<div dir="ltr">Well this whole commercial removal is proving to be a lot more difficult than i could have imagined... <div><br></div><div> i removed a splitter and changed my a cable amp and got my signal level up to ~6db on average, tried two new recordings and lossless cut failed on both with an error during the mkvmerge</div>
<div><br></div><div>"Error: Found B frame without second reference in a non closed GOP. Fix the MPEG2 video stream before attempting to multiplex it."</div><div><br></div><div>Not sure whats up with that.</div><div>
<br></div><div>Back to trying Avidemux, I found that adjusting the audio sync worked great and went to make my first commercial free video with avidemux2_cli. I immediately ran into an issue where i set the first segment to frames 60-23307, when I run the command it tells me that frame 23307 is a "b" frame and it wont let me end on that frame. Whats weird is that with the avidemux GUI i can select that frame and it tells me it is an "I" frame. I never would have thought that with all our technological advancements there isn't an easier way to chop pieces out of a file... lol. I guess I will give up for now.<div>

I never found that Avidemux v2.5x could handle HDPVR 1080i recordings. Iregularly compile the Avidemux beta version v2.6 or sometimes called v3.0 (e.g. just last week). That version does very well with HDPVR 1080i recordings. Its downside is that the GUI is not always functional(e.g. the mouse scroll wheel always goes backward on the time line). It sometimes can edit a recording with defects that other tools including the olderAvidemux and mkvmerge cannot handle. I basically keep it in my bad of tricks.<br>
<br>
As for Avidemux CLI, the idea was to have a script like Lossless Cut generate an Avidemux "js" or "tinyPY"project file from MythTV cut listinformation then use Avidemux CLI to perform the cut and merge processing in lue of mkvmerge. Without the automatic generation of the Avidemux project file you may as well perform manual edits in the GUI and let it do theprocessingthrough a save.<br>
<br>
As far as audio sync is concerned the Avidemux v2.5x had a consistent audio delay of 340 milliseconds with my HDPVR recordings which I corrected by washing the lossless edited video through mkvmerge CLI with a video sync delay value of340 milliseconds. With Avidemux v3.0 there no audio sync issues in the saved lossless cut videos. It should be noted that ffmpegcan be used to change the track sync as an alternative to mkvmerge.<br>
<br>
There is, on the MythTV wiki, an unsupport Avidemux project file generator bash script but it will not work with beta Avidemux v3.0as the project scripts have difference syntaxthan Avidemux v2.5x. In fact I was trying to update that script before venturing into Lossless Cutdevelopment. The original developer of the script has left the project.<br>
