Based on Studio2021 v3.6.7.
Now lets have a short look at Studio2021's settings. Or better said Preferences, because there are all the detailed option located by which Studio2021's performance can be tweaked and the appearance can be influenced.
You reach the dialog via the top menu bar.
First in the Settings you find the option to enable/disable a status bar which will show you a short information about what Studio2021 does. For example saving a Project file.
Next you can change the Language Studio2021 uses in its GUI.
The Log Directory is of interest in case you have a problem and mailed Insta360 support about it. They might ask you for some logfile of Studio2021 which can be found by following that option.
Yes, we jumped over "Preferences" but because it hols a bunch of additional options it looks reasonable to cover that in the next chapters.
The "Preferences" are organised in three main sections which then also split in sub-sections.
A (video) codec refers to a pair of algorithms for encoding and decoding digital videos. This gives your videos an interchange able format and size. As those do calculations those can be done purely on the CPU or on a hardware which supports the related codecs. Most Graphics Processing Units (GPU) have the encoder/decoder stored in their hardware and using such a supporting GPU speeds up the processing of a video immensely.
- Exporter Codec
- Use Hardware Decoder
- Use Hardware Encoder
- Enable CUDA acceleration on Windows (if the graphics card supports)
- Player Codec
- Use Hardware Decoder
During export, Exporter Codecs are used. Don't be confused by the "Hardware Decoder" option, even though exporting means encoding. But the h.264/h.265 stored in the insv must be decoded before your edits can be encoded into a new file, which is then saved as mp4 (h.264/h.265) or ProRes, depending on your choice in the export dialogue.
The "Hardware Encoder" covers exactly that last step. To use the hardware based GPU support for encoding videos to h.264/h.265.
NVIDIA graphics cards offer an additional option of calculation support. CUDA, which initially stands for Compute Unified Device Architecture, is a parallel computing platform and programming model developed by NVIDIA. By it program code can be "outsourced" to the GPU to speed up calculations.
All three sub-options cover the same purpose, to speed up the encoding/decoding of a video. At first glace it seems as too much good, but not all GPUs support hardware based encoding/decoding for all codecs or mainly h.264/h.265. Some support hardware based decoding of h.265 but not the encoding, which then has to be done on a pure software layer which normally would run totally on the CPU. But if the GPU also supports CUDA there is a chance that parts of those calculations are directed from the CPU to the GPU.
And AMD GPUs do not support CUDA and because of that the CUDA option is of no use with AMD GPUs. They support OpenGL. Which also is a software layer to speed up calculations but needs different methods to be utilized.
The "Player Codec" part is simple. Just for playback, for example in the preview area, a video only has to be decoded. And all current GPUs should support hardware based decoding of h.264/h.265.
This section deals with settings to enhance the image quality and appearance, while Codecs define the "framing".
Image Processing Acceleration
Just as the hardware-based encoder/decoder is responsible for the file format, this option targets the quality of the content in detail. You can leave the choice to Studio2021 if it uses GPU or CPU or lock it on the CPU. Like said, this option is only considered if you've selected to enhance the image / video either with ColorPlus and/or to remove Grain.
This is used to make lines look good, especially if they are not totally horizontal or vertical. In that case, because lines in a digital image are based on pixels, they build steps at their edges. Antialiasing is used to smooth those steps and make them look like natural lines again. Multisampling Anti-Aliasing (MSAA) is the most common technique to do that. Normally it can be used in different grades given as 2x MSAA , 4x MSAA or up to 8x MSAA. But the higher grades have significant impact on the systems overall performance. 8x MSAA can allocate up to 20% of a GPUs performance.
Under this section you can influence if Studio2021 uses more parallel threads for starting exports with "Max Task Thread". The number reflects the parallel started exports. Raising it depends on the computing power of your system and its I/O capacity. Remember, videos do not only need to be decoded/encoded but they also need to be saved to disc again.
It's a good idea to separate the source from the target, meaning have your source video files on one physical drive and the export target on another physical drive. On slower system (CPU/GPU) systems the improvement is relative, nearly not noticeable, but on more powerful systems where you raise the level of parallelism which also hits file handling, you better utilize the I/O channels. Even on PCIe NVMe SSD drives. If you use a cluster storage, MediaHub like or RAID storage system that does not bother you. Nevertheless that kind of structure ease organizing tasks. ;)
The last main section in the Preferences covers automatically functions of Studio2021.
The file path displayed here shows you where Studio2021 saves its project files. Project files are named with the file extension "insprj". In this files Studio2021 saves all edits you do to the source files including information about the AutoFrame clips. You can find more about project files here.
Play sound when export task finished
That is pretty self explaining, isn't it? You enable/disable the "bing" sound played after an export was finally saved to disc. Some like it, some don't need it. It's up to your choice.
Send user data to help us improve user experience
With that you control if Studio2021 is allowed to send data back to Insta360 on automatic basis. This also included crash data, but mostly - as far as I know - statistical data.
This enables/disables if Studio2021 provides thumbnails of images and videos on its different panes. This covers the content list pane, in list & thumbnail view mode. The parts preview row in the preview pane in case of an Interval Shot, HDR image, or AI "AutoFrame" results. This does not influence the with Studio2021 installable file explorer thumbnail plugin.
Accessory Auto Detection
If enabled this allows Studio2021 to decide if and what kind of accessory you used on your camera. It then detects for example Lens Guards and different official cases.
