Getting Nice Slo Mo: 60p clips on a 30p timeline

I recently rented an HMC150 and converted the files to MPG2 via Upshift. It seems to recognize the two different shoot settings: 60p for the action stuff and 30p for everything else.

I am thinking I need to create a 30p timeline, and drag a 60p clip in, then set the speed to 50% and drag out the tail. But it's not working as I hoped. The footage plays a frame, holds that frame, then changes to the next frame... as if the footage was 30p on a 30p timeline stretched to 50% speed.

My hope is that the extra frames would just show up, by advancing the timeline cursor a frame at a time I would get unique frames, but that doesn't seem to be the case.

Someone suggested creating a 60i timeline and rendering it out at 60i, then bringing the clips back into a 30p timeline, but that's going to be a lot of clips and blow away my planned workflow.

if it's really 60fps, make sure that the media properties say 60 fps. If it's set to 30 it will play at 1/2 speed by default & stretching it out more will cause the stutter you're seeing.

The property of the clip reports back 60p (actually 59.940 double NTSC).

Sorry guys, it didn't work last night but after a reboot and using the paid-for version of Upshift the slowmo works as I hoped!

I suspect the demo version may not be totally the most current version in addition to having a 10 second limit.

This HMC 150 60P footage looks FREAKING AMAZING!!!

Indeed! I second your excitement. I have the same camera, PAL version, which is HMC 151.

What I do, I use only Vegas. I record 1280x720 50p. Then I add the clip I just recorded to the Vegas timeline. Then I right-clikc, select properties and set the playback rate to 0.500 or even 0.250.
Even at 0.250 the slow motion is beautiful, at least with a shutter speed of 1/2000, which is no prob in bright daylight.
Add the Sony Vegas Sharpen FX with all settings to zero(it still sharpens) and you have an incredible slow motion at super quality.
Amazing? Yes!!
