Premiere Pro Cs6 BLACK BAR under rendered files in viewer
Greetings,
I just switched over to PP after being a FCP editor for years so pardon me if I use FCP terms.
I have an open sequence and when the clips in that sequence are non-rendered (red bar up top) they appear fine. However once I render the clip a thin black bar appears under the clip in the viewer. This happens to every clip. I checked the see if this carries through an export and thankfully it does not, that that leads me to believe that this is a problem with the “VIDEO PREVIEWS” PP says it is generating when it is rendering.
Even though this is a minor thing I can forsee having to re-encode something because I am not looking at an accurate representation of my sequence. Below are some screen caps to illustrate what I am talking about.
The regular frame how it should look and does look before rendering.
How the frame looks after rendering.Thanks,

Can you tell us your sequence settings and the media specs?

Hey Tim,
In trying to answer your questions I accidentally resolved the issue. THANK YOU.
Turns out the problem was that the preview video files were rendered with iframe. I switched it to “Quicktime Desktop” and poof the problem was solved.
Thanks again,

I was guessing that the frame dimensions may not come out at an even multiple for MPEG…I seem to recall the magic number being a multiple of 16…?
Anyway, when I saw the issue, that was the first thing to jump to mind…

Tim,
Since we are here and talking about this am I correct in assuming that these “Video Previews” have nothing to to with the over all quality of the Master?
For example if my source footage is Prores 422 4:4:4 and I set the preview codec to DVCpro50 NTSC I can still export it at a Prores 422 4:4:4 without any downres/artifacting?
I believe this to be correct but I want to make sure I understand how PP functions.
Best,
D.M. Rosemark

Yes, previews and master are independent unless you choose to “use previews” during export.
One bonus of using ProRes as your preview is that you could use the previews on export to ProRes and in CC, it will skip re-encoding.

Yeah these are big files and it just seems like using a prores as a vid preview is going to be too taxing on my system in the long term. The render times are shorter with P2 and the Rendered files are smaller.
Thanks Tim, this is why I always turn to CC when I have to trouble-shoot.
