In particular video hardware is the physical mechanical interface that stands between the video software and the computer’s operating system.
As a matter of fact your computer is the first piece of video hardware.
Then the next few pieces of hardware are any computer components which enable the computer to create video.
In short any hardware used or involved in video production.
To be sure I use my personal computer to render video.
In the first place the video hardware in my system starts with my motherboard which is an Asus Sabertooth X-58.
Then I have an Intel Golftown Extreme Edition Six Core I7 980 processor.
As well as my memory 24 G Bytes of triple channel DDR3 Ram.
Also my storage is C: Drive SSD Corsair Force 3 SSD ATA D: Drive SATA E: Drive SATA.
Together with a full size Corsair ATA case and Corsair 850 watt power supply.
Moreover the DVD-ROM is LG.
In like manner a LG Flatron E2241 and Viewsonic VG710b video monitors.
In addition the webcams are a 5.0 Million Pixel Rocksoul wc-103webcam and a Logitech C270 720HD Webcam.
Then again I have an ATI Radeon HD 5870 GDDR5 1024 Mbytes Graphics Card.
Certainly my video equipment can easily render 720 P, or 1080P.
Similarly your hardware may be different but most likely you could probably render video in 720P HD.
Indeed 720P is perfect for the video hosting sites like YouTube, Vimeo, Metacafe, Dailymotion, Flickr, Facebook etc.
Video editing and production workstations specifically need their own software.
Dedicated video networked systems with equally specialized individual workstations.
Video hardware includes very specialized professional video graphics cards with attention to video capture, video streaming, etc.
Each workstation equipped in general for processing different aspects of editing inserting special effects.
And or equally rendering video and audio to create and complete professional video productions.
Workstations dedicated for use with highly specialized video graphics software such as the high-end of Adobe.
Moreover Creative Cloud with Photoshop, Lightroom, Premiere Pro, Illustrator, In Design, After Effects, Audition, Dreamweaver, Muse, Flash Professional, Edge Reflow.
In like manner Sony Vegas Pro has special workstations designed to work with it.
Additionally Final Cut Pro, Media Composer, Magix Video Pro, Edius Pro, Lightworks, HitFilm, NewTek all have their networks and workstations.
Indeed Mobile-EDIT Laptop Notebooks for video are video hardware.
Sound is paramount because the video is only as good as its audio.
Therefore the microphone, cabling, mixer, editing deck, integrated or dedicated sound cards are all part of the video hardware.
In fact I use a Turtle Beach wireless headset, a Sennheiser 838 dynamic microphone, and a SESCOM MC-325 lapel condenser microphone.
Furthermore my shure brothers M68A mixer connected to coaxial cable fitted with Shure XLR fittings set the impedance.
Since my Shure weighted microphone stand dampens stray vibrations audio is much cleaner.
In this case my Shure mixer connects to my Peavey PV6 USB Mixer.
Then I feed a Zoom 9030 effects unit into the Peavey EFX Send and EFX Return.
As a result of my Peavey USB mixer a perfect match for my computer is incredible audio quality.
In summary it is more important how you use the hardware than the hardware you use.
In conclusion your videos will only be as good as you regardless of the hardware you use.
Have fun with videography after all isn’t that what it’s all about.
