Footage exported through Adobe Media Encoder has red frames.
If no other source is available, then one or two frames can be fixed by copying neighboring frames. Use the location of the red frames in the export file to help track down problems in the source footage. This issue is not a failure of the export process, but rather an indication of a problem with.
Either obtain new clips or repair the red frames by copying neighboring frames.

This issue is not a failure of the export process, but rather an indication of a problem with the way the source footage was encoded. When Media Encoder encounters frames that cannot be decoded, it inserts red frames in their place.
The red frames serve two purposes. First, they keep the audio/video sync intact. Second, they make it easier to track down the location of problem frames. When a frame cannot be decoded, it is logged in the Events panel.
In the CC version, more strict format constraints were implemented, allowing the software to better detect and flag file corruption. In past versions, these problems could have been missed, causing crashes or failures when encoding the final project.
The red frames occur most often when using MPEG-based footage, and often indicate a problem with the GOP structure. Occasionally, with MXF files in particular, the footage could play in another application like VLC without any issue. The MPEG stream is intact, but the MXF index table was written incorrectly when the file was created. The software can't locate the proper frames according to what is specified in the index table, so it replaces those missing frames with red frames.

A quick change of your poster frame can help you better organize your editing workflow in a big way. Find out more in this Premiere Pro tutorial.
In Premiere Pro, the default poster frame (or thumbnail) for your clips is the first frame of your selected video. While this may work for some videos, usually the first frame is not a great indication of what is going on in the clip itself. This can result in wasted time spent searching for the right video when a quick thumbnail change could have prevented the entire mess. This is especially true when working with multiple editors.
The clips on the right are the same clips as the ones on the left, but with different poster images.
In this quick Premiere Pro tutorial, we’ll show you how to set the poster image from the default first frame to a frame of your choosing. Let’s begin:
1. Set the Project Panel to Icon View
By default, your project panel is probably in a list view, meaning all of your assets are listed without a thumbnail image. If you want to be able to see your poster frames, simply click the icon view buttonat the bottom left hand corner of the panel. You should now be able to see a visual thumbnail of all your clips.
2. Find Your Desired Poster Frame
In the icon view, you can scrub through your video files two different ways. The first is to physically use your mouse to scrub over the video from left to right until you’ve found your desired frame. The other is by selecting the clip and hitting the spacebar. You can use the same playback controls as the preview monitor, so keyboard shortcuts like J,K, and L work as well. Once you find your desired frame, simply hit the spacebar to stop.
3. Right Click
With your desired poster frame selected, right click on the video thumbnail.
4. Set Poster Frame
In the dropdown menu, select Set Poster Frame. The current frame will now be your default thumbnail in the icon view.
