AccuSplit 3.7.1 - User Guide and FAQ

1. Launch TMPGEnc and from the FILE drop-down menu select "MPEG TOOLS..."
2. Select the "SIMPLE DEMULTIPLEX" tab and enter the name of your video in the "INPUT" field or browse to your video using the BROWSE button adjacent to the "INPUT" field.
3. Accept any default entries that are placed in the "VIDEO OUTPUT" and "AUDIO OUTPUT" sections.
   
4. Click the RUN button and wait until TMPGEnc finishes demultiplexing the video and audio streams from your original video file.
   
5. Annotate the name of the video stream and audio stream files that TMPGEnc just created, they are listed in the "VIDEO OUTPUT" and "AUDIO OUTPUT" fields. You will need to reference these files in the next step.
   
6. Select the "SIMPLE MULTIPLEX" tab and browse to the video stream file annotated in step#5 using the BROWSE button adjacent to the "VIDEO INPUT" field.
   
7. The "AUDIO INPUT" field should be filled in automatically if it is not, then browse to the audio stream file annotated in step#5 using the BROWSE button adjacent to the "AUDIO INPUT" field.
   
8. In the "TYPE" drop-down list select the type of MPEG file that you are trying to recreate. This should be either: "MPEG-1 System (automatic)" for a generic MPEG-1 file, "MPEG-1 System (VBR)" for a Variable Bit Rate files, or "MPEG-1 Video-CD" for a Video-CD format file.
   
9. In the "OUTPUT" field select the desired name for your re-encoded MPEG file.
   
10. Click the RUN button and wait until TMPGEnc finishes multiplexing the video and audio streams into a re-encoded version of your original file.

Frequently Asked Questions - AccuSplit

1. I used AccuSplit to split a large video file into pieces for storage onto CD-R. When I try to play back the video files stored on the individual CDs some of the file segments refuse to play in the media player. Why do some of the segment files play and others fail?
   First make sure that you are using the latest release of AccuSplit. Registered Full Version users of the software are entitled to free upgrades to new releases and users of the free Shareware Version can also download new Shareware releases from this website.
   
   Early releases of AccuSplit (prior to v3.0) were sometimes able to split large MPEG files into smaller segments that would then be independently playable, however this was not a designed-in capability of those early versions of the software and it was not 100% reliable. However, beginning with the v3.0 release of the software, AccuSplit introduced the capability to split AVI, DIVX, and MPEG-1 format files (including Video-CD) into "independently playable" segments.
   
   You can access this feature by selecting the Video File Smart Split option. For complete details on the various codecs and formats supported by the latest release of AccuSplit please see Question #12. Some video types like WMV are not yet supported via Video File Smart Split and these file types can currently only be split using AccuSplit's standard file splitting mode which turns them into AccuSplit segment files (*.SEG). These files will not be independently playable and the file segments must be recombined (using AccuSplit) into a copy of the original file in order to play back properly.
   
   
2. A database file that we have has grown too large to be read by an application that we are using. Can I use AccuSplit to split the database file into smaller pieces that our database application could then read?
   AccuSplit will have no problem splitting your large database file into smaller segments. AccuSplit will also have no problem taking those segments and using them to reconstruct an exact replica of your original database file. However, the individual AccuSplit segment files will probably not be readable by your database application.
   
   There are at least two potential problems with your plan. The first is presuming that the database will still be operational after slicing it into arbitrarily sized pieces and the second is that during a Standard Mode File Split operation AccuSplit adds a 1KB data header to each of the segment files. This header includes information such as the original composite file size, the number of file segments created during the split, the MD5 message digest for the original composite file, and the MD5 message digest for the current segment file. AccuSplit uses the information in this header to insure that the data integrity of the file is maintained during the reconstruction process. It is very likely that this data header will be interpreted as a form of data corruption by the database application.
   
   However, to meet the needs of users who may desire to split a file into segments that do not include any extra information (ie. the 1KB AccuSplit data header) AccuSplit includes the ability to perform a Raw Mode Split operation. During a "Raw Mode" split AccuSplit will not add the 1KB data header to its file segments. These segment files will therefore only contain the raw data from the original composite file.
   
   
3. I have just purchased the Full Version of AccuSplit. It looks like the next release of the software will have some new features that I really would like to have. When this new version is released will I be entitled to a free upgrade?
   Absolutely! Any user who has purchased the Full Version of any prior release the software will be eligible for a free upgrade. Simply send an email to: listing the name and address that you used when you purchased the software. After we validate that information against the registered list of users in our database we will email you a copy of the latest Full Version release of the software.
   
   
4. I am interested in purchasing the Full Version of AccuSplit so that I can split large movie files into CD-sized pieces that can be sent to my relatives. Can my relatives use the Shareware Version of the software to rebuild these file segments into a copy of the original file, or must they also purchase the Full Version?
   The answer to your question is no, your relatives do not need to purchase the Full Version. The Shareware Version of the program only restricts user capabilities during the file split process. The file rebuild process is not restricted in any way. Therefore, the Shareware Version of the program can be used to rebuild any file segments that you create with the Full Version into a copy of the original file.
   
   
5. I split an MPEG-1 file using AccuSplit's "Video File Smart Split" option. No errors were generated during the split process but some of the segments don't play. What am I doing wrong?
   You occasionally see this problem when trying to split MPEG-1 files that weren't encoded in compliance with the MPEG-1 specifications. The fix in this case is to re-encode the file so that it complies with the MPEG-1 specs. Fortunately there is a relatively easy way to do this that doesn't involve a time consuming re-rendering of the entire file.
   
   
6. Why do I get a message notifying me of missing DLL files INETWH32.DLL and ROBOEX32.DLL whenever I open the AccuSplit help file?
   You are using an old version of AccuSplit. Please upgrade to the current release of the software which includes an updated help file that corrects this problem. Registered Full Version users of AccuSplit are entitled to free upgrades to new releases (see Question #4) and users of the free Shareware Version can also download new Shareware releases from this website.
   
   
7. Do I really need to have DirectX installed to use AccuSplit?
   AccuSplit only requires DirectX when you try to split an AVI format video file using the "Video File Smart Split" option. This is the option that enables you to split the AVI file into independently playable segments. So unless you are planning to split AVI files using this advanced option you do not need to have DirectX installed.
   
   
8. I tried to use the "Video File Smart Split" option to split an AVI file with a FOURCC code of "MP43" but I keep getting the error: "ERROR Code 1421? Cannot find compressor for smart recompression type". I can play the file without any problems. Why can't I split it using the "Video File Smart Split" option?
   The "MP43" FourCC code identifies AVI files encoded with Microsoft's MPEG-4 version 3 codec. Unfortunately, only initial beta releases of this codec allowed for file encoding or re-encoding. All current versions of this codec (which is distributed by Microsoft) support only file decoding which allows for playback only. Since AccuSplit needs to access a codec's re-encoding capabilities whenever it attempts to split a file using the "Video File Smart Split" option and because it is unable to do this for "MP43" type files you end up getting the "ERROR Code 1421" message. AccuSplit will only be able to split "MP43" type files using the Standard Split mode which means that the file segments will not be "independently playable".
