Nintendo Video Convertor 3DS is a very useful homebrew application has been developed which enables users to play videos on their 3DS device. This application has the added advantage of supporting HoriHD and Stereoscopic 3D videos. Previously, users had to convert videos through the command line using ffmpeg. However, a GUI program has now been created that simplifies the process by allowing users to import their videos and select various options such as output format and filters.

The converted video can then be saved to an SD card and played on the 3DS. Additionally, the developer has extended the application's functionality to support WiiMC, which was also previously cumbersome to convert manually.

Usage

• Extract the zip. If you downloaded the ffmpeg-less version, download ffmpeg and put it to the same directory as nvc.exe
• run nvc.exe
• click the 3 dots and select your input video
• Choose 3DS/Wii

For 3DS:

1. Choose if you want to output standard 400x240p video (choose for Old 2DS), HoriHD 800x240p video, or Stereoscopic 3D video
   1. if you choosed 3D video in step 4, select if you input video has the 3D encoded as left/right or up/down
2. select the codec to use. For Old 3DS, select mpeg2 or mjpeg, for new 3ds you can use H264
3. select the downscaling filter. Lanconz smartly mixes the pixels together, nearest neighbor just copies 1 pixel, and mix downscales it with lanconz to double of the resolution, and then uses neighbor to downscale it to the final resolution (its sharper than pure lanconz, and its not as jagged as pure neighbor)
4. select if you want to stretch the video vertically or not. "no stretch" is no stretching, 10% scales it vertically on the vertical axis, and Full stretch stretches it to fullscreen
   1. you may get popup during conversion that the vertical resolution is higher than 240p. If you dont want to stretch the video vertically to be 240p, click "no" and it will scale down the X axis so the aspect ratio stays same
5. click convert
6. copy the outputted file to your SD card, and then play it with Video Player for 3DS
