spot of bother with the PVR, running the PVR (with capture board) in a dual Pentium 100 ASUS m/board (1 cpu installed) EISA/PCI, Seagate 4gb HD for PVR use, 128Mb ram, Seagate 2.1gb HD for DOS, WFW 3.11. When bringing sequences of .tga files in the process just stops after about 150. No error message or anything. Won't go beyond that. Also, backgrounds seem to be skewed and distorted sometimes. Sometimes frames that were frame rendered look like they have fields – almost as if the fields were offset horizontally. Image looks fine in other graphics packages. Quite a few problems with the hardware, so far. DPS has suggested we may need to make the CPU run at 90 instead of 100Mhz. Any ideas? Anybody else having any bother? Martin

Martin, I had some setup problems with the PVR but nothing major, just some file tweaking and a bad cable on my side. I have been able to load a sequence of Targa file (760 frames) with no problem. Here is what I did notice: If you load images that were done at the standard 512×486 size and elect to resize the images, you get a playback that is junk, but it does play back. If I load the files without frame resize they play fine and look OK except for the frame size. I have also noticed that there seems to be some major differences for the gamma setting for the PVR as well. Files that are rendered to 1.8 gamma as significantly brighter on the PVR. I posted a question on this but got no replys. Single frame images load fine, no field effects as you described. Premiere is working OK with the PVR, and I can cpature video with no problems. I will say the output of captured video is spectacular, no artifacts at all at the 4mb setting. Hope this all gets fixed with the NT version, Tom

Tom, what kind of machine are you running your PVR on?
#183503From: Thomas FlanneryAug 3, 1995 10:43 PM
I have it in a dell XPS P90 with 64 meg memory and a 1 gig and a 1.6 gig disk. I have the Microp 9 gig drive for the PVR. The board fits nice in the bottom slot of the Dell and leaves the other two PCI slots open. Cheers, Tom

Tom, >> I have it in a dell XPS P90 with 64 meg memory << ah hah! you have a 90 too. I might get a 90 m/board just to see if the timing has anything to do with it. Martin

>>> I have it in a dell XPS P90 with 64 meg memory << >ah hah! you have a 90 too. I might get a 90 m/board just to see if the timing has anything to do with it.< Most of the newer mobo have jumpers to select 75/90/100 speed. I have a Dell XPS 90 that I clocked to 100MHz by moving a jumper. Hopefully when I get my PVR I can still run at 100MHz.

Tim, I'm going to try to clock the m/board down to 90, but I need to call ASUS to get the info on the method – the jumpers in the manual don't match the m/board's – ack! Martin

The board fits nice in the bottom slot of the Dell and leaves the other two PCI slots open.< Is that a Dell Mini Tower? I have the same system, but I don't have my PVR yet. Do you have the capture card? My understanding is that you couldn't use that PCI slot with the capture card installed. I'm looking to get a 4 PCI slot mobo. The Triton boards usually have the PCI slots to the right of the ISA slots, where the Neptune mobos have the PCI slots to the right of the ISA. That would allow you to use all 4 PCI slots on a Triton, the PVR/capture card combo would overlap a ISA slot. On a Neptune mobo you could only use 2 of the 3 PCI slots. With the PCI 8 channel 16 bit audio card coming from DPS I need all 4 PCI slots. I want to use video, SCSI, PVR, Audio cards that are all PCI. If I had another PCI slot I would through on a 100Mb/s PCI ethernet card. Oh well, I'll wait for the dual PCI bus P6 machines.

Tim, Yes, that is the mini tower. The PVR fits in the bottom slot with the capture card at the bottom of the case. This lets me use the last slot and still have the other two PCI slots open. I have one used for my video card so I still ahve a PCI slot free. There is enough room in the bottom of the Dell mini to allow for the capture card to fit with no problem. Sorry I took so long to get back, I've been in Hawaii… Tom

Or do all the cables plug into the PVR? I was going to get another mobo because I heard the PVR wouldn't work in my machine. I think I may still swap the mobo now that I heard about 3DS MAX. I want to get a dual smp mobo for NT. Plus the DPS PCI audio card is coming and I will need four slots because I also have a PCI SCSI card. Thanks for the info.

