As I suspected, the resize filter in CapCut uses the GPU for considerable speed-up. With Shotcut I used the Default preset for exporting (quality = 55%) and did exports using Hardware & Software, Parallel Processing and No Parallel Processing. I just figured out how to put a resize filter (110%) on the clip in CapCut and used the same factor for the Size, Position, Rotate filter in Shotcut. The default (quality VBR 55%) results were both comparable to the Av Bit-rate results regarding viewability.Īlthough mediainfo reported the CapCut video as Constant Framerate, when I input it into Shotcut it reports it as Variable Framerate! If Shotcut could have used 65% of the GPU, rather than 12% it would have done the encoding faster than CapCut 47s X 12 / 65 = about 10s. I suspect that CapCut uses the GPU heavily for filters too, while Shotcut doe not (normally) use the GPU-based filters). The main difference between CapCut and Shotcut is the use of the GPU (65% vs 12%-15%). | | Av Bit-rate | Av Bit-rate | Av Bit-rate | Qual=55% | Qual=55% | | | | Hardware | Software | Hardware | Software | Exported it in several formats with Shotcut (Av-Bitrate: 12.8Mb and Quality based VBR 55%)) Hardware-encoding, Software-encoding, parallel processing always enabled. Exported it in CapCut (Av Bit-rate: 12.8Mb).I did the experiment Brian suggested on my 6-Processor AMD Rizen 5 4500U system with integrated Radeon graphics. Shotcut is developed (mainly) by Dan and Brian with an annual revenue of $0. In both cases the same file size + encoding time.ĬapCut is developed by ByteDance, a company with 130,000 employees and a revenue of $60Billion per annum. In Shotcut (win64-221221 portable) it makes no difference whether I switch on hardware or software encoding. How can this serious difference in encoding time occur? Shotcut = creates 125 MB file in 14 minutes ( 840 seconds).ĬapCut = creates 129 MB file in 45 seconds.Īll exported films look the same in terms of quality. Time of export directly one after the other (Shorcut, CapCut, VSDC then for comparison CapCut, VSDC, Shotcut).Settings for the export (codecs 5 mbit Hardwareenc).Filters (4 x text, all clips enlargement 110% no rotation, 1 clip slow motion).I have created 1 identical project each with Shotcut, CapCut, VSDC Pro. I know that there have already been many discussions about exports, but I cannot explain the following difference:
