Rockin' Rig

Hey gang-

Here's my setup:

-HD100
-Formatt Matte Box
-Focus Enhancements FS-4 Pro 40 gig with the HDV upgrade & field kit

I'm running tape and direct-to-disk with the FS-4. After shooting I link the FS-4 to my Mac G5, copy the file to a big internal HDD, then use HDVxDV to convert it to a DVCPROHD file at 24fps. Then I import into FCP5 and go from there. I then put the tape away as backup.

Rockin'. I highly recommend it.

+Steve

Very good Steve. Are you having to deal with timecode issues or do you not need timecode to be accurate to the camera's recorded TC?

Steven,

I'm very interested to see what the 720P24 m2t recorded to the FS-4 actually looks like. Is is 59.94 fps or 23.98? Does the TC retain base 60fps properties?

Could you roll a few seconds and post it for us?

I was supposed to receive the FS-4 last week, but it hasn't arrived yet.

THe big question is: Does the FS-4 PRO with HDV upgrade have the talkback capabilities of the JVC OEM version?

Also, does your Formatt matte box use a screw-in 82mm adapter, or clamp-on 85mm ring? I still looking for a suitable light-weight two-stage 4x4 matte box. I already have the Cavision, but it is too heavy for stedicam work.

At this point I'm still experimenting, but I'm planning on relying on the FS-4 for clips imported into my computer. I believe there's a way to sync the camera's time code with the FS-4's, yes?

After transcoding the m2t stream into DVCPROHD the output footage is actually 24fps, not 23.98.

I'll see if I can find something pretty and send it over.

Not sure what you mean by talkback. The FS-4 I have will start/stop with the camera's record button. I'm going to check on the timecode sync issue.

I got the 82mm screw-in adapter. It took about a month to get from B&H (backordered), but they should have a few now. The Formatt is very light, very strong, and best of all, looks kickin'. The French Flag is a bit huge, though.

This can be easily fixed by using Cinema Tools to Batch Conform the 24fps clips to 23.98. It takes about 2 seconds to do.

With the JVC version (DR-HD100) "you can monitor the DR-HD100 time code and disk space remaining in the viewfinder. You can preview clips in the GY-HD100's viewfinder or LCD monitor using the DR-HD100's playback mode."

I'd even be happy with a couple seconds of footage shot with the lens cap on! I just want to analyze how the FS-4 handles the TC in 720P24 mode.

I'm puzzled. I'm using those 24fps clips (not conformed to 23.98) in a 23.98 FCP sequence, and they drop in fine with no rendering. Is it possible that FCP reports the clips as being 24fps when in reality they are 23.98?

Quicktime makes the distinction between the two, but I would guess that Final Cut pretty much has to treat them the same. In order for Final Cut to preview out to video, it has to treat a 24fps clip like it was 23.976, if it does not want to be dropping a frame every couple minutes.

So in other words, Final Cut probably just has an internal rule to play 24fps clips at 1:1 on a 23.98 timeline, therefore sidestepping all sorts of potential weirdness.
