    I like that movie, movie!

    @bkmcwd just posted my codec torture movie (thanks, mate!): http://personal-view.com/talks/discussion/comment/137209#Comment_137209

    that is the movie the respective "codec torture" screenshots from above refer to.

    Here is HQ3GOP V2

    The setting is now adjusted for PAL and NTSC modes: 24H, HBR/25p, FSH/50i, HBR/30p, FSH/60i, SH 720p50, SH 720p60.

    25p/50i is the same as in V1 ... all other modes have been improved.

    I have not yet tested the lower modes (24L, FH, H).

    All 1080-modes (24H, HBR/25p and HBR/30p) and 720p50 survived my codec torture movie even on SanDisk SDHC 30MB/s 16GB cards. 720p60 requires SanDisk SDHC 95MB/s 32GB cards or faster.

    In camera playback works. Spanning not yet tested.

    @towi

    As noted above I've successfully tested HQ3GOP in HBR/25 mode on SanDisk 30MB/s 16GB cards on an extremely stressing codec torture movie.

    I got it, but I need both 24p and 25p to be reliable on my 30mbs cards. I'll check 24L (maybe HQ3GOP.2 one) when I have time to. Thanks for this new patch.

    BTW - when I compare HQ3GOP against @bkmcwd's settings it's absolutely not my intention to devalue bkmcwd's settings in any way. Quite the opposite we have been working closely together over months to improve and stabilze the settings and bkmcwd's settings are by far the best for HBR-mode in 3GOP (IMHO). Also HQ3GOP is based on bkmcwd's brilliant work (actually it's a modified bkmcwd-setting, just with a different matrix). I just wanted to make this clear in order to avoid ambiguities!

    HQ3GOP vs. Duke (Beta 1 !!)

    • First attachment shows a pan over a highly detailed scene (foliage/outdoor daylight) in HBR/25p mode. While HQ3GOP and Duke Beta 1 both produce the same I-Frame sizes HQ3GOP again produces larger B-Frames. JM-SP-Decoder data looks pretty much the same.

    • Second attachment shows a lowkey scene (narrow DOF, little detail to resolve) in HBR/25p mode. Duke Beta 1 shows larger I-Frames, HQ3GOP shows larger B-Frames. JM-SP-Decoder data of HQ3GOP looks a bit more balanced (constant QP on I- and B-Frames).

    • Third attachment shows Duke Beta 1 vs. the soon to be released HQ3GOP.2 in 24H mode (in HQ3GOP.2 24H will be vastly improved ... it's pretty much finished and I think I can post it later today). Same scene as attachment 1 (pan over foliage). Same I-Frame sizes, HQ3GOP again shows larger B-Frames and lower quantization.

    Further plans: in HQ3GOP.3 720p50 will be improved (most likely also 3GOP instead of 6GOP). As soon as 24p and PAL modes are finished I am going to adjust NTSC modes.

    Nick,

    many thanks! In fact I am very pleased with this setting especially in 25p mode. You know very well this setting would never exist without the extremely valuable exchange with you... all the things I've learnt from you (and @bkmcwd). I thank you!

    Now let's bring Spizz T6 to life ...

  • driftwooddriftwood

    @towi Its a very good setting Thomas, and tantamount to the hard work you have done in research over the years. Excellent stuff.

    Great work, towi

    @rikyxxx

    Thanks!

    Unfortunately I'm not going to patch my GH2 with HQ3GOP since I have only a couple of "poor" SanDisk 30MB/s cards

    As noted above I've successfully tested HQ3GOP in HBR/25 mode on SanDisk 30MB/s 16GB cards on an extremely stressing codec torture movie. I have not yet tested it on SanDisk 30MB/s 8GB cards (since I don't use them anymore).

    @spreeni

    Is the used driftwood matrix the one used in moon t7

    no. It's not present in any of driftwoods settings. He has given it to me 2 years ago or so ...

  • spreenispreeni

    @towie Is the used driftwood matrix the one used in moon t7, for softer pictures with over-sharp Panasonic lenses?

  • rikyxxxrikyxxx

    Very interesting. Unfortunately I'm not going to patch my GH2 with HQ3GOP since I have only a couple of "poor" SanDisk 30MB/s cards but, as a user of your Sanity 3.1 HQ settings, I'm glad you're keeping on experimenting. PAL people owe you a lot.

    HQ3GOP versus Valkyrie 444 TZ4.2 in HBR/25p mode...

    First attachment shows a codec torture movie (first frames show static high detail followed by motion). Second attachment shows a low key scene with narrow depth of field (little detail to resolve).

    While both settings produce comparable I-Frame sizes HQ3GOP produces significantly larger B-Frames (under all shooting conditions).
