5042.0. "Blender or Time Base?" by KAHUNA::SUMNER () Fri Sep 13 1991 13:28

    Hi again!
    
    Has anybody used or heard any good or bad comments about the Video 
    Blender?   I'm thinking about using one instead of investing in 
    Time Base correctors.  What to you think?

5042.1Toast anyone?SDOGUS::WILLIAMSTOPGUNTue Sep 17 1991 22:2920
    Ray,
    Do you already have a Toaster?  If so then you might just need to get a
    TBC and be done with it.  I haven't tried the blender yet, but I'm
    having a blast with my toaster and my TBC!
    
    I'm not using the Personal 1000 TBC, but I am instead using the new
    external one with two video inputs (synched and gend) (SVHS all the way
    thru, etc.).  I was fairly disappointed with most other video things
    for the Amiga (e.g. SuperGen2000 was okay, but the SuperGen and the
    perfect gen, etc were just not very usable.)
    
    I've also seem to have found a strange thing with external Genlocks,
    seems I can get a harringbone pattern on an external Genlock quite
    easily, but not on an internal genlock.  The way to generate the
    harringbone is to not have a signal to genlock with.
    
    If I hear anything on the Blender, I'll add more to this note.

   Could you tell us which TBC you are using, and the current price? Thanks.

    My freindly dealer was not very impressed by the quality output of the
    blender he had to sell, so much so, that he was sending it back to
    Progressive.
    
    Since the above could be slanderous, because I did not see it for
    myself, just consider it a warning and see for yourself BEFORE you make
    ANY decision.

    	The Personal 1000 TBC is working great for me. I'm using it with
    AG1960 VCR and a toaster. I setup a toaster and Personal TBC for a
    local post production house. They are using an external timebase
    and like the results.

Jean,
    Actually, I think libelous is correct since this is seen as written
    material ;^) ;^)

    >> What kind of TBC do you have?
    
    	Video inputs  A and B (BNC or S-VHS [on the SC models]).
    
    	Video outputs A and B (BNC or S-VHS [on the SC models]).
    
    	Peaking controls and RS170A output.
    
    	External to the A2000 or A3000 (if you want to warp your case).
        The external is fine with me, because I've got more room on my
        desk than in my machines.
    
    	S-VHS is Y/C seperate all the way through. 
    
    	Video A and B are synched
    
    	And the envelope please  ---->>>>>
    
    	Showline 1000SC is the name of the TBC.  It costs retail about
    $2600.00, but consider the following.  Dual input AND output!  You need
    to have two personals to do that at retail $1000 each.  You need to
    have a method of synching them at $600 each.  And you still don't have
    true Y/C all the way through as well as not having peaking controls!

    re .5
    
    	The Personal TBD is not Y/C in and out but neither is the video
    toaster. The Personal TBC does a good job at transforming the Y/C
    into RS170A ( composite, a form the toaster likes ).
    	As for Syncing two Personal TBCs together ..
    The Personal TBC has inputs and outputs that allow them to be
    synced to an external reference or provide the reference for other
    TBCs. No extra hardware required.
    	$1000 is list price. The market price for new Personal TBCs is
    about $750.
    
    	The one thing it is missing is frame capture and some of the
    controls. The Personal TBC is made to be set-up and left to do it's
    job.

    So what?  I really don't understand.  The importance as to whether the
    Y/C is on the toaster is completely meaningless as near as I can tell. 
    The toaster is an RS17A device completely.  True Y/C IS important if
    you are using Y/C!  Either as an input device or (even more so) as an
    output device.  IF YOU MIX Y/C AND THEN BREAK IT OUT AGAIN YOU WILL
    DEGRADE THE SIGNAL!!!!!!!  VHS IS NOT THAT GREAT TO BEGIN WITH!! S-VHS
    IS IMHO ONLY MARGINALLY BETTER!  But it IS better!  To mix the signal
    and break it out is to virtually destroy the advantages of S-VHS.  If
    you don't believe it RECORD IT!  Toaster gives you a (close to,
    although NewTek claims 'perfect') video signal.  It is what you do
    before and after the toaster that matters!
    <flame off>
    
    Whew, this flaming is too hard to do.  I'll try a little more relaxed
    version.

    Never said it didn't.

    No extra hardware, except for the fact that you need an extra TBC to
    get the second video input to be sep.
    
   > 	$1000 is list price. The market price for new Personal TBCs is

    Still we are up to $1500.  However I always compare retail and then
    look for the best market price because market prices are not
    comparable.

    Many of the TBCs are left to do the job.  If you live in a static video
    environment then that is all you need.  If you need the ability to
    adjust (professional) then you will need to be able to get to some
    controls, etc.

    Steve, I really do apologize if I sound like I'm flaming you.  I'm NOT! 
    I was having fun.  I used a Personal TBC and didn't like it.  But as
    most things in Video, so much of the quality of the output is
    subjective.  Output quality is affected by Monitor, machine, tape,
    cables, etc.  I'm sure the Personal TBC is okay.  It wasn't for me.  My
    wife is doing this stuff professionally and she couldn't get the
    quality output she required especially for her S-VHS customers.  So I
    popped in the Showline 1000 and with one equipment change, the problems
    were solved.  And I got rid of two TBCs in the process!  Still
    subjective.  I ran the signals thru my scope and vector scope.  The
    output from the Personal just wasn't up to the Showline.  Still very
    subjective (what was the humidity?  what was the S/N ratio? what was
    the power stability over the test?).

    re .7
    
    	The comment in .6 about the toaster was in reference to the early
    ( .0 .1 .2 ) notes that suggested a Video toaster might be the reason
    the person was interested in TBCs. If this is not the case and the user
    has S-VHS or HI-8 equipment then the Showline TBCs have a big
    advantage.
    	But if the user has VHS then the lower cost of the personal TBC
    would be an advantage.
    
    	As for "It is what you do before and after the toaster that matters!"
    This is also true and one of the reasons I'm in the process of
    upgrading from AG1960s to 3/4 inch U-matic equipment. I have set-up
    and played with a toaster system connected to ED-Beta equipment and
    the results were much better.
