Infoseite // Hi8 archived - NEW OPPORTUNITIES 2009



Frage von PixelPaule:


Hello,

I know: the theme is old and actually done.
But the next technology is advanced and old Hi8 tapes are still untouched in the cupboard.
Meanwhile, there are 1080p, new compressor, etc.
It may be a revision of the approach shown.

The problem is the old:
Hi8 copy for the purpose of conservation, quickly, without much editing, in a quality-resistant format (digital). Should be playable example of DVD, in an environment of full HD LCD TV (1080p), DVD player.
But synonymous next processable, ie can be cut without loss of quality.

The old road (2005):
graphics card with video-in -> VirtualDub 720 x 568 UYVY unkompr. -> MGEP-2 -> DVD, then DVD -> MPEG-2 -> Premiere ---> MPEG-2 -> DVD.
What is it made in 2009?
Are there new opportunities and tools, codecs, formats, etc.

I do not know where your problem lies now. Hi8 HD has nothing to do with new technology or to be done. Hi8 and is still SD. You can create your Hi8 tapes to PC überpsielen (but your way through the graphics card, I would NEVER go synonymous and do not recommend. Because nothing clever to get out) and then edit infinite, as they now are digital. Then you can rausbrennen they wish to use a normal SD MPEG2-DVD and synonymous with the latest television sets (Full-HD, etc) anschauen.

But what is not to recommend: Try your Hi8 tapes afterwards digitally on HD aufzublasen that goes wrong. Hi8 nunmal is not HD, so you have to be satisfied. Is therefore synonymous clear that there afterwards on a HD-32''Plasma Screen synonymous not just stunning looks, but more can you just do not worry ...

Antwort von PixelPaule:

The path on the graphics card provided demonstrated a good result, that is not the problem.

Endless processing of digital material is of course not possible, at least not in Komprimiereung (Mpeg-2) and Neukomprimierung.

The problem is the balancing of the archive format.

Normally the procedure would be as follows:
1. Digitizing (uncompressed or lossless)
2. Cutting (transitions, sound, fonts, etc.)
3. Compression (MPEG-2, DVD) and burn

The specificity arises out of the desire of the archiving of the raw material. In unpromierter form or eliminates loss due to the amount of data from. So must be compressed (MPEG-2?).
The cut must be in the compressed format will be set up. For quality reasons, the frame-accurate editing without Neukomprimierung possible (smart Reendering). Thus, the final format of the archive format already established (Mpeg-2).
2005 was the solution MainConcept plugin for Premiere.

The question s.die experts: there are some 2008 Newer, cheaper, better, etc.

Hello,

the mag for you to be. The graphics card is synonymous but in my opinion, not for an error-free digitization of analog video capable. This begins with the Resolutionan goes beyond the issue of Tonversatzes next and finally stops when the CPU load is not on ... For several hours of video capturing one, even for the annotated long-term archiving, very bad condition.

Real consumer video cards are used to with a maximum data rate of approximately 3.5 to 6.0 MB / s. captured. As a "MasterCard" synonymous longer without Tonversatz projects and in a very good consumer quality. If one is compatible with DV wanted to be, a corresponding conversion of the tapes - no preference whether it's Cam with analog-in or a converter - made long ago. Thus, real-DV files with 48KHz stereo, etc. A better option is not synonymous 2008/2009, based on the quality and compatibility. And "HD-inflated" Hi8 / SVHS video is about the quality rather just be worse and beyond just wasted unnecessarily place ...

If you have High-quality want, you need every few years as a professional advice, you your uncompressed video projects on the current media in the best quality copies, etc. Then all you need to make sure your file is uncompressed video on a currently readable, well-equipped with current interfaces, data subject. But this may indeed synonymous then determines a company take over ... In contrast, MPEG2 for archiving is not likely to be very lossy.

Otherwise, nothing is for eternity, even though it has been almost 20 years, no real problems. But this is only my opinion.

Yes, because I give thee quite. My statement was more pointed terms, that you are in comparison to the analog processing of the material can handle much longer than with analog equipment.

Why necessarily Mpeg-2? I will give you fairly, that a loss-free storage very much space would occupy, but there is not only lossless and Mpeg2. How about it as if you have your material in a much less compressed format save as Mpeg2? For example, by using an analog-digital converter. (How 'Vaio' synonymous already mentioned) the analog signals will save the top in quality than DV-AVI files (how those files that are created when you with your digital video camera via FireWire aufnimmst) on the hard drive from. An hour of video correspond to 13GB. For me, this is more than acceptable, because in my opinion, needs good quality just a place synonymous.

