#3DSr3 Animations on Mac?

Can anyone offer insights into their success (or struggles) in playing back 3DSr3 (Targa) animations on an ImMix Video Cube post-production video workstation? I know that one definite option is to dub a frame-by-frame video tape to the ImMix just like any other video footage. But it would seem preferable to avoid the intermediate videotape step by transferring 3DSr3 targa files directly from the originating DOS PC to the Macintosh environment of the ImMix. A dealer told me that this can be done via a Mac-based graphics conversion program ("Babelizer" or something like that). Has anyone here tried this? Is rendering to Targa files the best way to do this, or would some other 3DSr3 rendering format be preferable? How good do conversions/transfers look by the time the animations are running on the Mac and ImMix? I'd appreciate any insights anyone could share. Thanks, Lee

We have done some non-linear editting at an ImMix facility. We recorded frame-by-frame to Hi-8 and then went to the Cube. Other than typical Hi-8 glitches, the system was a dream to work with. The Mac was a little slow with frame captures, and I don't know how well frame conversions go, so I couldn't say much about digital transfers of your animation. Let me know how you do.

David, Thanks for sharing your experiences with ImMix editing. We plan to order the cube next week, so I probably won't get around to actually editing with it until sometime in March. I'm looking forward to it. Thanks again, Lee

Keep me posted on your results. The post facility we deal with doesn't have a terribly convenient way for us to get single frames to their ImMix, so I'd like to hear your approach.

I called up Debabelizer on my MAC, but I didn't know what file format to look for. It will import the TGA files, and convert them to about 30 or so different formats on the Mac, but what was the file format you need? If you want to give Debebelizer people a call, they are Equilibrium Technologies at 415-332-4343.

Thanks for your helpful reply. Since our ImMix probably won't be delivered for a few weeks yet, I don't know all the answers to the good questions you've raised. I've heard that the Mac front end to the ImMix could handle either Pict or Quicktime files. In the end, though, the animations need to be transformed by the ImMix's custom processors to its proprietary Wavelet (compressed) format. Ideally, I'm hoping to find a reasonably animated way to do a frame by frame digital transfer directly from the Targa+ board (or files) to the ImMix's direct input. I don't know how feasible that is yet. If anyone else around here knows, please jump in with that info. Thanks for the contact info for the Debabelizer. Gratefully, Lee

I don't know any specifics on the ImMix cube, but isn't it a JPEG device? You can render .jpg's from within 3D Studio, and they should be readable on a Mac using Dosmounter or Debabbelizer. These image file formats (.tga, .jpg, etc…) are not platform specific, just the medium you store them on is.

John, Thanks for your reply. The ImMix cube does not use JPEG compression but rather its own proprietary "Wavelet" compression scheme. That's one of the key quality enhancements of the ImMix system. Do you know if it's possible to DOS-mount an entire SCSI hard disk (from my 486) on the Mac? If it were, that could at least solve the physical file transfer problem of getting large Targa animations from my DOS computer over to the Mac-ImMix environment. Thanks again for your suggestions, Lee

Every experiment I've done trying to mount a DOS formatted drive on a MAC has ended in total disaster – usually reformatting the harddrive without a prompt or anything! I've successfully ethernetted a couple of gigs using ethernet and Farrallon's DOS-MAC network setup. Kind of slow, but definitely works. John Tissavary (La Luna cie)

Gee, I don't have a problem with that. I have a 150 MB SCSI bernouli that I swap not only the whole unit back and forth from my MAC to my PC, but I can read PC formatted Bernouli disks on the MAC as well. I can use it for transferring large FLIC files or series of TGA files onto the MAC. On the MAC I have something called PC Echange (I think) which automaticaly reads the disks I put into the MAC and tells me if they are formatted for PC. Then it will ask me whether I want to format for MAC or read the DOS files without re-formatting.

I wonder if Bernoulli's and Syquests (being removeable media) are somehow able to do this. I've had the nightmares when trying to mount a DOS hard drive on a mac. John Tissavary (La Luna cie)

I don't think it is the fact that it is removable. I was having the same problems and nightmares until I started leaving this "DOS identifier" (for lack of a better term) active in memory of the MAC. I was formatting bernouli disks by accident all the time. Now it always asks me politely whether it should destroy 3 to 4 years of my lifes work, rather than just doing it on its own. <g> -Brian P.S. I believe it is actually called DOS Mounter. But it somehow stays active.

>>until I started leaving this "DOS identifier" (for lack of a better term) active in memory of the MAC.<< I'll have to remember that one. Thanks. I try and stay away from Macs whenevery possible, but it's hard in the graphics biz. John Tissavary (La Luna cie)
