hay jelly pal..
Well, right now, I did not give up on ffvfw, but is on hold w/ me too.
I'd like to create an interface that is specific to it so that some of the more
common settings could be quickly changed w/in an instant - if possible.
But, for now, i'm researching other avenues.
I'm currently working w/ mencoder, but I'm having some reservations with
it.
The reasons are:
* Uneasyness of bitrate settings. ie, in TMPG, you can easily change the
....bitrate, and notice the filesize (or quality) change, but in mencoder, you
....have to really pull your dingaling something hard, to notice anything. In
....other words, you almost can't change em. I think that we can all agree
....to an extent, that bitrate settings or not easy to do w/out first changing
....other params that (indirectly) alter either the source during the encoding
....phase, or bitrate, or whatever
* Too many errors during the encoding. mencoder is VERY fussy. The slightest
....wink, and it's dumping your screen full of errors, which by the way, add
....to your encoding "times". See below
Fig A. below for an example
....of some errors you get. It's very frustrating to work w/ mencoder. At
....least on my end. I'm working mencoder under w98gold. Others may be
....having better results (or less errors) using other OS. It would be interesting
....to note that OS's that are producing either: less issues; better quality; or
....whatever, when using mencoder in a given OS. Perhaps it's OS tuned
What someone needs to do is research exactly
which settings that
effects these various types of errors, and note them w/ further study, to
find the anti-dote to encode w/out resulting w/ errors. Hope that made some
sense

Now, if it worrent for my GUI in the works, I'd 'ov given up on mencoder and
found something challenging in other avenues, but the design helps me to
continue tinking w/ mencoder
If I'm not mistaken, I think you can also use MPLAYER filters too, inside of
mencoder's encoding params. I haven't really tried any of mplayers'
command-line params just yet, (because of the other mencoder issues to
be worked out) but my huntch is set.. that some of the params can be used
w/in mencoder.
One of the things I noticed about mencoder, is the Matrix. Some of them
can produce smaller filesize. So, its more of a challenge to find a "sweet"
spot for this - perhaps a new endeavor for kvcd, if he thinks it has an new
avenue of research
But, in my OP, I think that we really need to
NAIL down the bitrate
mechanism. We need to know explicitly,
WHAT setting(s) are there
that are respobile for chaing (ie, raising/lowering) the bitrate. For example,
if I change my (min=600 and max=1800) to a (min=900 and max=4000)
I wanna know for sure, that either my filesize will change, or my quality will
change
.
.
this seems to be a topic of interest here
Lots more to say, but I'm debuggin my GUI. I have other ideas for it, but
I would really like to know if mencoder is rally worth GUI'ing it, or just scrapping
it for something new. Hay, Jorel, do you stuff, search out the internet for
a new toy (command-line) encoder for all to play with. He does a great job
at finding these things
Also, w/ Muaddib back in town, he can update is MStacker app to now (as an
option) produce mencoder scripts
etc etc. So now we have a few
GUI's and MStacker to mess around with
and
CL
