Check the input level of the audio source to make sure it's the correct level. Modify the input gain if necessary.
What to do if Adobe Premiere Pro won't load my .mp4 recording from Epiphan Pearl Mini?
Check if the selected recording format in Pearl Mini is MP4- Fragmented, as Adobe Premiere Pro does not currently support fragmented .mp4 files. Before editing in Adobe Premiere Pro, convert the clip to progressive .mp4 format by running the file through ffmpeg or a third-party software such as Handbrake to preserve both audio and video output.
What to do if the stream interrupts or the image breaks up on epiphan Pearl Mini DVR?
To diagnose image problems: * Ensure the source resolution is used as the output or recorded resolution. Up-scaling and down-scaling can affect picture quality. * Increase the Bitrate value and/or decrease the Limit frame rate value in the Encoding menu. * Check network settings including filters, routers and application settings. Packet loss can result in stream failure.
How to improve image quality on Epiphan DVR?
To improve image quality: * Ensure the source resolution is used as the output or recorded resolution. Up-scaling and down-scaling can affect picture quality. * Increase the Bitrate value and/or decrease the Limit frame rate value in the Encoding menu.
Why is video playback fine, but when I play the clip in Adobe Premiere Pro the audio and video are out of sync from Epiphan DVR?
Adobe Premiere Pro has a known issue handling video that is recorded using a variable frame rate. Convert the clip to a constant frame rate using a third-party software, such as Handbrake, before editing in Adobe Premiere Pro.
What to do if firmware upgrade fails on Epiphan DVR?
Reboot the system and try again. If the problem persists, contact Epiphan support at support@epiphan.com.
What to do if the system is not starting up correctly on Epiphan DVR?
Ensure there are no USB sticks inserted into the USB ports during power up. They may be conflicting with the internal hard drive, causing unexpected behavior.
What to do if when previewing a channel some web browsers do not play audio on epiphan Pearl Mini DVR?
The Flash (FLV) plugin must be installed for your web browser to play back audio that's encoded as PCM. Web browsers that use Flash players to preview video do not support audio that's encoded using 48 kHz MP3 or 48 kHz PCM.
What to do if captured SDI audio contains audible "clicking" sound or other audio distortions upon playback on Epiphan DVR?
Ensure audio sample rate is set to 48 kHz. Lower sample rates (i.e. 32 kHz and 44 kHz) can sometimes cause audio distortion.
What to do if certain Media players won't play encoded videos on epiphan Pearl Mini DVR?
Depending on the media player used, there could be different issues. If you encounter a playback issue, try using a different media player. Some issues we know of include: * On Windows 10, the Movies & TV app sometimes fails to playback MP4-fragmented files with MP3 audio: try changing your MP4 audio encoding to AAC. * VLC doesn't play MP4-fragmented files normally. * Streams and recordings at very low frame rates (e.g. 1 fps) are not playable in VLC media player, use Windows Media Player and Quicktime Player instead.
