Please test this too and just use Render Sequence with" add to Render View" enabled (only takes some minutes). Does this work?

[stevenjamestaylor]

@mspeer@jordan.giboneyso I have run both solutions suggested-

mspeer- I did not get a similar result- the camera is still choppy- especially noticeable when the lights go out - I would need to keep my render quality high regardless- thanks for taking a look

Jordan- all experiments produced same result- camera is still choppy- 24fps-new cam (freshly optimized scene) 30fps-same result

[stevenjamestaylor]

@jordan.giboney - I am going to try Update 5

Hi @stevenjamestaylor

Just wanted to check in and see how things were going 🙂 Did Update 5 rectify the camera issue?

Keep us posted! We are happy to help!

[stevenjamestaylor]

@jordan.giboney -- I have been able to clear the issue up- by @mspeer 's idea of rendering locally- I have also deleted and rebuilt the camera, which seemed to also remove the stutter on the render farm-

I can't understand why this happened and therefore it's still an open mystery to me 

thanks for the ideas, suggestions and taking a look at my file 

Also Stephen Blair, on the ArnoldAnswers forum jumped in too

people's THANK YOU!!
