With ffmpeg, it'd look like this: ffmpeg -i input.mp4 -c:v libx264 -crf 23 output.mp4 For x265, the default CRF is 28: ffmpeg -i input.mp4 -c:v libx265 -crf 28 output.mp4 For libvpx, there is no default, and CRF can range between 0 and 63. If libx265 is too slow use libx264 which is faster but file size will be bigger. Making statements based on opinion; back them up with references or personal experience. Then, using that information, proceed to the next step. It means there is less differences between the original and the compressed one. This will be very fast as it is "copying and pasting" the H.265 video into the MP4 container: The camera's H.265 encoder isn't as good as x265, so if you do need to shrink the file you'll need to re-encode (but be aware of generation loss): Adjust -crf and -preset to your liking. Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm). Why are non-Western countries siding with China in the UN? It can save up to 20-50% in size compared with H264 codecs retaining the same quality level. This information alone confirmed for me that I will only be using x265 or newer encodings (maybe AV1 in 2020) for storing videos going forward. shouldnt slower preset produce better picture quality? If you like I"d be happy to test one of your .ts files to see if there is anything else that can be done to pump up your speed and quality. Does With(NoLock) help with query performance? Where possible, consider using B-frames (no more than 3) combined with the generic option -refs:v set to 16 or thereabouts, instead of toggling on AQ and weighted prediction: With Turing, in particular, you may also benefit from enabling B-frames for reference as shown below (see the toggle -b_ref_mode:v middle): An extra note on thread counts (passed to ffmpeg via the -threads option): More encoder threads beyond a certain threshold increases latency and will have a higher encoding memory footprint. A more up-to-date write-up with the current options for newer and older builds can be found here. Through some experimentation I found that I personally never can really see a difference between anything lower than 22 using a Slow present. I did three CRF videos first, at 22, 20, and 18, then using their resulting bitrates created three ABR videos. What is interesting, is if we put CRF 16 - Medium encodings bitrate on this chart it would go shoot off the top at a staggering 15510kbps! All Rights Reserved.

In fact, the MPV devs have mentioned this repeatedly, don't rely on hardware-accelerated decoding for mission-critical content delivery. Between H.264 and H.265, from what I've read the difference is about 30%, which is an impressive improvement at that point, considering how efficient H.264 already was, but from a practical standpoint it's too small to justify a systematic conversion just for the sake of saving a few gigabytes (or even hundreds of gigabytes - you may end up When I transcode video to H265 with following command, I get a bitrate about 600K and the quality is almost the same as the original. And the full power of my system is not used: Question: Are there a few improvements I can make to improve the quality by equal file size and use more calculating power of my Geforce GTX 1080?

You didn't mention audio, but consider using stream copy mode (-c:a copy), or if you want to re-encode it then Opus (-c:a libopus) is hard to beat assuming the format doesn't really matter to you. Its a very efficient library but, unfortunately, does not use hardware acceleration, so the encoding takes a lot of time. So I had to ask myself: To find out I would need a lot of comparable data. That said, you can try to establish your own calibration between the current versions of the encoding libraries in your ffmpeg by running the following command, which executes two popular video quality metrics: The final lines of the console output will contain: So, run the command once with the x264 output and once with x265 and compare with different x265 outputs, till you get similar measures. ffmpeg -framerate 30 -i in.265 -i in.avi -c copy -map 0:v -map 1:a -video_track_timescale 1k fixed.mp4 Replace the framerate value with the true rate of the video. You will have to tweak A LOT of the extra complex settings of x265 encoder to even MATCH x264, let alone surpass it in size to perceivable quality, and by the time you do, you will see that x265 is just a order of magnitude slower than x264 to achieve marginally better results which is very problematic with 4k encodes. Thankfully there is a simple answer. Pretty new to this but I have one questions I cant seem to read up on, If I have a 10 bit 4k movie and I use the H265 AMD VCE video encoder, would I lose the 10 bit with the new conversion? ffmpeg - Read raw Data instead of converting to different Format, What is the fastest method to compress videos before sending in React Native Chatting app. What CRF or settings I should choose for h265 in order to achieve a similiar quality of h264?
