How to Fix a Broken Flip HD Video Camera

July 7th, 2010

stuck on logo screenI like Flip video cameras, they are simple, cheap and pretty good quality for what they are!

However they don’t have a reset button, and I have a broken one! It’s stuck on the ‘Flip Video Press for Setup’ screen – which is the first screen you get when you turn it on.

The model I have is the Flip Ultra HD 8Gb, model: U2120B, I suspect these steps would work for other cameras in the range (that don’t have a reset button!)

Here are the steps I took, with the help of Cisco support to resolve this…

VJing @Church with GrandVJ and Ohm64

March 27th, 2010

Just a quick post, we had youth worship event last night, about 180 kids, and I mixed visuals, projected on the front wall with GrandVJ and the Ohm64 controller…

I’ll post again later on with more info on how I got on with the software and hardware – but overall it was very good, having 8 channels of video to mix with is great, and the ease of use makes selecting videos quick… during one song I did have 7 layers of video in use at the same time!

Video Mixing Software and Hardware

March 12th, 2010

I have a collection of video loops, backgrounds, footage etc, and I like to mix/blend them during worship events, as “Worship VJ”.

I started mixing VHS tapes (eg the original Images for Worship VHS tapes from onbd.org), with a Panasonic MX50 mixer connected to a couple VHS players. This was great with lyrics keyed in over the top…. I started doing this about 12 years or so ago…

Now I have a growing collection of video files and have been looking for the best way to locate, mix and control video mixing of these files – mpgs, movs etc…

I have recently been using 2 laptops with their SVIDEO output connected to an Edirol video mixer, and then connect the output of the edirol to a projector.

However, I’ve been looking for a better solution, and I’ve decided on this:

Software Mixer: Arkaos Grand VJ

Arkaos GrandVJ

MIDI Controller: Livid Instruments Ohm64

Ohm64

They are currently on order, but the idea is, that the software can mix 8 channels of videos, and apply effects etc and more, and using the MIDI controller will make make the physical mixing/settings etc quick and easy…

I’ll post back with how it goes, I have an event on March 28 at which I’ll be using this…

Radio Microphones – Legal and Usable Frequencies

October 25th, 2009

wave 150x150 Radio Microphones   Legal and Usable Frequencies
Here in the UK, we need to be careful about what frequencies we set out radio microphone receivers/transmitters. Even if your radio mic set has 1,400  available frequencies only a few are usable legally without a license. Hopefully this page covers the basics and give some practical advise in using radio microphones.

Recover a Clicking Hard Disk Drive (In the Freezer)

September 10th, 2009


(Again, not really video related, but if you have videos or music on a hard disk that is broken, then I suppose this would be relevent!)

A friend of mine has a laptop that won’t boot windows… he took it to a local computer shop and they said they couldn’t fix it or recover the files… This is how I helped him, with the aid of my freezer!

Reducing Feedback in a PA System

September 4th, 2009

Want to know how to reduce feedback? How to minimise Feedback? How to set up microphones and speakers so as to reduce feedback? – This page will give you some helpful ideas and tips to make things sound nice.

music_bar - Feedback ArticlwWhat is Feedback?

Lots of ways to help you reduce audio feedback in your PA system

Feedback is the screeching/squealing/hooting sound heard when there is an accidental loop in the PA system. That is when the sound from a microphone is amplified and fed to the speakers and then picked up again by the microphone, this sound then carries on round and round resulting in the nasty noise. The feedback frequency depends on a number of factors such as: the resonant frequency of the room, distance of microphone and speakers, frequency response of the microphone, characteristics of musical instruments.

To reduce or eliminate feedback this loop needs to be broken, here are a few ways of doing that. » Read more: Reducing Feedback in a PA System
