The video I got has a black frame that causes a brief flash when viewing.
Is it possible to delete that black frame without affecting the audio/video
sync? I have Premiere Pro. I'm afraid that it would be out of sync if I
extract the audio, cut the the video to half (so the black screen is
eliminated), and put them back to timeline. Any better ways to solve this?

THANKS for the help,

Why not briefly put a different scene without the audio on top of it. Sort
of like when they do a TV interview, cut/switch to behind the speakers head,
then cut back to the main shot. If you have extra footage that "fits" the
theme, that's what I'd try. Just an idea. Leave your main audio track
untouched. Fade in, jump cut or use whatever fits best.

Since I don't know the subject or content of the video this may not
work. Could you just add one more copy of the last frame before the
black frame as a video insert. If your subject allows this it seems
like it could solve your problem????

Better yet, include a subliminal message like "Reduce the National Debt"

That's what I was gonna say. Either the last frame before the black, or the
first frame after.

I don't know offhand if Premiere has the same versatility as Avid, but
there are likely as many solutions to this problem as editors who post
to these forums.

I'd have to see the clip with sound and adjacent material to determine
my own solution, but can make a few suggestions:

Zap the black frame and substitute the preceding (or following) one. If
the audio is dialog, you could probably even get away with zapping the
frame and letting the audio be one frame out of sync until there is an
audio pause enabling a zapped audio frame to 'catch up' so to speak --
this is not as sloppy and unprofessional as some people might think.
When you realize the amount of looped dialog in many feature movies and
TV shows, flawless sync is not as common as one might expect.

Another standard fix for such problems is to insert a cutaway video clip
if the project enables anything appropriate: eg, if someone on screen
is talking (being interviewed, giving a speech etc.) insert a cutaway to
the interviewer or audience, if possible, or perhaps an image that
relates to whatever the speaker is discussing.

Thank you all for the suggestions. I will try replacing the black screen
with a frame from the previous screen method. Let's see if Premiere Pro can
take that task.

Thanks,

Just out of curiosity -

if you only have one frame in a video and if your video is 30 fps, how
can you see the frame ?

..In the same manner cutting out the one frame and joining the two
segments should not be very noticable in audio. (depending on exactly
what the audio is.)

Wow, now I feel important since you and I had the same idea.
I respect your input on this group considerably Farny....:-)

Also the suggestion to just cut the frame sounds like it would also
work depending on what it does to the audio.

I agree best solution is to cut the video frame and at the next audio pause cut
a frame out there. If there is no music this should work. One frame out of sync
is not that big of deal for a short time with lip sync. In fact in the film days
you could often only get to one half frame accuracy between visual and audio
sync. But yes, you do see one frame. Remember academy leader and the 2 beep.
That 2 is one frame.

To clarify my remark about one frame and 2 beep. I was referring to comment by

You have two situations... one "bad" video/audio frame in the
project, or one video/audio frame missing.

First, the second case. You can cut any one or two video/audio frames
from a project any no-one on earth would be able to find it. Some
people say they can, but even trained musicians cannot detect less
than one fifth of a second missing from a sound, most of us cannot
detect a missing half second.

Now, the second case. Almost anyone can see and hear an extraneous
video/audio frame in a project. Think of a flash going off or a loud
sound "blip." A flash is much less than the length of one frame, yet
almost everyone can see it go off. A "flash" of black is not nearly
as noticeable, especially in a dark sequence, but under the proper
conditions most people will still notice something amiss, even if they
don't know what happened.

So, if the original poster wants to handle the "flash" of light or
dark, or a "blip" of sound, the easiest and least detectable way is to
simply cut the clip on the offending frame, and remove a frame on
either side of the cut. No-one will be able to see or hear the
missing 1/15 second (assuming NTSC).

I cannot imagine anyone telling the original poster to go to all the
trouble of "replacing" the offending frame, or even more stupid,
telling him to take a chance of screwing-up his sound sync.

Hope this helps,

Susan

"even trained musicians cannot detect less than one fifth of a second missing
from a sound"
It depends on what's missing. Take the word "train". Remove the first frame of
that spoken word and you have "rain". Remove the frame that contains the
beginning of a piano note and it will sound terrible. Even removing a frame in
the middle of a sustained violin sound or the like will often cause a "glitch"
sound. A bump in the sound that is noticeable.