I would therefore valuable to digitize analog tapes synonymous never have a TV card (and has no first right graphics card), which equal the signal cheap and lossy MPEG-2 Format. Then of course you continue with these problems "is not frame-accurate cut," etc.

Professional or semi-professional companies perfectly synonymous with the help of a digitizer such a converter. A better than Abspeicherformat of the transducers produced DV-AVI is my opinion only the loss-free, but that I would under normal circumstances advise.

"Pixel Paule" wrote: Thus, the final format of the archive format already established (Mpeg-2).

If you have an A / D converter uses the archive format is not MPEG-2. I use an archive format DV-AVI format, which the converter generates. Need even more space than MPEG-2, but it is one of loss and can therefore size without concern for archiving applications. And the hard drive prices are now synonymous not so expensive. With a 1000GB external plate, because it fits a lot s.Archivierungen it.

For your MPEG-2 format: The one where MPEG-2 I is used, is when I cut my finished movie as a copy of view, NOT as archiving to DVD burn. A video-DVD, I would NEVER use as archiving, especially not if the latest reports on the durability of DVDs has read where quite bad of me is ...

Otherwise, for me the digitizing process as follows:

1) Very good playback device
2) Analog-to-digital converter (of Analog to DV-AVI format)
3) Save the incoming DV-AVI files on external hard disk storage
4) If I use these files still in the editing program would like to edit, can I do this, otherwise I have already archived and am ready.
5) If I have the edited version synonymous archive wants to do I export the movie from the editing program is also in DV-AVI format and save it, along with the raw material on the external hard drive.

Antwort von PixelPaule:

OK, thanks for the answers and hints.

The following observations about this:
1)
The capture on a graphics card (uncompressed 720 x 568, UYVY) with video - In takes place in real time, which is not my opinion.
A cassette is now loose on a Fetplatte.

The quality of these Zwischenspreicherung is good and largely of the quality of Hi8 recordings provides more will not be out (except through filter of course).

So there is no immediate need s.neuer hardware. A bad Resolutionist argument is not synonymous with Hi8.

The problem of Asynchronität I take seriously and will examine it.

2)
MPEG-2 is in fact interchangeable. This was aimed so synonymous my primary question.

The DV codec is certainly an alternative. Is there information on how to as unbundled comes? Can you buy it separately, who offers him?

3)
The archiving on a DVD should be, I had not before. DVD playback is the medium clear. Backups should always be redundant. However this is considered separately.
Incidentally, of bands I do not think much, if they are synonymous digitally described. A SAN system with redundant hard disks to me but I will not build synonymous.

4)
Core remains the subsequent processing. Archive material (crude and cut) in the same format should be stored. This goes with the DV codec obviously synonymous. I assume that I am here just forming and largely without Reendering can intersect.
This goes with mpeg-2 and Maincocncept but synonymous.

My test in 2005, but I recall, that when compared to several Reendergenerationen Mpeg Mjpeg advantage was. Applies perhaps no longer.

I would not say so directly. The final quality is primarily of the playback device dependent. The actual quality of Hi8 recordings comes s.sekundärer body. Should read: The playback device is the first link in the digitization chain, so it is decisive for the quality. If you now have a ausgeleierte, 10 years old Hi8 camera used is of course produced a poorer quality than if the player hardly used or is not worn. Not infrequently achieved with the careful choice of the playback device and determining the best picture and sound quality ... Many think that the old analog tapes, not much could rausholen, but only a clean, neat playback device can work miracles here!

As an "alternative" I see the DV codec, but as the only reasonable way to an acceptable quality to be archived. I would never in MPEG-2 archive ... The DV codec, which is the analog-digital converters of Canopus is used, is a hardware encoder and is a specially manufactured of Canopus codec. But since you're of the opinion that "no immediate need exists s.neuer hardware", you can probably only on software codecs fall back to where I tell you, however, no information can be synonymous and I'm not sure whether an equally good quality to achieve ...

We know there is a disturbance s.Rand, on the CRT TV is not presented, the "motion area" is smaller.

Therefore, I have a letterbox at the Motion Area herumgelegt and am at 720 x 576 remained without resizing.

The further transformation into mpeg or DVC provides par 1067 instead of the expected 1.094. Is my calculation as yet?

Furthermore, the images on DVDs, no more edge, that I should probably change now. What makes sense?

A Resizing a suitable chosen Motion Area to 720 x 576, or 704 x 576? Or here is a quality loss?
The letter maintained? Only the Motion Area Save?

