I'm an old-time computer geek but rather new to working with computer video technology, so please pardon any obvious ignorance in my posting.
My video sources are:
- analog camcorder, 8mm tape format
- VHS videocassette recorder/player (analog)
- cable TV system tuner box (analog output)
My goals are to convert analog programming into digital format, with the ability to create either high-quality files for archiving purposes, or compact files for posting on web sites, and various steps in between.
Unlike Muldar, I have an inherent distrust of hard drives for long-term storage of anything valuable, so I hoped that backing up large video files to DVD+R -DL media would be a more secure storage method, even if some of the discs were only readable reliably in a PC.
I have reasonably powerful computer hardware -- 3GHz P4, 800 MHz FSB, 3 Gb DDR DRAM, 200 Gb SATA hard drive, dual IDE DVD-DL drives, NVidia video card, etc.
I bought a Plextor ConvertX PX-M402U external box for doing hardware encoding and compression in any of numerous formats, including MPEG-1, MPEG-2, MPEG-4, and DivX, with lots of options from highest quality (96 minutes per 4.3 Gb DVD) to highest compression (11 hours per 4.3 Gb DVD). It connects to the PC via USB2. It included both WinDVD Creator and ULead Video Studio 8 SE software.
First problem came with the software. I installed WinDVD Creator and used it a bit, and it seemed to work OK. Then I figured that the Ulead software should be more powerful, so I installed that. From that point on, the WinDVD Creator software became unable to capture any video from the PX-M402U. I tried uninstalling Ulead, tried uninstalling and re-installing WinDVD Creator, to no avail. Oh well. It looks like it's Ulead or nothing from this point onward. So, on to working with Ulead.
The capture process is pretty painless and seems to work correctly. I can select the desired capture format, click on the capture button, and everything is converted in real-time. A 2-hour VHS tape is captured in the 2 hours it takes to play it. A 2-hour TV program is captured in the 2 hours it takes for the show to air. No real shock there.
However, when I attempt to exit the program, I get a warning box pop up that tells me that my file is not saved, do I really want to quit? Well, the first time this occurred after a 2-hour session converting a VHS video tape, I could see a 2 Gb AVI file on my hard drive, but feared that it would get deleted as soon as I quit, so I told the software to create a disk file in the same encoding format. In this case, it was a DivX Home Theater High (but not Highest) quality format.
Twenty-two hours later, I had my mpg file, and it had grown to about 5 Gb (too big for a single-layer DVD disc). Hmmm.... The DivX format I was using should have taken about 977 Mb per hour of source, or less than 2 Gb, which is about where the file started but most certainly not where it ended up.
Last night, I recorded a 2-hour TV show for my own viewing at a later date. The original capture went fine, 2 hours to convert to an AVI file. Then I tried to edit this video with the Ulead video editing software. All I wanted to do was trim out about 15 seconds of junk at the front of the file and about a minute of junk at the end of the file, and keep everything in between. Took me all of about 2 or 3 minutes to make the edits, and then another
6 hours to save the result!!!!! To add insult to injury, I ended up with a 2 Gb AVI file (what was originally captured) and an 800 Mb MPG file (what it saved after the edits). Again, I told the software to use the same output format as the input format, so no re-coding should have been needed, so the file should not have taken so long to save, IMHO. Also, the specs on the DivX format I chose say it uses an average of about 977 Mb per hour, so a 2-hour show that fits into 800 Mb sounds like it was compressed to a lower quality standard than what I originally requested or how I told it to save the result.
Tonight, I tried to record a 2-hour TV show for future home viewing. Once again, the hardware-based encoding went as smooth as silk. But this file has lots of junk that I would like to edit out, like commercials and such, so I again called it into the Ulead editor to work on it. Since this would have lots of snips, I figured I'd use a built-in feature of the software to automatically break up the file into individual clips by the software's best estimate of scene changes (by the changes in the video and audio). It seems like it's making good choices of breaking points, but after 60 minutes of real-time processing, it appears to have processed only 6 minutes of source video, if I am reading the display correctly. At this rate, my 2-hour TV show will need 20 hours just to find the scene breaks, and THEN I can sift through it and throw out the parts I don't want manually. Ugghhhh!!!!!

Oh, and there's a very annoying feature (bug) in this scanning component of the software. While it's scanning for scene breaks, if you touch
any key on the keyboard, even a SHIFT key, the process stops and all the scene breaks found to that point are discarded. You have to start over at the beginning again.
There seems to be something fundamentally wrong here, or something I simply don't grok. Why on earth would it take 6 hours to trim 1-2 minutes off of a video capture file and re-save it? Is all video editing this slow and tedious?
