Technical help request to elmo,Mauro and all expert videomakers

Hello my dear pro-videomakers !
I've a problem and I need your help.
Here I've posted a video I've capured yesterday:

(BTW : this is the last part of Carmen fruit-dish of yesterday.
In your videos I've not found this part.
If you can upload your version I will be grateful )

The quality is not good because the video is captured
from old vhs and then encoded.However the problem is another:

as you can see, when the camera goes close to a model
or when it moves quickly there are so many frozen frames
that the video becomes unwatchable.
This is not due to the recorder.
In fact it happens when I watch ETV in real time.
Other channels are perfect,the problem is only present
watching ETV and Sexysat and only when the camera is close to a model
or when the camers is moving quickly.
At the beginning I thought it was a problem due to the
poor quality of the bitrate of ETV and SSat, but
when I see your videos I don't see these problems.

Do you think it can be:

1) Diameter of my dish is not enough ( 90 cm ) ?
2) I'm receiving from Eutelsat.Is it a better signal on Astra ?
3) Other possible reason ?

Can you tell me:

I) Diameter of your dish ?
2) Eutelsat or Astra ?
3) Your capture device ?

I make you these questions because I'd like to buy
a digital device for video capturing, but first I have to
resolve the receiving problem I have exposed.

knowing your kindness I hope you will give me your help.

Thanks in advance

Bye

@ elmo:

Thank you very much elmo.

Have a good day

it may be 30 cm, I didn't measure it. It is for camping can be used from a car.

example the Hotbird MPEG .ts file from 06.00 - 11.00 today is 5.14 GB slightly more than a GB an hour. variable bitrate 2.55 - 2.63 Mbps.

the resulting direct stream copy to MPEG programm file is 4.86 GB with 12 data breaks 2.3 Mbps

@ all pro-videomakers
( especially Mauro, who had the same problem )

Do you think my problem could be due to the
amount of video memory or flash memory of the sat receiver ?

Thanks in advance
Bye

@ ghostwriter2008, elmo , Mauro , DB :

Hello pro-videomakers !

I'm sorry but yesterday was a hardwork day for me.
So , when I saw elmo's answer at 00:00 I had no more force
to reply and I went to sleep.

Many thanks to all, you are always very kind and professional.

@ elmo: 1) thank you also for the video
               2) are you sure ? only 25 cm dish ?

               3) If I've understood well, your recorded file is a .ts file.
                   How great is a .ts file for 1 hour of ETV recording ?
------------------------------------------------------------------
Have a good day

Bye

I'll add a little flame to the fire.

Digital tv (not HD) is encoded in Mpeg-2. The compression works by only recording changes from the previous frames - that is the simple explanation. the complex one is not really needed. Now if you have a long shot there are very few changes from frame to frame. Bring the camera in closer and there are many, many changes for your receiver to handle. If the receiver cannot handle these changes quickly enough then there will be picture breakup.

Looking at the vid, the breakup is quite severe but it does seem to be the fault of the receiver and nothing else.

There are several methods/equipment for capturing and these have been covered in earlier topics in this section so there is little point to repeat them here.

Seems like it's your receiver. I had similar effects with my Dreambox 7025, now I have a 600 PVR and the problem has vanished.

here the vid, Carmen fruit cocktail Pt2

I encoded at the same bitrate and resolution as the 1st part

I use a 25 cm dish pointed at Hotbird
the LNB > Eye TV 300 > iMac Intel Core 2 Duo 1.83 GHz with 2 GB SDRAM onto an Extern USB or Firewire HD.

I record the Hotbird MPEG ts file straight from the dish.

last year I had a flirt with Win XP on the same machine using a Terratec S USB device. the results were identical. Using this method with the Astra signal. After ETV changed their frequency last spring/summer, the amount of useless information in the ts file (About 1,5 - 2 GB per show), was the deciding factor for me to switch back to Hotbird.

ETV at times, send a really crap signal, with lots of data breaks. there are very often many packages missing, which is more difficult for a digital to analog converter to process ( as Mauro wrote above, crap receiver for example). hence the buggy picture. You then record to tape and re convert to digital. At every step you are adding to the problem.
