Calculate what portion of the ruler will be visible, and only draw that.Then I can edit with those…but that’s a LOT of hard drive space! Would it work just as well to use intermediate MLT’s to reference the original sources, instead of lossless bounces?ĭrawing the ruler, which consists of a number of text and rectangle objects (to make lines to tick marks) was most time consuming I suppose my original project might benefit from an intermediate bounce to a set of lossless files, just with the audio lined up and swapped. That seems to be just as slow as the 8-hour one that I showed at first, although the similarity might be subjective. I’ve also had the same problem in much smaller projects, where I might have 90 minutes of source footage to edit down to about 45 minutes. Once I have a finished product, perhaps starting somewhere around the 3-hour mark or wherever it happens to materialize, I’ll delete everything else, remove the leader, and export. I just wanted to get everything in, the separate audio lined up, and have it all available so I can cut/paste/etc, with it all right there and handy. My expected final length for that project is around 30-60 minutes. This is mainly because your timeline project is nearly 8 hours long. It seems to me that the code is trying to do far more work than is actually required, so is there a setting or technique somewhere to eliminate that work while keeping a GUI-based workflow? The tutorials and FAQ didn’t say anything different from what I’m already doing, or at least not that I noticed. It seems to be better on both ends to be zoomed in all the way while doing it, but still not what I would call “good”. Once it unfreezes, I can…slowly…painfully…put it where I want it with maybe 0.5 fps update rate. Dragging the start of a clip is much worse than the end, with a “Not Responding” hang between the first mouse-drag motion and the clip finally moving, during which I’m just sitting there holding the mouse button down. Much faster to split and lift than to drag the trim bar, but of course I can’t extend that way. Similarly, dragging the start and end points (green and red bars) can take forever. Other times, it finishes immediately, with no apparent connection to the size or complexity of the project. I get it close, then zoom way in for the fine adjustment, and that fine adjustment by one or two frames sometimes takes as long as it did to zoom in. (but not all the time) I’m recording the video and audio separately because my phone mic isn’t very good, so I need to line up the waveforms and then mute the video. Total size of all source files is 37.9GB.Īs noted before, zooming the timeline is slow, and also, moving a clip on the timeline is sometimes slow. I really wish I could make it fixed, but I can’t.Īll of the audio clips are mono wav at 48kHz, some 32-bit integer straight from the recorder and some 32-bit float from Audacity. The second Task Manager window was captured later and pasted in.Īll of the video clips are mp4 from my phone, variable frame rate around 28.5-ish with no setting on the phone to change it. It took about 15 seconds more to finally be done. It may not be perfect, but it gets the job done quickly with quite a bit of customization.All except the second Task Manager window on the right were captured at the same time, about 60 seconds after I moved the zoom control from all the way out to all the way in. Feel free to play around with each of those settings. You probably don’t need to go as extreme as I have for the example above. Change Interpolation to Nearest Neighbor.Click Configure Hardware Encoder and double check that your using the correct GPU or APU.This seems like a very common issue with these open source video editors, but I have found a few settings that may speed it up for you. You may have noticed the editor lagging as you watch the slideshow in the timeline. Find what settings works best for your needs.Select all of the pictures that you want in the slideshow.Import all of your pictures into the playlist panel on the left hand side.This does exactly what I was hoping to achieve with those scripts. In the past I tried to create an ffmpeg script to do this for me, but I was unsuccessful.
