As I told you before. Now that I have it as digital I can edit out all
the
irrelevant soapy stuff and make the episodes much better.


I'm just curious, how long is each episode without the "soap"? Also,

25 minutes I think.

how well does the episode progress? It seems like the episode would
jump around erratically if you removed the character scenes (i.e.
"soap").


I've figured out that I can cut the opening soapy garbage from episode 1 and
start where the Doctor parades in front of Martha with his tie. The stuff
about the 21st birthday party is covered in another scene on the moon so the
opening rubbish with Marta's dad and the bimbo can all go. The soapy rubbish
and shouting match at the end can also be cut with a direct mix between
Martha listening to the news report and then standing outside the pub when
the Doctor turns up.


The problem with cutting out the beginning and ending scenes with
Martha's family is you drop the put-upon aspect of her character. If
she doesn't have to deal with all her family annoyances, she wouldn't
be go traveling with the Doctor to get away from them.

I can also cut out the stuff with the X-Ray machine
since it is not scientifically accurate, he's only giving the henchman the
does of 1/4 of a chest X-Ray.


I'm claiming that the Doctor meant 5000 times, not 5000 percent.
Also, the henchmen's species is sensitive to X-rays, so the brief
exposure will kill it.

As for the shoe part, while it doesn't make sense for the Doctor to be
radioactive afterwards, maybe he meant that for the X-rays that he
absorbed, he was able to turn the excess energy into heat, which he
directs into his shoe, which is why he wants to get rid of it so
quickly.

Yeah, that works.

Now the problem is how to re-edit the load of
nonsense with the MRI machine which would have to be more powerful than the
sun in order to do what the old woman claimed it would do.


She altered it, giving it a separate energy source in the process.
That is why it was able to use so much power and where that power came
from.

She is going travelling because the Doctor's got a time machine, not because
of her family. Otherwise show would not be abandoning becoming a doctor.

since it is not scientifically accurate, he's only giving the henchman
the
does of 1/4 of a chest X-Ray.


I'm claiming that the Doctor meant 5000 times, not 5000 percent.


Oh... is was 5000% was it. Right, I assumed 10,000. That's only 1/8 of a
chest X-Ray at the distance he was standing then and 100 times that is 12.5
chest X-Rays which 8 times less than a CT head scan.

Also, the henchmen's species is sensitive to X-rays, so the brief
exposure will kill it.


There are more X-Ray's and Gamma rays coming from outer space and hitting
the moon because it does not have an atmosphere so how come it hasn't died
from them?

It's complete and utter nonsense. The only rational explanation would be
that he was larking around and any decent script editor would have thrown
the script back in RTD's fact and told him to fix it and provide an
scientific explanation or else cut out the scene.

2) A separate energy source would have to be more powerful than the sun and
in fact the equivalent of a super nova gamma ray burst in order to fry
everyone neurons as she stated.

1) Where did the power come from in the first place when all there was was a
hospital generator which is simply not powerful enough. We did not even see
the lights flicker.

3) If it was coming from the Judoon then they would have switched it off
when they left.

4) The MRI coils and circuits are not capable of dissipating that much power
anyway and if she had that much power at her disposal she would not need an
MRI machine anyway.

5) This looked like a last gasp effort for revenge and was not pre-planned,
since there are no scene establishing that she made prior modifications
(since all the time that could have been devoted to such a build up wes
wasted by soap). She looked like she only came into hospital because she was
feeling un-well and it was bad luck the Judoon has traced her by this time.

Well, the fag smoke ceases to be a problem after July 1st this year, as

I'd say they should ban alcohol from puns too. Makes as much sense.

The problem with cutting out the beginning and ending scenes with
Martha's family is you drop the put-upon aspect of her character. If
she doesn't have to deal with all her family annoyances, she wouldn't
be go traveling with the Doctor to get away from them.


She is going travelling because the Doctor's got a time machine, not because
of her family.


She is able to go traveling with the Doctor because he has a time
machine. If it was only a spaceship, then she wouldn't be able to go
traveling because she can't just leave her life behind. However, she
does need a break and being able to go on an exotic trip and then come
back exactly when she left is the perfect way to do it.

Otherwise show would not be abandoning becoming a doctor.


I don't know what exactly you mean by that. I'm guessing you mean
"she would not be abandoning becoming a doctor." Except she isn't
abandoning her career. She's going on a trip and then she's going to
come back as if no time has passed at all. That's the difference
between Martha and Rose. Rose could leave everything behind (which
Jackie and Mickey hated) but Martha is just taking a short trip before
returning to her life, just as she left it.

I can also cut out the stuff with the X-Ray machine
since it is not scientifically accurate, he's only giving the henchman
the
does of 1/4 of a chest X-Ray.

the moon because it does not have an atmosphere so how come it hasn't died
from them?


