Video feedback - cheap camera options

Post by hewed » Wed Mar 10, 2021 7:51 am

I'd like to get a cheap camera for video feedback work through my Roland V-4ex. I've picked up some general tips from ex zee ex's youtube channel, particularly on using digital cameras and making sure you can override automatic focus, but I'm fumbling with duckduckgo searches for recommendations. I'd rather not make a beginners mistake with my purchase.

Does anyone have any recommendations for good, cheap cameras for this work, or a handy link to good info on this topic?

you can go with several options.

I have used CCD security cameras with good results. make sure you get a lens with it and that it does not have automatic white balance correction.
that level correction is not so great when doing feedback, as it keeps trying to correct the image and by doing so, ruining a stable feedback image.
Get a lens with manual focus . zoom is nice to have, and some control over other features (digital with a menu or analog on the lens)

You can also get a Handycam. make sure it has composite out and enough control over zoom, focus and white balance.

Cool. Good answers. Same question.

I've got a I'd like to buy a camera, but not sure. I ordered a Panasonic WJ-AVE7 mixer to test out. Should be in a few days.

So need something to plug into this.

Help please

The AIDA HD-100A industrial block-camera seems the go-to camera for cost-effective, high-quality 1080p60 video and includes a great feature-set for an industrial camera: 1/3' CMOS sensor, HDMI-out, TRS audio-input, interchangeable-lens mount (CS-mount), etc. Sells for just $280 and comes with a 4mm lens (7x crop-factor = 28mm full-frame equivalent). AIDA makes two additional CS-mount lenses with manual-focus/aperture-control, a wide-zoom and a tele-zoom (however, there are no macro lenses available for CS-mount at this time).

For more, go to BHphotovideo.com and drill-down:
Professional Video → Industrial & Multi-Purpose Cameras → filter under "AIDA Imaging."

To see compatible CS-mount lenses, drill-down:
Professional Video → Lenses & Lens Accessories → Industrial Video Lenses → filter under "CS-mount" or "AIDA Imaging."

Update: While researching an answer to Kent's thread, I stumbled on the Sony HXR-NX100 NXCAM camcorder ($1,498). Its feature-set is nearly identical to the $200 cheaper Sony HXR-MC88 camcorder ($1,298); however, a key difference for video-synthesists in particular is that the NX100 has both an HDMI and a composite-video BNC-output, a pretty rare feature in a modern camcorder.

The NX100 adds another unique feature for a prosumer camcorder: Variable frame-rate from 1fps to 60fps. The MC88 on the other hand boasts a larger 0.43" 2.36-million pixel OLED EVF, while the NX100 is equipped with a smaller 0.24" 1.5-million pixel LCD EVF. Both cameras' flip-out displays are LCD and have the same resolution: 1.5 million pixels. Both cameras have Super16-sized, 1" sensors, relatively large compared with lesser consumer camcorders and the main reason I singled these two models out.

Both units' lenses appear identical: 12x optical-zoom range (29mm to 348mm full-frame equivalent; f/2.8-f4.5 maximum-aperture); though, the NX100 sports a Sony G-series label, while the MX88 wears the more "premium" Zeiss brand (Vario-Sonnar T). Whether there's any actual difference between the two is unknown.

Both models include optical SteadyShot-stabilization, plus dual, full-sized XLR-inputs with available phantom-power; a nice pro-touch. While there are perhaps better values to be had among the many APS-C format (Super35) mirrorless-cameras with interchangeable lenses, these two Sony camcorders pack a ton of features into a pretty affordable package, each well under $2K.

+1 for b/w cctv cameras. I ended up having to buy a few on eBay (not really knowing what to look for) and swapped a lens out from one to another to get what I needed. I think I spent around $150 in the learning process.
