There are several steps in the video process that use codecs.įirst, the camcorder takes the video stream from the camera sensor and compresses it for recording. Codecs are getting better all the time, but the perfect one has yet to be developed. The holy grail is a codec that gives maximum quality with minimum file size. Lossless codecs create better video, but don't typically do as good a job of reducing the file size, so most commonly used codecs are lossy. Other codecs are "lossy", and that means that you loss some of the video information during compression. Some codecs compress the video in a "lossless" manner which means all of the original data is preserved.
Hardware or software uses the codec to take a raw video stream and compress it into a usable video file.
A codec, or “ coder/decoder,” is a formula or mathematical process for compressing video files so that they require less storage space and can be used more efficiently in playback and non-linear editing systems. You can find some discussions about that topic here. I use Main Concept for no specific reasons. VEGAS Pro also harnesses the computing power of the most popular GPUs to speed up render times to the popular AVC and HEVC formats, making renders up to twice. It's OK to switch to "main" if you want to have faster rendering times.įinally - you have to decide whether to use Sony AVC or Main Concept AVC. Using H.264 codec, youtube recommends using high profile (which improves quality a bit, but increases rendering time). Interlacing is recommended to be off for youtube ("Field order: None (Progressive scan)"), but if your footage is interlaced, I would stick with the same setting.
But you can rather safely cut the framerate in half, converting 50fps into 25fps or 60fps into 30fps. I would not recommend rendering a 30fps video into 25fps or something like that, as the resulting quality will be rather poor. The framerate should match that of your footage. You now have your Sony Vegas supported format videos. Once it is complete, a prompt message will appear requiring you to choose if to open the folder. By clicking the 'Convert' button, you will start the conversion process. Likely one of those is giving Vegas trouble, and the ones that work have a different, more acceptable (to Vegas) codec.
mov according to your post, Vegas and QT did work just fine with i7. Here, you can choose 'MOV', format supported by Sony Vegas, as an output format for your video. Open the file in Quicktime, go to Window-Show Movie info, there you will find the video and audio codec.
These files import to Sony Vegas Movie Studio Platinum 9 ( trial ) without the audio track. there are lots of codecs that could be used to make a. Hi, I'm a Sony Vegas newbie who has been using Windows Movie Maker with my RCA Small Wonder EZ201 pocket camcorder ( 2+ years old ) to create.
But below around 2,000kbps you may want to consider switching to a lower resolution (e.g. use the QT player to inspect the video properties . Although Sony claims that Vegas support most commonly-used video codecs, including MPEG, MP4, M4A, MTS, MOV, SWF, AVI, WAV, WMA, AA3, and FLAC even with 1920. You can play and lower the bitrate as long as the resulting quality is OK for you. Select variable bitrate to get the best possible quality. 400MB into 12 min corresponds to 4,000kbps, which is close to youtube's minimum recommendation.
Youtube recommends a bitrate of at least 5.000kbps for standard, and 30,000kbps for high quality 720p video. I've created my own Sony Vegas rendering templates following those guidelines: Some considerations for coding H.264 videos for Youtube.
