High quality, low bitrate H.264
Hi all, I need to convert some 1080i 29.97fps AVCHD footage to good quality, lowest bitrate possible, either 720P or maybe 864x486 for downloadable product sales. I've heard that MeGUI coupled with QTGMC will provide good results. I'm using an OC'd i7-2600 with 8GB of memory so I'm interested in using the MT version of avisynth. Any suggestions for good script/settings? Encode time is not a concern, but high quality and low bitrate is. All footage is filmed in a studio environment with proper lighting, camera films at 16-255 levels. I have high quality video to start with so I'm hoping to get well under 1Mb/s.

I don't think i'll be able to post a sample of the video. Relatively low motion, similar to a talking head if that helps. Isn't Lanczos resizing much better than bicubic? x264 has so many settings it's hard to know what to set, or should I just choose the "slowest" preset? And what about QTGMC deinterlacing, that's supposedly the best free tool available.

Lanczos/Spline etc are sharp, this causes slight haloing, and sharp/haloing are hard to compress as far as i know. Bicubic, Billinear etc are "blurry", this should be easier to compress. in short: Sharp -> higher bitrates to keep quality Less-Sharp/More Blurry -> lower bitrates to keep quality Quote:
This MAY be wrong, but i am pretty sure this rule is always followed except rare cases, at least x264(h264) which is the codec of discussion. Last edited by zerowalker; 14th May 2014 at 17:36. |

I briefly looked at that program, but it appears to only be for making backups of DVDs. Did I miss something? I'm coming from the bubblevision.com/underwater-video/Vegas-YouTube-Vimeo.htm tutorial which uses the Lanczos method so I was under the impression it was the best, along with QTGMC for deinterlacing...

Using slow qtmc does not make sense if you plan to downscale image 2-4 times. Simple fast yadif is enough.

@MikeC
You say, "I briefly looked at that program, but it appears to only be for making backups of DVDs. Did I miss something?" Yes, you've missed reading about the MANY available conversion capabilities of BD Rebuilder in addition to conversion to DVD... |

I think it would be simpler If you just used Ripbot264 for this task.
