“Now set a keyframe for Radius of New Particles at 0 and another at :5 value 0. ?”
At 0, meaning 0 timecode. Aka, the beginning of your composition (0 seconds). :5 probably meaning 5 seconds or 5 frames into the composition. What is the timescale here? is the animation taking place over minutes or seconds?
Make the last keyframe a hold keyframe.”?
Look up ‘Hold Keyframe’ in After Effects help
TrkMat to Luma Inverted Matte “Text”. ?
On the layer section of the timeline window, you’ll see a column called Track Matte (TrkMat). Whichever layer he is talking about here, set the TrkMat dropdown box to ‘Luma Inverted Matte “Text”‘ This uses the luminance levels of the layer named “Text” as an inverted dynamic mask for whatever layer you apply the trkmat to.
Set this layer’s in point to -5. ?
-5 I assume meaning -5 seconds or -5 frames, so 5 seconds or frames before the beginning of the composition.
set the out point to 1:15. ?
1:15 meaning either 1 minute 15 seconds or 1 second 15 frames. It depends on the timescale of this project. Do whichever seems more natural.Sorry, I didn’t have time to go through the tutorial myself, but I hope that helped. I assumed you knew how keyframing worked, etc. etc. so forgive me if it seems a little abbreviated.

I heard that in camera everything is recorded at 59.94 fps, and that play back skips frames accordingly. The N in PN, meaning Native, is supposed to make the actual recording at that chosen framerate (ie 24p = 60fps recorded, 24 fps chosen during playback and 24pn = 24 fps recorded), so yes thats probably why I see the slow-mo in camera. I’ve never recorded tests out of Native mode, since that mode gives you about twice as much room to record on.
I don’t want to squabble or anything, so I won’t press further, haha. Regardless, the HVX really is a great tool, isn’t it? It was def worth stepping up to from my old Canon XL1s, haha!
Happy filming!

That reminds me… one little thing with the animation codec coming out of Avid: When you select animation in the format options, make sure to set that Frame Rate to ‘Current’. I had it set on 24, but my footage was 23.97, so my compositing in AE was off when I brought in the new footage for the first time. Setting the FR to ‘Current’ resolved that issue.

What are your settings in-camera?
I have an HVX200 as well, and in film-cam mode at 24PN, if I switch the framerate to 60, my playback is in slow motion, because the footage was recorded at 60 frames per seconds, but played back at 24. Can the HVX playback progressive footage interlaced? I don’t have much video experience with the HVX and interlaced footage, since I don’t use interlaced footage for any of my projects.
Sorry, I’m just curious as to what your setup was.

If you shot on the HVX at 60p and are playing back at half that, shouldn’t the footage look slower?
As for which workflow, I believe that After Effects has a more powerful time-manipulation system than Avid. In the newer version of AE you can actually use frame interpolation rather than flame blending when slowing footage down, which gives a much smoother appearance. AE also has several custom plugins for time manipulation, one of which I remember being called ‘Twixtor’.
If you’re looking to efficiently slow down footage and still be able to key, I would use AE for both steps. I’m not sure how Avid handles slow-mo in post, but I imagine you run the risk of getting blurred/blended edges between the green and your talent, which makes keying all that much more painful.

Just tried it out using the animation codec, and the white flashes are gone! Its not every day that a problem is solved that quickly…

you might want to ask this in the Adobe Encore forum 😉

it would be tedious, but a displacement map might help with the actual translation of pixels in the distortion… then you could just use a color correct adjustment layer and maybe a touch of blur using the displacement layer as a track matte. Keyframe it to last a frame or two, and you should come pretty close.

One problem may be that your computer doesn’t have enough RAM to process all of the frames. RAM stands for Random Access Memory, and its what your RAM previews are stored in by AE. How much RAM does you computer have? If you are in Windows you can find out by right clicking ‘My Computer’ and selecting Properties. In the general tab it should say how much RAM you have. AE uses a maximum of 2GB of RAM on Windows 32bit
I’m no expert on HD either, but that kind of sounds like the reason behind your problem – at least with the fractal noise.

I think in a recent 3D Worlds tutorial it was mentioned that the set pieces were made in photoshop at the rough size they would be seen in the video. So I guess that means you don’t need to bother making them much larger than they will appear in the actual composition.
Of course that means you would need to plan out all of your moves beforehand…
