video pixelated in renderer en 3D lights

cerbero

I apply render in 3D lights for a video in .AVI format and in photoreal, the video was recorded pixelated. then I apply Render defects and the result is the same as I should do. I thank you for your prompt response.

Sorry I don't quite follow. Photo real mode is an IRay thing,so are you using IRay or 3Delight? You should provide us with some more info and maybe a screenshot of your render settings

AVI should have a compression setting, at the time when you select the output file. If it is pixelated, it could be that you have set a compression level too high, or there could just be too much "data" for your video-rendering software to process. (RAW formats can appear pixelated if there is too many key-frames and a large ammount of data to process. It can only process a few levels of detail, then it has to jump to the next key-frame, before it is done.)

AVI should not be your "Final production output". It is just a container-format. (That is my opinion.) I would use it, uncompressed, for use in another video editor, which is then used to format it to something more standard. The MP4 format container or MPG/MPEG, using the H264 codec. (Handbrake works great for that.)

If you want to avoid the horrible AVI to ANYTHING conversion... Export the frames as images. You can make the output any quality, instead of being limited to the AVI container, which uses ??? codec. (Indeo, I am sure. That is ancient. There are thousands of video codec's for AVI, all outdated, but only a few for newer container formats. Stick with H264 that almost everthing uses now.)

Just remember that Daz exports every image as a "compression frame" not a "key frame", which is not the same thing as an actual video's term or use for "key frames". A key-frame in a video is a frame that retains 100% detail, while the frames between keys, are compressed. In a video, you don't want every frame to be a "key frame". You usually have a key-frame every 1-2 seconds and 30-120 compressed frames between those. Those settings will be in any video editor, but not in Daz. It just compresses the whole thing, every frame, from start to finish. Because it thinks every frame is a "compression frame". They use that word for animation-keys, which has nothing to do with video key-frames.

Saving it uncompressed will do the opposite. Saving every frame as if it were a key-frame, which will kill any video-player. It is just too much data to process and attempt to display at 60-Hz (60-FPS). That is why they invented compression. Less data to process. Thus, your pixelization.

If it is still pixelated, when uncompressed, as images... Then you have your render settings too low. It is stopping rendering before the image is anywhere near being complete enough for a video. (Bucket-size? I forget the major 3Delight settings that control that. But IRAY uses time or resolution-detail or iterations to control the frame-render quality. Which is then compressed in the video later.)

This is where rendering as individual images will help you see which issue it may be. (Only render four or five frames as images.)

If you use the image method for your video, there are programs that will create videos from a sequence of images, such as Handbrake and CamStudio.

Mind-blowing... Here are all the actual Video-streams or "Codec" that are registered. AVI is just a container that holds the Codec format for the video. Old days of "Codec not found" are long gone. But, so are most of these AVI formats.
