    Urgent Help Needed: Best Export Settings for AVCHD footage

    Hey all,

    I'm in need of urgent help ... I'm trying to export a file which was shot in AVCHD ... I want to have HD quick time movie ...  I'm exporting it in H264 ... The duration of pkg is around 7 minutes and the file size was around 7 GB ...

    But when I uploaded the file on youtube, the quality was real bad ... Following is the link of my pkg so that you can have an idea, what exactly I mean by it ... There were visible black lines as well, which was not in the original footage ...

    https://www.youtube.com/watch?v=pcXbZmXKcBU

    Is there something I'm doing wrong? What should be the best settings for exporting the file? Is there a way I can fix it?

    Thanks

    Re: Urgent Help Needed: Best Export Settings for AVCHD footage

    I thought the clip looked fine when you reset YouTube to the 1080 quality setting.  Thats the little gear wheel icon at the bottom of the screen. YouTube defaults to 480 I believe for regular playback.  I do see some jaggy lines in the video, have you tried deinterlacing in the export function?

    Wow, 7GB for 7 minutes. That's about 133Mb/s!  20Mb/s would have been quite sufficient. I agree with Tom, when you look at the piece in 1080HD, you can see interlace artefacts.  

    The deinterlace selection is, confusingly, in the Size... settings

    Re: Urgent Help Needed: Best Export Settings for AVCHD footage

    I can still see the black lines when I'm playing it in HD ...
    I actually didn't get the deinterlacing option when I was trying to import it ... Is there a way you can guide me step by step for the export of HD footage in H264 or any other recommended format?

    I'll be grateful ...

    MACH:

    Hey all,

    I'm trying to export a file which was shot in AVCHD.

    I want to have HD quick time movie.

    Transcode the AVCHD footage to DNxHD. Try a clip at, say, DNxHD 220. Then try transcoding at 145 or whatever's lower bitrate's available to your project. Play back at each clip. If they look the same, you can save disk space by going with the lower bitrate.

    You could also try exporting an MOV with the Avid codecs. Which leads to...

    If you're making the H.264 out of Media Composer, don't.

    Instead:

    1. Export a QuickTime Reference.

    2. Encode the H.264-based MP4 in something like MPEG Streamclip:
