Increasing the I/O Buffer Size to 2048 will make more RAM available to playback audio which should help keep things synced.
There is also a setting in the Adobe Premiere Audio Preferences that can improve audio playback. Thanks for your help jsbarrett, to answer your question I see the missing frames when stepping through each frame, I did figure out the problem thanks to this handy video you sourced me, the problem is that I was importing video files that used a variable bit rate, I fixed this by converting it to constant bitrate using TmpEngc, but it looks like handbrake will work as well. dif doesn’t work, another way to fix this is to convert your video with Handbrake set to a Constant Frame Rate (CFR) before importing it into Premiere. dif and press Enter to finish editing the name.Ĭlick Use. Single click on the file and press Enter on the keyboard to edit the file name.Ĭhange. mp4, this will cause Premiere to read it correctly. This is related to not reading part of the mp4 file during import.
Adobe Premiere does not do this automatically, so you can run into playback differences that are dependent upon your video source. This normally does not present an issue because iMovie and Final Cut automatically compensate and re-render the video at a Constant Frame Rate (CFR). Instead of being an exact frame rate like film at 24 frames per second (fps) or 30fps, the camera can save the video at rates like 29.910988 or 29.970030 to save space. This can cause the MP4 file audio to play out of sync when editing in Adobe Premiere.
Digital video is sometimes recorded with a Variable Frame Rate (VFR).
