Note that this page is something of a "beta". Depending on traffic and interest, it could be expanded on, or could go down completely at some point. Few main items that have a bearing here: It originally used about GB of space on a dedicated server for all the images and video clips. This expense was a little hard to justify for one page, so I recently dropped all the video but kept the images about 9GB. For reference, the entirety of mattgadient. These are really time consuming to process encode, generate screenshots, etc and put together a custom page for.

This page is pretty bandwidth-intensive for visitors. Unlike the write-ups on this site which even dial-up can handlethis page only provides a reasonable experience for those on quick connections. If you feel strongly one way or another really like this page or could do without it for exampleplease leave a comment. It would also be helpful to know what in particular you were interested in Did you just want to see x at different bitrates?

Were you wanting to compare x with VP9? Something else? This page contains a number of Star Wars: The Force Awakens encode clips, allowing you to compare the result of different encode settings. Output from all 4 main encoders can be found below at both p and p, with 10 different bitrate settings all speeds. A few things to note: p and p refer to "pre-cropped" versions. Once black bars were cropped, the dimensions became x and x respectively.

Bitrate-based encodes all used full 2-pass to try and get the file sizes as exact as possible for fixed-bitrate comparisons between encoders. Only medium speed is provided for RF based encodes. This is not a bug: the encoder simply did not have enough bitrate to work with in those situations. VP8 and VP9 appear to enforce minimum bitrate thresh-holds.

The video clips that used to be on this page were 1m47s in duration - these clips are what the "Video clip size:" sections are referring to. They were comprised of the following time periods from SWTFA, all merged into a single video: 9m15s-9m50s, 56m07sm29s, 1h14m08s-1h14m58s.

April 20, Images have been restored. Instructions This section lets you see the results of 2 encodes, side-by-side.Handbrake has recently upgraded to the new 1. For users who plan to encode H. The following part will show you how to encode H. Lauch Handbrake on your computer, Input the file you want to be transcoded by clicking the large Source button and then File clicking Folder allows you to easily set up batch encodes.

Then set a destination by browsing to whatever folder you desire. Also make sure to change the container from MP4 to MKV so that you can embed subtitles if you want to. Head to the Picture tab, and set Anamorphic mode to strict. Also check to make sure the automatic cropping feature has detected the correct settings.

Sometimes it will erroneously crop out a few pixels on any side, but you can address this by switching to custom with 0 set in every location box. If, however, you have a video encoded inthe cropping feature will automatically crop out the black bars at the top and bottom. In the Filters tab, you'll only want to modify these settings where necessary, leaving everything else 'off'.

If a TV show is interlaced, for example, it's a good idea to set Decomb to Fast as this will only deinterlace frames that are visibly interlaced. If you want to remove noise or grain from a source, setting Denoise to hqdn3d with a custom preset of is a solid choice. In the Video tab you'll want to select some specific settings.

Make sure framerate is set to 'same as source' and that the 'Use advanced video tab instead' box is unchecked.

Then, select an x preset of Medium by adjusting the slider down from the default Ultrafast setting. On the next page I'll explore how the x preset determines encode times, file sizes and quality, but basically you want to leave it on Medium for the best balance of encode time and file size.

Setting it higher will result in a larger file and faster encodes, and setting lower will reduce the file size at the expense of significant longer encode times. As for quality, set this to Constant Quality with a value of 23 for p videos, and slightly higher 22 for p videos. This is the slider you'll want to experiment with the most: adjusting it closer to 0 gives better quality and higher bitrates, while moving it the other way has a negative effect on quality and delivers smaller files.

I find 23 to be a great balance between quality and file size, although if you're willing to put up with more compression artefacts, experimenting with 25 or lower is a good idea. However, I wouldn't go any lower than 30 or any higher than 15 for the best results. If your source has only 2. Here you might want to play with bitrates to whatever you desire, although I think delivers great quality for TV show audio. From here you can also "burn in" subtitles, which codes the text into the video stream so you can see the subtitles on video players that don't support in-file subtitles though you can't turn off the subtitles.

Setting subtitles to "forced only" tells a video player to display subtitles even when the audio track matches your set language: this is useful for displaying a subtitles when dialogue isn't in English; for example, during alien conversations in a sci-fi film.

