    "correct" for what purpose ? what is your goal ?

  3. I ripped all my bluray disk with make mkv and I'm almost out of space on my hard drive (2tb Popcorn Hour) 32 inch tv

    Sorry, I still don't understand . Are you asking a question ?

    Does the exported MKV play ok on the Popcorn Hour?

    Can you clarify your question ? What are you looking for ?

    I'm no Handbrake expert, but can you use Constant in the Frame Rate Model setting? Variable frame rate is not a good idea if you have a way to avoid it.

    Is there a reason why you are using 1280x688 instead of 1280x720?

    The OP wants to encode BluRay rips down to a smaller size so his Popcorn Hour box can play them and he unsure if his settings are right.

  6. Yeah use constant for video frame rate, also use 160 or 192kbps constant for audio bitrate. Constant will get you better quality and faster encode times, the file size difference is negligible.

    If you are running out of space you can lower the video bitrate(3000kbps) or buy another external HDD.

  7. At a guess you're using HandBrake's High Profile preset which is the best quality preset without fiddling with x264 settings manually.
    Personally I'd not use 2 pass encoding. The x264 encoder encodes the same way for 2 pass and single pass encoding, the only difference being for one you know what the file size will be but not the quality, while for the other you know what the quality will be but not the file size. I use a CRF value I'm happy with and let the file size be whatever it needs to be. CRF 18 should give you fairly "transparent" quality without the file sizes getting too out of control.

    Vidcoder is an alternative HandBrake GUI you might like to try. The current version of HandBrake doesn't give you access to the built in x264 speed presets, whereas Vidcoder does. The default speed preset is medium and uses pretty much the same settings as your encode. There's nothing wrong with the quality it gives you but slower speed presets can potentially increase the quality a little and/or reduce the file size a bit. However.... they're obviously slower. They don't do anything special as such, they simply adjust some of x264's advanced options according to the speed preset you choose. I've never used a faster speed preset than the default of medium, but I have used the slow, and veryslow presets. To give you an idea, here's the settings the encoder used for an encode using the x264 slow preset.

    cabac=1 / ref=5 / deblock=1:0:0 / analyse=0x3:0x113 / me=umh / subme=8 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=1 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=6 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=50 / rc=crf / mbtree=1 / crf=18.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / ip_ratio=1.40 / aq=1:1.00

    The veryslow preset:

    cabac=1 / ref=8 / deblock=1:0:0 / analyse=0x3:0x133 / me=umh / subme=9 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=3 / lookahead_threads=1 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=60 / rc=crf / mbtree=1 / crf=18.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / ip_ratio=1.40 / aq=1:1.00

    x264 also has tunings such as film and grain. The above used no "tuning". The film tuning uses deblock=1:-1:-1 and psy_rd=1.00:0.15 (I think that's all it changes).
    The number of reference frames can also be adjusted by the x264 encoder according to the chosen x264 Profile and Level so they don't exceed the maximum for that level (coming to Handbrake with the next version, I believe). I use High Profile, Level 4.1
    The above were also PAL encodes, hence the keyint settings being 250 & 25 instead of 240 & 24.
