Radios-TV on YouTube 2In case you’ve not yet found it, the Radios-TV blog and Vrat forum now has a YouTube channel. For many years, my blogs and forum threads have always run along the lines of an over the shoulder repair. Documenting each stage with text and photos as an item was brought back to working order. Well now, after much persuasion, I’m moving into the 21st century and joined the ranks of YouTube.

What Else?

Well Radios-TV/Vrat members who are working on a project or fault, might find it useful to share the results of their work or seek assistance with a tricky fault, via a video. Some members may not have, or indeed have no desire to set up a channel of their own to present these videos. Most members however do have a smartphone or camera, so why not take advantage and make use this blogs & forums YouTube channel?

If you wish to make use of this service, then you can upload your video via the “member’s upload service”. The system will automatically notify me that a video has been uploaded and by whom. I will then transfer and make your video available via the forum’s YouTube channel, then e-mail you the video link, so you can embed it in a forum post.

Thus far two members (Brian R & PYE625) has used the service to demo their B&W TV faults and of course many of you will have seen the videos I have posted on the Thorn 9600 and recently the Philips N1500 and N1700 video repairs.

I think this feature will be of great help to members seeking help with a fault or wishing to show off a particular repair or feature, at the same time adding a new dimension to aid in remote fault diagnosis.

Please help the channel to grow by subscribing and perhaps considering using the service as detailed here, when you next tackle a repair. There’s a shortcut to the channel via the hot link bubbles on the right-hand side of the forum.

All my videos to date have been filmed in HD 1920x1080p on my mobile phone, not ideal. I’ve just upgraded myself from that setup to an JVC GC PX100 HD Camcorder.

JVC GC-PX100 – Features

The 1/2.3-inch back-illuminated CMOS is large for a camcorder, but also means this is no DSLR beater. The sensor does sport 12.8Mpixels, however, and can capture stills at up to 4,000 x 3,000 pixels, so this certainly has the potential to negate your need to bring a digital camera on holiday as well. There are lots of shooting format options, too, with MP4, AVCHD, MOV and iFrame all available.Radios-TV on YouTube 3

The MOV format provides the highest quality, offering a 40Mbits/sec data rate for Full HD at 50 progressive frames per second, with 4Mbits/sec of this used by the LPCM audio. You can grab the same resolution and frame rate in MP4 format at 36Mbits/sec, while AVHD only offers this at 28Mbits/sec, which is the standard for AVCHD 2.0. The iFrame option is 720p at 25 frames per second and a healthy 36Mbits/sec.Radios-TV on YouTube 4

This is a bewildering range of formats, but at least they give you the flexibility to match whatever your chosen editing software or online video sharing service prefers. With footage recorded to a single SDXC-compatible memory card slot, a 32GB module will give you around 107 minutes of recording at the top MOV quality setting.

Despite the large sensor, the GC-PX100 still offers a pretty healthy 10x optical zoom. With plenty of extra sensor pixels available over and above those required for HD video, there is also a 19x dynamic zoom available too, although this is only enabled in 720p mode, with just 14x on offer at 1080p resolutions.

Not surprisingly, image stabilisation is optical too, with an extra advanced mode available on top of this. There are in fact three image stabilisation options, including AIS, EIS / OIS and Enhanced AIS.

The JVC GC-PX100 is even more expensive than its predecessor, coming in close to £1,000, which is increasingly unusual for consumer-grade camcorders these days. However, it does exude quality, with a host of helpful extras included in the box, and every enthusiast feature you could want.

Although the PX100 has a 460Kpixel 3in LCD, there is also a detachable EVF included in the box. This connects just above the LCD, with a button on the side to switch between the two, and a dioptre adjustment on the other side. There is also a glare shield and cover you can clip onto the back of the LCD. We found the fit a little loose, however. The LCD itself folds out, so you can angle it facing up or down as needed.

  • 1/2.3-inch CMOS with 12.8Mpixels
  • 10x optical zoom; 19x/14x Advanced Zoom (720p/1080p resolution)
  • Optical Image Stabilisation and Advanced Image Stabiliser
  • Variable slow motion and time lapse recording
  • AVCHD 2.0, MP4 recording at up to 36Mbits/sec, MOV up to 40Mbits/sec

JVC GC-PX100 – Wi-Fi Features
With so many other features, the inclusion of JVC’s wireless capabilities aren’t a headline act for the JVC GC-PX100. It has the ability to connect to an existing WLAN or function as a standalone access point, albeit without internet access.

You can access camera functions via the Everio Sync app for Android, iPhone, iPad and iPod touch. Another app has just become available, too, called JVC CAM Coach. This lets you watch and annotate videos from the camcorder, although it is currently only available for iPads running iOS 6 or higher.

Canon EOS M10

This is my overhead camera, The EOS M10 is compact and nicely built. It measures just 2.6 by 4.3 by 1.4 inches (HWD), weighs 10.6 ounces without a lens, and can be had in a black, gray, or silver finish. It’s a little smaller than some other cameras in this class. The M10 doesn’t have a front grip, but it does have a rear thumb rest.

4K Camera

When I want to shoot in 4K, I use my Samsung S10-Lite, the quality and image stabilisation is superb.

Shooting videos from television screens tends to generate undesirable aliasing effects if your video camera/camcorder doesn’t have genlock. In the past I have used a Sony TRV22 that offers a digital slow shutter mode and this does eliminate aliasing bars. The only slight disadvantage being a slight smearing of moving objects.

Recently I thought I would look for a replacement for the TRV22 that offered higher definition and I bought a Panasonic TZ100 that is specified with higher definition and slow shutter modes. Unfortunately there appears to be a subtle difference between the TRV22 slow shutter and that in the TZ100 such that no matter how slow I set the TZ100 shutter I still get small aliasing bars. Thinking that I might get around the problem if I returned to Sony I then bought a Sony HDR HC3E only to find that it too shows aliasing bars regardless of shutter speed.

I can’t understand how the slow shutter of the TRV22 gives complete absence of aliasing bars but the newer machines do not. I wonder if anyone has found a high definition camera that can completely eliminate aliasing effects without the need for genlock?

Since writing the above on aliasing I have had two interesting replies. One from Phillip (Catkins) on the Stenning forum where he linked to a video he had recently taken from the screen of his Murphy A56V
It looks a little flickery but is free from the rolling bars. It was taken using a Canon PowerShot SX720 HS.
The other was from merlinmaxwell on the same forum, saying: “Most new digital cameras will “auto sync” to an “AC” scene, all my Panasonic Micro 4/3rd’s jobs do it, you can see them syncing in the (electronic) viewfinder. Rather impressive.”

Would love your thoughts, please comment.x
