 Good afternoon!

 I'm attempting to use FFmpeg to convert a DVR-MS file into a MP4 file; I'm
 using the following command to perform this action:

 ffmpeg -i "xyz.dvr-ms" -y -c:v libx264 -crf 23 -strict experimental -c:a
 aac "xyz.mp4"

 After the conversion completes, and I play the MP4 file in QuickTime to
 view it, I note that the video "judders"; that is to say, the images don't
 flow smoothly, as it appears as though every other frame is missed.

 I've uploaded a copy of the debug log from the conversion attempt, as well
 as a sample of the original dvr-ms file (I've named it "no_judder.dvr-ms")
 and the resulting output file from the conversion attempt (named
 "judder.mp4"). The size of the log was too big for me to include in this
 ticket description. Any assistance you may be able to provide would be
 greatly appreciated.
