difficult to decipher. (See StreamTools File Info portion of this manual for details) As an aid, the

encoder automatically places a Log file that contains all information used to create the encoded file in the

same

directory as the encode for future reference. A DTSPBR file can also be created in the

same fashion by checking the Auto PBR option from the Options menu.

The log file contains all information that the Encoder used to create the resulting encode plus any other

notable information that arose during the encode process. When an Encode is created, a log file is placed

in the same

directory as the encoded file. The log file will share the same name as the encoded

file with the extension (_log.txt).

Warning: Log files are not protected and can be edited. Thus, information

contained within the LOG FILES SHOULD BE BACKED UP!

7.6.1 Encode Settings

The Encoder Settings portion of the log file contains all of the information the Encoder used to create the

resulting Encode. This includes the full path of the input material and output destination. The

destination type, stream type, sample rate, bit width, constant bit rate, dialog normalization, timecode

parameters, button options, downmix coefficients, and program information. This is a quick way to

determine what settings were used to create the encoded file. The Encode Settings is located at the

beginning of the log file and will makeup most all of the information provided in most log files.

7.6.2 Encode Results

The Encode Results portion begins at the bottom of the log file directly below the downmix information

section. It contains information about events that occurred in the encoder once the encoded file began

processing. There are three type of information that can display here; MD5 Verification, PBR

information, and Saturations Warnings. (See the three sections below for details)

7.6.3 MD5 Validation

MD5 data verification code: This letter/number code allows a user to late validate that the encoded file is

identical to the original encoded file. Data can be lost during file transfers, thus an MD5 check should be

run on any encoded file that has been transferred and the new MD5 letter/number code should be cross

referenced with the original letter/number code to ensure they match. If the codes do not match the

transferred encode should be considered corrupt and the transfer should be done again. (some chip sets

in external hard-drives will cause corrupt data transfer) The MD5 data verification check should be

performed if an encoded file has been transferred from the original encode location.

7.6.4 PBR Data in Log Files

When the option is checked and a Master Audio stream is encoded, a Peak Bit

Rate analysis is performed on the encoded file and a ‘.dtspbr’ file is created in the destination directory.
