How to Make a Time-Lapse Video With Your Digital Video Camera

Getting the most out of your digital video camera can mean being able to create some really cool stuff. You just have to step outside the manual a bit and find the cool things you can do with your digital video camera and your editing software.

We have all seen them in a movie or a TV show, those very cool shots where they speed up time and capture a long segment of time and condense it into a very short amount of video. An example is many of the TV news stations nowadays have a camera that captures the day's weather and then they process it down to a 20 second clip to show the clouds and weather racing by on screen.

Well this technique is not just a tool in the hands of the movie makers or the big TV stations. You can do this with your digital video camera gear too. I will go into two ways that you can accomplish this effect and get some cool results for your next video project. This one is worth playing around with in order to find the right settings to get the most dramatic effect.

Technique number one is to use the camera itself to do the time lapse recording for you. Almost all digital video cameras have the ability to do an interval recording. What this means in a nutshell is that you tell the camera how long you want to record for and how long in between recordings and it will go on autopilot for you for as long as the battery lasts or the tape runs out. This is what those cameras at the convenience store do, they record a few seconds of motion every 30-60 seconds giving the overall view of the traffic in the store over time.

Now if you want to capture some time lapse in your digital video camera you will need to get into your cameras menu and find Interval Recording (or in my case Int Rec, as I use a Sony PD 150 for my camera) When you select this option you will decide how long of an interval between shots you want and how long to record each time. If you are trying to capture something that takes a long time to occur and in which not much happens quickly you will want to set the interval at around a minute and the record time as short as possible on your camera. An example would be if you wanted to record a day in the life of a flower or the clouds rolling by in the sky. Suppose however that you want to capture an event that has lots of action and occurs over a much shorter time frame. Then you would want to shorten the interval between recordings and increase the time of each recording. So in this case you might record every 15-30 seconds and record up to 2-3 seconds of video each time.

I used this technique to capture an afternoon of work being done by a team of carpenters on my house remodeling project. The result was a flurry of activity as workers raced hither and yon nailing boards, carrying equipment and building walls. I have added it to my photo collection of the project. (Hey I had to live through the project so I might as well have a great record of it for posterity!)

Now suppose you have one of the great software video editing packages on your computer to work with your digital video camera. Now you can do it in post as they say in the business. You can record any length of video you want (subject to the limitations of your tape length) and then import it into your editing program.

Sidebar:

I use Adobe Premiere Pro for my editing jobs, but I have also used Avid DV Express, Final Cut Pro, and others in the non linear editing world. These are all great programs and are very powerful products that can create some very professional looking videos. You don't have to have these products to create your own videos but if you are serious about digital video editing it might be a good idea to take a look at these options.

I digitize my raw video of the scene I am doing time lapse on into my computer (big hard drive, video eats up GB's of space) and then import the clip into my time line. From the timeline you can then select the clip with a right click. From there you will be given a menu with options depending on the software you use. Select the option that says "duration", "speed" or something similar. Change the speed of the clip so that time will speed up considerably. If you have an hour of video in the clip and want to shorten it to 2 -5 minutes then you need to increase the speed of the clip to 3 or 4 thousand percent of normal. This will require your software to render the clip at the higher speed and may take some time top process depending on the speed of your computer.

Once you have rendered the video clip at the new speed you will want to play it to see if the movie flows evenly or if you will want to readjust the speed setting to make it better. Sometimes you may want to shorten your raw video and adjust the speed down somewhat in order to get a smooth flow of action. Once you have rendered the clip at the new speed you can now cut and splice it as you see fit with the speeded up action intact. There are some things you will record that might only need a slight speed change, take for instance some digital video of your kids playing sports. Double or triple the speed of the clip and show it to them and you might have them rolling on the floor.

You can also use these techniques to capture the growth of a flower or plant over the course of days or weeks. Simply set you camera in exactly the same place at the same time each day and record an interval that works each day fro however long you want to document. May be you get the seedling just breaking soil and follow it all the way through turning into a full grown plant.

Another interesting idea is to capture the path of the moon across the night sky. Set up your camera on a tripod in a spot that can see the path of the moon for several hours. Set the camera to interval record and put the moon on one side of the frame so that it will pass across the frame as the night passes. This one may require some testing in order to get the exposure and framing right as well as the right interval to record at. Most likely you would want to set the interval as long as you can and the record time as short as you can but do a test run first to see what works.

