Help me with my understanding here.<br><br>Comskip is fed a mpeg2 file. It then generates a txt file with diff mark-in and mark-out points.

<br>Are there other tools that can do pure command line to generate the transcoded file under Windoze or Linux ?<br><br>-Narahari<br><br><div class="gmail_quote">On Sun, Jul 10, 2011 at 3:04 PM, JD <span dir="ltr"><<a href="mailto:jdp@algoloma.com">jdp@algoloma.com</a>></span> wrote:<br>

</div>Many formats do not require "re-encoding", rather you can copy the<br>
interesting parts out at file-copy speed. I know this works for MPEG2<br>
and xvid/AVI (provided you stay on GOP boundaries).<br>
<br>
Some media playback devices and software will work with "skip files"<br>
created by comskip. GB-PVR does and mplayer will too. There must be others.<br>
<br>
90% accurate commercial removal (or marking) is possible. A little<br>
googling will teach you loads. The key steps are:<br>
- MPEG2 files as input (this is key)<br>
- comskip to locate commercials - comskip runs well under WINE.<br>
- Software that can use one of the comskip-produced files to skip over<br>
commercials<br>
OR<br>
- Software that can read the comskip generated file(s) and will cut the<br>
source MPEG file.<br>
<br>
After you cut the mpeg file, you can transcode into whatever other<br>
format you (or your playback devices) prefer. I prefer h.264/MKV<br>
containers since they support multiple audio and subtitle tracks and can<br>
correct for FPS issues to sync the audio/video with out lengthy<br>
processes. The only down side is older devices don't support MKV and to<br>
use it with 7MC, you need 3rd party codec paks - I don't "do" 7MC for<br>
playback. XBMC rocks.<br>
<br>
There is an AVI file commercial marking program, but since AVI files<br>
need to be cut on GOP boundaries, I found that a little less than optimal.<br>
<br>
VideoRedoPlus works with comskip's .vprj "cut" files. That software has<br>
comskip-like commercial locating built-in too, but automating it sucks -<br>
AHK can be used. If you care about subtitles, you'll want the more<br>
expensive TV Suite - sadly, it only runs under Windows.<br>
<br>
I'm still looking for a Linux-based, frame accurate, video editor that<br>
works with comskip cut files (.txt, .edl, .vprj, etc.). Since comskip<br>
isn't 100% accurate at locating commercials, manual tweaking of the cut<br>
points is required. It does a good job of getting very close, if not<br>
perfect.<br>
<br>
Ideas?<br>
