    H264 encoding in SD causes import error

    schlossd Community Member

      When I export from the timeline that is HD to H.264 for SD I get an error saying that Quicktime or other codecs could not be located.  But I did this before with another clip and it worked just fine with the same settings?  Could I have blown out something on the program?  Should I reinstall encore?  The segment in Premiere is 1 hr 15 minutes and I need to compress it down to fit with other HD to SD files.  So far H.264 looks great but this one clip will not import without the error poping up.

          I don't know why you may be getting the error, but I have to ask first if you are building a DVD or Blu-ray?

           

          If DVD, why you are using H.264-encoded files as a source? Do you know that they will be re-encoded to MPEG-2 before being burned to DVD, thus enduring a second round of compression?

           

          It's far better to scale it down in a standard definition sequence in Premiere, and then export it using MPEG-2 for DVD settings.

            Thanks for getting back with me.  I am creating a DVD.  The reason I am using H264 (and know I wonder if it was wise) I am trying to reduce the file size so it will fit on the DVD.  This is a very large wedding that went to 2 DVD's (both BluRay and DVD) the problem is I cannot get the last file on DVD, it is 1.3 gigs too big, I was hoping to reduce the size without removing content.

              All video on a DVD is encoded to MPEG-2, regardless of which other video format you bring into Encore. What is important is the duration of the video, not the file size (unless it is already transcoded to MPEG-2 for DVD).

               

              If you compress a file as H.264, it will get re-transcoded to MPEG-2 before being written to DVD. This is not good if you want to retain video quality. It is better to give Encore either MPEG-2, the original capture codec, or even uncompressed video.

               

              You can set the encoding bit rate lower and squeeze more on the disc - at the expense of video quality.

               

              Have you considered burning a dual-layer DVD?

                Yeah thats what I ended up doing.  Thanks for the info I will keep this in mind for the future.
