Digital/analog converter recommendations?

I own a DataVideo digital converter that I have had for a couple years but recently it has been giving me problems. It tends to go in and out giving me the video then a pink screen. And when it starts "flashing" like that my FCP will start stoping and starting during playback. And three times in the past week it seems to be the cause of my "ejected" Seagate drive that holds my media files. I will suddenly get the "premature ejection" sign.
So, my guess is it is going out on me and before it causes something horrendous, I want to get a new/better one. Any reccomendations?

If you ever do VHS, Hi8 or other SD to DV conversions, the Canopus ADVC300 does a very good job of cleaning up the image.
Cheers,

Audio Digital Analog Converter bit resolution

Hello ! i´m looking if I can use IPHONE to make my investigation project. Someone of you know which is the audio Digital Analog Converter bit resolution for a normal audio conversation? 13bits? thank you very much

MonoPrice.com has a digital to analog converter for around $25 although it looks like it is on back order. I would give them a call anyways. Don't get fooled by their prices, they are fast and cheap but good and the place to buy all your audio and video cables. I wired up my sisters entire home theater for less than a quarter of what I payed for my first HDMI cable which I didn't pay much for either.

Set values for the Lock-In Amplifier's Digital Analog Converter Channel?

If I let my user have the freedom to select whatever values they want to select in order for it to show up as the output value for the Digital Analog Channel then I cannot understand why use ibwrt(...) and ibrd(...). Because ibwrt is going to write a specific voltage at the specified channel since the manual for the Amplifier states you must input the string for writing output voltage as DAC2 3000 (the 2 signifying the channel and 3000 - the millivolts). If this hard coding occurs by using ibwrt then how can I write my code so that the user has the capability to change the voltage value and the channel to the one they want? Thanks in advance.

Do I need a Fmt and ibwrt for both DOutput and VOutput? Because DOutput is indicative of the channels 1, 2, 3, 4 in the Lock in Amplifier and the VOutput is for the amount of volts the user can set (i.e. write to the instrument). Also I found this on the following NI website regarding filling in the value of the write buffer: Write Buffer Value. This website signifies that one must use \002 and end with 003\ which I am not sure I even need for this instance of initializing the writeBuffer[8]. Also I used [7] for the writeBuffer because I thought arrays went 0, 1, 2, 3...so on therefore writeBuffer[7] will give me space for 8 bytes? Is that an incorrect assumption? Lastly, here is my modified code according to the changes you mentioned and it still is giving me Non-Fatal Run Time Errors and not communicating. Is there anything else I am missing out on which I can't find. Seemed like I may be making this code much harder than it needs to be. Thank you for your time.
Sincerly,

No Bluray Audio ....BluRay HDMI'd to TV, TV audio to Digital/Analog converter: No audio to receiver

I have a new Sony BluRay connected to a Toshiba 32C11OU TV via HDMI.
Have TV audio going out through digital audio out (optical) > digital/audio converter (RCA) > to stereo receiver to play on sound system.
I am getting no audio through stereo receiver from BluRay or Netflix, only a loud fluttering sound. Funny thing is I can hear YouTube through this setup only.
All other audio (cable, Xbox) works fine with TV audio going out through converter to receiver.
Also, I can hear audio(DVD, Netflix, etc) fine through just the TV speakers without using audio converter
Help Santa,
thanks,
Steve
Solved!
Go to Solution.

Thanks for your reply. Finally got a solution through Sony (BluRay brand) forum. My Toshiba TV working great!
For anyone else with same issue I'll post what worked below for my Sony player:
Try going into the Audio Settings of the Blu-ray player. Change the Digital Audio Output to PCM and BD Audio Mix Setting to Off.
1. Press HOME button on the supplied remote.
2. Go to Setup (ToolBox icon) by pressing the left arrow button.
3. Press the down arrow button and select Audio settings.
4. Select Digital Audio Output and set it to PCM.
5. Select BD Audio Mix Setting and set it to Off.

Using Canopus ADVC-100 Analog to Digital Video Converter

Does anyone know if the Canopus ADVC-100 Analog to Digital Video Converter will work with FMLE 3.1?
While FMLE recognize it as a video source?\

Do we have Digital to Analog converter with high current output?

Do we have Digital to Analog converter with high current output? I need 8 channels and each channel has at least 100mA current output.Thanks!

I have never heard of such a device. You will probably need to follow the D/A with an amplifer for each channel.
What is the voltage range and speed required? Any special protection requirements (such as current limiting)?

