Re: What does RF: in constant quality stand for?

@jamiemlaw, I tried your proposed settings at RF 10, 14.5 and 19. There were still noticeable defects at RF 14.5 and 19. I didn't see any differences compared to my previous settings. Your point would be a lot clearer if you posted a few matched-frame screenshots at RF 10 versus 14.5 and 19, so we ...

Re: anamophic for 4:3 material?

DVDs are anamorphic sources, so to best preserve their quality while not wasting extra bits by upscaling, you use anamorphic encoding. Why did you change from loose to strict may I ask? Strict theoretically produces slightly better image quality, because it avoids resizing the image prior to encodin...

then rename output extension to .mp4, taking out the .mkv default extension. Don't do this, you're mislabelling an MKV file. If the player isn't capable of reading MKV files, it simply won't play the file no matter what you do. I would try the programs: AVImux GUI and/or YAMB first. YAMB is the rig...

Re: Handbrake quality is better than Premiere CS5 output!!!

The stripped-down version of Mainconcept in Premiere simply can't match x264's quality or compression efficiency. Mainconcept's advanced encoders can, but they're not commonly available in consumer video applications. x264 is the leading commonly available encoder, and can easily match even speciali...

Re: Handbrake Vs little or no loss of quality?

To add to what TedJ said, the tradeoff between Strict and Loose is as follows: Strict: prevents rescaling inaccuracies and artifacts (which always occur with non-multiple scalings). Resulting frame is invisibly padded with edge pixels to mod16 by x264. This padding, which consists of repeated edge p...

Re: Blu-ray -> New AppleTV: Ripping HW/SW advice needed

On the other hand, I've seen some pretty crappy screenshots from an RF 22 720p encode (by my standards anyway). It does depend on how much fine detail and grain you intend to keep, and on the compressibility of the source itself.

You haven't even specified exactly what devices you're trying to play the encodes on, and the connections the encodes are being streamed over. You'll need to provide information on those.

Re: Encoder settings for optimal quality?

Okay, so say an RF15encode chucked out a 2.5GB file. If I define a target size of 2.5GB instead would the quality be better than the RF15 encode because of the multi-passes or whatever? In a nutshell, no. The 2nd pass of a 2-pass encode is essentially the same thing as a CQ/CRF encode. RF15 is over...

Re: Settings for LECTURES and still pictures?

A psy-rd of 2.0 and aq-strength of 1.2 are going to increase the bitrate requirements rather than decrease them (but provide better texture and grain retention). For the OP's purposes, psy-rd should probably be somewhat lowered from the default of 1.0, and aq-strength possibly lowered as well.

Re: Quality optimization concerning Cropping and De-Anamorph

No. If a source is anamorphic, for best quality you completely avoid resizing it during the encode stage. It's useless to resize to square pixels since it gets resized anyway during fullscreen playback. So optimally you would limit the resizing to one stage only: the decoding. Also, mod16 resolution...

Re: Do I use Strict or Loose Anamorphic?

Well in any case, I'm not convinced now. On the perfectly-shot studio programme, viewing both the original and the handbrake rip using VLC, there's no colour difference I can see. I now suspect it might be a difference in *Quicktime's* decoder/renderer; a playback issue with a given player. Yeah......
