  1. I hope this is in the right place, and apologies if it's a subject that's been covered before.. I've recently had a regular stream of staff approaching me with the simple-to-say comment 'I want to make a video in class' at which point my heart sinks as I know that it's never that simple! I've yet to work out a good, simple, robust way for staff to record in the classroom and edit the results to a final video for playback to the group in the enxt lesson. Just curious what solutions others have come up with for a simple workflow from shooting trough editing to showing..? At the moment we have two ways of working: DV tape camcorder or more recently these new Flip Video camera things that plug straight into a USB socket. Obviously the DV tape solution, whilst far superior in terms of video quality, is a lot more involved in terms of capturing the footage onto the computer, and in practical terms, to make things easier, capturing is best done with a DV Firewire card that we have installed into a selection of computers in the ICT areas, but of course this limits where they can actually do the capturing. Once captured though (using Windows Media Encoder with a preset configuration file setting the correct video and audio sources) the resulting WMV is of a reasonable size and can be edited in Movie Maker. The Flip camera solution appears to be FAR simpler in terms of capturing, being simple plug in and drag off via USB, but at the sacrifice of image and sound quality. It's also slightly less efficient with file sizes as the copying process will be less discrimitaing than the realtime capture process of DV. The teachers will inevitably just copy the whole lot across and not think about only copying over what they actually need. However, the teacher can upload and play/edit the recorded video files pretty much immediately, and from pretty much any computer in school now that we have rolled out the codec. We've recently acquired a couple of new Sony DCR-HC62 Handycams that appear on paper to be the best of both worlds - record good quality to DV tape but then plug in through USB to stream and capture the footage onto the network using Windows Media Encoder. This system falls down though when actually trying to capture - although I've got the codec installed and can see the video preview playing back in WME, as soon as I hit capture the screen goes black and no video is captured. Now this may be a configuration/driver/codec issue but it will take time to fix and I'm deciding which path to persue.. This system, if it works, also has the benefit of being able to work anywhere that has USB (albeit still needing the install a codec/driver) as opposed to having to install Firewire cards all over the place. So, do I stick to trying to get the Sony cameras to capture via USB properly, do I stick to the relatively limiting but tried-and-tested Firewire capture or do I go with the Flip video cameras which are pretty much idiot-proof but sacrifice a bit of picture and sound quality, and unfortunately, maybe allow the new DV cameras sit around doing nothing as nobody knows how to use them. More generally, out of interest, how much IT support time does everyone give to this sort of thing? Is it even an IT support thing at all? We have a new IT/Multimedia post being filled pretty soon so I guess that's the person to be doing these sort of tasks. Would you consider it reasonable for the teachers to do the shooting, for us to then capture and make said footage available for them or should the capturing be something that the teachers do themselves..? The worse case, and that's happening more often, is the request that starts 'I've got some kids that have filmed something for me at home...' and of course I have no idea how it's been captured, whether it's on DV, Memory card or HDD (usually .mod files) and again, should this be my problem to fix..? So again, just curious what solutions other places have come up with for this growing area of teaching resources. Questions questions questions... (sorry!)
  2. Okay, we're going for the plan of changing to static IPs to see if that helps the situation. We've set half the cabinet to static and left half as DHCP and hope to find that any more failures are from #16 upwards. Slight side issue with doing this, setting the IP to static breaks the ISA Firewall Client as it uses the WPAD data as sent out with DHCP to identify and connect to the proxy. The way around this we found is to configure DNS to include a mapping for WPAD so that the static computers can now find the proxy directly.
  3. Sorry to hijack this thread, but it looks remarkably similar to one that I was about to post myself.. We have a trolley of 30 netbooks which generally work absolutely fine, albeit after adding a second access point to get all 30 connected at once (3Com left that little detail out of the small-print!) Recently though, we've found that they will randomly refuse to connect to the domain and thus the users cannot log on. We have also found that simply rebooting once whilst hard-wired fixes whatever is broken and the wireless starts connecting again and authenticating users logons. We've not really got enough data as yet to find any patterns, but gut-feeling is something timing out after a certain time. Signal strength is fine as the block it pretty well covered, and it's certainly not affecting all of the netbooks. Of the 30, we've had maybe 8-10 'break' in total, whilst the remaining ones have worked throughout. We're going to try the suggestions above of setting static IPs to see if that helps. We have tried setting a 'broken' one to a static IP and it has NOT started working, but there's a thought that maybe having a static IP will stop it from breaking in the first place. The time to failure seems to be in to order of 20-30 days, so unfortunately, we probably won't know if any fixes have worked immedaitely. Any other thoughts or suggestions would be gratefully recieved!! Chris
