Panda introduces support for H.265

What is HEVC

H.265 or High Efficiency Video Coding (HEVC) is the next generation of H.264 which is commonly used in blu-ray encodings. It’s goal is to improve compression – not just add more – up to 50% over it’s predecessor,  while attaining the same level of picture quality. It can also support resolutions up to 8192×4320 (8K).

HEVC Background

There are two key groups that are helping move this industry forward, The Motion Picture Experts Group, and the International Telecommunication Union’s Telecommunication Standardization Sector (ITU-T). Side note: Could you please find an easier name ? Someone here is being a troll.

Their goal is to reduce the average bit-rate by 50% for fixed video quality, and higher quality at the same bit-rate, while remaining interoperable and network friendly.

Since the majority of internet bandwidth is video (I’m looking at you netflix), one can imagine by reducing the bit-rate of video while keeping quality high could significantly reduce the strain on current networks.

HEVC Frame Types

Similar to H.264 and MPEG-2, there are three types of frames: I, P, and B. These frame types are the core to video compression, but in newer codecs such as H.265, the algorithms used are becoming more sophisticated.

  • I Frame (Intra-coded picture): Like a static image, these frames are often used as references for decoding other frames. They are usually the biggest, with the most data, but are used as references for other frames to be smaller.

  • P Frame (Predicted picture): This frame uses data from the previous frame that is unchanged, and only updates the areas that have changed. This frame can use image data and/or motion vector displacements to create the frame.

  • B Frame (Bi-predictive picture): A more advanced version of P, as it looks at the frame before and after to create a frame. These frames are the most efficient for final file size, but significantly slow the encoding process.

How does H.265 work and how is it different

HEVC breaks down each frame into coding units (CU) which are small blocks ranging from 4×4 pixels, all the way up to 64×64 pixels. The old maximum size was 16×16. These blocks are then used to compare which areas of the frame to change, and which areas can be referenced from I-Frames.

There is also an increased number of modes for intra prediction, from 9 in H.264 to 35 in H.265. While that will be much more processor intensive, the larger blocks will be more efficient.

All these improvements sound great, but it needs a great deal of computational power, in some cases up to ten times. This is one of the reasons we have introduced multi-core encoders into our infrastructure. They can handle these calculations, and increased resolutions.

Encoding Tools

Each encoder can vary depending on it’s implementation and use of tools available. This includes but not limited to:

  • Intra prediction
  • Motion compensation
  • Motion vector prediction
  • Filters
  • Parallel processing

Heads up vs. VP9

There have been preliminary tests executed by the Fraunhofer Heinrich-Hertz-Institute on performance comparisons of H.264/MPEG-AVC and H.265/MPEG-HEVC and VP9.

In similar encoding configurations, H.265 saw bit-rate savings up to 43% over VP9 and 39% over H.264.

Encoding times were a totally different story, where VP9 outperformed H.265 by 7.3% and H.264 by 130%.

We’ve done our own tests, and in the example shown below, we’ve been able to get H.265 almost 50% smaller than H.264 with the same quality. Since there is no browser support for H.265 yet, you can download a chrome plugin, or play it with VLC player.

You can view the H.264 video below, which is 1.7MB, and download the H.265 video, which is 964KB.

Where the chips fall

Our initial tests show that VP9 and H.265 have similar file sizes, VP9 in conjunction with WebM seem to be more reliable for streaming. However, H.265 seems to have better image quality.

While this isn’t turning into a Blu-ray vs HD-DVD competition, VP9 does have a leg up being royalty free. Most companies have announced support for both formats, but YouTube has yet to support H.265, and is encoding most high res videos with VP9.

H.265 and Panda

The complexity and increased processing power needed for HEVC are well matched to infrastructure and software that Panda provides. We’ve recently added multi-core encoders just for this reason.

