    Just a quickie before I patch - does the FM upgrade reset your settings?

    Yea, reducing quality... but improving the "look" for us picky cinema junkies. ;)

    I'll keep it to the other forum, as not to confuse people...

    so the reccommend settings were just to change the bitrate to 42?
  • Angry_CAngry_C
    Transcend class 10 32GB
    Sandisk extreme pro 16 GB 45mb/s

    recommended settings:

    FSH: Freeze on high detailed scenes
    FH: Everything goes fine
    24: Everything goes fine

    I think both cards should be able to shoot 42 Mbit without problems.

    Will the original firmware 24 H/L still be intact after the hack? Can I choose to shoot between 24H/L and the new hack 42 FSH/FH.
  • APXmusicAPXmusic
    @PixCanFly The firmware is only changed if YOU enable the changes!

    You can try to play with video buffer. It defaults at 0x3000000 with bitrate patch active.
    You can set it slightly higher. Ideally it must be at 0x4400000, but camera hangs if I remember correctly.
    Other option is to play with other new settings in testers section.

    Combined 1080p 30 (80%) at 44mb and SH 720p at 48mb
  • arvidtparvidtp
    Using the recommended high bitrate settings I'm getting a message saying motion recording has been cancelled because the camera could not write to the card fast enough - or something to that effect on SH 720p60. To get this error I'm focusing on and shooting the grilles of my speakers and the screens in my windows.

    I can shoot normal scenes with 720p60 ok, but the screens/grilles with lots of detail everywhere kill it. I tried reducing the bitrate for SH down to 24 and I still got the "recording cancelled because card too slow" message.

    I'm using a Patriot LX series 32GB class 10 SDHC card. Maybe this SD card is just crap? What are you guys using?

    1080p30 (the 80% mode) usually works though when shooting the same thing.

    BTW - when you guys say a "freeze" does that mean the camera locks up, or are you referring to the above message from the camera?

    So I can't seem to find these new "recommend Settings" for the new ptools release? A link please?
  • arvidtparvidtp
    they are in Ptool - click the name of each patch and a little window pops up to the side :)

    Did some testing and compared 24p/42mbps to the factory set 24p/16mbps. The average bit rate is doubled, but the footage is not improved at all. I was amazed to see that it is even worse (compared with the factory set 24L setting). Made some 200% crobs and the 42mbps footage is always slightly worse.

    Here some examples:

    @dreamer

    First, why compare it to 16Mbps setting?
    Second, it is impossible to say anything from your crops or resizes of weird size, and do not use jpegs for them next time.
    Thirs, I do not see any Streamparser screnshots.

    Whoever said the meaning of life is 42 was wrong. It is actually 32. Well at least that is the magic number that stops the 1st second of video from messing up. If you enter 32000000 for Video Bit rate FSH/FH and Video bit rate 24H you will get the maximum default bit rate that is possible.

    I suspect it has something to do with the buffer being set to 30 by default. Vitaliy, do the bit rate settings change the buffer settings behind the scenes? I am going to try raising the buffer and bit rate above 30 now and see if that helps.

    It is important to remember that just trying for the highest bit rate possible is not going to get us anywhere. We need everyone to systematically test one variable at a time. Make a change to one setting and test what happens. If it messes things up then see if a different value for that one setting fixes it. Systematic testing like this will get us to the promised land much sooner than everyone saying "I got XXX bit rate to record a partially jumbled picture".

    I see no difference in those pictures at all.
  • Vitaliy_KiselevVitaliy_Kiselev
    First I frame on your screenshots is anyway very compressed, as well as few frames in first GOP.
  • mpgxsvcdmpgxsvcd
    @Vitaliy

    Yes it is compressed. However, it is the highest setting I could use without the affects showing up in playback on the cameras LCD screen. The time for that "Low Bit rate" is very short so it should be acceptable for most people.

    My goal right now is to get stable high bit rate video. I think it is important to get it stable at its limit first and then find out what you can do to get it to push past those limits.
  • Vitaliy_KiselevVitaliy_Kiselev
    @mpgxsvcd

    Better tell me exact top bitrate number that do not result in very low bitrate.
    Using binary search technique.
  • mpgxsvcdmpgxsvcd
    Adjusting Buffer up to 36 still had the artifacts in 24p with a bit rate of 34. It also caused the camera to crash in 720p mode.

    I am sticking with 32000000 as the best bit rate for now. I also found that if you increase the bit rate for the Low settings it will cause the camera to record a very low bit rate video occasionally.

    For now just too simple changes can increase the bit rate significantly and still provide very stable video. 32000000 is the answer for now.

    Yes...Thanks for the reminder

    Do you really want me to stay up all night? It is 2:06 AM here already. What time is it where you are?
  • EOSHDEOSHD
    @mpgxsccd that is nothing I am up at 8.30am! Ignite your passion dude!
  • mpgxsvcdmpgxsvcd
    So here is my best effort at it. These are all stable with no problems playing back or having to record 1080p first. The Low settings are the stock low settings for comparison. I really couldn't tell a difference for the 1080p @ 24 FPS for low vs. high. However, the 1080i and 720p screen shots showed some differences. I will shoot some leaves with it tomorrow. I am tired. I am going to bed.
