Getting ready to shoot a short film basically in one day. Just now started wondering about some shots that might be good in slow motion. I have the T3i which shoots 60fps at 720p which I would use for the slo-mo shots, but I was planning on doing the whole film in 1080-24p. Would you see a big difference in these shots? Could I use 720p only for slo-mo shots and 1080p for the rest?

Using 1080p and 720p in one film?

im also planning on using 720p-slowmo with the t3i in a 1080p timeline.
for me im guessing im going to convert to prores 422, then take 720p to AE, slowmo that mofo, export as 422 again, bring into fcpx slot into the 1080p timeline, which would mean upscaling, but i doubt there would be an problems, unless of course i just fit it into the middle then add some background with vignette to try to hide it...
not too sure to be honest, i think input from others would really help.
or we could just test it more ourselves, which in theory we should do..

I guess there's the possibility of downscaling all the 1080p footage to 720p, but I guess my only concern is that 720p is too low quality? But I've seen 720p stuff that looks really good, and a lot of people say it gets a bad rap......I don't know...all I know is I don't have much time to figure it out, haha. Probably should have thought about this before.
oh i thought about 1080 to 720 but for me i just dont think anyone would take it as a serious short film then just some muck around.
so im going to upscale, il do some comparisons later and post them up if i have time

My thoughts exactly. But yeah, I guess it's just testing time.
Outputting terms of frame rate? Or like, to youtube, dvd, etc?
If all goes well I'd like to submit this to festivals, which will probably require putting it on a dvd.
Like I said before the final product will be 24fps.
Maybe I don't know what you're asking, haha. I'm still kind of a noob when it comes to rendering and formats and stuff....I've always just rendered my videos out in wmvs with no thought of the other options, but now I've started to realize that there are better configurations depending on the source footage.

Thanks for the replies guys! Looks like I'll be fine then, while I'm here...anyone know about shutter speed for 60fps? I hear it should be 1/125 but others say to put it as high as possible depending on light.
My DVD authoring software handles both, but asks to choose one or the other for the DVD. The reason, 1080p is NTSC and 720p is PAL.
That's not even remotely true.
As far as shutter speed goes, 1/120 is pretty close to a standard 180 degree shutter.
That is not the difference between them. The difference is NTSC is 30fps and PAL is 25fps...
I can select 25fps or 30fps for either 1080p or 720p.
But, the DVD authoring software specifies 720p is PAL and 1080p is NTSC.

I'm not sure what DVD authoring software you're using, but that's not what the difference is.
720 tends to be used in broadcast, often because of bandwidth limitations.
The difference between NTSC and PAL had to do with the power supply, the standard definition broadcast standard, and the frame-rate (which is linked to the power supply of the countries they take place in). PAL is used in 50Hz countries, and so shoots at 25fps (or 50 interlaced frames, say for SD broadcast), NTSC or 60Hz countries, compatible with 30fps(29.97) (or 60/59.94 interlaced frames), as well as 24fps(23.97).
This all relates to SD, more specifically SD broadcasting. It's not such an issue with HD, and you can quite easily shoot 24fps in a 50Hz country, just that you'd need a 172 degree shutter to reduce flicker, as opposed to 180 degree. You'd only really shoot 24fps in a 50hz country if you were planning on initially releasing into a 60Hz country, such as the US. Otherwise, if you were only planning to release in your own country, there'd be no point shooting 24fps in a 50Hz country, as you'd just be creating issues for yourself, especially with audio for absolutely no gain.
