XDcamHD 350

As Nate pointed out, the minimum 2-sec clip is only created if you stop the interval recording process before enough frames to create a 2-sec runtime are collected.

For example, if you are operating in the 24p mode and start an interval recording process and collect only 24 frames and then stop the recording, a 2-second clip will be recorded that when played will display the 24 interval frames and then show 24 realtime frames.

Great info Nate! One little thing the camera can’t down convert via firewire can it? I haven’t been able to make that happen.

Now all is clear -I think, thanks guys.

So going back to my original question, I’ll likely be able to force a stop frame animation sequence providing I collect enough frames to satisfy the gop thing. Blimey it gets complicated doesn’t it? Hmmm no powering down the unit in this process then.

Also too I guess I must make sure that after the animation sequence I expose at least another 12 frames to ensure that the gop is complete.

Any answers to the question of whether the P350 will down convert and output to firewire? I must admit that I’d rather taken it for granted that it would do that.

Thanks

Alan, the camera does downconvert to a DV stream on the firewire port if you want it to. You choose whether you want the firewire port to be in AV/C mode (sending a DV stream out), or FAM mode, where you plug the cam into a computer and it shows up as a mass storage device.

In AV/C mode you can also capture HD like it was a DV camera, with deck control.

I’ve ALSO shot HD, and captured via HD-SDI into my Decklink card, while using the FW port in DV mode. This gave me deck control and timecode. Follow? I had to do this to get some 30P @25mbit into my computer (the one mode that’s not supported on the Mac).

I think you’re going to be out of luck on your animation desires…I’m racking my brain and I can’t think of a way you’re going to be able to do this unless you choose a fixed interval and use time lapse.

For the price of a Sony 90wh lithium battery you can buy a Canon Digital Rebel and get a superior animation camera!

>I’ll likely be able to force a stop frame animation sequence providing I collect enough frames to satisfy the gop thing. Blimey it gets complicated doesn’t it? Hmmm no powering down the unit in this process then.< Although it may be related to GOP functioning, the situation is really determined by collecting, for the frame rate mode in use, collecting enough frames before stopping the interval recording process to complete 2 seconds of realtime playback. >Also too I guess I must make sure that after the animation sequence I expose at least another 12 frames to ensure that the gop is complete.< No, that's not true. For example, if you're in the 24p mode you just need to capture 48 frames and that will fill up the 2-sec clip time precisely. If you're in the 60i mode you would need to collect a minimum of 60 frames. >Any answers to the question of whether the P350 will down convert and output to firewire?< The F330/F350 will output downconverted DV-format video via Firewire in both realtime and from disk playback.

>I haven’t been able to make that happen.< Do you have "i.Link MODE" (page O10 OUTPUT) set to "AV/C", Dave? Carroll Lam

[Alan Lacey]

thanks guys that’s clear now.

I’ll check out the Canon Digital Rebel Nate.

In Timelapse mode every single frame is an I-frame and GoPs don’t come into it. In Timelapse it also goes into standby mode using hardly any power.

You can downconvert via FireWire. Just set it in menus to AV/C mode, which is should be in by default.

[Alan Lacey]

Surely gops have got to come into it at some stage Nigel, the output format is mpeg2.

Alan

[Nigel Cooper]

yes, just not at the recording stage; don’t ask me how it works after this.
