Yes, it is.
For the reasons I use it see here: viewtopic.php?f=1&t=14622&p=33062&hilit=DVDSubExtractor#p33062
The usage is actually self-explanatory for every step in the right section of the program.
In a nutshell:
1. File/Open SubtitleFile
--> choose the DVD-idx/sub that you demuxed to the hard drive (or a demuxed BD-sup - that works as well)
2. klick on the green arrow Next Step
and start the OCR. For every marked sign klick on the right character in the lower section. Pay attention to the selection regarding upper and lower case. For italics put a check mark in the box Italic
or use the spacebar.
If the characters in the upper section are displayed too illegible, try Different Palette
If you have saved a wrong character, you can undo the command with the Undo
-button. With Undo
you can even go back to the first recognized character.
If you see two or more connected characters, first try to use the Split
-button or, if that doesn't work satisfactorily, color one of the characters while holding down the mouse button and then press the Split
You can also display the recognized characters directly during or after completion of the read-out process under Review and Correct OCR Matches
in a table so that incorrectly recognized characters can be removed; after that the prog runs another pass, stops at the previously incorrectly stored character and you can correct this now.
3. If OCR is complete klick again on the green arrow Next step
, carry out the spellcheck and correct the OCR-errors with the correctly spelled word from the suggested list.
4. Hit again the Next Step
arrow and save the .srt under save as...
If you want remove HI-Items then put a check mark in the box Remove SDH subs
If the file that stores the recognized characters, the OCRMap.bin, is well trained over a long period of time, the program runs through new OCRs faster and faster and reports fewer and fewer errors.For tips, tricks and clues always pay attention to the text on the right side of the program.
