What about tape?
Before 1956, there was no such thing as videotape. That was when Ampex developed the first practical videotape recorder (see photo at right). Before that, television was recorded by focusing a film (movie) camera lens on a TV picture tube displaying a live television program!
Between 1956 and the mid 2000s, videotape was the way we recorded video, first on reels, then in cassettes. Now, it's possible to record video digitally, so the images and sound are saved as a data file, either on a small card or built into the camera.
When people ask me to film something or tape something, I often correct them by saying, "You want me to make a video recording?" That's because "making a video recording" doesn't limit me to any particular recording medium.
But I didn't include this page on my web site just for the sake of history or semantics! There is a practical reason. When video was recorded on cassettes, I could just take the finished tape out of the recorder or camcorder and hand it to you, pack up my equipment, and go home.
Now, with digital recording, things are a little different. Once the recording is made, it's a digital file inside the camera. I can't just take it out and give it to you.
This is a photo of the first practical videotape recorder, the Ampex VR-1000. The prototypes of this machine were first demonstrated for customers in 1956. The reels of tape were placed on spindles on top of the console at the right. Although the transistor had already been invented in 1948, all the electronics in the VR-1000 were based on vacuum tube technology. What you see here cost $45,000 (in 1956 dollars, equivalent to about $390,000 in 2015!).
In 2007, the iPhone was introduced by Apple. Now smartphones can make much better recordings (in color), and even include the camera itself, which the VR-1000 did not (!), all in the palm of your hand.
I took this photo at the Museum of Broadcast Technology in Woonsocket, Rhode Island, April 2011. See http://www.wmbt.org
Once a recording has been made, typically I take the camera back to my studio, attach it to a computer and upload the digital video files into it. Then, I could just send you the files, but as video files are too large to send as Email attachments, you and I have to decide how I'm going to get them to you.
So, whenever I shoot a video, I have to spend at least some time in my studio, uploading and then sending the files to you.* That means there should be at least something in your budget to cover some studio time for me to do this, in addition to any time I spend making the recording in the first place.
If I'm going to do some editing, such as selecting certain scenes, adding titles, music, still images, and so on, then that's another step in the process. When all the editing is done, I 'render' the file out of the editing software after which I can send it to you.
*(unless you have a SD card reader handy, in which case, we could, conceivably, transfer the files directly into your computer)
Here is a photo of me directing a shot, while using a modern HD digital camera, the Sony HXR-NX5U. It uses 2 solid state SD memory cards, which for the most part, remain in the camera, both while I'm shooting, and while I'm uploading the recorded video into my edit computer.