Convert a rpm waveform to digital/analog tach signal. Sound & Vibration

Hello,
my question is: How to convert a rpm waveform to
digital/analog tach signal for use with SV application?
Or is it possible to modify the SV - VIs for the use of
a rpm waveform or a speed signal?
Thanks a lot for coming answers.
Thomas Nuding

Typically an RPM waveform is the analog view of a tachometer, such as a proximity probe over a key or keyway, or an index pulse from an electric motor. In most rotor dynamics applications, the phase of the tachometer waveform is compared to the phase of other waveforms, such as vibration, to determine the angular position of the shaft when the other waveform occurs.
The sound and vibration tools have a function for calculating RPM from an analog tachometer waveform. The order analysis toolset go further to add a counter as an tachometer input. The OAT tools also allow for selection of rising edge or falling edge and voltage level for the "trigger". A time instance is recorded when the edge occurs. This time instance is used for phase measurements and for resampling the other waveforms into the angular domain, ie. 360 measurements per revolution.

Using Air Port for music...do I need a digital to analog converter

I want to play my iTunes library on my old stereo using my iPod Touch as a remote control (that works well with my Bose Wave Radio). My old stereo is an analog system. When I plug the output of my Air Port Express into my stereo though RCA cable, do I need to use a Digital to Analog Converter (DAC) or is there a DAC as part of the Air Port Express???
Many thanks,
Twinz

After doing a little more digging, I find that using a Toslink cable out of the AirPort Express and into a quality external DAC, and then using RCAs to connect to my pre-amp will get much better results out of my stereo. Evidently the DAC in the AirtPort is not great quality. So, what I'm going to do is hook up the stereo through the AirPort and listen. If it sounds bad, I'll spring for a decent external DAC. Many thanks!

Recommendations for purchasing an analog converter?

Looking for recommendations for purchasing an analog converter to transport Hi8 movies to IMovieHD 5.0.02. I have found Datavideo DAC-100 and Pinnacle Studio MovieBox DV version 9...which purport to work. Suggestions much appreciated.
Power PC G5 Mac OS X (10.4)

Hi WWG3
Just bought and used a Canopus ADVC-300. Fills my need though it seems
to have an internal timecode that fills gaps from dorp-outs. MY GUESSING.
Anyhow the result was to my satisfaction. The box also had many video and
audio enhansing (destroying) functions which in my case gave a very plesant
result.
There are more versions to consider:
Canopus ADVC-55
Canopus ADVC-110
Pyro AV link
DAC-100
Director's Cut Take 2
ForeMac Studio
(Hollywood bridge - if it still is manufactured) - Had one and accidentally
killed it by turning the FW-connector 180 deg wrong. (I think it was rather
unreliably)

Quality capturing with FCP & an analog converter?

i am making VHS(PAL) -> DVD transfers using a Canopus ADVC110 analog converter with iBook G4 with Tiger. previously i was using iMovie HD in capturing which worked fine and gave me good quality DV files, but since i needed more editing possibilities i turned to FCP. i was surprised to find out that it looks like i cannot maintain the quality nowhere near where i've used to since FCP (i have FCP 4 only unfortuntely) only produces me small-sized Quicktime Movie files with mediocre quality compared to the huge but good-looking DV files i got with iMovie. the quality of these is simply way too low for me. and i cannot use iMovie HD for capturing and then import the files to FCP because FCP 4 doesn't understand iMovie HD projects. now am i just being stupid and missing something with the FCP settings here? or is updating my FCP a solution?
i don't need to work with DV cameras, just with VHS->converter->iBook combination.
i'd be very grateful for quick tips/solutions.

A few points: [cliff notes version: get a monitor]
1. Without a TV (aka NTSC/PAL Video Monitor) to see your footage sent out via Firewire, you have no way of know what your footage looks like. QT may do a better job of representing DV stream files, but it in no way means they are of higher quality.
2. Capturing in Final Cut Pro IS computationally intensive. Here's why. DV stream, (the stuff iMovie uses) is a direct write out of the muxed (mixed audio & video) as it is written on the tape by your camera. FCP (or more accurately Quicktime) takes that Muxed stream and separates the audio and video into individual streams IN REAL TIME. If the computer can not keep up, dropped frames or corrupted files are the result.
3. This demuxing does not change the QUALITY of the video. The file started as ones and zeros and remains as ones and zeros. There is nothing to convert at this point - it still is a direct digital transfer - just pulling apart the strings.
4. Playing these more complex Quicktime files places greater demands on your system than iMovie's DV stream.
5. The people who wrote FCP recognized that displaying a high data rate file on a limited computing platform may overwhelm that platform. So, in response, they designed FCP to create a low resolution proxy for the display.
6. Why do this? Now listen closely .... because FCP is designed as a Professional application and professionals (or serious dilettantes) will invest in the proper equipment to monitor the audio and video components of their work This is how a SOFTWARE based editing solution can compete with very, very expensive hardware based systems. FCP is quite scalable. It will run on the minimum configurations but really works much better with more horsepower.
Now, the limited ram, video speed, hard drive capacity and frontside bus speed of your computer is being tested by this process and is not holding up well. A second hard drive to be a dedicated media drive will help. More RAM will help. A faster CPU will help. A machine that is configured from the beginning to run these kind of applications will help.
I'm not trying to be mean here, just trying to explain the complexity of the situation. I really do hold the Apple marketing people responsible for over selling the program. It is NOT rocket science, but does demand a much greater understanding of technology than most people I know to able to actually grasp.
good luck,

