need DV time shifting howto
Hello Folks,
perhaps you can help me on the following task. I have: Panasonic NV-GS150 Some Samsung Laptop with ~2 GB free HD. Linux and Windows - on both OS Firewire capture works. I can capture and playback, live or from generated files. I want to time shift the live capture some 60 seconds without stop and playback all the time. It is intended for training. People have to perform an action and then may look at themselfs and perform same action (hopefully better) again. I thought about looping over two or three different files (like logrotate) but there should be an easy way for my task. As i am quite new to this i guess i just don't see how. Thanks in advance, Ingo |
The easiest way to do this is with a Panasonic DVD recorder with Hard drive or DVD-RAM. The DMR-ES15 will do the trick for you. Plug your iLink cable( or analogue input) into the DVD recorder, start the recorder on a 2 hour encode, when it has gone the 60 sec, use the "time slip" feature to go back 60 secs and it will carry on playing/recording until you stop.

Do you have a second DV device? If so, I can provide a program that will simply stream the DV from your Panasonic, via your computer, to the second DV device. For the first 60 seconds, the stream will be live, after that it will be delayed 60 seconds. If you don't have a second DV device, how are you planning to display the delayed video (on the computer?) It uses RAM for buffering - you need at least approx. 200MB to hold the 60 seconds of video. 512MB total RAM minimum should be OK. Thanks, John. |

Instead of writing to another DV device displaying it should be no problem for your program (?). On hardware side i got 1gb memory. That should do it. I would like to try it. What OS do i need? ==== Quote:

Hello,
I can easily add the option to display on the screen. Windows XP SP1 required. Will the delay always be the same - i.e., one minute? John. |
any hard coded time (60s) will do. An option to adjust in a range of 10-60s (120 critical on memory i guess) would be great ofc.
