#PAR – SLOW MOTION TOO ?

#88023From: James LockMar 2, 1994 3:37 PM
Questions for everyone: I routinely do real time vehicle motion to show the trajectories of automobiles during collisions. I presently use a Sony 9650 Hi-8 to record (single frame) and I always do a couple of slow motion sequences. These sequences are usually done in six frame copies to tape. I have been following the PAR info but I am not sure if it has the ability to copy or duplicate tga images any set number of times through my sequence. Is anyone aware of that capability? Is PAR THE answer? James Lock College Station Texas

James, The Par would work very well for your slo-mo sequences. You mention, >> I am not sure if it has the ability to copy or duplicate tga images any set numboer of time through my sequence. << You have the ability to specify how many frames per second playback from 15 fps to .1 fps or about 1 frame every 8 seconds. -JE

JE Thanks for the reply. I guess I should go ahead and bite the bullet. I always hate to spend the money but I love the results. JL

James, Considering the cost of the alternatives, the level of quality possible and the ability to go out to Beta Sp, there's nothing in its class. Just make sure you get the Micropolis drive, which is all that's currently being recommended according to DPS. (Model # 2210A 1 gig and 2217A for 1.5 gig)

The PAR software has the capability to playback normal 30 frames per second to a recordable slomo selectable at set intervals starting at 15FPS down to, I recall, 0.2 FPS. I sold some slomo footage of models splashing in the surf last week. Very sensual stuff. Martin Foster would have drooled! <BG>

Don, >> Martin Foster would have drooled! <BG> << quite probably <g>

Don, >> I threw that in there just to see if your reading everything. <BG><< actually it's really hard to read _all_ the messages anymore with CIM's extreme slowness. I must've been lucky to catch your quip. Traffic is massive and I'm going to try OZCIS to better handle it.

Don, Now that you have been beating on the PAR for a bit, I've got 2 questions. #1) Can you tell the difference between the PAR output and single frame? #2) Do you think a customer .. not knowing the PARticulars of how you recorded the animation, would notice a reduction of image quality . if delivered on BetaCAM SP? >> Slow-Mo Now that's nice. For previews .. one could render 1 image every 15 frames lets say and use that for customer approval. Ang

Your 2 questions: 1.) No question. The output is just as smooth playing but the PAR has better, much better output picture quality than the single frame. Now for the qualifier: I did all my single frame with a targa+ at tmode 11 512x486x24 and comparing to the PAR at 752x480x24 bit is just not fair. I think this question should be addressed to J.K. Jordan who uses an ATVista at 756X486X24. 2.) Can't answer the question yet because I don't have the beta SP deck yet. I can tell you that my 3/4 SP customers are very happy for the improved quality. They know what is my FBF and what is PAR on the 3/4 because the PAR quality is obviously sharper, and the color is tighter. I can tell you that one customer has switched to me for his slomo work. He was taking it to a local TV station to do it on their DT beta SP slomo deck. I feed his video in at QF 16 and output from the PAR at 15 and 10 FPS for his stuff in less than a half hour time. >>Now that's nice. For previews .. one could render 1 image every 15 frames lets say and use that for customer approval. Actually, I like what Greg does: Render your test animations at 376x240x0.851 for center screen window. It renders 3x faster and gives an exact miniature of the animation. Only problem with this is when using IXP's. they remain the same size, res independent and need manual adjustment. I wonder if Greg has a solution for this problem?
#88512From: Mar 4, 1994 12:55 AM
Depends on the IXP. All the ones we wrote factor in the resolution in their calculations, so the results are the same no matter what size you render at. This was always one of our priorities. Which IXPs are you having trouble with? By the way, great going with the slo-mo business! I love it!
#88564From: Don LandisMar 4, 1994 2:57 AM
I was refering to the IPAS disk #1 from YOST. These must all be adjusted when changing resolution such as the hilite. Have you rewritten these to overcome this limitation?
#88658From: Mar 4, 1994 9:56 AM
Don: >> I was refering to the IPAS disk #1 from YOST. Have you rewritten these to >> overcome this limitation? I can only write my own, Yost is responsible for theirs! <g> I know that theirs are done, we'll just have to see if they changed that aspect of them! Like I said, though, ours have always done re-scaling correctly to any resolution. Anything measured in pixels cannot. Greg Pyros
#88671From: Yost GroupMar 4, 1994 10:27 AM
Our IXP's on Disk#1 are written to work at fixed resolutions, with the exception of flare.ixp, which is proportional. That's just the way they work.
#88873From: Don LandisMar 4, 1994 8:52 PM
Considering that many will want to render at half resolution to do quicker tests wouldn't it be a good thing to make the future IXP's like hilite and glow resolution independent?
#88997From: Yost GroupMar 5, 1994 11:52 AM
I wish I had the time to go in and rewrite all of those IPAS routines, because I've got tons of ideas re how to make them better. Unfortunately, I'm resource-bound, and all development work is going into r4 and the new crop of IPAS3 routines.

>>With all the ambitious IPAS programmers here, maybe you can "allow" someone to rework them for you.<< Amazing, I was thinking the same thing when I read that message. I would just love to see those great .axps with some of those enhanced IPAS3 features that Gary talked about when he listed his upcoming offerings. John Tissavary (La Luna cie)
#89423From: Yost GroupMar 7, 1994 9:47 AM
When I see one of these ambitious IPAS programmers use the IPAS3 tools to the extent of our new standards, I'll be sure to contact them. Once you see what we've done with interactive real-time feedback in our new particle systems, you'll see what I mean. – G

Did you download the new PAR HEX file with the 5 second GPI trigger from the DPS BBS? Went up there today, I'm told…
#88565From: Don LandisMar 4, 1994 2:57 AM
Not yet. I'll go up there in a few minutes to check it out. I've been racing here this evening due to a JKJ PAR crash. Need to rebuild my demonstration for a meeting tomorrow at 10. It's almost 4 AM and I have 800 frames to rerender and compress. I should have known better than to use Join after the warning. Hope they get this bug fixed soon.
#88659From: Mar 4, 1994 9:56 AM
Don: >> due to a JKJ PAR crash… We'll have to add that definition to the dictionary. <g> That bug's been fixed Thursday, BTW. Download the newest set of programs. Greg Pyros

#88933From: Mar 5, 1994 2:13 AM
That's true, pass the message on to Don, he started it! (Coined the phrase, so to speak!)
#88925From: Don LandisMar 5, 1994 12:26 AM
>>We'll have to add that definition to the dictionary. I have two more for you: These are points in time like A.D and B.C. AP will from now on be used to denote " After Par" BP will from now on be used to denote " Before Par" Of course these terms will only be significant to upscale, cutting edge animators like us, right Greg? <BG> BTW I have only used my targa+ twice in two weeks AP <G> Are the days of my targa+ numbered too?
#88943From: Mar 5, 1994 2:43 AM
Don: Yes, my life changed AP, also. (Not including the fact that those are my mother's initials!) >> significant to upscale, cutting edge animators like us, right Greg? Right! Actually, it will also be significant to those who don't get one, because they'll start wondering why they started losing jobs to the CEA group who got the PARs! Greg Pyros PS: CEA = Cutting Edge Animators, another Don Landis-ism <g>
#89000From: James LockMar 5, 1994 12:00 PM
Don, well John Ellis also responded with the same information. We have a consensus <G>. Now I am wondering how I would sequence my frames, including the titles and fades. I am not too worried about that now as I just tell the sequence the in point and I can mix and match. I would like to get a user's manual for the PAR. I think I will check with Gary or someone on that. Thanks JL
