[Difference Between 1080i And 1080p Camera Cable
Virginie Fayad
My apologies if this has been posted before, couldn't find it in a search. But could anyone tell me the video output resolutions provided by the DMC-FZ28 via the NTSC SD output vs the output from the optional component cable?
actually, playing with this some shows the analog SD signal to a monitor to work well enough for me. I do some fairly difficult coin photography (toned proof coins often in clear plastic holders) where a subtle difference in lighting position can make a big difference so the HD output to a monitor would be nice, but not the end of the world without it.
The Lumix S9 is Panasonic's newest full-frame mirrorless camera. It allows users to create their own custom looks for out-of-camera colors and is the first full-frame Lumix camera aimed squarely at social media content creators.
The Sony a9 III is the world's first full-frame mirrorless camera to feature a global electronic shutter with simultaneous readout. After extensive testing of this 120 fps sports camera, to see what you gain (and, perhaps, lose).
The Fujifilm X100VI is the sixth iteration of Fujifilm's classically-styled large sensor compact. A 40MP X-Trans sensor, in-body stabilization and 6.2K video are the major updates, but do they make the camera better?

I have a Sony HDV 1080i camera and a ton of Mini DV casettes. How should I connect to my computer to get the best quality? I have bought a 'moviesaver 600' by plexgear, which connects A/V out to USB and it works but quality is so so. Is this the best cable/output to use?
Another thing to consider is that nearly all new HDTVs you can buy today are capable of de-interlacing 1080i video signals so they look just like 1080p, which makes it even harder to notice a difference.
These days, 1080p and 1080i are old hat compared to the much more publicized 4K format available with most new HDTVs (often classed as UHD TVs). With 4K resolution, picture clarity is sharper and more colorful than ever. Consumers can also enjoy sitting quite a bit closer to their living room TV without noticing any sort of distortion in the image. This is because 4K TVs display close to four times the number of pixels as a standard 1080p set. Simply put, the more pixels on display, the better the picture quality. Better yet, most UHD sets will also upconvert a standard HD image, making your regular HD sources look closer to actual 4K.
Deciding on which home theater projector to put in your house can come down to one little word: "throw." Long throw, standard throw, short throw, and ultra short throw (UST) are all types of projectors, and they all vary in terms of how much space or distance you need to project a big, beautiful, movie theater-like picture at home.
And while different manufacturers and screen makers vary on the distances needed for each, generally speaking, for a 100-inch image (diagonal), a long- or standard-throw projector could need anywhere from around 8 to 10 feet or more, a short-throw sits around the 3- to 5-foot range, and UST projectors require the least at anywhere between 3 to 20 inches.
When you buy a modern TV, you'll find it will typically have at least two HDMI inputs, and may even have up to four. And you might assume that will be more than enough for your needs! But it's easy to find out that in fact, between your game consoles, streaming devices, and other inputs, you might actually need more HDMI inputs than you have on your TV.
That's not a problem - of course, you can get away with unplugging the HDMI cable from a device that you're not using and swapping it for the device you do want to use - but that's not a very elegant solution, and it can be awkward to clamber around to the back or bottom of your TV to plug things in and out. An easier and smoother solution is to use an HDMI switcher, which is a device designed to mitigate just this issue.
We've previously written that the addition of FaceTime and Continuity Camera to Apple TV 4K is a perfect excuse to have some sort of tripod for your iPhone in the living room. Belkin just took that idea and made it a little easier (and less expensive than our idea).
Enter the appropriately named iPhone Mount with MagSafe for Apple TV 4K. Retailing for just under $50, it's ... well, it's a MagSafe iPhone mount to use in conjunction with video calls on your Apple TV 4K. No cables required. No power needed. Just a simple way to position your iPhone to use when on FaceTime, Zoom, Webex, or the "Sing" feature on Apple Music.

I had a chance for one week (June 2012) to compare the Pentax high definition flexible chip laryngoscope - VNL-1590STi (which I have used for one year) with the Olympus high-definition flexible chip laryngoscope - ENF-VH, which came out in late 2011. The Pentax scope has been available for a longer period of time. My overall impression is at the bottom of this review.
