Newgrounds accepts video in most common formats (MP4, MOV, WMV) as well as SWF.
Looking to learn how to animate? The Animator's Survival Kit is a very popular book among animators. We also host various animation tutorials made by artists here on NG.
Size & Aspect Ratio
The standard aspect ratio for video is 16:9. We support the following resolutions:
3840 x 2160 - 4K Ultra High Definition aka 2160p
1920 x 1080 - Full HD aka 1080p
1280 x 720 - Standard HD aka 720p
640 x 380 - 360p, for lower bandwidth connections
Encoding Your Video
It is best to upload the highest quality version you can within our upload limits specified on the upload form.
If you need to compress your work, we recommend HandBrake. You can select the 1080p Fast preset, then set quality to 18 (the lower the better but 18 is considered pretty lossless) and VerySlow for encoding speed, if you have the time.
Example screenshot of HandBrake video settings.
If you are setting a bitrate for your work, we suggest 40-50 Mbps for 3840 x 2160, 10-20 Mbps for 1920 x 1080 and 5-10 Mbps for 1280 x 720. Adjust and review your results.
Sound
We recommend lossless audio (like FLAC or ALAC) but if you encode your audio, we suggest the AAC codec (default in HandBrake) and a 192 kbps bit rate for the best quality. If you upload with an AAC bitrate of 192 kbps or less it will not be re-encoded on our end for 2160p and 1080p formats. For 720p and 360p, we will re-encode the audio to 128k and 96k respectively. This is why it's best to upload the highest quality audio you can, preferably one of the lossless formats mentioned above.
