Surely you've been in a situation where you needed to make a decision to buy this or that product, but you didn't have enough information. That's why we have prepared for you comparison recordings of microphones and other products we offer. In addition, in the description of the tested audio products you will now be able to listen to, or download, an unedited recording that was recorded using the device.
However, exporting to H.264 requires a relatively powerful processor and the time required to export to this format is therefore quite long (compared to exporting to MPG2, for example). For short video sequences this may not be so important, but when exporting e.g.
It is worth considering for a 2-hour long video sequence to MPEG-4 AVC.
So if you are working with longer video sequences, this article is for you. We have prepared a test comparing the export speed of the most widely used non-linear editing programs directly from their timelines. Before we introduce you to the conditions of our test, however, a little more theory..
Nowadays, in addition to software rendering/exporting, some editing programs also allow hardware acceleration. This means that the mathematical computation is accelerated by hardware other than the processor. Currently, we know of several possibilities for such acceleration.
- CUDA
- acceleration via NVIDIA GPU (graphics card)
- Quick Sync
- acceleration through the integrated graphics chip of INTEL processors (processors gen. Sandy Bridge, Ivy Bridge, Haswell)
- SpursEngine- acceleration via a separate PCI-E card with SpursEngine support (e.g. Firecoder Blu
)
HOW WE TESTED
We tested four PC-based video editing programs -Adobe Premiere Pro CC,Grassvalley EDIUS Pro 7
,
Sony VEGAS Pro 13andAvid Media Composer 8. The subject of the test was the export of 30 minutes of unedited video directly from the timelines of the above applications. As material for the export we used native (untranscoded) footage from aSONY PMW-200
camera (FullHD 1920x1080i - 35 Mbps). The only exception was Avid Media Composer, where we had to transcode the native footage to MXF first, which of course made the whole working process on this platform much longer. Moreover, Media Composer does not provide any hardware acceleration, which does not add to its attractiveness.
When exporting from individual applications, we tried to set the export parameters in the same way. However, it is true that some applications do not provide as detailed export settings as others, which may have affected the measured export times to some extent. As for the hardware, it was the same in all cases (seePC configuration
). The export parameters were MPEG-4 AVC (H.264, VBR 18/22 Mbps, Best quality). For each application we exported 2 times (except for the aforementioned Avid Media Composer). First with software rendering only and then using hardware acceleration. Here is an overview of the technologies supported by each editing application:
Adobe Premiere Pro CC- NVIDIA CUDA
Grassvalley EDIUS Pro 7- INTEL Quick Sync
Sony VEGAS Pro 13
- NVIDIA CUDA
