Getting good 24p out an old JVC HD GY-HD10U.....yup possible at DVinfo.net

Are you like me and only shoot 24p? Have an old JVC GY-HD10u that only shoots 30p? Don't throw away that 10 year old JVC GY-HD10U just yet.....

Call me a glutton for punishment, nostalgic or just plain cheap. Any are probably true. After I wrote out for myself how to get get good 24p slow motion from JVC HD-1/10/100/110 cameras with HDV SDHD 60p imported into final cut pro to make decent slow motion video....

I thought why not decent 24p would be similar process just no cinema tools to slow it down and retime it. In otherwords take the 24p from a 60fps 480p SDHDV source, not the 720p 30p HDVsource. The 960x480p 60fps is not as good as the 1280 x 720p 60fps that the JVC HD200/250/HM-100/700 series camera are, but I don't have one of those and I would like to have a 2nd 24p camera to use with my JVC HD110 on multi camera shoots that use 24p with a similar color palet.... In other words I have a JVC HD-10u sitting on the shelf.

Now I know you can shoot 30p and export it to 24p, but to get good results with motion and frame rate conversion the render time is enormous. 24:1 or longer. My 8 core mac took over 24 hours to convert an hour of footage from 30p to 24p with all the motion compensation on Max. Result was good, but nothing is worth waiting that long. Cheaper to go buy a new HM100 at that rate than wast that amount of time converting older technology footage. This method is only slightly longer than real time on my mac.

1. OK shoot SD HDV 480p 60fps... DUH... on a JVC HD 1/10/100/110 (obviously there is no reason to do this on a JVC HD100/110, but you could if you wanted too....)
2. Capture via iMovie.
3. open up your clip in your Quick Time Pro.
4. Export out of Quick Time Pro the clip as a quicktime movie 720p 24fps HDV.
5. Import the new clip into your new 24p 720p HDV timeline in Final cut pro and it should look pretty good next to your normal 24fps 720p footage...

The results really don't look bad and it doesn't take too much time. Not as good as a 2nd JVC HD110 or a new HM-100 as a B camera, but the motion is a lot more believeable than just a 30p to 24p conversion, and if you got a older JVC GY-HD 1 or GY-HD10 laying around, you can make it do 24p in Apple's Final Cut Studio without too much of a head ache.

You can also just drop 60p footage into a 24p sequence in FCP and it will throw away the extra frames. Ingesting 480p60 is always the issue though. Can iMovie do it now and keep it in 480p60?

This is a good tip. There's been a lot of talk about 30p to 24p over in the Canon 5D Mark II forum. It's amazing how long it actually take to process that particular frame conversion.

Tim, seems to be progressive. I-movie 08 (7.1.4). (Also I'm running Apple's FCP Studio 1.... haven't upgraded so my FCP can't read the AIC captured by iMovie)

Don't really know much else about it, this is the most i've used iMovie to be honest..... scrubbing frame by frame.... Looks progressive, though it might be deinterlacing on the fly in the viewer.

Regardless the results come out better than a simple (fast) 30p to 24p conversion or a 480i 60i upconversion to 720p 24p ever looked. I guess I can keep my old JVC HD10 a little longer at this rate. Though I would like a HM100 and HM700 and make my HD110 a B-Camera.
