Frage von Daniel_:
Welcome the forum!
I've made some time rummaging through the Internet to provide information to digitize video of get. Somehow I think of my scenario is not the right solution. So:
I look after a network in a practice. There is an echo device for the increasingly expensive Sonyzur digital archiving of backup tapes must be purchased. At the same time but there is still a synonymous SVHS recorder tuned for each echo earlier been archived on video. My idea is now ripe to depart SVHS signal to digitize and to store it on a server. Cost savings and benefits would be first, second, you could see the echoes of any PC.
My questions are now:
In what format should I convert the data? You must be as small as possible, here comes a month been together a lot.
What software would you recommend? Thus, the assistants have to come to terms synonymous.
As far as I can see a hardware conversion, the best solution, but what would be?
Thanks and greetings
Daniel

Hi,
I fear you underestimate the amount of data that is there's always times more powerful ... just as a note.
The problem will be the amount of data already in the lap recording, drastically. This expensive equipment is required.
A normal, well-equipped Calculator, economy recorded it live safely synonymous nor mpeg1 / 2, MPEG 4, the no longer walk.
Normal A / D converter record in DV format, which has a compression ratio of approximately 5:1. Ie ca.13GB/Std.
Simple A / D converter, the relatively high quality of walking, there is relatively little money for canopus (ca.170,-teuros). The data would then be subsequently changed for example in mpeg4 (DivX). It costs a lot of additional time Therefore, the data is drastically reduced. Depending on the quality setting.
To make it short. The Cheapest and easiest solution is still the tape.
Otherwise: Purchase a DVD recorder and let the data sizzle immediately on DVD, or a hard disk recorder and then on DVD ....
Then You Need "only" have an automatic DVD archive and off you go ....
Seriously. When the Sony tapes are so expensive, then archiving easy to SVHS. Then, although no direct access possible, but the costs are not synonymous explode.
Alternative: A DV Cam with analog input and record to DV tapes. Since then the piece will cost around 2 euros.
Cheaper but still the DVD solution.
It has moreover a very good reason why synonymous still the No.1 acts as a backup tape (in the computer) and not just stop there. Most sure that your camcorder has a DV-in so that the finished movies back to back onto tape, as cheaper and safer gehts never.
Antwort von StefanS:
Since you have a nice job. There are surely many ways, but we ought to be limited to a very simple and pragmatic approach, if we keep in mind that at any later date "is not PC and video professionals" to look at the pictures.
For me and so my advice is s.Dich all-important question, should in any resolution, size and quality of the recordings again be available and intuited, and what media are to be viewed on these recordings.
After that it depends on which one to use format.
Consider the following:
1 minutes film:
DV-AVI (the format of today's mini-DV camcorder): 210 MB
MPEG2 (the DVD format, eg at 5 Mbit / sec): 35 - 40 MB
MPEG1 (the old "VCD" format = 1150 Kbits / sec): approx 9 MB
For other formats (DivX, Xvid, etc.) I can for compatibility and user safety is not guessing.
The playback size and quality can you as an administrator of a network of your Docs certainly play again, to define its requirement to be able to.
If you know that, we should discuss here next, what software and what solutions can be an automated and therefore suitable for you.

Antwort von Daniel_:
I know of another doctor who makes the same procedure with a Typhoon TV Capture Card and is reportedly very good results with this. He speaks of 3MB for 1 minute video.
Therefore I think that the images of the compressed echoes can be really strong.
I guess DV is not appropriate when there together as much data. In practice, while standing at about 1 years old, but aged office computer.
I suspect from synonymous Zeigründen would s.besten a real-time MPEG encoding. Has it not be with the greatest scope MPEG4??
Thanks for the speedy answers!

Antwort von coconut:
TV card works, but with quality constraints.
If the same one that TV-Card Hardware moderately compressed in mpeg.
3MB for a minute is already scarce.
As Stefan has already written, it depends of the data rate and the size (resolution = ab = detail), which meets s.Daten.
For example, if the data stream to 400kb/sek in mpeg1. is limited, one comes with some 3MB/min. out.
The Resolutionwäre typically 352x288.
A DV Resolutionhat 720x576, which is almost double the size = about 4 times the amount of data.
SVHS has usually 352x576. The picture is compressed for viewing on 352x288 "" and is significantly better in the resolution.
The figures relate to a play with a normal Fersehgerät.
For a computer display, the whole must be interpolated to a different size such as 480x360 or 640x480.
Then you sharpen but lost.
Try is here announced.
PS. MPEG 4 yet kompriemiert stronger, but it lost more details are synonymous. As would discourage cih of. Especially because it means extra effort.
Antwort von Daniel_:
What kind of hardware you would recommend to convert? I have often read that a TV capture cards do not provide such good quality. Could you recommend me a card? Or is a pure MPEG encoder card be better? Perhaps there is a good middle synonymous.
I think I'll try it then with MPEG1 and an interpolated solution. The very fact should only be played on computer screens.