The henchmen are inside the forcefield, which can assume takes care of
the radiation and even if it didn't, the henchmen are far inside the
building so the many walls between them and the outside would protect
them. So, the explanation that the henchmen are sensitive to x-ray
radiation still works.

As for the shoe part, while it doesn't make sense for the Doctor to be
radioactive afterwards, maybe he meant that for the X-rays that he
absorbed, he was able to turn the excess energy into heat, which he

There are plenty of examples of the Doctor being silly, such as just
about all of the Tom Baker stories. If Tom Baker can be silly, why
can't DT be silly? Of course, I still say the energy transfer
explanation still works, even though it is a stretch.

Now the problem is how to re-edit the load of

1) A separate energy source would have to be more powerful than the sun and
in fact the equivalent of a super nova gamma ray burst in order to fry
everyone neurons as she stated.


Yes, that's true but as long as the energy source was more efficient
than the sun, then it really isn't a problem. After all, if the
plasmavore provided the energy source for her weapon, then it's alien
tech and you can always get away with things like that with alien
tech.

2) Where did the power come from in the first place when all there was was a
hospital generator which is simply not powerful enough. We did not even see
the lights flicker.


See the next point

3) If it was coming from the Judoon then they would have switched it off
when they left.


Maybe they did. They switched it off when they left. Of course, they
also teleported the building back when they left so no reason they
couldn't do both at the same time.

4) The MRI coils and circuits are not capable of dissipating that much power
anyway


That's why she had to alter it. We did see her working on it.

and if she had that much power at her disposal she would not need an
MRI machine anyway.


Maybe she needed a foundation to build upon. After all, we've seen
some weird alien tech in Doctor Who, both old and new.

5) This looked like a last gasp effort for revenge and was not pre-planned,
since there are no scene establishing that she made prior modifications


She did say that she chose the hospital because it provided blood and
materials. Since she knew what was coming, it's quite likely that she
would make prior preparations, which we saw her do.

(since all the time that could have been devoted to such a build up wes
wasted by soap). She looked like she only came into hospital because she was
feeling un-well and it was bad luck the Judoon has traced her by this time.


No, she specifically said she chose to hospital and had been there for
a little while, in wait for someone to come after her.

Default Doctor Who progressive or interlaced? How to record it digitally.

While I was editing the current episode of Andromeda on ITV4 in order to
test out my new AVI/DivX/Xvid capture and editing software

(VirtualDub-MPEG2
1.6.15) which I recorded using the Xvid real time Codec set to interlaced,

I
noticed that the episode seem to have been either deintelaced at source,

ie.
by the broadcaster, since there is no motion blur in any of the frames

where
you would expect them to be such as rapid arm or hand movements.


Are you capturing using an analogue card plugged into a set top box?

I used to record the analogue transmissions with an analogue TV tuner card
(AIW 9000), but the digital reception is better here than analogue (even
though this isn't an official Freeview area) and I got tired of the 4
channels of dross so got a Nebula digital TV card for the PC in order to
watch 40 channels of dross instead. I record the mepg2 direct instead of
messing with on the fly compression, as that just adds another chance for
the quality to drop. Three 45 min Who eps fit on one 4.3G DVDr, though
sometimes that takes a bit of re-encoding (done by the authoring sw, or run
through DVD Shrink after authoring). I'd rather not be messing around
recompressing on the fly to try and fit 6 to a disc, but to save only having
one ep on a whole blank I do sometimes try and stretch to 4 with a bit of
re-encoding if the picture doesn't get noticeably poor.

And now you are contradiction yourself when you said "If she doesn't have to
deal with all her family annoyances, she wouldn't be go travelling with the
Doctor to get away from them." Now you are agreeing with me in that the only
reason she is going travelling with the Doctor is because she can always
return home therefore her so-called family annoyances are and irrelevant
part of her character since she obviously does not find her family annoying.


I can also cut out the stuff with the X-Ray machine

building so the many walls between them and the outside would protect
them. So, the explanation that the henchmen are sensitive to x-ray
radiation still works.


No it doesn't since the forcefield is only keeping in the atmosphere since
it is along in light from the sun and if it lets in light it is also letting
in other EM radiation including X-Rays. Also on top of that the henchmen are
walking past windows so they are not being protected by any walls and
further more Cosmic Radiation can travel through walls and through metal and
still be detected by spark detectors in the middle of concrete buildings.


As for the shoe part, while it doesn't make sense for the Doctor to be
radioactive afterwards, maybe he meant that for the X-rays that he
absorbed, he was able to turn the excess energy into heat, which he

can't DT be silly? Of course, I still say the energy transfer

When Tom Baker was being silly is was to emphasise a plot point and to
insult the villains. David Tennant is being silly for the sake of being
silly.


