![]() Unfortunately it doesn't seem to follow a pattern - I encoded a test sequence in Media Encoder and Handbrake and it worked fine, made some changes and then re-encoded it the next day using the same settings and it wouldn't play correctly.Īny suggestions to overcome this would be great. I have tried Media Encoder, Handbrake and Squeeze, with a variety of bitrates, CBR and VBR settings, and the problems persist. When I encode the full motion video, this largely encodes and plays back ok, but when I encode the sequences, using exactly the same preset, when playing back it either freezes at random points, or plays back with lots of glitches/stuttering. I have tried adding a dummy audio track as well to see if it was related to that, but still no good. From After Effects I generally export a ProRes422 file and then encode from that. I have two types of content: full screen video content using library footage edited together, and full screen shows produced in After Effects where I am either animating layered Photoshop files to show evolutionary adaptation, or producing a grid of image sequences showing variations of human eyes. I am encoding some content for an exhibition, using Adobe Media Encoder and/or Handbrake. I have a problem regarding encoding for 4K playback I would really appreciate some help with. Merge Mode: If you are using B-frames as references in H.265 “merge mode”, the size of the references list should be limited to two or less.Note that the second video decoder can simultaneously support a 1080p video at up to 40 Mbps. Bitrate: For 4K videos, we recommend a constant bit rate (CBR) between 30 and 40 Mbps.Container Format: The following container formats are supported.However, we do not support the recently ratified version 2 profiles. Most Devices Presets use the broadly compatible MP4 container, while a select few use the Matroska Multimedia Container to support advanced features such as Ultra HD 4K resolution and additional. Note: BrightSign players support both H.265 version 1 profiles: Main and Main 10. HandBrake’s Devices Presets target specific devices and classes of devices, such as mobile phones, tablets, TV media players, and game consoles. If your display components do not support HDMI 2.0, you can display a 4K video at a maximum of 30p (with 8 bits color depth) for this, we recommend a Main profile at level 5.0. The following chart outlines supported color depths for 4K video: Main Profile: If your display components support HDMI 2.0, you can display a 4K video at 60p for this, you should encode the file using the Main 10 profile (10 bits of color depth with 4:2:0 chroma sampling) at level 5.1.Resolution: The maximum supported resolution is 3840x2160 or 4096x2160x24p.These models do not support 4K video encoded using H.264. Video Codec: The video must be encoded as an H.265 (HEVC) file. ![]() Note: 4K video must be played from a Class 10 SD card. These are the requirements for encoding 4K video:
