macOS 10.15 Catalina
FIXED with Video Improve v2.8.1, Easy Cinemagraph v1.9.1, Video to HTML5 v1.6.1 and everything else in v1.4.0 - if you are affected by this, please make sure to update your software.
With the new security features introduced in macOS 10.15 Catalina, opening any of our apps will show the below warning / request. Feel free to click "Deny" - this will not impact the app's features or capabilities in any way. We're looking for a way to fix this and hope to provide an update soon. Untilt then: sorry for the inconvenience.
Updating through the app itself (using the "Download & Install" button in the "Update available" dialog") has several issues in software versions older than Video Improve v2.6.3, Easy Cineamgraph v1.6.1 and Video to HTML5 v1.3.1
Depending on the version you are trying to update from, you will probably get different errors like the update not downloading at all, downloading but ending up in a corrupt file or getting an error message saying "handshake failure" or similar. Please download the software update through the download page on our website.
Starting with the versions mentioned above, updating should work as expected.
Note: The error does not affect Mac App Store & Steam versions, which are being updated through Apple's and Valve's system.

Exporting videos can be slow and this is a rather complex issue. To get a better understanding, please check this blog post.
"Can I use your software with camera XY?"
For Video Improve & Photo Improve we often have users asking about fisheye removal (or general compatibiliy) with certain cameras which are not on the list of cameras for which we provide lens profiles.
Our software can process files taken with any camera, provided the file format is supported (JPG/PNG for images and pretty much everything - except MPEG2 and RAW formats - for video). The list of cameras we provide refers *only* to the lens correction profiles that are built into the software, not any other features. Those will work with any file / camera.
If you want to undistort pictures taken with a camera not on our list, you have the following two options:
- Use one of the other built-in profiles. You should be able to get good results (for action cameras in particular), though it will take a bit of experimenting until you figure out which profile works best for your camera (we can't offer any help here, sorry).-OR-
- You can create a lens profile for your camera yourself: Go to "Advanced -> Distortion -> Create camera profile..." and follow the instructions.
Video Quality, Bitrate and File Size
When exporting a video, most video editing software requires you to choose the so-called "bitrate" (often along with several other options). As this can be confusing, our products offer a "Quality" setting (1-100) instead:
This "Quality" value translates to bitrate, but it also takes the following into account: the codec (quality 50 means a different bitrate for e.g. WMV or MP4 output), the resolution (twice the pixels means twice the bitrate for the same quality) and the frame rate (twice the fps = twice the bitrate).
The "expected" size you see is a rough estimate (more or less accurate depending on the codec you use). The actual size will only be known after encoding, because the encoders' compression will figure out how far it can compress a file while it is processing. Compression depends mostly on what the video data looks like, i.e. how much detail there is in it (a uniformly blue sky can be compressed very well, but leaves on a tree have a lot of structure and need a lot of data). It may also depend on how much "motion" there is in a video (taking a video of a static scene compresses much better with some codecs, while for others it makes no difference).
By default, when you import a file, some of our products (Video Improve, in particular) will try to use a quality setting that will result in an expected file size similar to the input. This roughly translates to the same bitrate, but note that for different codecs, the same "bitrate" will yield different results. However, it's possible to override this in Video Improve's settings menu -> Default Export Settings -> you can set a default quality value here (e.g. I have mine set to 90). If you want to use the default "file size matching", make sure the "[ ] Quality" setting here is disabled.
In addition to choosing bitrate, the "Quality" setting can also affect some other video encoding options. For MP4 / H.264 in particular, lower quality settings also make the encoder faster (but also more lossy).
Some video codecs (uncompressed AVI in particular) don't have a "Quality" setting. These will output a video at the maximum possible quality, resulting in a very large file.
