| generate chapters from file names | If this setting is activated, each time you join several files, a chapter mark will be created at the joining points. Chapters which have been defined in the source files will be included as subchapters to those. |
| unbuffered read | Opens files using the FILE_FLAG_NO_BUFFERING flag. That means that Windows will not use its file cache. Since AVI-Mux GUI reads sequentially forward, there is no use in the file cache of windows, making this read mode faster. Note: This setting was subject to a couple of problems and bugs, but those should no longer occur. |
| read ahead asynchronously | AVI-Mux GUI operates on pieces of 512 kB. Unless caching itself is disabled, AVI-Mux GUI will access files only in such pieces. When this setting is enabled, accessing one such piece of a file will immediately initiate reading the next piece, so that, when it is required, it is already loaded, or at least, loading is already in progress, so that it takes less time. This setting was implicitely activated if and only if "unbuffered read" was activated in versions prior to 1.17.4. This setting should be disabled if and only if it leads to problems, as it makes AVI-Mux GUI slower. |
| maximum chunk size in kByte | Any chunks which exceed the indicated size will be considered broken if this option is activated |
| try to retrieve correct chunk size | If this option is activated, AVI-Mux GUI will look into the chunk header of any chunk that exceeds the maximum indicated size and check if the size indicated there is "better". If it is not, the chunk will be ignored. If this option is deactivated, every chunk which exceeds the indicated size according to the AVI file index is ignored without further verification. |
| force MP3 streams to VBR | Every MP3 stream will be treated as VBR, regardless whether or not it is indeed VBR. Recommended: deactivated |
| change dwFourCC "DX50" to "divx" | DivX 4 and divX 5 - Codecs use divx as identification code. Unfortunately, there is at least one tool out there which creates AVI files containing a wrong DX50 code to refer to divX 5. If this option is activated, this wrong code will be fixed when remuxing the file. Recommended: activated |
| activate CRC check as default | Indicates whether or not
CRC check will be activated automatically when a
Mode 2 Form 2 - source file is loaded. This prevents that corrupt data is muxed without the user noticing this. Recommended: activated |
| Ask whether or not to check for CBR | When an MP3 file is loaded, AVI-Mux GUI will look at the first 1000 frames. If they suggest the file to be CBR, the user will be asked whether or not the entire file is to be checked for CBR. If the user denies, the file will be treated as VBR. Note that the entire file needs to be read and checked, which might take some time. |
| always check for CBR | AVI-Mux GUI will scan MP3 files until either the end of the file is reached, or until it is clear that the file cannot be CBR. |
| never check for CBR | Every MP3 file is treated as VBR. This will increase overhead for AVI files when using MP3 CBR sources |
| display verification result | Inidcates whether or not the result of the verification of an MP3 file which looks like CBR is displayed as a dialogue window. |
| Import chapters | Select whether or not chapters from input matroska files are imported as well, or if they are ignored |
