question on older Pioneer 533H model

post #1 of 6
Thread Starter 
it has the hard drive.

1. if I record to the hard drive what does it record to...avi, dv or what format?

2. if I edit on the hard drive and then burn to dvd is there any loss in quality, and is it still first generation, just as if i had burned straight to dvd from the satellite box to start with? Or is it a second generation?

3. is there a way to export it to computer, and if so, how?

My biggest concern is if I record a show straight to dvd, then it is first generation. if I record to hard drive first, if it records to dv format then when I go to computer or dvd then it is already digital so there is no loss anyway. if it is avi or something else then there must be an encode process somewhere which then takes a littl bit from it.

any answers would be helpful..thanks..t

DVD-Compliant MPEG2 is the video format all DVD Recorders use to record. This is the only video format that complies with the DVD Standards and therefore can be played back on "any" DVD Player. The encoding you refer to happens prior to the video being written to the hard drive. It is not DV. DV is ~25Mb/s (13GB/hour), that would eat up a 80GB drive with just 6 hours of video. DVD-Compliant MPEG2 runs bitrates in the range of 2Mb/s to 9Mb/s (approximately).

When you High-Speed Copy a Title on the HDD to DVD, that is a lossless copy. A Real-Time Copy does introduce a second encoding however.

To transfer such video to a PC, simply take the Finalized DVD out and put it in the PC's DVD drive.

(I have the 633 model by the way.)

hi Bob and thanks.

so if i understand this right....recording to the HDD, and then high speed copy to a dvd is exactly the same thing and quality as recording straight to dvd from the satellite box then right?

I really would like to use my hdd on my 533...but have hesitated because I was afraid that to put it on dvd from hdd would lose a little.

I understand about mpeg2 and all that mostly.

which to me and I could be wrong, and correct me if i am, then it records to the hdd in a video_ts and audio_ts folder vob files and the high speed burn just burns that to the dvd? thanks..

One other thing...if I say, edit out commercials wil it reencode it prior to high speed burn or just connect the segments and burn with no loss?...t

Like I said, a High-Speed Copy produces a lossless (exact) copy of the original. Even if you have made edits to the Title on the HDD prior to the copy. There is one consequence of using High-Speed Copy on an edited Title and that is that the cuts you made during editing must be moved to the nearest GOP boundary (every half second). Due to the temporal (inter-frame) nature of MPEG encoding, GOPs (Group of Pictures) cannot be divided and still retain the integrity of the encoded information. This is why the recorder gives you the option of "Compatible Mode" or "Frame Accurate" editing, the former restricts cut points to GOP boundaries.

The VIDEO_TS/AUDIO_TS folders are artifacts of the Finalization process. When you do a High-Speed Copy you are copying the equivalent of the VOB files, basically wrappers around MPEG2 and audio streams. Those details don't really matter though, as long as your applications know how to get the audio/video off of a Finalized disc. The applications care about that stuff so we don't have to.

The file structure on the hard drive is proprietary and does not necessarily include VIDEO_TS, etc. folders. What happens on the hard drive is a "black box" that you really don't need to worry about. All you really need to know is that if you make a recording on the hard drive you can easily copy it to a DVD, and if you do so in "Video" mode (as opposed to VR Mode) you'll get a standards-compliant DVD that should play on any player. Since standards-compliant DVDs must have VIDEO_TS, etc. folders, that's what the DVD copy will contain.
