    Hello,

    Can we expect a higher bitrate than 5 Mbits/s for HDMI in, or is it a hardware limitation?
    I find that full HD videos are too compressed, I have to reduce the capture size to HD.
    10 Mbits/s would be perfect.
    Regards

    Thank you for your feedback. We are trying our best to do it.

    There is a limitation of encoder involed software and hardware. By now the bitrate is the best for x9. If we increase more, record will lost frame.
    This will be a R&D direction of us, to record higher definition videos.

    720p @15mbs would be ok
    I just notice that the codec is h265
    Can someone post some proper video recorded so I can have a looksee please?

    I think the bitrate is going to be ok for me
    It all depends on the source.
    Heavily compressed sources will suffer when squeezed yet again by the x9 h.265 but in a few days when mine arrives we'll see how it handles pristine video input

    Got mine this morning
    I compared video off the memory card straight from a sony ax100 to the same scene recorded at the same time to the x9 and the video is remarkably similar
    File size of the video recorded by the x9 is 90% smaller than the xavc-s recorded by the ax100. The recorded video is certainly good enough for most purposes and using firmware 1.0.2.8 am filming a long speech to see if the a/v sync holds.

    recorded for 1 hour and 49 minutes and the audio video stayed in sync.
    Why did it stop recording at 4gb?

    File system limits。We will change to auto save next file when at 4GB。

    If you use NTFS and record with ts, then you won't have size limitation problem. But, NTFS with mp4 recording still have file size limitation though.

    What video converting software are people using/experimenting with to convert the .TS and what format/settings do they find to get a good quality and clean .mp4, .mkv or other format.
    Thanks

    I currently do not have TS files from the Zidoo box but for DVB-S/C recordings I'm using the TS Doctor. It will clean the streams, adjust the PTS data (in case they are wrong), is able to cut H.264 files and finally is able to convert to MKV.

    There is a free trial version at
    http://www.cypheros.de/tsdoctor_e.html

    It will not do a re-encoding so no quality change. For something like that you may take a look to Staxrip or Handbrake. Both tools are available for free download and usage, but expect CPU or at least GPU power ;)

    Thanks @Jens I have Handbrake no good with v28, and thanks for the other to look at.

    For Video Editing "TMPGENC Video Mastering Works 6" Costs money but nothing better

    My first interest to to convert the .ts to .mp4 or .mkv smaller size, but quality. tried a few basic converters the finish not as good, new to this area of converting
    Thanks

    Everybody is new to this H.265 codec and everybody will be using it everywhere pretty soon when services catch up such as youtube and mainstream editors.
    The beauty of H.265 is that the file size is so small and it is designed for online streaming with a low bitrate and nice quality visuals.
    It probably won't stand up to things like color grading and other corrective measures used in video production but as a delivery format for on line it is a godsend. Now 4k can be streamed with no effort.
    Even the file extension tells us what it's about .ts means "transport stream"
    I found that Freemake video converter can handle the files and convert them to whatever and as the name implies it is free but the trick is to produce it and use it without any intermediate processing such as conversion etc.
    I'm no expert in the field but for my purpose which is video recording and live streaming, the x9 is a wonderful tool which performs brilliantly for next to nothing cost wise

    Great will have a look see, I also guess the finished product is only going to be as good as the original you are converting.
    Thanks.
