To stabilize your video you can use the ffmpeg command line tool. The easy way: one pass using deshake filter ffmpeg -i shaky-input.mp4 -vf deshake stabilized-output.mp4 The deshake filter has also some optional settings. The better way: two passes using vidstab filters For better results you can try the two-step process using ffmpeg's vidstabdetect and ...

A while back I ran some introductory video editing workshops. I used to tell the participants about a particularly cool effect that I once found in Pinnacle; it was a pinhata that came swinging into the first video along with a stick that hit the second video out of it and it unfolded across the screen. The point of this anecdote is the following: Don't use ...

If you can script yourself, all you need to do is call FFmpeg repeatedly: ffmpeg -ss [start-time] -i input.mp4 -c copy -t [clip-time] output.mp4 Here, start and clip times can be in the form HH:MM:SS.mmmm, or just in seconds. To give you a rough idea how that'd look like in Ruby, see this Gist of mine. It contains a script that takes an edit list, a ...

According to Adobe, it's a bug. Until Adobe fixes this bug with an update, the workaround is to switch off GPU acceleration in Project Settings.

I believe the only answer to that is to take at least a 24hr break. Move onto another project or start something new. The number of times I have come back to something after a decent break and can all of a sudden see what needs to be done is shocking. I don't believe their is a quick fix to this issue.

Curious... recent versions of KDEnlive practically push this option into your face once you add a clip with properties different from the project. If the option got disabled in your setup you can enable it again by going to Settings -> Configure KDEnlive -> Misc (selected by default) -> [ ] check if first added clip matches project profile I am using this ...

This can be accomplished with the mpdecimate filter in the free program ffmpeg: ffmpeg -i "in.mp4" -vf "mpdecimate" "out.mp4"

This should do it: ffmpeg -i input.mp4 \ -filter_complex "[0:v] crop=iw/3:ih:0:0,pad=iw:2*ih [left]; \ [0:v] crop=iw/3:ih:(iw/3)+1:0 [middle]; \ [0:v] crop=iw/3:ih:(2*iw/3)+1:0 [right]; \ [left][middle] overlay=0:main_h/2,pad=iw:(3*ih/2) [out1]; \ [out1][right] overlay=0:(2*main_h/3) [fout] " \ -c:v libx264 -an -map "[fout]" trisected-vertical-overlay....

Here's a way to do it with the blackdetect and trim filters. First, a better way to get the blackdetect output is via ffprobe because it is capable of writing structured data such as XML, JSON or one key=value per line. You do this using metadata injection: ffprobe -f lavfi -i "movie=/path/to/input.mp4,blackdetect[out0]" -show_entries tags=lavfi....

Is Adobe Premiere Elements good enough for video editing? In general, yes. It is a watered down Version of Premiere Pro for people that would be overwhelmed by a full-featured professional editing tool and just want to cut their video easily and quickly. This means that a lot of the features of Premiere Pro will only be available in a simplified variation,...

If you have a frame where the person does not exist, you can use a tool called a difference matte. (You'll need to scroll down to the section titled "Difference Matte Effect" for a description.) It will find a difference between the frame without the person, and the frames with a person and remove areas that are the same, leaving only the difference (in this ...

While its technically possible to have a program detect specific faces and apply a blur on that face. That would require a lot of programming work on your side, there is no free tool or low cost tool that does this automatically for you. This is possible with OpenCV but I highly doubt that this is a viable solution for you in any way, it's a quite ...

After Effects could certainly do what you want, as could Apple Motion (only for Macs though). If you're on a budget you might want to look at something lower cost - or free: Natron is an open source free compositor, that will be able to do that effect Blender - as well as being a 3D animation package it has a compositor too compositing is the technique of ...

I've not used it, but Microsoft makes Microsoft Movie Maker. It might meet your needs. There are also some open source video editors you might have luck with: ShotCut - http://www.shotcut.org - kind of new, might be buggy Blender - http://www.blender.org - it's a 3D modelling app with video editing capabilities Lightworks - http://www.lwks.com - there's ...

