This new tool allows you to recompress your MP3 files to save additional space. It can process MP3 files encoded with VBR and CBR bitrates. In both cases, you can save a couble of bytes or kilobytes, depending on the file.
MP3Packer maintains the original file tags, meaning there is no metadata loss.
MP3Packer tries to recompress the file losslessly, meaning the audio should not be changed. However, it is recommended to test the audio streams with Audio MD5 Checker to make sure they are identical.
This new version moves the HME options to a new Advanced Options window and adds a new setting for specifying the GOP type:
By default, the GOP Type will be Closed which allows seeking in the video. SVT-AV1 uses the Open type by default and the resulting videos in the previous SVT-AV1 GUI versions would have problems seeking. This is now solved by this new option.
Additionally, this version have the following improvements:
The First pass encoding will be skipped if the software was interrupted while performing the second pass encode.
A bug in the second pass where the additional arguments were not passed correctly has been fixed.
You can download this new version on GitHub by clicking here. The new version comes bundled with the newest SVT-AV1 release, which I’ve built yesterday using the media-autobuild_suite.
This release adds an option to prevent the use of Pipes which should make encoding stable. The downside of this is that the software will need to create a temporary .y4m file which may be huge depending on the video to be converted.