A few customers have had early H.265 access and we’re now opening up broader access. If your business is interested in being on the leading edge, email us to be a part of the private beta at


Priority on Clouds and Select/Deselect all profiles

Two new exciting features to tell you about this week! Some of you may have noticed while using our GUI of Panda – we are on a roll with new features and improvements. This week we are bringing priority on which cloud, and select and deselect all on profiles.

Priority on Clouds

priority-cloudsPanda has been built as FIFO – First In First Out, and we encode most of your videos this way. But sometimes you have some more important videos that you need to jump the queue with.

Now with priority on clouds the videos that you need encoded asap are processed outside of the queue. Any videos uploaded to that cloud will be encoded before any other video uploaded previously.

We’ve configured this to be a little flexible, as there are three settings: Low, Normal, and High. You can build a hierarchy to get important videos delivered quick, and others just when there’s availability.

Remember, you can upload files up to 20GB in size, so maybe make those larger size videos low priority, and the small ones high priority.


Select and Deselect all Profiles

This one is pretty straight forward – if you have a number of profiles in your cloud you will be able to select/deselect all of them with one click. Sometimes it’s just easier to pick the ones you don’t want instead of selecting them manually, one by one. Just small tweak to make life easier.

Panda activity widget

Keep track of all your encoding jobs

We’ve recently launched a new great way to keep track of your encoding queue, rather than logging into the app. The Panda activity web widget is an easy glance at what videos are being encoded, and those that are pending.

Data includes the filename, the profile, encoding process, and number of jobs left in the queue.

Configure it!

It’s really easy to get the widget on your website:

  1. Log into your account at
  2. Click on a cloud
  3. Under Cloud Settings, change “Enable Web Widget” to Yes.
  4. Copy and Paste the code to your website.
  5. Click Save Changes at the bottom of the Cloud Settings page.

Encode Faster with Panda Multi-Core Encoders

We’ve been experimenting with ways to increase the speed of encoding times and we’ve developed a feature that allows you to turn the knob, slam the gas pedal, or push on the thrust lever. Multi-Core encoders.

Panda’s value proposition is buy an encoder and use it as much as you’d like. Our customers love that. If you have more volume of encoding jobs, you would add encoders. Adding encoders doesn’t increase the speed of jobs – you simply can encode more at once.

Video Encoding Kryptonite

Enter Panda Multi-Core. We think we have found the kryptonite to video encoding by enabling the use of multi-core encodings. With Panda Multi-Core, you now have the ability to turn on 2-32 cores on your video encoding processes.

At this point we are testing how much faster you can encode your videos using our most popular codecs, like WebM. We are still testing how fast we can increase the speed, but it is theoretically possible to increase encoding speed by 2x, 10x or even more.

Scenarios explained

Lets say you’re currently on our Crane plan, which is four encoders. That gives the capability of encoding four videos at the same time. With Panda Multi-Core you can turn up the speed on each of those encoders by as many cores as added.


Those 4 encoders can tap into our multi-core system, and you can choose to have as many cores on each of those 4 encoders. For example, you can encode four videos at once, but with up to 32 cores each!

Its kinda like being in a water slide race against your best buds, but you just put on a jet pack.

Apply for Beta

Currently we are testing out multi-core encoders with a few of our customers and seeing great results. Do you want to reduce your encoding times by 2, 10 or even 32 times? Give us a shout!

Timestamps in Panda


A few weeks back we showed you how you could implement timestamps on your encoded videos, and we had a lot of great feedback – thank you!

A few of you also asked if this was available in the GUI as well. So, we did it! You can login to your Panda account, and select or create a new profile that you want to use for timestamps. You can check the timestamps box, and that will turn on the feature.

Currently, the options are limited, simply turning it on and off. If you are looking for more options in the GUI for timestamps, please let us know!

The video encoder adds the timestamp with FFMPG and works best with FPS of 24, 25, 30, 50 and 60.


