I have a Performa 638CD with the video in/tv tuner. What is the best way to connect it to a powermac so i can edit and watch the video in a better resolution, will a serial cable with appletalk do ?Bert Total 68K Macs liberated 3 Quadra 610, HD 535MB, Mem. 32MB, OS 8.1

Can't be done, the VidCap and native display resolution on the 630 Video System cards is really only 320x240. This raw data feed is line doubled in hardware on the card to the specified 640x480 display resolution.The Mobo/OS never actually even sees the Video feed, do a screenshot on the mac and you'll notice that the OS is just throwing window consisting of a blank screen onto the desktop! (btw: THAT is the still unanswered solution to the "fib" quiz from waaaaay back in the early history of the MLA!  ) A network feed would be just as blank, AFAIK! It would be interesting to find out if the built in sound system on the Mac ever even sees the audio feed? Sound gets piped thru to the mac's speakers just like the pixels hit the phosphors on the CRT, but I'm not so sure you could grab the input with software! jt  ™.

Well you could at least edit them on the powermac. Just capture all the footage on the 630 and use ethernet (a serial cable would take ::forever::) to transfer them to the PM.--------

Here's a few articles that might help you:http://wuarchive.wustl.edu/systems/mac/info-mac/info/_Hardware/quadra630-tv-video-review.txt http://www.ctcnet.org/r981shap.htm http://www.byte.com/art/9410/sec4/art4.htm Looks like Apple Video Player should do the trick. The challenge is in getting the data from the Performa to the Powermac. The serial port is too slow, although I seem to remember hearing of some tricks for boosting bandwidth (some sort of sychronous, clocked cross-over cable magic or something). If you are looking to make low-res, low frame-rate movies for the web, then an Appletalk connection through the serial port might be OK. But is you want to capture decent video, you will discover that a minute of video takes several minutes to transfer over a serial port-based network (and since the TV tuner is in the PDS slot, you can't get ethernet). One solution for faster transfers is an external SCSI drive that is first plugged into the Performa for capture and them moved to the PowerMac for editing.

It'd be MUCH better to just get a NuBus or PCI card and capture the Video on the PowerMac or a NuBus 68k box. I don't think even an 840AV can keep up with VidCap on a good card and it is supposedly better than the NuBus PowerMacAVs.The 630 series is an awesome media display/playthru system! I LOVE them and it's fun to play with the capture features, but it is a HORRIBLE excuse for a VidCap platform! jt ™.

I'll need to check these out, thx!quote:

True about filesizes, but the Tuner is slotless and the dedicated Video Slot/Card I/O subsystem is the heart of the 630 series' awesome AV capabilities, The MPEG card would fill the PDS, but then you STILL have the Com Slot free for Networking! I LOVE these boxes! jt ™.

When I use Premiere 4.0 to capture video, I set the image size to
320x240 and the capture frame rate to 5fps with no sound. My VCR (JVC
HR-D820U) can play back video in slow motion at 5 frames per second
and this is what I capture. I then set the playback rate to 600% and
make the movie and it comes out to 30fps. Then I go back and record
the sound and insert it and re-record the movie. This is the only way
I know of to capture 30fps quicktime in a decient size window without
investing an arm and leg in additional hardware.
I still don't theink there is any way to get it to display/capture/whatever on a network, they're just talking about file transfers. Edited by - Trash80toG-4 on 02 Feb 2003 15:31:22 |

I have a external SCSI cd rom drive, if i just put a harddrive in that case i can use that to transfer the video files to the powermac. But will i get a better resolution and a bigger picture on there ?Total 68K Macs liberated 3 Quadra 610, HD 535MB, Mem. 32MB, OS 8.1

no . . . Unless you have a larger screen on the PM, but it'll still be the same 320x240 pixel sampe line doubled to a full screen 640x480 wherever you play it! Looks GREAT on the Intellicolor 20 on my Video Rack tho! The point is that you can display it at its best possible quality right from your 63x, but EDITING video on anything better would be a different story and well worth transferring the files if the PM is significantly faster. jt ™.

Actually, you'll be going to a tiny 640x480 window on that larger desktop (1024x768?) if you can get it to display at all without changing the overall resolution to 640x480. You'll need to go 640x480 to do full screen, that's a hard limit.I've had luck with a 640x480 window at 16" resolution on the 630 and in 1024x768 on the 6360, IIRC, but the raw data and the color depth in the video window will still be thousands, not millions! jt ™.

is this true with the 840av also? that whatever is captured will be displayed in the number of colors which it is captured in? (this is why when I would get a still from the AV in, I'd press freeze, and switch into higher colors... it works like a charm...if you want to have a really good video system, you may look into a PCI power mac, like a beige g3 with a wings (full AV) personality card or an 85/8600 Official 68k videographer |

I don't know about that . . . let's see . . . 
I just checked . . . if you wanna see the strangest thing, switch the 630 to grayscale and play a video feed in a standard sized window!     jt ™.
