Actually, my mistake. I had gotten my footage mixed up and it looks like the footage with the horizontal bars was shot at 29.97fps. Back to being a bit confused, ha ha. Your info has definitely been helpful though and I think I’ll shoot everything at 30fps going forward.

[Ben Mears]

Joe, I think you might’ve just hit the nail on the head!

I’m fairly certain the room I was shooting in had fluorescent lighting and the footage was shot at 23.976fps. That frame rate was a mistake because somebody else had used the camera before me, and left it set to 23.9, and I failed to change it. Definitely won’t be doing that again.

I’ve recently been shooting at 29.976fps and haven’t noticed any problem, but I don’t know if I was under fluorescent lights or not. Do you think that frame rate would give the rolling bars as well?

To be safe I think I’ll just start shooting everything at 30fps, ha ha. Thanks a lot for this info, you’ve been immensely helpful!

[Ben Mears]

Awesome, thanks a lot Joe! You’ve been extremely helpful.

It kind of seems like the room is to blame in this case, and for future shoots I’m now always going to shoot some test video and look at it before shooting the real footage, ha ha.

thanks again,

-Ben

Thanks for the reply Joe! At this point it seems like its going to be really hard to remove the lines, but I did find that if I scale the video up and show less of the background, it is less noticeable. Not ideal but I think it’ll be ok. (Tracking and adjusting in After Effects is a good idea, but I don’t think its worth the time and effort that would take, ha ha)

Thanks for the info about what could be causing the problem. When I was framing the shot I did not see the hum/moving bars and I only noticed them after I looked at the recording. How can I avoid this problem in the future?

-I use an AC adapter as a power source for the camera but this has never been an issue before. What kind of power source were you referring to? I was renting an office room for this shoot and I don’t think there were any power sources in it.

-What exactly do you mean by crossing the line sending a video signal to the recorder? I want to be sure I understand this so I can be aware of it for future shoots.

I’ve been shooting video for a long time and have never really experienced this problem before, so its a bit confusing to me.

Thanks a lot for your help! Hopefully you can answer these last couple questions so I don’t run into this issue again.

Cool, thanks a lot Andrew! That workaround seems to have worked pretty well and I can see the waveform graphic after I render and replace the audio clip. Kind of lame that I have to do this for every audio clip but it will definitely make the editing faster and easier so its worth it. Thanks again!

[Ben Mears]

Ok, I’ve exported video and audio together after “rendering and replacing” the problem audio and it seems to have worked fine.

[Ben Mears]

Well, I think I may have found a solution. Here’s what I did:

-First convert all the audio to uncompressed WAV format

-Within Premiere; select an audio clip on the timeline, right click, and select “Edit in Adobe Soundbooth > Render and Replace”. You’ll probably need to do this for every audio clip that is giving you problems.

I think you would need to have Adobe Soundbooth installed for this fix to work since it actually does open the program when you pick the Render and Replace option. However, it replaces the audio clip in the Premiere timeline for you and you don’t really need to do anything beyond this command.

After Rendering and Rreplacing my current audio I exported a WAV and the audio was all there and there were no cutoffs or dropouts. Since I had already encoded alot of the videos I just re-exported all my audio tracks and added them to the videos in Quicktime Pro.

I’m assuming (and really hoping) that this fix will work when I export the video and audio together. I’ll post another update to this thread when I try that out and let you know what happens.

[Ben Mears]

Thanks for your suggestion Jon. Unfortunately it hasn’t seemed to solve the problem.

I did have one intro sound effect clip that was an MP3 and changing it to an uncompressed WAV seemed to fix the problem of that specific sound effect not encoding properly. However, the bulk of my source audio is already uncompressed WAV and that is still giving me problems. I’ve tried re-encoding the audio as well as re-exporting it from the source Quicktime .mov but I still get the dropouts. On my last attempt at re-importing the source audio Premiere actually crashed on me.

I’m pretty sure I don’t have any sound filters turned on since all I’ve done to the audio is cut it up and adjust the audio gain. Audio gain is not considered a sound filter, is it?

Any other ideas or suggestions? thanks again

[Ben Mears]

Thanks for your reply Jeff! I guess I just needed somebody to point out the obvious for me, ha ha.

It looks like Premiere is indeed importing all the clips and stringing them together for me.

I didn’t realize this though because, by default, it names the new clip the same name as the first frame so when I looked at it I thought it was just the first still image. I was also expecting to see the clip with a cut for each frame so seeing it as a solid clip also made me think it was just one image with a longer duration, (I think this might be due to how it looked in Final Cut when I did this same process a few years ago).

So now, when I scrub through my clip I can see the different frames that make up the animation. Thanks again Jeff!

[Ben Mears]

Ok, I finally got it figured out. The Export Settings window was located off screen (apparently in a kind of no-monitor land).

Here’s how I got it back in view:

-Hit Alt + Space
-Hit the down arrow once (to select “Move”)
-Use the arrow keys to move the window back into view.

I’ve never really experienced a window being open but not visible because its hanging out off screen so I think that’s why I got so confused.

Thanks guys and I hope nobody else runs into this and gets as stumped as I did, ha ha.