When it is a necessary but probably Resizing meaningful, for the initial digitization, archiving, or when only when editing?

In the editing program you can use it like any other material edit and then output to DVD. Either you can the make your editing program (which is the encoder of your editing program to use) or you can render your file in the editing program (also re-DV-AVI) and uses a different software like EncoreDVD (which I always use). There is abundance synonymous freeware programs to DVD, but in such programs is the quality of the encoder used questionable and very gewöhnungsbedürftig.

The crucial difference is that the video via firewire - / and digital audio signal is recorded. When using a transducer (or DV-CAM with analog-in) or less for the PC on a silver platter served. This must be the digital data only "One to One" take over, or to HDD copy. No capturing or walk, etc. The graphics card is completely meaningless. In terms of quality - and synonymous to the image stability - there is no better way for old analog material. Another advantage: For a DVD, the data already in a compatible Resolutionvor. Both video - as synonymous Audioseitig (720x576 in 16bit/48kHz). The files must then "only" in the MPEG2 format to be changed. Either the editing program or the software itself

"... But how do you take the certainty that this will increase the quality significantly increased ?..."

Ok,

the PC will not be charged, only reads data. I could continue to use him. Is an advantage, but not interesting for me, I need it then not.
Silver platter, beautiful and good: two settings in VirtualDub and I directly create computer hardware, the same codec.
Better quality would be a reason, but I doubt. Nobody seems to be the experience with the Philips chip made and can compare the quality.

But I suppose a point to the possibility of a new computer with DV Cam - In. This provides an additional storage option in the DV codec.
There were probably cameras (Digital8), which were synonymous Hi8 play. But are probably no longer to get and in any event no longer current.
Thus, the path is now well on miniDV and Hi8 connect the camera via DV - In.

Then I have a normal copy operation between two Recoder, all without a PC, right?

And (later) I can edit miniDV via firewire directly to the PC drag.

Which camcorder format is recommended, or what your camcorder?

This solution is for me a very practical advantage, it appears achievable quickly: camcorder tapes and buy everything and in turn to copy. Previously, perhaps the old Hi still waiting.

I think you understand the whole thing with the transducers, somehow wrong. These converters produce not just a DV format, they prepare the incoming signal is still synonymous, with the help of an integrated TB are so similar as jitter and reduces and eliminates interferences. The ADVC-300 also has the opportunity through a variety of optimization software provided, so you have influence on color saturation, brightness, edge optimization, etc. have.

The result has failed car BETTER QUALITY, synonymous if you ever doubted the will.

With the Camera to Camera Solution, you ansprichst, the data just as with a digital converter and stored digitally on MiniDV, BUT without that you have influence on optimization settings and that would have reduced disruptive. But you have to be an external TBC intermediate switch, otherwise the interference with flat land and then digitized on MiniDV. If you do not bother, it's OK.

Strictly speaking, there is only one way the analog signal to be improved.

Precisely these issues I am currently synonymous. After mature consideration, I must as a scientist say quite clearly that fasting actually sees no way more hard s.externen passes. One should keep in mind:

- What is provided in a secure archives worth? What are ¬ 200 for 2x 1 terabyte hard drive? Or who certainly wants to go: 3 hard disks, all s.unterschiedlichen, dry, cool storage rooms? In a few years we will laugh about such questions, because you then for ¬ 100 not 1 only 5 terabytes of memory gets.

- Security? Of course, a plate full time or part (sector) break. But the biggest enemy of hard disks is HEAT, ie the "half-normal" are based on the assumption that the disk is used daily. And realistically, I know people who have a 10-year-old ALDI PCs. Until today, no defect occurs s.der plate. The quality of the plates is always next to, failures are increasingly unlikely ...

- Redundancy, ie a copy of the second security panel s.einem storing takes place against the risk 0. 100% you will get little.

- Every few years could be a few Euros in hand and a plate, etc. buy the whole video archive to 1:1 copy and s.einen bring safe place. The "old" boards are moderated and will remain as long as get up really a defect occurs.

The conclusion seems to me to be dangerous:
1. The price war in the HDD business is becoming more brutal, because every cent counts. Why should the quality to rise under these circumstances?
The development cycles are getting shorter and shorter. Time for extensive durability test, there is less and less secure place.

2. The long-term storage does not correspond to the ordinary use. Consequently, it is synonymous certainly no great value in the development laid out. I know some cases of HD failure, which happens just after the first or second operation occurred after a long time have not been used. Heat alone is not the only reason for the failure probability determined.