First a few details about my setup since I do not use the proprietary video capture system of either Pentax or Olympus. All of my equipment is set up on a tower with a flatscreen monitor on top. My MacBook Pro laptop sits in front of the stroboscope. Audio equipment is hidden in the back. The video processor is on the lower shelf.
Video capture: I capture endoscopic video images on my laptop computer (MacBook Pro 13inch - OS X 10.6.8) using Final Cut Pro 7.0.3. Consequently I need to ingest video through the FireWire port (IEEE 1394 interface). My video files are captured as .mov files which are easy to view, store or convert to other video formats. The files can easily be viewed on the desktop, in Quicktime, in iMovie, in Final Cut Pro or other video applications.
The Pentax EPKi video processor does conveniently have a DV output which can be plugged directly into an Apple laptop for capturing SD (standard definition) video. However, neither the Pentax nor the Olympus processors output high definition video through FireWire, which is Apples preferred method of ingestion of video. Since I cannot plug my laptop directly into either of the video processors for capturing an HD signal, I need some type of hardware conversion of the video signal and Olympus and Pentax have chosen different output methods.
The Pentax EPKi video processor outputs a computer graphics signal which is 1280x1024 pixels otherwise known as SXGA. I have not been able to find out what the actual resolution is of the chip on the endoscope. In order for me to capture this signal on my Macintosh, I need to convert it to a video format and 720p, which is 1280 x 720 pixels and 59.94 frames per second is the closest approximation to SXGA although I lose some of the vertical lines of resolution. I could upscale it to 1080i which is 1920 x 1080 pixels which generally yields a significantly larger file size depending on compression. In testing this out, I did not find a significant image difference, so I have elected to capture at 720p. The height to width ratio of HD video is 16:9 as compared to a ratio of 4:3 for SD video. My HD videos appear to have a slightly squished vertical appearance as recorded. This can be corrected afterwards in Final Cut Pro or when capturing or exporting still photos in Photoshop.
I use a Gefen DVI to HD-SDI Scaler ((SKU: EXT-DVI-2-HDSDISSL - $879 in 2011 at B&H Photo ) seen in the photo above sitting on top of that Pentax video processor. This device automatically detects the output from the DVI source. I then set the device to convert the computer graphics signal to a video signal and I have chosen 720p although 1080i and other formats are also available. Video from the Pentax EPKi via the Gefen Scaler is routed into an HD-SDI cable. in the photo below, in the lower left corner is the auto detected signal. In the lower right corner is my chosen output.
I then capture the HD SDI signal with an AJA Io HD ($3495 in 2011 at bhphotovideo.com) which integrates reasonably well with Final Cut Pro. This device auto detects the type of incoming video signal. The software with the AJA Io HD device is highly flexible with many (almost bewildering) choices for compression before output. I have settled on using the full resolution Apple ProRes 422 10 bit for 1080i capture, the Apple ProRes 422 for 720p and DV for SD video. Although all of the video could be captured at the highest resolution to avoid switching settings when changing endoscopes, file sizes might be unreasonably large for the lower resolutions. Consequently when I change in the scope, I change the video capture settings and Final Cut Pro.
The Olympus high definition endoscope ENF-VH ($26,700 in 2012) is coupled to an Olympus OTV-S190 Visera Elite processor ($22,500 in 2012) which has a DVI output as well as a HD SDI (High-definition serial digital interface) output. Since the light is not integrated into the video processor as it is in Pentax, a separate light source is necessary. A Visera Elite Xenon light CLV-S190 was utilized ($12,500 in 2012). (Total retail cost: $61,700) There are also standard definition video outputs. For my use, the HD SDI output is more convenient for video capture saving me the need to send a signal through a scaler and I routed the Olympus video into the second HD SDI input on the AJA Io HD device. I then use the AJA software to switch between the two video processors or between the various resolutions that different endoscopes offer.
Video processor added features: I do not use any of the patient data features which allow you to type patient information into the video processor and have it displayed overlying the image. Since I show video images and print still photos from them, I prefer to keep all my video images anonymous and have the data stored as metadata. Then, should a video or photo presentation require patient privacy, the images of the larynx have no visual data present. I can use the Final Cut Pro program to overlay text later if desired.
