My first animation project - some advice please
show user profile  mike_renouf
Hi all,

I have my first animated walkthrough project impending. I have read from previous posts here that Quicktime pro is a good codec to use. Is that still the case? I'm ready to stump up some cash - up to about £100 if necessary - to enable me to render out from Vray to whatever format is best.

Currently I'm trying out the process of pre-rendering light cache and irradiance map so I can get familiar with that. Then I'll get to grips with compiling all the still frames.

Any ideas or suggestions would be gratefully received.

Render to a imagesequence, a tga, png or even tiff.

About the GI:
Lc to flytrough, render it only once
Switch lc to from file, now render the irr map, incremental add.
Depending on the intensity of the camera movement render a irr map per 25/50 frames.
Now disable lc alltogether because the info of lc is stored in the irr map you just made.
Set the irr to from file and render the whole sequence.
Ive had the best results(read least flickering) when rendering the irr on one machine.
Good luck :)

I always render to a png sequence just to keep size under control on my hard drive, easier to backup.

Than out of a compositing program I seem to really favor *.mov h264, however since most people upload stuff to youtube its super forgiving on format, you could almost use whatever and it will read it, so it depends on your use.

I would never render straight to a movie format from Maya thou, there's many times it really saved my butt to just replace a few bad frames, quick clone stamp fixes, roto out sections of some frames using other frames, ect ect ect.

i have a quick way of rendering animation with vray. Follow these steps let me know if you get stuck. This allows you to do the lc/ir process in 2 steps:

Just be aware, anything animated must be hidden for this and rendered on a seperate pass. Either render the animated objects with bruteforce/light cache... OR

FYI (not required but handy to know). Another way to render your animated objects (again render them separately so the shadows dont mess up with the ir/lc) - is keep the irradiance map/light cache on in the render settings, & in the material for the animated object - select Options > Use Irradiance Map (uncheck). This will force that particular material to be rendered with brute force regardless. This can be a little bit more labour intensive which is why I suggest rendering it as a brute force/light cache - you could use VMC to speed up the process and select all your animated objects and apply this automatically to them, up to you.



Essentially Step 1 lets you do the IR and LC in 1 frame and removes the need to render the LC & THEN the IR with every Nth frame blah blah.

If you want to see this in a bigger format I just made a copy of this and blogged it for future use and formatted it a bit for easy reading

Brilliant - thanks everyone. I'll do some tests and report back. I was very aware of the need to render individual frames as an image sequence, and had it in mind to use uncompressed png.

I wasn't sure what codec to compress with though. I'll try .mov h264 as 3Ddeath suggested.

Cheers guys.

Wow nice explanation Donvella :)
With images and all :)

@Mike,

Since you are using h264 in a mov container, its also worth considering using mp4 as container of your h264 footage because not all devices play .mov(since you need to have quicktime installed) but all play mp4. The content is the same though. Atleast, thats the feedback we get from clients when we send a .mov :)
