Part II: You do not mention if you have benchmarked your drive subsystem at a specific data transfer rate. Try a package such as PCTools to determine your drive throughput in Windows. It is possible that if you are trying to capture uncompressed or RAW video, that your disk subsystem…
Thermal Recalabration is performed on all hard disks to insure correct drive operation due to expansion and contraction from heat buildup or cooldown. "AV" series drives perform this task in the background without interruption data flow during intensive read or write operations. You certainly can get an "AV" type drive…
Bill, part of your problem might stem from a Thermal Recalibration disruption on your hard disk. Digital video is very sensitive to hard drive TCAL's. I have had to replace several otherwise good hard disks with "AV" versions to rid myself of frame drop problems. Dean
#MPEG Encoding service
Message #3212
Patrick, I am sending you some literature and pricing info. I have not used too much M-JPEG as most of my jobs also include audio streams as well. And no, I am not familiar with Media 100, can you let me know what it is? Dean
Gerard, I am not a very big fan of the board, (I am sending mine back) but I will do my best to answer your questions. > Be aware that the sound capacity of the Marvel board for playback only. There is no recording ability at all. The sound output…
Hi David, OK first MPEG is not so much a specific standard but a set of guidelines regarding compressed video. Also, MPEG was originally designed to be a "hardware" codec, meaning that a chip is required to both encode and decode the video stream. However, there are some software MPEG…
Yes, I have it. It is ok, the image quality is great but they have not solved the frame rate problems yet. I suspect VidCap software. Also by the time you get the full package of add on's, it becomes expensive. Mine cost over $1600 and did not even come…

Capture board
Message #2859
Neal, if you are shooting on BetaSP and want to retain a majority of your quality, you must use MPEG encoding at a high rate of speed, (at least 400mb per second). AVI quality is poor and when you realize that even the most aggressive hardware platforms cannot capture 60…

#Where is PCI capture??
Message #2856
Robb, there is a PCI based video capture board. The Matrox Marvel II board. It comes in several different flavors such as with RGB, MPEG decoder, and other options. I got mine about a week ago and love the quality but am not seeing the increased frame rate capture advertised,…
Hi Jim, I saw your message about the vertical sync error. I got that one too, it turned out to be a interrupt conflict with my Turtle Beach audio board which I was using to capture the audio portion of the clips. When I set the TB interrupt to a…
Bohdan, I saw your post about MPEG I encoding services. Our firm also does encoding services and is based in the Chicago area. Turn around times depend on the amount of source material to be encoded. We can also accept VHS, SVHS, 3/4", 8mm, Hi8, Betacam, BetaSP, and D1 materials.…
