  1. I know what I want to capture (2hr VHS to DVD), but still not exactly sure how to get there. I have 50 or so 2 hour VHS tapes to backup to DVD. Since quality is an issue, I've decided to order the Canopus ADVC 100. I would have paid a little more for the realtime Canopus MPEG EMR in order to save time encoding directly to MPEG, but I read it would not handle Macrovision as well as the ADVC 100. Now here's my question. I thought I read about someone spending 20-30 hours encoding a 2 hour video using TMPEGEnc with an Athalon 1800 CPU.

    Is that about right ? If so, my little conversion project doesn't seem so little. Also, about how long might it take the ADVC 100 to capture a 2 hr VHS to DVD quality and encode it to MPEG using an Athalon 1800 system?

  2. To capture VHS it will take as long as the movie runs in realtime...you cannot speed up that process. Hence a 2 hr movies takes 2 hrs. As far as encoding I average about 1 1/2 time realtime.. so if I have a 2 hr movie it takes about 3 hrs to encode.

    This is capturing to AVI.... if you are able to capture straight to MPEG2 you can save the encoding time.

    Each 2 hour tape will take 2 hours to capture and most likely 3-5 hours on cbr encode,double the time for 2 pass with tmpgenc,for best quality choose avi over straight mpeg capture.

    After the capture your encoding time is more-or-less directly related to your CPU speed and the settings you use in your MPEG-2 encoder.

    CCE BASIC (aka CINEMA CRAFT ENCODER) is a good cheap MPEG-2 software encoder you can use with your VHS DV AVI captures that you will be making with the Canopus ADVC-100

    TMPGEnc Plus 2.5 is the same price more-or-less as CCE BASIC but it can be much slower ... but it is a bit easier to use.

    Assuming you will be putting more than 1 hour per DVD (and who only puts so little on a DVD) then you will want to do a 2-pass VBR encode.

    If you are doing Full D1 resolution then I suggest a MIN of 1500 to 2000 and a MAX of 8000 with an AVG of 4500 (for a 120 minute video).

    If you want to use Half D1 then try a MIN of 2000 and a MAX of 6000 with an AVG of 4500

    In fact since Half D1 tends to hit the upper limit of the bitrate around 5000kbps you might very well be able to get away with a CBR of 4500 and not do a 2-pass VBR

    Half D1 is usually enough resolution for a VHS quality video and it will encode faster than Full D1.

    As for the actual time it will take. Again it is hard to say. I have an old P3 650Mhz and a 2 hour encode doing 2-pass VBR is generally 24 hours using CCE and a noise filter for the video (which works great on the image quality but slows things down). But that is a slow computer. A faster computer ... same settings in CCE ... same source ... would be faster. No easy way really to tell how fast since there are so many variables.

    But it surely won't be anywhere near real-time !

    The MPEG PRO would have been nice. All you needed was a TBC to remove Macro, which also purifies the signal.

  6. I use mainconcept to encode, takes about 1.3 hrs on a 1.7 p4 with 512 ram. Quality is good, especially for vhs. I used an advc 100 to capture. If you're picky you may want to use tmpg or cce though I find the result comparable to the original tape.

    i capture vhs at dvd resolution and hi bitrate. i capture to mpeg2.
    with tmpegenc i remove dirty borders and cut stuff i don't want (like commercials). i reencode to svcd, to i improve the image quality by resizing to a lower resolution. this may sound bogus, but it's ok cos svcd quality is good enough for tv/vcr video. i don't use any filters or 2pass encoding, cos it takes so much time. i use a cbr of 2520.
    that takes 2 times the movie time (i have a P4 at 2 GHz).
    so: 2 hours will take me 2 hours to capture (ofcourse) and 4 hours to reencode.
