How do I read the resolution reduction variable? ( I assume its the scale variable).How many of the variables used change based on the input video or do they all change the way the output video is done?.Whats the difference between v1 and v2? a) Do I need v2 or is it just nice extra?.ġ200 video bit rate, reduce resolution, and output wmv1 : mencoder -vf scale=320:-10 inputvideo.m2t -o output.avi -of avi -ofps 15 -ovc lavc -oac lavc -lavcopts vcodec=wmv1:vbitrate=1200:acodec=wmav1:abitrate=128Ģ30 video bit rate, reduce resolution, and output wmv1 mencoder -vf scale=320:-10 inputvideo.m2t -o output.avi -of avi -ofps 15 -ovc lavc -oac lavc -lavcopts vcodec=wmv1:vbitrate=230:acodec=wmav1:abitrate=64ġ200 video bit rate, reduce resolution and output wmav2 mencoder -vf scale=320:-10 inputvideo.m2t -o output.avi -of avi -ofps 15 -ovc lavc -oac lavc -lavcopts vcodec=wmv2:vbitrate=1200:acodec=wmav2:abitrate=128Ģ30 video bit rate, reduce resolution, and output wmav2 mencoder -vf scale=320:-10 inputvideo.m2t -o output.avi -of avi -ofps 15 -ovc lavc -oac lavc -lavcopts vcodec=wmv2:vbitrate=230:acodec=wmav2:abitrate=128

Typically she boots to openSUSE to play videos (where I have the codecs setup) but on occasion she has asked that I convert a video for her so that her winXP partition on her PC will play it. My wife’s winXP PC boot partition is pathetic when it comes to codecs, and one of the few video formats it can play is wmv.

Update II: included results of merge with Avidemux.Other than playing on ZEN, what other benifit is there to wmv? Update I: included results of merge with cat and mencoder. Comments from experienced RecordMyDesktop users are also welcome.

My question comes down to: how to perform these three apparently simple tasks with videos produced with RecordMyDesktop? I would appreciate suggestions either for a completely new processing pipeline or to changes in one of the steps. The resulting videos yield sound and image out of sync when opening a merged file with a player such as Totem, the length is about the double of what is reported by Avidemux.Īt this stage I strongly suspect something is going wrong upstream of the merging step, perhaps with the cropping (and thus the detailed story). Kino - also produces a merged file without issuing errors but completely ravishes the image, it constantly flickers and jumps up and down, making it impossible to understand.Ĭat + mencoder - the end result has similar problems as with avimerge.Īvidemux - eventually found out it is also able to merge files, although the process is not obvious. There are moments where the sound played is from the parts cropped out in the previous step. In total the cropped avi videos add up to little over 200 Mb.Īvimerge - produces a merged file without issuing warning or error messages but the image and sound are out of sync. OpenShot - filled up 4 Gb of RAM and went on to fill 4 Gb of swap, at which point the system became unresponsive, forcing a reboot. So far I have tried this task with five different tools, all of which failed: Totem is not able to play one of them, issuing an exception OpenShot also issues a warning when opening some of these videos cropped with Avidemux. I had no errors performing this task with Avidemux but the resulting videos started to yield problems. Others such as Lives also advertise this functionality but are not able to perform it. With avconv there is a visible loss of image quality and a good deal of noise is added to the audio, but none of it is catastrophic.įor this task the only tool I am aware of that allows cropping at the frame level is Avidemux. Previously I tried with ffmpeg, Avidemux, Lives and others, but all of them fail with errors or crash on Ubuntu 14.04.

Many of these threads seem to be outdated but I eventually succeeded using avconv, e.g.:Īvconv -i 'input.ogv' -vcodec mjpeg -acodec mp2 -qscale 10 'output.avi' There are various threads here about this subject, pointing to multiple tools. Below I detail the steps I have taken so far and the problems I found. Sounds simple, but I have lived a whole saga the past few weeks trying to do it without success. Merge the various cropped videos into a single file. The task pipeline looks like the following:Ĭonvert the files from ogv to avi (or another workable format).Ĭrop unwanted sections from the videos (such as the interaction with RecordMyDesktop itself). I have recorded a few short videos (between 30 seconds and 4 minutes) with RecordMyDesktop that I now need to merge into a single video.
