Frequently
Asked Questions
What is
the difference between the Light Edition and the Full Edition of
FairUse Wizard ?
Light Edition has the folowing
limitations :
- no iPod Video encoding
- encoding target file size limited to 700 MB
- no range selection
- no quality based encoding
Furthermore, the full edition is optimised to fully exploit Dual-Core,
SMP, and Hyper-Threading CPU architectures, resulting in much faster(1) encoding and has
an auto-update feature not available in the light edition.
Is
FairUse compatible with Windows Vista ?
FairUse
is compatible with Windows Vista. If you have trouble running FU under
Vista, right-click on the FairUse Wizard shortcut and check the "Run in
administrator mode" box.
Is
FairUse compatible with Linux ?
FairUse works just fine with Wine. If the DVD drive
is not detected,
you may have to enable the ide-scsi mode for the DVD drive.
FairUse
comes up with a psikey.dll missing error whenever I run it.
Furthermore, I can't use the DivX encoding, only XviD is available.
The psykey.dll error comes from the DivX codec itself when FairUse
tries to load it. This happens because you installed the ad-sponsored
version of the codec, then used some spyware removal tool like Ad-Aware
that removed the "ad-support" software.
To take care of this isue, you can choose to uninstall the DivX codec,
or install a fully functional version of it. With a "hacked" version of
the codec you won't be able to encode with DivX since the codec won't
load.
What settings should I use
to get movies that will be compatible with my standalone DivX player ?
Default settings do guarantee compatibility with all standalone DivX
players. If you run into problems, restore the defaults settings using
the dedicated button. Please
note that only DivX and XviD video codecs, MP3 and AC3 audio codecs,
and AVI file container will work on standalone players.
How can I convert the VOB files I already
have on my hard
drive ?
Well, you can't. FairUse was designed to make backups of DVD you
already own, so you should make your backup from the original DVD.
Nevertheless, you could eventually build an ISO image with a DVD
burning software like Nero and open the ISO file from within FairUse.
What is the best codec between XviD and DivX
?
The
XviD codec is embedded in FairUse, while DivX is optionnal and has
to be installed separatly. Some people only swear by XviD, while some
others only want DivX. Your best bet is probably to try both and make
your own opinion.
I have tried to do a DVD backup with DivX
but FairUse produces
noticeable undersized files, no matter what target size I set.
Some
movies are actually very compressible, so even with the best quality
the codec won't need the whole target size. This can for example happen
on movies like "From Hell" or "Avalon" that
have lots of dark scenes, because dark pictures can be compressed a lot
by the codecs. "From Hell" will usually not even fill a single CD with
a 128 kb/s audio track. It is known as "codec saturation". This issue
is DivX-specific and should never happen with the embedded XviD codec.
In quality encoding mode the final size is unpredictable and always
brings the best possible quality for the selected resolution.
FairUse
creates oversized movies
Please make sure you're encoding in 2-pass mode. In quality
encoding mode the final size is unpredictable and always
brings the best possible quality for the selected resolution.
I
would like to have subtitles as a
separate file rather than embbeded in the video ?
Check
the "extract subtitles" box and select the desired subtitles track to
get an IDX file and a SUB file. The files have the VobSub format, and
can be read as is on most standalone players.
You can also use VSRip or SubRip to extract and/or
convert the subtitles from the IFO and VOB files
extracted in the
project folder if "extract subtitles" is checked.
What target resolution should I set to get
the best results ?
In
the case of an action movie, you should'n go too high, while for a
drama or a dark-pictured movie (The Others, From Hell) you can use
higher compression ratios.
If
the compression ratio is too low, this means that the target size is
too big, but actually this is not a problem because you won't loose
quality. In the worst case, you're wasting some space. On the
other hand, if compression ratio is too high, chances are the picture
will exhibit artifacts.
If in doubt,
leave the default settings
suggested by FairUse, it will be fine in most cases.
Should I enable Lanczos
resize ?
Lanczos resize results in
a sharper picture, at the cost of less compressibility.
If in doubt, leave the
default settings
suggested by FairUse, it will be fine in most cases.
In quality mode the Lanczos resize defaults to be enabled.
Should I check "BOB deinterlace" ? If so,
what does it do ?
BOB deinterlace attenuates the artifacts on some poorly encoded DVDs.
Your best bet to know when to enable it is to trust FairUse's
auto-detect feature.
What is the FairUse Wizard
distribution licence ?
FairUse Wizard is
distributed under GPL. The source code is available from here.
Should
I check "TV
mode" ?
The TV mode should be checked if your main display target is a regular
4/3 TV. With
this option disabled, the aspect ratio will be slightly wrong on a 4/3
TV.
With this option enabled, the aspect ratio will be slightly wrong on a
computer screen. You may eventually test both on a short clip or a
trailer.
What is the "Credits start" button ?
This buttons allows you to tell FairUse where the end credits start, to
encode them with a lower quality. Thus, more space is allocated to the
main movie. Please note that this feature only effects XviD encodings.
What are the software license terms ?
Please see the license terms
page.
What is
your privacy policy ?
Please see the privacy policy
page.
(1) The performance gain may vary
depending on the hardware architecture and the codec used for the
encoding.
