If i recall correctly, one of the problems with external plugins is that they are fed an image at the project's frame size and have to deal with that resolution. If you're working with straight video sources then this isn't really an issue because that's all there is to work with anyway. However, if you are using larger resolution stills, text, etc. then the plugin gets an already-rendered version and has to work from that. This means that anywhere the plugin ends up magnifying the image it has to expand pixels. Anywhere that it reduces the image it has to make some sort of compromise between resampling and throwing pixels out. So, in the long run, there isn't much that the plugin can do but work with the material it's been given.

Satish's Wax 2.0 should be out any day now. From what I hear, it should do everything 3DLE does and more. Maybe there's some resolution improvements, too.

Thanks for the description Kelly Would that mean then that if you work in full resolution in the preview Window The same way when you take a picture. You would get better quality. OUTSTANDING If it works Thanks also BStanding I was not even aware of Satishs Latest EXCELLENT !!

Mark, i don't believe it would be dependant on the preview screen at all. Vegas renders the current frame prior to any plugin effects, then hands this frame to the plugin for further processing. At this stage the frame would match the project or rendering settings, not the preview window size.

So maybe this means you could temporarily set you project to, 1440x960, render to AVI with the plugin working with higer res images (assuming stills being used here) and then reimport that section into a 720x408 project.

I'm gonna give it a go.

Oh Well I Started wiv nothing I finished with nothing. I spose I will have to get by keyframing in commotion for best results not the ideal solution !

Great thinking iblis summit good came outa it anyways.

Well it certainly works - I loaded a picture from a 3megapixel canon S30 stills camera and copied the event onto a second video track. On the top track I zoomed in using the event pan/crop, and on the second track I use the 3DLE plugin to zoom in to the same degree.

Next I opened up the preview window to a larger size. Going between project settings of 720x480 and 1440x960 the top track (Vegas pan&crop zoom) looked good in either res, while the second track (3dLE zoom) looked so much better in the higher resolution.

The down side is the render time - I'm rendering the 22 second still clip to uncompressed AVI at 1440x960 and it's taken about 11minutes (I should add that the track has a key frame set to default at 0 seconds and full zoom at 22 seconds, so this has increased the time.)

Other observations: Using the built in zoom is far more CPU friendly, the 3DLE really ate into the preview frame rate. This isn't a critisism, and obviously you can do more with the 3DLE, but if you're sticking to zooms and pan/crop, you're better off using the built-in track motion and pan/crop CPU wise.

For the few times I may have a need to Pan and crop a piccy then this will be very usefull ! I thought that imaginate was the only way and perhaps not as many functions but I started wiv nothin and now I/we got a new tool thanks Iblis !

Exactly.

I'm often seeing folks in here recommending 3DLE for simple pan/crop uses. True, it can handle these fine, but it's way overkill for this purpose and slows down the process significantly. If you want to do 3D rotations then by all means use Satish's wonderful plugin. But why people use it for pan/crop when a much more efficient pan/crop function is already built in leaves me scratching my head a lot.

Kellsie, interesting thread this .. Can you tell me something. I've recently done some, a lot actually, 3D stuff. Which, would you guess, is the quickest to render:

i) Pan/Crop in VEgas Pan/Crop

OR

ii) Pan/Crop in Satish's 3D

. . just an obseravtion . . I did a 5 minute thingy for a client over the last 24 hours, and it took nearly 3 hours to render .. just wondering if one way is faster than the other - yeah?

Regards,

Garzie

to conclude:

- I rendered at 1440x960 using MPEG2 at a constant bitrate of 15,000,000 (from the custom options) and the file only took about 20 seconds longer to render than the uncompressed AVI, but was 43megs instead of 2.6 gigs looked just as good, and also played back at a slightly higher frame rate due to lower disc overheads.

- You can't have a project at 1440x960 and render to 720x480 (therefore bypassing a step), as the result is the same as having the project at 720x480 and rendering to 720x480. You MUST render to 1440x960 then import the hi-res render.

- Rendering the 1440x960 file to 720x480 looks great - it's worth doing the whole 'render hi-res>render back for the quality of the results obtained.

-time to render the 22 second 3DLE clip to 1440x960 MPEG2: ~11 minute
-time to render 22 second 1440x960 MPEG2 to 720x480 DV: ~1 minute

- playback frame rates with preview at 360x240:
original clip with 3dle - 29 fps
rendered 1440x960 mpeg2 clip 20 fps
1440x960 rendered to back to DV (720x480) 29 fps

-playback frame rates with preview at 720x480:
original clip with 3dle - 7.5 fps
rendered 1440x960 mpeg2 clip 11 fps
1440x960 rendered to back to DV (720x480) 29 fps

Grazie, i'll have to try some tests, but i would imagine that choice i would be substantially faster. Internal processing is almost always faster than an external plugin, unless of course the original software authors just wrote a very very lousy subroutine for that particular function.

. . hmmm .. yeah you are proably correct . . I did have fun with the Satish 3d . . I've got stuff flying all over theplace .. but it really does take some rendering . . phewwww....

Grazie

Grazie - To go some way to anwsering your question, the same zooming in effect that took ~11 mins to render to 1440x960 MPEG2 took ~2minutes to render using the built in pan/crop. Plus the final results looked better.

So if you don't need the extras that 3DLE offers then performance with the built in pan/crop is so much better.
Grazie wrote on 2/27/2004, 10:44 AM
Thanks for that Ibliss .. . yeah, I just need to "juggle" the effort going back and fort between Satish and Vegas . . may just right-off the render speed for just the ease of use staying in one module . . Satish is great for zooming stuff around the screen . .

Thanks again,

Grazie

I dident even consider the render side of things but that can only be a bonus. I think using The plugin is / was just convienience. For me NOW anyway its a quality Issue I may never take a Film further than the computer but its important to know that if you finally make a DVD ect then there wont be any nasty surprises like image quality is so badly compromised your footage ?@;WL ..

Thanks iblis some very good testing data !!
