    my first imported footage: shimmering, barber-polish vertical lines everywhere. Help please.

    Hi there, rather depressing so far. I've shot some test clips with my EX1, and playing them back in the camera, they look great. But when I import them (even 1:1) into Avid, they look horrible. Especially in shots with quite a bit of light, vertical (not horizontal) lines in the shot (along doorways, corners, picture-frames, etc., especially along lines of contrast, eg. where the edge of black picture-frame runs along white print inside) have a barber-pole type effect with zig-zaggy shimmering lines... not during a pan (in the shot I'm looking at now), but as soon as the pan stops. Can anyone tell me if I've got something improperly set in my settings... or what? I'm shooting 1080/30P, HQ (35Mbps); I've tried importing as DV25 411 and 1:1... both have the problem I described above. Thanks, Malcolm

    Re: my first imported footage: shimmering, barber-polish vertical lines everywhere. Help please.

    Aha... o.k., I haven't tried it yet (I will in a moment), but I immediately realized what you're saying, which explains why I saw a window last night saying "This sequence contains the following unsupported feature: Progressive clips within an interlaced project".  That should have been a clue, I have to admit.  Anyway, I've just created a new project in (there was lots to choose from, even in Progressive) 1080p/23.976.

    I hope that's the right one. 

    I'll try it now and report back,

    Thanks so much for the gentle reminder.

    Re: my first imported footage: shimmering, barber-polish vertical lines everywhere. Help please.

    More choices (I'll be happy when everything is properly selected, and I can then leave it alone).

    DNxHD 36, DNxHD 115, DNxHD 175, DNxHD 175X, 1:1 MXF and 1:1p 10b

    any suggestions?  

    I chose what seemed to be the default one (it was highlighted), DNxHD 115, then opened the project, and tried to import the same test clips, and got this message:

    "The edit rate of the import file (29.970000) does not match the edit rate of the project (23.97600)"

     

    Shall I just hit O.K.?, or should I change some setting so everything is harmonized?

    Thanks again, Malcolm

    Re: my first imported footage: shimmering, barber-polish vertical lines everywhere. Help please.

    Malcolm,

    1080/30p is a non-native frame rate for Avid. According to 24p.com, for 1080i/30p, you should set up your project as 1080i/59.94 and the "frames are recorded progressive to an interlaced stream."

    If I were you, however, before shooting I would match your camera to an Avid native frame rate: one that's listed in the options you'd see when you set up a project. Then set up a project accordingly.

    Good luck.

    Re: my first imported footage: shimmering, barber-polish vertical lines everywhere. Help please.

    Hi Brian,

    That's good advice... I'd chosen 1080p/30 on the advice of a training video for the EX... I now realize the guy who put it together was editing with FCP.  

    Here are the possibilities for each half of the Sony/Avid equation:  

    EX-1 list:  1080/60i, 1080/30p, 1080/24p, 720/60p, 720/30p, 720/24p

    Avid list:  23.976p NTSC, 24p NTSC, 30i NTSC, 720p/23.976, 720p/50, 720p/59.94, 1080p/23.976, 1080p/24, 1080p/25, 1080i/50, 1080i/59.94

    By a process of elimination, 1080/24p seems to be the only HQ format Sony and Avid have in common...

    should I go with that?

    thanks, Malcolm

    Re: my first imported footage: shimmering, barber-polish vertical lines everywhere. Help please.

    My process of elimination seems to have eliminated the possibility of editing.

    My camera has been set to HQ 1080/24p.

    Avid project setting:  1080p/24

    But when I try to import a clip into Avid I get the message:  

    'The edit rate of the import file (23,9760000) does not match the edit rate of the project (24,000000).

    Any suggestions would be wonderful.

    Try a 1080/23.97 project.

    And that seems to have solved things!

    Thanks so much,

    Sadly, 24p is not always 24p, depending on the manufacturer.  Some label 24p as a shortcut for 23.976. 

    Avid is particular about this, and the two don't match.  So if one fails you, always try the other.

    Hi Kevin,

    I'm not surprised to hear this - - after all, if it's not confusing enough with dozens of different and mostly incompatible codecs and resolutions and whatnot, why not add to the fun by having codecs with the SAME NAME incompatible?!!

    It does seem to be the case, though, that recording 1080/24p with my Sony camera does in fact seem to work with the Avid project at 1080/23.97... so I shouldn't be complaining too loudly or we all know what will happen.

    Cheers, Malcolm

    Hi Malcolm,

    Out of curiosity, how are you physically importing the footage from the ex1 into your mac?

    Has sony updated the clip browser to work with mac?  Are you processing your clips to mxf files in a PC or in FC?  I am reading your progress in determining the proper format matches, but just what is your workflow?

    Have I missed a major posting here?

    Re: my first imported footage: shimmering, barber-polish vertical lines everywhere. Help please.

    Hi...

    Clip Browser v. 2 should be out in June... the Mac version of this will finally be able to export the EX clips to MXF.  In June Avid will be releasing Media Composer v.3, which may allow for native import of EX1 files.  

    Until then, I'm having to take the MXF step using the PC version of the current Clip Browser (I'm on a MacBook Pro, but I've got Windows XP, when I want it, vis VMWare; it's actually not too bad).

    For the whole (still convoluted) question of workflow, which I for one am still tinkering with, visit the DVi forum dedicated to the EX1:

    http://www.dvinfo.net/conf/forumdisplay.php?s=b37197f03cb9460269b889a02146af36&f=150

    You can start with the thread: first time importing EX clips: need advice

    And if you're an EX1 shooter who edits on a Mac with Avid Media Composer, then let's stay in touch - - most of the EX1 shooters on the forum referred to above edit with FCP or Sony Vega, so their workflows are different.  Shall I start a new thread on this forum on the subject of workflow (EX1, Mac, Avid Media Composer)?

    Cheers, Malcolm
