    Choppy motion on HDTV but not Laptop / PC


      Hi everyone. I recently created a short movie that plays smoothly on my laptops / PC on multiple H.264 settings exported at 24fps. Unfortunately, seemingly no matter what settings I export at, the same clips become quite choppy on my HDTV's. Walking almost looks like teleporting.


      Just as a little more info, I've played multiple other MP4 videos on these HDTV's and they run smooth. My setup is I'm playing the file through my laptop and connecting it to the HDTV through the HDMI cable. Any guidance would seriously be appreciated.

          Can you post a screenshot of the export settings?


          Also, many/most HDTV displays cannot handle a native 24p signal (23.976) so the laptop is likely putting out a 59.94 or 60fps signal so there is some interpolation of frames going on and that may be the issue you're seeing.

            Hey thanks for the reply Jeff! Here's the last export I did:



            Frame Rate: 23.976fps

            Field Order: Progressive

            Aspect: Square Pixels (1.0)

            TV Standard: NTSC

            Profile: High

            Level: 4.0

            Birate Encoding: VBR, 2 Pass

            Target Bitrate: 5Mbps

            Maximum Bitrate: 5Mbps

            Key Frame Distance: 24

            Audio Format: AAC

            Audio Codec: AAC

            Sample Rate: 44100 Hz (this matches the sample rate of the imported MP3, and in turn the sequence setting as I've set it)

            Bitrate: 320 kbps


            I just noticed that even the source videos from my Canon 70D camera have the same choppy motion through my Philips HDTV's. Also tested through my friend's laptop and HDMI to make sure i wasn't going crazy. Have a good one. Let me know if any more info could be useful.
