The typical examples are shown in posting a file to YouTube and streaming a live event. Now that you know speed, quality of final image and size of the compressed file are the paramount importance in judging the best video compression codec, the following four parts will show you the best lossless video codecs respectively for high quality, iOS, Android and web.
MKV: It shall be mentioned that MKV is rather a container than a codec, which is the most popular container for high definition content. It simply stores the bytes from a codec in such a way that MKV-compatible applications know where to find the video, audio and subtitle data if present for playback instead of encoding and decoding the video data.
As a result, you have the option to take the format codec like H. The preference is to generate a file with size within GB region for a 2-hour HD movie. It shall be notified that if you want to make the job of choosing a codec easier with the best video quality for your iOS device, the video files shall abide by Apple's codec discipline. For the best video codec on your Apple devices, you are recommended to choose the video format codec H.
The best framerate is The audio should use the AAC codec with a bitrate of kbps. Related Sources: iPhone best video codec. Google recommends H. These web codecs are designed to reduce file size and decompress quickly, however, they take longer than real-time to compress. But when regarding to high-quality streaming across the internet, for instance, if you want to upload a video to YouTube, H. However, there is an alternative to the video codec called MPEG-4, which offers the same pedigree and is regarded as the best choice of codec for streaming under bandwidth and processor limitations.
Please keep in mind that the video codec, best or not, shall matches the format of the video you are editing. It can be used with possibly the largest number of audio and video codecs of any container which makes it very helpful. Apple developed the MOV. The standard uses the H. Since the format is used by many cameras, software support is widespread. AVCHD typically uses the. Panasonic developed the AVC-Intra format for its professional camcorders.
AVC-Intra uses intra-frame compression meaning the image is compressed one frame at a time as opposed to compression across multiple frames like AVCHD. MXF is a format designed to be a standard for file exchange of compressed video. These file formats were developed by Sony and utilize H.
Software support is growing for these formats that also use the MXF container. The value of a codec or container is how it fits into a workflow. Remember to check the specs of your hardware and software when putting together your workflow plans. By looking at the projects you want to work on, you can figure out wich codecs and containers will be best for you. Image sequences can be used for rendering video; additionally, some animation software only export to image sequences. Saving a video clip as a series of still images instead of frame based video in a single file can have some advantages.
Image sequences are supported as import and export formats by many popular post-production software packages including some used for still images like Photoshop.
You may even see better performance using an image sequence as opposed to a video file in some software because the encoding of image sequences is more simplistic. One of the biggest advantages to image sequences is in archiving. By analyzing the frame that came before the lost frame and the one that followed it, tools found in many post programs can create a frame to go in between the two; if done properly, it is often very convincing that it always belonged.
While these tools were designed to create frames for slow motion, they can be used for restoration as well. If a file containing frame-based video as opposed to an image sequence is corrupt than it can be very difficult and sometimes impossible to recover any of the footage. There are also a few drawbacks to using images sequences, however.
Despite this, depending on the types of projects you have, image sequences may still fit in well with your workflows. Odin Lindblom is an award-winning editor and cinematographer whose work includes film, commercials and corporate video. So the only downside to using these formats is that Apple and Adobe refuse to support them in their editing software. Sign in Join. Sign in. Forgot your password? Create an account.

In between, you many also work with a mezzanine codec, proxies, or pre-rendered Previews. Click on the terms below for more details. If you could only edit native formats, you probably would. Your workflow is simple: import your footage review the shots, build your sequence, edit until satisfied, and export the results.
Even if you are able to work with native formats most of the time, understanding your options means you can stay efficient with almost any content. Transcoding refers to the process of creating a copy of your file, generally for better playback. Transcodes are the same frame rates and frame sizes but use a format which plays back better on your system. For example, mobile phone footage H or HEVC can be quite processor intensive so you may elect to transcode to a codec, such as ProRes or DNx, for shorter projects, it may not be worth the time to transcode.
Proxies are lightweight copies of your source files. A proxy copy of that footage might only be a few MB. Premiere Pro allows you to create proxies during ingest, which means you can start editing right away using the source media while Premiere generates the proxies in the background.
Once the proxies are complete, Premiere automatically replaces the source files with the proxies. Rendering is when you combine Effects with your footage during editing. You do this to maintain real-time playback if your system starts slowing down. If a section of your Timeline has a red line above it instead of yellow , it means that Premiere Pro is using the CPU to process that section or clip. You can also choose Render In to Out to render everything in the section not just the Effects.
For more information, see Best Practices: Export faster. Encoding is about compression for your final output. You may start a project with hundreds of Gigabytes of footage. Encoding takes all the media on your Timeline, including all the Effects, graphics, and audio and compresses it for and optimal balance of file size and media quality. These codecs are designed to retain the image quality and details from your source footage but optimized for better playback.
Broadcasters and postproduction facilities generally standardize on mezzanine formats to streamline their workflows, but it does mean transcoding their footage before they can start.
Transcoding time is typically meaning one hour of source footage takes about one hour to transcode. This is true whether you work with the native files, or use background transcoding. Preparing ahead is the key to success. For many projects, such as shorter content with fewer different types of media, native workflows in Premiere Pro are the quickest way to work.
Some formats, such as high-resolution media or mobile phone footage, are more work for your editing system to play back. Long GOP, heavily compressed media the kind captured by most DSLRs, for example usually requires higher processing power, and this results in slower performance overall. If you do transcode your media, the most efficient approach is to use a codec that supports Smart Rendering in Premiere Pro. Transcoding to a single unified codec and format can be helpful when working with a large group of collaborators.
It simplifies the workflow when incorporating multiple creative applications not all of which may be as flexible as Premiere Pro in native formats.
