Jerky render Hitfilm Pro 2017

Sorry. My first post seems to have vanished.

Perhaps I am doing something wrong with my set up; but, look at this Hitfilm render. it is a 720p clip at 29.97 fps level 5.1. NOTHING has been done to the clip other than to trim it. Exported as an h.264 in an MP4 container.

 

The clip is noticeable jerky, like there is a mismatch in the input and output frame rates and some frames have been dropped or duplicated. Contrast that with the resolve clip done the same way.

 

Anyone else experience this or have a thought on how to correct it?

    Can you give us a MediaInfo report on the original clip?  It does look like a botched frame rate conversion but I can't say for sure without knowing what the original is.

    Ok I'm at a loss for the moment.........

  • Maybe @Triem23 will come along with a solution.  The jerky output is pushing me to other compositors and NLEs........

  • test the same with constant bitrate..

    wich player do you use? vlc oder windows-player? its the same with other player (f.ex. windows-classic-player)?

  • It's the same with every player.

  • Have you tried installing  K-Lite Codec Pack?

  • @Yeremyah. Not certain which codec Pack you actually are referring to, but my system has the appropriate codecs to render and play these avc1 files

  • I had an issue once like you describe, and I did have all the codecs installed, but I installed the  K-Lite Codec Pack anyway and it seemed to fix some things for me.

    Bob I've encountered this issue too, but I think it's fixed internally and the fix will be in the next update. 

  • I  entered a support ticket and Axel asked for the files. While preparing to comply with the request I made another interesting observation. The jerkiness seems related to the length of the clip you upload to the media bin. My original clip was over an hour. When I trim that on the timeline to a minute and render it, the jerkiness is seen.  If I cut that same minute from the original using Convert V4 and load that short clip as media and render it on the same exact timeline with  the trimmed clip from the full length video, it renders smoothly while the trimmed original remains jerky

  • Here is the render example I note above.
