JVC GY HD250 sdi out to blackmagic video assist HD to record 720p?

Yes, that's a limitation of the Red One. But in my opinion, the Red Raw is 90% of the reason to use that camera. Please do keep us posted on whether you are successful with the JVC!

FYI, I think you can get it to work with the HVX200. It requires a component to HDMI adapter box ($20 on Amazon, but it requires its own power source). However, the HVX200 has a much easier and cleaner solution in P2 cards.

I got it to work with an XH-A1 though, which is only tape-based. I think that the signal was uncompressed this way and the image quality was actually improved:


Big tangle of wires to get it to work, though. If I owned that camera again, I would probably just record to tape.

Yep, I invested in P2 cards for the HVX and that’s a perfect tapeless solution. Big, heavy, robust cards. I’d say you could drive a truck over those cards and they’d still work! Nice results there with the Canon XH-A1!
 
Here's a Sony TRV67 from 1999 (the camera I mentioned on the last page).

I'm actually in the process of filming some stuff on some brand new Hi8 tapes I got from eBay, but thought it would be cool to show it here working with the VA.

Likely via a similar setup to the one above where the box is upscaling the video signal.

This was the first camera I ever used and owned in 9th grade (that one in the picture).


Excellent! How satisfying to be able to get your first ever camcorder back in action like that! If I still had my first cam, the Canon XM2, I presume I could use the component out to record in the same fashion and bypass that dreaded tape deck... Hmmm... Lets tackle the JVC first anyway....
 
And now look what you guys have inspired today! Another old cam (mini dv Panny NV GS17) connecting to BM and upscaled to 1080p!

That's the spirit!

I was looking around last night and found some next level external recording solutions:

An Atomos or BM recorder will surely yield better results, but I like how tidy these builds are. Videos like these explain why old tape-based camcorders have been sky-rocketing in price!

Yes, I’d actually seen that Immersion RC powerplay unit vid before but when I looked to buy one, I couldn't find one in stock anywhere. Don’t see any available now either.
 
I'm trying to get all of my old legacy tapes from VHS on up digitized, an endless process. Last year I acquired a Blackmagic Hyperdeck Studio HD Plus, which unlike my various Atomos recorders has H264 as a record option in addition to ProRes and DNx, which is great for the less critical and longer form tapes, and it accommodates SD as well which is becoming more rare in a solid state recorder. For more portable field recording with one of my old tube SD cameras I use a Blackmagic analog to SDI adaptor and an Atomos Samurai Blade (their last model to intake SD). In theory I could add a Decimator MD-HX to upscale the image for use with any modern recorder.

Excellent. I can see how H264 would make sense for longer form, non critical stuff alright. Thanks for the info.

Hi all,
Anyone know if you can successfully record 720p via the sdi out of the old (very old) JVC GY HD 250 camcorder (actually 251 PAL model) into the basic HD Blackmagic Video Assist 3G 5”? Just using a sdi to mini sdi cable, right? I own the blackmagic and it’s a terrific device for all sorts of uses via hdmi. I just wonder if it could also breathe new life into old cams like the HD250 which have sdi...

Well, I finally got my hands on the JVC today and attached the Blackmagic Video Assist via HD SDI. Here in PAL land, the HDV settings in the camera output to the BM as 720p50 exclusively and the DV settings output as 625i50 exclusively, regardless of what I set it to in camera. Camera doesn’t have to be recording to tape to have it output either, which is a relief. So, results are about what we anticipated. The camera is a beaut tho and first impressions of the image it produces are good.
 
All of the HDV output settings are either 50p or 60p depending on if the camera is set to 25p or 24p.

Maybe check out the SD pull-down setting and see what the BM sees...maybe that's the only way for a 24p output.
 
Check out 'format' in the middle column in post #9. I never used that camera so I'm brainstorming, but the chart I enclosed has 60i with 24p in parentheses which is usually an indicator of some kind of pulldown, I believe.

I think I’ve cycled through all the HDV and DV settings now and I’m not getting 24p output. Here’s a DV setting from the chart, for example:

Yeah, probably not then, I figured it was worth a try.

Cheers, indeed it was. I’ll tinker around more with this gear and if I stumble across 24p output, I’ll post here. Doubtful though. I think this cam & BM will see action for me mainly as a 720p50 Prores machine and I ‘m happy with that. A big machine, that is:

Looks pro. On a related note, I always thought it was funny how normal people even today would still think something that looks like that is really good and expensive (of course it had its time).

Haha. Yes, pro looking and a bit intimidating! I remember bringing a GY HD 200 (same form factor) to shoot a local politician give a speech at some opening years ago. He was expecting some local kid with a handycam, I think, and when I set up, it threw him completely! Not his best speech as a result.

The cam does have pro features that are a joy to use though. Ergonomics, switches for zebras etc, smooth fast zooms with the fujinon lens etc. You can find these cams for a steal now too and, hey, if you go for one with HD SDI out, you can use your BM! Happy days.
 
Looking at that camera brings back a few memories! I made one of the rollout videos for it. Never used one again after that shoot though!

Web video from 2006 was not pretty...

Outstanding, thanks for sharing! Simpler times. From my experience of playing with the cam over the past few days, you certainly weren’t wrong about some of the better features. I have to say that the flip out monitor is actually very good for nailing focus (focus assist is subtle but effective), the fujinon lens is a joy to use in manual mode and completely nails a fast zoom and precise stop with the rocker engaged, colour reproduction is nice and the image is very pleasing. Bit soft and grainy maybe in a 720p kind of way. I still can’t quite figure out a way to toggle through white balance settings beyond the two presets or doing a manual white balance. But man, the cam sits so comfortably on the shoulder, the evf is good, the battery lasts for an eternity, the layout of buttons is logical and accessible, you get two headphone jacks and an hd sdi out. That’s not bad at all for a blast from the past!
 
I felt bad for JVC. They were often one step ahead of everybody--they introduced VHS, for chrissakes, and think of the camcorder from Back to the Future. But they virtually never got any credit. While every other manufacturer was making 1/3" cameras that were less than ideal handheld, the 100/200 series sat long and low on the shoulder. There has never been a "prosumer" camera built that way since (I could be wrong but I can't think of one). The DSLR form factor was pretty much the opposite of this thinking.