Best Practices of CCTV - Implementing Successful Video Security Systems

This CCTV Buyers Guide provides a comprehensive overview of deploying a successful video surveillance camera system in your business or residence. This guide contains information to help in the design of your video surveillance system, select the products that best fit your CCTV system requirements, and help make key installation decisions that will save you time and money.The information was derived from deploying 100's of CCTV systems and gathered from CCTV call centers who answer questions from commercial and residential customers. This guide combines the data from past CTV projects and gives the reader a head-start in the successful CCTV project

There are many details to consider when specifying the correct CCTV Camera System. Professional Video Surveillance is not a cheap endeavor and a budget should be outlined and the best possible system should be considered. This guide will help the novice CCTV buyer in reviewing camera and recording system for their CCTV and Video surveillance requirements.

The first task in a successful CCTV project is to outline the key CCTV objectives.

o How many cameras are required?

o What are the key FoV (Field of View(s))?

o What are the recording requirements?

o What are the lighting conditions of each camera location?

o Where do I need live video monitoring or a second video monitor?

o How long do you need to retain the video files?

Cameras There are specific cameras that need to be selected based on the FoV, lighting conditions, and the mounting location of the camera. There is no such thing as a one-size fits all in the successful CCTV project. It is important to note each camera location and select the camera best suited for that location.

Answer these questions:

o Indoor or Outdoor?

o Lighting conditions (during day and night)?

o Mounting locations?

Indoor Dome Camera

The indoor dome camera is used in 90% of general indoor applications. It comes in a variety of configurations including standard color, Day/Night, and Infrared versions. It can be mounted on a horizontal or vertical surface but is typically ceiling mounted. Lens options on dome camera may restrict their use in certain applications such as requiring more than a 20mm video lens. Dome cameras are a primary choice in indoor camera locations.

Box Camera

A box camera is a standard camera that can be mounted alone or in an enclosure. The box camera uses a separate lens that screws on to the front surface and provides flexibility for different FoV requirements and is sold without a lens. An auto-iris lens will have a small cable that connects to the camera for iris control in various lighting conditions.

Outdoor Dome Cameras

Outdoor Dome Cameras are typically hard shell vandal-roof casings that offer the same versatility in a variety of lens options. Day/Night outdoor dome cameras are common in applications that have entry and exit points with limited lighting during the night.

Day/Night Camera

The Day/Night camera is the best choice for low-light conditions. The cameras are standard color during daylight conditions, the Day/Night camera switches either digitally of mechanically to a low-lux B/W mode.

Infrared Camera

During No-Light conditions, Infrared cameras provide infrared illumination of the FoF allowing monitoring of areas with no light available. Te IR LEDs are automatically illuminated and the camera switched to the B/W low-lux mode offering camera views in total darkness.

PTZ Camera

Pan-Tilt-Zoom camera offer the ability to view in all directions and optically zoom in as required. PTZ cameras also include standard color, Day/Night modes, and a few IR PTZ cameras have been introduced recently. The CCTV operator can set the PTZ cameras to automatically rotate to different FoVs. Options include Auto-tracking applications that dynamically track objects in defined areas.

About the Camera technology

Sony CCDs are the predominate video element in security cameras today. Sony makes few cameras, but they own the CCD market. Do not think that Sony makes the camera touted as " Sony 1/3" Super HAD Camera" as many vendors advertise their cameras. The camera has a Sony CCD, however the camera is not from Sony and could be almost any brand camera out there. Important factors of lens quality, vari-focal and auto-iris ability, quality of camera housing or enclosure, and lens optics are the difference in a professional CCTV camera.

Facts about Cameras:

o If you buy an camera, you will get an view.

o 480 TVL should be a minimum requirement in any professional CCTV project.

o Location of the camera and the correct lens are keys to quality video capture

o Cameras love light and thieves hate the light! Add lighting wherever possible

Camera Enclosure

Box cameras can be mounted in a variety of enclosures. Outdoor enclosures in cold climates should include a heater/blower that keeps frost and condensation from forming on the lens and camera. Heater/Blower are commonly 24VAC and should be considered when selecting the CCTV power supply system.

Camera Location

Camera mounting location is critical to the success of the CCTV project. Cameras should be mounted as close possible to the field of view required, and the closer the camera to the subject the better the identification of the subject will be. Proper lens selection relative to the camera location and the FoV required is essential to a quality picture.

Digital Video Recorders

DVRs are an important part of any successful CCTV project. Video resolution is getting larger, recording speeds are getting faster, and video data compression is reducing the video data file size. TeraByte storage capacity is becoming common in many CCTV applications. Network or remote monitoring of CCTV video is standard in all professional DVRs on the market in 2007 and video distribution across LANs, WANs, and the Web have given the DVR a new market outside of video security known as Business Systems Monitoring that allows management to monitor specified key business areas 24 hours a day. No longer just a security video recorder, the DVR has become a business tool for management with remote monitoring applications.

In order to choose the correct DVR for any application, the following questions need to be answered.

o How many channels (cameras)?

o What speed of recording is required?

o How long to retain video files (Hard Drive Size)?

o What features are important to the application?

o Where will DVR system be located?

o Remote monitoring requirements?

