Epic OpenShot 2.0 Update! (Part 3 of 3)


Welcome to third and final update of the Epic OpenShot 2.0 Update! I've already received some great feedback on the previous two updates, so thank you for that. This update will not be as technical as the previous, so hopefully everyone who was a little lost will enjoy this one more.

Open-Source Challenges

As everyone reading this knows, OpenShot 2.0 is an open-source application. Kickstarter has been a challenging balancing act. Certain backer levels on Kickstarter are promised early access to various things, such as alpha, beta, and final releases. But how can an application be built and shared freely, while also restricting parts of it to a small group of people? It is a challenge, and here is my plan to solve it.

The alpha, beta, and final installers (i.e. easy ways of installing and configuring the binary application files), will be released first to the backers on Kickstarter (as promised). After all, without their support OpenShot 2.0 might never have happened.

However, the source code to OpenShot 2.0 should be released to the broader open-source developer community prior to me building the installers. I need the community to get involved with testing, bug fixes, translations, documentation, and even packaging. This will result in a much happier community, and a much better product for the backers on Kickstarter.

So, my current plan is to first release the source code to the OpenShot Library, and then soon after that, the PyQt source code to OpenShot 2.0. For the average person, compiling OpenShot 2.0 themselves would not be advised, and they should wait for the alpha, beta, and final releases (with installers). I hope that all makes sense, and if not, please feel free to share your questions or comments with me.

Web-Based Video File Testing

One of the most important (and challenging) tasks for a video editor is to offer broad support for your favorite video formats. This is currently accomplished by utilizing the FFmpeg and/or libAV projects. So, while I don't have direct control over these formats/codecs, it is my job to integrate them as best as possible.

Later this month (or possibily early February), I will be launching a web page which will let you share sample video and audio files with me (as long as they are less than 50 Mb). These sample files will feed into an automated testing suite that I have developed, and will be inspected, decoded, thumbnailed, audio waveforms generated, and transcoded. The results will be posted on the website... although I will probably not share the actual video file or thumbnails (due to copyright issues, inappropriate content, etc...). My ultimate goal is to develop a huge cross-section of video files with different formats and codecs, which can be used now and in the future to regression test updates to libopenshot. In other words, this will help compile a list of compatible video and audio files, as well as identify issues with certain file types. It is also another great way for people to contribute to OpenShot.

Common Profiles

What is a profile you ask? Well simply put, a profile is a collection of video settings, such as height, width, frame rate, display ratio, pixel ratio, etc... OpenShot has a large list of "profiles", but I am very interested in the most common profiles used by normal users. So, I will also soon be releasing a simple web-based form, which will allow users to submit their favorite and most common profiles they use when editing videos. I will also display this information on the website (in total), for others to view. This data, along with the previous data-set of supported video and audio files, will help me ensure I support the most popular formats and profiles, and thus, I satisfy the largest group of users.

Southern California Linux Expo (SCALE 12x)

On February 21 to 23, I will be representing OpenShot at SCALE 12x, one of the largest community run events focused on Linux and free software in the United States. Although this might take a few days away from programming, it is an important event for OpenShot and a chance for me to meet many users face-to-face, listen to feedback, and meet with other OpenShot developers. I will be demonstrating OpenShot 2.0 LIVE at the show, and hopefully by this time, many of you will also be playing with an alpha release at home. =) I'm also considering having a LIVE stream of the event, but I'm not sure I'll have enough bandwidth for that yet. So, if you are near Los Angeles, CA towards the end of February, please stop by and hang out with us a bit.

Thanks for your Support

One again, thank you EVERYONE for your support! OpenShot 2.0 is moving along as quickly as I can build it. I will be posting a new update at the beginning of each month, and will be releasing an alpha as soon as everything is stable. On a final note... I'm still fighting a C++ heap corruption issue on Windows, and if any expert C++/MinGW developer wants to jump in an offer me a hand and be a hero, please send me an email to!

      i backed because it is an open-source solution in the first place.. so the early access does not really matter in this case.

      I don't care for early alphas either. As long as this will be a good, stable open source software that can be installed with aptitude, I'm satisfied.

      I backed this to see that a stable version of OpenShot makes it to Linux. All the rest is gravy. Early access doesn't matter that much to me. Don't get me wrong, I'm looking forward to it, but as long as it gets here I'll be happy.

      Thank you Jonathan for the Fast and Exhaustive feedback.

      Your plan for release sounds fine to me. I backed this hoping for a successful Open source video editing platform on Windows. The more folks contributing the better.

      Keep up the good work.

      Hi Carlo, thanks for the question! I chose MinGW over MSVC for a few reasons (and who knows, maybe I'll be forced to use MSVC before this is all over). First, many of the dependency libraries I need are only compiled with MinGW. So, rather than move all these libraries over to MSVC, I thought it made since to keep the stack in MinGW. Also, I liked the idea of using the GCC on all platforms, for consistency sake. Finally, I liked the fact it did not require any Microsoft tools, which can be problematic for certain open-source developers and certain parts of the world. Maybe these reasons are silly, and MSVC would make all my heap corruption issues go away.. so who knows. I'll have to see what happens. =)

      Hi Jonathan,
      just a question, as both Windows and Linux developer (mainly Windows) I would like to ask a question.
      Why did you chose to use MinGW instead of MSVC, like other opensource projects like Firefox?
      As personal experience MinGW is good but a little bit buggy.

      thank you in advance
