![]() But it would be good to know some general principles of video that I can think about this with. I realise that answers to this may be best guesses, as they may well require more information about Avidemux and YouTube than I can give. My base and output settings were both 1920 by 1080. This is on version 26.0.2 of OBS under Windows 10. There are all kinds of filters for image and. But I don't know enough about video to see how that would matter to YouTube. With Avidemux, you can perform basic cuts, copy, paste, delete, resize, divide a file into several parts, etc. It provides multiple functionalities for video edition online such as encoding (convert videos from one format to another), cutting (cut individual portions from a video) or filtering (resize, deinterlacing, add subtitles, color correction, etc.). Apart from that, I presume differences are down to however Avidemux re-encodes cropped videos when it saves files. Avidemux is a free online video editor and an online video converter. However, it's unlikely that I made them exactly identical. The aspect ratio of the two recordings, and their absolute widths and heights, would have been roughly the same, depending on how I sized the page being recorded. So why does cropping in OBS behave differently from cropping in Avidemux? More specifically, what information is YouTube using to decide the displayed width and height of uploaded videos, and why do the two cropping methods not deliver the same information to it? In contrast, the Avidemux-cropped version had no such spaces. The tool lets you edit files up to 500 MB for free. When I'd uploaded it to YouTube and made it public, it was smaller than I'd expected, with big black spaces round the outside. Step 1 Upload a video Select a file for resizing from your Mac or Windows computer, iPhone or Android phone, Google Drive or Dropbox account. So I used OBS's ALT-Drag to resize the red box so it just fit round my animation, then recorded the result. So I tried that instead, as it would save me time. But yesterday, I found out how to crop in OBS by using ALT-Drag. ![]() If you choose this method, you will be required to transcode the file. You probably should be using 128kbps AAC for stereo audio. To hit a video target bitrate, a two-pass encode is required. ![]() The best way to determine this is to do a short test-encode. I've been making YouTube videos of these by using Display Capture in OBS, then cropping the resulting videos in Avidemux using its Crop Filter. You will not be able to scale the pixels and change SAR without applying a video filter. 1 March 04, 2021, 12:27:48 PM encoding hevc on cpu is going to be slow, it may be preferable to use x264-high (maybe with -slow option) and increase bitrate a bit. I have an animation engine that runs in my web browser and animates cartoons. ![]()
