    HD2SD Dan Issacs's Method..help

    lou4uandme

      Hi all,

      I just followed the instructions from Jeff Bellune video tutorial. I Installed all of the Hd2sd, Virdub,etc...

      I still have a few questions :

       

      My Workflow is this:

      Canon XHA1 24p into Premiere cs5     (progressive right?)

      Render out an Mpeg-2 with preset from website (I-FRAME mpeg)

      Use "Rendered file" with this  script:

       

      MPEG2source("1080p30.d2v")
      hd2sd(interlaced=false, OutputColorSpace="YUY2")

      -------------------------

      Load it into VirtualDub

      Compress with Larithe (forgive spelling)

      ------------------------------------------

      Import "Rendered AVI" file into ENCORE

      ----------------------------------------

      Questions:

      So this AVI file in Encore has to be Transcoded right?

      Are there any special settings I need to make?

      In the I-frame Preset (1440 X1080 24p), it is set to CBR-100

      I thought Varable 2-pass is better? Why is it set to CBR?

       

      -----------------------

      NOTES:

      I compared my usually DVD render with this method

      and I could not see any difference . Perhaphs a Little, little, tiny bit when I zoom up 400% in premiere

      but on the TV, I see no difference.

      I just want to make sure I am doing everything alright.

       

      Am i?

      Thanks,

      Lou

          Apparently, CS5 got a lot better at this than CS4 did.  It was the failures of earlier Premiere versions that sparked Dan on his quest for a better method.

            So are you saying that anyone with CS5 doesn't need to go thru all of those steps?

            That the results are equal to Dan's?

            (I know I said when I compared they looked the same)

            but I thought it was because I was doing something wrong(as usual)

              That I can't comment on directly, as I'm still working in SD.

               

              But others here seem pleased with the improvements to the process in CS5.  Perhaps someone with direct experience will chime in.

                Hey Lou,

                 

                I have to agree with you. I just created a SD DVD from HD source from FCP-->Compressor-->DVD studio Pro, the edges of the picture looks jagged. Then I tried Dan's method, output video file from CS5 in MAC with the i-frame MPEG 100Mbps as instructed in Dan's Issac method and load it to PC. Use DGIndex, AVISythn and then Virtual Dub to create Lagarith AVI, everything looks great until I export the AVI back to MPEG-DVD for Encore. End result is actually a little worst then what I've done via Final Cut Studio 2.

                 

                Also the Virtual doesn't carry the 16:9 pixel aspect ratio over to the Lagarith AVI, I had to manually stretch the avi in Premiere. I try that "widescreen 0, etc..." code in AVISynth, it didn't work.

                 

                I'd spent days testing all possible rendering in AME and then Encore, not much improvement.

                 

                Anyone have input to this?

                 

                Thanks,

                  Lagarith and UT don't put PAR information in the AVI file (AAMOF, PAR info may be missing from any AVI file, but I can't be sure of that).  So the video was created correctly out of VirtualDub, but you won't see the correct PAR until you go to File | Modify | Interpret Footage in Pr and set the correct PAR there.

                   

                  Manually stretching the AVI in Pr is what ruined your output quality.  Interpret Footage is the proper way to set the correct PAR in Pr.

                    Hi Jeff,

                     

                    Thanks for the prompt reply, I will try the set the Pixel Aspect Ratio from Premiere and let you know whether it works.

                      Hi Jeff,

                       

                      There's one problem, the image looks fantastic! I've clean edges on my picture. Without clean SD image for DVD, there is no point to shoot in HD.

                       

                       

                       

                      Thanks,

                          Hi Jeff,

                           

                          New problem after I upgrade my system to Win 7 64-bits.

                           

                          • AVI Import Filter error: (Unknown) (80040154) - solution: A missing dll might be the problem: msvcr71.dll msvcp71.dll should be in the windows\sytem32 directory or windows\SysWOW64 (Windows 7 64Bit)

                           

                          I looked into the MT Support page but the solution section is kinda confusing. I find the msvcp71.dll file from my CS 5 installation folder, do I just copy and paste the same file under SysWOW64 folder? This sounds too strange. If I don't have CS5 installed then where would I locate this file?

                           

                          Thanks,

                          Albert

                            Hi Jeff,

                             

                            I copied the msvcp71.dll file from the CS 5 folder and paste it to the SysWOW64 folder and tried to run the Virtual Dub with the AviSynth file. It doesn't work, the burn in subtitle has jagged lines.

                             

                            Please advise what can be done about the msvcp71.dll file for Win7.

                             

                            Thanks,

                              One more thing, the MPEG2 i-frame source pane shows pixelated image in Virtual Dub. I wonder if this is due to wrong setup with AviSynth, MT 0.7 or Virtual dub in Win7 64bit

                               

                              Please shed some light.

                                I noticed after running a 1280x720 @ 23.967 .m2v file through VirtualDub using hd2sd that the resulting .avi file was displaying a 3:2 aspect ratio in GSpot.  Does this mean I screwed something up or is this normal until after I encode to MPEG (using HC Encoder) and import into Encore?

                                  Sometimes getting the right PAR from an AVI file is problematic.  Just make sure that Pr sees it as720x480 with a PAR of 1.2121 and you'll do OK.  Use File | Modify | Interpret Footage to force the correct interpretation if you have to.
