Possible to move item on timeline by half a frame?

Hi

I have found audio desync in source footage from twitch that appears to have audio offset by n.5 frames. I can move my desired sound to a half a frame before or after by not exactly the point I want as the minimum timeline shift appears to be 1 frame... any advice or will I just need to take to to just before / after the video queue that I want?

The peak I want sits between the 2 key frames on the audio track frames (key frames used for visual guide only). Oddly, moving 1 more step / frame to the right also causes the the audio to shift within itself (or maybe the key frames do their own thing.. not sure..):

Any input appreciated, thanks.

    Move the cue early. You cannot move anything by half a frame.

    Your other option is to double the frame rate of the project - i.e. From 30 to 60. This will give you additional temporal resolution but it will slow your render as you'll be rendering twice the frames.

    Hi Triem

    Thanks for taking the time to reply.

    I'm already at 60fps so I guess I'm stuffed then and will have to make do with flash --> bang.


    Best regards

    On closer additional inspection, the audio is actually shifting at a minimum resolution of 2 fames, not 1. This can actually be seen in the previous images, i just hadn't noticed... is this a limitation? The video was 60fps from source, 44100 hz


    Is there any additional advice you could give?


    many thanks

    Damn it.. I'm gonna answer my own question! Not because I'm grumpy because my answer wasn't handed to me on a platter, but because I'm dumb and missed the obvious. So the audio only moves in 2 frame steps?? Well the move the vid by 1 frame Lax, you moron! :D


    Funny how you get target fixated on 1 fix..!


    Again thanks for your time

    I do my audio editing in Reaper instead.

    You get much finer control over the audio position and more powerful tools for audio editing

    You can load a video file and display it in reaper to align your audio. I find it much easier to do my sfx and fey there than in HitFilm.

    Here is a random video about using reaper like I do.
