We need chapter markers with video exported with the H264 codec so we need the quicktime wrapper (since Premiere and the Media Encoder do not support chapter markers). The problem: quicktime H264s are far inferior to MP4 H264s when exported through Premiere or AME. Why at the same or higher data. CEA-608 caption. Download Link 3. The CEA 608 or just the CC codec is the means to ensure that. Click “Common Video” “MOV – QuickTime (.MOV)” to get the optimized output file for MKV to QuickTime conversion on Mac El Capitan and macOS High Sierra. Tip: You can also check the “Settings” box, and set video codec, video size, Bitrate, frame rate to get a decent video you want on your QuickTime.

What's x264(H.264/AVC)?
X264 Codec Windows 10
x264 is a free software library developed by VideoLAN for encoding video streams into the H.264/MPEG-4 AVC format. Usually we confused x264 with H.264, which is not wrong, but not accurate as well. Actually, H.264 is a specification for compressing video, aka MPEG-4 part 10 or AVC; while x264 is a very high quality encoder that produces remarkable quality H.264 compatible video-stream. It is almost exclusively used by all the open source video platforms like ffmpeg, gstreamer, handbrake etc. In short, H264 is a format, and X264 is a software library to create H264 files.
What's x265(H.265/HEVC)?
And x265 is a free software library and application for encoding video streams into the H.265/MPEG-H HEVC compression format, and is released under the terms of the GNU GPL. From the definition, we got to know x265 is a successor to x264. Similarly, there are also confusion with x265 and H.265, which goes the same with x264 vs H.264. However, in daily life, it's not that exact for x264 vs x265 and H.264 and H.265. That is to say, we usually lumped together H.264 vs H.265 and x264 vs x265 comparison.
