A closer look at H.264 licenses

Article
http://www.zdnet.com/blog/bott/a-closer-look-at-the-costs-and-fine-print-of-h264-licenses/2884

TLDR: Basically h264 license is paid for by hardware manufacturers for each chip. Or software manufacturers selling a license, like Adobe Creative Suite.

Basic HTML5 Embed

Sample code:

<video controls width="640" height="360">
  <source src="http://www.pixelgoat.net/encoding/markus_output/html5/fuerte.mp4" type='video/mp4' />
  <source src="http://www.pixelgoat.net/encoding/markus_output/html5/fuerte.webm" type='video/webm' />
</video>

Suggested HTML5 Video targets:

mp4 - videos play in Safari, Internet Explorer, Android, and iPhone
webm - videos play in FireFox, Chrome, and Android
flv - Flash fallback, requires Adobe Flash plugin
ogg - older format, lower quality, for old versions of FireFox


NOTE: For Android devices, I'd still recommend Webm VP8 for 100% compatibility. With Android there is spotty support for Flash, HLS, and MP4 depending on manufacturer, OS version, and preinstalled players.

Making a 720p intermediate

Many customers have been asking for a quick guide to locally crunching their large HDV, XDCAM, ProRes, or DVCPro source. These files can range from 25-100+ Mbps, and may take a long time to move over the internets.

Many VOD customers prefer a H264 intermediate for best quality and filesize:

File Format: MP4 or M4V
Video: 1280x720p H264 @ 5 Mbps or higher
Audio: 44100 Stereo AAC @ 192 Kbps or higher

If you are having audio sync issues, we recommend exporting from Apple apps using MP4 instead of MOV. Often the timescale problems with MOV files are variable framerate or custom chapter markers. Forcing Apple's MacOS core media engine to MP4 output should lock a constant framerate and solve the sync problems.

Option #1 - MPEG Streamclip: With a simple interface similar to Apple's own QT Player, we find MPEG Streamclip to be a great tool for making fast edits and exporting a high-quality mp4 mezzanine. I also really like how all the settings are in one window and can be customized very quickly without having to click thru sub-windows.


Option #2 - Handbrake: Another very popular tool, since it is a 64-bit multicore x264 encoder on both Mac and PC and very fast. Default quality is very good using the "Regular -> Normal" setting for main profile.


Option #3 - Adobe CS6 Media Encoder: If you already have one of the CS6 applications, Adobe's encoder is very good. I generally go with the 720p Vimeo HD setting.

Option #4 - Final Cut Pro 7.x: You can export a sequence directly from FCP 7 using "QuickTime Conversion". This will take about 4x longer than other methods, due to it's legacy 32-bit processing. You will also need to modify many of the settings for framesize, aspect ratio, audio codec, and single-pass. Screenshot details below.

Premiere Pro CS5 vs. Final Cut Pro Shootout

Great shootout posted by David Basulto

Apple has basically neglected Final Cut Pro 7 for years, with very few improvements since version 5. Most notably, it still runs in 32-bit mode and uses less than half the processor cores of the new Macs. Then they released the FCP X shitpile, aka "iMovie Pro", which was obviously designed by someone who hasn't made their living editing video for the past decade.

So, looks like it's time to see what Adobe's got cookin'! I'm gonna be using Premiere CS5 more in day-to-day, and will post a real review next month.

Dark Shikari's technical analysis of VP8

http://x264dev.multimedia.cx/archives/377

TLDR: Overall, VP8 appears to be significantly weaker than H.264 compression-wise. The primary weaknesses mentioned above are the lack of proper adaptive quantization, lack of B-frames, lack of an 8×8 transform, and non-adaptive loop filter. With this in mind, I expect VP8 to be more comparable to VC-1 or H.264 Baseline Profile than with H.264. Of course, this is still significantly better than Theora, and in my tests it beats Dirac quite handily as well.

Sony F3′s S-Log firmware upgrade

S-Log is a gamma curve that stretches blacks and compresses highlights so that you can manipulate the image extensively in post. It needs a high end codec (10 bit and moderate compression) due to the heavy post manipulation to be done in the grade.

Android models

JW Player embed modes

The JW Embedder currently offers 3 modes:

Flash mode - The original JW Player mode. Uses the Flash Platform to playback streaming and progressive video, images, and sound.

HTML5 mode - HTML5 offers support on the most up-to-date browsers and devices such as the iPhone, iPad, and Android.

Download mode - Download offers the widest range of compatibility, allowing users with almost any video capable device to view the content.

The player can only run in one mode at a time, and certain features (including plugins, skins, and the JavaScript API) are disabled in download mode.

Difference between Adobe FLV and F4V

Short Answer:
FLV is Flash 9, single-file h264 we know and love.
F4V is Flash 10, HTTP Dynamic Streaming (HDS) segmented streaming file similar to Apple HLS

Long Answer:
http://www.thekuroko.com/2011/06/articles/http-dynamic-streaming-getting-started/

HTTP Dynamic Streaming (HDS) allows for the delivery of streaming content over the HTTP protocol.

sample.f4m: This is an XML file created by the f4fpackager that contains the information necessary for a client player to playback the video file. There will be only one of these for each source video file.

sampleSeg1.f4f: This segment file contains the fragments that the client player will request for playback. There can be multiple of these files for each source video file.

sampleSeg1.f4x: This is an index file that contains specific information about the fragments inside the segment files. There will be one of these types of files for each segment file. The HTTP Origin Module uses the data in this file to determine the fragment to send back to the client after a request.

List of QuickTime mp4 atoms

Very useful list at
http://wiki.multimedia.cx/index.php?title=QuickTime_container

Particularly the parts about "elst" edit lists with regards to iPhone video.

Function: edit list
Contained In: edts
Can Contain: leaf atom

The elst atom contains the edit list. The edit list contains information about the times and durations that pieces of a media track are to be presented during playback. There are many Quicktime file decoders that choose to ignore this atom. This is not a good idea. The edit list atom must be taken into account to guarantee proper A/V sync on certain files.

16x16 Macroblocks

Modern video codecs do a much more efficient job when the horizontal and vertical framesize dimensions are multiples of 16. Good examples include:

SD (4:3) aspect ratios: 320x240, 432x320, 480x360, 576x432, 640x480, 720x540, 768x576
HD (16:9) aspect ratios: 432x240, 576x320, 640x360, 768x432, 848x480, 960x540, 1024x576, 1280x720, 1536x864, 1920x1080

In 4:2:0 H.264/AVC coding, each block contains 4 luminance samples (Y), 1 blue sample (Cb), and 1 red sample (Cr). Modern video decoding chips (GPUs) are optimized for playback of 16x16 macroblocking.

For HD videos, please use high video profile, see tags below. HD videos may stutter during playback on older computers or devices with low-end graphics hardware.

PROFILES

Baseline - for low definition (LD) 320x240 or smaller, compatible with older 3G mobiles
Main - for standard definition (SD) to 640x480, good for modern smartphones and tablets
High - for high definition (HD) to 1920x1080, best for big screens with a good decoder

"moov atom not found" fix with AtomicParsley

moov atom not found
If ffmpeg gives you this error when encoding a video:

moov atom not found

Use AtomicParsley (Windows) to fix your atoms:
AtomicParsley myVideo.mp4 -P

The -P flag purges some meta data out of your video that you probably didn't know about or care about. You can also use AtomicParsley to set meta data -- artist, album, etc.

See: AtomicParsley --longhelp
AtomicParley is a simple to use command line utility. You'll be encoding with ffmpeg in no time.
