Recording to disk

[SJ_Lee]

Hello everyone,

First, I’d like to say that I’m been reading the forums and have gained quite a bit of informative information about this camcorder and would like to thank the community.

This question involved the camcorder’s ability to record video onto the computer hard-disk via the Firewire cable. I would like to know how this process is done. Particularly, I would like to know if the camera has the ability to bypass the DV encoding process to tape, and write uncompressed video to HD. Does the disk bandwidth hinder this from happening?

If I was designing a camcorder that allowed a direct output to disk, I would allow the user to bypass the DV encoding process, but that’s me.

As you people can guess, my main concern is image degradation. I do not have the own camera yet, so I have no clue whether this can be done, and if it can, then how it is done. I’d appreciated it if someone can clear this up.

Thanks

Re: Recording to disk

I am in the same boat you are in. I really appreciate all the info people have been giving out. This is a great website and I have learned a lot here.

I am trying to figure out the best way to record straight to disk. I am planning on getting a laptop and recoding straight to it. As much as I like your idea of bypassing the compression and would really like to do it myself, I am doubtful Panasonic allows it.

I am also planning on recording the audio separately because I have the pal version and am going to have major audio issues and have so much work ahead of me anyway, I might as well get 24bit audio in the process. My question is what capture programs I can use that won't bog down a laptop. Also, would it be wise to run a video capture and an audio capture on the same laptop. My NLE is premier and it almost shuts down computers single-handedly. I won't edit on the laptop though. I will use a fast desktop.

Nope. Compression is done in the camera. The firewire signal is compressed data. You can't get an uncompressed signal out of the DVX100 (although someone on the dvinfo.net board claims to have hacked into his DVX and is reading the 4:4:4 uncompressed signal straight off the CCD...)

Wow Barry,
That is one hell of hack that guy is doing...if it is for real. :Make a hell of a difference for Color Correction and compositing.

I am patiently waiting for one of the “senior members” or someone with knowledge to answer the questions above…I would not mind knowing how to do it myself ;D. Kind regards, Jared.

Re: Recording to disk

Jarred…I did read the “quickstream review”. Some people may want to hold of on buying it until price comes down. I would definitely like to use a Laptop in the studio instead of the tape if possible. It should be possible to use the laptop but I would like to lean from others mistakes if someone will direct us to a web page or wants to give a basic overview of how to do it….thank Jared.

Re: Recording to disk

to your laptop... all you need to do is hook up the firewire and capture in your nle.. I dont understand really what you are having a problem with.

Haha.a. I'm digging out old threads for answer...
I'm using DVX, want to capture direct to pc. Is there any settings to set on the DVX before capturing ?

How do I capture it ? just press capture in the NLE and everything is done ?

I can't speak for other NLEs, but I know the process to capture directly to computer hard disk is pretty simple in Vegas. Just set Vegas to capture like you would normally from tape and let it rip. On camera settings are whatever you want. Only limitation is the space of your harddrive. One thing I haven't tried is saving to an external drive to increase "tape" time.

For those of you unfamiliar with Vegas, for me it hits the sweet spot between being a powerful application with real depth of capabilities and learning curve that does not require years to master. You can be up and running in relatively little time, yet still learning new capabilities years down the road.

Hi, i'm interested in that too.
I own an 'old' PowerBook G4 1ghz, 1.25Gb RAM. Some expert could tell me if it's enough power to direct capture from a DVX100BE? I won't edit on the laptop, only record. Thanks to all

The original post was from years ago. This has all been accomplished. If you want the 4:4:4 non-compressed output you get an Andromeda and go straight to Mac Book and if you want firewire straight to laptop you go DV Rack, (Now called Adobe On Location after Adobe acquired the company) .

I've been using DV Rack for a number of years now and the latest version is terrific. I can't remember the last time I shot to tape.

Same for FCP. But I dont see the point other than "you wont have to recapture" later, which is useful. But the preview capture windows arent so crash hot, certainly no good for monitoring what your shooting. See Craigs post above for that.
