Technical Requirements
The following technical requirements apply to all video submissions to BGTV.

Video & Audio Format
Resolution must be at precisely 1080p (1920 x 1080) All videos must be encoded as an MP4 using the H.264 codec. Videos must be in a 16:9 aspect ratio.

File Size
For Video Figures: 100 MB. Paper submissions are maximum 120MB in total: paper + video.
For Video Previews: up to 20MB
For Video Showcase submissions: up to 100MB
Handbrake provides good compression results and is available for OSX, Windows and Ubuntu.

Encoding to MPEG-4/H.264 (.mp4)
The Video Previews require MPEG-4 encoding using the H.264 codec (file format .mp4). Most video editing software (such as iMovie, Adobe Premiere, Camtasia, and Final Cut Pro) provides an exporting option to MPEG-4/H.264. There are also a number of free encoding solutions you can use:

X264 Encoding
x264 can encode any video into H.264.
For Windows users, Freemake Video Converter and Handbrake both provide good results.
For OSX users, we recommend Handbrake and other free converters available through the Apple App Store (e.g. Miro Video Converter). For Linux users, FFmpeg is a well-known transcoding solution.

Important
Encode your video using square pixel for the pixel aspect ratio to avoid your movie looking stretched when projected. Note: We do not endorse or are responsible for the use of any of the software mentioned in this guide.

If you compress your video with unusual software or codecs you risk the possibility that reviewers will not be able to watch your video, and it may need to be re-encoded for the ACM Digital Library. CHI does not accept software applications or digital video clips requiring a specific computing platform or additional software to play. Before submitting, we also invite you to check the compliance of your file using the CHI Video Checker. You can also upload your video to Youtube (private) a and check that it play correctly.

General Guidelines
Opening Title:
You must include the Title, Authors of the work and affiliations at the beginning of the video, either as a title shot or as an overlay text. Make sure that you leave the title for long enough of a duration to be read (up to 10 seconds for Video Figures, and up to 4 seconds for Video Previews).

Captions & Subtitles
All spoken dialog must be closed captioned (subtitled) to improve accessibility. You should include subtitles or captions to your video to guarantee that it can be consumed in places with ambient noise, where sound is unacceptable, and by hearing-impaired individuals.

Closed-captioning file Format
A closed-captioning file, in .srt or .sbv format should be submitted along the video. There are several free, easy ways to caption your videos. We recommend uploading your video to YouTube and use the provided captioning tools; You can keep the video private or unlisted and delete it immediately after.
You have the choice to manually create all captions or manually correct them. Afterwards, you can download the .sbv file. A step-by-step tutorial is available here.

The following examples demonstrate good practices for captions and subtitles: bottom banner, top banner and full part of the visual support. Important note: Your captions do not necessarily have to stick to the voice over. Importantly, your video must be understandable without the sound. Here is an excellent example of a video preview that is equally understandable with or without the sound, while the captions are not subtitles.

Meta Data
Please remember to review the meta-data properties of your digital file.
For submission to an anonymized venue, all meta-data that could identify the authors should be removed. For non-anonymized venues or camera-ready versions, Please remember to review the meta-data properties of your digital file and insert appropriate identifying comments at the submission time: Author, Title, and Copyright information.

Camera Ready Version
The camera-ready version of your video submission should contain a title slide with the title, authors, and affiliations. Titles and credits should last no more than 10 seconds (and no more than 3-4 seconds for Video Previews).

Third-party material and Copyright
Authors retain copyright to videos, but BGTV requires that you sign an agreement allowing BGTV to utilise the material.
It is very important that you have the rights to use all the material/content that is contained in your submission, including music, video, images, etc. Attaining permissions to use video, audio, or pictures of identifiable people or proprietary content rests with the author/producer, not on BGTV.

You are encouraged to use Creative Commons content, for example music available at ccMixter or Newgrounds. If you need to use copyrighted protected work, you are required to review and comply to BGVT's Copyright and Permission Policy and BGTV's Requirements about 3rd party material In addition,
