1080i60 as slow mo into 1080p24
My second workflow question of the day, but totally unrelated to the first. I do love the Cow…and I did RTF, I just may not get workflow well yet.
I have a large (for me) project that I just shot and must now post. It’s a sports/instructional DVD but the goal was to get an NFL Films kind of look. I shot in HDV 24F, except for stuff I knew we’d want to slow mo which I shot 1080i60 in order to slow it down to 40%. I’m planning on editing in Apple ProRes 422 or ProRes 422 LT. What is the best workflow for converting the 1080i60 stuff to 1080p24 slow mo?
Shane has done a tutorial on doing this with DVCPro but I haven’t found anything about HDV. Should I capture it in a separate 60i project (it’s on separate tapes), slow it down there and then bring it into my 24P project? Or am I just not getting this? My understanding is that if I just drop it into the 24p timeline it stays interlaced, no? I’m using FCP7. delivery will be on standard DVD. Thanks.

I think that our best option is to convert it to p60.
Then Conform to p24.
This would make the footage slow down to a 40%.
I don’t know how Compressor will do this. I’ve never tried.
I case Compressor won’t do it well I would try Revision FieldsKit in AE.

Thanks, I’ll give Compressor a try…at the moment my camera doesn’t want to talk to my computer (happens a lot) so it may take me some time, but I’ll post my results.

I don’t think I have this yet. Compressor happily transcoded a clip to 24 FPS (23.98 was not an option) and progressive, but when I drop it into my 23.98 sequence it plays back at normal speed. I can slow it down with FCP and it looks better than when I slow the clip down to 40% from the 1080i60 original, but there’s still a lot of ghosting.
Obviously Compressor thinks I want it full speed, maybe there’s a setting I’m missing.
Addendum: of course I didn’t think to change the duration in Frame Controls. I’m setting that to 250% in Frame Controls and trying that now.

I didn’t manage to get what I was looking for out of Compressor, but I think I’ve got it figured out using After Effects. I am an AE neophyte, but I found good instructions at: https://rarevision.com/v1/articles/slow_motion.php#
My first test didn’t work right, not sure why, but I decided to add one step to the process: before importing the footage into AE I use Compressor to convert it from HDV to ProRes 422 (but leave it 60i 29.97). Otherwise I followed these instructions precisely and the test looks good back in FCP, hope it continues to work as I’ve got a lot of this footage.

Hi Jef,
What you have to do with Compressor is just to convert your i60 in p60.
You have to get the p24 (p29’98) by confoming these p60 in CinemaTools.
