live recording from handycam to prerecorded dvd?

[Matemago]

i’m gonna do some tests as you say… can you recommend me a wireless transmiter for the camera? my distance between tower and lobby are about 80m.

thanks

Try this: https://www.geeks.com/details.asp?invtid=MINI-WIRELESS&cpc=SCH&srm=0

It doesn’t have firewire output, but it should be good enough for testing purposes, due to its price. But, if you want to spend more $$, call up B&H and they will gladly reccomend a few itmes.

ok, my main problem is with session finalizing time. it has to be less than 5min… what if i use dvd-rw? it finalizes faster right? can a dvd-rw be prerecorded with our promo and then just put that disc on a dvd recorder to add your jump video stream?

Hi matemago

You need to finalize the 2 together unless maybe you want to invest in that $5000 recorder. DVD-RW makes no difference on time. What about doing the work on a laptop at the top of the tower? You could press play on the camera, the clip appear on your desktop, then drop it into you authoring app.

The only real solution I see hear is to use a simple authoring app like DVDit. The only problem lies in how and how fast that clip from the camera can get onto a computer HDD the fastest.

that seems to be the solution. having a 5,000 recorder exposed 24×7 to seabreeze is not an option.

so as you say, there is no difference if i send to prerecord my dvd-r’s ? just with the promo part inside, leaving the dvd session open so i can just add the jump video part? same as me burning the two parts from a project residing on a laptop for example?

Hmm…I am going to try this out with something of the same duration. 5 minutes shouldn’t be a problem at all. Let me give it a shot this weekend and I will report back.

You really cant “pre-record” a DVD. It either contains a VIDEO_TS folder or it does not. That Pioneer deck will “hold” your promo for you until you send it the next persons jump and press “finalize”. At this point it will mux the DVD.

Another thing to consider is that you want to show the person thier jump when the adrenaline is flowing 🙂 An AVI or mov. clip from a camera source that can be easliy accessed is a great way of doing this. If they like it – pop it in the authoring app and burn.

Hopefully Aanarav’s test can shed some light

I really wanted to try this out, so I spent the better part of the night testing this:

I took a random 30 minute clip and using Premiere Pro’s encoder, exported it as MPEG2. This 30 minute clip is the equivalent of your promo. It took me around 100 minutes to do this.

I then created an Encore project with the opening menus and with the encoded MPEG2 file.

Then, I setup a camera and by using ScLive (https://www.scenalyzer.com) I started capturing 2 minute segments.

Imported a single 2 minute segment into Encore DVD and it took 12 minutes to encode and burn. HOWEVER, I was using 16x DVDs. This is almost double the time of what you are looking for. Therefore, if you can find a way of capturing the file as an MPEG2 clip, such that you don’t have to wait for it to encode, you can reduce the time by almost 4 minutes. I don’t have the ability to capture MPEG2 source files, but I **think** Sorenson Squeeze does have that feature.

I like Eric’s idea though. Burn the disc only if the customer is interested. Capture the footage as AVI, show it to them and if they like it, burn it to a disc. Once you know that they are interested in clip, I am sure they wouldn’t mind waiting a few minutes.

Here’s a cut/paste of my reply to the OP in another forum where the same question was posted. Near the end it has a suggestion for capturing the dvd compliant mpeg2 in realtime (saving any render time)

<<< My standalone LiteOn DVD Recorder can record a live video feed from my camcorder. For instance, say I have my camcorder connected via firewire to the dvd recorder. I can turn on the camcorder to record, and then hit record on the dvd recorder to capture the live video from the camcorder (I don't have to be recording on the camcorder). I can also hit record on the camcorder to be recording to camcorder tape and simultaneously recording the video to dvd recorder (in case you need a backup). You would have to have the dvd's pre-recorded with the intro video, then load a new one up for each jump. How much time before the next jump do you have? The issue might be the loadup time, and the finalize time (if you use DVD+RW discs you might be able to skip the finalizing time). Perhaps two dvd recorders (and an extra person for help). Then as you are doing one person, you could start the load process for the next person using the 2nd dvd recorder? Another approach would be to have a laptop/computer in the field. Have a project pre-authored so that all you have to do is drop in a compliant dvd video, compile and burn to dvd
