White flashes/Specks-after rendering
hello again.
No returns on search.
Well, back to the cow. Cin4d R10
I have had this happen in After Effects A few times, still do not know what is causing it.I changed bit depth in AE and it seems to have solved it.
But I am also having it occur everytime I render in Cin4d.
It is ruining anything I render.It never shows up in preview, so I am guessing it is in render settings or my graphic card.I am really new to Cin4d.
In render settings,I have tried many different things, but none have worked. I am unsure of what this is. If it is graphic card or a render setting, or what..Anyone know what may be causing this, and how to eliminate it?
Would setting bit depth to higher than 8 in save of render settings affect this?Example Video To demonstrate:

Thanks for any replies…

Wierd. What render settings have you tried or are using? Vague questions result in vague answers by necessity. Do they show up when you are rendering still images on the specific frames? Are you using animation settings for the render and antialiasing (as opposed to still image)?

Lol true…
But have tried many settings.
no it does not seem to happen with still images.
settings are on animation and anti-aliasing.
The bit depth can only be changed when using a still image to render.
The only thing I have come up with is that it could be the codec.
Compression utility used is cinepak. Some of the others result in black. I must have 15 different codecs to choose…
have not tried every single one yet.
I am wondering if there is a better/other codec to use/try to see if this is the case. Also any other tweak settings I can use,since I am new to cin4d.
(right now I am in hour 7 of a render that I fear will be speckled lol–not)

Uh cinepak? Ok, don’t use that one again. That codec is circa 1991. I recommend you render out with a lossless codec so you can adjust it in a compositor (like after effect) then rerender to a more appropriate delivery codec like h264. You’ll also be able to render to multiple formats or tweak your final delivery settings without having to rerender the 3D.
If you’re on windows, download lagarith which is free and pretty good compression and performance. Other options are huffyuv and ut.
If you’re on mac, you can use the quicktime animation codec (on best settings), or prores (only visually lossless I believe). You can do the quicktime animation codec on windows too, but lagarith is a better option (much smaller).
Or on either platform you can render out to a tiff or png sequence (as separate files) or the same contained in an mov file.
All of those options will eliminate the question of the artifacts being caused by the codec.
You should also spend some time learning about video codecs. The other forums here at the cow are a good resource for that.

TYVM.
Yeah I am not very knowledgeable on codecs.I have others some work some do not.
But I started to just render out with .PNG sequence and it has cured it.
But I will look into those also.Thanks again Cory.

PNG is 24-bit lossless (or 32-bit w/ alpha). It’s a good option similar to lagarith but it’s file sizes are 20% larger. However it is one format that works on both windows and mac.
