after editing a project (shot on Canon 5D Mk II) in Adobe Premiere Pro (CS5.5) on a PC, the customer demanded two versions of project.
I used Adobe Media Encoder (CS5.5) to export the project in a resolution of 1280x720, 25fps, 2,16Mbit/s which worked perfectly fine and also really fast.
The second version, however, exporting from the same Premiere Pro sequence, was 960x540, 25fps, 800kbit/s. At one certain point during the movie it seemed like one edit just had been skipped. I then tried exporting a Quicktime Movie using the Animation Codec for further encoding but the result was always the same. I used Sorenson Squeeze, Mpeg Streamclip and as mentioned Media Encoder. Changing the interval of keyframes did not help.
I even used the bigger WMV to create the smaller one, no success. Btw the rest of the movie always played back fine.
In the end I was able to export the smaller WMV on a Mac using FinalCutPro (!!!). But even there the "skipped" edit was not shown correctly as in the 720p-version.
I'd be really thankful for any suggestions for what might be the issue.
