Distorted image while viewing exported clip in VLC or QuickTime (FCP7.0)
on Jul 1, 2016 at 1:48:31 pm

Hello,

I am digitizing mini-DV tapes for a client using FCP7.0 and a professional Sony DEC HVR-M15AU
The footage is 720x480 60i

The first image is the image as seen in FCP 7.0 (after digitizing).
The second image (at the same timecode as the first image) is how I see it in VLC or QuickTime.

Exported the clip using DV/DVCPRO codec (NOT AppleProRes).

I was wondering if anyone knew why there is such serious distorting in the image? It is more visible when there is a lot of movement.
Any help will be highly appreciated.

Thanks a lot!

that's not distortion, that's interlacing.
your video was shot interlaced, 2 separate fields for each frame (look it up)

FCP just shows you one field only, so it looks fine there
computer displays can't do that, they show both fields at once,
giving you that doubled up look,
and yes, the more movement, the more you'll see it.

if a computer screen is where the videos are to be seen, you need to de-interlace them in FCP before you export.
FCP has it's own de-interlace filter, it;s OK.
but Natress G Smart De-Interlace is the best quality de-interlace you can get in FCP.

you can also use the free JES De-interlacer outside of FCP on your exports

if you are making a DVD or going back to tape, then don't worry, interlaced is acceptable.



cheers,
nick

(and you should upgrade to FCP 7.03)

i'll add that BLENDING the fields can help in some instances, like your wide shots with the stair stepping in your other thread.
both fields get blended together, helping resolution.
BUT
blending won't do anything at all for what you ask about here,
in fact what your seeing IS a sort of blending.
really bad on movement, can be useful on wide shots.
