Suggestions for solving jittery playback of AVCHD footage?

Posted by Marty Schlick on December 16, 2013 at 10:22 am

Howdy,

Been trying for a while to track down a solution to a jittery playback issue (as if frames are randomly held or skipped) when editing .mts files in PP.

Jittery in PPcc and also after exporting to whatever… and especially using Youtube and Vimeo export presets.

VLC media player plays the .mts source files smoothly right off the SD card or HDD/SSD… most of the time, occasionally there is a hiccup but nothing like in PP.

The clips that do this are pretty much all of the panning clips and shot in either 24fps or 60fps 1080p.

I have seen this now on 2 different systems with different collections of .mts footage out of 2 different cameras.

Mine is a PC (running WIN7 i7 3770K 3.5Ghz, 16GB, GTX 660) and the other is a more powerful Mac with 32GB RAM (accustomed to smoothly dealing with RED footage).

I came across an Adobe suggestion to convert to a UTVideo codec ( https://helpx.adobe.com/premiere-pro/kb/audio-video-glitches-avchd.html#id_49687 ) to deal with AVCHD… but it really didn’t give much helpful info beyond the link to where it could be downloaded.

I tried the suggestion, downloaded the codec suite, made a preset in Media Encoder and transcoded, but it plays even worse than the AVCHD does natively (VLC doesn’t recognize that codec for testing).

Does anyone have any suggestions on the best settings for the UT Video transcoding and/or hardware/software settings for the smoothest PP playback of .mts clips? I see in the forums here and elsewhere that lots of folks have various problems working with .mts footage in PP… I am hoping there is a functional solution beyond what I have unsuccessfully tried:

– updating everything (apps/drivers/etc)
– setting playback to 1/4 or 1/2
– rendering the sequance/timeline
– transcoding to .mp4/DNxHD
– clearing render files
– maximizing ram for PP usage
– closing all other apps
– importing the whole ‘private’ folder from the SD card (which I – – – can’t seem to get PP to recognize anyway, it only will import the – – individual .mts files as far as I can tell)
– changed power options
– turbo boost for the i7 on or off
– and some other trial-and-errors gleaned from the forums that I can’t recall at the moment

Any suggestions for what to try next or the proper settings for using the UT Video codec would be GREATLY appreciated.

Thanks/Cheers!

Hi Marty,
Which version of Premiere Pro are you running? Is it updated to the most recent version?

Thanks,
Kevin

Hey Kevin,

Thanks for the reply… just sat down in fact to see if I had any replies… and shazzam, there you were!

I have PPro CC and just updated yesterday, but it has been doing this since I had a trial version of PPro CS6

Have you experienced anything like it?

Again, this is only in the panning shots, all other AVCHD footage seems fine in PPro and after export to YT/Vimeo.

I am going to go out and retake some test pans, and see how it is doing today… maybe it will magically fix itself (crossing fingers).

Thanks!