whoever you want to read the whole thread here, because then give you a sensible answer. Slowly I see black for our physicians and the health system.
On the one Page You've heard that TV cards should not be so great, on the other Page You put on MPEG1 and an interpolated solution. Comparison to every current TV card're almost high-resolution HDTV.
Define but for once the request by you, as I have already written to show to your doctor once a few examples, the position to assess this, namely, how can the Picture geschaut the baby and do not know on what comprises a boy a girl because the Schniedel is no longer visible.
If your doctors have replied to you then, the image quality they need (your doctors, not you and not us!), Then you login again and give us this request known, so that we can answer this properly, that is targeted.
And now tell me please, what city You take care of your doctors, for safety.

Stefan
Antwort von Apprentice:
Unfortunately, I stand in front of a chicken and egg problem. How should I show examples when I lack the hardware. And how can I define the Harwareanforderungen if I have no examples.
And I thought Coconuts contribution can be taken from that MPEG1 and Interpolation may be suitable.
I write here is not without reason, newcomers to the forum.
Antwort von StefanS:
Ok.
So far, every response to S-Video has been archived.
What is the reason S-Video? Just because it was fashionable and new, and has the cash to pay the doctor or because the difference in quality needs to regular VHS, to be sure of his diagnosis, to identify sufficient details to be able, etc.
This question will probably be able to answer you your doctor.
Option 1: VHS would have been sufficient
Then synonymous enough for digitization one Resolutionvon 320 x 240 up to VideoCD Resolution352 x 288th -> MPEG1
To show your doctor this, you only need one of your computer buddies of times a VCD, which certainly have a short somewhere, or can create to borrow it, and it your window in Doc s.Computer s.im Origignalauflösung and b) in s.Computer demonstrate full screen mode.
Option 2: S-VHS was a must (says the doctor!) Because of the quality
Then we should save ourselves the VCD and less waste. We need an MPEG2, at least in S-VCD quality (480 x 576), more available in DVD quality (720 x 576 and) appropriate data rate,
These examples should be your local computer buddies in a position to give you.
Should you have any problems so that, sometimes betray your site, because most likely is some forum participants within reach.
Regardless of how and where did you get in front of you administered network to secure the individual files, catalog them and for whom they think of where to be found? That is only incidental, as it has nothing to do with your question, but I'd be interested to solve your problem entirely times. And that is so, because then I can warn just before the "permanent" storage for at least the remainder of the patient's life expectancy to be adopted on a DVD.

Antwort von coconut:
avails wirlich only try.
None you can say here, as the requirements ( "your" doctors).
If somewhere was achieved through a TV card sufficient results, I would be the first to try.
Otherwise you will not get stuck.
Proposal: Obtain you a TV card (eg on ebay) and tests ....
To change the size, in VirtualDub. The filter "resize" Reload and test the different parameters.
Pending the result should be 480x360 (for S-VHS) useful.
But you must try now already own and seek the verdict of doctors.
Antwort von Daniel_:
Then I'll get now play the first time on a VCD and a SVCD. I was able to have learned that a week together approximately 240 minutes of video.
As written in the first post of the videos will be archived on the practice server. This is s.sichersten and can be accessed of any computer on it. From there, every day via VXA-2 backup drawn. This is synonymous to ensure the sustainability of the data. However, I doubt that this is a true criterion. Finally it was up to now archived at SVHS.
I'm just worried that rises through the video data of the capacity needed to dizzying heights.
Good, for whatever reason, S-video. Unfortunately, it is in the medical field so that there are a few vendors, who split up the market. I think there are even only General Electric and Siemens to offer the echoes. A new echo costs accordingly. The devices start at about 50k I think ¬ and end somewhere in the range of 250T ¬. The synonymous words, is widely used only the "best". Sure you know the huge devices. And in essence, only a small tinkers Windows machine, where you will be hindered by the fact Hardwaredongel enter the operating system. The Manufacturer synonymous to do everything to earn even more coal.
This is the strangest synonymous s.der History: The data is stored digitally and converted to analogue, so that they can record on video. And I'm trying to digitize the data again, because there is no other option. The Manufacturer's intention to see with no other option. The network solution Archives of General Electric synonymous costs another just in the middle 5-digit range. Only the software!
