    CS4 crashes when working with 720p clips

    juskocf Level 1
      The 720p clips were taken by a Panasonic DC with movie feature and the format is motion jpeg (xxx.mov). I used to edit the clips with CS3 without any problem. But now with CS4, which crashes even after some scrubbing and playing. I have tried formatting my harddisk and reinstalling vista and CS4, but still the same.

      Any idea please ?

          The only suggestion I can offer is to make sure you're running the latest version of QuickTime.

            Hi, Wil, yes I am running QT 7.5.5 which I think is the latest.

              I have the same problem...
              No need to import any video
              Just create a project..
              Add a 720P(1280*720@30fps) sequence..
              And click the sequence to open in timeline window..
              It just crashed...
              But it goes well with timeline window closed...
              btw, I'm running the latest version of QT.
              I'm now running a project which is 720P
              And it didn't work at all.

                Just wasted an hour trying every flavor of export available in AME. 99% crash ratio. First thing that is glaring is that all the presets are DV.

                Next thing is that if you stretch the aspect ratio to 1280, the constrained proportion becomes 853 not 720.

                I did manage to export once at that ratio using 29.97, lower first, 8-bit and of course it looked like crap with huge blocky pixellations in sky areas, etc.

                Will not export as 30 fps, will not export as progressive, will not export 1280x720.

                  What do you mean "all the presets are DV" ?

                  How and where are you "stretching the aspect ratio" ?

                    Yuwei, I created a sequence with the settings you mentioned and do not experience any crashing. I'm running CS4 under XP x86 and Vista x64.


                    Cheers

                      @Craig Howard:

                      AME Export Settings

                      Format: Microsoft AVI

                      Preset: All selections are DV

                      Setting up a Custom Preset:

                      Video Codec: LEAD MCMP/MJPEG Codec (2.0)(VFW)
                      Codec Settings:
                      JPEG 4:2:2
                      Quality: 64
                      Interleave: default
                      Decompression: Enable

                      Basic Settings:

                      Quality : 90

                      Width: 1280 and if Constrained is selected, it defaults to:

                      Height: 853

                      (If I unlock the constraint and make it 1280x720, it CRASHES)

                      Frame Rate: 30

                      Field Type: Progressive

                      Aspect: Square Pixels (1.0)

                      Render at Maximum Depth

                      Audio 44.1kHz 16-bit stereo or 48kHz, 16-bit Stereo Makes no difference.

                      CRASHES, CRASHES, CRASHES.

                      I was able to get one interlaced encode at 29.97, lower first, that looked dreadful. Blocky, pixellated, ugly. That is the only time it has ever completed making an avi file that played. A Microsoft RLE codec completed the output but would not play in Windows Media Player.

                      And here's the thing:

                      Using the same footage with the same codec I am able to get beautiful Hi Def 1280x720p, 30fps, square pixel, 44.1kHz avi file exports from PREMIERE 6.0! Everything is the same except AME, so it's not like there is no baseline or background upon which I'm basing things.
