Since we’re focusing on ATI Stream this time around, I’d be remiss not to tell you a bit about the platform’s top application to date, CyberLink MediaShow Espresso. Last year, Badaboom set the bar level among transcoder applications. This year, Espresso raises it to a new high. Espresso embodies nearly everything I think a transcoder should be: point-and-click simple, powerful under the hood, broadly compatible, and crazy fast. The app sells for $39.95, and for those who do a lot of media migration among devices and across different PC platforms, it’s worth every penny. CyberLink has optimized Espresso for Stream, CUDA, and multi-threading under Core i7.
The main UI area is for displaying thumbnails of your video files. There are browse buttons in the top-left for finding files or folders, but I find it’s easiest just to keep a Computer window open and drag-and-drop into Espresso with impunity. Once you’ve got your files on the table, so to speak, simply select which one(s) you want to convert, then look to the top-right for the target buttons. These are Apple Devices, Sony Devices, Microsoft Devices, YouTube, and Other Formats. Click any one of these and you’ll get a Convert pop-up window offering choices for device type (i.e., PSP or PS3), target resolution and screen width (4:3 or 16:9), target file name, audio format, target folder, and whether or not to use GPU acceleration. Devices will have a “Smart Fit” profile that contains recommended settings if you either don’t know or don’t care about the device’s output parameters. If the device profiles don’t fit your exact needs, you can dive into the Other Formats screen to custom create any output profile you like.
One of my favorite features in Espresso is batch processing. Most transcoder apps haven’t been updated enough to make decent use of multi-threading and crunch on more than one video file at a time. Espresso can convert up to four files simultaneously. This brings up an interesting point about GPU load. Throughout all of the tests you’ll see here, we encoded one file at a time. As GPU-Z reported it, this resulted in maximum GPU loads on our HD 4890 card of roughly 28 to 33 percent. Why, we asked, would Stream make such low use of the GPUs resources? AMD replied that it was to leave room for additional simultaneous jobs, like if you wanted to accelerate 10 video tasks concurrently. Fair enough, although it seems logical to apply an overclocker’s mindset here: if you’re only doing one thing, crank it as fast as it’ll go. If you add more tasks, then throttle back as needed to balance the jobs.
But whatever. I threw a DVD rip folder into Espresso and batch exported it into an iPod classic profile. You can see the work in progress here. CPU usage averages between 70 and 90 percent, and the GPU load jumps to almost 50 percent. So maybe it really would take 10 jobs to redline the processor, although it seems the CPU will likely bottleneck long before the GPU does.
Other notable Espresso features include automatic synching of converted videos with iTunes and integrated uploading to YouTube through your account. I like software that makes my life easier, and Espresso is now on my list of must-haves.
Keep in mind that while Espresso can import over 20 video formats, it only exports four basic file types: MPEG-2, MPEG-4, MPEG-4 AVC, and WMV. Additionally, note that AMD and Nvidia are only accelerating source material in MPEG-4, layer 10 format, better known as AVC or H.264. This shouldn’t be confused with MPEG-4, layer 2, better known in incarnations such as Nero Digital, DivX, and Xvid. Not least of all, watch your target formats for which will be accelerated and which will not. Again, H.264/AVC gets a boost but MPEG-4, layer 2 does not. MPEG-2 accelerates under Stream but not CUDA. Perhaps a cheat sheet would help.
There’s only one thing missing in Espresso. If you’ve tried enough encoders and you’re fond of either archiving your DVD rips or viewing them on various non-disc devices, then you know the value of being able to take a folder full of VOB files and having the encoder app spit out a single file of the main movie in the format you desire. As one example, Corel’s DVD Copy excels at this, but, alas, it won’t batch encode (it only queues multiple jobs) and it doesn’t support GPU acceleration. According to CyberLink, DVD image conversion is “high on the list for the next [Espresso] version.”