Tim, Glad to be of service. The PVR only has connections to the main board. Tom

Just wanted you to know that I recently set up a PVR on a P-90/32Meg Ram with a Microp 9.1 Gig and had what appears to be the same problem. When importing targa files from the local hard drive had a 157 frame limit. When importing over our network we did not have the limit. After several days of head banging, which all too often translates to computer bashing, we attempted an import again and the problem no longer exists. The problem here is that I cannot tell you exactly what we did to correct the problem. We changed graphics cards from ATI Mach 64 to Imagine 128, changed Simms, and worked with autoexec.bat and config.sys settings. There are also some codec settings and import settings in the DPS software we changed. Now everything works, including all device drivers in memory. We were working on a different problem at the time and sort of stumbled across the fix. Over the weekend I will try to backtrack and see if I can narrow it down. I was told DPS was not aware of the problem as of about 5 days ago. Hopefully we can come up with a solution for you! Eric Roberts Avogadro's Memory

Eric, >> When importing targa files from the local hard drive had a 157 frame limit. << that seems to be the limit we are hitting, but it is over the network, not locally. If you could figure out what you did, I'd appreciate it. Martin

Hi Martin, I can vouch for the 100 mhz vs 90 mhz setting…..sort of. I was originally installing my PVR in a P66, which runs at the same speed as the 100mhz (Assus as well). It would seem to initialize and operate, but some frames had a "glitch"….horizontally displaced bands in the image. I installed the PVR into a P90 and voila….perfection! Regarding your import limit of 157 files: you are probably highlighting the names of the files that you want to import. Instead, just highlight the first file in the sequence you want to import. The PVR "automatically" looks for the sequence and will continue importing until there is a break in the numeric sequence. For example, if you have a sequence of TGAs with numbers 0000 thru 0372, but file number 0245 is missing, highlight file number 0000 only and the PVR will import up to frame number 0244 and will stop because the sequence is broken. You can restart the import sequence by highlighting frame number 0246 and the PVR will import through to frame number 0372. Unfortunately, the PVR will not join these sequences…..you end up with 2 seperate .ani files. I miss this feature from the PAR because we frequently "bleed" TGAs from our server, appending them to the proper .ani file. With the PVR, you must have the entire sequence of TGAs online to be able to create a single .ani file of the animation. A bit of a pain in the A…!! Hope this helps! Later, -Jeff

Jeff, I am (as I write this) trying a jumper setting on the Asus m/board which may slow down the PCI bus to 30Mhz. Fingers crossed it will work. If not I need to get a new m/board for it anyway and I'll get a 90Mhz one with enough slots for the PVR and a sound card. Right now I don't have the room for a sound card – bummer. Right symptoms sound like mine, WRT the horizontal shift. I do highlight the entire sequence. I thought that was the way to do it. Hmm. I'll try that again with your method. It seems like you need Premiere 4.0a at a minimum to make good use of the PRV, although I've had good luck with the playlist feature. Thanks for your suggestions. I'll let you know if they work. Martin
#183808From: Jeff RichardsonAug 6, 1995 8:22 PM
Martin, I too have had excellent success with the playlists. We primarily do raw graphics…..black header and footer, bars, copyright, etc. along with the animation. Instead of doing the ever painful "JOINS" on the PAR, the playlist is much simpler. Nonetheless, it would be useful to do an occasional join on the PVR. I likely will end up with Premier or Razor to work the larger mechanical and mining simulations that we do, but I'm waiting until after Siggraph to see which one (or both) I choose. Gone to Siggraph, -Jeff

Jeff, >> I too have had excellent success with the playlists. << playlists are an excellent feature. We used to manually click on a black image, then bars, then slate, then logo, then animation #1, etc. What a PITA <g>. >> I likely will end up with Premier or Razor ….. but I'm waiting until after Siggraph to see which one (or both) I choose. << me, too. I'm going to evaluate the 2 at Siggraph. I'm leaning towards Adobe right now, since we don't do heavy duty editing – that's done with much better equipment generally (Flame, Harry etc). see you at Siggraph! Martin

Hi Martin, It was nice to meet you at Siggraph. Congrats on your special showing at the 3DS party! Later, -Jeff

Jeff, >> It was nice to meet you at Siggraph. Congrats on your special showing at the 3DS party! << good to meet you too 🙂 The Herbie video has got us a lot of attention and even won some award from Alias/Wavefront (best of show or something). Should lead to some more work with the ILM dudes. Martin
