3/1/2023 0 Comments Does vimeo recompress uploadsI managed to get a response after step 1 ("create the video"),Ībout the second part, things are not as clear. The real question is not what we think ought to look better, but whether an unbiased or disinterested viewer can, without any cues, tell any difference.I'm following the api's guide about resumable uploads. In the case of sports or action, perhaps not much different, or perhaps 1920x1080 60p 28mbps won't offer much perceivable advantage over 1280x720 60p 15mbps. Would footage shot with the same camera, and streamed over Vimeo, look any different? In the case of flowers and fenceposts, probably not. Someone at Luminous Landscape did a similar test and found no advantage.Īnother worthy test would be to compare AVCHD1 (humble 60i at 17mbps or less) to AVCHD2 (28mbps). An extra recorder connected to an HDMI feed is an expensive encumberance. Not to bicker with "pros" who need decompressed video for complex edit effects, most people don't edit at all, and even enthusiasts can do everything or more than time permits to edit AVCHD as-is. Some people pay for high speed super bandwidth, but most cannot play HD video at all without considerable buffer time, which is tantamount to repelling many viewers from seeing a video at all. The Ninja 2 version looks a bit worse.īut, honestly, the use of any high bitrate codec is moot if everything must be recompressed in the end and streamed at 5mps or even lower. The better clips are the ones you say came from the camera, using its standard AVCHD2 compression. See any glaring differences from the Vimeo versions or the originals? Looks like AVCHD 60p does a really nice job, and gives you really small files. I was holding the camcorder and Ninja with one hand, but that also challenges the codecs. Choose your output file name and location. Select the file format you’d prefer for your video. Navigate through File > Export As > Choose. The scenes have a lot of red flowers and a lot of detail so a challenge for any codec. Here are the steps you need to follow for compressing a video using QuickTime on your Mac: Open QuickTime on your Mac. They are the same length - high bitrates have a cost. When you send a request to the Vimeo API, we return the requested data as a representation, or a hierarchical JSON object with multiple fields and values that describe a particular Vimeo resource: a video, a channel, a member account, and so on.We try to include only the data that you need based on the resource that you request. Or, if you are a member of Vimeo, you can download the originals. You can open two windows and run the two videos simultaneously. The Ninja2 Apple/Avid high-bitrate/high sampling version of the same scenes from the uncompressed output is here: The camcorder-produced AVCHD 60p at 28Mbps version is here: The edited videos were then separately uploaded to Vimeo. The AVCHD 108060p clips were edited and combined without recompression. To maximize quality I edited and converted the Apple Pro Res 422 60i clips to Avid DNxHD 60i (145Mbps), which also uses 10 bits per channel with 4:2:2 chroma subsampling, in Sony Vegas Pro. Vimeo sets limits on the files size and video formats to be uploaded. You can monitor your current quota usage, as well as find your reset date and time, in the lower left-hand corner of the upload page. Upload quotas reset every 7 days, at midnight Eastern Time. Notice that the bitrate is not only much higher, but also there is more information obtained on color (chroma). Vimeo Basic, Plus, and Pro members have a weekly quota, which is a cap on the amount of video that can be uploaded to their accounts each week. For more details, see Working with Text Track Uploads. This is a codec the pros use to edit with. Using a very similar process, you can upload text tracks to your videos for subtitles, captions, and the like. I shot with the Ninja and the camcorder simultaneously, the Ninja getting its signal from the uncompressed 108060i put out by the camcorder (and which bypassess the internal processor) and using Apple Pro Res 422 (145Mbps, yes, 145 Mbps), which uses 10 bits per channel with 4:2:2 chroma subsampling to compress the uncompressed signal. The camcorder has a clean HDMI signal and uses AVCHD compression, 1080 progressive 60fps, 8 bits per channel with 4:2:0 chroma sampling. I borrowed a colleague's Ninja 2 - a video recorder - to see if it produced video that was superior to what my camcorder could produce using its own processor. Using a really high-quality, very high bitrate codec that the pros use (and is really easy to edit) to compare? I use Vimeo quite often, and they have a setting where the video can be. Wouldn't it be great if we could take videos at 108060p using AVCHD and simultaneously shoot the same scenes I know that I can compress videos before uploading them, either online or with. Do they, given this cost, deliver good video? 108060p AVCHD video clips are difficult to play and hellish to edit.
