![]() ![]() Changing this to 1 creates a separate thread to run the video compressor. The default is zero, which runs the video compression inline with the rest of the video stages. Using threads for video compression allows the compression to run in parallel with other stages of the pipeline, which can increase performance with systems that have multiple CPUs or CPUs with multiple cores. In the Threading section, you can control the number of threads used for video compression. Multithreaded video compressionīy accessing the Preferences dialog via Options > Preferences, you can access the Threading section. Occasionally, the hardware vendor will have a software decoder available for download on their website that can be used to play the video on systems that lack the hardware. For instance, if you use a FooBar video card to capture in FooBar Motion format, probably only those who have FooBar video cards will be able to play it. If you have video hardware installed that also comes with a video codec, videos created by it will most likely not be playable by anyone who doesn't have the same hardware. You can also use an external tool to encode to MPEG, which is playable on most modern systems, even those not running Microsoft Windows. For this reason, it is best to stick with video codecs that are installed on most systems or are easily obtained. For instance, if you use Huffyuv to encode, the recipient of the video needs to have Huffyuv or another compatible codec installed to play it. Remember that for anyone to play the videos that you create, they must have a video codec which can decompress the video. For instance, you might use 720x480 video compressed with DV during production, and in the final pass, reduce to 320x240 and encode with an MPEG-4 based codec. It is best to work with higher quality video and wait until the very end to apply the final video codec with the desired compression ratio. key frame only and higher quality over compression ratio. ![]() When creating intermediate video, prefer using either lossless video compression or video compression that is amenable to editing, i.e. Typically a lossless codec will only compress video up to around 3:1, whereas a lossy codec can get as much as 100:1. The advantage of lossless compression is that it preserves the video exactly lossy compression lowers the quality a bit, but typically gets much better compression. Lossless compression means that the compressed video is exactly the same quality as the original, whereas lossy compression discards less important portions of the video to reduce size. ![]() There are two types of video compression, lossy and lossless. This codec is then used to compress the video. To enable video compression, the video mode must be set to a mode other than direct stream copy, and a codec must be chosen in the Video Compression dialog. ![]() I got a message saying that either the file is incomplete or damaged.Raw video is very large and consumes a lot of disk space, so usually video compression is used to decrease the size of the video. Then I tried importing the Lagarith AVI file into Premiere Pro and it wouldn't import. i7 6700HQ, 32GB RAM, Geforce 1060, onSamsung 850 EVO M.2 SSD drive.Įventually I got back to the computer and Media Encoder said "done", but there was no sign of the exported file in the destination folder. As a test I just tried to export about 15 seconds of the video and it took about 20 minutes. Dragged the file in, set the export settings, hit the start button. I'm basically just trying to import the file and export it to a different format/codec. I can play the AVI file I have fine on Windows Media Player.īut when I try to import it to an Adobe product, I have problems. Hi all, while not directly related to my original post - I'm hoping you can help me out here. ![]()
