I really appreciate the detailed response, thanks to you I've been able to figure it all out! Upon viewing the Vapoursynth Preview I noticed the total frame count was 4 frames shorter than what VirtualDub/Premiere reports, and after running my source through ffprobe I discovered it had four duplicate frames, each one of them within the range I was testing the encode on :| . After accounting for the removal of those in my audio stream everything works as expected.
Apologies for the confusion, this job at line 46236 was a separate one used to verify that the error was not isolated to just the 534-2911 portion of the source.
This was just me forgetting to input the cut frames, whoops.
It appears that for some reason there was a 167ms offset in the source that carried over to the transcode. Getting rid of it fixed this particular issue.
Ohhh, got it, guess I should've looked closer at that help panel haha.
Isn't the purpose of the "Overwrite Input PAR" in the Misc tab to nullify whatever the source says the PAR should be in the Base tab and replace it with whatever value is there? Or am I just misinterpreting its function?
Oh interesting, I had assumed it would treat the external audio the same as the temp wav that's created from the source when cutting or transcoding, good to know! Though in that case what's the point of the "Don't cut external audio" option in the Misc audio settings if Hybrid can't cut it?
Also sorry to go off on a bit of a tangent to the original question, but for each of the other previews on Base, Crop/Resize, Audio, and Chapter I get an error message saying:
I tried troubleshooting it using this thread and testing mplayer itself, but unless I'm mistaken (which is certainly quite likely) it seems that mplayer does in fact recognize that there's a video stream present.
Is there an additional codec I need to install for this or something? This technically isn't necessary for my current workflow but I suppose it'd be nice to have working. Let me know if you need another debug file for that.
Thanks again Selur, Happy Holidays!

that is nowhere near:clip = core.std.Trim(clip=clip, first=3746, last=19987)

Quote:Quote: Wrote:Override PAR to 8x9 (also doesn't save)Yes, that is a source specific setting, so it doesn't make sense to save this.

Quote:It's not that it refuses it, it simply doesn't support this or know how to do it. Hybrid assumes that the external audio source matches the video source it should create.
