  • Edius Pro 4.51C and smart render?

    Hi,
    I have a MPEG2 profile setup in the export section. We use 8m video 256k audio. Is there a way to tell Edius not to re-render the output file from the timeline if the file on the timeline complies with the profile settings in Edius already?
    Example
    I bring in a mpeg2 file that had already been encoded that way and we just using Edius to edit the file. The Original file is encoded to MPEG2 8m video and 256k audio same as the profile in Edius. Now I clean up the clip cut the front and the end of the clip so its a clean show. I print to file to the MPEG 2 profile. Is there a Smart Render feature that will only re-render a file if its not at the MPeg2 profile setting? As it is it seems like a one show will take about half time or so to render out and I thought that it would be faster since we not modifying the parameters just editing the file.
    Thanks.

    Yes, with caveats that:
    1) You must use the EDIUS-native MPEG exporter (not ProCoder Express for EDIUS)
    2) You must enable the SegmentEncode in the MPEG exporter
    3) The native MPEG exporter doesn't support 720p at this time

      I'm new to this software. How do I distinguish between Native mpeg exporter and proCoder? All I see is print to file and I select a MPEG2 profile I made there. In other words can you please elaborate step one. I see where the segment encode is enabled already.

        When we say "native" we mean that you're using one of the EDIUS MPEG exporters that exists outside of 'ProCoder Express for EDIUS'

        Presently, this includes the 'MPEG (Generic)' and 'MPEG (HDV)' exporter.

        Smart rendering is also available with XDCAM MPEG-based exporters too.

        ProCoder Express for EDIUS MPEG encoding will never support smart rendering.

          The MPEG2 profile I made was off the MPEG Generic. And I do have Segment Encode selected.
          So I have a MPEG 2 file that is the standard we use 8mbps constant video and 256kbps for audio. I clip the beginning and end to clean up the program. When I render it out as discribed above I'm having the MPEG Generic profile set to the same parameters it just seems like it take a long time to output the file. For example its about 1 hr program takes 45 mins to output. It does not seem to be as quick as another application we use to use called Womble MPEG Video Wizard where if the profile and the timeline files match parameters it outputs through a one hour program in like 9 mins since its not reencoding. Either I am doing something wrong or something else is not happening?

            What's the source of the MPEG-2 content you're importing?

              The source of the MPEG2 content comes from an automated MPEG2 Recorder (C500) we use for our Master Control made by Princeton Server Group. It captures analog audio video to MPEG 2.

                It's possible that we'll need more data on the MPEG-2 stream that unit produces.

                Segment Encoding is very specific on what it'll accept and ignore, when encoding a new stream. Are you able to upload a small sample clip somewhere for us to play with?

                  I'll be glad to upload a 30 second clip that is recorded on the device. I just dont have anyplace to upload too. The form wont accept MPEG2 uploads so I try to upload a zip file and said invalid post.

                  to add something here. it might be nice to know what criteria segment encoding is looking for?

                    Also, the project settings must match the original streams as well. Essentially, everything must match and the clips must not be altered in any way (duration/speed, filters, etc) otherwise EDIUS is forced to re-render that part.

                      You can check source properties -- bit rate, size, field order etc...

                        Well that does not make sense. Whats the point if you can't clip the front and clip the end of an MPEG2 then output if Edius is going to see that as not matching. The parameters match.

                          I have check the properties of incoming MPEG 2 files and they match what I have set in the F11 export using the MPEG Generic as the template. Still export times of the clip are higher than I expected for a professional product. Don't get me wrong Edius is great in many other aspects just wished it really did smart render.

                            Sorry, I was a little unclear... You can trim clips. It's just when you change speed or add filters that EDIUS has to recompress.

                              Well there is no change in speed because they both show 8mbps Constant and audio is 256kbps. We dont add filters.
                              I talked to someone in tech support and I was told that Edius does not support smart render function. He said to try HDV SpeedEncoder but it actually took longer to re-output a trimmed MPEG because the parameters are fixed at 6.5mbps. I hope the writers of the software in Japan know about this so perhaps they can improve Edius.
                              Unless there something missing or I am missing something?