The Program Praises Speedy Panda Integrations

We had the chance to sit down with Coe Lottis and Eli Anderson from The Program to discuss how they used Panda for their newest project. Coe is a Partner and Director of brand Strategy. He crafts concepts for their brand partners, then brings those concepts to market. Eli is a Senior Application Engineer.

About The Program

The Program is a digital agency located in Portland, Oregon with a growing client base in Los Angeles. The agency has a number of big brand clients, such as Nike, Twitter, Obey Clothing and more. Most of their clients lean on them for technology, and new and innovative ways of interacting with consumers across digital touchpoints.

The Program’s newly launched project allows users to upload their own content. This year-long project uses Panda. “It has been a fun one for us,” Coe says. Eli adds: “The app is live in production. Everything is working great.”


Ease Of Use Made Panda The Obvious Choice

For this project, The Program was looking for a cloud video encoding solution. They relied on their application engineers to pitch solutions they thought would be a good fit for the project’s needs and requirements.

0ee4f96The Program’s tech lead, Eli worked with Panda previously, so suggested it for this project. “This was the third large project integration that I used Panda for. I evaluated it along with a couple other solutions. One of the main reasons I chose it for this project is the ease of integration. I mainly develop on Ruby, and did all the integration from scratch. This project uses Ruby on Rails and Panda has great integration there.”

“What it came down to was ease-of-use more than anything,” adds Coe Lottis. “As we looked at what some of the options were, it became apparent that Panda was the right fit. Having a tech lead that was familiar and comfortable working with Panda made it our obvious choice.”

User Integrations Makes Panda A Turnkey Product That The Program Recommends

Panda can easily be integrated using a web interface, javascript API or other integration. The Program sees this as one of its key benefits. Eli used Panda’s Ruby Gem to integrate. He goes on to say, “I also really like the debug console that Panda has for uploads, and being able to send messages back to the application. It’s super handy. The tool is set up well, and is easy to use.”

Coe LottisWe asked Coe if he would recommend Panda for similar solutions. “I would suggest Panda for its user integration. When we have a large project that takes upwards of a year, we look for solutions that don’t require heavy lifting from an integration perspective. Panda has a turnkey solution that provides all the features we needed for the requirements of this project. We were able to roll it out with minimal effort, based on the service that Panda offers.”

Panda Doesn’t Slow The Train

Sometimes, integrating third-party tools can slow down a project path. Not so with Panda, Coe states: “When you look at having to integrate third-party systems, it can bog things down and really slow the train. It’s key for us to work with a third-party vendor, like Panda, where we can get the support and information that we need in a timely manner. You can hit hurdles when you work through certain levels of integration that sometimes aren’t necessary. It may boil down to a third-party service not remaining focussed on what their piece is. Panda focusses on what it does and does it really well. It’s allowed us to plug in and keep moving along.”

Panda’s Pricing Sweetens The Deal

In addition to ease-of-use and ease-of-integration, Coe Lottis goes further to say: “The costs are great. Panda’s pricing model allowed us to hang on to our budget.”

Panda’s Video Encoders Get 50% More Memory

manydevicesWe’re always making improvements to Panda, and have now ensured that your video encodings run faster and more stable than ever before as we’ve allocated them 50% more memory. Specifically we’ve found that the WebM profile has benefitted the most, as it is one of the more popular codecs for delivering high quality video over the web.

What is WebM?

WebM is 100% free, open source audio-video container structure designed to provide royalty-free video compression for use with HTML5 video. The Project releases software under a BSD-style license. Users are granted a worldwide, non-exclusive, no-charge, royalty-free patent license. WebM files consist of video streams compressed with the VP8 video codec and audio streams compressed with the Vorbis audio codec.

Why use WebM?


The WebM format was built for the future of the web. It can deliver high quality video while adapting to bandwidth changes, processing and memory allocations on each unique device. From doing hundreds of thousands of tests, VP8 delivers efficient bandwidth usage, which lowers the cost of storing and serving the video over time. Effectively, the time it takes to encode is a small hinderance for the long term benefit.

