High Quality Capturing with Little Frame Loss in VirtualDub
Ok, this is my first attemp at a guide and I feel that it will be a helpful one.
Lets being:
your going to need some programs
·VirtualDub
·TMPGenc
Also, make sure you have defraged and closed down all unneccesary programs(i.e. anti-virus, or anything in the tray).
These are the basic programs that I will use, it is helpful to have filters for VirtualDub if you'd like to clean up your video before encoding.
Lets start by seting our resolution:
In capture mode in VirtualDub in the "Video" menu select "set custom format"
ok, once the dialog box pops up choose your format. For most captures a resolution of 352x480(or 576 for PAL) will produce very acceptable quality. For the data format choose YUY2, RGB24 is a waste of space in the eyes of many and this also helps to keep the amount of data being written to the hard drive down, this will help minimize the number of frams lost.
After you have set your capture resolution and data type its time to select a codec to save the file in.
Personally I use PicVideo MJPEG with a quality of 20, a large amout of people use huffy but PicVideo compresses better and causes less problems down the line. Go ahead and set up your PicVideo like this, it will help with better results. Since we are capturing interlaced video make sure to click the "2 Fields if more than 240 lines".
Now that we have our compressor set its time to set the audio. Most people will capture in stereo, with my capture card I only get mono sound while capturing(Pinnacle drivers, what do you expect?).
Now I have figured out through trial and error to just capture in mono sound and later when encoding TMPGenc(using toolame for audio) instead of encoding the sound as Stereo to select Joint-Stereo or Dual-Channal mode. Note: when you load your file in TMPGenc the audio bitrate will be 192, this is ok, just make sure that when using the bitrate calculator you remember this.
take a quick look at the lower right hand corner of your VirtualDub capture window, you will see your audio setting(44k/16/m), your frame rate(29.97 for NTSC or 25 for PAL), and the data rate(this will vary depending on you settings. Here are what my rates look like...
ok, now you are set to capture with very little frame loss. After you have captured to your little hearts content edit with trusty old VirtualDub. Now, use a bitrate calculator(I prefer the one on this site located here. Get your bitrate, set yourself up to frame serve(from VirtualDub) to TMPGenc, encode using CQ with the both bitrates the same and then burn with your favorite burning program. Hope this helps some people. Let me know what you think. Also, If need be I can advise you on the use of AVI_IO. Thanx for reading my guide!
