ProjectX doesn't work with H.264 video streams. mp4 - these sometimes have weird lengths and/or you can't seek properly through them.ġ. If the stream has errors, avidemux will fail ("video too short" - most likely pts/dts errors). If the stream is error-free, avidemux will chop it neatly. Okay, using this as a diary/scratchpad - you never know, it may be helpful for someone else! - here are my conclusions so far:ġ. (Yes, I've tried comskip - Windows and Linux - but it struggles to identify most ad breaks and I end up tuning/doing the cut list by hand yes, I genuinely do like to cut out the fluff and have a programme that starts where it should, end where it should, and doesn't need skipping around in the middle. Thoughts or comments? Any blow-you-away suggestions or improvements? avi (avidemux's default) but that was a disaster in VLC and Parole - I don't think H.264 and. mkv as the seeking is probably better supported. Leave the bloody thing alone and stop wasting my life fiddling with video files Trim pre- and post-amble (commercials in the middle TBD) 4. Avidemux always used to have issues with MPEG-4 so I abandoned it when I moved off MPEG-2 - but a clean compile of 2.6.7 today seems to work well.ġ. So, I've lurched back to avidemux (having stumbled on the way through ffmpeg, mencoder, mplayer.). keyint=25:min-keyint=13 to give half-second accuracy) but (a) the files now obviously get bigger and (b) the encoding takes even longer. Yes, I can increase the I-frame frequency (e.g. That means 5-second accuracy on a 50Hz file, and that makes for ugly cutting. Utter nonsense.ĭownside 2: HB uses x264, which defaults to a GOP of 250ish. ![]() Even on a quad-core i5, I'm spending up to 8 hours to re-encode a film. settings to trim while encoding).ĭownside 1: It takes f-o-r-e-v-e-r. It marginally shrinks the files (HD H.264) but produces something that mkvmerge can slice up (I've never got on with HB's encode from. ts files won't chop neatly in mkvmerge because of errors, so I tried ProjectX and a couple of other things before landing on re-encoding completely in Handbrake. where audio switched from a stereo continuity announcement to 5.1 during the main programme). But I dropped that last year in favour of. mkv as the target tvheadend recording format, because mkvmerge could chop those up nicely. I've been around the houses on this for some time, so I thought I'd see if anyone else has a foolproof method of processing their files.
