Re: [FFmpeg-user] Why H264 Encoder is slower than H265 Encoder?

Hello Shi Qiu, I have two thoughts: 1. Is that the best possible experiment with only one variable changed between the two cases? It looks like the input format changed, too, although the filenames are possibly fake simple examples (simplicity is good). The H264 output has a.h264 as the

Re: [FFmpeg-user] Why H264 Encoder is slower than H265 Encoder?

Thanks Zak, I think the problem may related to the OS or the driver. I used the same input media (1080P video) on Windows 7, H264 encoder(240fps) is much faster than H265 encoder(80fps). After some tests, I've found that the problem is that SKL H264 encoder (100fps) is quite slow with old vaapi

Re: [FFmpeg-user] MXF XAVC UHD video stream modified while using the -copy option

Hi, I know this because the size of the video stream isn't the same on the remuxed file. As its duration is the same as I can play it without any problem, I think some metadata were stripped off, but I don't know which and why. You can also see this in the MediaInfo report I included in my

Media info output, as I included in my initial question. Stream size in original file is 15.9GiB and 15.8GiB on ffmpeg remuxed one. Stream size for all audio element is the exact same on both files. In addition, if you look at the report I linked, you will also see that the overall bitrate

The video itself seems fine (same duration, frame accurate), it's just that I don't know where the size difference come from and what information are lost. I tried to open the file created by FFMPEG to BlackMagic Design Resolve software, and it won't. As I don't have any problem with the