Optional: Save these settings as a preset so you can revisit them easily in the future. Click Start and let the encode happen, which may take a considerable amount of time depending on your hardware. After the encode is done, text saying'finished' will appear in the bottom left corner. If you are looking for a fast way to encode H.So Handbrake 0.

Note that since v0. First, a quick image to give you an idea as to what Constant Quality entails…. Constant Quality — Usually this is the preferred method. This targets a certain level of quality throughout your video s. The advantage to Constant Quality is that your videos all tend to look consistent. RF — Sliding to the right lower numbers lead to better quality. Sliding to the left higher numbers result in lower quality, but lower filesizes too. Most people experiment to find an RF value that looks good enough to them at a file size they can handle, and use that RF value most of the time, deviating slightly when need be.

RF examples — Here are a couple screenshots taken at different RF settings one at 20, and one at 30 to give you a very rough starting point click for a larger view :. And an image to give you an idea as to what Average Bitrate entails… click for a larger image.

MODERATORS

Average Bitrate — Using this and a calculator, you can aim for a specific file size given a certain video length. Helpful if you wanted each of your movies to be exactly MB for example. Advantage to Average Bitrate is that you can effectively pre-determine your file size.

Or maybe the file size was higher than it needed to be. Online bitrate calculators are the easiest way to do this. All episodes should look consistent. The problem is that this time, Episode 1 got more bitrate than it needed. Unfortunately, that means my total filesize for 4 more episodes similar to the above would now be MB instead of just MB.

Play with RF values until you find values where the video looks good enough to you on the devices you play back from, at file sizes you find acceptable. As mentioned above, this has a different effect depending on whether you went with Constant Quality, or Average Bitrate. Using the 7 slowest settings will find ways to fit that quality into a lower file size. Using the 2 fastest settings will result in a larger file size. Either way, it should look about the same. Note that the 3rd setting very fast behaves very oddly with Constant Quality and I suggest you avoid using it.

Going with faster settings here will result in less quality. Details: This is where the time tradeoff comes into play.

The veryslow preset is about the most hard-core anyone should typically get, and it can take a long time even on a quick machine. Keep in mind that there are diminishing returns as you get slower.Having spent time reading the standards recently and implementing some toy decoders I've noticed a pattern in video codec designs, starting from the very first one: H. Of course they do get more complex over time, but it seems like a cycle that alternates between incremental-yet-significant changes and huge redesigns that don't seem quite worth it.

Please don't use code formatting when not necessary, it's really hard to read on mobile. Yes they are all built on top of previous innovation and work. So it is a long evolution in terms of video codec. And there is H. It is an evolution, but technological evolution doesn't necessarily follow an exponential curve. It took many years for H. The next version may take even longer.

Innovation is slowing, and it has pretty profound effects for a variety of industrial sectors. Some features do get dropped, but in the majority later standards are more complex.

Havoc on Feb 5, Recently you've begun to see a lot of x releases though, usually with HDR, the only significant feature x can't provide. For sub-4K SDR content there's really no incentive for pirates to switch to x, it's just a nuisance. I worked for a large post house, and developed a backend pipe line for the artists to be able to submit their output to the farm to create optimized h. Eh frankly, x is not worth it unless you're an expert encoder or don't care about transparency.

If you're not making multiple test encodes and fiddling with the encoding options, you should stay on x What's actually in the Blu-Ray files that makes them so large? Nothing interesting. It's just that it's inconvenient to mass-pirate at those sizes. Lots of pixels and lossless multichannel audio. So it does come down to time though. IntelMiner on Feb 6, Anecdotal evidence. But doing H. Ripping it all to my hard disk resulted in roughly 1.

ComputerGuru on Feb 6, The image you linked to exhibits horrible artifacts - but then again, you saved the screencap as a JPEG then uploaded it to a service that likely further butchers the image. It looks like VLC at saved it as a 1.

Besides the weird new social stuff they're still by far the best image hoster I know. If you compare to similar file sizes or even half the size for x CPU encoding the quality is a lot better. As you note, the size is a bit larger than probably could be achieved I also have encoded a bit using my GTX for hardware, but the quality:size difference was a bit much.

Currently using an ik nearly 5yowhich doesn't have a the current intel hardware encoding options either.Thankfully, though, third-party projects exist that allow you to use the software from a standard GUI. Axiom is one of them, a relatively straightforward app that packs the features offered by FFmpeg into an intuitive user interface. It enables you to convert media files to multiple formats, as well as resize and crop videos.

