.cap Viewer
Dimple Belousson
I have an issue where I am creating .cap files with aircrack-ng and am saving them to the desktop, but I can't see them. When I use the ls command in the terminal they show up, but just not on the graphical desktop view. I want to be able to see them on the desktop and not just through the terminal. Any help would be appreciated, thanks!
EDIT: Turns out I am not saving them to the desktop, but rather the /home/user/ directory. The hidden files show up when I press CTR + H, but they don't show up in the terminal; the only file showing up in the terminal when I use the ls command is the desktop (sorry for the topic edit). How can I get the hidden files to show up in the terminal as well?
A SubRip (.SRT) file is by far the most common sidecar file for prerecorded web videos, and is preferred by many video hosting platforms (including YouTube) thanks to its adaptability. It can be used for both closed caption and subtitle workflows.
Elegant in its simplicity, the .SRT file can be opened up and read by a human. It is a basic text file that contains sequential numbering for each caption, its in-time and out-time, and the text content of the caption itself. When uploaded with its corresponding video, web players use the timing information to sync the captions so they display properly for end users. Some video players can decode formatting information in .SRTs (italics, positioning, etc.), but not most.
On the surface, .VTTs look almost identical to the .SRTs; when you look closer, they are much more feature-rich, with more universal support of stylistic elements like italics and movement of text. Some players can use .VTTs, while others like Vimeo prefer them.
WebVTT (.vtt) is similar to the SRT format except that it accommodates text formatting, positioning, and rendering options (pop-up, roll-on, paint-on, etc.). It has quickly gained popularity because it is the caption format of choice for HTML5 text track rendering.
WebVTT caption files are compatible with videos on cloud-based, HTML5 media players and video management systems like:
Television content providers like to use SMPTE-TT because it is compliant with FCC closed caption regulations for broadcasters, unlike other formats like DFXP. Another important difference of SMPTE-TT captions is that they reference video frames instead of video time. SMPTE-TT files end is extension .xml.
It was developed by Cheetah International to accommodate characters in many languages for international use. Cheetah files have the file extension .asc or .cap. This format is used in professional video editing systems.
Closed captions are a textual representation of the audio within a media file. They make video accessible to deaf and hard of hearing by providing a time-to-text track as a supplement to, or as a substitute for, the audio.
While the text within a closed caption file is comprised predominantly of speech, captions also include non-speech elements like speaker IDs and sound effects that are critical to understanding the plot of the video.
Unlike captions, subtitles do not include the non-speech elements of the audio (like sounds or speaker identifications). Subtitles are also not considered an appropriate accommodation for deaf and hard of hearing viewers.
The easiest way to create open captions is to hire a professional captioning company that offers open caption encoding. Open caption encoding can be tricky to do yourself. It can be time-consuming and often requires expensive video software.
Closed caption quality matters because closed captions are meant to be an equivalent alternative to video for individuals with hearing loss. When closed captions are inaccurate, they are inaccessible.
Studies have shown that even a 95% accuracy rate is sometimes insufficient to accurately convey complex material. For a typical sentence length of 8 words, a 95% word accuracy rate means there will be an error, on average, every 2.5 sentences.
Knowing how a captioning vendor measures its accuracy rate is important. For example, with some closed captioning vendors, punctuation errors are subjective; even though an em dash, period, or comma could make all the difference to the meaning of a sentence.
With accuracy, the FCC states that closed captions must match the spoken words in the audio to the fullest extent. This includes preserving any slang or accents in the content and adding non-speech elements. For live captioning, some leniency does apply.
WCAG 2.0 has three levels of compliance: Level A, AA, and AAA. Level A is the easiest to complete, while level AAA is the hardest. Most web accessibility laws require compliance with Level A and/or AA.
Lastly, an integration or an API workflow is a way to automate the process of adding closed captions. Essentially, you are creating a link between your captioning vendor and video player to allow your captioning vendor to automatically post your captions back to the original video file.
Did you know more than 500 million hours of videos are watched on YouTube each day? YouTube is pretty much the king of video content on the internet. In fact, every 60 seconds, 72 hours of video are uploaded to the platform.
Always be careful with YouTube closed captioning and be sure to edit the final closed caption file before publishing. If you upload poor-quality captions, Google will flag your content as spam and penalize you in search results.
Adding technology into the mixture can cut your time by more than half. On average a trained transcriptionist can take four to five hours to transcribe one hour of audio or video content from scratch. For an untrained novice, this can take much longer.
41% of videos are incomprehensible without sound or closed captions. This means that if you are not closed captioning your videos, viewers are most likely scrolling past your videos without playing them.
There are four important steps in a closed captioning workflow: transcribing the video, synchronizing the text, controlling quality, and managing the overall process. All these steps impact the final cost of your closed captions.
The first step in closed captioning is to transcribe the video. This is often the most time-consuming part. A trained transcriptionist will take four to five hours to transcribe one hour of normal audio or video content.
As an untrained transcriptionist, a student or intern can take five hours or more to transcribe a one hour file. If this student is paid $15 per hour, this means it will cost $75 to transcribe a one-hour-long file.
A good quality check should take longer than the duration of the actual file. So for an hour and a half of quality check the total in-house cost of closed captioning rises to $112.50 per hour of content.
While in many cases the price you pay is low, the consequences of using a low-quality file are pricey. For instance, you have to QA the file yourself, which takes up time away from other tasks. There are also additional costs if you resubmit a file, or order a certain closed caption format.
Different vendors have different processes for closed captioning. The process will directly correlate to the price. Although it can be enticing to go for the cheaper option, the quality of the closed captions you get back might not be worth it.
A good closed captioning vendor will have a clear workflow. They will offer different methods to upload videos, they will let you know when closed captions are ready, and they will store your closed caption files for you.
Instead of not closed captioning at all, try prioritizing your popular videos for closed captioning. Caption videos that have the most views, shares, or engagement; caption videos that are in more prominent places, like on your homepage; and caption videos requested by viewers.
Quicker turnaround options can make closed captioning costs add up. Sometimes, you may need a closed caption file within 2-hours or by the next day, but if you can avoid having a rushed turnaround time, you can actually save a ton of money.
Getting buy-in for closed captioning takes work. In a study we conducted on the state of captioning, we uncovered that the true decision-makers for funding closed captioning are often unaware they are required to caption.
Exemptions are applied to organizations where the implementation of these requirements would cause undue hardship. However, organizations are still required to provide an alternative method for communicating the information to individuals with disabilities.
Local government, state government, private colleges, and public colleges note in Title II of the ADA. Title II of the ADA has also been applied to private entities. Under the Title, employee training videos must also comply with the ADA.
Streaming sites like Netflix, Hulu, and Amazon, must caption all content that was previously aired on television. Note: Under the ADA, streaming sites must also caption original content, even if it never appeared on television.
In addition, these institutions must be mindful of other accessibility laws that apply to them. Private and public colleges, state governments, municipalities, and K-12 must also adhere to the Rehabilitation Act and the ADA.
Video content is everything right now, which is why making it accessible should be your top priority. Adding closed captions not only provides greater access to people who are deaf and hard-of-hearing, but it also creates a better user experience for all viewers.
I have some files I used to use on a windows based pc and they are files with a .cap extension. They are schematics for projects I like to work on but cant seem to open them and cant find anything in the app store for .cap files. any suggestions or apps you know of to work with this type of file?
