--- title: Audio, Videos, Images slug: hardware/audio-videos-images docTags: createdAt: 2025-03-11T06:58:50.142Z --- # Are multiple audio tracks supported? Yes. All audio tracks must have the same sampling rate and bit depth if you plan to output multiple audio tracks simultaneously from either audio or video files. You can mix multiple audio files together (for example, by adding multiple zones in BrightSign Author) and send them to the same output, or output two audio streams simultaneously: one via the HDMI, and a second via the 3.5mm audio or SPDIF using an .mp3 or .wav file. The AU335 supports up to three zones for audio. For example, you can create two analog-output zones, but one is stereo right and the other is stereo left. Or, you can create two zones where one is analog and one is HDMI. See [this page](docId\:Hs4EUH9JcuiJcBafGShef) to make sure your audio format is supported. # Can players output component & composite video? Series 2, 3, 4 and 5 BrightSign players do not support component or composite video without an external converter. HD810 and HD1010 players come installed with YPbPr component connectors. Using a third-party VGA converter, you can also play component and composite video on other models. There are many third-party VGA breakout cables; however, some VGA breakout cables will not work with the VGA port on a BrightSign player. You will need to ensure that the VGA converter you purchase has the same pin layout as outlined below: | | **Pin 1** | **Pin 2** | **Pin 3** | | ------------------- | --------- | --------- | --------- | | **Component RGB** | Red | Green | Blue | | **Component YPbPr** | Pr | Y | Pb | | **S-Video** | C | Y | - | | **CVBS** | - | - | CVBS | In BrightSign Author or BrightAuthor Classic, configure the output for component/composite as follows: **Component**:  Select Component from the **Connector type** drop down menu. In the **Screen resolution** drop down menu, you may choose any 1080,  720, or 480 option, as well as the NTSC-COMPONENT and PAL-COMPONENT options. **S-Video or CVBS**: Select HDMI from the **Connector type** drop down menu. In the **Screen resolution** drop down menu, you may choose the following options: - PAL-N - PAL-M - PAL-I - PAL-BG - NTSC-M-JPN - NTSC- # Which media files are compatible with my player? You can use MediaInfo to check if your files are compatible with a player. To do this: 1. Download [http://mediaarea.net/en/MediaInfo](http://mediaarea.net/en/MediaInfo) and install it on your system 2. Launch MediaInfo and go to **View > Select Text**. 3. Go to **File > Open > File** 4. Browse to your file and click **Open** :::ExpandableHeading **Output** Your output should look something like this: ```text General ID : 1 (0x1) Complete name : F:\FromVOBtotsfromffmpeg5.ts Format : MPEG-TS File size : 90.0 MiB Duration : 4mn 9s Overall bit rate mode : Variable Overall bit rate : 3 022 Kbps Video ID : 256 (0x100) Menu ID : 1 (0x1) Format : AVC Format/Info : Advanced Video Codec Format profile : High@L3.2 Format settings, CABAC : Yes Format settings, ReFrames : 4 frames Codec ID : 27 Duration : 4mn 9s Bit rate : 2 485 Kbps Width : 720 pixels Height : 576 pixels Display aspect ratio : 16:9 Frame rate mode : Variable Standard : PAL Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Stream size : 74.0 MiB (82%) Writing library : x264 core 142 r2431 ac76440 Encoding settings : cabac=1 / ref=3 / deblock=1:0:0 / analyse=0x3:0x113 / me=hex / subme=7 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=1 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=12 / lookahead_threads=2 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=1 / b_bias=0 / direct=1 / weightb=1 / open_gop=0 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=40 / rc=crf / mbtree=1 / crf=19.0 / qcomp=0.60 / qpmin=0 / qpmax=69 / qpstep=4 / vbv_maxrate=20000 / vbv_bufsize=25000 / crf_max=0.0 / nal_hrd=none / filler=0 / ip_ratio=1.40 / aq=1:1.00 Audio ID : 257 (0x101) Menu ID : 1 (0x1) Format : AC-3 Format/Info : Audio Coding 3 Mode extension : CM (complete main) Format settings, Endianness : Big Codec ID : 129 Duration : 4mn 9s Bit rate mode : Constant Bit rate : 384 Kbps Channel(s) : 6 channels Channel positions : Front: L C R, Side: L R, LFE Sampling rate : 48.0 KHz Bit depth : 16 bits Compression mode : Lossy Stream size : 11.4 MiB (13%) Menu ID : 4096 (0x1000) Menu ID : 1 (0x1) Duration : 4mn 9s List : 256 (0x100) (AVC) / 257 (0x101) (AC-3) Service name : Service01 Service provider : FFmpeg Service type : digital television ``` ::: BrightSign Support will ask you to send the above information (in the above Text View format) if you contact us and we suspect that your audio/video files are impacting your player's behavior. When using H264 encoded video please make sure that you check the Format profile (Format profile: High\@L3.2 in the above example) and that it is within the specs described on [this page](docId\:knsFFwMTD4NswXm4BUP0I). # Which players can be synchronized? You can synchronize models from the same model family: For example, the HD1020 can be synced with the HD220, or the 4K242 with the 4K1142. However, you cannot synchronize models from different model families: For example, the XD230 cannot be synced with the XD232 or HD220. Players must be synchronized over an Ethernet connection (not WiFI). You can synchronize two units by connecting them directly to each other using a standard Ethernet cable; for any larger deployments, you will need LAN infrastructure. See [this page](docId\:STOuPgRPoR4d3PdB1rHpE) for more information on synchronization. # Can I reduce streaming playback latency? The *low\_latency* parameter for RTSP streams, on BrightSignOS version 6.2 and above, lets you achieve a much lower streaming latency than normal, but at reduced maximum bitrates (for example, *rtsp\://example/media.amp?low\_latency*). This option is ideal for IP camera streams on the local network. # Do players support Genlock? Genlock (frame-accurate VSync) is available with BrightSignOS version 7.0 and is automatically integrated in all BrightWall™ and Enhanced Synchronization presentations as of BrightAuthor Classic version 4.7.1.x or later. The current version of BrightSign Author doesn't support BrightWall™, but does support Enhanced Synchronization. BrightAuthor Classic versions 3.8.0.x or later support BrightWall™. BrightSign Author and BrightAuthor Classic can be installed and used on the same computer.  