Can you please share the full ffmpeg syntax used for converting the H.264 files to H.265?
- jonnycomputer 6y agoI recently did this, and used this to guide me: https://unix.stackexchange.com/a/38380/86174 https://unix.stackexchange.com/a/38380/86174
- BelenusMordred 6y agoIf you can spare the time I'd also add a slower type preset in there for better compression. eg. -preset slower # You control the tradeoff between video encoding speed and compression # efficiency with the -preset options. # ultrafast, superfast, veryfast, faster, fast, medium, slow, slower, veryslow. # Default is medium.
- LeoPanthera 6y agoIf your videos are already h.264, you probably should not convert them to h.265. You'll lose some quality to generation loss and the difference in size is not huge.
- viraptor 6y agoYou're responding in context of an article which says: > "what if I convert my screen recordings from H.264 to H.265?" Well, two things happend: My files shrink to 6% (not a type) Sounds like the difference can be huge.
- mirthflat83 6y agoYeah so if he re-encoded his video in H.264 I bet he would have seen a similar level of compression.
- gnopgnip 6y agoThe article doesn't make any claims to the quality, you could reencode the same video to quicktime or mp4 with a similar final size depending on what quality settings you use
- janandonly 6y agoThe author here. :-) Sorry for my lame English. I really should not write blogs after midnight... Anyways, a lot of you are asking for what command-line options I used for FFMPEG. So here it is: ffmpeg -i input1.mov -c:v libx265 -tag:v hvc1 output1.mp4
