Default Capturing video Hi8 with Edius

Hello,

Just to have an advice or recommendation for the best reliable quality.

Video Format : 8/Hi8 (analogic)

Matériel used to read the cassette : Sony GV-D200E : output available : DV (IEEE) - Y/C - composite

Material used to capture : Edius NX Xpress with bay : inputs : DV (IEEE) - Y/C - composite.

So I have 2 possibilities :

1) Read out analogic Y/C... to NX input Y/C and let Edius create the HQ.avi via the videocard (with TBC included I think).

2) Read out via DV (Ieee) and let the Sony inside converter generate a DV.avi.

The only advantage I see actually is that the Sony generates the DV signal when it only exist.... and if a cassette is not fully recorded... it will stop the capture an not generate an empty files... if the signal comes back it restart automatically the capture....

My worry is just about wich system is giving the best quality result : Sony integrated digitalizer or the NX one...

Thanks for help

Why not test each option and see what looks best on your system?

Of course, I have done... but I don't see spectacular or sensitive difference...

To do the test, do I need a 8 or Hi8 that will provoke a visible difference ? Must it be a wonderfull genuine video take... or a very bad one that will push the digitalisations systems in their entrenchments.

Wich tool in Edius should I use to amplify the difference ?

My question was also to search for somebody having more higher level and acurate material I have, and having already done this analyse

Thanks to have follow

Y/C and DV (IEEE1394) are about the same quality so no, you should not see much difference in them.

Use whatever works better for your workflow.

Over the years of dubbing tons of Hi8 to the computer for editing, I've always found the DV (IEEE1394) has better stability that Y/C as far as time-base correcting. But I agree - if you have a TB Corrector already installed, then the transferred quality should look pretty much the same. I'm unfamiliar with the Sony200, but if it has a good Analog-to-digital processor, then I would prefer the DV 1394 output for your transfers.

Just my opinion, and good luck.

DV has adequate bandwidth and S/N to exceed the potential of 8mm and Hi8. However, the main problem with 8mm/Hi8 to DV conversion is going to be the amount of noise in the original video on tape. Noise eats bits and can degrade the overall quality of the video captured to a lossy digital format. This is a concern especially if you plan to do any serious video correction/restoration where artifacts of lossy formats are compounded. (Same applies to other analog formats such as VHS/S-VHS).

Ingesting via IEEE1394 (Firewire) is convenient, and works well enough for many uses/users. Capturing the s-video output to a lossless format for restoration and editing before recompressing/coding to a distribution format may give better end results but will take more effort. (An external TBC may be necessary in the s-video stream.) In any case avoid capturing from composite video.

In some cases tape read errors cause problems with reliable IEEE1394 capture. Internal error correction in the player may make capture via s-video work better for these tapes.

If the simpler workflow gives you (and any paying clients) the results you are seeking that is what matters.

The GV-D200 has worked well for me.

FWIW: http://www.digitalfaq.com/forum/
is a site focused largely on capture and restoration of video from consumer analog tape formats. The folks there are somewhat obsessive about quality, and have clear opinions on the tools and techniques for doing this.

With my GVD200, I capture Video8 and Hi8 with Y/C (S-Video), and Digital8 with firewire, using either NX or SP hardware.

My opinion is that S-Video is better for analog tapes with this unit.

I have been using "DAZZLE" for years to capture VHS, VHSC, 8mm and Super 8. It works great with a USB connection and software that comes with it. After capturing I bring it into Edius and do any color correction necessary and add filters where appropriate then burn to DVD or BluRay.

First, thank you to you all for your advice.

So : Y/C capture seems beter... but it's beter to have a TBC in between... Did the Edius NX xpress card not have a bild-in one ?

I will take decision depending the average quality... and taking into the advice of dpalomaki... wich is crossing my one... Noise is "gourmand" of bites and need less compression during capture. In this case of lower quality I have to use analogic output (as for VHS) with HQ codec...

Thanks again
