Black frames at end of render

I'm creating 10 second video loops for playback on a website. But when I export the video, it seems to be adding a black frame at the end of the render, so it skips when it loops.

I've created several of these videos just fine awhile back with the same file, and same preferences. The problem didn't start until I updated to CC 2014.

Anyone have any ideas? Am I just missing something in my render dialogue box?

    Hi Kevin,
    Hope you have a great week so far.
    Can I ask you why Adobe doesn't fix this issue of adding an extra frame when setting an outpoint?

    It happened to me multiple times when I assume that by skipping to the end of clip I set the output at the end of clip then forget adobe adds an extra frame. During broadcast rehearsal we end up going back to editing suit because of this.  I've made this mistake enough times to learn but still when deadline is pressing and pressure is high it can still happen. 

    What is the reason of adding an extra frame? 


    Hello @Tobiasz23517314g5xu,

    To be honest, Avid and Final Cut does this too. The key is to avoid setting the out point using the Playhead as a guide. If you do, go back a frame, then mark out!

     

    Why is it that way?

    The Playhead represents an entire frame, which has a head and a tail. It is not a "needle," even though it appears that way when zoomed at a normal Timeline zoom level.

     

    If you zoom way in on the playhead, you can observe and understands why it behaves as such, and why you need to step back a frame when using it for marking out on a clip. It becomes a habit after awhile.

     

    This is a "gotcha" that was taught to me in trade school when I learned Avid in the 90s. If you didn't take Avid 101, or a similar intro class, most editors have a "smack my head" moment the instant they discover that they've been mistakenly trimming off the head of the incoming frame of the following clip for years! 🙂

     

    Actually, Avid has this feature where you can hold down the Ctrl/Command key to snap the playhead to the tail of the final frame of a clip, rather than the first frame of the incoming clip (and perhaps Premiere Pro should also have this feature). Otherwise, it's the nature of the beast and the way the Playhead is designed across every NLE I've ever used on the market.

     

    When marking a clip rather than the last frame of the sequence, use the Mark Clip function instead of using the Playhead to mark Out. It sets a mark out as you'd want it to be.

     

    Hope the info and the context helps.

     

    Thanks,
    Kevin

    I know the answer to this - when you export to save do this: file / export / media / the trick is here - see the timeline under your video - amend the time so that it matches exactly where you want it to end - thats it! voila!  :-)

      I found a solution! So if you're exporting from the Adobe Media Encoder you can do this (you can run your video through the encoder after you've exported it as well):

      Right click on your video in the Queue (that Instagram Video is my preset so it may say something different on yours such as "Match source - high bitrate):

      Click Export Settings.

      Then. under your video preview there is a timeline that shows the duration of your video. If you move the far right notch over to the left a few frames before the end of your video it will only export the video length within the blue timeline; thus eliminating the final few black frames.

        Keep having the same bug over and over. Tried to mark the Out point 1 frame behind in AE and in encoder.
        The output seems to be random. In some renders I have one black frame, in other I don't.
        I don't understand this lack of precision for such a simple task coming from a company like Adobe.

        I found out at least one way to solve this problem.

        I export videos without audios, and when the tick "export audio" is selected, there is always a black frame at the end. When it's not, everything is ok. Hope it helps someone.

            Hi Cody,

            I saw you did have one answer but here's another solution - It may have to do with the options you chose at the beginning. Try this:

            - New Project

            - window pops up where you name the project

            - New Sequence window is next (this is where you designate the frame size and will get rid of the black frame or borders - pillow boxes or letter boxes)

            - When filming I use 29.97 frames per second and I then chose:

            - Digital SLR

            - 1080 p

            - DSLR 1080p30  (the 30 at the end stands for the 29.97 frames so if you've filmed in 24 or 25, chose that ending).

            You will now see at the left in "Video Settings" that is should have the Frame Size as 1920h x 1080v  and the Frame Rate will be whatever you chose.

            I know this is an old discussion stream but it didn't looked like it could have used a more complete answer.

            Hi Cody,

            If you tend to use the Playhead for marking an Out point in a range, you will add a frame of black. To avoid it: after the last clip in the sequence, move left one frame and then mark Out. You are including one frame of black by not doing so. You now have an export without the black frame.

            Hope that helps,

            Kevin

              Thanks for the response, Kevin, I've tried this and it's not the problem. No matter where I mark the in or out—or even if I don't mark them at all—it still adds the black frame.

              Now this is where things get interesting. The more I tweak my export settings, I'm finding this only happens when I export as H264. If I export as Quicktime, but with an H264 codec, it's fine.

              I feel like it has to be something in my render settings?

              I just did a test and there is no black frame on my export. Can you try again with a new project and different media?
