Video Format: Export Settings
- Format: MPEG4 (i.e., with an .mp4 extension) are preferred, though common formats like AVI, MPEG2, WMV and DivX may also be accepted (I usually upload H.264 video in an .mp4 container).
- Encoding method: Constant bitrate (CBR) is preferred.
- Bitrate: This is a big restriction, especially for free users. The maximum rate bit rate accepted for videos uploaded by free users is 600 kbps (I normally upload HD video at around 5000 kbps and standard definition video at 1,000 to 2,000 kbps, so this restriction came as a bit of a shock). The 600 kbps limit refers to the total bitrate (audio and video). Therefore, if you want relatively good sound quality (e.g., mp3 at 192 kbps), you are looking at encoding your video with a bit rate of 400 kbps. Premium members can upload file with any bitrate as long as the total file size is less than 1 MB
- Total file size: Free users have a limit of 40MB while premium users can upload files that are up to 100 MB
- Resolution (frame width and height): Free users cannot upload with a resolution greater than 800Ã600 while premium users can upload any resolution, including HD (but bear in mind, if you have a 100 MB limit, high quality HD videoâs canât be more than a couple of minutes long). The normal resolution of the Nico Nico Douga video player is: 512 x 384 (4:3 mode), 640 x 384 and 640 x 360 (Widescreen 16:9 mode). As a free user, I just export my video at one of those settings (unlike in YouTube, it is normal for there to be a black bar on all four sides of an uploaded widescreen video).
- Pixel Aspect Ratio: I would recommend square pixels (1:1).
- TV Standard and Frame Rate: As Nico Nico Douga is a strictly Japanese site, it is probably best to use the countryâs TV standard (NTSC) and itâs corresponding frame rate (29.97 fps).
My export settings (for free user) are shown. My videos posted on the site are music videos, so I keep a fairly high audio bit rate. If audio quality is not that important, you can decrease that and increase the video bit rate slightly. The settings for frame width and height are for widescreen (16:9) video. If I were uploading video with a standard 4:3 aspect ratio, I would probably go for 640 x 480 or 512 x 384.
