![]() Redwudz, I also leave Detelecine and Decomb as "default". I will use a lower RF because this is a quality film and it makes a difference. This 1993 film has a ton of grain but that is part of the 1940s genre that it is projecting. However, for "Body of Evidence" I don't use a filter. I will use a higher RF because it is more of a throw away film. So if I want to do something stronger, I am using a custom setting of 1:1:7:7.Īs an example, I might use 1:1:7:7 on a film like "Billy Jack" (1971) - it is a film where the DVD shows its age. I fear the "medium" and "strong" options may be a little heavy handed. If i use the canned options, I tend to the "weak" option it does seem to help a bit with older film. The first two are more blunt or less forgiving. The last two looks at multiple frames together. Hello, you are right that Handbrake options have different settings. Right now I do one at a time and using the "very slow" setting means a long time between encodes. I will look at more if I start encoding in bulk. I might should have looked at that prior to delving into all the diffferent settings. I wonder if this is a difference in versions. When I left click the CQ bar in Handbrake, it only increments by whole units. Redwudz, I must be doing something wrong. Maybe give Handbrake's denoising a spin with it. There's also an unfiltered version with the samples. As an example of what QTGMC can do, there's a comparison of a few of the better Avisynth noise filters here (more in the first post) using a fair example of crappy quality video for the source. ![]() For re-encoding progressive video (applying inverse telecine first if necessary) I often use QTGMC in progressive mode as a noise filter, (even though it's officially a de-interlacer). If you're serious about experimenting with denoising then using an Avisynth based GUI such as MeGUI might be an idea, although there'll be more of a learning curve and it can be time consuming. I don't use Handbrake so I can't help much there, but there's lots of different noise filters for Avisynth. I'm pretty sure Handbrake uses Yadif for de-interlacing.Īny denoising is a compromise between removing noise and blurring the picture (which can produce a "cartoonish" effect). Handbrake can do it by selecting "bob" as the de-interlacer and choosing the appropriate "constant frame rate" for the output.įor some full frame rate vs half frame rate de-interlacing comparisons, have a look at post #8 here. For NTSC that'd be de-interlacing to 59.94fps rather than 29.97. The log file will probably tell you exactly what's happening.Īs you mentioned it, if you know a video is interlaced (no telecine), de-interlacing to "full frame rate" usually looks much better than "half frame rate". The link is for the AVIsynth version, but I assume Handbrake's different filter options use different HQDN3D settings to achieve different denoising strengths. What am I missing?Īccording to Handbrake's help file it uses the HQDN3D noise filter. VS is supposed to increase the quality and decrease the size. Maybe provide some examples of old movies they have cleaned up.īTW - I used CQ 19 for a lot of these old moves and the encoding of "Very Slow" (VS). Not great though.Īnyone want to provide some guidance on when/how to use the Denoise filter. The original it is pretty grainy and noise increases size. They look a bit plastic but overall not bad. I used "Billy Jack" (1971) for an experiment setting the Denoise to "medium". I experiment with Denoise set to "weak" with good results. However, I have some DVDs of old movies that I think may benefit from using a Denoise filter. I have been using the Handbrake filters as Detelicine and Decomb set to "default" and deinterlace and denoise set to "off". I use MakeMKV for the rip and Handbrake for the encode. Everything is hooked up to a Yamaha V671 receiver and output to a 42 inch vizeo LCD. Over the holidays, I have continued ripping my DVD and BluRay collection and then compressing them. ![]()