Why do videos encoded with WebM take so long?

VP8 in highest quality will take the longest. But the folks behind the project, specifically Google, have made it their next priority to speed up encoding times in the open source project.

We looked at our systems and found that WebM encodings use a lot of memory. To provide you with the best service possible, we are now allocating 50% more memory to help increase the speed, and stability of encodings.

You’re In Good Company

browsersNative WebM playback is supported by:

  • Google Chrome
  • Mozilla Firefox
  • Opera

Other browser support:

  • Internet Explorer 9 requires third-party WebM software
  • Safari for Windows and Mac OS X relies on QuickTime to play web media, and requires a third-party plug-in

Google’s WebM Project Team will release plugins for Internet Explorer and Safari to allow playback of WebM files through the standard HTML5 <video> tag.

Software and hardware support is expanding quickly and include:

  • Android
  • Nvidia
  • Intel
  • YouTube
  • Skype
  • Adobe’s Flash Player (will be updated to support WebM)

We’re here for you!

Panda’s support team is always here to help our users. If you have any further questions about WebM, or any other codec, ping us at

Timestamps in Panda videos

The following is a post explaining how to use timestamps in Panda using our API. Interested in having this feature added to the web interface? Request beta access

article-2539097-1AA6876200000578-761_634x485In Panda, it’s easy to setup the encoding pipeline with presets developed by our team – with just a few clicks, it’s possible to configure profiles for the most popular audio and video formats on the web. With that comes some caveats, such as limiting how much you can configure.

FFmpeg and corepack-3

You might have already stumbled across a chapter in our documentation titled “FFmpeg Neckbeard”. It describes how you can create encoding profiles by specifying the whole FFmpeg command by yourself, which means that everything that our FFmpeg can do is available. We’ve recently added the FreeType library to corepack-3 (it’s the newest stack we have), and that made a few new things possible. One of them is adding timestamps to videos. This can be done through FFmpeg’s “drawtext” filter.

Play time

Okay, so let’s create a new profile that, besides doing some typical transcoding, adds a small timestamp in the top-left corner. The filter that does this can be configured by passing the below argument to FFmpeg:

-vf "drawtext=fontfile=/usr/fonts/FreeSans.ttf:timecode='00:00:00:00':r=25:x=5:y=5:fontcolor=black"

The “drawtext” filter takes a few arguments that tell FFmpeg how the timestamp should be rendered, the full list is available in FFmpeg’s documentation. And, as you can see, it needs a font. The example above uses “FreeSans.ttf” – it’s one of the fonts from the GNU FreeFont library, and the whole collection is available in /usr/fonts/ directory, so the following values of “fontfile” will work on Panda:


Now we can apply this knowledge to a profile in Panda. There are plenty of examples of creating new profiles in “FFmpeg Neckbeard”, and basically adding a timestamp is as simple as adding the filter argument to the command. The important thing is that you use corepack-3 – “drawtext” will not work with older stacks. That’s how this would look like in Ruby:

require 'panda'

Panda.configure do
  access_key "your_access_key_123"
  secret_key "your_secret_key_42"
  cloud_id "id_of_the_target_pand_cloud"
  api_host ""

drawtext_args_map = {
  :fontfile => "/usr/fonts/FreeSans.ttf",
  :timecode => "'00\:00\:00\:00'", # timestamp offset
  :r => "25", # FPS of the timestamp, for 1:1 ratio it should be equal to the FPS of input videos
  😡 => "5", # x and y specify position of the timestamp
  :y => "5",
  :fontcolor => "black",

drawtext_args = { |k, v| "#{k}=#{v}" }.join(":")

  :stack => "corepack-3",
  :name => "timestamped_videos_v2",
  :width => 480,
  :height => 320,
  :video_bitrate => 500,
  :audio_bitrate => 128,
  :extname => ".mp4",
  :command => "ffmpeg -i $input_file$ -threads 0 -c:a libfaac" 
              " -c:v libx264 -preset medium $audio_sample_rate$" 
              " $video_bitrate$ $audio_bitrate$ $fps$ $filters$" 
              " -vf "drawtext=#{drawtext_args}" -y $output_file$"

