![]() ![]() My computer is running Ubuntu 14.04 LTS, but I also have a virtual machine with the latest Ubuntu version, in this case Ubuntu 15.10, and I tried in both.įfmpeg - i MVI_0047. ![]() Back to the drawing board, and I decided to give VP9 a try using ffmpeg/avconv using instructions here and there. Please make sure you are uploading a supported file type.”. If you happen to have a second generation Nvidia Maxwell graphics card you may want to check Nvidia Video Encoding SDK for speedier encoding.Īll was good until I decided to upload a test video, and I soon discovered that neither YouTube nor Vimeo would support H.265 with the former ending the upload with “The video has failed to process. So I tried again H.265 encoding in Handbrake in Ubuntu 14.04, and discovered that adjusting CRF (constant quality factor) to 25 with H.265 was roughly equivalent to 20 with H.264, and both the compression ratio and encoding speed were greatly improved compared to default settings with a minor degradation in quality. So this week-end I investigated how I could reduce the upload size, and going with H.265 codec appeared to be a good idea at first. 1080p videos are all good, but my Internet connection’s upload speed is limited to 512 Kbps, so for example uploading a 20 minutes H.264 video shot at 1080p30 may easily take 10 hours, even after some processing with Handbrake.
