    Notice to Powerbook Duo Users!

    I feel like a complete dufus. It's been a while since I've posted anything on bulletin boards, and now I've managed to do it wrong. I messed up the italics BBCode in my previous post and now phpBB won't let me edit the post to make the correction. Very frustrating. I must be missing...

    Notice to Powerbook Duo Users!

    Thanks for the info about problematic caps. I've got a Duo 280c that needs inspection for this problem. The full Dock had the clicking problem a long time ago, but I never replaced the PSU caps. I did not think it was an operation I could handle myself. More recently, I recapped the PSU in...

    Newer codecs on OS 9?

    For playback of your own video footage on a nice display, you will want something other than regular DV. DV would work fine if you were playing it through a MiniDV Camcorder to a TV, but the DV format defaults to low-quality for Quicktime playback. Encode it with Apple's MPEG-4, or 3ivx, or...

    GarageBand, Guitar Amps on a G3

    Hi, Jim. I'm glad you enjoyed the article. Yes indeed, I have been running GB2 on my Pismo 500. I recently upgraded the internal drive to a 100GB Western Digital Scorpio, and that seemed to make a nice speed improvement in overal system performance. I am also now running Tiger. The Pismo...

    Networking a Powerbook Duo: serial -> OS X/unix -> internet

    I've only done a direct serial connection with a terminal program like Z-Term or the Communications mode of ClarisWorks. In that situation, you'd need to select Null Modem Cable from the list of modems. If you are using PPP, then you would also have to select Null Modem Cable. The "server"...

    Video on PPC Macs

    I don't have any experience with HDV, but I think it uses the same 25Mbps data rate as regular DV. The trouble with HDV is that it uses heavier MPEG compression instead of the simpler compression used in DV. I have had success capturing and editing DV with iMovie 1 (2?) on a Powermac 8500/120...

    Video on PPC Macs

    The accepted desktop video resolutions have been NTSC at 640x480 or PAL at 768x576. Other resolutions simply divided one (or both) of the dimensions in half to reduce data size. Television standards do not have a resolution of 800x600. Your computer would have to create extra pixels. The...

    Networking a Powerbook Duo: serial -> OS X/unix -> internet

    Congrats on getting the Duo on the net. That is a rather clever solution. Perhaps it isn't as fast as ethernet, but it could still be quite fast. Back when I first got DSL (and before hardware routers were affordable), I ran IPNetRouter on my Quadra 840av to share the DSL between several Macs...

    Watching a Wallstreet Battery Die

    From what I can surmise from this discossion about Li-Ion batteries, there are the cells, which can have between 0-100% charge, and then there is the circuitry that allows something like a 10-100% charge. (I'm just guessing that 10% might be the safe bottom figure here, as TomLee mentioned that...

    MP4/MPEG to MOV converters that can handle any color depth

    I just created a new thread for the Cinepak vs. Motion-JPEG discussion, since it seems better categorized as a Software topic. > http://68kmla.org/forums/viewtopic.php?p=11816 John

    Cinepak vs. Motion-JPEG

    A discussion about converting an MPEG-4 video to 4-bit Cinepak Quicktime spawned some discussion about quality of different codecs. > http://68kmla.org/forums/viewtopic.php?t=960 I thought I would start a new thread to discuss the topic of Cinepak vs. Motion-JPEG as it seems interesting to...

    MP4/MPEG to MOV converters that can handle any color depth

    I'm fairly certain that the version Apple includes in Quicktime has not changed. Apple licensed the technology from Supermac, the makers of VideoSpigot capture cards. I guess Supermac was aquired by Radius, which subsequently went out of business. At some point CTI must have purchased the...

    MP4/MPEG to MOV converters that can handle any color depth

    I don't think the Cinepak codec has changed at all since Quicktime 2.5. MoviePlayer is just the front-end. If you use MoviePak or Cleaner, it still uses Quicktime's Cinepak encoder, but gives you some additional options for changing the video before sending it to the encoder. Some options are...

    MP4/MPEG to MOV converters that can handle any color depth

    Cinepak's motion estimation was best at camera panning, or linear motion. Things like camera zooming do not fair well with Cinepak at low data rates. Tomlee, you have gotten me curious about this strange phenomenon. I don't understand why Cinepak is performing poorly compared to Motion JPEG...

    MP4/MPEG to MOV converters that can handle any color depth

    To clear things up and avoid confusion... I am not Mark White. I did help Mark with the MpegDec project, but only in small ways -- beta testing, icon design, and web design/hosting. It's too bad MpegDec has that MP2 bug. (There were screeches and other noises in the AIFF, when I tested it...

    MP4/MPEG to MOV converters that can handle any color depth

    If you're going to do the conversion on the LC, this is the procedure: 1. Use MPEG Splitter to split the audio and video into separate files. 2. Open the video file (.m1v) with Sparkle. 3a. File>Save As... to export the video to Quicktime 3b. Set the frame rate to 10 or 15. 3c. Set the...

    MP4/MPEG to MOV converters that can handle any color depth

    Alk is correct in that 68k Macs cannot decode MPEG-1 video in real-time without a hardware decoder. There is a software decoder that allows conversion from MPEG-1 to Quicktime. It is called Sparkle. It also comes with an MPEG splitter and an MPEG-2 decoder. &gt...

    A Wallstreet Resurrection

    Great job with the repair. That Wallstreet looks to be in great condition -- it must have gotten that spill early on in its lifetime. (Or is the perfectly clean case one of those Danamania Photoshop tricks?) I have a 12-inch Wallstreet with a torn ribbon cable. The cable is for powering and...

    switching to os 9?

    pzler: The Interface speed of Mac OS 9 should feel much snappier than OS X. The drawback is that multitasking is not as refined. If it takes 30 seconds for Photoshop to launch, you have to wait the full 30 seconds in 9. In X, you can switch to another program while Photoshop launches in the...

    Imitation batteries

    I am not sure about this particular generic battery, but I've got two of the aftermarket batteries that OWC sells - a 6600mAh and a 7200mAh for my Pismo. They work very well. The 7200 I bought new, and the 6600 I just got used last week. The 6600 had not been used in a while, so I had to...