Digital Video Converter

i'm a little confused about the difference between 'apple video adapter'
http://store.apple.com/Apple/WebObjects/ukstore.woa/6224040/wo/WB5d0bwOOsXt2cAsU qR1RKWHU7b/3.0.19.1.0.8.25.7.11.5.3
and a digital video converter -
http://www.canopus.com/products/ADVC110/index.php
i don’t want to mirror my ibooks monitor, but create an enlarged preview screen in fce
can my ibook do this?
i also have another problem. The Canopus converter uses firewire, and i only have one firewire port.
To add, i want to upgrade from a usb2 external hard drive to a firewire! just because i've recently read that it will work better as a scratch disk.
i seem to have too many devises and not enough ports.

About the first question:
- the Apple Video Adapter allows to use an external TV screen in place of your iBook screen. I have it but never use it since my video (iMac 20") is far better than a TV screen.
- a Digital Video Converter, instead, converts DV video into analog video and viceversa. In your case you could plug the DV end (firewire) to your iBook and the analog end to a TV set, and use it to "Print to Video" the Canvas of FCE during editing or previewing.
The main difference is that in the 1st case all you do on the iBook appears in the TV screen, in the 2nd case only the canvas output of FCE (or iMovie if needed).
To edit video use the 2nd solution only; this has the advantage to show in real time, during editing, exactly the final result of your movie (colors, interlacing problems, etc.).
You might have another option: most digital camcorders include a video converter and can be used in place of a stand alone Video Converter; if your digital camcorder allows it, use it in place of the Video Converter.
About your second question, if you switch to a firewire external drive you should be able to daisy chain your camcorder (or digital video converter) to the external drive, so the single firewire port on the iBook should be enough. Just be careful, I know some combinations of camcorders/hard drives don't work well together when daisy chained... Not my direct experience, but I read it in these discussions.

Black magic SDI to analog converter box code issue

Hello im using an SDI to analog converter box from black magic and since i was using it to test some other stuff I guess i got the code worng now but don remember what it was. As of right now its only displaying some lines although i can kinda see through and im seeing what the back ground is and it its what im trying to display.
This topic first appeared in the Spiceworks Community

I wanted to let you know that I made a practice dvd today, sampling edited clips from four different sources of imported vhs video--some of it 16mm dubbed to video around 20 years ago--into iMovie. I worked in the update of 6 to see if the application had stabilized at all. I've been working only in 5.0.2 recently.
I was pleasantly shocked at how much better the video quality was than on the computer--as you foretold. I really couldn't tell a visual difference from the source videos. What a relief! But do you work with that disparity, the difference between computer and TV, without a live TV monitor as you go? It's hard to make decisions on the basis of how it looks on the computer.
Other encouraging news: the garble around the edges didn't show at all on the TV screen. In the meantime, I'd been trying the plug-in you recommended. I'm glad I won't need to it for all this video after all, but I'm curious to experiment more with it. Any other plug-ins you'd recommend?
Thanks again for your generous response.
On a roll,

Macbook Pro as optical to analog converter

I've noticed that my Macbook Pro has an optical/analog audio in and an optical/analog audio out. My HDTV has only an optical out, and my home audio system has only an analog (stereo) input. Can I use my Macbook Pro as a digital to analog converter? That is, if I connect my TV to the Macbook Pro using an optical cable, and connect the computer to the home theater system via RCA cable, will I get sound? If so, will the Dolby output from the TV also be converted?
Thanks for your input.

I'm pretty sure that the only way to do this would be by hacking something together with VNC, which sends a desktop frame-by-frame across a network connection. Because it goes over the network, it's not even in the same league speed-wise as DVI. In fact, even when I connect my PowerBook to my MacBook Pro over gigabit ethernet, a VNC connection is too slow to play even a modest video.

Capturing Digitized Analog Video

When sending digitized analog video to iMovie or to another Video editing software, the very first image is clear and bright (for only a split second) then a shade of gray comes over the preview/import window and the rest of the imported movie is grayed over.
Workflow sequence is:
1. VCR Player
2. ADVC-110 DV Converter
3. Mac Pro
4. iMovie or other video editing software
My first try at converting a VHS tape to digital worked fine. This second tape . . . not so good.
Thanks in advance - bob

Paul, when I purchased the Plextor unit, VideoStudio did not come with the package. I notice on the Plextor web-site that the current product does have VideoStudio bundled with the converter. I also notice that both InterVideo WinDVD and VideoStudio are Corel products. Are you telling me that VideoStudio would not conflict with PE7 whereas WinDVD would?

What is best fiber optic to analog converter to use with RCA cables to receiver?

What is best fiber optic to analog converter to use with RCA cables to receiver?

OK, in that event I would get a Toslink to analog converter. There are many sources for these, such as Monoprice and Amazon. They are not expensive.
The fiber optic cable itself is incredibly cheap. Practically free. Don't spend a lot of money on one.
