Although similar already discussed, I come after several days of preparatory work is no longer next.
Starting position: I have a lot of S-VHS tapes on which endoscopic images in a rather critical quality are included (small picture, often overwhelms or dark but then again, often started recording). This material should now be viewed and the unimportant / worst shares herausgeschnitte be. This new material will be possible without loss digitized and cut with the possibility of them on DVD or S-VHS possible with little loss to archive. It is the image quality and stability in the foreground. That means I need a stable editing software with the most fundamental ways to the changing brightness of corrective action.
When I think of digitizing s.die Canopus ADVC-300, in the hope that the S-VHS material through the conversion and the Canopus codec suffers less. Accordingly, I consider synonymous Edius NX Express to favor (advantages?). If I have understood correctly, these are but only by the Edius software fully supported, but just when keyframing probably unsatisfactory works. Adobe Premiere Pro 1.5 is likely to support (I have to 1.0 and was rather disappointed) and not the current version of CS Or Avid Liquid Pro offers better / similar quality to my concerns
Then an understanding question: What quality level is necessary for digitization? One loses information when it is not the highest, or extends a lower data rate according to the S-VHS material?
I realize that it is not the optimal solution and a lot of conviction and faith issues. But maybe someone has similar problems already solved successfully.
Already many thanks in advance for the efforts Phonas

I enjoy being corrected, but as far as I know, the Canopus DV PAL parts and nothing else out. That you are in any case, quality over S-VHS, with other words, your result will be more of the quality of the playback recorder determined as of everything that comes afterwards. With what software you then want to edit, depends first of only your taste and your needs from. Relevant quality in software is only the existing MPEG-2 encoder for your videos on DVD to bring. To find out what is in this point well and less well, there's tests.

In DV Digitizer does not simply "better than S-VHS". DV dir erstmal throws away a lot s.Farbinformation (PAL 4:2:0) and then the codec must still analyze the image content and in its 25Mb / s pressed. If you have the budget for this, I would advise you of professional Capture Cards AJA or Blackmagic view. FCPS ProRes codec (4:2:2 and I-frame) is an alternative to happy HDuncompressed taken should be synonymous with SD material will not be wrong ... Good luck!

The color resolution of VHS and S-VHS is not even 4:1:1. The Farbträger when recording at a lower frequency decreased, the bandwidth is limited. Edit:

No S-VHS recorder is in the Luminanzauflösung linearly up to 5 MHz. In practice, I can on an S-VHS Recording few structures imagine so detailed and complex that they are the boundaries of the DV data reduction show. As you would probably already have a Beta SP recording or something similar rankarren.
I respect so synonymous to quality - but you can do exaggerate ...
Also look at diese Edit: Zitat aus der englischen Wikipedia: "Later JVC introduced the new format called Super VHS which extended the bandwidth to over 5 megahertz, yielding 420 lines horizontally. (For comparison DVD is 500 lines.) The chroma resolution remained the same s.approximately 0.4 megahertz bandwidth or 30 lines horizontally, s.was common standards across from analog tape to UMATIC ED Betamax to VHS. " This is synonymous to PAL to.

Bandwidth and scanning of the same two pair of boots ... and even with VHS you can see the influence of 4:2:0 Farbsamplings significantly (at s.deutlichsten red surfaces).
Even at Digital Betacam 4:2:2 looks closely at one sampling artifacts in Comparison to the 4:4:4 source material ...

Thanks for the replies: In summary, I have understood it. The S-VHS signal does not suffer much when it comes to DV format, is digitized. Crucial is the MPEG-2 encoder for creating the DVD. Since the editing program is no significant deterioration causes rather play a role codecs used.
Does the lossless or Canopus HQ codec synonymous in other software, except for Edius?
Thank you!

I would sign it.

Exactly.

I do not know - but if you had to transfer to the PC the lossy (if synonymous for S-VHS in my opinion more than sufficient) DV codec, you should stay with him. Then in other lossless codecs convert disk space costs only and does not work.
