I’ve used FalconMedia Pro DVDs for years with zero problems.

I’ve been using TMPGEnc Video Mastering Works. The bitrate varies widely depending on program length. The new LG burner will only go down to 6x on both long running DVDs and short DVDs so the bitrate has nothing to do with it. I posted on the Nero forum and someone replied that the burn speed is determined by the firmware of the burner.

I fully understand that slower speeds are more accurate. That’s why I’ve always burned at 4x, the slowest my previous burner would write. So you’re saying I should burn even slower than 4X?
Since I cannot burn at 4x, I’m asking if 6x would be OK.

That’s what I thought. I’m wondering if my client was referring to a data DVD that contained a video file and a self-contained player that is activated by a an autorun.inf file. But I would imagine there would be all sorts of problems with the compatibility with other op systems.

It’s a consumer DVR and the owners manual doesn’t say which format but I’m guessing it’s mpg2. It has several bitrate options and I always use the highest. The quality is pretty good considering it’s SD. A friend of mine makes a good living taping conferences and uses a pair of DVRs to tape long seminars. The DVRs have built-in DVD burners so when he’s finished, he makes his DVD master right from the DVR. He then takes that DVD and uses it as a master in a DVD burning tower so attendees can purchase and receive copies shortly after each seminar. For these kinds of applications where a quick turnaround takes priority over HD quality, it’s an efficient and reliable system. The DVRs can hold 18+ hours of video in the highest quality.

Gerry,
We already have a digital in-house back-up system in place similar to what you described. The back-up referred to in this thread is a back-up that takes place in the field while an event is being recorded. It would probably be more accurate to call this dual recording. For our particular needs, the client wants SD DVDs. So having the SD DVR record an anamorphic wide screen SD image out of the 150 will work for us in the unlikely event that we would need to use it. Even though the quality won’t be as good, it will be more than acceptable for our client’s project… and as they say… it would be better than nothing. The DVR is simple to operate and is pretty much bullet-proof. Now if we ever tape important events that will end up on BRD or broadcast HD, we would need some kind of dual digital recording in the field.
After reading some of the horror stories about HMC150 card problems, I can’t imagine any professional recording a live event without some kind of dual recording. I know my clients would not accept “a bad SDHC card” as an excuse. Having said that, I suspect a lot of the SDHC card problems are caused by operator error, not reformtatting and people using cheap cards.

Here’s the answer… in either camera or playback mode you can output to the composite and component jacks a downconverted 4:3 signal that can be either side cropped, letterboxed or squeezed.
-
I’ve been in the business for 27 years and have never considered taping an important event without some kind of back-up. I’m sure that recording to SDHC cards is more reliable than tape, but unless it’s 100% guaranteed, we’re using some kind of back-up. I know a Panasonic engineer that I don’t like to contact unless I absolutely have to… I’ll report back what he says.

We have used a DVR as a backup for years and it’s perfect for our needs. From time to time I videotape events where there is no editing needed and having a DVR as a backup has proven to be the right path for us. We have one client who has three 2.5 hour events with no intermissions in one day. As long as we’re taping in SD, we have a simple, bullet-proof back-up that can handle up to ten hours of back-up storage at a time. Perhaps someone else on this forum has tried what I’m asking about. My DVR is a simple, SD DVR with composite and S inputs.

Thanks for the info. That’s what I want to do… preview the clips without using the camera, decide which clips I want to use and then transfer only those clips to a hard drive.
Just curious… when you transfer the clips to your computer, how many folders and/or files are there for each individual clip?
