X264 vs x265 (or h264 vs h265) sizes? The resulting quality of the HEVC video will be much worse. 2gb Vs 4gb, even a 12gb down to 3gb!! X264 is the open source program (library) used to encode Bluray or any other video format into the h.264 format, ready for packaging into the desired container (eg. Have I now understood it all correctly? Or is the Bluray encoded into a x264 format (by the x264 library) which is based on h.264? So the actual PC codec is x264 and not h.264?

How do I convert x265 files to x264 as fast as possible using Handbrake? What settings do I use for this? Loss of quality is fine, as long as it's watchable. My TV doesn't support x265 files so I plan on keeping the converted x264 files on my TV. - Reddit

My player can play x264 successfully, but for HEVC or x265 (480p or 720p or 1080p) video it cannot play smoothly, the A-V sync is horrible. I need to change the codec from HEVC/x265 to x264. Any help?

X265 is a library aiming to encode videos into HEVC/H.265 video compression format. While X264 bears resemblance to X265 but it just encodes video streams into H.264. So when we refer to convert x265 to x264, it generally means a conversion from HEVC/H.265 to H.264. And such task can be done with Handbrake, the latest version 1.0.7 having been updated with better x265 support but confusing many users due to its complex x265 profile settings. For a simple entry, just check the Handbrake tutorial below and learn the Handbrake X264/H.265 encoding settings to speed up the x265 to x264 converting process.


Q: Should I convert my H.264 videos to HEVC/H.265 to save space? Will I lose quality? ------From a Quora user

Video X264 Vs X265X264

A: Yes, you should convert your H.264 videos to H.265 to save space and yes, there will be an acceptable quality loss (such loss is not visible to your naked eye). Let me explain in detail at below:

X265 vs x264 reddit

First of all, both H.264 and H.265 are excellent video compression standards to provide good video quality at a relatively small size. H.265 (High Efficiency Video Coding/HEVC/x265) is a successor to H.264 and almost double the data compression ratio than H.264. To put it in other words, you'll get a half size video when you encode video with H.265 instead of H.264. So to conserve more space, you should convert H.264 to H.265. (For more information about these two encoders, please check H.265 vs H.264.)

Second, any transcoding (in lossy formats) will generate data loss. And since both H.264 and H.265 are lossy encoders, the conversion from x264 to x265 will definitely lead to some quality loss. But such quality loss is acceptable for it’s hard for anyone to spot the quality change.

X264 Vs X265 File Size

In all, convert H.264 video (especially in high bit-rate) to H.265 will save you much space while preserving the quality. So you should convert H264 to H265.