Use ffmpeg (download a static build for your operating system) and its delogo filter, which will try to cover up a logo or watermark by interpolating neighboring pixels. ffmpeg -i input.mp4 -vf "delogo=x=100:y=100:w=150:h=20" output.mp4 Here, x and y specify the top left coordinates of the “masking” rectangle, and w/h specify its size. You can add the show=...

There are methods to generate frames in between frames, mostly giving you mixed results. For one, the plugin "twixtor" (~330$) actually does a somewhat decent job at assuming missing frames, so much so, that a 30fps video can be played back at half the speed, making it look like 60fps slow-mo. On the other hand side, you can sample the frames directly in ...

While the cat/copy option mentioned generally works, I've found that it can cause problems with some media players, due to timecode issues. I would prefer to use ffmpeg's concat protocol to achieve the same effect (but more reliably in my experience): ffmpeg -i "concat:in1.m2ts|in2.m2ts|in3.m2ts|in4.m2ts" -c copy output.m2ts

When you shoot from further away you use a "longer" lens, in other words a lens with a longer focal length. This has a few effects, that you'll have to fake to make it look real. First, the perspective tends to get flattened with long lenses. You've probably seen this in the classic cinema trope of a long shot of a crowd walking along a footpath, where ...

The biggest problem you are facing is that a DSLR typically records to the H.264 codec. That codec tries to minimize the file size and the only way to achieve that is to throw out negligible information. Sadly human eyes are not sensitive to black parts of video, so dark areas are highly compressed. That means you will have a really hard time brightening ...

Have a look into the new Blackmagic Davinci Resolve, which includes an NLE and color correction tool. it is free and can output a maximum resolution of 3840x2160.

Using crop and vstack: ffmpeg -i input -filter_complex \ "[0:v]crop=iw/3:ih:0:0[left]; \ [0:v]crop=iw/3[center]; \ [0:v]crop=iw/3:ih:ow*2:0[right]; \ [left][center][right]vstack=inputs=3[v]" \ -map "[v]" -map 0:a -c:a copy output vstack is faster than pad + overlay. If your ffmpeg is too old for the vstack filter then just download a recent build.

There is a big difference between saving your project, then returning to the project to do some additional changes, such as brightness adjustments, then exporting a media file, and exporting a media file from your project, importing the result into a new project, doing some additional changes, such as brightness adjustments, then exporting the result of ...

Blender has motion tracking, which can in turn be used to stabilize video. Here is a YouTube tutorial showing how to load video footage into Blender's movie clip editor, setting a tracking point, solving the tracking equation, and then discusses considerations about how to balance the various factors between too much and too little stabilization. The video ...

Final Cut Pro X has a plugin called Pro Removal that can remove moving things from the scene on fixed camera shots. Also there is a tutorial for After Effects that shows how remove objects from scene using the tracker. Also you can clean frame by frame using Photoshop or similar if you have a good amount of time to spend or a crew to help you in the task.

It depends entirely on the type of rendering you are doing and the specs of your computer. Bottle necks can occur in many different parts of the rendering pipeline. Generally speaking, rendering is very GPU or CPU intensive, depending on if the render engine is CUDA (or similar) enabled. If the renderer is able to utilize a GPU, then GPUs and/or dedicated ...

This question gets asked quite frequently, and normally the answer is to pick one from this list. But since you very clearly defined what you are looking for in the editing software, I think I can give you a better recommendation. Premiere Elements Personally, I use Creative Cloud software, which means Premiere Pro for video editing and After Effects for ...

With a 99% chance After Effects was used here. As long as you plan on doing a commercial video I would avoid home video production programs like iMovie at all costs. Specially because iMovie is made for cutting video and not making animations. That's like making a commercial in Windows Movie Maker. There are many many talented freelancing After Effects ...