Note that synchronization is not supported over wireless connections. # Do players support USB audio? You must use a plugin or script to play USB audio with BrightSign players. Digital audio output is supported over HDMI and SPDIF. # Do players support closed captioning / subtitles? Yes, you can use any of the following methods: - If your video content has caption information encoded in it, you can display that caption using [HTML](docId\:e6uJleH69Q0JmMv8kyTrp). No extra plugin or scripting is required. Non-HTML video players support this also, but a plugin is required to turn on the feature. Once it is turned on, you can display the caption information that is embedded in the video. - BrightSign players can display closed-captioning streams from video through  [HTML video elements](docId\:e6uJleH69Q0JmMv8kyTrp), as well as the [roVideoPlayer](docId\:zTUZ0LdazCmL2kQmdBKCn) BrightScript method. - You can display subtitles using the [Subtitles Widget](https://github.com/brightsign/BrightAuthor-Plugins/tree/master/Subtitles-Widget) plugin for BrightSign Author and BrightAuthor Classic. This plugin uses text from a *.txt* file to display subtitles at specified time codes. - You can use the caption plugin below to display captions inside a video rather than using a separate SRT file. The closed captions must be in one of the following formats: - CEA-708 - CEA-608 - DVB in BrightSign Author ::File{src="https://api.archbee.com/api/presign/0prk6SO2dy9LdU77jB8D1/rXPfkQer4FbXl8-TF8eyv_caption-plugin.brs" label="caption_plugin.brs" isUploading="false"} # What is the smallest supported video size? BrightSign players do not support videos that have a width or height less than 64 pixels. However, a video can be scaled down beyond this limit by making the BrightSign Author or BrightAuthor Classic zone or HTML video element containing the video smaller than 64x64. To get the desired downscaling behavior, ensure that the **View Mode** of the zone is not set to **Fill Screen and Centered**, or that the element does not have an *object-fit=cover* attribute.  # How accurate is synchronization? Using the BrightWall or Enhanced Synchronization features, players stay synchronized within a few milliseconds (i.e. video and images remain frame-accurate among screens). See [this page](docId\:STOuPgRPoR4d3PdB1rHpE) to determine which synchronization option is best for your needs. The current version of BrightSign Author doesn't support BrightWall™, but does support Enhanced Synchronization. BrightAuthor Classic versions 3.8.0.x or later support BrightWall™. BrightSign Author and BrightAuthor Classic can be installed and used on the same computer.  See [this page](docId\:QQGXuaMahuCFwh7MYzJ95) for more information. # What Adobe Media Encoder export settings to use? BrightSign recommends that you encode the video using the hardware encoder, rather than software encoder (note that hardware encoding in Adobe Media Encoder doesn’t support interlaced output\*)\*. To do this: 1. Add the video file to the **Queue**. 2. Select the video file in the panel to open **Export Settings**. 3. In **Export Settings**, go to **Video > Basic Video Settings > Field Order**. 4. Uncheck **Field Order** and set it to **Progressive**. Note that **Encoded Settings** must be set to **Hardware Encoding** to do this. Other Adobe Media Encoder settings that work for Series 2 and later players are: - Frame Rate: 25 - Aspect: Based On Source - TV Standard: Based On Source - Profile: Main - Level: 4.1 - Bitrate Encoding: VBR, 2 pass - Target and Maximum Bitrate: 12 (bitrates above 12Mbps generate files that may contain peaks above 25Mbps, which affects playback synchronization accuracy on video wall presentations across multiple players). - Time Interpolation: Frame Sampling # XD5/HD5, connected to a 4K display, doesn't set 4K video mode? If the video mode is set to "auto," BrightSign players will set the highest video mode based on your connected hardware. However, “Auto” on XD5 or HD5 players will set to the best general resolution that can cope with any type and combination of content of for these platforms, not the highest resolution. For example, the “auto” setting on an XD5 or HD5 will be set to HD, not 4K. # Is Web Audio Supported? BrightSign support for Web Audio is based on the hardware capability of the player, not software. Series 4 players and older are not capable of supporting Web Audio. BrightSign Series 5 and Series 6 players support the Web Audio API when audio is played inside the Chromium HTML engine. However, audio produced by the native BrightSign media pipeline (e.g., BrightSign Author video zones or BrightScript playback) cannot be used as a Web Audio AudioNode; only audio created and played within Chromium can be processed by the Web Audio API.
