for those of you with digital camcorders

[statuspending]

correct me if im wrong, but if you have a digital camcorder, then don't you have a really good capture solution?

wouldn't you just have to use the line inputs from your source, and the camera will record to mpeg1 or 2?

then use a firewire connection to get it to your computer and start those vcds on fire!



this is hardcore

[bigbear]

I have a Sony TRV-330 that has composite & s-video in with stereo audio in and dv in/out. It's a very nice camcorder. I use it as a pass-thru from VHS sources with a SIMA color corrector pro in between (some of my source has pinkish flesh tones, dropouts in the tape itself & other color anomalies). It tends to save me some time in the encoding process (I do not have to do as much filtering with tmpgenc).

You have an excellent capture solution, but it doesn't convert to MPEG on the fly for you. It captures in a format that uses 3.6MB/sec. 1 hour of video = 12.6GB of drive space. 2 hours=25.2 GB and so on.

When I take VHS source and capture it as 1 huge AVI file in win2k, I find that the audio drifts out of sync over time. The drift seems to be constant.

I wind up capturing in Linux with a utility called dvgrab. It chunks the files up into 1GB (about 5 minute) segments. I then run these into tmpgeng, concatenate the finished files, and then I have VCD/SVCD.

But the 1 issue I have with that is tmpgenc (at least with beta 12f) is hearing a clicking or small screeching sound where the finished MPG files join. I've not tried 12h yet to see if this problem has gone away.

So, I was wondering if anyone knows a solution to either of the 2 issues I have:

- does 12h fix the audio stuff, and
- is there any way to keep audio/video in sync with *long* avi captures?

I actually capture in 15 min segments and encode with TMPG 12a. Then, I tell 12a to "chop" it at a scene change. After chopping, I join them together and it doesn't produce a screech (at least for me).

Thanks braindrain, I'll give that one a try!

miniDV and DV cameras don't encode the video to MPEG-1 or 2. Rather, it is encoded to a form of MJPEG (motion-JPEG) I believe.

After transfer through firewire, you will still have to convert it to MPEG-1 or 2.

that's bull#&@$

heh.... guess i won't be buying a camcorder for a while then =)


THIS IS HARDCORE

[hitechjunkie]

miniDV video compression is I-MPEG (all I frames!!), weird!!

Ah... so that's what it is.

[hitechjunkie]

or maybe it's DV codec dependent...

[hitechjunkie]

then there's type I and type II - don't really know what the difference is though...

Big Bear,
I had the same audible tone when joining mpeg's in tmpg using the cut join method. Try Frame Serving your mpeg segments from Vdub (thats the one I use and am most familiar with) to Tmpg. I have had great results, no tones

Bigbear, you can do conversion DV->mpeg1/2 on-the-fly
real time with mediostream's codec and InterVideo's WinCoder.

[ToddB]

Is there a trial version of this mediostream software? I went to thier web site and saw it with the firewire card for $250.

how do you load more than one MPEG segment into VDub? i tried doing this yesterday and after loading the first, the "append segment" was not available.

my original reply (see message #2) was a bit misleading. i actually capture *avi* files & then process them in tmpgenc. i may have made it sound like i pushed mpg segments as input.

i don't think vdub can use mpg as input but i've used it for a whole 10 mins now, so i'm no expert

Mark W.,

Seems to have worked like a charm for me. This is awesome. Now I can go ahead & convert my videotapes. Now I just have to get my SVCD's to play at a normal res on my Pioneer DVC302d, and life will be good.
