For several HC classes we use Sanyo SD camcorders to video record student presentations that you can then review on your own. Here are some notes on using these cards for video viewing.
The card you record on needs to be a regular size SD card, not a SDHC card. SD cards are used with many digital cameras. Mini SD cards are used in some cell phones, and SDHC are a newer larger capacity card. You need the regular SD card.
So you want a card with this logo Not this logo
Make sure your name is on your card and when you bring your card to class, it is empty so it has room on it for your speech.
I’ve only found the regular SD cards only go up to 2GB, more than that and they are always HC cards.
- Many computer are now coming with SD card readers built in. If yours doesn’t you can buy a SD card reader that allows you to put your SD card into the reader and then plug into any USB jack. So you can then use the SD card as a jump drive.
If you don’t have either of these options, there is a reader available at the front desk of the library for checkout.
- The video format the Sanyo’s record in a . mp4 video format.
To view your video you have several options:
- mp4 videos will not playback with Windows Media player
- Two free programs that will playback mp4 videos are Quicktime, Realplayer and VLC. Quicktime or Realplayer are on all public HC computers.
- When playing back with the program Quicktime” the audio and video don’t always sync up exactly. When playing back with the free program VLC Media Player, the sync is fine. This program can be downloaded for free at: http://www.videolan.org/vlc/
Sanyo C40 Notes for instructor/videographer
Sanyo C40 Camcorder Notes
- For speech class we recorded in the “standard” quality mode so we didn’t fill up the network drives as fast. In that mode you can record:
- 80 minutes with a 512 memory card (51 mb per 10 minutes)
- 158 minutes with a 1GB card 316 minutes on a 2GB card
- With the HQ “high quality” setting you can record:
- 30 minutes with a 512 memory card
- 60 minutes with a 1GB memory card
- With the Super High Quality mode
- 20 min with a 512 memory card
- 41 min with a 1GB memory card
When recording with the C40, when you press the record button, the screen flashes black and then the image appears and you see a big red camera in the upper right that then shrinks to the size of a smaller red camera. Below that you will see the counter, counting in minutes and seconds and you know you are recording. When you press the record button again to stop recording, the camera turns gray. While the camera image is gray, don’t remove the card. As soon as the camera icon disappears and you get a rectangular icon, you can remove the card. If you remove the card while the gray camera icon is showing, you will get no recording.
- For less than $10 students can get a “reader” to allow them to put their SD card in the reader and then plug into a USB jack. Then they can use the SD card as a jump drive. I will have one of those available at the front desk of the library for checkout if they don’t have one. Also many computer are now coming with SD card readers built in.
- SD cards are sold in the bookstore and elsewhere. Make students provide their own card. Several other classes will also use this system for personalized recording. Make sure your students put their names on their cards, and that they bring their cards ready to record on. If the card is full, you can’t record. Students need to bring their cards empty, or with enough room for that speech.
- The video files are stored as Qucktime movies and they should be readable by all computers. If they use the public HC computers, they will need to have headphones to hear their audio.
- When playing back with the program “Quicktime” the audio and video don’t always sync up exactly. When playing back with the free program VLC Media Player, the sync is fine. This file type
- Some new cards come unformatted and you have to follow instructions and format them
