HDTV capture/edit/archive question...

[Relayer]

Can you capture HD OTA and edit it with an MPEG2 editor like Womble, then archive it to DVD?

 

[NeezyDeezy]

yeah

 

[rbV5]

Sure Can. Sounds easy don't it

It'll eat up a DVD in no time at native resolution. It makes excelent source material for DVD encoding as well.

 

[Relayer]

how many GB an hour?

 

[Janooo]

When I do 720x480 uncompressed it's 74GB/hr. Lossless huffyuv is about 3.5x smaller. I am not sure about HD though.

 

[Relayer]

DV is 12GB for 60 minutes. I guess HD would be more. so...I guess archiving an hour to a 4.7GB DVD aint happening.

 

[L00PY]

My recording of 24 tonight clocked in at around 4.4 GB. An hour of 1080i clocked in just under 8 GB. Of course if you cut out all the commercials, the file will only take 75% of the space. . .

what resolution did you capture 24 in?

24, like all FOX (and ABC) programs, is broadcast in 720p (1280x720). I assume he just did a transport stream capture (just like I did, I'm a 24 fan myself ), so it saves the digital data exactly as it arrives, with no changing of resolution or anything. FOX seems to use somewhat low bitrates (then again it is a 60fps stream from a 24fps source) - my episodes from this season have been between 2.6 and 2.8GB for a 42-44 minute capture after removing commercials and null packets.

So yes, you can sometimes (not always) capture an hour of OTA HDTV and save it to a single DVDR (especially after cutting commercials). HDTV uses MPEG2 at a maximum bitrate of 19 megabits/sec (2.375 megabytes/sec).

thanks. so, you are capturing from a set top box using firewire or something? I seriously need to read up on this stuff. i was going to wait to jump on the HDTV bandwagon, but the content that I have seen so far really looks good. I want to go the cheapie route with a PC device and view it on my 2005FPW for now.

I'm actually using a PCI HDTV tuner card (MyHD MDP-130). I don't do the premium cable thing because I don't feel like paying for it, and the national ("free") broadcast networks are good enough for me for now. You have the right idea though, one could use a set-top cable (or satellite, I guess) box with firewire output to capture HD transport streams that way, if you have the right box.

If you want to start out with an inexpensive HDTV tuner for the PC, I've generally heard good things about this one. Do you live reasonably near a large city? If so, then OTA reception shouldn't be too much of a problem. Antennaweb.org is a good site to check out, to find out where your local digital broadcast towers are, and their distances and relative directions from your location.

I was thinking of getting the FusionHDTV5 Gold and toying with BTV4 right now. I currently have a PVR150 also. I live in a fairly large city with 3 local stations within 15 miles. I did check out the antennaweb.org site for direction to point to. I guess you point to the mountains were the antennas are, not at the stations.

snapstream has a bundle with an antenna here http://store.snapstream.com/fusionhdtv-gold.html

That's a great bundle there - great antenna too, I used it for all my OTA HDTV in San Antonio for the stations within 20 miles. There was another one 35 miles away and low power that I didn't get, but that wasn't a surprise.

It sounds like you've pretty much done your homework on this...I think you'll be happy with that purchase (and HDTV in general ). Let me know if you have any more questions.

I just need to find out if the onboard video on my current system is DXVA based. (Asus w/Geforce 6150)

That is a good question, but I would assume that it is DXVA-capable...I sent my mom last week's 24 episode because she missed it, and she was able to get Nvidia Purevideo decoding (DXVA-based) even on her old Radeon 8500 video card.

Forget this one. It does not work and it won't work. Ever heard about HDCP?

HDOTA is the only thing you can enjoy recording for a reasonable price right now.

HDCP is DRM for DVI/HDMI outputs, not Firewire (which sometimes uses 5c or something like that, but some boxes have unprotected firewire outputs -- there are threads on AVS Forum about a lot of people doing exactly that to transfer HD shows off cable boxes via firewire).

 

[Janooo]

My point is that most of the content that you get from firewire is scrambled/copy protected. If it was so simple to record any HD content then why bother with HDCP?

 

[L00PY]

I captured OTA HD using my ATI HDTV Wonder + MCE.
