Todd: what a spot on and truthful comment and reply.

I’m planning on going back and shooting another test, this time with the camera Shutter setting on LOW. This allows me to dial in slower shutter speeds from 1/30th down to about 1/4. Maybe one of those speeds will reduce the rolling white bands I get.

If I shot individual clips at different slower speeds, I could note those speeds by speaking them into the onboard mic. (I don’t think shutter speed is recorded as metadata with the clip.)

I have a Marshall Electronics monitor that fits on the camera’s hot shoe – it’s not very big, maybe 5″-6″ wide, but I’ll try that and see if it shows the white banding. How big of a field monitor do you need to show a flicker problem like this?

The bands, BTW, are really soft-edged, not hard like you see in some situations.

Thanks again, Todd.

Thanks, Jeff.

I was in a rush to complete some training vids using someone else’s 4K files, shot on this Red camera I mentioned.

Normally when I start a new project in Premiere, I simply drag the imported clip into an empty, undesignated sequence that is available when you create a new project. That way, the sequence is exactly what the CLIPS are, in terms of dimensions, frame rate, PAR, etc. That’s just a habit I created.

Next time, I’ll import my clips and create a new UHD sequence, like you suggested.

Thanks again.

Well, that makes sense, David. ????

Problem is, I’d have to scale down all of my 4k clips to fit a 1920×1080 timeline – very time consuming, considering my project is done.

Also, I believe this particular camera doesn’t shoot files that are exactly proportional to 1920×1080, it works out to be 1920×1010.

I’ll have to figure something out and I’ll reach out to the team who shot this Red camera.

Thanks again.

Thanks, David.

Customer wants a smaller file, for use in a CBT training course. 4k is way too large.

My timeline and clips are all 4096×2160, exported to an MP4 at 1920 wide.

I cannot see these small black lines on the left or right IN THE TIMELINE. They only appear in the rendered file.

Render dimensions settings (scaled down) are 1920×1010.

Still trying to figure out where the black lines come from. These clips were shot on a Red camera, I’m told.

Thanks again.

I believe you’re right, Mark.

>Camera-generated bars are next to useless; you need a chart shot thru the lens, under the actual lighting conditions.

I’m using a Macbeth color chart AND a Kodak grayscale, but I think I’ll start relying on my waveform monitor. The chart and grayscale card are mounted on a stand, where the subject would sit, under studio lighting.

I assumed there was a correlation between the 70% step on the grayscale and the 70% that the zebra stripes represent, but there isn’t one.

70% zebra stripes represent 70% brightness, not 70% on a grayscale.

Thanks.

Thanks, George.

I’m so used to internal physical drives for source clips – I’m a bit behind the TB2 wave so using external drives for accessing clips while editing is a little foreign to me.

And another vote for editing with Premiere Pro on a MBP, also. That’s good to know. ????

TB2 drives are still a bit pricey, so we’ll have to wait for now and continue to use USB 3.0.

Thanks again, everyone.

Wow, thank you, John. You took the time to respond succinctly and I will consider a newer Mac Pro that you suggested from OWC.

I’ve been doing some reading on USB 3.0 vs Firewire and for now I’ll go with USB. I don’t have any 4k footage to deal with, so USB should be fine. I wasn’t even aware that the new Mac Pro’s didn’t come with FireWire.

Thanks again!

It has nothing to do with your footage having no audio – I changed this setting and my problem instantly went away.

Just found it!!!

I went into Edit > Preferences > Audio Hardware and then changed Default Input to “No Input.” It was set to the input of my sound card, which currently has no device plugged in to it. Not sure why that would cause it, but as soon as I changed this I was able to preview the video file with no stutter in the playback.
