Some screen recordings taken on high density displays can even produce videos at or above 3840 pixels × 2160 (4k). A 1080p video has more horizontal lines (more information), thus making the video file size larger. As you can imagine a video that is 1920 x 1080 (1080p) will have a larger file size than a video that is 1280 x 720 (720p). Larger resolution videos will dramatically increase file size. Resolution is defined by the number of horizontal lines the video has from top to bottom. The resolution of a video determines the size in height and width that the video will be created in. Takeaway: Use the MP4 file type to keep quality and reduce file size. AVI (Audio Video Interleave – Microsoft)Īnd many more! You can learn all about the different video file types listed above by reading this article. To help you not worry too much about file size, we’ve created Camtasia and Snagit video outputs to default to the MP4 file type, and will recommend MP4 in the majority of cases for online sharing. Because of this, MP4 is very popular for web-based delivery including YouTube, Facebook, Twitter and Instagram. This codec produces an MP4, which typically delivers the best quality, with smallest file size. Learn more about codecs here. You may have heard of the h.264 codec (you may not have, but hang in there). Codecs encode or compress streams of data for storage, playback and video editing on a variety of platforms. To help you understand video codecs and containers we wrote an in depth post about the differences of video files types. There are many different video formats you could export your finished video into. **If you’re new to these concepts, please don’t stop reading just because we use a lot of jargon, we will try to explain each, and by following the associated links, you may also better comprehend each one.** Below we’ve put together some helpful information to get you started on your file reduction journey! Video Format and File Type It can be hard to know where to start when trying to reduce file size. You may want to reduce file size to more easily send to your co-workers, or complete your upload to YouTube quicker. I used data Import, then ran the clips through 5DtoRGB.Video file size can be tricky and the concept of reducing video file size has many technical variables associated with it. How does this footage look to the trained eye? I didn't see any jaggies and I've noticed some very bad jaggies on some other C100 footage that is considered very good on Vimeo. Here is something a shot yesterday in my back yard. Do you think there is a difference in the quality of the image doing it this way rather than a card reader? Hi Dave, I've always used the USB cable on my 5D3 to import the footage. If however you ever seen any interlace type artefacts in the FCP viewer then check the progressive settings in the info panel. If the workflow you are using works for you and when you check the info panel in FCPX it says progressive then you are good to go. Several apps, including ClipWrap and maybe 5DtoRGB do this change for you when re-wrapping, but it's a stage I usually don't bother with because it's not required since I can do everything inside FCPX. If you import from the AVCHD structure then FCPX (and most other NLEs) see the footage as interlaced not progressive, so you ned to click on the clip in the event browser then in the inspector (cmd+4 to open) in the info tab change it to progressive. I always import from the card and not via USB.
