The H.264 algorithm is complicated. I fixed that by forcing the re-creation of the FFMPEG context when the frame size changes. After doing that, FFMPEG is returning the correct frame sizes for the subsequent videos (according to my tests). This fixes a memory corruption that could occur after switching between different H264 videos with different frame … 2013-10-02 The bitrate chosen is 20 Mbps, which is a safe 80% of the maximum peak bitrate allowed for H.264 level 4.0. The superbit version should be almost lossless, practically indistinguishable from the original master – a "transparent" encoding, as it's known.

H264 frame size

A single frame of that video in PNG is 1015KB. It looks like we're storing 300 times the amount of data in the video. But the file size is a fifth. So H.264 would seem to be 1500x as efficient as PNG. How is this even possible? All right, what's the trick? There are very many tricks! Request PDF | Statistical analysis of H.264 video frame size distribution | H.264 video traffic is expected to account for the majority of multimedia traffic to be carried in future heterogeneous H.264 is currently the most popular and most efficient video compression standard.

H.264 I-Frame Only ENCODER FPGA Core - High Speed Micro Footprint Our I-Frame Only FPGA core is highly optimized to be as fast and small as possible. By limiting the core to using only I-Frames, we were able to reduce the size of the core by 30% (compared to our already small H.264 Encoder Core) achieving a size close to that of a JPEG Encoder, yet provide much better compression! H264 codec and Profile The H.264 standard defines a set of capabilities, which are referred to as profiles. If you choose "H264 (NVIDIA® NVENC)", the "Profile selection menu" appears like below.

H264TS_Cutter is a HDTV-Transportstreams (AVC / H.264) cutter. The source material won't be encoded, so you can only cut on I-Frames (the program will look for it by itself). If you want to use the video playback function, a ts-splitter and an avc-codec have to be installed.

This technical report describes a GUI/frontend for ffmpeg. 264, here are some general guidelines: * For a frame size of 1920 x 1080 (full high definition), choose a data rate of 7,000-8,000 Kbps.

While the size of P frames may vary (depending on scene complexity/changes), usually P frames are far smaller than i frames. The H.264 video, 300 frames long is 175KB. A single frame of that video in PNG is 1015KB.
