There are others on this board much better qualified than I to advise on the process of getting the video off the DVD in the first place so I will not go into that here. If you have to encode interlaced video then the interlaced mode optimization switch will help, but interlaced video is always harder to encode than progressive scan material, so avoid it if at all possible. In general I would suggest that you de-interlace you video before you encode it rather than encoding the raw interlaced video using “interlaced mode”. If you are going to play back off something like a CD or hard drive then VBR or “Local File Playback” is your best option. These really only come into their own at much lower rates.ĬBR (or “Stream from Server”) is designed for case where you want to stream your video over a fixed bandwidth link and it enforces strict buffering constraints.

Pre-processing / noise reduction techniques can help improve the visual quality if the source is noisy but will always tend to hurt metrics numbers.įor coding a movie at around 750K I would avoid temporal or spatial re-sampling. I would keep the pre-processing set to 0 unless you have a very noisy source. Find a value that suits your preferences and stick with it. I would not recommend that you try and tune this on a clip by clip basis, particularly if you are going to encode at best quality (note that good quality speed 0 is almost as good on most clips and about twice as fast), because you will waste a lot of time.
The default value of 0 will usually give the best metrics response but some people are willing to accept some increase in the level of some artifacts in return for more sharpness. Things like sharpness are a bit of a matter of personal taste. It is always possible to get some improvement in metrics or psycho visual characteristics by fiddling with the various VBR settings, sharpness settings and preprocessing level, especially on short clips, but we have set what we believe to be reasonable defaults that should give you reliably good results.

If you want a 2 hour DVD to fit on a single CD then about 750Kbits/sec is a good starting point and should give you something eminently watch-able, as most real movies are overall easier to encode than movie trailers, which tend to have 50% of the action crammed into 2-3 minutes plus tons of scene cuts, fades etc. Regarding you first question, I am sorry if this sounds obvious but the rate you choose depends on how big you want the final file to be. solved problem on non intel machines that shut off mmx optimizations of decoder added slider which controls how much filtering to do fixed problem in which video offset by 1 pixel when using noise reduction better quality video across wide range of video fixed bug that produced artifacts in faster speeds ( 2,4,5) when image For example, the HPII trailer previously used by Saggitaire was at the low end of the spectrum but we still saw a small improvement in psnr and an improvement in SSIM ranging from 0.3 at best quality through to about 0.5 at good quality speeds 4&5. We have seen some clips where the improvement in overall PSNR was as high as 0.75db and isolated sections where it was much higher.Įven on low motion clips, however, the changes seem to have helped. Though this is not very common, there are exceptions and for these the improvement can be dramatic. Obviously the biggest gains are for clips that contain a lot of very high motion. As a result, for most of the clips we have tested the new release is actually a little faster. We were keen to address this problem without hurting average encode speed and to this end we have made significant changes to the motion search strategy. This release removes a previous limitation that prevented the encoder from detecting and tracking motion of greater than 31 ¾ pels. These changes affect both the first and second pass.