The application is available in two variants: one that requires FFmpeg to be downloaded separately and one that includes all the required components.

Axiom can be launched from any location on your PC, and it does not require installation. Its configuration file is not stored in the program folder, however, so it is not fully portable. The app generates scripts that are run in a command-line window based on the parameters defined by the user, but the whole process is very intuitive.

You can perform the conversion directly, as well save the script for later use. Axiom enables you to convert media files to a wide range of formats, resize videos to certain aspect ratios, cut them down to size and even crop them.

Moreover, it is possible to process multiple files in batch mode by selecting the source folder and specifying which extension should be included. As far as the actual UI is concerned, it features a fairly straightforward layout, and you even have several color themes to choose from.

All in all, Axiom is a great choice for users who like the capabilities of FFmpeg but prefer not to use the command-line. It is certainly intuitive, and it can be deployed with very little effort. User-friendly GUI for FFmpeg that enables you to take advantage of the software's capabilities without having to write your own scripts. What's new in Axiom 1. Axiom was reviewed by Catalin Chelariu.

So for a newbie it can be quite hard to make x perform well without sacrificing far too much CPU power, as x is significantly more taxing on the processor than x The Blu-Ray source material is H. Also, both encoders are running in bit color depth mode instead of the common 8-bit, meaning that the internal arithmetic precision is boosted from 8- to bit integers as well. The mode of operation is 2-pass to aim for comparable file sizes and bitrates.

The encoding speed penalty for switching from x to x at the given settings is around a factor of 8. This is done, because at maximum level, WebP does lossless compression much more efficiently, so the pictures are smaller.

Specifications :. Here are the source material encoding settings according to the video stream header:. The avconv commandline for that looks as follows:. Note that you should always specify the correct frame rates -r for input and output, or the bitrate setting of the encoder will be applied wrongly! Each comparison is done in two rows: H. Left: Blu-ray reference image, top row: H.

And yep, it shows. When comparing the 1Mbit shots, it becomes clear pretty quickly that x manages to preserve more detail for the parts with lots of motion. You can spot that easily with all the aliasing artifacts on the raindrops. Moving up a notch, it becomes very hard to distinguish between the two. There are still differences between the two 2.

Maybe the colors are a little off or something, but when seen in motion, distinguishing between the two and the original becomes virtually impossible. Given that we just threw a really difficult scene at x and x, this should be a trend to continue throughout the whole test.

Now this is extreme at 1Mbit! Looking at H. Detail loss all over the scene is catastrophic in comparison to the original.

Tons of raindrops are simply gone entirely, and the texture details on the tower and the angled brick wall of the house to the left? Almost completely washed out and smeared.

We can now see details on the walls as well, even the steep angle one on the left. The only serious issue is the red light bleeding at the tower. At the next level, the differences are less pronounced again, but there is still a significant enough improvement when going from x to x at 2. Also, the textures on the walls are a tiny little bit more detailed and crisp. Once again though, x is bleeding too much red light at the tower. We get lots of block artifacts now. Some of the low-contrast patterns on the ironing board are being smeared out at a pretty terrible level.

Also, the bokeh background partly shows block artifacts and banding. Also, outlines and sharp contrasts are more well-defined, and the low contrast part is done noticeably better. The steam is only slightly better with x, outlines are slightly more well-defined, and the low-contrast patterns are slightly more visible.GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together.

Currently the version of x which includes this addition is far from a release, so this is just meant as a reminder for a future version of HandBrake maybe 1. Recently x added a animation tune preset. Just building HandBrake with the current x default branch doesn't add this tune option I tested itso it seems this has to be registered somewhere in libhb?

I don't know how or in which file, so I couldn't come up with a patch. I think in a few days, you can use x v3. In these version u can use the preset Animation.

I have tested the preset also in Handbrake. I use the commandline for this. You can test both with an old animation film. I have the settings here and it's run without any problems. But, with x 3. I think the official 3. Given the number of times x has repackaged a release, we'll probably give this at least a few days if not a week or two to settle before updating.

Luckily after some complains, they fixed this before releasing 3. Did the Tune animation also come to Handbrake? I have see, hevc is update to 3. But the new animation tune did be missing. Oh, you are right. Works for me too. Thats the issue. So its an x problem and needs to be fixed upstream.

I have opened a bug for that. Would it be possible in the meantime for HB to fix this internally with a patch for x? Something like:.
