Sorenson Squeeze 9 Pro

df_squeeze9_1

Sorenson Media’s Squeeze encoder has always been at the top of the market for encoding features and quality. It’s now in the ninth generation of the software with standard, pro and premium versions. Sorenson Squeeze 9 Standard and Pro are Mac and Windows desktop applications, while Premium is designed to run on Windows servers. The difference between Standard and Pro is that Squeeze 9 Pro supports the encoding of Avid DNxHD and Apple ProRes (Mac only) codecs.

New for Squeeze 9 is an update of the user interface, HTML5 optimization, faster encoding and closed caption support. Another new feature is pre/post-roll stitching. This lets you attach an additional file, like a branding message, to the beginning and/or end of your video. These will be encoded together with the additional video clip(s) embedded into the same file – no editing required. As before, Squeeze supports import from files or camera devices and you can set up watch folders. All Squeeze purchasers get 5GB of free cloud storage with Sorenson 360, which they may use for private review and approval with clients or as a place to host videos that they’d like to embed into their own web sites.

The Sorenson Squeeze 9 presets are built around formats and workflows for easy access. If you want a specific preset, then it’s easier to find that in the format tab. On the other hand, if you want to burn DVDs, then getting there via the workflow tab makes the most sense. Of course, you can modify existing presets, create custom presets from scratch and save the ones you use most often as favorites. There is a large set of audio and video filters, which can be integrated into any preset, including VST audio filters already installed on your computer.

Publishing to the web or disc burning is part of the Squeeze workflow, so your presets can include target publishing destinations, like a YouTube channel or your Sorenson 360 account. One big feature of Squeeze is support for adaptive bitrate encoding. Most smaller users never encounter that, but it’s a requirement for many large enterprise-grade video sites. In this process, a set of different files with low to high data rates are encoded and grouped into a folder for upload. This permits the playback from that site to throttle performance by shifting between the files of these different date rates.

If you have a CUDA-enabled NVIDIA GPU card, then the encoding of AVC/H.264 content is accelerated. Even without it, encoding is fast. On my 8-core Mac Pro with an ATI 5870 card, QuickTime H.264 encoding speeds were comparable to Apple Compressor 4 with similar encoding settings and formats. There was a noticeable improvement in this version with WebM, which is the codec backed by Google and preferred for YouTube. In past tests , this was a real bear to encode. A one minute file might take 20 minutes. With Squeeze 9 it only took a couple of minutes for the same test.

The encoded quality is very good and gone are some of the contrast, gamma and saturation differences of past versions. When you encode QuickTime H.264 files, you can choose between the Apple H.264 and the Main Concept H.264 encoders. Both encoded results play fine in QuickTime Player, though each looks slightly different than a comparable file encoded using Compressor. This likely has to do with how the player interprets the flags within the encoded file. Generally the Main Concept H.264 version was the closer match.

Since I was testing the Pro version, I converted some Apple ProRes files to Avid DNxHD in the MXF format. Squeeze encodes these files complete with corresponding XML and AAF files. This means that you can simply drag the MXF and AAF files into an Avid MediaFiles/MXF/numbered folder. Then import the AAF files into Avid Media Composer and the encoded master clips appear in your bin. No further import or transcoding required. If you work in Final Cut Pro, Premiere Pro or Media Composer and prefer to batch encode a set of non-standard camera files into native DNxHD or ProRes media, then Squeeze is ideal as long as it’s a supported codec. If you purchased Avid Media Composer, then the standard version of Squeeze is included in your third-party software bundle. This can be upgraded to the Pro version by contacting Sorenson Media.

Sorenson Squeeze 9 is a healthy update to a top-notch encoding application and a valuable tool for any editor tasked with delivering a variety of formats. Android, iPad, YouTube, DVD, Blu-ray or broadcast deliverables – Squeeze has it covered.
