Hoping people can offer some advice on this. I'm increasingly asked for flythroughs along side the still work. I have done this in the past saving out 8bit tiff sequences and putting them together with a bit of colour correction in AE - just getting a monthly subscription when I need it.
I was wondering if this was the best way for simple flythroughs? Even just flat 8bit images at 25 fps mount up to a considerable size so im not sure how people stretch to 16 or 32bit multilayered files. Must be a nightmare? Also can anyone recommend a simple but powerful editor that can add good quality text and also encode a high quality output? Whilst I can use AE I feel it can be a bit overkill but I like the colour controls.
Do people set number of passes or noise amount as there time control per frame? I also prefer the fixed noise which I know is perhaps not what most people chose. I find it less distracting over that dancing noise on under sampled frames. I was thinking maybe a denoise of 0.5 on a 1080p frame might be about right. Does anyone have any experience of testing the various levels and finding a sweet spot here? In the end does final compression make the denoising worse as you are losing even more detail or is it in a way better as it saves time and that extra detail we might get through less denoising and longer frame time is washed away with compression of the final clip anyway?
Thanks for any help on this, Cheers.

Not sure about the animation software workflow, but as to noise level, here are some numbers we have established mostly based on user feedback:
Quick preview - 10%
Final with denoising - 5%
Final with no denoising - 2-3%
The sweet spot for denoising amount seems to be something between 0,5 and 0,7 - it gets rid of most of the noise, while steel preserving fine detail.

Thanks Maru, they sound like sensible figures.

Final with denoising - 5%
I've found that since the recent update to the noise quality, that 7% might be the new 5%.

Im using the latest C4D beta which has also just got the same core speed boost, and yes the quality is very good. What Im noticing though is the noise measuring tool is getting fooled on some frames - like dropping from 25mins on one frame down to 15 the next and then back up to 25. So the odd frame is more noisy than the rest of the set. Dont know if its a C4D thing or a general core bug.
Im finding on this particular scene that im probably needing better AA over GI but I'll need to go away and remember which was to adjust the multiplier for that - is it greater or less than the default 16 for quicker/better AA and slower GI? Also will I then need to adjust my noise limit accordingly if its just measuring GI rather than AA - maybe I'll try 7%. Anecdotally Ive noticed maybe edges an building outlines have taken longer to clear compared to the noise recently. I dont know if corona is putting more juice in to clearing noise by default or if its just that everything is clearing so quickly the AA is more noticable at the lower passes.

For commercial animation, i'm actually setting up my standard @3% noise with 0.4 denoise for 1080p. I like it clean.
