The left side of that item was trimmed and then I control-clicked the track mute on the other video tracks to find the next camera shot. That then showed the vision for that camera. To edit the video, I control-clicked the track mute on the camera I wanted to see so only that track was UNmuted. I then muted all but a couple of the more predominant audio tracks temporarily and then proceeded to edit the video. After doing that, the original video tracks have their audio set to ignore (select all video items, control-F2 and select 'ignore audio'). I used markers at the start of each scene.Īfter dropping the video files onto individual tracks, I then duplicated them and glued the audio on the duplicate tracks. There are actually sixteen cameras in total but three of them didn't contain any relevant footage so they weren't used at all. I've only shown ten tracks here because I didn't use all thirteen cameras in this particular part of the edit. The top ten tracks (of the thirteen total cameras used) are the video edit tracks (each camera is on its own track). This screenshot is the project state after the final render (click image for full resolution). Hopefully that will give a better overview than a description alone (something about a picture and a thousand words comes to mind). Here's a screenshot and a little detail about what it contains. The original rate was somewhat lower but I used that to minimise the losses given that there was still two more stages of conversion before the final files were done (conversion to MJPEG during REAPER render, conversion to UT420 lossless compression for importing to VirtualDub for noise reduction and deblocking and final conversion to H264 MP4. The average data rate of the converted files was 5Mbps. It meant that some of the files dropped into REAPER had data rates much higher than necessary but it worked and didn't cause any issues so I didn't bother wasting too much time trying to figure it out. The TRUE framerate was 12.5fps so that is what I set the REAPER project to and is what the final render was. I ended up just converting them at the reported framerate and dropping them into REAPER. I couldn't get ANYTHING to alter those errors (not even MYFFMPEG) without it changing the duration of the files and chopping out much of the footage. It wrongly stamped the framerate of some of the files as 50fps, 200fps and even 250fps. The DVR is, to be perfectly honest, a pain in the backside with its Linux based OS and weird file formats. I had some trouble with framerates and bitrates of the original files. How high was the bitrate for the newly created MP4 files that you had used for editing ? Everything was done from the one project in REAPER. I also used two of the outside camera mics as a spaced pair for stereo audio. There was plenty of panning, level and mute automation in this project as a result. I did a complete audio post production of this one too and panned each camera in stereo and switched to various different audio feeds to match the screen action. There are some things that could be changed to improve that workflow but the fact that I can effectively and reasonably efficiently undertake such a complex edit in AN AUDIO DAW is quite simply, impressive!! If others are interested in my workflow, I'm happy to go into more detail here. REAPER handled it easily though and the rendered file looks good. The video was not high resolution by any stretch (only 352x288 for each camera) but the fact that there was 13 of them in this edit and the files were all streaming from an external USB 3 drive was still a fair test of resources. The camera audio on some of the outside ones needed a lot of cleaning up and I used a combination of REAPER stock plugins and iZotope RXII Advanced for that job. This was a HUGE job and took me two days to edit. Everything sync'd nicely and REAPER remained responsive and snappy even with 13 cameras in the project. I used REAPER for the job and it handled it beautifully. I recently had the job of editing a 13 camera security log (each camera also has its own audio) of a major event where some tenants of a local hostel went on a rampage smashing windows and threatening to kill people with knives!! The cameras are located over three floors and some outside and my job was to produce a final product in one video of the entire event cutting between cameras to show a cohesive overview of the entire event. Just posting a big thumbs up here to the effectiveness of REAPER for its current video editing development.