The result (the original video is on

That is nice, but we can do better. The timestamp could be more visible and in a better position – by using different “drawtext” switches we can add a background to the timestamp and place it near the bottom, centered. Using drawtext’s built-in variables we can even do this independently from video’s dimensions. The following does exactly that:

drawtext_args_map = {
  :fontfile => "/usr/fonts/FreeSans.ttf",
  :timecode => "'00\:00\:00\:00'",
  :r => "25",
  😡 => "(w-tw)/2", # w - width, tw - text width
  :y => "h-(2*lh)", # h - height, lh - line height
  :fontcolor => "white",
  :fontsize => "18",
  :box => "1",
  :boxcolor => "black@1", # 1 means opaque
  :borderw => "5",
  :bordercolor => "black@1"

And the final result:

Panda Now Supports Google Compute Engine – Experience Speed Increases Of Up To 50% Faster

Here at Copper, we’ve been busy working to bring you the best performance for your app. We’re really excited to announce that we have added Google Compute Engine as an encoding option to Panda.

panda-gceGoogle Compute Engine Benefits

With Panda being deployed on Google Compute Engine,  the result is astounding.  Encoding videos can be up to twice as fast as previous options. Our users can now experience speed increases of between 30% to 50% for standard encodings within Panda.

Google Cloud Storage

When users upload video to Panda and choose Google Compute Engine, it encodes via GCE and then we transfer it to your Amazon S3 account, just like always. In the near future, we’re going to add support for Google Cloud Storage for those of you  who would prefer to use it. If you are running on Google Cloud exclusively, you’ll soon be able to leverage it’s full benefits with Panda.

Panda optimized for Google Compute Engine

You’ve been asking for multi-cloud support and we’re delighted to be working with our partners at Google to get here today. We completely reimagined our deployment process to support GCE as we take advantages of the inherent infrastructure differences between public cloud vendors. Panda was originally built on certain features of the AWS infrastructure, so we went back to the core and re-wrote them to optimize for GCE. And now you can see the result of this in even faster encodings.

We’re thrilled to be able to bring you the best in cloud video encoding. If you have any ideas or suggestions to help us do this, let us know at

Panda Adds Support for Retina with Apple Live Streaming

We’ve now made Panda even better for developers who want to implement Apple live streaming through HTTP Live Streaming (HLS). We’ve added an additional “resolution” tag which the video player is able to choose the best stream resolution. By the way, the tag is optional, but recommended if the variant stream includes video.

What is HTTP Live Streaming?

HTTP Live Streaming (HLS) allows you to stream live and on-demand video and audio to an Apple mobile device. As an adaptive streaming protocol, HLS has several advantages:

  • Multiple bit-rate encoding for different devices

  • HTTP delivery

  • Segmented stream chunks for live streams over widely available HTTP infrastructure

How does HTTP Live Streaming work?

HLS lets you send streaming video and audio to any supported Apple product. It segments video streams into 10-second chunks that are stored using a standard MPEG-2. HTTP Live Streaming also provides for media encryption and user authentication, allowing publishers to protect their work.

How does a stream get into HLS format?

  1. The video and audio source is encoded to an MPEG-2 transport stream container, with H.264 video and AAC audio, which are the codecs that Apple devices support

  2. Output profiles are created (a single input stream may be transcoded into several output resolutions depending on the device)

  3. The streams are segmented, and an index file is used to keep track of the segments

How do HLS downloads work?

The user downloads the index file via a URL that identifies the stream. For a given stream, the client then fetches each stream chunk in order. Once the client has enough of the stream downloaded and buffered, it’s displayed. Remember to use the <video> tag to embed HTTP Live Streaming, and use the <object> or <embed> tags only to specify fallback content.
