I don’t know if I was supposed to take the proxy video out of the newly created subfolder and put it in the folder together with the original 4K file since your instructions say to “make sure the proxy-file and the original-file are in the same folder” but since the program creates a subfolder for the proxy I just left it as is. Then when I hit to replace the proxy video with the original file it created a new mlt file, the back up, but when I opened Shotcut with the original mlt project file it did not replace the proxy with the original. I left the proxy video in that newly created sub folder and left the original 4K file in the folder just before the subfolder. When I clicked to create the proxy it created a new subfolder with the proxy video in it. So I specified I created a new folder and put a 4K video file in there. The program doesn’t ask you to identify specific files it seems just folders. I know I missed something in the directions. I wasn’t able to get the program to replace the proxy files with the original files in my test. 2.021 increase the quality for 360p/720p a little bit.2.021 add video formats support to:".avi.Because of the codec changing, now add.Pass-through audio streams, remove the “lossless audio” option.Add 1080p intermediate and full-resolution format options.Major proxy codec changes, using “MPEG-4 Part 2” instead of “H264 i-frame-only”, explained in post 70 Proxy_videos are ~ 1/3 of file size comparing to earlier versions, faster and smoother.V1.102 adding notification sounds when conversion finishes.v1.044 fixed the “width not divisible by 2” conversion issue.v1.043 fixed a file-name-lock issue when generating proxy directly on slow sd cards.v1.043 now ffmpeg runs in low priority mode.v1.042 change the included ffmpeg from nightly version to stable version. The proxy video is now 2 times larger but it is much clearer and useful. (The quality was super low with no deblock so the proxy video was full of tiny blocks losing all the details, unable to preview the result of colour grading and adjustments properly). v1.041 Improve the proxy video quality.The existing converted proxy_files will be skipped, the unfinished/interrupted/new files will be converted again. You can continue the conversion anytime later (simply run it again). Add a wrapper around ffmpeg to handle the incomplete output proxy files, meaning: now you can close/kill/shutdown the conversion process without any trouble.Change the proxy audio codec to ac3, as reports saying its better for smooth editing.Now this project is marked as final ~ unless major changes are needed in the future. Cosmetic changes, more tips and notices.Change the encoder profile from superfast to ultrafast ~ another 10% speedup.Include ffmpeg so this tool is fully portable now.Add file number and modify number displays so users can spot if something goes wrong.Allowing mixed editing with proxy_videos and original_videos.Change the output proxy_videos into a sub-directory named “ fastproxy”.mlt file to restore to the original high quality source videos for the final “export”. Once finished the editing, we hack the project. So we use a same-content but low-resolution videos (called proxy) to do the same editing job. This little tool made my life so much easier, so here I share.įor people who don’t know what the proxy-editing means: If your video is too big or your computer is too old then your Shotcut GUI will be choppy and laggy. It is faster and the file it generates is much smaller (high quality lossy, qscale=3). You can use it as a proxy, or you can use it as an “intermediate” to edit/export your 1080p video directly (without using button 2)įull-Resolution is similar to the Shotcut build-in “edit-friendly conversion”. zooming in)ġ080p is slower, bigger but much finer than 720p. Make Proxy(button 1) => Do Shotcut editing using Proxy => Replace Proxy with original(button 2) => Export.ģ60p is for old computers with 1080p monitors, or you are going to add lots of filters on video clips and still want the GUI to be super smooth.ħ20p is for more powerful computers, or you want to see some details during editing(eg. mlt project file (after you finish editing with the proxy_videos and are ready to export the high-quality final movie). Button 1, Batch create proxy_videos in a sub-folder named “ fastproxy” (proxy videos are 360p/720p i-frame only smooth editing format)īutton 2, “1-Click” automatically restores the proxy_videos back to the original_videos in your.