Now the problem is how to re-edit the load of
nonsense with the MRI machine which would have to be more powerful
than
the
sun in order to do what the old woman claimed it would do.


She altered it, giving it a separate energy source in the process.
That is why it was able to use so much power and where that power came
from.


1) A separate energy source would have to be more powerful than the sun
and
in fact the equivalent of a super nova gamma ray burst in order to fry
everyone neurons as she stated.


Yes, that's true but as long as the energy source was more efficient

We are talking about something the power of a super nova which is as bright
as a whole galaxy. Now where is such a power source going to come from and
is she had such power she would not need and MRI scanner?

plasmavore provided the energy source for her weapon, then it's alien
tech and you can always get away with things like that with alien
tech.


Poppycock. The story failed to show any kind of power source whatsoever
therefore you cannot assume that there was one. Any decent script editor
would have thrown the script back in RTD's face for being totally plotless.


2) Where did the power come from in the first place when all there was
was a
hospital generator which is simply not powerful enough. We did not even
see
the lights flicker.


See the next point

3) If it was coming from the Judoon then they would have switched it off
when they left.


Maybe they did. They switched it off when they left. Of course, they
also teleported the building back when they left so no reason they
couldn't do both at the same time.


In which case no one was ever at any risk and the Doctor would have known
that. And on top of that it was never shown that she tapped into a Judoon
power device (as powerful as a super nova) so you cannot assume that she did
this. The plot should have explained this and it did not because the simply
was no plot whatsoever. If she used the devise to cripple the Judoon ships
which she wanted to steal then a) she would have destroyed the ships
computers in the process through the EMP burst making the ships worth
nothing more than scrap, b) she would have fried her own self without a
means of escape, which was never shown, therefore the script should have
been thrown back at RTD's face once again, and c) how could the Judoon have
a device that powerful anyway. Such a device was never shown. Davies,
script, face!


4) The MRI coils and circuits are not capable of dissipating that much
power
anyway


That's why she had to alter it. We did see her working on it.


If she had to alter it then the alteration would have amounted to building a
completely new machine since NOTHING in an MRI scanner could have withstood
the power build-up. Therefore she did not need an MRI scanner in the first
place. And if she could afford to buy or make the parts then she could
afford to buy a scanner direct from the manufactures so did not need to
highjack an entire hospital. Therefore what was she doing in a hospital bed.
Davies, script, face!


and if she had that much power at her disposal she would not need an
MRI machine anyway.


Maybe she needed a foundation to build upon. After all, we've seen
some weird alien tech in Doctor Who, both old and new.


Twaddle. The scanner could not have done the job and if it was one part she
needed from it to build a new device which didn't she buy it. In fact the
only parts that found on Earth would have been capable of functioning in a
new device would have only been the nuts and bolts holding it together. Show
what exactly did she need and what did it do? Davies, script, face!


5) This looked like a last gasp effort for revenge and was not
pre-planned,
since there are no scene establishing that she made prior modifications


She did say that she chose the hospital because it provided blood and
materials. Since she knew what was coming, it's quite likely that she
would make prior preparations, which we saw her do.


Which we did not see her do. And she could just mug someone for blood. And
why was it human blood she needed. Why not animal blood which is 98%
identical, considering she was an alien anyway with a different blood
chemistry?

(since all the time that could have been devoted to such a build up wes
wasted by soap). She looked like she only came into hospital because she
was
feeling un-well and it was bad luck the Judoon has traced her by this
time.


No, she specifically said she chose to hospital and had been there for
a little while, in wait for someone to come after her.


Ridiculous. She could have built a machine in her back garden and waited and
it would have been far more effective and would have no required any
henchmen. Oh an how come she was she able to pay them and transport them
half way across the galaxy an not afford to buy her own MRI scanner?

Ridiculous.

Doctor Who transmitted as progressive ie. every odd field is part of

DW is recorded interlaced at 50 fields per second, but digitally
converted to 25 frames per second. It is transmitted interlaced, but
for your purposes you can treat it as a progressive image, as both
fields ostensibly now originate at the same point in time. Having said
that, the end credits roller is probably 50 field interlaced, so if
you record that as progressive it will probably screw it up.


Thanks. I'll have to stick to recording it interlaced then and I'll see
if I can figure out a way of avoiding de-interlacing the 25 fps stuff
while de-interlacing the credits in Virtual Dub by masking the frames,
but this is going to slow down the conversion even when its not doing
any extra processing.

Run two operations on it, one for the main show&next week video and audio and
one for the rest of the credits, and then use the append avi segment once you've
encoded them both. You can probably encode the redits at 1/2 - 1/3 of the main
show without really noticing.
