Fixing Dead Pixels With ffmpeg

Electronic cameras will at some point in their lifetime exhibit dead, or hot, pixels. These take form by a single pixel, or small cluster of pixels, remaining on all the time. Sometimes red, sometimes white, but in every case, but always there. It’s not always easy to spot them, depends on where they are and the colour of the underlying action. You may not even notice them if you are following the on screen action, but as soon as you do, it becomes very distracting and undesirable. Getting rid of these, in most cases, is much easier than you may think. This article describes what I would argue is the simplest way of doing this, particularly as it can be incorporated into the DIT phase of a project. Read More...

Premiere Pro CS6 and transcoding clips

Premiere Pro is very good at working with clips from all over the place all with the same name, and all with many differing codecs. All is well until you need to interwork with other applications such as Davinci Resolve or Final Cut Pro which work best with a single, edit friendly codec. Wouldn’t it be good if Premiere Pro could export each clip in a transcoded form, say ProRes, but it can’t. Wouldn’t it also be good to work with unique media filenames so when media becomes disconnected and asks for where say ‘clip20’ is, and you have 3 different clip20 file, you know exactly what to search for.

Alternative to light stand Sandbags

Putting up light stands or background stands can be a hazardous affair if the centre of gravity is too high, i.e. top heavy. There is nothing worse than stands falling down and destroying equipment or hurting people. This is why you should weight them down, normally with sandbags, but I have another idea. Photography sandbags not only cost quite a bit of money, you still have to source the filling after you’ve bought them, and they are only good for one thing, being a sandbag. If only you could use something else that can also have a function after you’ve used it on your light stands, and chances are, you’ve already got them! Read More...

Custom Fitting Lighting Gels

So I’ve had a roll of lighting gels for years and for some odd reason, I’ve been a bit precious about them. I don’t have many and particularly the colour correction ones are absolutely necessary, so I have never cut them up! I keep them rolled up in a cardboard box, and every time I need to use them I have to take them out, spread them out on the floor, separate them, look for the ones that I need and then put the others back. What a hassle, and not always easy to spread them out. Then once I have the gel in hand it’s a case of C47’s clipping them to the front of the barn doors. Every now and then as the barn doors are altered the gel falls off, it makes the doors harder to operate and overall, a minor pain in the arse. Also, I only have three sheets of each colour correction gel meaning I can only correct three lights. If only there was another way. I don’t know why I didn’t think of this before, but simply cut the gels to fit the lights. Read More...

Virtual World

I have just upgraded my main MacPro 4.1 to an awesome configuration, faster processors, more memory, super charged GPU graphics card, and SSD’s. The only downside of this is that my Snow Leopard installation no longer works. This is an inconvenience because I have a couple of programmes in Snow Leopard that simply are not transferable to modern OS’s. So get with the times I hear people say? Well I sort of agree, but there sometimes just isn’t the functionality that you want, provided, but there are use cases that the IT industry just don’t figure. Such as, in the 80’s I had Cubase running on both Appe IIe and Commodore 64 etc etc, and at that time I was going to be the next best pop musician out there (like all of us!!). Joke in a side, I was very prolific at coming up with ideas, but it’s something that I will one day revisit. The point here is that the ideas are stored in old cubase song formats or even cubase arrangements, which more modern versions of the software don’t support. I don’t want to have to convert them all now, because some will be pointless and it’s time consuming. And anyway, I will no doubt have to do it again as the software moves forward. Read More...
