  • Rendering Sony AVCHD (.mt2s format) higher than 15Mbps

    Posted by Masaaki Yoshigi on October 23, 2012 at 3:58 pm

    Hi All,

    I posted a similar question but I’ll bump up with additional information.

    I’m using Vegas Pro 11, and tried to render AVCHD file captured by NEX VG20 in FH (1920×1080/60i 17Mbps) and FX (1920×1080/60i 24Mbps) formats. Rendering template was Sony AVCHD, so basically rendering in the same format.

    After trying several rendering bitrate, 10Mbps, 15Mbps, and 22Mbps, I found rendering higher than 15Mbps makes the video completely unusable. The first few minutes work okay, but then video frames stutter and sometimes goes faster, and then stop as a still image when a few minutes fastforward. Same thing happened with BOTH FH and FX format as source files.

    So this begs a question, are you guys able to render in Sony AVCHD format, higher than >15Mbps bitrate? I might try re-installing Vegas Pro in another PC, cause I suspect something like Movie Studio files/codecs are causing this.

    Anyway, thanks for reading, and appreciate your comments!

    Please post the specs for the computer you are using to play back the 15Mbps file.

    Jeff, thanks for replying.
    Yes, Intel i7 950 3.06GHz processor, on Gigabyte X58 motherboard (GA-X58-UD3R), 12GB RAM, Windows 7 pro 64bit, 256GB SSD for OS/application, and Seagate 1TB 7200RPM drive for data/videos. Vegas Pro 11 is 64 bit version (haven’t tried 32bit version). GPU is XFX Double D HD-687A, which is Radeon HD6870 chip board (with the latest driver). I usually use Eyefinity for three HD monitors.

    I can suggest a laptop would choke at 15 Mbps, but not this machine.
    Have you ever used a codec pack? (bad idea)

    “Codec pack” means something like installation of free trial version, like Cyberlink WinDVD, or something similar, that may install various codecs?

    If that’s something I have to diagnose one by one, then I have another machine, I can wipe out the HD anytime, and clean install everything (to make OS, Vegast only machine).

    Thanks for suggestions!

    Interesting thing is, I can play the original FX file (Sony AVCHD .mt2s file, 24Mbps bitrate) without any issues. It becomes garbled only after rendering, which is the same format but different bitrate. I guess codec that is used to render the Sony AVCHD format has been screwed up by something else.

    I meant .m2ts file format….not .mt2s

    So easy to screw up one little character.

    Hi sir…..if you install the k-lite codec pack,pls remove it and pls re-install the sv 11,because this codec can drop the quality.

    Thank you for chiming in.
    I tried Sony AVCHD rendering in a machine with Win 7 64bit fresh install (so absolutely no codec packs or anything, just OS and Vegas), but the same thing happened.

    After 1 minute and 45sec, almost consistently the video drops frames.

    I guess something is wrong the the encoding plug in for Sony AVCHD format?

    Can anybody try the same rendering (.m2ts) and see this is only with me or not?

    Thank you all.

    Hi sir……..pls post the stream file properties

    Hi,

    The stream file (the media source file, am I understanding correct?) is captured by Sony NEX VG20 in FH mode, and the ‘media’ tab of the ‘property’ from the Vegas Pro shows the followings:

    Format: AVC
    Attributes: 1920x1080x12
    Frame rate: 29.970 (NTSC) – greyed out
    Field order: Upper field first
    Pixel aspect ration: 1.0000 (Square)
    Alpha channel: None
    Rotation: 0 degree (original)
    Stereoscopic 3D mode: Off

    Time code shows “Use timecode in file” is selected.

    Are there anything I can change in this ‘property’ to solve this issue?
