Edius I/O cards for Edius X

[dpalomaki]

I guess for me it boils down to:

For SD capture from s-video and composite sources only, (ignoring SDI capture and resolutions beyond HD) is there any image quality advantage in the Analog-to-SDI and and Decklink Mini Recorder option over the (not 4K) Intensity Pro? (Well, I guess the IP does have analog output option as well.)

(I haven't considered it yet, but perhaps duplex operartion with backgroud recording while editing/previewing to the monitor?)

there is a huge advantage doing it my way, because the BM analog to SDI mini converter produces accurate blacks and whites whereas the Intensity Pro clips the blacks during capture and these lost blacks (dark areas) can't be recovered

Thanks,
Is the clipped black unique to PAL, or an issue with 7.5 IRE NTSC as well?
(I know the IP 4K has problematic SD blacks.)

as far as I know the issue happens in Pal and NTSC and can't be fixed and will never be fixed because these cards will be phased out, I spoke to the horse's mouth

Does Edius X support the BMD Mini Recorder 4K. or does one need to use another capture program such as BM's Media Express softeare? (I note thqt Edius is listed for Mini-Monitor 4K but not for Mini-Recorder.4k)

I am using the Mini Recorder 4k and the Mini Monitor 4k, both work fin in X and in 9

Trying the Analog to SDI. Is it my imagination, or does the device clamp blacks (IRE 0 or 7.5) to digital 16, and similarly limit whites to IRE 100 (digital 235).?

I believe that the the Intensity Pro would allow blacks below digital 16 (IRE 7.5 for NTSC) and whites above 235 (IRE 100). If that is the case one must be sure to monitor sources such as tapes carefully not to lose shadow or highlight detail or high from funky sources.

are you referring to this unit? it works perfect for me, no clipping of anything

Both the BMD Intensity Pro (not 4K) and Analog to SDI Mini-Converter set for 7.5 IRE.
Video gains set to 0 dB on both the IP and A-SDI
Source is a Video generator sending SMPTE bars and a step from 0 IRE to 105 IRE vi s-video
Capture is E9.5 to GV HQ.

As can be seen in the attached photos the IP sees the nominal 5 E black (as -5) and the 105 white.
The A-SDI clamps the black at the 7.5 IRE and limits whites to the 100 IRE levels.

I see this as an issue when using poorly disciplined sources such as VHS. Looks like a proc amp is very much in order with A-SDI.

all my VHS players are connected to a TBC or have one built in and I set levels correctly before capture with the controls on the TBC while viewing waveform

[dpalomaki]

Thanks. I suspected that might be the case.

Anton. If you had to buy another TBC , what option is available. Just can't buy them anymore

Don't you have the Tarranex?

You may find used TBCs maybe on ebay etc

FWIW: http://www.digitalfaq.com/forum/ includes threads on TBC's recommended, and not recommended, for consumer grade video sources such as VHS and Video8. The issue there is that professional grade TBC's often have difficulty with the sloppy signals output by consumer grade sources such as VHS tapes. They also discuss that some variants (e.g., internal revision numbers) of the same make/model are better than others. They also stress that any video gear bought from ebay comes with risk because many private sellers are clueless about video gear. Be aware many of the people at that site are very into legacy analog video capture and restoration so what may be "good enough" to many folks will be unacceptable to them.

There is a market for good used TBCs but the prices are not cheap. For a fixed duration/scope projects an approach is to buy a decent one, use it, and then resell it to recover most if not all one's cost.,

Teranex's do not have TBC in built and they need one as much as any I/O
