Interesting Playback Anomaly

**Paul** · 01-16-2015, 11:52 AM

The video does not have an overly high video bitrate (~3Mb/sec) so I don't think the problem is a too high video bitrate causing the stuttering. So, it does suggest the actual video's encoding may have a problem in that particular section of the video so that your device's firmware cannot decode & play that part properly. You can test this yourself by pre-transcoding the video with Mezzmo and then try playing the newly transcoded video. If it works, then it does confirm the encoding issue. To pre-transcode the video, right-click on it in Mezzmo and click 'Pre-transcode Files'. On the Pre-transcode Files dialog, select your device and click 'Choose Formats'. On the Pre-transcode Formats dialog, select the bolded format and select the 'Force full transcode of all channels' checkbox. Click OK. Select the 'Pre-transcode files even if they match the devices supported formats' checkbox and click OK. Wait until transcoding has completed and then try to stream the video again. Hopefully it plays smoothly all the way through now.

I will give that a shot and see what happens. I will let you know,

So, I did as you suggested and that seems to have worked. Thank you for your assistance.
