Answers.Text: @Prometheus There are a lot of factors that go into choosing the right bit rate for a workflow. What codec? What are you going to do with the encoded material?

Body: <p>I have this situation:</p>
  
  <p>I have two VCRs, one is a simple LG VHS VCR. It is one of the latest VCRs, with 4 heads and is standard (composite, not S-Video output). The quality is really poor.</p>
  
  <p>The other VCR is Mitshubishi MD-3000 SVHS medical VCR. It was bought new. The quality is fine and sharp when playing SVHS tapes, but during VHS playback. I lost a lot of frames. I have only old vhs tapes and some of them <em>really</em> old. I get strange blue and red pictures.</p>
  
  <p>The question is, if I transfer from VHS playing from the LG to SVHS  recording on the Misthubishi, will i get a good quality recording and can I transfer to my video capture card? Or is this only a waste of time?</p>

  I have this situation:
  
  I have two VCRs, one is a simple LG VHS VCR. It is one of the latest VCRs, with 4 heads and is standard (composite, not S-Video output). The quality is really poor.
  
  The other VCR is Mitshubishi MD-3000 SVHS medical VCR. It was bought new. The quality is fine and sharp when playing SVHS tapes, but during VHS playback. I lost a lot of frames. I have only old vhs tapes and some of them *really* old. I get strange blue and red pictures.
  
  The question is, if I transfer from VHS playing from the LG to SVHS recording on the Misthubishi, will i get a good quality recording and can I transfer to my video capture card? Or is this only a waste of time?

  You can't improve the quality of a bad recording. Especially if it is because the tape stock is flaking off oxide or is stretched, both of which are common problems with older tape stock. No matter what tape format you transfer it to, it will likely just get worse.
  
  You might get about the same quality by digitizing with your capture card. However, you will likely need to use a fairly high bit rate, because analog artifacts have a tendency to cause low bit rate compression to induce even worse digital artifacts. If you use a low bit rate, expect the quality to worsen when you digitize it.
