getting super good super slow motion

Well correct me if I am wrong whoever is next in posting, but the Canon XH-A1 is capable of getting good slow motion, if you are shooting in 60i, that is because it is shooting 60 frames per second. Not bad but not the best if you are looking for the "Tiger Wood Slow Motion" or bullets exploding things. The people capturing that slow motion is by using a camera that has 100 to 200 and beyond frames per second.
Canon limit is at 60. At least to my knowledge it is. If there other way then I am asking the same question as you! HOW!

You can acheive nice slow-mo (50%) buy shooting interlaced and importing to a progressive timeline.
Anything beyong that in my opinion requires a camera capable of higher framerates.

I use Twixtor 4.5 to do frame interpolation in After effects till 100fps speeds without significant artefacts. Easy to do if you use 50i as a shooting mode.

If you watch my reel, around half way through, there are a couple shots of my actress on the beach that's XHA1 slowmo at its best. Click the link below.

There's two ways to get quick, easy slow motion with the A1 (and other cameras that can shoot in 60i for that matter).
The first way can be done with either FCP, or Adobe After Effects, but the second way is done only in after effects. Now of course there's other ways and other programs to do essentially the same thing, but these are the programs and methods I use.
The first way is if you're only looking to go about 50% of the normal speed. Just shoot in 60i (make sure your shutter is fast enough to capture quick moving objects), drop it into a normal 29.97fps sequence, slow down to 50%, make sure frame blending is on, and render. It's important to render afterwards because if you try to preview without rendering you won't see the desired effect.
Here is a video I did using this method:

The second way is with after effects. Now after effects could easily perform the same technique as mentioned above, I just find it easier to do in FCP.
First, create a new composition the same format as your footage (60i). Right click your footage in the timeline, choose time, then time stretch. Here is where you have more flexibility with how slow you want to go. Remember that with slo-mo in after effects it's different than FCP in that you're "Stretching" time, so enter a value higher than 100% to get slow motion rather than a lower percentile. This is where you just have to play around, but I've set it to 400% before with acceptable results. Once you've set your time stretch, go to your frame blending options and click the box until you see a solid / and then apply it to the composition. This turns on pixel motion where it will use two frames and a bunch of crazy math formulas to create unique frames within your footage. Sometimes you might get some weird things going on in your video, but for the most part it does a really good job. After that you can preview your video and you're done. I use this method only when I need to get my footage slower than 50%, but remember you can only go so slow when working with 60i fps. You can also change the fps to 24 if you need it to match 24 fps.
I hope that helps.

Yeah ecking, I'm aware of that procedure as well and it does produce the best results. The only reason I don't do it that way anymore is because I've been having problems with opening files in compressor and am in need of reinstalling it which I'll get around to someday. I don't like messing with my software while in the middle of a project in case something goes wrong.