In choosing the right DVR for your CCTV application, ensure that you are determining the quantity of cameras needed now and in the next 24 months. DVRs come in 4, 8, 9, and 16 channel increments and this selection is critical because adding cameras above the DVR channels available will require an additional DVR, not just additional channels. DVR systems in large installations are segmented into 16 channels units and are monitored and managed through a Central Management System.

The speed of recording is critical to many CCTV applications. 30 fps (frames per second) is considered real-time video, therefore to obtain 30 fps for the application, 480 fps for 16 channels and 240fps for 8 channels is required. Many CCTV applications will provide real-time (30 fps) live viewing of video channels and 7-15 fps for recorded files. It is acceptable to have 7-15 fps for recorded files in many applications, but technology in DVR systems has pushed real-time video for the masses and 30 fps recording will soon be the standard recording rates across all channels as available today.

Storage of vide files is much easier and cost effective in 2007 than ever before. DVR storage at the TeraByte level is common and drives have become faster and more reliable. Retention of video data files can be managed by corporate IT departments as any business critical data and network drive archiving is common. All of the top DVR systems have USB ports for external storage devices and LAN-based video servers are common. A critical component of any DVR system is the ability to access the video files. The software provided by DVR manufacturers is proprietary to the DVR unit and the ability to retrieve files chronologically or based on certain security events is vital to the DVR product.

PC-Based vs. Standalone DVRs

Standalone DVR systems were the majority of video recorders sold in the marketplace up until 2006. Computer-based DVRs have become increasingly popular due to the cost and features provide in the latest generation of DVR cards on the market in 2007. The Windows XP PC computer is providing the reliability and performance in today's DVR systems that are required for mission critical video security systems. The open architecture of PC-based DVR systems allow easy integration into corporate LANs and technology upgrades are at a component level. Software upgrades and hard drive storage additions are far less costly that proprietary DVR systems. Standalone DVRs are imbedded recording systems usually operating under Linux OS. The standalone DVRs are widely used in retail security sites and provide reliable video recording for 4-16 channels. Most DVRs on the market offer network remote access and CD R/W archiving.Computer-based DVR systems are reliable, fast, and have many advanced applications not found on standalone systems.

Video compression

MPEG4 and H.264 are the video compression of choice in 2007. In summary, MPEG4 is good and H.264 is better. The key to video compression is the resolution and the size of the video. High resolution video files are monster size files and video compression for storage and streaming is critical to any video application. Major advancements in video compression will be seen in 2007 and H.264 will be the codec of choice for DVR manufacturers.

H.264

This uses the latest innovations in video compression technology to provide high resolution video quality from the smallest amount of video data required. Smaller files will save bandwidth and storage costs over previous generations of video codecs. H.264 delivers the same quality as MPEG-2 at a third to half the data rate and up to four times the frame size of MPEG-4 Part 2 at the same data rate. H.264 is used in the latest video devices for High Definition video devices, BluRay DVDs and should be considered for any professional CCTV project.

Network Access and Remote Viewing

Network access is the ability to remotely monitor a video server across the LAN, WAN, or internet. A very important application for any DVR system is the ability to monitor live and access to recordings through remote access. Most DVRs today have a LAN RJ45 connection that allows the Video Recorder to connect to the LAN just like any other PC in the office.

Advanced DVR Features

Many CCTV systems are releasing advanced security and specialty software for security enhancements. These include:

o Object counting

o POS Integration

o PTZ Auto-Tracking

o Face Recognition

o Access Control Integration

CCTV Cabling and System Layout

DVR Location In choosing the optimal location for the DVR system, consider the access of the area for centralized control and security of the area. The DVR is the heart of the CCTV system and should be protected as necessary to ensure it is safe from theft or damage. If the security breach includes theft of the DVR component, all evidence is carried off under the arm of the thief. And the thieves know this, so ensure that the DVR system is in a lock-box or an appropriate secure area.

Camera Power Supply

Each professional camera requires either 12VDC or 24VAC. Both power options are acceptable and some CCTV installations will require both. Central Power Supplies are available in 4,8,16 and more channels.

Cable Options

Traditional video cable is RG59 coax cable. Siamese dual cable is commonly used that provides RG59u coax together with a pair of 18 gauge wire for the camera power requirements. The dual cable allows single cable runs to each camera for both video and power.

Cat-5 Options

UTP (twisted pair) cabling is becoming more popular with Cat-5e/Cat-6 cabling used in networks. CAT cabling is lighter and less expensive than coax cabling and requires balun connectors to match the impedance of the video signal. Coax and UTP connections up to1000' feet are acceptable. A balun is used to match the impedance on Cat-5 connections on the DVR and camera connections.
