Adobe Premiere Video Exports
When exporting projects from Adobe Premiere I found that my final video files were not displaying the same way as the rendered version in the project file, specifically segments that contained a great deal of motion.
To maximize export quality, there are a few settings to keep in mind. The image at the bottom of this post is a screen capture of the Premiere export menu.
The purple box contains the export format. As H.264 is currently the industry standard, H.264 should always be used unless the project requires a specific format.
The yellow box contains the video tab where specific video encoding can be edited. The red box denotes the Bitrate Settings. Bitrate refers to number of bits processed per second. In order to pick the necessary Bitrate Encoding option, you need to consider filesize limitations and the amount of motion the video depicts. Filesize can be understood by the following equation: filesize = bitrate x time. As such, the higher you set the bitrate, the larger your video file will be. Greater motion or differences between frames will require a higher bitrate in order to properly display all of the “data” in the video.
The Bitrate Encoding options available are CBR (constant bitrate), VBR (variable bitrate) 1 pass, and VBR 2 pass. Exporting with CBR allows you to set a Target Bitrate to be maintained for the entire video. CBR at a high bitrate will produce a high quality video, however the filesize will be quite large. Exporting using VBR allows you to set a Target Bitrate and Maximum Bitrate; the encoder will provide the target bitrate for most of the video, however the bitrate fluctuates up to the Maximum Bitrate depending on the needs of the video. The difference between 1 pass and 2 pass is that 2 pass analyzes the video before encoding to provide maximum video quality and minimal filesize.
So if you have a “motion heavy” video that does not display properly when exported, increasing the Target Bitrate will help increase the quality. While VBR 2 pass provides maximum quality and minimal filesize, it will take much longer to export and is not always necessary.
The final blue box contains the “Use Frame Blending” option. This box should be checked off if your “motion heavy” video is not exporting properly. This option allows motion to appear smoother, but use this option sparingly as parts of the exported video may appear blurry as a result.
