Video mixer questions

Hi!

I don’t have any experience with video mixers and I was hoping if I get one I would be able to mix my television’s output with a live video camera output with that camera focused on the television screen. Would I encounter any sync issues with this or could I go as far as to get a cheap / basic mixer to accomplish this without any issues?

Is there anything else I should consider seeing as this mixer will be used with my LZX and BPMC gear?

Thanks!!!

Some mixers have a built in TBC (like the edirol v4/v8), and if so it will be fine. otherwise you need to have a camera with genlock or some way of synchronizing the inputs.

Thanks Transistorcat, looks like I need to get myself a mixer with TBC, cheers!

In case you haven’t searched, there are several other threads about mixers:

Thanks in advance for any suggestions … > I’m looking for a budget video mixer, and thought the Panasonic MX-50 might be a good place to start. Problem is, the only MX-50 mixers I can find online are listed for ‘parts’. > Any ideas on where I could find a used MX-50 mixer ? or something equivalent? > I’m a n00b, so want to buy good quality but don’t want to spend crazy either. > Regards, > JayB.>

the old panasonc video mixers are nice but bulky and possibly noisy. i like the edirol mixers since they are small and packed with features

Has anyone ever used both the Edirol V4 and the V8? I have a well used V4 & like it but just saw a V8 come up on offer for a cheap price & apparently with little use. I’m tempted.

I have both and use them in different situations. The extra four input channels on the V8 are very handy, as are the S-video and VGA ports. I prefer the V8 blackout slider over the V4 blackout knob. On the other hand, the V4 is smaller, lighter, and creates more classic noisy feedback blooms.

The differences that make an upgrade to a V8 100% worth it for me:

Very usable built-in feedback effects (one of which is actually a framebuffer delay)
One channel of VGA in, for easy computer input
Loop thru of all the inputs

More discussion of V8 here, incl. video examples of feedback effects.

Thanks @Dewb & @sean for the info & the link

I wasn’t aware of the feedback effect or of the VGA in.

Hey :))

Thx for these details ! Does anyone know if the edirol V-440-HD also include a TBC that worth it ?

@fgnermood

I used the V440 as the heart of a system for several years and never had sync issues.

I have since moved on and have one to sell if you need one.

my biggest hurdle with sync was always VHS input and back when I was using the V440 as the heart I had the VHS playback deck coming into a V4 which came into the SD side of the V440.

however I also used to capture various VHS tapes I found via VHS deck > V440 > BMD hyper intensity shuttle > computer so I know it works.

just looking at the block diagram now

it looks like each of the 4 busses has a frame synchronizer
