"Why are my file sizes so large after rendering, and how can I reduce them?"
Uncompressed output is the default in Adobe After Effects, leading to massive file sizes, which can be avoided by selecting a compressed format.
The bitrate of your output file plays a crucial role in determining the final file size, with lower bitrates resulting in smaller files.
The duration of your video also directly affects the file size, with longer videos taking up more space.
Rendering in 4K resolution can result in enormous file sizes due to the sheer amount of data required to store high-resolution video.
Audio quality also contributes to file size, with high-quality audio sampling rates and bitrates resulting in larger files.
The codec used to compress the video can significantly impact file size, with some codecs like H.264 and H.265 offering better compression ratios than others.
Color depth, which refers to the number of bits used to represent each pixel, can also affect file size, with higher color depths resulting in larger files.
Chroma subsampling, a technique used to reduce the color data in an image, can help reduce file size by discarding less important color information.
The frame rate of your video also contributes to file size, with higher frame rates requiring more data to store.
Keyframe intervals, which determine how often the video encoder checks for changes in the video, can be adjusted to reduce file size by increasing the interval.
The quality of the render, which determines how much compression is applied to the video, can be adjusted to reduce file size at the cost of video quality.
Using a proxy file, a lower-resolution version of your video, can greatly reduce file size while still allowing for smooth editing.
Rendering in a lossless format, such as uncompressed AVI, can result in massive file sizes due to the lack of compression.
The cache and temp file folders in Adobe After Effects can quickly fill up with data during rendering, leading to large file sizes if not managed properly.
Certain video editing software, such as Avidemux, can trim video clips without recompressing them, resulting in faster processing times and smaller file sizes.
