H.264 is a well-known video compression standard for high-definition digital video. This format supports 4K and up to 8K Ultra High-Definition. Learn more..


BD3D2MK3D is a GUI to convert movies from 3D BDs to 3D MKV video files in Full or Half Side by Side, Top & Bottom or Frame sequential format, encoded in h264 with x264 (or in h265 with x265). Since v0.87, BD3D2MK3D can also accept lossless 3D AVC+MVC files created with MakeMKV as input.

H.264 is a remarkable piece of technology. It is the result of 30+ years of work with one single goal: To reduce the bandwidth required for transmission of full-motion video. Es existieren in H.264 zwei verschiedene Arten von I-Frames: normale I-Frames und IDR-Frames (Kurzform für instantaneous decoding refresh). Sehen wir uns folgende Bildsequenz an: P1 IDR P2 P3 I P4 P5. Beide I-Frame-Typen sind vollständige Einzelbilder, d.h. sie selbst enthalten keine Referenzen auf andere Frames.

The h264 format doesn't include this information. The frame rate is not necessarily constant. However, it can possibly be calculated by examining the file, and supposedly avprobe can do this:

Wiegand: The H.264 | MPEG-4 AVC Video Coding Standard 4 Identical specifications have been approved in both ITU-T / VCEG and ISO/IEC / MPEG In ITU-T / VCEG this is a new & separate standard • ITU-T Recommendation H.264 • ITU-T Systems (H.32x) will be modified to support it In ISO/IEC / MPEG this is a new “part” in the MPEG-4 suite

H264 frame format

Frame coding: • Type 1: the complete frame is coded as a separate picture • Type 2: the frame is scanned as macroblock pairs, for each macroblock pair: switch between frame and field coding Macroblock Pair 02 1 3 4 5 36 37 … … All H.264 frames are split into 16x16 pixel squares named macroblocks. Each macroblock is encoded separately. Macroblocks can be split into sub-blocks down to 4x4 pixels, see Figure 2. Macroblocks can be of the same types as the frame types enunciated in Section 3.1. An I-frame can only contain I-blocks, a P-frame I- and P-blocks and a B-frame I-, P- and H264 is the most common codec to use, creating good quality videos with relatively small file size.

Keyframes are full frames of video in the compression scheme.

Any idea how to convert that to a playable format is welcome. Share ffmpeg -i input.h264 -c copy output.mp4. That will simply copy the raw contents of the input. h264 into output.mp4 . But it will now Maybe even force a frame rate

Scrubbing and editing has been painfully slow and I've started using proxy files instead. Those files use QuickTime and the gopro cineform format. They are super fast when ed I have streaming H264 video that I want to create jpeg still images of every X frame. I am using the UMC video decoder example to decode the H.264 video to a "raw" format (I'm using RGB).
