1080p "overcrank" slow mo from the XL-H1 :)

[Barlow Elton]

This test shot is worth looking at. I shot 1080i with a slightly fast shutter speed and processed using Graeme Natress' excellent Standards Conversion FCP plug-in to turn it into a 1080 60p clip--and then I used Cinema Tools to conform the frame rate back to 24p.

I believe this stuff can actually intercut with 24F without issues. 2.5 slow mo without any kind of ugly field blending garbage.

Shot in the early evening at a friend's house. His daughter was a good sport. :)

if possible could you share your workflow with us. I've downloaded the standard conversion (demo), throwed my clip in, ended up with two and two frames exactly the same. Maybe the conversion set doesn't work in PAL.

Best result i achieved was to put the clip (108i50) into sequence with a a DVCproHD 720p50 setting, then export and the import to the original sequence. Anyway I think your clips look a lot better.

Hate to say it Barlow but the footage looks pretty stuttery. It's not too smooth in motion.

I should put up a better one. The girl jumping on the trampoline probably should've been shot with a faster shutter speed.

It's much smoother motion now.

This isn't working for me.

Works with PAL just fine. Use "G Map Frames" and it's Fields to Frames options. That does the "Barlow Effect". Email me if you need more help!

Remember to choose the "Fields to Frames HQ" option, and use a little anti-aliasing too.

The method I've used that works best is to drop the HDV 1080i clip onto an actual custom 1080 60p (59.94 fps) sequence--in your case it would be 1080 50p. From there, select the clip on the timeline (which should have a red render bar) and then add the Map Frames filter. Once you've done this you should get a prompt to drop the original clip (from your bin) into the image well in the filters tab.

Select "Fields to Frames HQ" and it's best to add a little anti-aliasing. I usually have aa at "30" out of 100, and tolerance on 40. Also, select "normal" under deinterlace methods.

Once you've done all this you should see the interlace/combed/zippered look of the 1080i footage change to a single frame that looks progressive. Render out a 1080 50p clip and then bring it into Cinema Tools and conform the frame rate to 25. You can then re-encode it to HDV for integration into a normal HDV timeline.

It's best to render the 50p intermediate clip with the QT uncompressed codec in order to avoid one extra pass of recompression.

Sorry if that's a bit complicated but that's the best I could spell it out.

I think I wrote about this in another thread (maybe I'm guilty of double posting, sorry Chris!). FCP 1080p50 doesn't have 50 FPS as editing timebase. It only have 25 fps option, and then you will end up with pairs of the same image. So to find a work around, I went over to NTSC, and throw the clip into timeline with 59.94 fps timebase. Voila! Nice Slow motion after a visit to Cinema tools!
